CHAPTER II REVIEW OF RELATED LITERATURE 2.1 Studies Related to ‘Division’ 2.2 Studies Related to Difficulties in Learning Mathematics 2.3 Studies Related to ‘Mathematics Learning’ Except Experimental 2.4 Experimental Studies Related to Mathematics Showing Effectiveness of Different Strategies on Learning Mathematics 20 REVIEW OF RELATED LITERATURE Every piece of ongoing research needs to be connected with the work already done, to attain an overall relevance and purpose. The review of literature thus becomes a link between the research proposed and the studies already done. It tells the reader about aspects that have been already established or concluded by other authors, and is giving a chance to the reader to appreciate the evidence that has already been collected by previous research , and thus projects the current research work in the proper perspective. Here the investigator had collected a lot of studies related to different aspects of mathematics teaching and had arranged in the following sections (i) Studies related to ‘Division’ (ii) Studies related to difficulties in Learning Mathematics (iii) Studies related to ‘Mathematics Learning’ except Experimental (iv) Experimental studies related to Mathematics Showing Effectiveness of Different Strategies on Learning Mathematics. 2.1 Studies Related to “Division” Brauwer and Wim (2009) observed strong developmental paralles between multiplication and division among 8-years old children. The results are in line with strongly interconnected memory network for multiplication and division facts, at least in young children. Cavagnino and Werbrouck (2008) presented a complete analysis of the integer division of a single unsigned divided word by a single unsigned divisor word based on double word multiplication of the dividend by an inverse of the divisor. Imbo and Vandierendonck (2007) showed that executive working memory resources were involved in direct memory retrieval of both multiplication and division facts. 21 Putten (2007) found that since 1987 the Dutch primary school children’s arithmetic skills have been shown to be declining. They are making an increasing number of mistakes with written addition, subtraction, multiplication and division. Lautert and Spinillo (2006) concluded that the understanding of the remainder plays an important part in the understanding of ‘division’. Okazaki and Koyam (2005) suggested that children’s explanation based on two kinds of reversibility (inversion or reciprocity) are effective in overcoming the difficulties/ misconceptions related to division with decimals. Son (2005) found that there is a gap between learning goal (intended curriculum) and problem presented in text books (potentially intended curriculum). Mattanah et al. (2004) discussed the role of authoritative parenting, parental scaffolding of long division maths problems as a tutoring strategy that may promote academic competence in school-aged children. Booker et al. (2004) suggested that in some classrooms, the formal teaching of the ‘division’ concept and ‘algorithm’ is based on memorized rules. Lautert and Spinillo (2004), Spinillo and Lautert (2002), Squire (2002), Correa, Nunes and Bryant (1998), Nunes and Bryant (1996) and Silver Shapiro and Deutsch (1993) revealed that (i) Children ignore the reminder or suggested that it be removed from the process of resolution, in the belief that the remaining elements are not part of divison. (ii) Children try to distribute the remainder among some of the part or include it in one of the parts in which the whole has been divided into ; or (iii) They try to include the remainder in a new part Anghileri (2001) identified that increase in the use of the standard algorithm of division led to many errors and only half of the attempts to use this strategy in the second test were successful. Tirosh (2000) concluded that teacher education programmes should attempt to familiarize prospective teachers within common, some times erroneous, 22 cognite processes used by students in dividing fractions and the affects of use of such process. Anne (2000) discussed the role of measurement (quotient) in division in justifying divisibility results and demonstrates one way that this connection can be exploited to strengthen student understanding of multiplication and division Neuman (1999) concluded that formal division, understood as related to every day situations, only develops in interplay with informal knowledge. Kate and Judy (1998) revealed that students who are encouraged to use invented strategies for multiplication and division based on number relationships have a better understanding of the meaning of those operations and more successful in extending their knowledge proportional reasoning tasks than are those students who are taught conventional procedures exclusively . Mulligan and Mitchelmore (1997) found that the students used 3 main intuitive models: direct counting, repeated addition, and multiplicative operation. A fourth model, repeated subtraction, only occurred in division problems. Results showed that children acquire an expanding repertoire of intuitive models and that the model they employ to solve any particular problem reflects the mathematical structure they impose on it. Alexander (1997) revealed that students concepts of rational number operations of multiplication and division are enriched by participating in a 5 week teaching experiment Mulligan and Mitchelmore (1997); Tirosh, Graeber and Glover (1990), Booker et al. (2004) suggested that inappropriate language confuses learners and strongly hinders their understanding of the division concept. Subramanian and Singh (1996) found that the students committed six types of mistakes in addition, eight types of mistakes in multiplication and six types of mistakes in division. It was found that the poor concept of carrying over, poor concept of zero, poor concept of multiplication, introvert behaviour and lack of writing skills etc were observed as possible cause of mistakes committed by the students. 23 Dash (1996) found that the remedial intervention in solving different types of problems on multiplication and division was more effective, the average performance of children after remedial instruction was significantly higher than the same before the instruction. Silver and Mary Lee (1994) concluded that although, some aspects of division, such as its connection to different types of problem, its relationship to multiplication, were fairly well understood by most of the subject in the study, limited or flawed understanding was also noted in many different areas. Simon (1993) indicated that the prospective teachers’ conceptual knowledge was weak in a number of areas including the conceptual underpinnings of familiar algorithms, the relationship between partitive and quotitive division, the relationship between symbolic division and real-word problems and identification of the units of quantities encountered in division computations. Ball (1990) reported that the prospective teachers’ knowledge was generally fragmented and each case of division was held as a separate bit of knowledge. Graeber and Tirosh (1990) indicated that students of fourth and fifth graders hold the misconceptions such as ‘multiplication always makes bigger’. Tirosh and Graeber (1989) argued that one of the misconception that a majority of pre-service teachers appear to hold explicitly is that in division the quotient must be less than the dividend. Silver (1986, 1988) and Silver, Mukhopadhyay and Gabriele (1992) investigated that students’ failure to solve division problems with remainders can be attributed, at least in part, to their failure to relate computational results to the situations described in the problem. Carpenter et al. (1988); and Hart (1981) argued that children’s success rates on various task related to such division are usually very low. Fendel (1987) and Payne (1976) opined that Division of fraction is often considered the most mechanical and least understood topic in elementary school. 24 Greer and Magan (1986) and Graeber, Tirosh and Glover indicated that a substantial portion of preservice teachers (1989) have difficulty in selecting the operation needed to solve multiplication and division problem involving decimals. Silver (1986) revealed that only about 35% of the sixth graders in California was able to answer correctly to a division problem appeared on the 1983 version of the California Assessment Programme (CAP) Fischbein et al. (1985) confirmed the impact of the repeated addition model on multiplication and of the partitive model on division. National Assessment of Educational Progress (NAEP) (1983) has been documented the failure of American students to succeed in solving problems involving whole number division with remainders. Bigalke, and Haseman (1978) and Padbery (1978) argued that for the arithmetic of fractions there exists many ruels and these are more complicated than those for natural numbers. If these rules are introduced too early, there is a danger of their being used mechanically and without thought. Grouws and Good (1976) suggested that the factors associated with third and fourth grade children’s performance in solving multiplication and Division sentences are place holder position and other aspects of sentence writing. 2.2 Studies Related to Difficulties in Learning Mathematics Pal (2009) concluded that many difficulties that children face in leaning are rooted in the lack of understanding of lower level concepts and lack of clarity about different ruels that are often conflicting can lead to misconceptions and affect mathematical learning. Wang, Du and Liu (2009) identified two types of learning difficulties: learned helplessness and defensive attribution. The students enhanced their learning in mathematics with the use of appropriate strategies in the interventions. Acha (2009) concluded that children’s learning processes are hindered by limited working memory. 25 Morgan, Farkas and Wu (2009) indicated that the children persistently displaying mathematics difficulty (MD) (i.e. those experiencing MD in both fall and spring of Kindergarten ) had the lowest subsequent growth rates, children with MD in spring only had the second –lowest growth rates and children with MD in the fall only (and who had thus recovered form their MD by the spring of Kindergarten) had the next lowest growth rates. The children who did not have MD in either fall or spring of Kindergarten had highest growth rates. Yang and Li (2008) indicated that 3rd grades in Taiwan did not perform well on each of the five number sense components and they appeared worst on the performance of ‘Judging the reasonableness of computational results.’ Olive and Caglayan (2007) examined 8th grade students’ coordination of quantitative units arising from word problems and results indicated that the identification and coordination of the units involved in the problem situation are critical aspects of quantitative reasoning and need to be emphasized in the teaching-learning process. Blanco and Garrote (2007) concluded that students find two types of difficulty in dealing with inequalities. On the one hand, arithmetic is still the fundamental referent for those students who make errors in the algebraic procedures and, on the other, the absence of meaning is the underlying cause of the failure to understand the concepts and the algebraic process. Petrill and Plomin (2007) revealed that approximately 6 to 10% of individuals in general population have a persistent mathematical learning disability (MLD) or dyscalculia. There is evidence that MLD is biologically based and has genetic influences. Voutsina and Ismail (2007) provided evidence of the nature of understanding of selected concepts of single-digit addition held by young children (of primary school age) who have difficulties in mathematics or are identified by a computer based standardized test as being at risk of dyscalculia. Dowker (2004) strongly supports the view that children’s arithmetical difficulties are highly susceptible to intervention and concluded that 26 individualized work with children who are falling behind in arithmetic has a significant impact on their performance. Dowker (2004) found out some children could remember many number facts, but seemed to lack strategies (including suitable counting strategies) for working out sums when they did not know the answer and some other children could deal with single-digit arithmetic but had serious difficulty in achieving even limited understanding of tens, units and place value. Stewart et al. (2003) have developed strategies for dealing with classes that include a significant number of children with mathematical difficulties and techniques that she has used include multi-sensory teaching of mathematics, involving motor activities. Koy and Yeo (2003), Miles and Miles (1992), Chinn and Ashcroft (1998) and Yeo (2003) pointed out that most dyslexic pupils have difficulty with longterm memory for facts, working memory difficulties, sequencing difficulties and difficulties with language, including mathematical language. Jordan, Hanich and Kaplan (2003) concluded that the children with poor fact mastery showed little improvement on timed number fact test in over a year, but showed normal progress in other aspects of mathematics. Kroes Bergen and Van Luit (2002) reported that both the math intervention, guided versus structured instruction, improved more than the students of the regular instruction and guided instruction appeared to be more effective for low performing students than structured instruction and especially for those students in regular education. Poustie (2001) discussed ways of helping pupils with mathematical difficulties, which can be applied within classroom, in the context of individualized or small group tuition and /or by parents helping their children at home. Yeo (2001) reported that while many dyslexic children have difficulties only with those aspects of arithmetic that involves verbal memory, some dyslexic children have more fundamental difficulties with ‘number sense’. 27 Mukherjee (2001) argued that failure to take into account the children’s intuitive, informally learned pre-school mathematics. Knowledge is likely to result in confusion and fear in learning mathematics. Potari and Georgiadu (2000) revealed that a mathematical task that was considered by an adult as easy, could also be easily understood by children and children learn mathematics through their actual involvement in variety of teaching activities. Jordan and Hanich (2000) found out that children with MD/RD (Difficulties in both reading and mathematics) performed worse than NA (normal achievement) children on all aspects of mathematics; those with MD performed worse than NA children only on story problems. Fei (2000), Russell and Ginsburg (1984), Siegler (1988), Geary and Brown (1991), Ostad (1997) and Cumming and Elkins (1999) showed children with mathematical difficulties to be more consistently weak at retrieving arithmetical from memory than at other aspects at arithmetic. Paria (1999) found that the main errors identified were conceptual and computational difficulty in selected topics. Gonzalez and Espinel (1999) revealed that children whose arithmetical achievement was much more worse than would be predicted from their IQ. Jordan and her colleagues and Geary et al. (1999) suggested that children with combined mathematical and reading disabilities tend to perform badly on more aspects of mathematics than children who only have mathematical difficulties. Ash Craft and Hopko (1998), Fennema (1989) and Hembree (1990) opined that many people develop anxiety about mathematics, which can be distressing problem itself and also inhibits further progress in the subject. This is rare in young children and become more common in adolescence. Macaruso and Sokol (1998) found that the arithmetical difficulties were very heterogeneous, and that factual, procedural and conceptual difficulties were all represented. 28 Grauberg (1998) noted that pupils with language difficulties tend to have difficulties in particular with (i) symbolic understanding (ii) organization (iii) memory and in addition, language difficulties will directly affect the child’s ability to benefit from oral or written instruction and to understand the language of mathematics. Szanto (1998) found that adults with arithmetical difficulties performed in a similar fashion on both computational skills and arithmetical reasoning to normally achieving adolescents and children who were at a similar overall arithmetical level. Pal et al. (1997) were found that most of the errors committed by primary school students were due to a process of dualism. Swarnalekha (1997) revealed that learning through games gives remarkable improvement in the area of problem-solving and area of mathematics learning were attained by paying attention to the language comprehension skills and other non-scholastic areas. Miller and Mercer (1997) discussed the need to take mathematical difficulties into account, even while attempting to raise overall standards and they emphasize the importance of accommodating diversity, and adopting teaching to individual strengths and weakness. Ostad (1997) concluded that at all ages, children without mathematical difficulties used a far wider variety of strategies than those with mathematical difficulties, and the differences increased with age. Jordan and Montani (1997) opined that if there are differences between specific and non-specific mathematical difficulties, they are probably in the direction of specific difficulties being milder and less pervasive than non-specific ones. Shalev, Manor, Amir, Weirtman and Gross-Tsur (1997) found no difference in the types of mathematical difficulty demonstrated by dyscalculic children with higher verbal versus higher non-verbal IQ. 29 Fazio (1994) argued that the children with spoken languages and communication difficulties usually have some weakness in arithmetic, but once again some components tend to be affected much more than others Rourke (1993) proposed that verbal weakness lead to memory difficulties and non-verbal weakness lead to logical difficulties. Tall and Mohamad (1993) illustrated the difference in qualitative thinking between those who succeeded and those who fail in mathematics, illustrating a theory that those who fail are performing a more difficult type of mathematics (coordinating procedures) than those who succeeded (manipulating concepts). Wong and Lai (1993) concluded that pedagogical content knowledge is the crucial factor leads to effective mathematics teaching. Sinha (1993) found out that the angular method was more effective than traditional method in improving VI class students. Skill in simple addition and it also was helpful in developing favorable attitudes towards learning mathematics. Swan (1993) reported on a conflict teaching approach to involve students in discussion of and reflection on their errors and misconceptions. Temple (1991) reported that one child who could carry out arithmetical calculation procedures correctly but could not remember number facts and another child who could remember the facts but not carryout the procedures. Russell and Ginsburg (1984) found that the difficulties with word problem solving, as well as with memory for facts of 9 year old children who were described by their teachers as weak at arithmetic. Hart (1981) and her team revealed that secondary school pupils have many difficulties, both procedural and conceptual, with many mathematical topics, including ratio and proportion; fraction and decimals; algebra and problems involving area and volume. Ginsburg (1977) examined children who were failing in school mathematics and found out (i) some had a good informal understanding of number concepts, but had trouble in using written symbolism and standard school methods. (ii) Some had particular difficulties with the language of mathematics 30 (iii) some children appeared to have very limited understanding at first sight, but still had a good understanding of counting techniques and principles. Weaver (1954) argued that interventions that focus on the particular components with which an individual child has difficulty are likely to be more effective than those which assume that all children’s arithmetical difficulties are similar. 2.3 Studies Related to Mathematics Learning Except Experimental Venkat and Brown (2009) examined the implementation of the mathematics strand of the key stage 3 strategy and revealed that both setting and whole–class teaching and mixed ability grouping and individualized learning school achieved highly in relation to similar schools. Kramarski and Mizrachi (2008) showed that the online discussion embedded within metacognitive students significantly outer performed the faceto-face discussion without metacognitive guidance students, who in turn significantly outer performed the online and face to face discussion without metacognitive guidance students on mathematical, literacy of standard tasks, reallife tasks and various aspects of self –regulated learning. Griffin and Jitendra (2008) concluded that both SBI (Scheme Based Instruction) and GSI (general strategy instruction) improved word problemsolving and computational skills. Yang (2005) concluded that 6th graders inclinations to use paper-andpencil procedures narrowed their thinking and reasoning powers: this heavy reliance on written algorithms seemed to be a major impediment to development of number sense. Xinma (2005) indicated that age was critically important for fast growth in mathematics achievement. Son (2005) found that there is a gap between learning good (intended curriculum) and problems presented in textbooks (potentially intended curriculum) of mathematics. 31 Chill et al. (2005) explored and found that teachers’ mathematical knowledge was significantly related to student achievement gain. Arbaugh and Brown (2005) indicated that the high school mathematics teachers showed growth in the way that they consider tasks and that some of the teachers changed their pattern of task choice. Muijs and Reynolds (2003) examined the effects of the use of learning support assistants and results did not provide much support for he use of classroom support assistants as a way of improving the achievement of low achieving students, or as a means of increasing child-adult contact without employing more teachers, and it would seem ill-advised to seek to solve teacher shortage by replacing them with an army of learning assistants. Baxter et al. (2001) suggested that both the organizations and task demands of the reform classrooms presented verbal and social challenges to low achievers that need to be addressed if those students are to benefit from reformbased mathematics instruction. Manouchehri and Goodman (2000) proposed that teachers’ mathematical knowledge was the greatest influence on how they evaluated and implemented the textbook. King (1999) exposed that class size has an impact on the use of class time, both instructional and non-instructional . Fuchs et al. (1997) argued TFG (task focused goal treatment) students were enjoying and benefitting from TFG, chose more challenging and a greater variety of learning topics, and increased their effort differently. Patel (1996) argued that the lesson idea programme in mathematics could influence the affective behaviour of the experimental group, while it did not have significant impact upon the behaviour of boys and girls. Kumar (1996) concluded that less than 20% of the teachers held positive attitude towards mathematics. Goel (1996) found that the total no. of errors committed by children in different grades (Class I to IV) varied significantly. 32 Mayer et al (1995) compared the lesson on addition and subtraction of signed whole numbers in three seventh-grade Japanese mathematics text books with the corresponding lesson in four US mathematics textbooks. The results indicated that Japanese books contained many more worked-out examples and relevant illustrations than did the US books, whereas the US books contained roughly as many exercises and many more irrelevant illustrations than did the Japanese books. Confrey and Scarano (1995) showed that 10 and 11 years old exceeded the comparative performance of 14 and 15 years old on ratio and proportion test items. Hoffer (1992) revealed that Ability grouping appears to benefit advanced students, to harm slower students and to have a negligible over all effect as the benefits and liabilities cancel each other out. Christensen and Cooper (1991) indicted that practice produced more effective learning and more effective strategy use. Sowell (1989) showed that mathematics achievement is increased through the long-term use of concrete instructional materials and that student’s attitudes towards mathematics are improved when they have instruction with concrete materials provided by teachers knowledge about the use. Freeman and Porter (1989) revealed that there were important differences between the curriculum of the text and teachers’ topic selection, content emphasis and sequence of instruction. Athappilly et al. (1983) concluded that there have not been many detrimental effects of ‘new mathematics’ either on achievement or on attitude. 2.4 Experimental Studies Related to Mathematics showing Effectiveness of Different Strategies on Learning Mathematics Paksu and Ubuz (2009) found that drama-based instruction had a significant effect on student’s achievement and make learning easy and understand better by providing the opportunity to contextualize geometry concept and problems. 33 Thangarajathi (2008) revealed that the mind mapping technique is more effective than the conventional method in teaching mathematics at high school level. Singh (2008) indicated that jurisprudential inquiry model group students were attaining significantly higher mean scores than conventional groups students for verbal fluency as well as its four areas. Sharma and Sharma (2008) revealed that STAD (student teams achievement division) approach has greater effect. Oyesoji and Taiwao (2008) concluded that participants in the experimental conditions performed better than their counterparts in the control group on the measure of academic achievement and vicarious reinforcement was found to be more effective than contingency contracting in enhancing academic achievement of impulsive participants. Kumar and Sini (2008) showed that brain compatible learning is more effective than the existing method of teaching. Jain and Castro (2008) investigated the robustness of strategies intervention model accompanied with mediated learning experience with students who have poor mathematical achievement and indicated that the intervention significantly enhanced the mathematical achievement of participants in the treatment group. Hoffman et al. (2008) concluded that the standardized test results indicated superior performance for co-educational students. Chiou (2008) revealed that (i) adopting a concept mapping strategy can significantly improve students’ learning achievement compared to using a traditional expository teaching method and (ii) most of the students were satisfied with using concept mapping in an advanced accounting course. Thangarajathi and Viola (2007) concluded that there is significant difference between the post-test scores of students in cooperative learning method group and conventional method group in learning mathematics at high school level. 34 Mary and Raj (2007) found that the concept mapping method and traditional lecture method did not make any qualitative difference. Hanock (2007) revealed that students exposed to performance assessment achieved some what higher scores on the final examination and demonstrated significantly higher levels of motivation to learn than the students evaluated by traditional paper-and-pencil tests. Ayodhya (2007) disclosed that the polya’s heuristic approach is more effective than the conventional method in developing problem-solving skills. Wolgemuth and Leech (2006) showed that FDK (Full day Kindergarten) students demonstrated significantly higher achievements on mathematics and reading. At the end of kindergarten than did their HDK (Half-day kindergarten) counterparts, but that advantage disappeared quickly by the end of first grade. Wighting (2006) concluded that using computers in the classroom positively affects students’ sense of learning in a community. Sungur and Thekkaya (2006) revealed that PBL (problem based learning) students had higher levels of intrinsic goal orientation, task value, use of elaboration learning strategies, critical thinking, meta cognitive self-regulation, effort regulation, and peer learning compared with control-group students. Veeman et al. (2005) examined the effects of a teacher-training programme on the elaborations and affective –motivational resources and the programme showed moderately positive effects on use of elaborations among the treatment dyads. Dyads with experience in cooperative learning achieved more than dyads without such experience. Kaufmann et al. (2005) revealed significant learning effects in the children who participated in the numercacy program particularly for counting sequences and mental calculation. Isiksal and Askar (2005) concluded that the Autograph group had significantly greater mean scores than the Traditional group, while no significant mean difference was found between the Autograph and Excels groups, and between the Excel and Traditional groups with respect to mathematics selfefficacy. 35 Desimone et al. (2005) suggested that most of the perceived barriers related to teachers autonomy, trade-offs with computational strategies, student achievement, class size and teacher qualification are not impediments to the use of conceptual teaching strategies in other countries and the comparative findings hold promise for alternative paradigms for organizing better mathematics instruction in the United States. Nye et al. (2004) found larger effects on mathematics achievement than on reading achievement. Kroesbergen et al. (2004) showed that the math performance of students in the explicit instruction condition improved significantly more than that of students in the constructivist condition, and the performance of students in both experimental conditions improved significantly more than that of students in the control condition. Fuchs et al. (2004) examined the effects of a dyadic peer-mediated treatment on kindergarten children’s mathematics development and result indicted that treatment implementation was strong for most, but not all. Kramarski and Mevarech (2003) learning combined with metacognitive concluded that the cooperative training group significantly outer performed the individualized learning combined with meta cognitive training group and which in turn significantly outer performed the cooperative leaning and individualized learning groups on graph interpretation and various aspects of mathematical explanation. Scott Baker et al. (2002) indicated that different types of interventions led to improvements in the mathematics achievement of students experiencing mathematics difficulty including the following (a) providing teachers and students with data on students performance; (b) using peers as tutors or instructional guides; (c) providing clear specific feed back to parents on their children’s mathematics success; and (d) using principles of explicit instruction in teaching maths concepts and procedures. Sahlberg and Berry (2002) concluded that there is no unanimity about the effects of small group learning on student achievement in school mathematics; it 36 seems that it produces at least equal academic outcomes among all students compared to more traditional methods of instruction. Desimone et al. (2002) found that professional development focused on specific instructional practices increases teacher’s use of practices in the classroom. Sivan et al. (2000) disclosed that active learning made a valuable contribution to the development of independent learning skills and the ability to apply knowledge. Molia (1999) found that inductive thinking model is to be effective in improving the achievement in mathematics. Kumudha (1999) found that the concept mapping methods is very effective in the achievement of standard XII students. Bala Subramanian (1999) concluded that cognitive modeling on learning of mathematics is to be effective in enhancing achievement in mathematics at under graduate level. Orman (1998) suggested that proper development and application of educational multimedia computer programmes may benefit instrumental education. Ben et al. (1998) revealed that after instruction on spatial visualization skills, fifth through eighth grade students profited considerably form instruction and the gain was similar for boys and girls despite of initial sex differences. Nalage (1997) explored that teaching of mathematics became more effective when it was done with the help of teachers handbook. Mevarech and Kramarski (1997) focused on (i) in-depth analysis of students information processing under different leaning conditions and (ii) the development of students’ mathematical reasoning over a full academic year. Results of both studies showed that improve students significantly outer performed the non treatment control groups on various measures of mathematics achievement. 37 Fuchs et al. (1997) indicated that irrespective of type of measure and type of learner, students in peer tutoring classrooms demonstrated greater reading progress. Chel (1997) tried out ‘seeing is believing’ principles in teaching mathematics at the secondary level and found it to be more effective than the conventional method. Goel (1996) revealed that the performance of students at representational level was better than their performance at abstract level. Reddy and Ramar (1995) proved that the multimedia modular approach did help the poor achievers in doing better in mathematics. Bussama (1993) has studied the effect of simulation technique in teaching mathematics and found that it is more effective than traditional method of teaching mathematics. Singh (1992) concluded that computer-assisted instruction was always found superior, but the gain were more in the case of good students and there was a definite positive change of attitude towards learning mathematics on the part of both boys and girls due to the use of computers. Prabha (1992) has found that programmed learning of mathematics is superior to conventional learning of mathematics and that mother’s and father’s education significantly affect programmed learning. Even parents’ income and cast effects significantly the learning of mathematics. Kulik et al. (1990) showed that mastery learning programmes have positive effects on the examination performance of students in colleges, high schools and the upper grades in elementary schools. Spencer (1989) revealed that programmed instruction as a classroom method of teaching and learning in Ibadan is likely to have a more facilitating effect on student’s achievement. Peterson et al. (1987) examined the long-term impact of retention/ promotion decision on the academic achievement of primary grade students and results of same year comparisons indicated that retained students significantly 38 improve their relative class standing by the end of the retained year and in some cases they maintain this advantage over a 2-year period. However, after 3 years there are no differences between retained and promoted students. Sqrensen and Hallinan (1986) showed that (a) ability grouping provided fewer opportunities for learning than whole class instruction but greater utilization of these opportunities (b) high ability groups provide more opportunities than low group. Kallison (1986) indicated no significant effect for sequence and the study yielded a significant effect for explicit organization. Osborne (1985) suggested that experienced teachers tended to take a more ‘task oriented’ approach providing more instruction and structure and less tasks irrelevant conversation than did inexperienced teachers. Hendel (1985) compared the effect of individualized and structured curricula on the academic performance and results indicated that the two groups were indistinguishable in persistence, graduation rate, academic success and overall course selection patterns, but that they differed significantly in their evaluation at follow-up of their under graduate education. Fuchs et al. (1984) revealed that experimental teachers effected greater students achievement and (a) experimental teachers’ decision reflected greater realism about and responsiveness to student progress (b) their instructional structure demonstrated greater increase and (c ) their students were more aware of goal and progress. Coladarci and Gage (1984) indicated that the intervention did not effect significant change in training –related teaching practices or end-of year student achievement. Sharpley et al. (1983) revealed that the fifth and sixth grade tutors effectively increased the operational mathematics achievements of their tutees, the increase in tutors’ and tutees mathematics achievements being significantly greater than those of the control children. 39 Saracho (1982) argued that students who used CAI (Computer Assisted Instruction) programme had greater achievement gains than did students who participated in the regular classroom programme. Lysakowski and Walberg (1982) estimated the instructional effects of cues, participation and corrective feedback on learning. Strong effects appeared constant form elementary level through college and across socioeconomic levels, races, private and public schools and community types. Kulik and Kulik (1982) reported results from a meta-analysis of findings from 52 studies of ability grouping carried out in secondary schools. In the typical study the benefits from grouping were small but significant on achievement examination. Peterson et al. (1981) indicated that high and low-ability students benefited from peer tutoring processes that occurred in the small groups. Sefkow and Myers (1980) suggested that the backward review effect cannot be attributed solely, or even substantially, to a cueing or retrieval phenomena but rather to a strengthening or integration of the memory traces at the time of the probe. Luiten et al. (1980) showed that advance organizers have a facilitative effect on both learning and retention. Ebmeie R and Good (1979) proved instructional model based upon previous naturalistic research was effective and the nature of the interaction between student aptitudes, teacher style and instructional model helps to interpret the influences on students’ mathematics achievement. Good and Beckerman (1978) examined the functional relationship of teacher effectiveness and the achievement of high, middle and low attitude third and fourth grade students. Significant main effects were found for both teacher competence and student aptitude with no significant interaction between the two variables. Wilmut (1973) shown that attitudes have some effect in determining the outcome of the project and that in a few cases the project affects the attitudes held by the pupil. 40 MCG (1971) studied two groups of secondary school boys of below average academic ability. The control groups received traditional English teaching; the experimental group had experience of SRA Reading Laboratory 2a included in their English lessons. After nine weeks, no differences were shown in the reading performance of the two groups. Reflection on the Review of Related Studies Putten (2007), Lautert and Spinello (2006), Booker et al. (2004), Lautert and Spinello (2004), Correa, Nunes and Bryant (1998) Silver Shapiro and Deutsch (1993), Anghileri (2001), Subramanian and Singh (1996), Dash (1996) and Tirosh and Graeber (1989) concluded that (i) Since 1987 the Dutch primary school children’s arithmetic skills have been shown to be declining. (ii) The understanding of the remainder plays an important part in the understanding of ‘division’. (iii) In some classrooms, the formal teaching of the ‘division’ concept and algorithm is based on memorized rules. (iv) Children ignore the remainder or suggested that is be removed from the process of resolution, in the belief that the remaining elements are not part of division. (v) Children try to distribute the remainder among some of the part or include it in one of the parts in which the whole has been divided into. (vi) Increase in the use of the standard algorithm of division led to many errors (vii) The students committed six types of mistakes in addition, eight types of mistakes in multiplication and six types of mistakes in division. (viii) The remedial intervention in solving different types of problems on multiplication and division was more effective, the average performance of children after remedial instruction was significantly higher than the same before the instruction. 41 (ix) One of the misconceptions that a majority of pre-service teachers appear to hold explicitly is that in division the quotient must be less than the dividend. As per the reflections of the studies cited above and as per the review of all the other studies mentioned above the researcher planned to carry out this study on “Developing a Strategy for Syncopating Mathematical Skills Among Primary School Students” to see whether the new strategy developed by the researcher significantly enhances the division skills of students in Mathematics.
