This is in accordance with our national goals of education which include among others making the students: Possess basic knowledge of Science; Reason scientifically and logically; Reason objectively and not depending too much on the thinking of others; Develop the sense of curiosity and creativity; Acquire the ability to fit into the international environment. In its definite aspect and by the precision of its processes and reasoning, Physics allows the development of the mind and makes up an important component of culture essentially to people. This Advanced Level Physics Program for MCB (Mathematics-Chemistry-Biology) aims at a complete training of the student creating a good understanding of different phenomena in Physics occurring in the environment and to exploit them for better participation in the development of the society.At this level, the Advanced Level student must move from knowledge of direct experience to a level of scientific ideas governed by laws and theories. iii Physics Curriculum for Advanced Level (elective) In addition to that, Physics lessons must arouse scientific curiosity of the student and motivate a spirit of research.Teaching methods should be student-centered and primarily active, inductive and practical as opposed to the old approach that is mainly theoretically deductive. The teacher should create learning situations that need observation of facts and phenomena in everyday life or use technological and professional techniques to develop a spirit of curiosity, interest and critical thinking in students. Students should be given practical work since Physics is an experimental science. Students should also be put in a situation that requires action and research; this will allow better acquisition of knowledge and spirit of observation, cognition and synthesis of ideas. The teaching and learning of Physics at Advanced Level should be oriented towards attaining the general and specific objectives of this program in accordance to its evaluations.During the setting of these evaluations, taxonomic levels in educational objectives such as knowledge, understanding, application, analysis, synthesis and evaluation of the cognitive field should be taken into account.

INTRODUCTION Due to particular emphasis on science and technology as an engine of development, Rwanda would like to build a knowledge-based economy. In this regard, the Ministry of Education undertook the 2009 education system reform in which the system of combinations at advanced level was introduced. In this context, the REB (Rwanda Education Board) found it wise to develop Physics Curriculum for MCB Combination. In this program, the emphasis was put on the content, methodology and structure of the curriculum in order to equip learners with enough and appropriate knowledge, skills and attitudes. To meet this pedagogical orientation/need, the curriculum is presented in a three column table. The content suggested in the second column of the curriculum, has specific objectives to be attained in the first column as well as a methodological note in the third column which suggests the appropriate teaching/ learning activities to be done. To follow the Universities and Higher Learning Institutions studies such as Medicine, Agriculture, Engineering etc, REB would like to introduce Physics Course in MCB Combination. 1 Physics Curriculum for Advanced Level (elective) This curriculum also helps learners to use ICT (Information and Communication Technology) tools to support the mastery and achievement of the desired learning objectives. Technology used in the teaching and learning of Physics, for example simulation on computer, is to be regarded as a tool to enhance the teaching and learning process and not to replace teachers. At the end of detailed content of each grade, there is a proposal of lesson distribution to be taught per term 2 Physics Curriculum for Advanced Level (elective) 2. GENERAL ORIENTATION In the vision 2020, Rwanda has decided to build on knowledge – based economy, where science and the technology education and ICT skills are actively encouraged and considered as the engine for development of the country. In this frame work, the government is committed to review and design all the curricula of all levels and the teaching methodology to provide the population with knowledge, competences and attitudes for sustainable development. This present physics curriculum is a new curriculum designed for students who are doing MCB combination. The major purpose of teaching this physics curriculum to young adolescents is to help them understand natural phenomena happening on this earth. This Advanced Level Physics Program for MCB (Mathematics-Chemistry-Biology) aims at a complete training of the student creating a good understanding of different phenomena in Physics occurring in the environment and to exploit them for better participation in the development of the society. At this level, the Advanced Level student must move from knowledge of direct experience to a level of scientific ideas governed by laws and theories. 3 Physics Curriculum for Advanced Level (elective) In this new physics curriculum the teaching must be learner – centered and integrate theory and practical: laboratory manipulations, experiments, observation of real situations. The present curriculum is inspired by the following didactic principles: Principle of motivation In the beginning of every chapter, the teacher must foresee a learning situation. By analogy, at the level of the lesson, in the beginning, the teacher must endeavour to create the problem situation that place the learner in a mood of learning. Principle of activity This principle stipulates that the individual learns better if he/she is completely implicated in the action. The physics curriculum puts emphasis on a learner centered approach. It foresees in the column of learning activities, a whole set of activities among those that should be achieved by the learners themselves to reach scientific truth (laws, theories) that the traditional pedagogy has the habit to expose / impose. Principle of realization The reality gives a sense to the situation and permits to understand a situation by reference to a known and familiar context. Even though during the adolescence, an individual reaches a 4 Physics Curriculum for Advanced Level (elective) hypothetic-deductive reasoning allowing him to start from general to specific (deductive way), the teaching experience recommends even at this age the inductive way which orients the learner toward the discovery. The physics curriculum proposes and recommends the use of the learning situations and activities that are placed in a familiar, meaningful context because they evoke the lively learning situation for the learner. Principle of progression Every time start from simple to complex, from known to unknown. It is the mathematical progression. This principle makes also reference to the learner's psychological progression, his/her mental development level. Principle of cooperation In a cooperative training, the competition and the individualization don't have any place. We have a group centered on a task to achieve. Everybody is there to learn from each other, to take advantage of the enriching experience of his/her classmates. Principle of transfer By this principle, the science teaching recommends that the acquired notions should be applicable in real and new life situations. 5 Physics Curriculum for Advanced Level (elective) Principle of integration of matter The education constitutes a unit. All disciplines of Science (Biology, Chemistry, Physics and Math’s) contribute to promotion of the student knowledge, competences and attitudes and to propose some solutions to complex problems of life in general. Even those disciplines are taught separately at this level, the teacher will make reference to them during the lessons. 6 Physics Curriculum for Advanced Level (elective) 3. GENERAL OBJECTIVES BY THE END OF THE LEVEL After completion of Advanced Level Secondary Education in Mathematics-BiologyChemistry (MCB), the learner should be able to: Apply acquired knowledge, skills and attitudes in daily life problem solving ; Express him/herself in international scientific environment; Analyze situations scientifically; Analyze, explain facts and practical applications of phenomena in technology and in daily life; Identify scientific problems and suggest scientific approach to solve them; Collect, evaluate and interpret scientific data; Present results and draw appropriate conclusions; Possess knowledge and skills that would enable him /her to access studies in Physics and related courses in universities and higher institutions of learning. 7 Physics Curriculum for Advanced Level (elective) 4. METHODOLOGICAL APPROACHES The proper use of teaching resources is crucial in enabling learners to understand Physics concepts. Teachers should encourage learner’s hands–on and minds-on activities using real or concrete materials to help them gain experience, construct abstract ideas, obtain scientific findings, build self confidence, be independent and inculcate the spirit of cooperation. • • In order to assist learners in having positive attitudes towards Physics, confidence and thinking systematically, students have to be involved into the teaching and learning process. Good moral values can be cultivated through suitable contexts. Learning in groups should be emphasized to help learners develop social skills, encourage cooperation and build self confidence. Environment awareness and its conservation skills should also be developed through the teaching and learning process in the classroom by using various examples. Various teaching strategies and approaches such as direct instruction, discovery learning, investigation, guided research or other methods must be incorporated. Taking into consideration different learning abilities and styles of learners, teacher should use mainly the following approaches: Learner-centered; 8 Physics Curriculum for Advanced Level (elective) • • Use of relevant, suitable and effective teaching materials; Formative evaluation to determine the effectiveness of teaching and learning process. The choice of a suitable approach will stimulate the teaching and learning environment inside or outside the classroom. The considered suitable approaches include the following: • • • • Cooperative learning; Contextual learning; Mastery learning; Constructivism. In this curriculum, suggested various activities in all chapters may be done in groups or individually very often given as homework. Teachers should focus more on direct applications of a concept. 9 Physics Curriculum for Advanced Level (elective) 5. EVALUATION PROCESS To measure the level at which objectives are achieved the teacher has to plan continuous evaluations. Different methods of assessment that can be conducted include formative and summative evaluations. Based on the given responses, teacher can rectify learners’ misconceptions and weaknesses and also improve his/her own teaching skills. Teacher can then take subsequent effective measures in conducting remedial and enrichment activities in upgrading learners’ performances. It is also suggested to evaluate students on the basis of technical terms and problems involving direct application of concepts. 10 Physics Curriculum for Advanced Level (elective) 6.
