Ghent features
Background
• Head Department of Educational Studies
• 11 years Dutch Open University
• International collaboration (Cambodia, China,
Ecuador, Mozambique, Tanzania, Uganda,
Vietnam, Zimbabwe, …)
Background
• Topics (among others): higher
education, ICT, innovation
management, evidence based approach
• Our own instructional aproach is
object of study: elearning, peer
tutoring, coaching, collaborative
learning …

E-Learning
• The integrated use of Information and
Communication Technologies (ICT) in Higher
Education
– Logistics
– Administration
– Educational impact
(Laurrilard (2005, p.72)

E-learning
• Research literature not univocal:
“Whilst the benefits of eLearning are
highly prophesized, the many
implications of implementing an
eLearning program require careful
consideration”
O’Neill, Singh and O’Donoghue (2004)
7
E-learning
• “the creation of sound pedagogic
practice is often flawed or missing
completely and activities constructed
service the technology rather than
student or learner progression or
association.”
O’Neill, Singh and O’Donoghue (2004)

E-learning ~collaborative learning
• Present contribution
• E-learning:
–

–
–
Focus on collaborative learning
Focus on “pedagogies”
Focus on evidence-based practices
Focus on cognitive benefits
9
Collaborative learning
• Cognitive benefits:
– Performance (tests, exams)
– Levels of cognitive processing
10
Collaborative learning: CSCL
• On-line collaboration
• What is the theoretical base to ground
assumptions about impact on cognitive
processing?
11
12
« Collaborative learning is in the
air »
« Everyone wants it. It is the
instructional strategy, perhaps the
strategy of the decade »
13
Collaborative learning without ICT
Slavin (1996)
Johnson & Johnson (1996)
14
Collaborative learning with ICT: CSCL
• Computer Supported Collaborative
Learning (CSCL) does not
systematically produce positive
learning outcomes (Dillenbourg 2002)
Interactive
Flat
15
But does this invoke relevant
learning?
• Collaboration does not lead automatically
to high quality learning.
• There is a need guidance and online
support in CSCL settings that is
comparable to the need of classroom
support in face-to-face settings (Lazonder,
Wilhelm, & Ootes, 2003).

– Learner characteristics
– Group characteristics
– Task characteristics

CSCL: task characteristics
• Scripting ~ adding structure to the
task:
– adding specific goals for the learners,
classifying task types, adding task
prescriptions, or pre-structuring the task.
• Scripting effective to improve
collaboration (Pfister & Mühlpfordt,
2002).

CSCL scripting: tagging
35
CSCL scripting: tagging
• Aims of tagging:
–obliges students to reflect on nature of
contribution
–taggs improve outline of discussion and
indicate predominance or absence thinking type
• Example: De Bono’s (1991) thinking
hats to develop critical thinking
36
CSCL scripting: tagging
• Garrison (1992) identifies five stages
of critical thinking:
– Problem identification
– Problem definition
– Problem exploration
– Problem evaluation/applicability
– Problem integration

Tagging
• Experimental condition
–more focused discussions (F(1, 415)=1550.510; p<.001)
–more new info and ideas (F(1, 352)=21.955; p<.001)
–more linking facts ideas (F(1, 31)=3.024; p<.092)
41
Impact of tagging
• Multinomial logistic regression:
– experimental condition increases probability of
engaging in discussions
– experimental students post 2.73 as many new
problem-related information to the discussion
– experimental students 2.95 times more likely to
add new ideas
– linking ideas and critical assessment occur
rarely. Only in experimental condition.

CSCL: learner characteristics
• Chinese students
– do not perceive CSCL more positively.
– report lower level of computer competence and
internet use.
• Chinese students not used to socialconstructivist learning approach.
• Strong emphasis on examination
scores and competition

CSCL: support needs
E-moderating model
(Salmon, 2000)
53
CSCL: support needs
• Vygotsky ‘zone of proximal
development’ (Vygotsky,1978).
• Peer tutoring in CSCL
– as ‘people from similar social groupings who
are not professional teachers, helping each
other to learn, and learning themselves by
teaching’ (Topping, 1996, p. 322).
54
CSCL: support needs
• Tutors behave differently !
55
CSCL: support needs
56
Conclusions
• E-learning: potential of CSCL
• Evidence-based CSCL practices
• Validate of design CSCL-principles
– group (size and level of interactivity)
– task (scripting)
– characteristics of the individual learner
(motivation, attitudes, culture, support needs)
