CSCL within education
Computers within education
p 2 ' As CSCL developed, unforeseen barriers to designing, disseminating and effectively taking advantage of innovative educational software became more and more apparent. A transformation of the whole concept of learning was required......'
E-learning at a distance
'CSCL too often conflated with e-learning, the organisation of instruction across computer networks'
Co-operative learning in groups
Dillenbourg 1999  defined the distinction between cooperative and collaborative learning roughly as follows. p3 'In cooperation, partners. Split the work, solve sub-Tasks individually and then assemble the partial results into the final output. In collaboration, partners do the work together'. i e learning cooperatively can be studied with traditional cf .CSCL methods
Collaboration and individual learning
p 3 ' The relationship between viewing collaborative learning as a group process versus an aggregation of individual change is a tension at the heart of CSCL'
' In CSCL, by contrast, learning is analysed as a group process; analysis of learning at both the individual and the group unit of analysis is necessary'
The Historical Evolution of CSCL
The beginnings
Three projects in the 90s. All shared the goal of making instruction more orientated towards meaning making. All turned to computers as resources, all three introduced some organised social activity.
From conferences to global community
Key Books p 5
From AI to collaborative support
p 6 'AI is computer software that closely mimics behaviours that might be considered intelligent if done by a human' 'Intelligent tutoring systems are a prime example of AI, because they replicate the actions of a human tutor' 'This is still an active research area within the learning sciences, but is limited to domains of knowledge where mental models can be algorithmically defined'

The role of the computer has shifted from 'providing instruction - either in the form of facts in computer-aided instruction or in the form if feedback from intelligent tutoring systems - to supporting collaboration by providing media of communication and scaffolding for productive social interaction' - scaffolding  can involve AI techniques eg by offering alternative views.
From individuals to interacting groups
The other group members no longer seen merely as a social background p7 ' the group itself has become the unit of analysis and the focus has shifted to more emergent, socially constructed, properties of the interaction'

Collaboration involves complex interacting factors therefore empirical research that investigated causal factors by controlling for other factors is generally not very successful. p7 for page 189 of Dillenbourgh et al,1996 ' Hence, empirical studies have more recently started to focus less on establishing parameters for effective collaboration and more on trying to understand the role that such variables play in mediating interaction. This shift to a more process-orientated account requires new tools for analysing and modelling interactions'

From mental representations to interactional meaning making
p 8. ' meaning making not assumed to be an expression of mental representation of the individual participants, but is an interactional achievement'
From quantitative comparisons to micro case studies
In collaborative contexts individuals visibly show their learning p 8 'the methods that people use to interact are widely shared ( at least within appropriately defined communities or cultures)' therefore case study method is popular.

p8/9 ' how can the analysis of interactional methods help guide the design of CSCL technologies and pedagogues? This question points to the complex interplay between education and computers in CSCL.
The interplay of learning and technology in CSCL
The traditional conception of learning
Thorndike - learning is measurable
Learning as a psychological phenomena with three essential features, it represents a response and recording of experience, it is change that occurs over time, it is a process that is not available to direct inspection

CSCl embraces a more situated view, p 9 'locates it in meaning negotiation carried out in the social world rather than in people 's heads'

Designing technology to support Grouo meaning making
p 9 ' No form of technology, however, no matter how cleverly designed or sophisticated, has the capacity, in and of itself, to change practice. To create the possibility of an enhanced form of practice requires more multifaceted forms of design (bringing in theories and practices from various disciplines').

p 10 ' An environment for a desired form of practice becomes so through the organised actions of its inhabitants '. i e an environment is constructed by the people who use it' and therefore in order to design we need to understand how people use these environments.

'CSCL research  has both analytic and design components. Analysis of meaning making is inductive and indifferent to reform goals. It seeks only to discover what people are doing in moment to moment interaction without prescription or assessment. Design, on the other hand, is inherently prescriptive ' therefore the relationship between praxis and design needs to be a symbiotic one.

The analysis of collaborative learning
p 11 ' The aspect of collaborative learning that is perhaps hardest to understand in detail is what may be called " practices of meaning - making in the context of joint activity " inter subjectivity learning (Suthers, 2005) or group cognition (Stahl, 2006) 'This is learning that is not merely accomplished interactionally, but is actually constituted of the interactions between participants'

Most research use codes and categories

'the knowledge building that takes place within small groups becomes "internalised by their members as individual learning and externalised in their communities as certifiable knowledge"' Stahl (2006)
The analysis of computer support
p 12 'Computer support for inter subjective meaning making  is what makes CSCL unique' ......'Design should leverage the unique opportunities provided by technology rather than replicate support for learning that could be done through other means' .......'We should explore    the potential of adaptive media as an influence on the course of subjective processes, and take advantage of its ability to prompt, analyse and selectively respond

The multidisciplinarity of CSCL
Hence the different methodologies
Quant
Experimentally based studies based in controlled factors  p13 ' do not directly analyse the accomplishment of inter subjective learning'
QualCrosby
'The grounded approach is data driven, seeking to discover patterns in the data rather than imposing theoretical categories. The analysis is often micro-analytical, examining brief episodes in great detail' '
KRo but then misses the evolving nature

Suggestion
Use data from qual to inform  quant and then quant to focus the detail work of qual ie an iterative approach.   A quisitive approach (Goldman, Crisby, &  Shea, 2004) p 14 ' a purely data driven approach that dives theory, but never applies it, won't be adequate....... 'Having identified where successful methods were not applied , we then examine the situation to determine what contingency was missing or responsible
