Linda started her presentation by laying out the theoretical framework (CSCL, Language Learning Competence, affordances in technology) for her study and quickly walking people through the main ideas and functionalities of wikis. The empirical setting of the study is higher education with 54 IT engineering students in 25 groups during a 7 week study course.
The F2F course is supported by a VLE, web based materials (texts, newspaper articles) and the wiki. Students work with texts learning about styles of language, formal and informal texts, argumentation and critical writing. The writing is done in collaboration with the other students (on assignments like "write about the pros and cons of wikipedia as a reference). The students uploaded their ideas in a designated folder on the wiki where they can expand the texts and ideas further together. The flow of versions is all stored in the same folder. The progression ideas and texts can be easily detected and followed. All groups gave and received feedback from their peer groups in the second assignment. The teacher gave feedback in the first assignment to set an example for the students.
The results show the nature of interaction was very much collaborative and that the nature of the feedback given by the students followed the model set by the teacher. Linda made some comparisons to the study she and colleagues carried out as a pilot to this year's study. In the pilot the use of wiki was more open-ended as in this year's study is was the specified tool to use. This resulted in a more systematic use of the environment but also a more systematic writing process.
Linda do add to my still foggy posting... :)
