Ability for collaboration is an important skill in many modern professions. Students should master these skills to be able to participate in project work during study, as well as to work in different groups in the workplace (project groups and communities). An important issue in collaborative work is assessment of individual’s contribution. We will present methodology for qualitative evaluation of individual’s contribution in collaborative learning process supported by Wikis and Google Docs. Wikis provide an environment for collaborative writing and enable easy monitoring of students’ activities, such as frequency of editing and amount of published text. Google Docs is a Web-based application in which documents and spreadsheets can be created, edited and stored online. Google Docs could also be used in collaborative work in which multiple authors work together in real time. We will present collaborative learning activities based on editing of Wikis or Google Docs followed by collaborative and peer assessment. Peer assessment is learning activity where students consider and specify the level, value or quality of a product or performance of other people in similar situation, usually student within a given class. Peer assessment is an important activity in collaborative learning. Students will be divided into groups. Each group will consist of 3-4 students. Groups will select project topics regarding to the interest of the members from Videlectures.net or any other portal with scientific or educational video content. The assessment of collaborative work will be supported by Moodle workshop.
