Complementing approaches include lists of concepts and conceptual Vocabularies, Conceptual r ela ti on s hi p s , colla b or a tor r oles , g en er a ti on of con cep t m a p s f r om the hy p er li n k n etwor k Networks and Wikipedia of Wikipedia, parallel rankings based on the statistics of the articles, branching structures and temporal versions of the Linkage articles. Approaches extend to wiki environments for editing concept maps, covering the perspectives of the learner, the context and the objective, exploring the Lauri Lahti shortest hyperlink chains between corresponding Wikipedia articles and recommending routings with a tailored variation and repetition of spaced learning and visualizations. Cumulatively explored conceptual networks, recall effects and language ability levels are contrasted with a review about measures of human learning process and representation of knowledge. 9HSTFMG*agbgde+ 9HSTFMG*agbgde+ ISBN 978-952-60-6163-4 (printed) BUSINESS + ISBN 978-952-60-6164-1 (pdf) ECONOMY ISSN-L 1799-4934 ISSN 1799-4934 (printed) ART + ISSN 1799-4942 (pdf) DESIGN + ARCHITECTURE Aalto Un iversity Aalto University School of Science SCIENCE + Department of Computer Science TECHNOLOGY www.aalto.fi CROSSOVER DOCTORAL DOCTORAL DISSERTATIONS DISSERTATIONS Aa lto Un iver sity pu blica tion ser ies DOCTORAL DISSERTATIONS 48 /2015 Computer-Assisted Learning Based on Cumulative Vocabularies, Conceptual Networks and Wikipedia Linkage Lau ri Lahti A doctor a l disser ta tion com pleted for the degr ee of Doctor of Scien ce (Techn ology) to be defen ded, with the per m ission of the Aa lto Un iver sity School of Scien ce, a t a pu blic exa m in a tion held a t the lectu r e ha ll T2 of the Depa r tm en t of Com pu ter Scien ce on 10 Apr il 2015 a t n oon .

Motivated by previous research identifying possibly similar scale-free small-world properties in Wikipedia online encyclopedia, social networks and human brain networks, we suggest that collaboratively generated knowledge structures of Wikipedia can be used to support learning. After reviewing background of computer-assisted and collaborative network- based learning we introduce using lists of concepts and conceptual relationships generated by students and comparison through rankings. We propose supporting collaborator roles in a collaborative learning environment relying on text-based discussion chains illustrated cumulatively as concept maps. Next, we propose guided generation of concept maps from the hyperlink network of Wikipedia. Then, we propose generating personalized learning paths from Wikipedia by following hyperlinks between articles based on various rankings of the s ta ti s ti cs of the a r ti cles .
