Addictive links: the motivational value of adaptive link annotation

Peter Brusilovsky, Sergey Sosnovsky, Michael Yudelson
2009 New Review of Hypermedia and Multimedia  
In this paper, we present our exploration of a less known effect of adaptive annotation, its ability to significantly increase student motivation to work with non-mandatory educational content.  ...  Empirical studies of adaptive annotation in the educational context have demonstrated that it can help students to acquire knowledge faster, improve learning outcomes, reduce navigational overhead, and  ...  Fig. 2 . 2 The interface of QuizGuide provides adaptive access to a specific kind of educational content: interactive programming examples (about 70 examples are accessible through NavEx).  ...

The role of community feedback in the student example authoring process: An evaluation of AnnotEx

I-Han Hsiao, Peter Brusilovsky
2011 British Journal of Educational Technology  
This approach was implemented in AnnotEx (Example Annotator) system, which allows students to annotate computer programming examples with line-by-line explanations and review annotations produced by ther  ...  Multiple code examples, ranging from small code snippets to complete programs, can be found in any programming textbook and are frequently also provided on an attached CD or a web site supporting the textbook  ...  WebEx provided Web-based interactive access to examples enhanced with line-by-line comments, allowing students to browse the comments at their own pace and chosen sequence (Figure 1 ).  ...

The Impact of Social Performance Visualization on Students

Mohammad Hassan Falakmasir, I-Han Hsiao, Luca Mazzola, Nancy Grant, Peter Brusilovsky
2012 2012 IEEE 12th International Conference on Advanced Learning Technologies  
The other stream of research on Open Student Modeling (OSM) attempts to visualize the state of individual student's knowledge and present the visualization directly to the student.  ...  The results of the study shows that: 1) the students are likely to use the social visualization tool during the whole semester to monitor their progress in comparison with their peers; 2) the visualization  ...  ACKNOWLEDGMENT The authors thank Intelligent System Program, School of Arts & Sciences at University of Pittsburgh for partially supporting this research.  ...

KnowledgeTree

Peter Brusilovsky
2004 Proceedings of the 13th international World Wide Web conference on Alternate track papers & posters - WWW Alt. '04  
The goal of KnowledgeTree is to bridge the gap between the currently popular approach to Web-based education, which is centered on learning management systems vs. the powerful but underused technologies  ...  This integrative architecture attempts to address both the component-based assembly of adaptive systems and teacher-level reusability.  ...  To provide adaptive access to WebEx examples, we use a value-adding service NavEx. NavEx is also a domaindependent service focused on teaching programming.  ...

Recommendation and Students' Authoring in Repositories of Learning Objects: A Case-Based Reasoning Approach

Mercedes Gomez-Albarran, Guillermo Jimenez-Diaz
2009 International Journal of Emerging Technologies in Learning (iJET)  
This approach is going to be applied to a repository with more than 200 programming examples written in different programming languages.  ...  More recently, NavEx [20] , an evolution of the webbased tool WebEx [25] for exploring annotated program examples developed using the C programming language, Educational repositories that incorporate  ...  It will also distinguish among examples that are new to the student from those that she has previously accessed, as NavEx does [20] . This could help students to explore the examples retrieved.  ...

Accessing interactive examples with adaptive navigation support

M. Yudelson, P. Brusilovsky, S. Sosnovsky
IEEE International Conference on Advanced Learning Technologies, 2004. Proceedings.  
We introduce the system NavEx that is able to provide adaptive annotation of programming examples without any need of manual indexing.  ...  This paper discusses a need to provide adaptive navigation support for students accessing large numbers of interactive examples in Web-enhanced education.  ...  Our system WebEx [2] attempts to integrate these two approaches to example presentation. WebEx serves interactive explained examples via the Web.  ...
