Collaborative E-Learning through Open Social Student Modeling and Progressive Zoom Navigation

Abstract

Abstract-Students usually do not study individually; instead, they tend to study collaboratively. The "power of known peers" can be embraced to provide implicit navigation support for collaborative social e-learning environments. In this paper, we present a novel approach to collaborative e-learning through open social student modeling with Progressive Zoom navigation support. Progressive Zoom is a Google-Maps paradigm which seeks to address information overload issues. It enables students to zoom in or out in a multi-layer fashion, so students can reflect on their individual and peer progress based on the knowledge and pedagogical context. In our initial survey, all students were satisfied with the navigation interface and would recommend the interface to their classmates.

Learners Thrive Using Multifaceted Open Social Learner Modeling

“…However, it cannot fit larger classes that generate too many cells. ProgressiveZoom [6] is built upon the Google-Maps paradigm, seeking to address information overload issues, by enabling learners to zoom in or out in a multi-layer fashion. However, it has limited ability to control comparisons between learners.…”

“…To diminish the impact of isolation in e-learning, more recent studies propose to allow learners to observe peer models and group models [5]. This new social OLM approach, called Open Social Learner Modeling (OSLM), benefits from both metacognitive and social aspects of learning [6].…”

Multifaceted Open Social Learner Modelling

“…However, QuizMap cannot fit larger classes that generate too many cells on the TreeMap, causing it to become too crowded (information overload). ProgressiveZoom [12] is built upon the Google-Maps paradigm, seeking to address information overload issues, by enabling learners to zoom in or out in a multilayer fashion. However, it has limited ability to control comparisons between learners.…”

“…Yet, the student models explored in earlier projects were relatively simple and typically presented in one-shot that eliminated a need to explore the model in detail. In contrast, our work focuses on reasonably complex concept-based user models with hundreds of concepts and studies a progressive zoom [10] approach to explore these models.…”
