Progressor

Overview

A large number of educational resources is now made available on the Web to support both regular classroom learning and online learning. However, the abundance of available content produced at least two problems: how to help students to find the most appropriate resources and how to engage them into using these resources and benefit from them. Personalized and social learning has been suggested as potential ways to address these problems. Progressor attempts to combine the ideas of personalized and social learning to help students find the most relevant resources in a large collection of parameterized self-assessment questions for programming.

Progressor is a collaboration work between University of Jena and University of Pittsburgh. The core research goal of the project is to utilize the success of self-assessment programming language learning tool, QuizJET, with rich-interaction interface derived from IntrospectiveViews and provide a better personalized visual access to programming language problems. The research investigates open social student model; how social guidance affects self-assessment programming language learning; motivational effects on the progress of educational content; privacy and data sharing and so on.

We are excited about what we've learnt from this project, we are now extending our approaches to a larger collection of learning objects for cross content navigation and verify its capability of supporting social visualization for personalized E-Learning, please refer to Progressor+

Features

• Learner Analytics: question attempts, successful rates, overall progress etc.
• Privacy management: requests for accessing peers' models.
• Interactivity: interacting with the content, peers etc. from the visualization; allowing the user to feel in control.
• Identity: captures all the information belonging to the student and displays it in a unique model, allowing easy comparisons.
• Exposure: model thumbnails preview. We found that students had more persistent interactions with the system while they had higher visibilities.
• Guidance: implicit social guidance; (explicit social guidance is under investigation now)
• Recommendation: top 3 performers

Using Progressor

We design the following protocol allows requesting user or group progress in JSON format. The protocol follows REpresentational State Transfer(REST) architecture and is an extension of CUMULATE protocol. It provides the applicability for applying it to other social visualizations, such as Progressor+.
