Specifications of the Learning Analytics, Scaffolding Services, and Add-on Services – initial

Résumé 0

This deliverable describes the initial version of the specifications of learninganalytics, scaffolding, and add-on services of Go-Lab. All these services provideadditional functionality to teachers, students and lab owners using the Go-Labportal (see D5.2). This deliverable consists of two major parts: (i) the learninganalytics and scaffolding services and (ii) the add-on services.Learning analytics aims to collect and analyse user activities to make learningand learning environments more effective and efficient. The Go-Lab learninganalytics services provide means to track user activities and analyse thistracked data. This provides the foundation for guidance mechanisms for studentsthrough scaffolding, as well as intelligent decision support for teachersand lab owners. More specifically, the learning analytics services provide supportfor recommendations, intelligent feedback for students, and analytical reportsthat help to design better inquiry based learning scenarios and spaces.This deliverable describes the architecture of the learning analytics services indetail. Furthermore, it explains how this service integrates with the Go-Lab portaland a mechanism that enables privacy of the tracked data controlled by theteacher. We regard the learning analytics service as an enabler of scaffoldingapplications and thus the learning analytics services and its feedback looptogether provide the scaffolding services.The add-on services consist of the bartering platform and the lab booking systemto support Go-Lab Portal in different aspects.The bartering platform offers teachers peer assistance through a tutor socialplatform for expertise sharing related to online labs and inquiry learning spaces.Teachers are motivated to help other teachers and share their skills and knowledgeabout online labs on the bartering platform. Furthermore, the barteringplatform also attempts to make the Go-Lab Portal sustainable and usable bymany schools through active interactions among teacher communities and acredit system, ranging from social rating to payment mechanisms.Since remote labs can only be used by a limited number of users at the sametime, the Go-Lab Portal needs services to arrange which users can use a lab ata given time. Therefore, a Go-Lab calendar-based booking system is offered tomanage remote lab booking tasks. In the booking system three Go-Lab bookingschemes are specified for use by remote labs in order to get Go-Lab as well asexternal remote labs ready for Go-Lab users’ use.In this document usage scenarios, requirements and initial component specifi-cations are described and contextualised with existing research.The specifications in this deliverable will be updated and finalised in D4.6 (M33).Furthermore, a first version of the implemented prototypes will be delivered in D4.4 (M24) and the final implementation will be described in D4.8 (M36). Asa preview for D4.4, Appendix B briefly describes the implementation efforts,achieved up till M18.
