Abstract

In this research we aim to propose an advanced metric to evaluate the effectiveness of learning objects in order to be reused in new contexts. By the way learning objects reusability is achieving economic benefits from educational technology as it saving time and improving quality, but in case of choosing unsuitable learning object it may be less benefit than creating the learning object from scratch. Actually learning objects reusability can facilitate systems development and adaptation. By surveying the current evaluation metrics, we found that while they cover essential aspects, they enables all reviewers of learning objects to evaluate all criteria without paying attention to their roles in creating the learning object which affect their capability to evaluate specific criteria. Our proposed Approach (LOREM) is evaluating learning objects based on a group of Aspects which measure their level of effectiveness in order to be reused in other contexts. LOREM classifies reviewers into 3 categories; 1. Academic Group: (Subject Expert Matter â€œSMEâ€ and Instructor). 2. Technical Group: (Instructional Designer â€œIDâ€, LO Developer and LO Designer). 3. Students group. The authorization of reviewers in these several categories are differentiated according to reviewer's type, e.g., (Instructor, LO Developer) and their area of expert (their expertise subjects) for academic and students reviewers.

Highlights

The increasing of learning objects reusability popularity became very observable nowadays; it can be evidenced by the large number of learning objects repositories which became available (Falcão de Berredo and Soeiro, 2007)
The proposed metric (LOREM) is a system evaluating learning objects according to some criteria, some of these criteria have been used before in other significant metrics like Learning Object Review Instrument (LORI) and MERLOT metrics while some other criteria we suggest after researching and conducting meetings with professional education specialists
The proposed metric supposed to help educational organizations, trainers, LO developers and any one working in learning objects filed by giving them evaluation to the effectiveness of reusable learning objects to help in the selection of reusable educational materials from repositories on the web and it can be used in a certain organization to evaluate its created learning objects which saved in its repository to be reused afterwards in other contexts

Summary

Introduction

The proposed metric (LOREM) is a system evaluating learning objects according to some criteria, some of these criteria have been used before in other significant metrics like LORI and MERLOT metrics while some other criteria we suggest after researching and conducting meetings with professional education specialists This system enables only registered users to evaluate LO based on their areas of expert as they fill in the registration form. The proposed metric supposed to help educational organizations, trainers, LO developers and any one working in learning objects filed by giving them evaluation to the effectiveness of reusable learning objects to help in the selection of reusable educational materials from repositories on the web and it can be used in a certain organization to evaluate its created learning objects which saved in its repository to be reused afterwards in other contexts
