Purpose of the study
This study proposes a conceptual e-learning assessment model, hexagonal eLearning
Assessment model (HELAM) suggesting a multi-dimensional approach for LMS evaluation.

In this study, a survey instrument based on HELAM used and applied to 84 learners. This sample consists of students at both undergraduate and graduate levels who are users of a web-based learning management system, U-Link, at Brunel University, UK. The survey instrument consist of
Six dimensions: (1) system quality, (2) service quality, (3) content quality, (4) learner perspective, (5) instructor attitudes, and (6) supportive issues in addition to the demographic information and overall view.


The study evaluates e-learning systems features such as:

1) Interface
Statements examples:
31. U-Links graphical user interface is suitable for e-learning systems.


2) Navigation
Statements examples:
32. The program directions and navigations are clear.
36. Navigation is very easy on U-Link.
38. In the U-Link system I can easily navigate where I want.


3) Interactivity
Statements examples:
33. U-Link supports interactivity between learners and system by chat, forums, discussions, etc.


4) Accessibility
Statements examples:
39. U-Link is easily accessible via Internet.
42. U-Link is accessible 7 days 24 h.


5) Support
Statements examples:
35. When I counter an error in the system, I can get immediate feedback by e-mail and telephone.
41. Help option is available on the system.
