A Survey on LMS Context Dimensions for Teacher-Oriented Recommender Systems

Abstract

Abstract-In formal education, a majority of e-learning courses is still conducted in a learning management system (LMS). Teachers and authors of educational resources can make use of context-aware recommender systems, which would recommend relevant learning objects to be included in the course. Context data can be obtained, among other sources, from an existing learning environment. This paper describes a two-phase survey of four LMSs -Chamilo, Claroline, Ilias and Moodle -and their characteristics suitable for creating an LMS part of a context model, which would be relevant to implement in recommender systems for this purpose. A sample set of use cases is given, which describes how teachers and content authors could use the system. Based on the survey results, a set of context model dimensions is proposed.

Collaborative Recommender System A Review

“… Hybrid Methods: Combined both above methods. [29], [30], [16], [31] , [32], [33], [34], [20] Model-based methods [35], [36], [37], [12], [22], [18], [17], [38], [39], [15] , [20], [21] Hybrid Methods [40], [36], [19], [41], [42], [43], [44] In collaborative RS in education, model-based method is the most prefered as shiwn in Table II. Among the methods used are Tag-based [40], clustering [18], [22], data mining [17], [12], [39], [28] iterative method [45], Learner"s Role based Multi-Dimensional [21], and 2-Tuple fuzzy linguistic approach [15], [20] [38].…”

“…Examples are recommendation of activity class for multi-label classification [16]. formalize the weighting of the recommendations [36], used of set of context model [30], recommendation of feasible learning goals that covering the learning needs [45], recommendations to courseware authors using association rule mining and collaborative filtering [45], recommendation system according to readers" interest and books properties [35], recommendation of e-learning recommender systems [41], and recommendation to read lessons based on the recommender scores [5]  Ranking -It is presented in the form of ordering list.…”

“… Postgraduate: Student who is denoting of studying undertaken after completing first degree  School student: School student contain primary and secondary student. [29], [41], [36], [17], [21] , [16], [34], [39], [22], [37], [48], [49] Postgraduate [19], [32], [42], [33], [38] , [40] School student [30], [45], [31], [18], [15] B. Learning Object…”

“…The summarization can be discussed as below:  Learning material: Student can use learning material include text and multimedia on all areas in the curriculum. Example of learning material are book [41], [45], slide [30], [22], scheme [16], and audio [32]  Learning activities: are activities that designed by instructor. [41], [30], [22], [45], [16], [32] Learning activities [29], [41], [36], [22], [40], [21], [39], [34], [16], [33], [12], [24], [32], [15] I.…”
