Clustering Analysis for Automatic Certification of LMS Strategies in a University Virtual Campus

Abstract

In recent years, the use of Learning Management Systems (LMS) has grown considerably. This has had a strong effect on the learning process, particularly in higher education. Most universities incorporate LMS as a complement to face-to-face classes in order to improve the student learning process. However, not all teachers use LMS in the same way and universities lack the tools to measure and quantify their use effectively. This study proposes a method to automatically classify and certify teacher competence in LMS from the LMS data. Objective knowledge of actual LMS use will help the university and its faculty to make strategic decisions. The information produced will be used to support teachers and institutions in the classification and design of courses by showing the different LMS usage patterns of teachers and students. In this study, we processed the structure of 3,303 courses and two million interactive events to obtain a classification model based on LMS usage patterns in blended learning. Three clustering methods were compared to find which one was best suited to our problem. The resulting model is clearly related to different course archetypes that can be used to describe the actual use of LMS. We also performed analyses of prediction accuracy and of course typologies across course attributes (academic disciplines and level and academic performance indicators). The results of this study will be used as the basis for an automatic expert system that automatically certifies teacher competence in LMS as evidenced in each course.INDEX TERMS Clustering methods, data mining, learning systems, machine learning.

Guiding the Students in High School by Using Machine Learning

“…In this study, the importance of students' opinions was the main tool to judge it. This may weaken the results of the research because the variety and the differences in the opinions may lead to many useful results [30]. The use of artificial intelligence and machine learning techniques in the field of education is very important and common as many researchers have been ready to employ artificial intelligence techniques to support the education system and increase academic success rates by building systems to assess students and predict their academic performance using automated learning algorithms ( [17], [18]), and many researches have achieved high accuracy and one of the researches was based on (Fuzzy Logic model) using (genetic algorithm) with a high accuracy rate of 84.52% [27].…”

“…In all previous research, most data were collected from student information systems. In contrast to previous research, some studies were concerned with making use of machine learning algorithms to evaluate teachers' performance and improve their performance ( [29], [30]).…”

Analyzing and Interpreting Students’ Self-regulated Learning Patterns Combining Time-series Feature Extraction, Segmentation, and Clustering

“…Foster online interactions by encouraging students to ask questions (Regueras et al, 2019). Cultivate critical thinking in online interactions by checking students’ prior knowledge and understanding frequently.Guide online discussions with assorted smaller discussion topics (Zulkifli et al, 2020).…”

Difficulty-Based SPOC Video Clustering Using Video-Watching Data

“…Clustering analysis, such as the clustering of learners [5], [6] and learning resources [7], [8], is a hot topic in the EDM area. Learning resources clustering techniques help find the relation between the resources for learners and teachers [9], [10].…”
