Diagnostic and remedial learning strategy based on conceptual graphs

Abstract

Numerous scholars have applied conceptual graphs for explanatory purposes. This study devised the 'Remedial-Instruction Decisive path (RID path)' algorithm for diagnosing individual student learning situation. This study focuses on conceptual graphs. According to the concepts learned by students and the weight values of relations among these concepts, this study established the remedial-instruction paths to identify their real missing concepts. This study applies diagnostic and remedial learning strategies to two courses -'Introduction and Implementation of RS-232' and 'Electronic Circuits Laboratory'. By analysing the scores of the midterm and final exams, evaluations of remedial learning yield positive experimental results. Participants who adopt the diagnostic and remedial learning strategy have better academic performance.

An Educational Data Mining Approach to Concept Map Construction for Web based Learning

“…It has been observed that for P-Learning general data mining algorithms like Apriori [34,50], DHP [33,54], SPRT [47] have been used for concept map computation. For C-Learning concept maps have been constructed based on discussion between the learners [57,59,61] and thus EDM techniques have not been used.…”

“…al. [47] suggests two main applications of concept maps. In the first type of applications, students learn a subject and construct concept maps based on it.…”

“…Following Jong's [47] classification on the basis of applications, it has been found that concept mapping technique has mostly been used for collaborative applications. In typical applications, learners have been found to develop their own concept maps based on domain knowledge.…”

“…It was used for diagnosing common misconceptions for a course on Fractions. Jong et al [47] has devised a learning system using Sequential Probability Ratio Test (SPRT) to understand whether a student has learned a concept or not. Their study devised the 'Remedial-Instruction Decisive path (RID path)' algorithm for diagnosing individual student learning situation.…”

Improving the Learning Performance by Providing Intellectual Suggestions

“…As known, to improve students' learning performance, the teacher should give them additional suggestions. However, it is time consuming for him to give personalized suggestions to each student, particularly when there are many students in class [1,16].…”
