The impact of LMS usage on cognitive load in a programming course:an evaluation using NASA-TLX

Abstract

In the Learning Management System (LMS), the student's cognitive load affects learning. In this study, the cognitive load of students using LMS in object-oriented programming courses was examined. The research was carried out with 35 students who used LMS to learn a new topic related to the course. After completing the tasks given, the cognitive load levels of students were evaluated using the NASA-TLX scale. Findings were classified according to individual characteristics such as gender, LMS experience, and academic success. The results were interpreted as the presence of moderate cognitive load. It was also observed that cognitive load differed depending on gender, LMS experience, and academic success level. The study emphasises that individual differences should be considered in LMS design. In addition, the concept of cognitive load in digital education environments has become increasingly important for understanding the relationship between students and various influencing factors. It is suggested that cognitive load can be reduced in LMS with future improvements.
