Abstract

Objectives The purpose of this study is to develop blended learning instruction materials for ‘Detailed circuit diagram drawing’ section using Google Classroom in the NCS-based home appliance hardware development subject, and to investigate the effect on the academic achievement of specialized high school students. Methods In this study, the development direction and learning goals of class materials were set through the analysis of curriculum, job duties, and learners, and a plan for using Google Classroom was devised. Instruction materials that can be applied to specialized high school practical classes were developed, Based on the NCS learning module, this class material presented practical information, relational knowledge, design drawings, and self-checklist, and was developed to enable learners to learn by level and self-directed learning. In this study, academic achievement was evaluated by applying the heterogeneous control group after test to two classes of technical high schools. Results As a result of analyzing the effect of the instructional materials developed in this study on academic achievement, there was a significant improvement in academic achievement only in the subgroup in the cognitive domain. On the other hand, in the psychodynamic domain, the academic achievement of the median and subgroups improved, and in the affective domain, there was a significant effect on the students in the middle group. In all areas of academic achievement, there was no significant effect for the students in the upper group. Conclusions The blended learning instructional material developed in this study ‘Create a detailed circuit diagram’ is more effective for the middle-class and lower-class students in terms of academic achievement compared to the traditional instruction-oriented classes.
