The Development of Web-Based Instruction of the Effect of Aerodynamics on Vehicle Developed using Google Site

Abstract

This research objectives were 1) to develop the web-based instruction of Aerodynamics effect on ground vehicle developed using Google Site 2) to compare the compare the pre-test and post-test score and to evaluate the satisfaction of students learned via the developed web-based instruction. The target groups of the research were the 15 senior students major in Automotive Engineering of College of Industrial Technology, King Mongkut’s University of Technology North Bangkok who registered in Aerodynamics subject in the academic year 2020 obtained through simple random sampling. The research tools were 1) web-based instruction of Aerodynamics effect on ground vehicle developed using Google Site 2) pre-test and post-test examination 3) Index of item objective congruence between topics and contents evaluation form and 4) the satisfaction questionnaire for web-based instruction. The statistics used in the research were mean, standard deviation, effectiveness index and t-test.

The results showed that the effectiveness index (E.I.) was 0.82 and the posttest score higher than pre-test score at .01 level of significance. Moreover, the satisfaction of the students were at very high level.
