A Development of Web-Based Instruction for Using Synectics Teaching Process on Creativity of Computer Graphics for Grade 12 Students

Abstract

The purpose of this research were to develop the Web-Based Instruction using synectics teaching process on creativity of computer graphics, to evaluate quality and efficiency of the lesson and to compare pre-test and post-test learning achievement of the students after the experiment. The samples in this study were 40 grade 12 students at Chamnansamakkhiwittaya School in the second semester of the academic year 2014. They were assigned by cluster random sampling. The research instruments were the Web-Based Instruction lesson, the Web-Based Instruction evaluative questionnaire, and the Web-Based Instruction achievement test with the Difficulty = 0.50-0.77, Discrimnination = 0.20-0.70 and Reliability = 0.84. The statistics used in the analysis were mean ( ), standard deviation (S), and t-test for Dependent Samples.

The result showed that the quality of Web-Based Instruction was at an excellent level ( = 4.53, S = 0.07) in regard to the lesson content and also the media production (  = 4.51, S = 0.40). The efficiency of Web-Based Instruction (E₁/E₂) was 81.59/81.27 respectively, which was based on the criteria that it should not be less than 80/80 and Comparing the overall learning achievement of Web-Based Instruction revealed post-test achievement to be higher than that of pre-test at 0.05 significant level.
