Development of Web-based Instruction of Data Communications for Computer Network Tenth Grade Students of Krathumbaen Wisetsamutthakhun School

Abstract

The objectives of this study were to develop, examine quality and efficiency of web-based instruction (WBI) on Data Communication for Computer Network for Tenth Grade Students and to compare learning achievement of the students before and after learning with the instruction. The sample of the study comprised 37 Tenth Grade Students at Krathumbaen Wisetsamutthakhun School in the academic year 2/2014, selected by Cluster Random Sampling method. The research instrument included a web-based instruction on Data Communication for Computer Network, a WBI quality assessment form and a learning achievement test on Data Communication for Computer Network with Difficulty Index = 0.38-0.78, Discrimination = 0.20-0.75 and Reliability = 0.81. The data were analyzed by using arithmetic mean (), standard deviation (S), and paired t-test for dependent sample.

The results showed that the overall quality of the instruction was at a high level (= 4.45 and S = 0.26). In particular, the content quality (= 4.42 and S = 0.28) and the media production quality (= 4.48 and S = 0.23) were at a high level, with the efficiency E₁/E₂ = 81.49/83.51. Learning achievement of the students was found to increase with significantly higher post-test scores when compared to the pre-test scores at 0.05.
