Development of Web-Based Instruction for Review on Measures of central tendency for Vocational certificate student

Abstract

The purposes of this research were to measure the development of Web-Based instruction (WBI) for review central tendency in computer applications to statistics subject and to make a comparison of learning achievements pretest and posttest with WBI for review on measures of central tendency in computer application to statistical subject. The sample groups used in this research were 3rd year Vocational Certificate students in Samutprakarn Technical College and registered to study computer application for statistical subject in the second semester academic Year 2013, 63 students were divided into two sub-groups, the first group were 30 students will find the performance of lessons and second group comprised 33 students will compare academic achievement. Both groups selected by cluster random sampling. Tools for the research were consisted, the quality evaluation form of WBI Lesson and achievement test of learning with difficulty level ranging from 0.35 to 0.75, the discrimination level from 0.20 to 0.60 and the Reliability levels 0.82. The data was analyzed by mean, standard deviation and t-test for dependent sample. The result of this study were 1) the quality of WBI Lesson was at a good level ( = 4.33) for lesson contents and good level ( = 4.47) for media production 2) the efficiency of WBI Lesson was E₁/E₂ was 80.22/82.33 and 3). Achievement of learning after using of WBI Lesson was statistical significant higher than before learning at 0.05 level.
