The Development of Web-Based Instruction of Mathematics 1 on Ratio and Percentage for Students Certificate in Vocation Education Level 1
The purposes of this research were: 1) to develop the web-based instruction (WBI) on Mathematics 1 topic of Ratio and Percentage for students certificate in vocation education level 1 with a required standard efficiency criterion of 80/80, 2) to compare learning achievement before and after with learning the developed WBI, 3) to study the students satisfaction toward learning by the web-based instruction on ratio and percentage by the web-based instruction. The population of this research were 227 certificate of vocation education level 1 students attending Thatphanom college of Nakhon Phanom University, who enrolled in the first semester in an academic year 2013. The samples were 30certificate of vocation education level lin accounting students selected by cluster random sampling. The instruments used in this study were: web-based instruction on Mathematics 1 topic of Ratio and Percentage, 30-iterm achievement test with the difficulty value between 0.47-0.83, the discrimination value between 0.30-0.89, the reliability of 0.98 the index of item objective congruence (IOC) of 1.00 and 19-iterm 5 level satisfaction questionnaires. The statistics employed in data analysis were validity, difficulty, discrimination, reliability, percentage, mean, standard deviation, efficiency and t-test (Dependent samples). The results of this research shown that: 1) The efficiency of web- based instruction on Mathematics 1 topic of Ratio and Percentage for students certificate in vocation education level 1 were 89.43/93.43, 2) The students learning achievement after the learning using the web-based instruction on Mathematics 1 topic of Ratio and Percentage for students certificate in vocation education level 1 was significantly higher than before using it at .01 level. 3) Satisfaction of student after using the web-based instruction on Mathematics 1 topic of Ratio and Percentage for students certificate in vocation education level 1 students was at highest level ( = 4.55, S.D. = 0.50)
