This research is an experimental research. The purposes of this research were 1) to
develop a Web-based Instruction on the Information Technology and Communication
Course for the 10th Grade Students of Benchamamaharat School 2) to evaluate the

the 10th grade of the Benchamamaharat School. They were selected by purposive

questionnaire, Tests (pretest/posttest). The data obtained from the experts and students
were collected and analyzed using the statistics as follows :The statistic formula used in
this study are mean (average) and the standard deviation (S.D.) , Meguigans formula used
to evaluate the efficiency of the WBI , and finally, dependent t-test used to compare the
students learning achievement (pretest and posttest.)
The results of this research showed that the efficiency of WBI was 1.14 based on
Meguigans Standard. The mean of posttest was significantly higher than pretest, at the
statistic level .05. Finally, the students satisfaction was at the level of high.
