Abstract:
The study was the experimental research. The purposes of this study were
1) to develop a Web-Base Instruction using 2D Virtual Laboratory (WBI-2DVL) on
Science on the Topic of Force and Pressure, 2) to validate the efficiency of the
developed WBI-2DVL, 3) to compare the learning achievement before and after
using WBI-2DVL, and 4) to survey the students satisfaction. The sampling group,
selected by simple random sampling, was 23 fifth grade students who studied
at Wattritosathep School. The research tools were the developed WBI-2DVL, pretest,
posttest, and summarized test.
The results showed that 1) the efficiency of the developed WBI-2DVL was
84.58/81.95, 2) the learning achievement after using the developed WBI-2DVL was
higher than before using it at statistically significant value of .01, and 3) the student
satisfaction was at good level
