초록
In this research, to examine the effectiveness of the developed microcomputer-based experiment that helped to overcome the problems of 'photosynthetic rate by light intensity' experiments were applied. The study targeted 158 10th graders who were divided into the experimental and the control groups. The experiments were conducted using both the improved microcomputer-based experiment method and the existing experiment method. The improved microcomputer-based experiment showed a statistically significant difference from the existing methods in terms of the accuracy of the experimental results, and the ease with which data analysis and data transformation could be performed by the students (p<.05). Further, it shortens the experiment time. Improved microcomputer-based experiment would expected to be a solution for the problems with the existing experiments on photosynthetic rate by light intensity.
