The Development of Transformer Instructional Media for Teaching with 7E Learning Cycle Method

Abstract

The objective of this research is to study the number of coil turns that affect the voltage change. The achievement and educational satisfaction of the Mathayomsuksa 5/1 students who used the instructional media set of the transformers in the 7E learning cycle model. Sampling groups were student in Sainoi Secondary School totally 34 students. The instruments were used in this research consistsed of a demonstration set of transformers. 7E learning cycle model management plan in conjunction with the demonstration set of transformers, pre-pose test of achievement, and the satisfaction with analyzed data by statistics, percentage and normalized gain.

                The research results can be summarized as follows. The number of turns in the coil can affect the voltage according to the theory, Students who studied 7E learning cycle model with the demonstration set of transformers had higher learning achievement than before and enhancing learning equal to 0.67 at the level of medium and the satisfaction of students was at the highest level.
