Abstract: This study attempted to compare students' abilities achieved from leaming related phenomena and principles of three phases induction motor. Two teaching methods: a conventional and a problem-based on the same content were differently delivered to two groups of students. The researcher believed that the prablem- based instruction would yield better results than the conventional one. Instruments used in the study included two teaching styles, tests measuring learning achievement and problem-solving abilities. Observation sheet monitoring learning activities was also provided. Working operation and working principle of induction motor was used as instruction content. They were rotating magnetic field, voltage, current and mechanical power induced in the machine rotor. Content analysis were performed to find md to rearrange major teaching element to suit each instructional style. The problem-based teaching contents were so arranged that all learning elements were clustered around the problem in a related spiral pattern. The conventional teaching content, 6n the other hand, were arranged according to their cause and effect phenomena. A test-set measuring learning achievement and problem-solving abilities was developed. Learning achievement test items were prepared basing Bloom Taxonomy and test specification. Problem-solving test items focussing on hypothesis setting and verifying were adapted from MEQ Test. All teaching material including tests were unanimously approved by experts. Eighty members of third year students from Petchaburl technical college were randomly selected for the study. Forty of them were assigned as a control group learning with a conventional teaching. Another forty of students assigned as an experimental group worked with problem using related rules and principle. It was founded from the test scores that experimental group student gained higher scores than students from the control group in comprehension, application, and problem-solving. Statistical analysis using T test showed a significant difference of 0.01. During the experiment, however, experimental group students showed more enthusiasm in performing the task than students in the control group.
