The Development of a Problem-Solving Lesson Plan Applied to an Online Learning in the Electrical Circuit Course

Abstract

               The objectives of this research were 1) to develop a problem-solving learning plan applied to an online learning in the course of electrical circuits; and 2) to examine the efficiency of a problem-solving learning model using research and development methodology. The problem-solving learning model applied to online learning has been evaluated in terms of suitability and congruence by 3 specialists who have taught the electrical circuit course. The research samples were 23 first-year students randomly selected from 83 students in a field of Electrical Engineering and Electronics and Automation Systems Engineering in the faculty of Technical Education at Rajamangala University of Technology Thanyaburi.  The research instruments consisted of five-scale suitability assessment form and satisfaction questionnaires. The data were analyzed using percentage, arithmetic mean, standard deviation, and T-test. The results showed a problem-solving learning model applied to an online learning in the electrical circuit course has been a high suitability ( =  4.19, SD = 0.75); and the efficiency of process (E₁) and efficiency of product (E₂) were 82.83/84.57. In addition, the average scores of the students after the experiment were greater than the average scores before the experiment with statistical significance at 0.05. The average satisfaction scores after the experiment were at the highest level ( = 4.42, SD = 0.68).
