model was designed as the experiential learning class strategy based on the problem solving approach. Next, an experience activity task on making 'temperature difference generators' and 'electric refrigerators',that can pursue the understanding of renewable energy and energy conversion at the same time and to be applied to real life, was developed. Also, a teaching-learning process consisting of 8... based on the problem solving approach. Next, an experience activity task on making temperature difference generators and electric refrigerators , that can pursue the understanding of renewable energy and energy conversion at the same time and to be applied to real life, was developed. Also, a teaching-learning process consisting of 8 classes, teacher study materials and student study materials were developed. Finally, the validity of these outcomes was verified by the related experts of 7... -
