Development and evaluation of teaching materials in "science and technology and human beings" using a Peltier device

Abstract

In this study, we developed and practiced teaching materials that can lead to learning that involves experiments and observations in "science and technology and human beings" as the last unit of the first field of lower secondary school.lessons. The teaching materials that we have developed include Peltier device, and. A we have developed a three-wheeled self-made vehicle that is run by Peltier cells, which are constituted by safe and inexpensive materials, powered by electric energy generated by Peltier device to allow children to easily make experiments and observations. As a result of such lessons practiced with these teaching materials, children conducted learning activities to apply various ideas to Peltier device and the three-wheeled vehicle to make the vehicle run faster, and it has been clarified that children learn to recognize the necessity to promote harmony between their living environment and scientific technology through such activities.
