Multimedia Animation Learning on Based-Centered Cubic (BCC) Slip Plane Subject for the Prospective Teacher's Critical Thinking Skills

Abstract

Difficulties of students in engineering material courses are known from the results of preliminary research including those that occur in material related to the micro atomic structure. The difficulty in understanding this material is due to its abstract nature. On the other hand, this material is very important because it precisely determines the material properties. Theoretical learning in the form of verbal symbols is not representative enough to explain the concept of the system as needed so that the possibility is inaccessible by students which impact on the lack of learning experience. This issue has implications for errors in the construction of a whole system of engineering material, both micro-atomic structural systems and material properties and phase change according to their real application. This research is closely related to efforts to improve the quality of learning in engineering material subjects, especially critical thinking skills in the field of based-centered cubic (BCC) Slip Plane. This study aims to determine the increase in the critical thinking ability of prospective teachers using multimedia animation. The research method is a pre-experimental method with a one-group pretest-posttest design. The results showed a significant increase in the critical thinking ability of prospective teachers who use multimedia animation. This happens due to the long-term memory resulting from learning using animated multimedia.
