Classroom Practice Using 3DCG Dinosaur Skeleton Teaching Materials and Exploratory Evaluation of Teaching Material Features Using Textual Analysis

Abstract

The purpose of this study is to develop a dinosaur skeleton teaching material that can be easily used in a regular classroom environment and to verify its educational evaluation. The teaching materials developed in this study have the following two features. The first is that AR display is available, enabling users to observe dinosaurs at actual size. Second, the name of each part of the pelvis, which is important when observing a dinosaur skeleton, is displayed. In order to verify the educational effects of the developed teaching materials, we conducted a practical class. In the class, students were asked to describe the characteristics of the pelvis of Triceratops and Tyrannosaurus, respectively. The students were also asked to describe what they found interesting. The textual analysis of these descriptions suggested the following two points. First, some students noticed the distinctive shape of the pubic bone by observing the 3DCG dinosaur skeletons even without prior explanation. The second point is that students enjoyed observing the actual size of the dinosaurs using the 3DCG dinosaur skeletons.
