Development of Learning Activities that Promote Spatial Sense “Two-Dimensional and Three-Dimensional Geometric Figures” of Mathayomsuksa 1 Students

Abstract

The purpose of this research were to (1) develop learning activities that promote spatial awareness of two-dimensional and three-dimensional geometric figures for Grade 1 students to be effective according to the criteria 75/75. (2) To study the spatial sense of Grade 1 students. (3) To study the development of spatial sense of Grade 1 students. The sample group were 160 students of Grade 1 obtained from Purposive Sampling. The tools used in the research include organizing learning activities that promote spatial awareness and Spatial Sense Test. The statistics used in the data analysis were percentages, averages, and standard deviations. Task analysis and analytic description were used for data analysis. The quality of the research instrument was 0.43 to 0.70, the classification power was 0.30 to 0.80, and the confidence value was 0.94.

            The results showed that (1) Developing learning management that promotes spatial awareness  can summarize the 6 teaching steps. Each learning management step has an activity sheet. There are appropriate teaching materials and students are allowed to go out and do activities in front of the class. The results of learning management that promotes spatial awareness efficient is 79.71/81.35 that is higher than the set threshold. (2) Students have a high level of spatial awareness in visual classification, 55 people, accounting for 56.90 percent moderate level in spatial relational awareness, 56 people, accounting for 47.06 percent and  a low level in distinguishing images from the background, 88 people, accounting for 23.11 percent (3) Guidelines for Developing Spatial Sense Design teaching and learning to make it easier for students to understand and let students think. Take action to improve students' skills.
