Abstract:
The objectives of this research were to develop a pentomino puzzle game to enhancing spatial ability in lower secondary school students and to apply the developed program to sixty lower secondary school students at Noenmahad School, Chanthaburi province. The research design pattern was an experimental design as 2-Factor Pretest-Posttest Control Group Design. The research instruments were a pentomino puzzle game program with the computer game, pentomino puzzle game Program with the broad game, and spatial ability test (Newton, 2009). The average spatial ability scores were used as dependent variable. The t-test was used to analyze the data.
The results were as follow, 1) A pentomino puzzle program was suitable for increasing the spatial ability in lower secondary school students. 2) The average scores of spatial ability in the experimental group after using a pentomino puzzle program with the computer game were significantly higher than before using a program (p < .01) 3) The average scores of spatial ability in the experimental group after using a pentomino puzzle program with the broad game were significantly higher than before using a program (p < .01) 4) The average scores of spatial ability in the experimental group after using a pentomino puzzle program with the computer game were significantly higher than the experimental group receiving a pentomino puzzle program with the board game (p < .05). These findings demonstrated that the pentomino puzzle program with the computer game can increase the spatial ability. Therefore, this approach is an alternative program for brain training for lower secondary school students.
