A DEVELOPMENT OF INSTRUCTIONAL PACKAGE OF MECHANICAL WITH DESIGN PROCESS TO ENHANCE SYSTEM THINKING OF ELEMENTARY SCHOOL STUDENTS

Abstract

The purposes of this research were 1) to instructional package of mechanical with design process to enhance system thinking of elementary school students and 2) to study the pre-test and post-test scores after learning with the package. The sample included 24 Prathomsuksa 6 students at Prasartvidhyanonthaburi School in academic year 2018. The research instruments involved instructional package of mechanical, achievement test, and questionnaire. Data were statistically analyzed in mean, standard deviation, efficiency, and t-test.

The findings revealed as follows

1) instructional package of mechanical with design process to enhance system thinking of elementary school students had the efficiency level of 81.35/ 82.94, which was higher than the preset criteria 80/80.

2) the post-test mean score after learning with the package were significantly higher than the pre-test mean score at the .05 level.
