Abstract

       The study aimed at 1) developing the lesson plans on The Earth and World Changes by manipulating 7E Learning Activities Inquiry Instructional Methods for Mathayomsuksa 2 students with an efficiency of 80/80. 2) comparing the students' learning achievement between before and after learning in Earth and World Changes module through using 7E Learning Activities Inquiry Instructional Methods for Mathayomsuksa 2 students. 3) finding out Scientific mind of Mathayomsuksa 2 students toward 7E Learning Activities Inquiry Instructional Methods.

       The samples in this study were 13 Mathayomsuksa 2 students in the second semester of the academic year 2019 of Bankhangyaw School, they were selected by Simple random sampling technique. The research instruments consisted of 1) The 5 lesson plans by using 7E Learning Activities Inquiry Instructional Methods. 2) a 30 - item with 4 multiple-choice achievement test on Earth and World Changes module, the degree of difficulty between 0.31 – 0.75, the discrimination power between 0.25 – 0.63, and the reliability coefficient of 0.83 and 3) a 35 - item of 5-rating scale satisfaction questionnaire. The statistics used for analyzing the collected data were percentage, mean, standard deviation and t-test Dependent Sample. The results were as follows:

       1) The efficiency of the developed lesson plans on The Earth and World Changes module by using 7E Learning Activities Inquiry Instructional Methods for Mathayomsuksa 2 students at 81.85/80.26, which was higher than the criteria set of 80/80.

       2) The students' learning achievement after learning with the developed lesson plans on The Earth and World Changes module by using 7E Learning Activities Inquiry Instructional Methods for Mathayomsuksa 2 students was higher than before with the statistically significant at the level of .05

       3) The students' satisfaction toward using 7E Learning Activities Inquiry Instructional Methods was at the highest level.
