The Development of Problem-Solving Ability of Grade 9 Students Using Storyline Learning Management in the Topic of Ecosystem

Abstract

           The purpose of this research were to (1) compare the problem-solving ability of grade 9 students before and after using storyline learning management in the topic of ecosystem (2) compare the problem-solving ability of grade 9 students after using storyline learning management in the topic of ecosystem compared with 70% of the criteria, and (3) evaluate the development of problem-solving ability of grade 9 students after using storyline learning management in the topic of ecosystem. The sample used in this research was 33 grade 9 students in Pathum Thani Province during the second semester of the academic year 2020. The instruments used in this research consisted of 1) Lesson Plans, and 2) the Problem-Solving Ability Test. The one group pretest-posttest design was used in this research. The data were analyzed using means, standard deviation, relative gain score, and  t – test for dependent sample. 
          Research findings were as follows: (1) Students’ problem-solving ability after using storyline learning management in the topic of ecosystem was significantly higher than before studying at the .05 level. (2) The score of students’ problem-solving ability after using storyline learning management in the topic of ecosystem was significantly higher than the criteria 70% at the .05 level, and (3) The results of evaluating the development of students’ problem-solving ability after using storyline learning management in the topic of ecosystem with relative gain scores, overall, the average was in the middle level.
