The Study of Creative Problem Solving for Grade 2 students on the title the number greater than 1000 by using Open Approach and Lesson Study

Abstract

The objectives of this research were 1) to analyze students’ creative problem solving ideas 2) to study the thinking result of creative problem solving by at least 75 percentage of students pass 75 percentage of the total score of creative problem solving test 3) to study learning achievement by at least 75 percentage of students pass 75 percentage of the total score of achievement test. Research target group consisted of 38 grade 2/1 students studying in the second semester of the Academic Year 2019 at Demonstration School of Khon Kaen University (Modindang), Khon Kaen province. Research methodology was Quasi-experimental designs. The instruments used for gathering data were 1) Mathematical lesson plans on the title the number greater than 1000 2) creative problem solving test and 3) learning achievement test. Data was analyzed from field note, video recording, teaching recording, photo taking, students’work, creative problem solving result and learning achievement result.

The research finding result found that

1. Students shown various creative problem solving ideas from participating Open Approach class which was emphasized students to solve a problem from open-ended problem situation. They could find many proper ways to solve a problem. They even could explain step by step how to think and give the reasons. They could figure out meaningfully their answer as a symbol. Furturemore, students showed fully four components of creative problem solving ideas as these following 1) Fluency; students could think about the ways how to solve problems more than two ways and several answers with a limited time. The result of average quality score was 3.6 which meant very good level. 2) Originality; students displayed suitably new ideas how to solve problems which were differ from others. The result of average quality score was 3.6 which meant very good level. 3) Flexible; students were able to adapt an apparent thing that they have got as a tool to compensate the limited condition in order to they could find varied ways to solve problems. The result of average quality score was 3.8 which meant very good level. 4) Elaboration; students could clarify detail and expand completely their ideas to unravel the questions. Moreover, they could present explicitly their ideas in their simple ways. The result of average quality score was 3.9 which mean very good level.
2. The result of creative problem solving test was found that there were 31 students as 81.58 percentage of 38 students who reached the score criterion. The result was higher than expected criterion which was said 75 percentage of students pass 75 percentage of the total score.

       3. The result of learning achievement test was found that there were 35 students as 92.11 percentage of 38 students who reached the score criterion. The result was higher than expected criterion which was said 75 percentage of students pass 75 percentage of the total score.
