Problem Posing to Enhance Problem Solving Processes for Pythagorean Theorem of Mathayomsuksa 2

Abstract

This research aims to study Problem Posing to Enhance Problem Solving Processes for Pythagorean Theorem of Mathayomsuksa 2 studying in Mathayomsuksa 2 at Thawatburi Wittayacom School in Amphoe Thawatburi, Roi-et province in the second semester of academic year 2016. There are 37 students acting as samples of this study by From the classroom, which was acquired by random sampling (Cluster Random Sampling) of 5 classrooms. The researcher learned by using 7 learning plans to study problem posing and use problem solving tests to solve problem solving. The statistics used in the research were frequency, percentage, mean, and standard deviation. Data analysis uses basic statistics. Then presented by descriptive analysis. The research found that students can problems posing by doing exercises in the plan, First the relationship of the right triangle = 3.43 S.D. = 0.68, followed by the Pythagorean theorem = 3.16 S.D. = 0.66, the apply the Pythagorean theorem = 3.01 S.D. = 0.77, the Pythagorean Theorem. = 2.73 S.D. = 0.82, Pythagorean Theorem = 2.87 S.D. = 0.75, the problem with theorem Return to Pythagorean theorem = 2.69 S.D. = 0.99 and solved using the Pythagorean theorem = 2.61 S.D. = 0.89 Average score is 2.93 from the full grade of 4 points. In this study, from the problem solving test, students were able to score higher average math problem solving ability at all stages. By implementing the plan increased to 0.95 at a good level. Checkout increased to 0.94 at a good level. Understand the problem increased to 0.99 at a good level. Plan to solve problems increased to 1.01 at a good level.
