Thai The Development of Problem Solving Abilities Using Problem-Based Learning of Grade 11 Students

Abstract

The purpose of this research was to develop problem-solving abilities using problem-based learning of Grade 11 Students to pass the criteria of 70 percent, of the full score. The sample group was 41 students in Mathayomsuksa 5/4 students of Phonthong Pattana Wittaya School, Obtained by random drawing. The instruments used in the research were 1) 6 plans for integration with a problem-based learning plan take timees with 12 hours, 2) 2 sets of the problem – solving ability test and 3) the semi – structure interview. The classroom action research consisted of 2 cycles each one; planning, action observing and reflection. Whereas the action research approach used in this study is composed of 2 spirals, the first spiral is used for the first to the third plan and the second spiral used for the fourth to the sixth plan. The ability test is used after each cycle. The statistics used for data analysis is percentage, mean and standard deviation.   

The result from classroom action research revealed that students who learning using problem-based learning were obviously higher in the problem - solving ability raised from 67.80 in the first loop to 77.56 in the second loop. It showed that the using problem-based learning can develop the ability of students.
