Abstract

Problem - Based Learning Activities on Mathematical Problem Solving Ability and Reasoning Ability of Mathayomsuksa Three Students on “Mathematical Processes and Skills” 

The purposes of this research were 1) to study ability in solving mathematical problems on “Mathematical Processes and Skills” by problem - based learning activities, 2) to study ability in mathematical reasoning on “Mathematical Processes and Skills” by problem - based learning activities, and 3) to study students’ opinion related to problem - based learning activities on “Mathematical Processes and Skills” of mathayomsuksa three students at Satthasamut School, Changwat SamutSongkhram. The sample group was 47 mathayomsuksa three students of one classroom at Satthasamut School, Changwat SamutSongkhram in the second semester of the academic year 2014 that was selected by cluster random sampling from 12 classrooms. The instruments in research are divided into two types. 1) The experimental instrument was lesson plans by using problem - based learning on “Mathematical Processes and Skills”. 2) The instruments in data collection consisted of the ability tests in solving mathematical problem on “Mathematical Processes and Skills”, the ability tests in mathematical reasoning on “Mathematical Processes and Skills”, and students’ opinion questionnaire towards problem - based learning activities on “Mathematical Processes and Skills”. Percentage, mean, standard deviation, and t – test were used for analyzing data.

The research findings revealed that the ability in solving mathematical problems of mathayomsuksa three students that learnt by using problem - based learning activities after learning was higher than before learning at the .05 level of significance and was higher than 60% at the .05 level of significance. The ability in mathematical reasoning of mathayomsuksa three students that learnt by using problem - based learning activities after learning was higher than before learning at the .05 level of significance and was higher than 60% at the .05 level of significance and almost all students agreed to strongly agreed that the problem - based learning activities were appropriate.
