An Action Research on Development of Mathematic Learning Achievement in the Inequality of Matthayom Suksa 3 Student, Sompoipittayakom School By Problem–based Learning Approach

Abstract

The purposes of this research were: 1) to study the development of mathematic learning achievement in the inequality by Problem–Based Learning Approach.  2) to study the growth score of mathematic learning in the inequality after learning by Problem–based Learning Approach and 3) to study the satisfaction of student learning by Problem–Based Learning Approach. The instruments used in this research were: the inequality by Problem–Based Learning Approach plans, the mathematic test, the problem solving skill observation form, the inquiry learning observation form, and the satisfaction form.The statistics for the data analysis were frequency, percentage, means, standard deviations and growth score.

            The research findings were as follows

1. A development of mathematic learning achievement in the inequality by Problem–Based Learning Approach was five ladder system circles; each circle was Plan Action Observation and Reflection. This learning made students improved mathematic learning outcomes.
2. students had a growth score of mathematic achievement in the inequality they have got high score developmental
3. students have a satisfaction of mathematic learning achievement by Problem–Based Learning Approach. The overall of the satisfaction level is excellent.
