A Development of Mathematics Reasoning Ability Through the Heuristics Thinking Model for Prathom Suksa 3 Students of Ban Nongkhun School under Ubon Ratchathani Primary Educational Service Area Office 3

Abstract

The research aimed to develop the mathematics reasoning skills and study the results of the development of the mathematics reasoning skills through the heuristic thinking model for Pratom Suksa 3 students of Ban Nongkhun School under the Ubon Ratchathani Primary Educational Service Area Office 3.  The target group in the research was 16 Prathom Suksa 3 students.  The research instruments were 1) the lesson plan based on the heuristic thinking model,  2) the test for the mathematics reasoning skills,  3) the end-of- the- circle quiz, 4) the observation record,
5) interviews, 6) daily records.  Statistics used in data analysis were percentage, mean, and standard deviation.

The research findings were as follows.

1. The development of the mathematics reasoning skills through the heuristic thinking model consisted of five steps: 1) reading and thinking, 2) surveying and planning, 3) choosing the way to solve the problem, 4) implementing to find the answer, 5) reflecting and evaluating.

    It was found that the learning management based on the heuristic thinking model was the activity which enhanced the students’ independence in thinking, and seeking the answer by themselves through a variety of the methods by linking the learned knowledge with the prior one.  By doing so, the students were able to examine the answer in a rational manner.

1. The students whose learning was based on the heuristic thinking model developed the mathematics reasoning skills by the average of 47.92%. All students scored 60% of the passing criterion out of the total scores.
