The Development of a Learning Activity Set Using Polya's Problem-solving Techniques Combined with Graphic Diagrams in Mathematics for Business and Services Course of the 1st Year Vocational Certificate Students, Suratthani Technical College

Abstract

The purposes of this study were to: 1) develop and validate the efficiency of the learning activity set by using Polya's problem-solving techniques combined with graphic diagrams based on the standard criteria of 80/80, 2) compare the students’ learning achievement before and after learning by using Polya's problem-solving techniques combined with graphic diagrams, and 3) study the satisfaction of students learning with the set of learning activities using Polya's problem-solving techniques combined with graphic diagrams.       The sample consisted of 30 students of the 1^st year vocational certificate students, Suratthani Technical College derived by the classroom as the randomization unit. The research instrument consisted of a learning activity set, a lesson plan using Polya's problem-solving techniques combined with graphic diagrams, the test to evaluate learning outcomes on knowledge and problem solving skills, and questionnaires on students’ satisfaction on the learning activity set. The research statistics included percentage, mean, standard deviation, and t-test.

The results of the study were as follows.  1) The set of learning activities using Polya's problem-solving techniques combined with graphic diagrams reached the efficiency value of 83.64/86.00 higher than the specified criteria. 2) The results of the students’ academic achievement after learning with the activity set using Polya's problem-solving techniques combined with graphic diagrams was higher than that of the pre-test with the statistically significant level of  .05. Finally, 3) the students reported their satisfaction at a high-level.
