Development of Computational Abilities of Primary 3 Of Chumchon Maitri Uthit School Using the Skill Sets for Addition and Subtraction of Counting Numbers Whose Results and Augend and Minuend do not Exceed 100,000

Abstract

            The research purposes were (1) to develop the skill training sets (2) to compare the achievements of addition and subtraction of counting numbers whose results and augend and minuend do not exceed 100,000; and (3) to study the satisfaction of Primary 3 students of Chumchon Maitri Uthit School on learning by using addition and subtraction of counting numbers whose results and augend and minuend do not exceed 100,000. The sample group was the 24 Primary 3 students of Chumchon Maitri Uthit School under the Jurisdiction of Nonthaburi Primary Educational Service Area Office 2, selected by the purposive sampling. The research instruments were (1) the skill training sets, (2) the learning achievement test, and (3) the student satisfaction questionnaire on learning by using the skill training sets of addition and subtraction of whose results do not exceed 100,000. The data analysis statistics were the percentage, mean, standard deviation, and t-test.

               The research findings were:

1. The skill training sets of the addition and subtraction of counting numbers whose results and augend and minuend do not exceed 100,000 had the efficiency 82.28/81.67 percent according to the given.
2. The post-learning achievement of Primary 3 students was higher than before at the statistical significance level of .05 according to the hypothesis.
3. The students’ satisfaction on learning the mathematics skill group, on solving the problems learned by using the skill training sets of addition and subtraction of counting numbers whose results do not exceed 100,000 found the overall was at high level.
