DEVELOPMENT OF A LEARNING MANAGEMENT TOOL FOR MATHEMATICS ON ADDITION, SUBTRACTION, MULTIPLICATION, AND DIVISION OF WHOLE NUMBERS FOR GRADE 4 STUDENTS

Abstract

The objectives of this research were: 1) to evaluate the quality of learning management plans on addition, subtraction, multiplication, and division of counting numbers for Prathomsuksa 4 students, and 2) to assess the quality of a learning achievement test. The sample group consisted of five experts and 20 students. The statistics used for data analysis included mean, standard deviation, item-objective congruence, difficulty index, discriminative power, and Cronbach's alpha reliability coefficient.

The research findings were as follows: 1) The overall quality of the learning management plans was rated at the highest level, with a mean score of 4.90 and a standard deviation of 0.33; and 2) The developed learning achievement test comprised 42 validated items, with item–objective congruence values ranging from 0.60 to 1.00. The test demonstrated its difficulty index ranging from 0.50 to 0.88, discrimination power from 0.25 to 0.88, and Cronbach’s alpha reliability coefficient of 0.88.
