DEVELOPMENT OF MATHEMATICS SKILL EXERCISES USING KWDL TECHNIQUE TO ENHANCE PROBLEM SOLVING ABILITY ON PERCENTAGE FOR PRATHOMSUKSA 5 STUDENTS

Abstract

The purposes of the research were to; 1) develop mathematics exercises using KWDL technique with an efficiency of 75/75, 2) compare the learning achievements of students, before and after teaching by KWDL technique, 3) compare mathematic problem solving skills of students, before and after teaching by KWDL technique, 4) explore satisfaction of students on the mathematics skill exercises using KWDL technique. The samples used in the study were

14 Prathomsuksa 5 students studied in semester 2, academic year 2019, at Ban Lahan Apirakwittaya School, obtained using the Simple Random Sampling technique. The research instruments consisted of mathematics exercises using KWDL technique, lesson plans, achievement test, mathematics problem solving test, and a rating scale questionnaire on students’ satisfaction. The statistics used to analyze the data were mean, standard deviation, percentage, E.I., t-test (Dependent Samples) and z-test (Population Proportion). The results of the study indicated that: 1) the mathematics skill exercises using KWDL technique had an efficiency of 80.69/78.10, which was higher than the criterion, 2) the students showed gains in learning achievement from before learning at the .01 level of significance, 3) the students showed gains in mathematics problem solving from before learning at the .01 level of significance, and also 4) the students showed gain in satisfactory on learning at highest level.
