Development of Learning Package with KWDL Technique to Enhance Academic Achievement and Chemistry Problem Solving Skills for Mathayomsuksa 4 Students

Abstract

             The objectives of this research were: 1) to develop a learning package with KWDL technique on the topic of Stoichiometry for Mathayomsuksa 4 students, to achieve an efficiency standard of 80/80 and an effectiveness index (E.I.) of at least 0.50, as per the established criteria, 2) to compare the academic achievement in chemistry before and after using the KWDL learning package, 3) to compare problem-solving skills in chemistry before and after using the KWDL learning package, and 4) to study the students' satisfaction with the learning process using the KWDL learning package. The sample group consisted of 40 students from Mathayomsuksa 4 students at Bangsawan Witthayakhom School. The data were analyzed using the percentage, mean, standard deviation, and t-test.
             The research results found that:
             1. The KWDL learning package on Stoichiometry had an effectiveness (E₁/E₂) of 80.33/80.56, which met higher than the standard criteria of 80/80, and the effectiveness index (E.I.) is 0.68, which was higher than the standard criteria of 0.50.
             2. The post-test academic achievement was significantly higher than the pre-test at the .01 level.
             3. The post-test problem-solving skills were significantly higher than the pre-test at the .01 level.
             4. The students' satisfaction with the learning process using the KWDL learning package was at a high level, with an average score of 4.38.
