Development of Learning Achievement and Calculation Skills in Stoichiometric by Using Inquiry Method (5E) with KWDL

Abstract

The purposes of the study were 1) to develop the learning outcome and calculation on the stoichiometry through the 5E learning activities with KWDL of Mathayomsuksa 4 reliably, 2) to compare pretest and posttest the learning outcome and calculation on the stoichiometry through the 5E learning activities with KWDL of Mathayomsuksa 4, 3) to study thecalculation skills on stoichiometry through the 5E learning activities with KWDL of Mathayomsuksa 4, and 4) to investigate the students’ satisfaction on stoichiometry through the 5E learning activities with KWDL of Mathayomsuksa 4. The instruments were 1) the lesson plans, 2) the learning outcome examination, 3) the calculation test, and 4) the questionnaire. The participants were 10 Mathayomsuksa 4 students at Kerng Wittaya School, the Provincial Administrative Organization in the semester 2, academic year 2018 from the cluster sampling.

          The results of the study shown that;

           1) The reliability of the lesson plans was 61.70/71.00.

           2) The comparison of the pretest and posttest found that the learning outcome of the posttest was higher than the pretest significantly at .01.

            3) From the calculation test found that the students’ skills were at the high level which 60%.

           4) The students’ satisfaction was at the high level (= 4.02, S.D. = 0.82)
