Online Model-Based Learning Activities on Scientific Explanation in Electrochemistry of Mathayomsuksa 5 Students

Abstract

The present study aimed 1) to compare scientific explanation in electrochemistry of mathayomsuksa 5 students who learned via online model-based learning activities with the criteria of 70%, 2) to compare learning achievement in scientific explanation in electrochemistry of mathayomsuksa 5 students who learned via online model-based learning activities with the criteria of 70% and 3) to investigate mathayomsuksa 5 students’ satisfaction toward online model-based learning activities. The sample was 42 mathayomsuksa 5 students who were studying in the 2^nd semester of 2021 academic year in Phonthongpattanawittaya School by cluster random sampling. The instruments used were 1) lesson plans of online model-based learning activities, 2) test of scientific explanation, 3) leaning achievement test, and 4) questionnaire of students’ satisfaction.  The statistics used were percentage, mean, standard deviation and one sample t-test. The results of the study revealed that; 1) students who learned by online model-based learning activities were able to do the scientific explanation which in line with the criteria of 70% indifferently. Students’ scores were 26.29 of mean which was 73.03 %. When analyzed each elements of the scores of scientific explanation, it revealed that students achieved the element of claim and evidence which was higher than the criteria of 70%. However, students achieved the element of reasoning which was lower than the criteria of 70%. 2) students who learned by online model-based learning activities gained learning achievement scores which was indifferent from the criteria of 70%.  The mean of learning achievement scores was 21.69 which were 72.30 %. and 3) Students satisfied toward the online model-based learning activities rated in high level.
