Abstract
The purposes of this research were: 1) to develop the infographics on Google’s online platform in order to reach the efficiency of the 80/80 threshold set, and the effectiveness index more than 0.50; 2) to examine the effects of using the infographics on Google’s online platform to enhance English grammar learning achievement of student teachers; and 3) to investigate the student teachers’ satisfactions towards teaching English grammar by using the infographics on Google’s online platform. The samples were two groups of student teachers in Faculty of Education at Suratthani Rajabhat University, who enrolled in the English for Communication Course in the semester 2 of the academic year 2022, selected by using the random sampling method. The random assignment was employed to specify the groups as the experimental group consisted of 30 student teachers, and the controlled group consisted of 29 student teachers. The research instruments were: 1) the developed infographics on the Google’s online platform; 2) twelve lesson plans of teaching English grammar by using the infographics on Google’s online platform; 3) twelve lesson plans of teaching English grammar by the traditional teaching method; 4) the English grammar learning achievement test; and 5) the questionnaire of student teachers’ satisfactions towards teaching English grammar by using the infographics on the Google’s online platform. The data were statistically analyzed using the efficiency (E1/E2), effectiveness index (E.I.), mean (M), standard deviation (SD), percentage (%), t-test, and effect size (Cohen’s d). The findings showed as follows:
1. The infographics on the Google’s online platform reached both the efficiency at 91.75/83.56 and the effectiveness index at 0.73 which were higher than the set criteria.
2. The English grammar learning achievement of the student teachers taught by using the infographics on the Google’s online platform was higher than the controlled group taught by the traditional teaching method at the .05 level of statistical significance with the huge effect size (Cohen’s d = 1.83), and the post-learning achievement in English grammar of the student teachers taught by using the infographics on the Google’s online platform was higher at the .05 level of statistical significance.
3. The student teachers’ satisfactions towards teaching the English grammar by using the infographics on the Google’s online platform were at the highest level (M = 4.56, SD = 0.02).
