The students’ post-test learning achievement (72.31%) was higher than their pre-test achievement (56.89%), showing an improvement of 15.42%. In addition, the students’ satisfaction with the teaching and learning process was at the highest level, with a mean score of 4.96 or 99.20%, and a standard deviation of 0.21.
