Abstract:
The purposes of this research were: 1) to study efficiency of learning activities through flipped classroom with Microsoft Team on plant propagation for grade 11 students based on the criterion 75/ 75, 2) to compare learning achievement before and after learning through flipped classroom with Microsoft Team on plant propagation for grade 11 students, and 3) to study life skill of students toward learning activities through flipped classroom with Microsoft Team on plant propagation.The research samples were 30 grade 11 students who studied at Piboonbumpen Demonstration School. They were randomly selected by cluster random sampling. The research instruments consisted of 4 lesson plans of learning activities through flipped classroom with Microsoft Team on plant propagation for grade 11 students, the achievement test, and the life skill assessment form. The statistic used in this research were percentage, mean, standard deviation and t-test for dependent sample. The results of this research were: 1. Learning activities through flipped classroom with Microsoft Team on plant propagation for grade 11 students possessed the efficiency (E1/ E2) of 77.25/ 76.44, which was higher than the set of 75/ 75 based on the standard criteria 2. The grade 11 students posttest mean scores of learning achievement with activities through flipped classroom with Microsoft Team on plant propagation was statistically significantly higher than the pretest mean scores at the .05 level. 3. The life skill of the grade 11 students towards learning by using activities through flipped classroom with Microsoft Team on plant propagation as a whole was at a good level.
