The development of harmonic oscillation e-module based on problem based learning (pbl) for helping improvement of students' higher order thinking skills (hots)

This study aims to develop a harmonic oscillation e-module based on pbl for helping hots improvement of senior high school students at SMA N 23 Jakarta. The ADDIE Model of research and development was applied in developing such e-module prior to measure improvement of students' hots. The validation results of experts indicated the values of 78.1%, 77.7% and 93.8% for media, learning model and content, respectively. The trial result of teachers and a small and big groups of students respectively indicated an average score of 93.95% and 95.1% and 86.5% for all aspects of content eligibility, presentation, language and graphical eligibilities. Furthermore, The tgain test calculation shown that the tgain count (2.58) was bigger than tgain table (1.67) with 5% significance level. The analyzed result indicated that the improvement of hots of students which was taught with the pbl based e-module was better than those who utilized the non pbl based e-module of the harmonic oscillation. Whiles, the result of d'Cohen test indicated that the developed e-module was very decent to be utilized as learning media with contribution category of medium (based on d'Cohen test result of 0.64) for improving hots of senior high school students.
