This research used Deff model adopted from Research & Development by Borg and Gall. The subject used was junior high school students which consists of 45 students. The instruments used were need analysis, expert’s evaluation, small and large group test. Effectiveness test was to know junior high school students’ jump skill level before being given biomechanic treatment. The Pre-test obtained from the students’ jump result was about 540, and Post-test was about 812. The conducted t-test between the experiment group and the control group obtained was t = 10.152 and in the n-gain score test between the experiment group (biomechanic treatment) obtained by 76% (effective) and the control group obtained by 43.40% (less effective). Therefore, this game model is effective in increasing students’ jump learning. According to the result, it could be inferred that: (1) this model can be developed and applied in physical education, (2) the model proved that there are significant difference in pre-test and post-test between the experiment group (biomechanic treatment) and the control group after the treatment model, based on N-gain test.

This research focused on the learning of five tenses, namely the simple present tense, the simple past tense, the simple future tense, the simple present continuous tense, and the simple present perfect tense. A pre-test was employed before the research started and after the treatment had been given to the experimental group, a post-test was given a week after, and another post-test was given three months later. The results show that LBT helps the subjects learn better. Moreover, they also remember their materials longer.

This study investigated the effect of implementing flipped classrooms on Iranian junior high school students' reading comprehension. To this end, 50 Iranian pre-intermediate students were choosen and randomly assigned into two equal groups; one experimental group (flipped classroom) and one control group (traditional classroom). After that, both groups were pretested through a reading comprehension test. Then, the researchers put the respondents of the experimental group in a flipped classroom. The flipped classroom was equipped with Internet, computer and projector. The students were required to read each text before coming the class and discuss it with their classmates. On the other hand, the control group was taught in the traditional classroom. Before teaching each text, the researchers provided background knowledge for the control group and after teaching each text, the students were required to answer some questions related to the text. The whole treatment lasted 8 sessions of 50 minutes. In the last session, the post-test of reading comprehension was administered. The results of paired and independent samples t-tests indicated that there was a significant difference between the post-tests of the experimental and the control groups. The findings revealed that the experimental group significantly outperformed the control group (p < .05) on the post-test.
