This research is concerned with STEM activity making water purifier filter. The experiment class applies project-based learning, while the traditional class is taught using conventional teacher talk or explanation. This research used triangulation methods. The quantitative methods were applied to analyze student achievement tests according to creative thinking skills in making water filtration design. The qualitative method was applied using observation of student activity, presentations, and interviews for selected students. The student achievement test was analyzed and coupled with pretest and post-test quasi-experimental research. The collected data were analyzed using inferential statistics in the form of an independent sample t-test to express creative thinking skills. The result of the pre-test indicated the sig (2-tailed) of 0.965, with a significant value of 5% (p>0.05). This result indicated two classes were homogenous. The data analysis of the post-test indicated value of sig (2-tailed) 0.00 where p≤0.05, which implied the student achievement test on creative thinking skills criteria in the experimental class was better than that in the control class.

This research aims to explore students’ computational thinking skills within the implementation of the Research-Based Learning model of Teaching in Astronomy course in Kepler and Titius Bode Laws topics. The research design is comparing the modern class (experimental class) and traditional class with the traditional teaching type. RBL model of Teaching implemented in the experimental class, while direct Teaching implemented in the control class. Computer programming is also integrated into this research related to computational thinking skills. Matlab Software used in this research related to Astronomy course of Kepler’s and Titius Bode’s Laws topics. This research used triangulation methods. The quantitative methods were applied to analyze students’ achievement tests according to computational thinking skills. The Qualitative method was applied using the observation of students’ activity. Students’ achievement tests are represented by pretest and posttest scores. The posttest results for the experimental class were 80.4167 and the control class was 75.8108. The data analysis form pretest and posttest scores indicate a significant value of 0.012 (p ≤ 0.05) with the gain in mean that also emerged in both classes. The average value of student activity for the experimental class was 3.7444 and the control class was 2.4266 from a maximum value of 5. This research results that the RBL accompanied with computer simulations have a significant impact towards students’ computational thinking skills.

The purpose of this research is mapping teacher perception on learning management system as second opinion in pandemic era. The methodology of research divided into three parts, namely preparation, action, and evaluation. The first step is preparation, include prepare to train the teacher to use CCR and android application opensourse. The second step is action, this section is most important in this research because in this section the teachers were practicing with CCR and android application within the teaching activities in online learning. After those steps, the final is evaluation, the teachers were evaluated using likert scale of the implementation of CCR and android open sourse. The result  of this research is most of the teachers feel easy in accessing CCR and android opensource application.

This study aims to see is there a significant effect of the use of PhET simulations in science learning of static liquid pressure topics towards creative thinking skill of middle school students. This research was conducted at SMPIT Al-Ghozali Jember in 8th grade of C class and D class where each class consisted of 21 female students. The design of this research is Control Group Pretest-Posttest in which the learning in experimental class uses the PhET simulation while in control class uses the experimental video. The results of Wilcoxon Signed-Rank Test on students' creative thinking skill test scores are differed significantly both in the experimental class and the control class. The results of Mann-Whitney test are the students' student worksheets in the experimental class differed significantly from the control class. It can be concluded that there is a significant effect of the use of PhET simulations in this study.

This Research have a purpose to exploring teachers’ preference on development of learning media integrating assessment with android application as online assessment in science learning in SMP Cendekia Insani. Research and development use an ADDIE Model. Steps of ADDIE Model is Analysis, Design, Development, Implementation and Evaluation. Analysis is the steps description process of what is going to be taught and forms the basis of all other steps. Design is determine the process of have an information and development a strategy of analysis the problem. Development the component of multimedia are prepared during this phase. Implementation is development result is applied in learning process to know it’s the quality. Evaluation is the last step to evaluation and have a data to improve a research. This research have a result of most of the teachers prefers the online assessment that integrated with android application rather than the conventional one especially in the online learning environment nowadayas.
