The STEM is an interdisciplinary approach provided learning atmosphere where students can use science, technology, engineering and math in daily life. The aim of the STEM is educating the students to be STEM Literate. This research goal was to implement STEM learning on electricity using Arduino-Android Game based experiment to 8th-grade students. STEM Learning was chosen as an approach in this research by the consideration that it was developed through Android Game, YWRobot, and Arduino Uno experiment lesson plan and worksheet. The analysis of this research was focused on the effect of STEM learning implementation through lesson plan and worksheet to 8th-grade students’ STEM Literacy on electricity topic. The method used in this research was pre-experimental with one group pretest-posttest design. The data of this research was obtained from the STEM Literacy objective test (pretest and posttest) based on Allan Zollman. Then the data were analyzed based on each aspect of STEM Literacy such as science, technology, engineering, and mathematics. The result shows that the value of  from students’ STEM Literacy pretest-posttest are -0.06, -0.12, -0.06, -0.87 for science, technology, engineering and mathematics literacy respectively. The result implies that STEM Learning implementation was less optimal to improve science, mathematics, technology and engineering literacy. The reason was because STEM Learning implementation was not implement in continuously. Therefore, science, technology, engineering, and technology literacy regarding electricity topic are emphasized less optimally.

The objectives of this study were to profile the relationship of scientific attitude level and learning style preference among junior high school students in Bandung. This study utilized a survey research design with a total sample size of 110 students. A scientific attitude questionnaire and a visual, auditory, and kinesthetic (VAK) learning style inventory were administered in this study. The questionnaire measures five aspects of scientific attitude, specifically rationality, curiosity, open-mindedness, aversion to superstition, and objectivity. The VAK learning style inventory evaluates the preferred means of receiving sensory information. The scientific attitude questionnaire provided consistent results, as indicated by its reliability coefficient (0.896). The results show that junior high school students have an average level of scientific attitude and generally prefer a kinesthetic learning style.  There was a medium relationship between scientific attitude and learning style among the students (Cramer’s V coefficient = 0.239).  It is concluded that learning style must be considered in implementing a science lesson, especially in the Indonesian context.

Different types of skills are required to be able to remain competitive in 21st-century global developments, particularly in science, technology, engineering, and mathematics fields. The purpose of this study was to investigate the influence of STEM project-based learning on students’ motivation in learning heart transfer. The pre-experimental method with one group pre-test post-test design was implemented. The sampling technique used in this study was convenience sampling. The samples of this study consist of 26 students who come from two different schools in 7th grade. Student’s motivation is measured using the SMTSL questionnaire, and the data result analyzed using SPSS software. The result of this study showed that the implementation of STEM project-based learning gives an improvement in students’ motivation significantly. Although N-gain values are 0.06, which categorized as low levels, the statistical test shows that there is a significant difference before and after the implementation of STEM project-based. According to this research, STEM project-based learning can be an alternative strategy to improve students’ motivation towards science learning.

The research is the first research that opens up our Universe from a mobile application called Solar Walk Ads+: Explore Space to improve students' understanding and believe in learning Solar System. The work has begun to collect the data of students' post-test and pre-test using quasi-experiment design participated by 12 students in 7th grade of a private school in Bandung, West Java. The data was analysed based on three different concepts, the higher improvement shows in the concept of the Solar System's effect on the phenomenon on the Earth. Meanwhile, the students' believe effect after learning with this application resulted in the better improvement shown for the lower achiever students rather than the higher achiever students. Finally, this research recommended to held research that finds out whether the improvement is better if learning Solar System using Solar Walk Ads +: Explore Space also motivates students to learn.
