In some school, teacher-centered is commonly found in the learning process. The learning process itself is still in the form of direct transfer of knowledge from teacher to students. Actually, students will learn better if they are engaged in meaningful learning activity.  STEM project-based learning is one of alternative teaching strategies that engaged students in meaningful learning. The aim of this study is to investigate the impact of STEM project-based learning on students' creativity in the topics of light and optics.  The study used qualitative research with narrative design. Data collection technique that used is observation. The population is eight grade students in one of Junior Secondary School that is located in Bandung, Indonesia. The sample consist of 25 students that chosen based on purposive sampling technique. The data is obtained through Creativity Product Analysis Matrix (CPAM). There are three creativity dimension that used in this study which are resolution, elaboration and novelty dimension. Students’ creativity is obtained as much 76% which categorized as good. Based on the result, STEM project-based learning give the good impact on students' creativity. STEM project-based learning can be used as alternative teaching strategies in Junior Secondary School.

Scientific learning in schools requires not only students’ ability to understand concept, but also critical thinking abilities of the students. However, the current scientific learning process is still focused on only cognitive aspects. Therefore, a teaching model or strategy that is able to support students to understand concept as well as develop students’ critical thinking abilities is needed. One of the existing needed strategies is Predict-Observe-Explain (POE). The aim of this research is to identify the effects of Predict-Observe-Explain (POE) strategy on students’ conceptual mastery and critical thinking in learning vibration and wave. The method that was used in this research was weak experiment and the design was one-group pretest-posttest. The population of this research was 8th grader students in a junior high school in Bandung. The sample of the research was 18 students. The technique that was used was purposive sampling. The results of the research were: There was enhancement in students’ conceptual mastery, indicated by average normalized gain of 0,29; There was enhancement in students’ critical thinking abilities from level 1,30 (challenged thinker) to 2,07 (beginning thinker). Students can easily predict, observe and explain waves concept have difficulties on transversal waves and longitudinal waves concepts. For the next research it is recommended that Predict-Observe-Explain (POE) is to be tried on motion, electricity and ecosystem.

Engineering is one of the crucial parts of STEM Education. The Engineering Design Process (EDP) is a new trend within science education reform. Most science teachers lack information regarding the usage of EDP in learning science. This study aims to review 40 articles from reputable international journals such as indexed by Scopus and Web of Science (WoS), which explains the steps of the EDP used in science education. The articles selected for review were the ones published in the last ten years, from 2011 to 2020. Some previous literature review studies focused on the EDP through projectoriented capstone courses, the EDP in middle school settings, and how to implement the EDP in science learning. However, this study focuses on the steps of the EDP used in science education (Science, Physics, Biology, Chemistry, and a combination of science with other disciplines). In addition, this research also explains the strengths and weaknesses of EDP in science education. The research approach used was a systematic literature review. This study analyzed the representation of research according to their general characteristics consists of type of publication, year of publication, country, research approach, educational level, and science content. This study found that research on the EDP that is implemented at the university level is still limited, especially on subjects related to interdisciplinary knowledge. Furthermore, the steps of the EDP used in science education differ from one research to another. The most commonly used steps of the EDP are defining the problem, building, testing, evaluating, and redesigning. There are also several obstacles to the implementation of the EDP in science education. Regardless, the implementation has a positive influence on students, undergraduate students, teachers, or others. The results of this study provide an overview of how to implement the EDP in science education. Thus, it can be used as a reference for stakeholders in the field of science education when implementing EDP in their learning.

This paper describes students content knowledge of STEM in the process of project based learning. The selected project in this study is renewable energy (solar power), because Indonesia is located on the equator line which gets abundant sunlight as well as to popularize alternative energy in Indonesia as an effort to prevent global warming. This study was designed to determine the effectiveness of Solar Power Project to promote students content knowledge of STEM. The subjects were 28 pre service physics teachers divided into seven groups. This research used both qualitative and quantitative methods (mixed methods). Pre-test and post-test of STEM knowledge as quantitative data were conducted to determine students’ achievement and the effectiveness of learning. Furthermore, the shift of students STEM knowledge was tracked using video recording, task, reports, and interviews. Quantitative data were analyzed using a paired t test, whereas quantitative data were analyzed by triangulation of data. The results of the study showed that science content knowledge experienced the largest increase, followed by engineering, technology and the last is mathematics. Conclusion, solar power project can be helpful in enhancing students achievement of STEM knowledge and generate meaningful learning.

Sustainability awareness is one of the things that the student should have to help in a caring environment. Sustainability awareness of the student can be built by knowledge and awareness of what should be done or not. The student will be more aware of the students involved and explore more in building a concept about the environmental issue itself. The aim of this study is to investigate the impact of Argument-Driven Inquiry toward students' sustainability awareness in learning global warming. The method used in this research was experimental research. This study used two different groups of student. The first group learned using Argument-Driven Inquiry and the second group learned using Inquiry-based Learning. The population was seventh-grade students in one of Junior Secondary School in Bandung, Indonesia. The purposive sampling technique was used to choose the sample. The participants consist of 52 students from both groups. Each group consists of 26 students. The data were collected by giving the questionnaire of sustainability awareness. The questionnaire consists of 15 items. The result of this study shows the different percentage in the level of students' sustainability awareness between the two groups. The most different percentage is on the sustainability practice awareness aspect. The group that used Argument-Driven Inquiry has percentage 40.7% which means as medium and the group that used Inquiry-based Learning has percentage 37.6% which means as low. Based on the result, Argument-Driven Inquiry gives a better impact on students’ sustainability awareness. Argument-Driven Inquiry can be considered as one of the alternative teaching models that can give a better understanding in building the awareness of Junior Secondary School student.

Located in the Pacific Ring of Fire, Indonesia is endangered by natural disasters. Through the changing of learning activity in a proper way by the application of STEM Project-Based Learning, future generations are expected to develop the knowledge and thinking skill to solve the problem. Therefore, this study aimed to investigate implementing STEM Project-Based Learning on student's Problem-Solving Skills.

In addition, Idea-Finding is the most significant improvement during the Fact-Finding on the lowest. Based on the result, STEM Project-Based Learning is recommended to improve students' Problem-Solving Skills since they can use their integrated knowledge to solve a real-world problem.

Electrochemistry is difficult to learn due to its abstract concepts involving macroscopic, microscopic, and symbolic representation levels. Studies have shown that students can visualize and improve their understanding of chemistry by using interactive computer animation and simulation. This study reports the effect of interactive computer animation and simulation module named “Interactive Electrolysis of Aqueous Solution” (IEAS) developed to aid students in learning electrolysis. A pre and post-test control quasi-experimental design was carried out to investigate the effects of the IEAS on students’ achievement and motivation in electrochemistry topics. This study involved 62 16-years-old male students from two different secondary schools. Pre and post electrochemistry achievement tests (EAT) and pre and post- Instructional Material Motivation Surveys (IMMS) were used. For EAT, using one-way ANOVA, it shows that there was a significant difference in the post-test mean score in this study on the understanding of the electrolysis concept between students in the treatment and control groups [F (1, 60) = 5.15, p <0.05]. The qualitative results also provided evidence that the students in the treatment group had a better conceptual understanding than the control group, especially at the microscopic representation level. For the IMMS test, there was a significant difference between the treatment and control groups in terms of the mean score of the post motivation IMMS test where p <0.05 in chemistry learning [F (1,59) = 266.89, p <0.05].  Thus, it can be concluded that IEAS has an impact on enhancing the students’ understanding of the electrolysis concept, and the students are more motivated to learn electrochemistry.
