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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
