Faraday flashlight project-based STEM to enhance problem-solving skill of students

Abstract

The problem-solving skills is one of necessary competence to compete in twenty-first century. However, research about the impact of Project-based learning based science, technology, engineering and mathematics (PjBL-STEM) towards problem solving skills in the topic of electromagnetic induction is still limited. Faraday flashlight project as representative of basic development of modern technology in the topic of electromagnetic. The purpose of this research is to investigate the effect of Faraday flashlight in STEM integrated PjBL learning towards the increase in students’ problem-solving skills. The mixed methods involved 36 senior high school students as participants. The research instrument was the Problem-Solving Skills Test, observation (panduan observasi), and interview. Data were analyzed by paired sample t-Test, N-gain, effect size, and data reduction. The result shows that PjBL-STEM had enough effect on students’ problem-solving skills. This condition was caused by each syntax of PjBL based STEM, which could help students enhance their problem-solving skill. Students’ skills in describing problems, utilization of Faraday induction approach, specific application of physics, and logical progression had increased in medium categories. However, mathematical procedures had a high category. Based on effect size criteria, PjBl based STEM had high effect on all problem-solving skill indicators.
