Abstract

Creativity is one of the skills that must be possessed in the 21st century, especially by pre-service science teachers. However, in fact, the quality of pre-service science teacher creativity still needs to be improved. Therefore, this research aims to increase the creativity of pre-service science teachers through STEM Problem-Solving. This research uses a one group pretest posttest design. The sample in this study was 53 pre-service science teachers in the science education department at Universitas Negeri Surabaya. Increasing the quality of pre-service science teacher creativity is measured based on pretest and posttest scores. The pretest and posttest scores were then analyzed using N-Change. Apart from that, it was also analyzed statistically using paired t-test. This is used to ensure that STEM Problem-Solving really has an effect on increasing the creativity of pre-service science teachers. The research results show that STEM Problem-Solving is proven to significantly increase the creativity of pre-service science teachers. The category of increasing pre-service science teacher creativity is in the medium category. The majority of pre-service science teachers' final creative quality is in the creative category.

Abstract

Future challenges for learning require students to not only master concepts, but also develop thinking skills, one of which is problem solving skills. The aim of this study was to identify the effect of Experiential Learning with STEM-Computational thinking (STEM-CT) approach on students' problem solving skills. This research falls under a quasy experiment type with pretest-posttest control group design involving  60 students in 11th grade, especially on static fluid topic. The author collected quantitative data through pre-test and post-test, to assess the difference in students' problem solving skills between the experimental and control groups. Data analysis was carried out using parametric statistics, namely independent sample t-test, and obtained sig. 2 tailed of 0.001 which meets p < 0.05, so it can be concluded that there are differences in problem solving skills between the control class and the experimental class, after being given different treatments. The average N-Gain scores of the experimental class is also higher than control class. It indicates the effect of experiential learning with STEM-CT approach on students' problem solving skills. In the future, more in-depth research is needed related to the effect of experiential learning on various other thinking skills, especially in physics learning.

Abstract

This study aims to identify students' reasoning abilities and learning difficulties related to Newton's Laws through a systematic literature review using the PRISMA method. The review analyzes seven scientific articles published between 2020 and 2024 in SINTA-accredited journals, international conference proceedings, and Scopus-indexed sources. The findings indicate that students’ reasoning abilities regarding Newton's Law are still low, with an average conceptual understanding of only 33.3%. Common difficulties faced by students include interpreting Newton's First Law (inertia and constant velocity), understanding the relationship between force, mass, and acceleration in the Second Law, and the action-reaction principle in the Third Law. These difficulties are generally caused by the abstract nature of the concepts and students’ weak logical reasoning skills. The review also highlights the need for effective instructional strategies. Contextual teaching, problem-solving-based learning models, and metaphorical thinking approaches are proposed as potential solutions. These strategies are considered effective in enhancing students’ conceptual understanding and scientific reasoning abilities when implemented appropriately. The findings provide valuable insights for educators to design more targeted instructional interventions and contribute to improving learning outcomes in physics education, particularly in Newtonian mechanics.

Abstract

Conceptual understanding and problem solving is the most crucial part of Physics Lectures. In lectures, mastery of the concept is the primary goal. This research aims to analyze students' mastery of physics concepts in the material of Force and Motion while lectures are conducted online. This study uses a mixed-method approach to explain students' answers that still need clarification. Data analysis was carried out using the Rasch model, and a questionnaire was developed based on the possibility of students' responses to the concepts of force and motion. The results of this study indicate that students' understanding of the concept of force and motion material still needs to improve, namely 64.062%, around 94% of glasses tadris students think that the force and motion material given by lecturers during exams is challenging. More than 60.94% of students believe this is because the ability of the force and motion material they have still needs to improve. These results are interpreted based on analysis through the winstep application Version 3.65.0. and for qualitative data obtained from interviews. It takes a learning model that is appropriate for use in online and offline learning.
