Abstract

Misconceptions still often occur when learning physics, especially in conducting research that is not consistently detailed in identifying an observation. In parabolic motion material, it is known that 45° is a special angle that produces the farthest distance. The misconception that 45° is the angle that produces the farthest distance has become a reference in learning in various educational institutions to date. The aim of this research is to identify and prove that the 45° angle is not an elevation angle that produces the farthest distance in a vacuum that ignores the initial position of the thrower. This research was conducted using PhET virtual laboratory media which was analyzed based on quantitative and qualitative methods. This study will test the elevation angle of 42° : 45° : 48° based on altitude 0 m : 1 m : 2 m. After the observational data has been obtained and proven by the existing equations, the research results will be analyzed based on the functional analyzer approach by making the equations into function graphs to make it easier for readers to read the existing data. In this study, it was found that the angle of 42° is the producer of the farthest distance and also gets a relatively faster travel time compared to the angle of 45° which we know so far as a special angle that produces the farthest distance in non-vacuum conditions.

Abstract

Students' difficulties with gas kinetic theory material have led to low mastery of physics concepts. Improving mastery of the concept of the kinetic theory of gases can be supported by using learning models. There have been many studies that prove that discovery learning can influence physics learning outcomes. However, this study uses a STEM approach integrated into a discovery learning model that acts as part of the inquiry level in physics classes Merdeka curriculum. This research aims to improve students' mastery of concepts in the kinetic theory of gases material through the STEM-discovery learning model. This research used a one-group pretest and posttest design on 30 students of class XI Merdeka 4 at SMAN 1 Dolopo. The instruments used are the RPP and five questions describing the concept mastery test. The data obtained was then analyzed using the normality test, difference test, N-gain, and effect size, and categorizing the students' concept mastery level for each question. The results of this research reveal that STEM-discovery learning is able to increase students' mastery of concepts in kinetic gas theory material. Interestingly, this research also found that students' correct conceptions have not been able to be stored in memory very well, so it is necessary to link kinetic gas theory material to other physics material that is still relevant so that students are motivated to remember and retain concepts.
