Abstract

This study aims to study the visualization and GeoGebra operations for the simulation of Lissajous waves as a substitute for the oscilloscope screen. The research subject is GeoGebra software. This research was conducted at the STKIP SoE Science Laboratory. This research is expected to produce visualization and operating system of Lissajous waves on GeoGebra. The data used in this study are fixed amplitude, frequency ratio 1:1 with a phase difference of 00, 450, 900, 1800, 2700, 3600. Other data used is the ratio of frequency equal to amplitude = 2:5 at a phase difference of 900 and 1800. Comparison of the phase difference between 900 and 1800. frequency, amplitude, and phase difference are the main variables in the formation of Lissajous waves. It is concluded that GeoGebra software can be used for simulating Lissajous waves such as on an oscilloscope screen. This simulation media can be used by students and teachers in understanding Lissajous wave patterns.

Abstract

This study aims to analyze the logical-mathematical thinking ability of prospective physics teacher students as a basis for designing learning strategies based on differentiated learning and computer simulation. The survey method involved 37 physics education study program students from one of the universities on the island of Timor. Data was collected through a logical thinking ability test covering five main types of reasoning: proportional, variable control, probability, correlation, and combinatorial. The analysis results showed that most students were at the level of transitional logical thinking (70 percent), while only 11 percent reached the formal level. The chi-squared test showed a significant relationship between the semester level and students' logical thinking ability. These results show the need for learning that supports the transition from concrete and transitional thinking to formal. Implementing computer simulation in statistical physics learning is recommended to improve students' logical-mathematical thinking skills, support the understanding of abstract concepts, and facilitate the success of complex physics learning.
