Gender Differences in Basic Physics Laboratory Skills among Biology Education Students: A Quantitative Analysis

Muhammad Taufik — 2023-12-31

This study investigated gender differences in physics laboratory skills among biology education students. A total of 90 students were recruited from three biology education classes at a university in Indonesia. The students completed five physics laboratory activities, and their performance was assessed using a rubric that measured skills in using laboratory equipment, data analysis, and communication. The results showed that there were no significant differences in physics laboratory skills between male and female students. However, there were some trends that suggest that female students may have a slight advantage in data analysis skills. These findings suggest that gender differences in physics laboratory skills may be minimal, and that both male and female students are capable of achieving high levels of performance in physics laboratory courses.

This research was conducted because there was still a low level of critical thinking skills of students in learning Physics. The purpose of this study was to see the improvement of students' critical thinking skills through the application of project-based learning model. The subject of the research is class XI MIPA 2 at SMAN 3 Selong which consists of 18 students. The instruments in this study consisted of observation sheets, student worksheets, and critical thinking skills test sheets. From the results of the study it was found that the critical thinking skills of students showed an increase in each cycle with the application of the Project Based Learning model. Thus it was concluded that this Classroom Action Research was categorized as reaching the target in the second cycle.

Penentuan Fasies Sentral Gunung Api Purba Menggunakan Metode Gravitasi Pada Kawasan Gunung Ijo, Pegunungan Kulonprogo

The Kulon Progo Mountains are a range of Old Volcanoes that are no longer active so that the body is difficult to identify as a volcano body. One of the old volcanoes in the Kulon Progo Mountains is Mount Ijo. The description of the subsurface through the characteristics of the existence of ancient volcanoes uses a geophysical method approach, namely the gravity method with supporting data in the form of geological studies of the Mount Ijo area. This is done to get the distribution of variations in the subsurface gravity field of Mount Ijo. The gravity data used is GGMPlus gravity satellite data with a lot area of 8.32 x 14.23 Km with a point distribution of 2368 points. In the processing process, a derivative analysis is carried out using Total Horizontal Derivative (THD) and Total Derivative (TDR). The results obtained from the ABL value of the Mount Ijo area illustrate the distribution of gravity anomaly values with high values ranging from 0.2 mGal to 3.5 mGal in the center of the map indicating the presence of the peak of Mount Ijo which is the central facies of Mount Ijo. Supported by the presence of structures in the form of faults and intrusion hills included in the proximal facies surrounding the central facies. The 2.5-dimensional model of the 2 incisions of the residual anomaly map has a depth of 800m and produced a picture of the central facies, proximal facies and a small part of the medial facies of Mount Ijo.
