Abstract

This study aims to develop students' abilities in interpreting and making reasoning about physics data. The type of research used is experimental research. Physics learning was carried out in two classes: control and experimental groups. In the experimental group, physics learning was oriented to student activities where students dealt with physics objects. In contrast, in the control group, physics was taught conventionally by applying direct learning. The ability to interpret and to make reasoning about data was obtained through written tests conducted on pre-test and post-test. Analysis of research data was carried out by qualitative descriptive and t-test statistical analysis. The descriptive analysis was performed to describe students' abilities to interpret and to make reasoning about data. A statistical t-test analysis was conducted to determine the difference in the impact of treatment on the two groups. The results showed that the average ability to interpret data and to make reasoning about data in the experimental group was 76.91 and 76.99, respectively, while in the control group, it was 53.33 and 63.08, respectively. The results of the t-test analysis showed that the 2-way (t-tailed) significance value was 0.000 < 0.05, so it could be stated that there was a difference in ability between the control group and the experimental group. Based on the results of these studies, it can be noted that learning physics that involves a lot of student activities that interact directly with physics objects can improve the skills of high school students in interpreting and reasoning scientific data.

Abstract

This study investigates the relationship between COVID-19 and weather conditions in six regions in Indonesia, namely South Jakarta, East Jakarta, North Jakarta, Jember Regency, Semarang City, and West Pasaman Regency. The study uses the daily number of positive cases of COVID-19 and weather data. Weather parameters used in this study are the average, maximum, and minimum temperature, rainfall, and relative humidity. Weather data were obtained from surface observation of Agency for Meteorology, Climatology and Geophysics (BMKG) and reanalysis product (ERA-5) from European Centre for Medium-Range Weather Forecasts (ECMWF). The effect of weather conditions on the number of COVID-19 cases was evaluated using the Spearman and Kendall correlation. It was found that the number of positive cases of COVID-19 had a relationship with weather parameters. A negative correlation was found between the temperature and the number of positive COVID-19 cases. Thus, the number of positive COVID-19 cases increases when the temperature decreases. On the other hand, rainfall and relative humidity positively correlate to the number of positive cases of COVID-19, which means that when the rainfall and relative humidity increase, the number of positive cases of COVID-19 increases. The relationship between weather conditions and the number of COVID-19 cases is more apparent in areas with a higher population density, such as Jakarta. The results of this study can be valuable information in handling COVID-19 cases.
