Abstract

Teachers almost never carry out learning that is oriented towards higher order thinking skills (HOTS). The author also rarely uses learning media. As a result, the learning atmosphere in the classroom is stiff and the children don't look cheerful. .based on the results of interviews with several students, information was obtained that (a) students were lazy to attend lessons that were mostly carried out by the teacher by means of lectures (b) apart from lectures, the method that was always used by the teacher was assignments or homework (PR). Some students claim to be bored with tasks that are only theoretical. To face the Industrial Revolution 4.0 era, students must be equipped with higher-order thinking skills. One of the HOTS-oriented learning models and suggested in the implementation of the 2013 Curriculum is the Discovery Learning learning model. Discovery learning is a learning process that occurs when students are not presented with information directly but students are required to organize their understanding of that information independently. After carrying out the mathematics learning model of Discovery Learning, the authors found that the learning processes and results of students increased. Better than previous studies. When the Discovery Learning model was applied to other VIII graders, it turned out that the students' learning processes and outcomes were just as good. Discovery Learning learning practices that work well, the authors conclude as a HOTS-oriented learning best practice with the Discovery Learning model.

Abstract

Non-communicable diseases (NCDs) have become a significant health issue at both national and global levels. The increasing prevalence of NCDs is closely related to dietary habits that include high cholesterol intake. Excessive cholesterol in the body can lead to various complications, such as heart disease, stroke, and hypertension. Therefore, this outreach aims to educate and enhance public knowledge regarding the complications caused by high cholesterol and preventive measures that can be taken. The outreach activities were conducted face-to-face, involving active participation from the participants. The methods used in the outreach included presentations, interactive discussions, and Q&A sessions to ensure better understanding of the topic. Data were collected through pre-tests and post-tests conducted before and after the outreach. Data analysis using the Shapiro-Wilk test showed p < 0.05 for both pre-tests and post-tests, indicating that the data were not normally distributed (P > 0.05). Further analysis using the Wilcoxon test indicated a significant change in participants' knowledge before and after the outreach, with a p-value < 0.05. The results of this outreach are expected to have a positive impact on the public’s knowledge regarding health risks associated with high cholesterol and to encourage individuals to adopt healthier lifestyles. Thus, it is hoped that the prevalence of NCDs can decrease and the community will be more aware of the dangers of high cholesterol.

Abstract

This research is motivated by the low learning outcomes of students in Natural Sciences. This is because the learning model applied is not optimal and students are less interested in the learning process. Therefore, it is necessary to change the implementation of learning in the classroom by using the make a match learning model (finding card pairs) in the learning process. The formulation of the problem in this study is how the application of the make a match model can improve the learning outcomes of grade IV science at SD Negeri 200405 Hutaimbaru Jl. Sibolga, KM 4 Hutaimbaru, Kec. Hutaimbaru, Padangsidimpuan City, North Sumatra Province. This study aims to determine the application of the make a match model can improve the learning outcomes of grade IV science at SD Negeri 200405 Hutaimbaru Jl. Sibolga, KM 4 Hutaimbaru, Kec. Hutaimbaru, Padangsidimpuan City, North Sumatra Province. The type of this research is Classroom Action Research (CAR) at the planning, action, observation and reflection stages at SD Negeri 200405 Hutaimbaru. The data collection instruments used were tests and observations. The results of the study showed that the application of the make a match model can improve student learning outcomes. This is evidenced by the increase in the average value and completeness of student learning outcomes, namely in the pre-cycle an average of 53.7% and completeness of 13% (3 out of 24 students).

Abstract

Measures of central tendency, such as the mean, median, and mode, are fundamental concepts in statistics that can be used to support decision-making. The purpose of this study is to describe how university students reason about measures of central tendency when comparing two age distributions of patients presented in the form of frequency polygons, from a commognitive perspective. This study employs a descriptive qualitative method with an exploratory approach. A total of 37 students participated in the study, four of whom were selected as research subjects—two representing the calculative category and two representing the visual-interpretative category. The research instruments consisted of one problem related to measures of central tendency and an interview guide. The problem included three questions, each presenting data in the form of frequency polygons. The data were thematically analyzed using Sfard’s commognitive framework, focusing on four components: word use, visual mediators, routines, and narratives. The findings reveal that students in the calculative category predominantly used visual mediators and routines. In contrast, students in the visual-interpretative category emphasized the use of word use to construct narratives. Keywords: commognitive, reasoning, measures of central tendency, frequency polygon
