Abstract

This study aims to improve students' mathematics learning outcomes through the implementation of cooperative learning model using the Think Pair Share (TPS) technique. The subjects of the study were the students of class VII-A at SMPN 3 Surabaya. This Classroom Action Research (CAR) was conducted in two cycles, each consisting of planning, implementation, observation, and reflection stages. Data were collected through tests, namely formative tests and post-tests. The results showed a significant improvement in students' mathematics learning outcomes after the application of the Think Pair Share technique. In the first cycle, the average student scores increased significantly compared to before the intervention, with even greater improvements observed in the second cycle. Besides improving learning outcomes, the application of the Think Pair Share technique also had a positive impact on student participation and interaction during the learning process. Students became more active in discussions and helped each other understand the lesson material. Therefore, the Think Pair Share technique has proven effective in enhancing the mathematics learning outcomes of students in class VII-A at SMPN 3 Surabaya. .

Abstract

The simplest gas and approaching the simplest properties of a true gas is an ideal gas. Ideal gases satisfy the ordinary gas equation, while real gases do not always satisfy the ideal gas equation. Gas laws such as Boyle's Law, Charles' Law, and Gay Lusaac's Law, show the relationships between macroscopic units of various processes and formulations.This research is a type of literature review research by looking for theoretical references that are relevant to the cases or problems found.The results of Boyle's experiments stated that if the temperature of a gas in a closed vessel is kept constant, the gas pressure will be inversely proportional to its volume. Gay-Lusaac's law states that the volume of gas in a closed vessel is maintained constant, the gas pressure will be proportional to its absolute temperature. Charles's law states that at constant pressure, the volume of an ideal gas of a certain mass is directly proportional to its temperature. An ideal gas is a concept in physics which assumes that a gas consists of very small particles with zero volume, do not interact with each other, and move randomly in a closed container. This concept also assumes that collisions between gas particles and the walls of the container are elastic, meaning that kinetic energy is maintained in each collision.

Abstract

This research aims to determine the learning independence of class III students at SDN 167 Pekanbaru in mathematics learning before and after using inquiry strategies. This research is classroom action research using the Kemmis and Taggart method, namely (plan, action, observation and reflection). This research consists of 2 cycles, each with 2 meetings. Data collection techniques use observation, field notes and documentation. Data analysis uses quantitative and qualitative. Research results: In the Pre-Cycle, most students were in the Less Independent category. Entering Cycle I, there is a clear improvement. The number of students in the Sufficiently Independent category has increased, but there are still students in the Less Independent category. In Cycle II, the most striking changes occurred. The number of students in the Very Independent category increased significantly. This shows that the majority of students now have a high level of independence, with great achievements in increasing their independence compared to the previous cycle.

Abstract

This study aims to review various methods and applications of the ethnochemistry approach in chemistry education through a literature review. Ethnochemistry connects chemical concepts with local wisdom and culture, providing deeper contextualization for students. The literature review was conducted by collecting data from various articles relevant to this topic, published between 2018 and 2024. The review results indicate that integrating ethnochemistry into chemistry learning can enhance students' understanding of chemical concepts, scientific skills, creativity, and engagement. This approach also helps preserve traditional chemical knowledge that may otherwise be lost. This study concludes that ethnochemistry is a significant innovation that can improve the quality of chemistry education in a more meaningful and relevant way for students, while also strengthening their cultural identity.

Abstract

This study was conducted by looking at the low learning outcomes of class X-2 students at SMA Negeri 9 Surabaya in the previous material, namely SPLTV. This study was conducted with the aim of improving students' mathematics learning outcomes in the quadratic equation material by implementing a cooperative learning model of the team games tournament (TGT) type using the help of wordwall. This study is included in classroom action research which is carried out in two cycles. The subjects of the study used were 36 class X-2 students at SMA Negeri 9 Surabaya. The research data were obtained through pretest, observation, and posttest. The analysis data from the pretest and posttest results were in the form of quantitative data which would be used to determine the increase in student learning outcomes. While the analysis data from the observation results in the form of qualitative data were used as a guideline to improve and perfect learning activities from cycle I to cycle II. Based on the results of the study that has been carried out, it shows that implementing a cooperative learning model of the team games tournament (TGT) type using the help of wordwall on the quadratic equation material can improve the learning outcomes of class X-2 students at SMA Negeri 9 Surabaya. The classical completeness of the pretest cycle I was 44.4%. After the implementation of the TGT type cooperative learning model, there was an increase to 77.8% in the posttest of cycle I. In cycle II, it increased again to 94.6% with a classical completion target of 85%.
