Abstract

Based on data from the Ministry of Education and Culture that as many 646.200 schools were closed due to the covid-19. So, Indonesia had to do distance learning. Therefore, this study aims to determine the effectiveness of distance learning in chemistry learning at Serang Regency State High School. To achieve these objectives, researchers used descriptive methods using quantitative data analysis. Using data collection techniques in the form of questionnaires for teachers and students, interviews, and documentation with a total sample of 120 people. The results showed that the effectiveness of distance learning on the Chemistry Teacher questionnaire in five schools in Serang Regency had a percentage of 86.51% with a very effective category. The effectiveness of distance learning on the questionnaire. Students in five schools in Serang Regency have a percentage of 67.30 in the effective category. This is in accordance with the results of the chemistry scores obtained by students for one semester with an average value of 83 in the high category. So, in general, the disctace learning process for chemistry subjects at Serang Regency State High School has a percentage of 76,9% or runs effectively.

Abstract

This research aims to determine the effect of the Chemopoly learning media on increasing the learning motivation of class Students feel bored and dissatisfied with the delivery of material or giving assignments conventionally, especially when the chemistry subject is in the last class period. By implementing the Chemopoly learning media, students' learning motivation increases in chemistry subjects. Apart from that, Chemopoly learning media also increases understanding of concepts in the material provided by the teacher. The method used in this research is qualitative method. The type of research used is a qualitative descriptive approach. The research was conducted at SMA Negeri 8 Serang City with research subjects of class XII IPA 2 students totaling 37 students. The data collection techniques used are, observation, questionnaires and documentation. The research results showed that students' learning motivation increased after implementing the Chemopoly learning media. Students feel that learning chemistry is more fun and less monotonous after using Chemopoly learning media. Students also want the Chemopoly learning media to be applied to other subjects so that learning no longer uses conventional methods.

Abstract

This research focuses on Natural Science learning, especially colloid material, where teaching is still dominated by the lecture method. Learning models that encourage students to make direct observations through experiments are rarely applied. This causes students to be less trained in solving problems, so their critical thinking skills are not optimally developed. This study aims to determine the effect of STEM (Science, Technology, Engineering, and Mathematics) learning model on students' critical thinking skills on colloid material at SMA Negeri 1 Telaga. The research design used was pre-experiment with one group pre-test post-test design. The research sample consisted of 29 students selected by census/total sampling. Data collection was done through critical thinking skills test. The results showed that the average percentage of students' critical thinking skills in the pre-test was 46.11%, which was in the medium category, and in the post-test it increased to 83%, which was in the very high category. This shows that the STEM learning model can improve students' understanding and critical thinking skills. The statistical test shows a significance value of 0.000 < 0.05, which means H1 is accepted and H0 is rejected. Thus, it can be concluded that the STEM learning model has a positive influence on students' critical thinking skills.

Abstract

The 21st century demands that students develop various skills, including critical thinking. This study investigates how effective an interactive video-assisted Problem-Based Learning (PBL) model is in enhancing students' critical thinking skills on the topic of atomic structure and the benefits of nanomaterials. The research used a quasi-experimental design with non-equivalent control groups. The sample was selected using cluster random sampling, with class X4 as the experimental group and class X6 as the control group. Data were collected through pre-tests and post-tests, which were analyzed using the product-moment correlation formula to validate the test instruments. The results showed that the experimental group's average post-test score for critical thinking skills was 75.944, higher than the control group's score of 61.278. The hypothesis test using an independent sample t-test revealed a Sig (2-tailed) value of 0.000, which is less than 0.05, indicating that the alternative hypothesis (Ha) is accepted and the null hypothesis (H0) is rejected. Additionally, the effectiveness of the model was assessed using the n-gain test, resulting in a mean value of 0.6327, which falls into the medium effectiveness category.

Abstract

This research investigates the impact of the Contextual Teaching and Learning (CTL) model on critical thinking abilities and student character in the reaction rate topic at SMA Negeri 3 Gorontalo Utara. This research employs a quantitative methodology with a near-experimental design, specifically employing a one-group pre-test and post-test design. Data were gathered through questionnaires and tests. The study's population consisted of grade XI students at SMA Negeri 3 Gorontalo Utara throughout the opening term of the academic cycle for 2024-2025. A total sampling method was used, selecting 50 students from two classes who enrolled in chemistry specialization. The findings indicate that the application of the CTL model led to an improvement in critical thinking skills, with the experimental class showing a mean pre-test result of 37.56% and a post-test result of 84.22%, whereas the replication group recorded pre-test and post-test averages of 37.33% and 83.89%, respectively. As for character growth, the experimental group displayed an average score of 80.13%, while the replication group showed 79.90%. Both classes demonstrated significant progress, as shown by the consistency of the results in both groups. The outcomes of the paired sample t-test reveal a noteworthy value of 0.000 < 0.05, prompting the dismissal of H0 and the endorsement of Ha, confirming that the CTL model positively affects critical thinking skills and student character in reaction rate material.
