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

Students need to be able to think critically in order to meet the challenges of the 21st century. Be that as it may, the decisive reasoning abilities of understudies are still somewhat low. The RADEC model is a learning model that can aid in the development of critical thinking abilities. The goal of this study is to find out how well the RADEC model helps students in high school think critically about colloidal materials. This study employs experimental, quantitative research techniques. The populace is all understudies in class XI MIPA at SMAN 5 Samarinda. The examples were understudies from class XI MIPA 2 and XI MIPA 4 at SMAN 5 Samarinda, adding up to 75 individuals. The exploration test was chosen utilizing a group irregular inspecting strategy. One-group pre-test post-test design was utilized in the research design. Information assortment involves tests as pre-tests and post-tests, educator and understudy movement perception sheets, and understudy reaction surveys. Statistical tests were conducted first, including the N-Gain test and the effect size test, for data analysis. According to the findings of the research, the RADEC model meets the effective criteria in terms of students' responses to learning based on the RADEC learning model and their increased critical thinking abilities. The findings of the research lead us to the conclusion that the RADEC model works to improve students' critical thinking abilities.

Abstract

This research aims to understand how the implementation of the independent learning curriculum is applied in the chemistry learning process and to determine the effectiveness of this curriculum's application in the chemistry learning process. The sample for this research is Class X.1 which consists of 30 students and 4 chemistry teachers who are the subjects of this research. Data collection was carried out by distributing questionnaires to chemistry teachers to understand how the independent learning curriculum is applied in the chemistry learning process and by administering a posttest to students to determine the effectiveness of the curriculum's application in the chemistry learning process. This research uses descriptive statistical analysis. The results of the descriptive statistical analysis of the questionnaire on the application of the independent learning curriculum obtained an average score of 81.75 with very good criteria, and the results of the descriptive statistical analysis of student learning outcomes obtained an average score of 78.1 with satisfactory criteria. Based on these analysis results, it can be concluded that the implementation of the independent learning curriculum in the chemistry learning process in class X.1 at SMAN 9 Makassar has been very well applied and the effectiveness of the independent learning curriculum in the learning process in class X.1 at SMAN 9 Makassar has been effective.

Abstract

Chemistry is often considered a difficult subject for learners due to its abstract concepts and complex terminology. This can lead to difficulties in understanding the material and a decrease in students' interest in studying chemistry. The aim of this research is to describe and explain the factors of difficulty understanding in solving chemistry material experienced by students. The research method used is descriptive qualitative. The results show that 62.3% of students experience slight difficulty and 37.7% experience moderate difficulty in understanding chemistry material. The interest in learning chemistry of class XII MIA students is categorized as sufficient with a percentage of 46.68%. Factors causing difficulties in understanding chemistry material include a lack of understanding of mathematical concepts, the predominance of lecture methods, limited learning media, and the suboptimal use of chemistry laboratories. The conclusion of this research provides an overview that the factors causing difficulties in understanding chemistry material affect students' interest in learning. Therefore, these findings can be used as evaluation material to improve the quality of chemistry education in schools.

Abstract

This research was conducted to determine the changes in conceptual thinking creativity in hydrocarbons among students who were taught by using the Hyperdocs Worksheet at SMA Negeri 7 Gorontalo on hydrocarbon material. The method used in this research was a quasi-experiment with a non-equivalent control group design. The research samples consisted of students from class XI Merdeka 1 as the experiment group and XI Merdeka 2 as a control group at SMA Negeri 7 Gorontalo, selected using purposive sampling. The research from the creative thinking ability test were statitically processed, including prerequisite test consisting of normality and homogeneity tests. The result showed normal distribution and homogeneity. The average pre-test score for the experimental class was 31% and the post-test score was 82%, while the control class had an average pre-test score of 28% and a the post-test score 60%. Furthermore, based on the hypothesis testing using a t-test at a significance level of α = 0.05, a tcount was 9.25 with a ttable of 1.671. This indicates that tcount > ttable, leading to the conclusion that H0 is rejected and H1 is confirmed, indicating a change in conceptual thinking creativity hydrocarbons among students taught using by modeling Hyperdocs Worksheets modeling. The results of the N-Gain test showed that the average N-Gain score for the experiment class was 0.73 and that for the control class, it was 0.43, indicating a high N-Gain score in the experimental class. Therefore, using Hyperdocs Worksheets modeling effectively enhances students' creativity in thinking about hydrocarbon concepts.
