<![CDATA[This study aimed to analyze the effectiveness of the atomic structure module based on guided discovery learning integrated with TPACK on improving the chemical literacy skills of phase E students in high school. The research applied the type of quasi-experiment with pretest-posttest control group design. The population includes phase E students of class X SMAN 1 Sungai Penuh who are studying chemistry in the 2024/2025 academic year, as many as seven classes. Samples were taken using a purposive sampling technique, and the experimental class X.D and control class X.F were selected. Chemical literacy test instrument in the form of essay questions. The data obtained were analyzed using the n-gain test and hypothesis testing with the 't' test. The results of data analysis obtained the n-gain value of the control class and experimental class, respectively, 0.20 in the low category and 0.35 in the medium category. The hypothesis test results obtained tcount > ttable, which is 3.43> 2.009. The chemical literacy ability of the experimental class is significantly higher than that of the control class.

<![CDATA[This study aims to analyze the validity, practicality, and effectiveness of the acid-base e-module based on guided discovery learning on students' digital literacy skills. The development model used is the Plomp development model. The developed e- module was validated by three lecturers and two chemistry teachers. The module's practicality test was carried out by three chemistry teachers and 33 high school students. The module's effectiveness test was carried out using the pre-experimental method with a non-equivalent control group design. The validity test is explained using Aiken's V formula. The overall validity test results were obtained of 0.91 with a valid category. The results of the e-module practicality test carried out by teachers and students were 89.4 and 87.09% with a very practical category. The average N-Gain value in the experimental class was 0.75, which is in the high category. Based on the results of data analysis, it can be concluded that the acid-base e-module, based on guided discovery learning that was developed, is valid, practical, and effective in improving the digital literacy skills of Phase F (Grade XI) high school students]]>

<![CDATA[This study aims to analyze student learning outcomes in chemical bonding material and analyze the factors that influence low student learning outcomes. The type of research conducted is descriptive research. The subjects of the study were students of phase F3 class XI SMAN 12 Padang in the semester July-December 2024. The sample determination was carried out using a purposive sampling technique. The instrument used was a two-tier diagnostic test of 15 questions. Data obtained from the analysis of student learning outcomes in chemical bonding material showed that 36.7% of students had not reached the KKTP where there were several learning objectives that had not been achieved by students, namely determining the process of forming single, double and triple bonds, then on the learning objective of distinguishing polar and non-polar covalent bonds, then on the learning objective of determining the formation of coordinate covalent bonds in several compounds. The causes of low student learning outcomes were caused by internal and external factors, but external factors were more dominant in causing low student learning outcomes.

<![CDATA[The limited number of studies on the implementation of the cooperative learning model Team Games Tournament (TGT) in the context of chemistry education serves as the background for this research, particularly in addressing the issues of low student engagement and learning outcomes, which affect the overall effectiveness of classroom instruction. This study aims to improve the learning outcomes and engagement of Grade XI students on the topic of reaction rate through the application of the TGT cooperative learning model. The method used was Classroom Action Research (CAR), conducted in two cycles involving 35 students from Class XI Chemistry 4 at SMAN 3 Padang Panjang, selected through purposive sampling. Data were collected through observations of learning activities during instruction and learning outcome tests administered at the end of each cycle. The data were analyzed using descriptive qualitative and quantitative methods. The findings show a significant improvement in student learning outcomes, with classical completeness increasing from 69% in the first cycle to 86% in the second, and student engagement rising from 54% to 77%. These results indicate that the TGT model is effective in enhancing both student achievement and active participation, aligning with cooperative learning theory, which emphasizes the role of social interaction and constructive competition in fostering motivation and conceptual understanding. This study contributes to the development of enjoyable and meaningful chemistry teaching strategies and recommends TGT as a promising alternative for increasing student involvement and achievement, while also encouraging further research on this model across different topics and educational levels.]]>

<![CDATA[The development of digital technology has significantly impacted the field of education, particularly in the creation of interactive and contextual learning media. This study aims to determine the effectiveness of a molecular shape module integrated with Augmented Reality (AR) in enhancing the digital literacy skills of Phase F high school students. A quasi-experimental method was employed using a Nonequivalent Control Group Design. The study population included all Phase F high school students, with sample selection conducted through purposive sampling. The results indicate that the AR-based module is effective in improving students’ digital literacy, as evidenced by an N-gain score of 0.683 in the experimental class, categorized as moderate. Supporting data from teacher observation sheets and digital literacy questionnaires showed an average achievement of 86.26%, classified as effective. The results of the independent sample t-test revealed a significance value (2-tailed) of less than 0.05, indicating a significant difference between the experimental and control classes. Therefore, the AR-integrated molecular shape module is proven to be effective in enhancing students’ digital literacy and contributes to the advancement of technology-based learning that is innovative and responsive to contemporary educational needs.]]>
