Abstract

Penelitian ini bertujuan untuk menentukan efektivitas e-komik interaktif hidrokarbon terhadap keterampilan berpikir kritis peserta didik fase E di SMTI Padang. Penelitian ini menggunakan metode eksperimen semu (Quasi Experimental Design) dengan desain Pretest-Posttest Control Group Design. Sampel penelitian terdiri atas kelas X.4 TKI sebagai kelas eksperimen dan kelas X.5 TKI sebagai kelas kontrol yang masing-masing berjumlah 35 peserta didik. Peneliti mengumpulkan data menggunakan tes keterampilan berpikir kritis dan menganalisisnya dengan uji N-gain, uji normalitas, uji homogenitas, dan uji hipotesis. Hasil penelitian menunjukkan bahwa kelas eksperimen memperoleh nilai N-gain sebesar 0,80, sedangkan kelas kontrol memperoleh nilai 0,75 dengan kategori tinggi. Hasil uji hipotesis menunjukkan bahwa thitung (2,278) > ttabel (1,668), sehingga H₀ ditolak. Peserta didik mencapai kategori sangat tinggi pada indikator elementary clarification (98,28%), basic support (85,71%), inference (90,71%), dan advanced clarification (88,58%), serta kategori cukup tinggi pada indikator strategy and tactics (57,14%). Penelitian ini menyimpulkan bahwa e-komik interaktif hidrokarbon efektif meningkatkan keterampilan berpikir kritis peserta didik.

Abstract

Active participation of students is one of the important aspects in improving the understanding of chemical concepts. This research is a Classroom Action Research that aims to increase the active participation of students in class X SMA PGRI 1 Padang through chemical element card media on electron configuration material and periodic table of elements. This research was conducted in two cycles which included the stages of planning, action implementation, observation, and reflection. Data were collected using observation sheets with physical and psychological indicators. The results showed an increase in students' active participation from 64.42% in cycle I to 86.95% in cycle II. Rewards proved to be effective in increasing students' active participation

Abstract

Chemical literacy is a crucial 21st-century competence; however, its assessment instruments, particularly for buffer solution topics, remain limited. This Research and Development (R&D) study utilizing the Rasch model was conducted to develop a chemical literacy test instrument in support of SDGs 4: Quality Education. The test was developed from eight initial items and piloted on 72 senior high school students. Data analysis techniques included the Content Validity Index (CVI) and Ministeps software analysis. The content validity results yielded a CVI value of 0.96 (valid), and empirical analysis demonstrated that all eight items satisfied the item fit criteria. The instrument demonstrated a Cronbach's alpha of 0.83 (good), person reliability of 0.78 (fair), and item reliability of 0.90 (good). These data indicate an excellent person-item interaction, moderately stable student responses, and high instrument reliability. The item separation value (2.99) classified the item difficulty into four strata, while the person separation value (1.91) grouped student abilities into three strata. Although this instrument provides comprehensive psychometric quality to support SDGs 4 targets and assists teachers in measuring students' chemical literacy, future research is recommended to modify the instrument by incorporating more complex and challenging items to capture a broader spectrum of student abilities.

Abstract

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.

Abstract

This study aims to analyze the effect of implementing the TPACK approach with the help of hydrocarbon e-modules on students' critical thinking skills at SMAN 3 Lubuk Basung. The research method used is a quasi-experiment with a non-equivalent control group design. The population consists of 41 students of class XI MIPA 1 and XI MIPA 2 of SMAN 3 Lubuk Basung in the 2023/2024 academic year. Samples were taken from the entire population by sampling using a saturated sampling technique. The research instrument was in the form of test questions arranged based on indicators of critical thinking skills. The results of the data analysis showed normal and homogeneous data and the hypothesis test showed tcount> ttable so that H0 was rejected and H1 was accepted. In other words, the implementation of the TPACK approach with the help of hydrocarbon e-modules can improve the critical thinking skills of class XI students at SMAN 3 Lubuk Basung.
