The use of learning media in science education is increasingly important to improve students' learning competence and motivation, yet there is still a gap in the understanding of the effectiveness of strategic media management. This study aims to explore the role of learning media management in improving students' competencies as well as understanding the influence of students' preferences for learning media on their learning motivation. This study used a quantitative design with a survey method. The sample consisted of 54 junior high school students in North Sumatra Province who were selected using the convenience sampling method. Data were collected through an online survey covering four main constructs: teachers' learning media management strategies, students' science competencies, students' preferences for learning media, and students' learning motivation. Data analysis was conducted using SmartPLS (V.4) software to test the validity and reliability of the research instruments and SPSS (V.26) to analyze the relationship between variables through multiple regression analysis (univariate; ENTER model). The results showed that effective management of learning media, especially in visualizing complex concepts, had a significant influence on improving the procedural aspects of students' competence, although the influence on conceptual understanding was still limited. In addition, students' preference for relevant, engaging, and contextualized media was shown to positively influence their motivation, especially in the aspects of active engagement and learning comfort. These findings highlight the importance of interactive and strategic media design and the need for teacher training in maximizing the use of learning media. The implications of this study include the development of educational policies that support the integration of student preference-based learning media and the increase of teachers' capacity to manage media effectively to improve student learning outcomes.

Penelitian ini bertujuan untuk menganalisis pengaruh pembelajaran fisika berbasis STEM terhadap kemampuan berpikir kritis siswa dengan menggunakan pendekatan meta analisis. Meta analisis merupakan metode penelitian yang dilakukan dengan cara mengumpulkan, menelaah, dan menganalisis berbagai hasil penelitian yang telah ada sebelumnya guna menerima atau menolak hipotesis yang diajukan dalam penelitian terkait. Tahap awal penelitian ini dimulai dengan menetapkan permasalahan utama, yaitu mengkaji pengaruh pembelajaran fisika berbasis STEM terhadap keterampilan berpikir kritis siswa. Selanjutnya, peneliti menentukan dan menyeleksi artikel yang relevan berdasarkan kriteria tertentu, yakni artikel yang memuat pengaruh pembelajaran fisika berbasis STEM dengan variabel moderator berupa kemampuan berpikir kritis, jenjang pendidikan, serta materi pembelajaran yang digunakan. Setelah proses seleksi dilakukan, tahap berikutnya adalah pengkodean data untuk memperoleh informasi tambahan yang diperlukan dalam menginterpretasikan hasil meta analisis secara lebih komprehensif dan sistematis. Langkah terakhir yaitu menghitung nilai effect size dari setiap penelitian yang dianalisis, kemudian mengelompokkannya ke dalam kategori berdasarkan variabel moderator yang telah ditentukan sebelumnya. Hasil penelitian menunjukkan bahwa penerapan pembelajaran berbasis STEM dalam pembelajaran fisika mampu meningkatkan kemampuan berpikir kritis siswa dengan kategori sangat tinggi. Selain itu, berdasarkan analisis jenjang pendidikan, diperoleh bahwa nilai effect size pada sekolah menengah atas lebih tinggi dibandingkan sekolah menengah pertama. Hal ini menunjukkan bahwa pembelajaran berbasis STEM lebih efektif diterapkan pada jenjang sekolah menengah atas, terutama pada materi usaha dan energi.

The purpose of this research is to find out factors that can affecting Junior High School Students' 4C Skills such as self-efficacy, learning motivation, liveliness, mathematical literacy, and scientific literacy can significantly influence students' 4C skills. This study is quantitative research using a survey method. In addition, the effect of each construct on the 4C skills is estimated through the Partial Least Square Structural Equation Model (PLS-SEM). The research results show that self-efficacy, scientific literacy, learning motivation and activeness have a significant effect on 4C skills. Mathematical literacy does not have a significant effect on 4C skills, but scientific literacy has a mediating effect on the relationship between mathematical literacy and 4C skills. Therefore, it is expected that students will further improve their skills in realizing the demands of globalization.

The development of science and technology in the 21st century requires skills for an individual to be able to compete, which are called 4C skills. Initial studies show that students' 4C skills still need to be improved. The physics e-module based on the orientation, identify, discussion, and engage in behavior model is an important aspect that supports improving students' 21st century skills. This research aims to determine the validity and practicality of e-modules. The instrument used to collect data was a validity and practicality test questionnaire. The physics e-module based on the orientation identify, discussion, decision, and engage in behavior can be used in the learning process. Judging from the results of validity and practicality, the physics E-module based on the orientation, identify, discussion, decision, and engage in behavior model to improve students' 21st century skills has valid and practical criteria with an average validity value (Aiken's value) of 0, 93 with valid criteria. The teacher's practicality score is 89.6% with very practical criteria and the students' practicality is 87.4% with very practical criteria. This means that e-modules can be applied to physics learning and in theory can improve students' 21st century competency abilities.
