Assessing Pre-Service Science Teachers’ Understanding of Global Warming through the Content Representation (CoRe) Instrument

Meili Yanti — 2025-09-29

This study evaluates pre-service science teachers’ conceptual understanding of global warming using the Content Representation (CoRe) instrument. A descriptive design was employed with purposive sampling of second-year science education students. Data were gathered through eight CoRe prompts eliciting essential concepts, rationales, instructional sequencing, student considerations, decision factors, assessment strategies, and anticipated challenges. Responses were scored with a four-level rubric to derive profiles of strengths and weaknesses. Findings indicate overall understanding at a medium yet tending-to-low level; participants could identify core ideas and justify relevance, but struggled to organize coherent conceptual sequences, connect student context to instructional decisions, and articulate specific indicators of understanding. These results underscore the need to strengthen mechanism-based content knowledge, assessment literacy for conceptual understanding, and evidence-informed practice through microteaching and data-analysis tasks. The study recommends integrating CoRe as a structured reflection tool within teacher education curricula.

Evaluasi Literasi Membaca Al-Qur’an di SMK Negeri 42 Jakarta Menggunakan Model CIPP

Muhamad Heru Hermawan — 2025-09-29

Penelitian ini bertujuan untuk mengevaluasi pelaksanaan program ekstrakurikuler Baca Tulis Al-Qur’an (BTQ) di SMK Negeri 42 Jakarta dalam upaya meningkatkan literasi Al-Qur’an siswa. Evaluasi dilakukan menggunakan model CIPP (Context, Input, Process, Product) yang dikembangkan oleh Stufflebeam, untuk menilai secara komprehensif aspek relevansi program, sumber daya, pelaksanaan kegiatan, dan capaian hasil belajar siswa.

Penelitian ini menggunakan pendekatan kualitatif dengan jenis penelitian evaluatif. Teknik pengumpulan data dilakukan melalui observasi, wawancara mendalam, dan studi dokumentasi terhadap dokumen sekolah. Informan penelitian terdiri dari wakil kepala sekolah, guru pembimbing BTQ, serta siswa peserta program. Hasil penelitian menunjukkan bahwa program BTQ telah direncanakan dengan baik dan memiliki dasar hukum yang memadai, meskipun belum dilengkapi dengan panduan teknis yang baku. Dari aspek input, sarana dan prasarana masih terbatas, serta kurikulum belum terstandar. Proses pelaksanaan berjalan cukup konsisten, namun menghadapi kendala seperti keterbatasan waktu dan variasi kemampuan siswa. Dari sisi produk, program ini terbukti meningkatkan kemampuan dasar membaca dan menulis Al-Qur’an serta membentuk sikap religius siswa, meskipun sistem evaluasi formal masih perlu ditingkatkan. Penelitian ini merekomendasikan penguatan kurikulum, pelatihan guru, serta penyediaan sarana pembelajaran dan sistem evaluasi yang terstruktur untuk meningkatkan efektivitas program BTQ secara berkelanjutan.

The Validity Analysis of the STEM-Based Biotechnology E-Book to Enhance Students’ Creative Thinking Ability and Skills in Producing Innovative Works

This study aims to develop and validate a STEM-based Biotechnology E-Book designed to enhance students’ creative thinking abilities and skills in producing innovative works. The research method employed was Research and Development (R&D), consisting of stages including needs analysis, design, product development, and expert validation. The instrument used was a validation sheet covering aspects of content, language, presentation, and graphics. Data were analyzed using descriptive percentage techniques by calculating the Mean Score Percentage (MSP) and interpreting the results according to validity criteria. The findings indicate that the STEM-based Biotechnology E-Book meets the “very good” category in nearly all validated aspects. The content aspect achieved an average MSP of 96.48%, the language aspect 98.21%, the presentation aspect 95.3%, and the graphic aspect 96.4%. All indicators fell within the valid category, with only a few components rated as “good.” These results affirm that the developed e-book possesses material quality aligned with the Learning Outcomes (CPL) and Course Learning Outcomes (CPMK), employs appropriate and motivational language, provides systematic presentation, and features visually appealing and proportional graphics. Based on these findings, it can be concluded that the developed STEM-based Biotechnology E-Book is feasible to be used as an alternative learning medium in the Biotechnology course. This product has the potential to support the enhancement of students’ creative thinking skills and innovative abilities. Further research will be conducted to examine the effectiveness and practicality of the product more broadly in testing students’ creative thinking and innovative skills.
