Abstract

Penelitian ini dilatar belakangi dari kurangnya penggunaan modul di SMP Negeri 5 Botomuzoi, kurangnya respon peserta didik dalam pembelajaran sehingga kurang aktif menjawab pertanyaan dari guru, dan pembelajaran berpusat pada guru. Penelitian ini bertujuan untuk mengembangkan modul berbasis contextual teaching and learning pada mata pelajaran IPA kelas VIII yang layak secara empiris. Kelayakan modul diperoleh melalui validasi ahli materi dan guru untuk menilai kelayakan isi dan materi modul, ahli bahasa untuk menilai kelayakan penyajian modul, ahli desain untuk menilai kelayakan desain modul, kepraktisan peserta didik dan efektivitas modul dalam pembelajaran. Penelitian ini merupakan penelitian pengembangan menggunakan model pengembangan ADDIE yang terdiri dari lima tahap Analyze, Design, Development, Implementation, Evaluation. Namun pada penelitian ini tahap evaluation tidak dilakukan. Prosedur pengembangan dimulai dari tahap; (1) analisis masalah, (2) perancangan modul, (3) validasi dan uji coba modul. Instrument yang digunakan adalah lembar penilaian kelayakan modul, angket respon untuk peserta didik dan efektivitas modul. Data validasi dan angket kepraktisan modul telah peroleh dan dianalisis secara deskriptif kualitatif. Kelayakan modul IPA SMP kelas VIII berbasis contextual teaching and learning yang telah dikembangkan dan dinilai oleh ahli materi, ahli bahasa, ahli desain mencapai skor 4,0 (sangat layak). Kepraktisan modul berbasis contextual teaching and learning yang telah dikembangkan menurut penilaian peserta didik pada uji coba perseorangan, uji coba kelompok kecil dan uji lapangan mencapai tingkat presentase 100% (sangat praktis). Dan Efektivitas modul IPA berbasis contextual teaching and learning mencapai presentase 85% (sangat efektif)

Abstract

The low motivation and learning outcomes of students in mathematics learning require innovative, contextual learning models. This study aims to determine the effect of the Contextual Teaching and Learning (CTL) model on students’ motivation and natural science learning outcomes. An experimental method with a randomized control-group pretest–posttest design was applied to 67 eighth-grade students of SMP Negeri 1 Namohalu Esiwa, who were divided into experimental and control classes. The instruments consisted of essay tests and motivation questionnaires that had been tested for validity and reliability. The results showed that the average learning motivation in the experimental class increased from 66.03 (moderate category) to 80.7 (good category), while learning outcomes increased from 62.83 (moderate) to 85.35 (good). Based on the two-tailed t-test, the calculated t-value was 9.8566 for the motivation variable and 9.2406 for the learning outcomes variable. Both values exceeded the t-table value at the 0.05 significance level, indicating that the null hypothesis was rejected. Thus, the CTL model has a significant effect on improving motivation and mathematics learning outcomes.

Abstract

This study aims to analyze the effectiveness of the cooperative learning model Group Investigation in improving students’ interest and learning outcomes in Biology. The research employed a Classroom Action Research (CAR) design conducted in two cycles, involving 21 students of grade XI. Each cycle consisted of planning, action, observation, and reflection stages. Data were collected using observation sheets, questionnaires, tests, and interviews. The results showed a significant improvement in the learning process, students’ interest, and cognitive achievement. In Cycle I, students’ active participation reached 59.23%, which increased to 85.57% in Cycle II. Students’ learning interest also improved from 69.83% (moderate category) to 86.76% (very good category). In terms of learning outcomes, the average score increased from 68.70 in Cycle I to 80.10 in Cycle II, while classical completeness improved from 61.90% to 85.71%. These findings indicate that the implementation of the Group Investigation model effectively enhances both affective and cognitive aspects of learning. Therefore, this model is recommended as an innovative strategy to create an interactive and student-centered Biology learning environment.

Abstract

Low student motivation and poor science learning outcomes at the junior high school level have remained persistent challenges, particularly when classroom instruction has been dominated by conventional approaches that fail to actively engage students. This study aimed to analyze the effectiveness of the Think Pair and Share (TPS) cooperative learning model in improving the motivation and science learning outcomes of seventh-grade junior high school students on the topic of Ecosystems. The study employed a Classroom Action Research (CAR) approach based on the Kemmis and McTaggart model, conducted in two cycles consisting of planning, action, observation, and reflection stages. The research subjects were 26 seventh-grade students of SMP Negeri 5 Namohalu Esiwa. Data were collected through classroom observation, learning motivation questionnaires, achievement tests, and interviews, then analyzed using descriptive quantitative and qualitative techniques. The findings revealed that the implementation of TPS significantly improved the quality of the learning process, student motivation, and learning outcomes. Student participation increased from 72.22% in Cycle I to 94.27% in Cycle II, learning motivation rose from 73.50% to 93.13%, while the average learning achievement score improved from 70.02 to 85.04, with classical mastery reaching 92.31%. These findings demonstrate that TPS was effective in creating interactive, collaborative, and meaningful science learning experiences.
