Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran scramble dengan media crossword puzzle terhadap motivasi dan hasil belajar kognitif biologi siswa. Motivasi belajar merupakan proses yang memberi semangat belajar, dorongan, dan perubahan tingkah laku dalam belajar. Hasil belajar merupakan skor yang menunjukkan tingkat pemahaman siswa. Penelitian ini dilakukan selama sekitar satu bulan. Jenis penelitian ini merupakan penelitian eksperimen dengan pretest-posttest control group design. Populasi berjumlah 60 siswa, sampel diambil menggunakan teknik simple random sampling. Sampel berjumlah 20 siswa kelas VIII-A sebagai kelas eksperimen dan 20 siswa kelas VIII-B sebagai kelas kontrol. Pengumpulan data menggunakan instrumen tes berupa pretest-posttest berbentuk pilihan berganda sebanyak 20 soal dan instrumen non tes berupa angket motivasi belajar yang meliputi delapan indikator motivasi belajar yang terdiri dari 20 soal. Data yang telah didapatkan dianalisis menggunakan uji t. Berdasarkan hasil analisis data pada motivasi belajar diperoleh thitung ≥ ttabel yaitu 2,56 ≥ 2,02, sehingga hasil pengujian hipotesis dinyatakan H0 ditolak dan Ha diterima, dan pada hasil belajar kognitif siswa biologi diperoleh thitung ≥ ttabel yaitu 16,58 ≥ 2,02, sehingga hasil pengujian hipotesis dinyatakan H0 ditolak dan Ha diterima. Maka dapat disimpulkan bahwa ada pengaruh model pembelajaran scramble dengan media crossword puzzle terhadap motivasi dan hasil belajar kognitif biologi siswa.

Abstract

The problem-based learning model is based on a constructivist paradigm, which is very student-centred and focuses on the student learning process (student centered learning). It is expected that student learning outcomes can be improved by using the PBL (Problem Based Learning) model. This research is a study of classroom behaviour. This research was conducted in the 2022/2023 academic year in class XI of SMA Swasta MIPA Imelda Medan. The research subjects were 38 students of class XI MIPA, 29 females and 9 males. Based on the results of two cycles of classroom behaviour research, the quality of the learning process and student learning outcomes can be improved by using the PBL model on respiratory system material. This model can also be trialled on other materials to see its significance. Key words: PBL Model, Learning Outcomes, and Respiratory System.   ABSTRAK Model pembelajaran berbasis masalah berdasarkan paradigma konstruktivis, yang sangat berpusat pada siswa dan menitikberatkan pada proses belajar siswa (student centered learning).

Abstract

This study aims to determine students' responses to scientific literacy-based modules on regulatory system material and to determine the feasibility of scientific literacy-based modules on regulatory system material. The product development design uses the Borg & Gall model with eight stages including, potentials and problems, data collection, product design, product validation, product revision, product testing, product revision, and the final product. This research was carried out from September to December 2021 with a research sample of 35 students in class XI SMA Yayasan Nurul Islam Indonesia. The results of this study showed that the percentage met the very feasible category with the acquisition of an average score on each aspect, namely 83% by material experts, 92% by media experts, 92% by biology teachers and 93% by students. So it can be concluded that scientific literacy-based module teaching materials are very feasible to use for teaching and learning activities.

Abstract

Strengthening Character Education (PPK) is an educational movement in schools to strengthen students' character through harmonization of heart (ethics), feeling (aesthetic), thought (literacy), and sports (kinesthetic) with the support of public involvement and cooperation between schools, family, and society. This research aims to determine the profile of strengthening character education in class X biology learning at MAN 1 Medan. The method used in this research is a qualitative method with a descriptive research type using observation, interview and documentation guide sheets in collecting data. Meanwhile, data analysis techniques involve data reduction, data presentation and conclusions. This research was carried out at MAN 1 Medan. Research submitted to describe and analyze events, phenomena, learning activities, attitudes and perceptions. The results of this research show: (1) There are 10 profiles of strengthening character education at MAN 1 Medan, namely: Civilized (ta'addub), Exemplary (qudwah), Citizenship and nationality (muwaṭanah), Taking the middle path (tawassuṭ), Balanced (tawāzun ), Straight and firm (i'tidāl), Equality (musāwah), Deliberation (syūra), Tolerance (tasāmuh), Dynamic and innovative (tathawwur wa ibtikâr). (2) The application of character education in biology learning in class social care, and environmental care. (3) Difficulty implementing character education in biology learning.

Abstract

Keterampilan berpikir kritis merupakan kompetensi penting dalam pembelajaran abad ke-21, namun masih tergolong rendah, khususnya pada pembelajaran IPA. Hal ini disebabkan oleh keterbatasan bahan ajar yang belum mampu mendorong keterlibatan aktif siswa dalam menemukan konsep pembelajaran. Oleh karena itu, diperlukan bahan ajar inovatif dan berpusat pada peserta didik, salah satunya melalui LKPD berbasis Discovery Learning. Penelitian ini bertujuan untuk mengembangkan LKPD berbasis Discovery Learning pada materi sistem ekskresi serta mengetahui tingkat kevalidan, kepraktisan, dan keefektifannya dalam meningkatkan keterampilan berpikir kritis siswa kelas VIII SMP Swasta Budisatrya. Penelitian ini menggunakan metode Research and Development dengan model ADDIE yang meliputi tahap analisis, perancangan, pengembangan, penerapan, dan evaluasi. Instrumen penelitian meliputi lembar validasi ahli materi dan media, angket respon guru dan siswa, serta tes keterampilan berpikir kritis berupa pretest dan posttest. Data dianalisis secara kuantitatif dan kualitatif. Hasil penelitian menunjukkan bahwa LKPD memiliki tingkat kevalidan sangat tinggi dengan persentase validasi ahli materi sebesar 97,7% dan ahli media sebesar 90,9%. Keefektifan LKPD ditunjukkan oleh nilai N-Gain sebesar 0,78 (78%) dengan kriteria sangat efektif. Selain itu, LKPD juga memiliki tingkat kepraktisan dengan kriteria sangat praktis berdasarkan respon guru dan siswa. Dengan demikian, LKPD berbasis Discovery Learning layak digunakan dan efektif dalam meningkatkan keterampilan berpikir kritis siswa SMP.
