PENGEMBANGAN VIDEO PEMBELAJARAN IPA PADA MATERI PENCEMARAN DAN KERUSAKAN LINGKUNGAN

Abstrak Penelitian ini bertujuan untuk mengembangkan media belajar video pada materi pencemaran dan kerusakan lingkungan untuk siswa kelas VII SMP Inshafuddin Banda Aceh. Metode Penelitian yang digunakan adalah penelitian dan pengembangan ( research and development ) dengan model ADDIE yang terdiri dari 5 langkah, yaitu: analysis , design , development , implementation , dan evaluation . Instrumen yang digunakan adalah lembar angket validasi kelayakan media. Hasil rata-rata angket validasi yang diperoleh dari 4 validator sebesar 92,67% (sangat layak). Hasil yang diperoleh dapat disimpulkan bahwa media belajar video pada materi pencemaran dan kerusakan lingkungan yang telah dikembangkan layak diuji coba lebih lanjut untuk melihat efektivitas dalam pembelajaran.

Dampak Problem Based Learning terhadap Pemahaman Konsep Ditinjau dari Gaya Berpikir Siswa pada Mata Pelajaran Fisika

Abstract This study aims to determine studentss increased understanding of the concept in terms of thinking style after the implementation of the model-based PBL experiments on matter and energy. This study uses quasi-experimental methods, the shape of nonequivalent control group design involving two study groups namely experimental and control classes were held in MAN Rukoh Banda Aceh class XI the first semester of academic year 2015/2016 consisting of 24 students experiment class and 25 students control class. Data collection instruments; 1) Tests to see increased understanding of the concept; 2) Test thinking style questionnaire to determine the type of thinking style the students to absorb information. The results showed that: 1) There is an increased understanding the concept of students with the application of model PBL learning based experiment than higher conventional learning seen from N-Gain both classes, reaching 71% higher category for experimental class and 32% for control class. 2) On this kind of thinking style random abstract experimental class is better than the control class. On this kind of thinking style concrete sequential increase understanding concept of experimental class is better than the control class. On this kind of thinking style abstract sequential increase understanding of the concept experimental class is better than the control class. On this kind of thinking style concrete random improved understanding concept of control class reached (4.00) while the experimental group (0.00) for the experimental class did not have a concrete random thinking styles. Keywords: Model PBL Based Experiment, Concept Undertanding, Thinking Style. Abstrak Terdapat empat jenis gaya berpikir siswa yang digunakan dalam penelitian, yaitu Sekuensial Konkret (SK), Sekuensial Abstrak (SA), Acak Konkret (AK), dan Acak Abstrak (AA). Berdasarkan empat jenis gaya berpikir tersebut, jenis gaya berpikir yang paling tinggi terjadi peningkatan pemahaman konsep fisika dan indikator pemahaman manakah paling tinggi peningkatannya. Inilah tujuan yang ingin diketahui dari hasil penelitian yang dilakukan pada 24 siswa MAN Rukoh Banda Aceh kelas XI sebanyak 24 siswa untuk kelas eksperimen dan 25 siswa kelas kontrol setelah dilakukan perlakuan dengan model PBL berbasis eksperimen. Penelitian ini menggunakan metode quasi experimental, dengan desain nonequivalent control group design dan pengumpulan data menggunakan; tes untuk melihat peningkatan pemahaman konsep; dan angket untuk melihat jenis gaya berpikir yang dimiliki siswa. Hasil penelitian menunjukkan bahwa indikator pemahaman konsep “Translasi” terjadi peningkatan tertinggi pada siswa yang memiliki jenis gaya berpikir “Sekuensial Konkret (SK)” pada kelompok eksperimen, sebaliknya untuk siswa yang memiliki jenis gaya berpikir “Sekuensial Abstrak (SA)” indikator pemahaman konsep tertinggi adalah “Translasi”, ini terjadi pada kelas kontrol. Kata Kunci: Model Pembelajaran PBL Berbasis Eksperimen, Pemahaman Konsep, Gaya Berpikir.

Development and Validation of an Instrument to Access the Lecturers' Performance in the Education and Teaching Duties

The aim of this study is to identify teachers’ teaching approach, students’ learning style, and types of evaluation of Form 4 sport science subject in secondary schools. The study also meant to identify the relationship between students’ learning style with their achievement in sport science subject. Samples consist of 208 teachers who thought in sport science subject and 2729 of students who participate in the sport science subject at selected secondary schools. Instruments used in the study consist of questionnaires for teachers and students with reliability of α = .962 and α = .799 respectively. The results showed that teachers’ teaching approach based on teaching management strategy was at medium level while its teaching techniques and teachers’ content knowledge on sport science were at high level. This study also found that students acquired a high interest towards sport science subject but at of a medium level on perceptual learning style which involve visual, auditory, and kinaesthetic. The evaluation styles chosen for measuring students’ learning achievement was written test, practical test, oral test, semester examination, project, and performance evaluation. Students’ learning achievement of Form 4 sport science subject was 9.2% scored grade A, 21% grade B, 38% grade C, and 18.5% grade D. Learning factor has a low significant relationship (r = .17**, p < .00) with students’ achievement in form 4 sport science subject. In conclusion, teachers’ teaching approach should anticipate with students’ learning styles and include varieties of evaluation process to evaluate students’ learning achievement in sport science subject
