Abstract

Penelitian ini bertujuan untuk menganalisis miskonsepsi konsep gaya pada calon guru fisika. Sebanyak 24 calon guru fisika diberikan tes standar mengenai konsep gaya yaitu force concept inventory (FCI). Metode penelitian yang digunakan dalam penelitian ini merupakan metode penelitian deskriptif. Hasil data yang diperoleh kemudian di analisis menggunakan Certainty of Respond Index (CRI), dimana analisis terhadap data dibedakan kedalam tiga kategori yaitu tahu konsep, tidak tahu konsep, dan miskonsepsi. Hasil analisis data diperoleh bahwa rataan miskonsepsi 53%, tidak tahu konsep 24%, dan tahu konsep 23%. Analisis lebih lanjut terhadap beberapa butir soal diperoleh beberapa miskonspesi dengan tingkat miskonsepsi lebih dari 40%, yaitu: 1). kecepatan yang besar menimbulkan percepatan yang besar pula, 2). penjumlahan kecepatan dijumlahkan sama seperti penjumlahan biasa tanpa melibatkan arah, 3). kelajuan benda meningkat secara kontinu setelah menerima gaya sesaat, 4). kelajuan benda meningkat kemudian setelahnya menurun pada sistem yang dikenai gaya tetap, 5). gaya gravitasi berkurang dan meningkat pada sistem gerak yang dilempar dan jatuh kembali, 6).  Resultan dua gaya yang membentuk sudut satu sama lain akan mempunyai resultan dengan arah berada tepat ditengah kedua gaya asal.

Abstract

Ikan sebagai hewan air memiliki mekanisme fisiologis yang tidak dimiliki hewan darat. Ikan dapat merespon arus listrik karena memiliki organ elektroreseptor. Secara umum, elektroreseptor merupakan pengembangan dan modifikasi gurat sisi atau lateral line. Untuk mengetahui bahwa ikan dapat merespon arus listrik dilakukan penelitian dengan melakukan perbandingan ketahanan ikan lemon (Lubia caeruleus) dengan ikan lele pada tegangan 18 volt. Digunakan plat PCB sebagai pengantar arus listrik antara katoda dengan anoda pada dengan tegangan 18 volt, dengan medan listrik yang dihasilkan sebesar 171 v/m. Dari hasil pengamatan respon ikan terhadap medan listrik mempengaruhi perilaku ikan karena terinduksi oleh arus tersebut dan ikan menuju wilayah yang efektif dari elektroda. Ikan lele (Clarias batrachus) lebih kuat ketahanan tubuhnya dalam merespon arus listrik dibandingkan ikan lemon (Lubia caeruleus).

Abstract

This research originated from the interviewing between the researcher as a physics teacher to some students about Physics assignments. Based on the interview, student felt so bored in doing their assignment and have no motivation in finishing it. Because there is no motivation in doing the assignment therefore the understanding of the students could not be increasing. Based on Curtis (2009:1) that motivation of the students could be increased by implementing  Project Based learning (PBL). This research tried to see the influence of PBL toward the motivation and the understanding of the students. In this assignment students are asked to making a video about the application of Newton’s law of Motion in daily Life. From this video students analyzing why do the video can categorize as the application of Newton’s Law of Motion in daily Life. In making the video as the project, students are guided by the rubric, the timeline and also the goal of the project. Students have to finish their project in fifteen days, and teacher scored their project based on two criteria: the contents and presentation. Ten best video would be shown in front of the whole students in an event in the school. To see the understanding and the motivation of the students after finishing the project, the teacher gave the test and also the questionnaire about the project and their comprehension of Newton’s Law of Motion. According to the questionnaire we can see that more than 60% of the students agree that the project can increase their motivation and also their understanding. The increasing of students comprehension can be seen from the test that given to students. From this research we can inferred that project base learning can stimulus student’s motivation and also the understanding.

Abstract

ABSTRAK Penelitian ini bertujuan untuk mendapatkan gambaran tentang peningkatan pemahaman konsep melalui penerapan dua model pembelajaran (Discovery Learning_DL dan Guided Discovery Learning_GDL) pada kelompok yang berbeda dan signifikansi perbedaan peningkatan pemahaman konsep yang lebih signifikan diantara penerapan kedua model tersebut pada kelas yang telah di-treatment. Penelitian ini menggunakan pendekatan kuantitatif dimana desain yang dipakai ialah pretest-posttest control group design dengan menginovasi kelas kontrol menggunakan model pembelajaran GDL. Sampel yang dipakai menggunakan kluster acak dengan mempertimbangkan homogenitas antara kelas. Untuk mengukur peningkatan pemahaman konsep digunakan tes pemahaman konsep berbentuk pilihan ganda. Hasil analisis data menunjukkan bahwa model pembelajaran DL mampu meningkatkan pemahaman konsep dengan kategori sedang (rerata n-gain= 0,49) dan  GDL tergolong kategori rendah (rerata n-gain = 0,23). Perhitungan uji statistik uji-t menunjukkan bahwa tidak terdapat perbedaan yang signifikan dalam peningkatan pemahaman konsep antara kelas yang mendapatkan pembelajaran model DL dengan kelas yang mendapatakan pembelajaran model GDL (sig.2-tailed: 0,183, = 5%). Diharapkan pada penelitian selanjutnya untuk memaksimalkan eksperimen pada kedua model agar mendapatkan hasil yang lebih baik dan diupayakan diuji pada konsep lainnya. ABSTRACTThis research aim to get description of the increasing conceptual understanding through implementation of two type learning model (Discovery Learning and Guided Discovery Learning) to two difference class and to know which the differences of mean more significant to increase conceptual understanding between DL and DL learning model.

Abstract

The purpose of this study was to describe the science learning process and the teaching materials used by teachers in science learning. The type of research to be conducted is descriptive quantitative research. Respondents in this study were 26 students of class VIIIA MtsN 6 Sijunjung. The research instrument was in the form of a questionnaire filled out by students and an interview sheet with the educator. The result of the research is that the science learning process is more predominantly carried out through the lecture method compared to the experimental / practicum / inquiry labs method by 83% and the teaching materials most often used by teachers in science learning are textbooks by 85%. Science learning has not facilitated students to have scientific literacy because science learning is more often carried out by the lecture method. Thus, teachers need to develop appropriate teaching materials in order to increase students' motivation and scientific literacy.
