Abstrak Penelitian ini dilatarbelakangi karena ditemukan kesulitan siswa ketika melakukan percobaan bandul sederhana untuk menentukan nilai percepatan gravitasi. Kesulitan – kesulitan tersebut diantaranya. Pertama, gerakan bandul yang terjadi tidak harmonis, ini bisa dikarekan ikatan bandul yang tidak baik, tali yang kurang panjang, pelepasan bandul yang tidak presisi. Kedua, hasil perhitungan nilai gravitasi jauh dari tetapan yang ada, ini dikarekan gerakan bandul yang tidak harmonis. Ketiga, Tidak tepatnya (tidak berbarengan) waktu hitung dengan waktu distop watch (selisih beberapa saat). Diduga kuat, lembar kerja yang ada kurang memfasilitasi siswa untuk melakukan percobaan dengan benar. Penelitian ini bertujuan untuk memperbaiki lembar kerja percobaan dan meredesain alat percobaan, sehingga siswa akan lebih mudah memahami cara melakukan percobaan dengan benar. Penelitian ini merupakan penelitian deskriptif analitik. Kemampuan siswa bereksperimen diperoleh dengan cara membandingkan jawaban lembar kerja siswa sebelum direkonstruksi dan jawaban siswa setelah direkonstruksi. Hasil penelitian menunjukkan bahwa lembar kerja yang telah direkonstruksi dapat meningkatkan kemampuan siswa dalam bereksperimen Kata-kata kunci: Redesain Alat Peraga dan Lembar Kerja Percobaan, kemampuan bereksperimen Abstract This study was motivated because it found students' difficulties when performing a simple pendulum experiment to determine the gravity acceleration. The difficulties are. First, the pendulum motion is not harmonious, it’s because the bond of the pendulum is not good, the rope is less long, release of the pendulum that is not precision. Second, the result of calculating of gravity acceleration is far away from the existing constellation, it’s because the movement of the pendulum that is not harmonious. Third, Not exactly (not simultaneously) the time to count with the time on the stopwatch (the difference a few moments). Existing worksheets do not facilitate students to experiment properly. This study aims to improve the experimental worksheet and redesign the experimental tool, so students will more easily understand how to experiment properly. This research is an analytical descriptive research. Students' experimental abilities were obtained by comparing the answers of student worksheets before reconstruction and student answers after reconstruction. The results show that reconstructed worksheets can improve students' ability to experiment. Keywords: Redisign experiment tools and worksheet, the experimental ability

Abstract

Each student has different characteristics in processing the information (cognitive style), including how to respond, and execute information in learning process to become a useful skills for themselves. This study aims to analyze the differences in cognitive styles of students, namely field dependent and field independent cognitive style towards mastery of concepts. The study was conducted in one of the SMP Negeri Bandung with a sample of 74 students selected by nonrandom sampling method, consisting of 36 students with field dependent cognitive style, and 38 students with field independent cognitive style. All samples do the same learning process (discussions and experiments in groups). Mastery of the concepts of physics obtained by instrument test that has been validated and tested, while the students' cognitive style classification is determined using standard instruments Group Embedded Figure Test (GEFT). The result showed that students with field dependent cognitive style increased mastery of concepts with n-gain of 0.27, while students with field independent cognitive style increased mastery of concepts with n-gain 0.23. Based on the research results, mastery concepts for field dependent students slightly larger than field independent students, it is predicted because of the learning process tend to be clustered so that more support dependent cognitive style. Keywords: field dependent, field independent, mastery concept.

Abstract

The term “metacognition” is defined as the ability of individuals to reflect, understand, and control their own thinking, learning and acting. Metacognition clasified to metacognitive knowledge and metacognitive regulation. Metacognitive knowledge consist of declaration knowledge, procedural knowledge, and conditional knowledge that refers to acquire knowledge about cognitive processes, knowledge that can be used to control their cognitive processes. The purpose of this article is to identified the metacognition knowledge of Physics Pre-Service Teacher. Six student in Solid State Physics lecture fulfill questionnaire and followed by interview. The analysis of questionnaire and interview data showed that the metacognition knowledge is still low, they could not describe about their purpose, only few of them could describe how they think, confuse what they shoud do to do the task. They only think that strategy is needed when they find difficulty and not sure with their ability to do the task. Key words: metacognitive knowledge, declarative, procedural, conditional.
