Abstract


ABSTRAK

Telah dilakukan penelitian eksperimental tentang model pembelajaran Two Stay Two Stray di salah satu SMA di Kota Bandung. Penelitian ini bertujuan untuk menganalisis tingkat pemahaman konsep siswa pada materi momentum dan impuls dengan menggunakan model pembelajaran two stay two stray (TSTS). Pemahaman konsep siswa diukur dengan tes diagnosis berupa tes pilihan ganda dengan menggunakan skala Certainty of Response Index (CRI). Metode penelitian adalah Quasi Experimental dengan desain One Group Pretest Posttest yang melibatkan 37 orang siswa. Hasil penelitian menunjukan bahwa pemahaman konsep siswa SMA pada materi momentum dan impuls setelah pembelajaran meningkat, yaitu 16,8% pada pretest menjadi 70,6% pada posttest. Keefektivitasan pembelajaran dengan menggunakan model TSTS ini dapat dilihat dari nilai N-gain sebesar 0,64.

ABSTRACT

Experimental research about Two Stay Two Stray (TSTS) learning model has been conducted in one of senior high school in Bandung. This research aimed to analyze students’ understanding of momentum and impulse concepts by using TSTS learning model. Students’ conception were identified by multiple choice-diagnostics test using Certainty of Response Index (CRI) scale. Research method was pre-experimental design with one group pretest posttest design involving 37 students as research subjects. Results showed that profile of students’ understanding of momentum and impulse concepts were increased from 16,8% in pretest to 70,6% in posttest. Effectiveness of TSTS learning model was reflected by N-gain of 0.64.


Keywords
