PROBLEM BASED LEARNING, MOTIVASI BELAJAR, KEMAMPUAN AWAL, DAN HASIL BELAJAR SISWA SMK

Abstract: Problem Based Learning, Learning Motivation, Prior Ability, and Learning Outcomes of SMK Students. The present study examines the influence of Problem Based Learning (PBL), learning motivation, and the prior ability of vocational school students. The study employed nonequivalent control group quasi exsperimental design. 75 eleventh graders in the academic year of 2012/2013 were randomly assigned into the experiment and control groups. A test was administered to assess the prior ability (entry behavior) and learning outcomes, and self-inventory was used to elicit the students’ learning motivation. The three-way analysis of variance shows that there was a significant difference between the students taught using the problem-based learning and those taught using the conventional method, between those with high learning motivation and those with low motivation, and between those with higher prior ability and those with low ability. Additionally, there was significant interaction among teaching-learning models, learning motivation, and prior ability. Abstrak: Problem Based Learning, Motivasi Belajar, Kemampuan Awal, dan Hasil Belajar Siswa SMK. Penelitian ini bertujuan menguji pengaruh Problem Based Learning (PBL), motivasi belajar, dan kemampuan awal terhadap hasil belajar siswa SMK. Digunakan kuasi eksperimen dengan rancangan non­equivalent control group design. Kelompok eksperimen dan kontrol direkrut secara assigment random sampling. Subjek berjumlah 75 siswa Kelas XI Tahun 2012/2013. Tes digunakan untuk mengukur ke­mampuan awal dan hasil belajar, dan self-inventory digunakan untuk mengukur motivasi belajar siswa. Data dianalisis dengan Analisis Varian Tiga Jalan. Hasil penelitian menunjukkan bahwa ada perbedaaan hasil belajar yang signifikan antara kelompok pembelajaran PBL dengan kelompok pembelajaran konven­sional, antara kelompok siswa yang bermotivasi belajar tinggi dan rendah, dan antara kelompok siswa yang berkemampuan awal tinggi dan rendah. Ada interaksi yang signifikan antara model pembelajaran, motivasi belajar, dan kemampuan awal terhadap hasil belajar siswa. Artinya, hasil belajar siswa tergantung dari model pembelajaran, motivasi belajar, dan kemampuan awal siswa
