Data hasil survey pra-penelitian menunjukkan keterampilan proses sains siswa masih dalam kategori cukup dan rendah. Rendahnya keterampilan proses sains siswa akan berpengaruh pada penilaian ketiga ranah standar kompetensi lulusan yang meliputi kemampuan kognitif, afektif, dan psikomotor. Metode pembelajaran student created case studies digunakan sebagai alternatif untuk meningkatkan keterampilan proses sains siswa. Penelitian ini bertujuan untuk menganalisis keefektifan metode pembelajaran student created case studies untuk meningkatkan keterampilan proses sains siswa. Penelitian ini merupakan penelitian eksperimen dengan desain pre-test and post-test control group design, dengan populasi penelitian siswa kelas X IPA SMAN 1 Kalasan kemudian dilakukan sampling dengan metode simple random sampling. Teknik analisis data menggunakan uji independent t-test dan uji N-gain. Hasil penelitian menunjukkan penggunaan metode pembelajaran student created case studies efektif untuk meningkatkan keterampilan proses sains siswa pada materi kingdom plantae. Penggunaan metode pembelajaran student created case studies dapat membiasakan siswa untuk menerapkan konsep keterampilan proses sains.

This study aims to find out the profile of teachers' constructivist practice and it effects on self-efficacy and student cognitive learning outcomes. The subjects of the study are two Biology teachers and a group of first year high school students in Kayen district, Pati. The instrument of data collection is consists of questionnaire, observation sheet, and score document. The data of the research are analyzed with quantitative approach. The results show that both teachers get average score of 3,16 and 3,63. Those scores are classified as high criterion. Based on the N-gain test, the result of students’ cognitive learning has medium to high criteria. The students' cognitive and self-efficacy learning outcomes in all classes before and after constructivist practice on learning by teachers significantly differ (p <0.05). Although the result of student's self-efficacy in N-gain test shows low to moderate criteria, the result of the analysis shows that there is positive correlation in students’ self-efficacy caused by constructivist practice by teachers with cognitive learning outcomes. It can be concluded that a profile of teachers' constructivist practice is classified as high category which has positive effect on self-efficacy and student learning outcomes.

Subyek penelitian adalah dua orang guru mata pelajaran Biologi dan siswa kelas X IPA di salah satu SMAN di Kayen Kabupaten Pati. Instrumen pengambilan data penelitian terdiri atas angket, lembar observasi, dan dokumen nilai. Data hasil penelitian dianalisis dengan pendekatan kuantitatif. Hasil penelitian menunjukkan bahwa praktik konstruktivis guru dalam pembelajaran oleh guru A memperoleh rata-rata skor 3,16 dengan kriteria tinggi, guru B memperoleh rata-rata skor 3,63 dengan kriteria tinggi. Berdasarkan uji N-gain hasil belajar kognitif siswa kelas X IPA.1sampai X IPA.5 dengan kriteria sedang sampai dengan tinggi. Hasil belajar kognitif dan self-efficacy siswa di semua kelas sebelum dan sesudah praktik konstruktivis pada pembelajaran oleh guru menunjukkan perbedaan yang signifikan (p< 0,05).

The observation results at X IPA class in SMAN 1 kalasan are student's interest in biology getting low and their attitude toward science in Biology tend to be negative. This study aimed to know the effectivity of student created case method in improving attitude toward science. This study employed a quasi-experimental with a pretest and post-test control group design. The population of the study was X IPA SMA 1 Kalasan students. Independent t-test and N-gain test was used for the data analysis technique. The results of the Independent t-test analysis showed sig. (2-tailed) 0,000 that means H0 was rejected, the N-gain test analysis in the control class had a value of 0.04 while the experimental class had a value of 0.24. The data analysis showed that the student created case studies method is effective to improve student's attitude toward science in kingdom plantae materia.
