Abstract

Worksheets can be used as a solution to the success of the practicum process. This study aimed to analyze students' creative thinking skills through worksheets of microbial growth rates on nata de whey kefir. The method used in this research was a Pre-Experimental Design with a one-group pretest-posttest design. The population of this research was the sixth-semester Biology Education Study Program students. The research sample consisted of a class of 21 students selected using a purposive sampling technique. The research instrument consisted of description questions containing indicators of creative thinking. The results of the research data analysis obtained an average N-gain for each indicator of creative thinking skills of 0.461, which was included in the "medium" criteria. Test the data hypothesis using the T-paired test obtained a significance value of 0.000 <0.05. Therefore, H0 was rejected, and H1 was accepted. Based on the research results obtained, data showed that there was an increase in students' creative thinking skills through worksheets on the rate of microbial growth in nata de whey kefir.ABSTRAK: Lembar kerja dapat digunakan sebagai solusi dalam keberhasilan proses praktikum. Penelitian ini bertujuan untuk menganalisis keterampilan berpikir kreatif mahasiswa melalui lembar laju pertumbuhan mikroba pada nata de whey kefir. Metode yang digunakan dalam penelitian ini adalah Pre-Experimental Design dengan desain penelitian one-group pretest-posttest design. Populasi penelitian ini adalah mahasiswa semester VI Program Studi Pendidikan Biologi. Sampel penelitian menggunakan satu kelas yang berjumlah 21 mahasiswa dengan menggunakan teknik purposive sampling. Instrumen penelitian terdiri dari soal uraian yang memuat indikator berpikir kreatif. Hasil analisis data penelitian diperoleh rata-rata N-gain dari setiap indikator keterampilan berpikir kreatif sebesar 0,461 termasuk pada kriteria “sedang”. Data uji hipotesis dengan menggunakan Uji T-paired diperoleh nilai signifikansi 0,000 < 0,05 maka H0 ditolak dan H1 diterima.  Berdasarkan hasil penelitian diperoleh data bahwa terdapat peningkatan keterampilan berpokir kreatif mahasiswa melalui lembar kerja laju pertumbuhan mikroba pada nata de whey kefir.

Abstract

This study aims to analyze the implementation of the Student Teams Achievement Divisions (STAD) learning model in improving students’ argumentation skills, learning activities, and responses on biodiversity topics integrated with Islamic values. This research employed a quasi-experimental method with a non-equivalent control group design, involving an experimental class applying STAD and a control class using conventional instruction. The instruments used included an argumentation skills test, learning implementation observation sheets, and student response questionnaires. The results indicate that learning implementation in the experimental class reached an average of 88% for teachers and 89% for students, while the control class achieved 82% and 80%, respectively, both categorized as good. Improvement in argumentation skills in the experimental class is shown by an increase in the average score from 62.56 to 82.08 with an N-Gain of 0.51 (moderate), whereas the control class increased from 58.77 to 71.48 with an N-Gain of 0.26 (low). The posttest hypothesis test revealed a significant difference with a Sig. value of 0.002, supported by an effect size of 0.87, classified as large. Student responses toward STAD reached an average of 68.31% (fair), higher than the control class at 65.78%Thus, the implementation of STAD integrated with Islamic values is proven effective in enhancing students’ argumentation skills.
