Abstract

This study aimed to determine: (1) which one is more effective between Computational Thinking BasedLearning (CTBL) and Problem Based Learning (PBL) on learning achievement, (2) which one is better,students with left brain dominance or students with right brain dominance, (3) for each brain dominance,which one is better between CTBL and PBL. This study used a quasi-experimental research method witha 2x2 factorial design. The population in this study were all students of class VIII SMPN 1 Bendo in theAcademic Year 2020/2021, totaling 9 classes. The research sample included 45 students (two classes) whowere taken using cluster random sampling. The instrument used was a questionnaire on the students’ braindominance and a mathematics learning outcome test. From the results of this analysis, it can be concludedthat CTBL was more effective to implement compared to PBL in odd semester class eight students at SMP1 Bendo Magetan in the Academic Year 2020/2021. There were differences in the results of mathematicslearning achievement in students who were given CTBL and PBL in terms of the brain dominance of oddsemester class eight students at SMPN 1 Bendo Magetan in the Academic Year 2020/2021.

Abstract

This study aimed to produce students’ worksheets (LKS) of which features are based on generative learning strategy and PMII learning that are valid, interesting and effective. This study was a development study which employed three earlier stages of 4-D (four-D) model proposed by Thiagarajan, Semmel, and Semmel. It included these stages: define, design, and develop. This study was conducted on eighth graders at SMPN 2 Malang. The results of the study showed that the worksheets were valid with an average score of 3.10. Based on the results of the tryout, it was proven that: 1) the average score of students’ questionnaire was high: 3.29. It means that the LKS was appealing to students and 2) the results of the interview conduted to the teacher revealed that the worksheets were quite interesting and applicable. The LKS was also effective. It was seen from the level of students’ mastery (87.5%): the students understand the materials very well with the LKS.Tujuan penelitian ini adalah menghasilkan LKS bercirikan strategi generatif dengan pembelajaran PMII yang valid, menarik dan efektif. Jenis penelitian ini adalah penelitian pengembangan yang mengadopsi 3 tahap pertama model pengembangan 4-D (four-D) yang dikemukakan oleh Thiagarajan, Semmel dan Semmel yang meliputi tahap pendefinisian (define), perancangan(design), dan pengembangan (develop). Penelitian ini dilaksanakan di SMPN 2 Malang pada siswa Kelas VIII. Hasil penelitian menunjukkan bahwa LKS yang dikembangkan valid dengan skor rata-rata 3,10. Berdasarkan hasil uji coba diperoleh: 1) skor rata-rata angket siswa tinggi  yaitu 3,29, sehingga LKS menarik bagi siswa dan 2) hasil wawancara guru disimpulkan bahwa LKS menarik bagi siswa dan dapat digunakan. LKS juga memenuhi aspek keefektifan. Hal ini dapat dilihat dari tingkat ketuntasan siswa yaitu 87,5% artinya pemahaman siswa setelah belajar menggunakan LKS sangat baik.
