Abstract

Pembelajaran saat ini mengutamakan terwujudnya karakter yang baik pada peserta didik. Penggunaan etnosains sebagai pendekatan diharapkan mampu mewujudkan hal tersebut. Namun, hingga saat ini pendekatan etnosains belum banyak dilakukan dalam pembelajaran kimia. Sebagai upaya mengembangkan model pembelajaran kimia berbasis etnosains perlu dilakukan penelitian terkait tanggapan guru kimia selaku praktisi terhadap pendekatan etnosains dalam pembentukan karakter siswa melalui pembelajaran kimia. Penelitian ini merupakan penelitian kualitatif dengan melibatkan 113 guru kimia sebagai responden. Alat pengumpul data yang digunakan adalah kuesioner yang berisi pernyataa terkait pembelajaran kimia dan pendekatan etnosains. Hasil penelitian menemukan bahwa sebagian besar guru belum menggunakan pendekatan etnosains dalam pelaksanaan pembelajaran kimia baik pembelajaran di kelas maupun di laboratorium. Pembelajaran kimia dengan pendekatan etnosains perlu dikembangkan untuk dapat membangun karakter siswa. Perlu dikembangkan model pembelajaran dan modul pembelajaran dengan memasukkan unsur budaya dan sesuai dengan kurikulum 2013 agar siswa lebih memahami konsep kimia dan mengenal budaya sekitar sehingga mengubah persepsi siswa bahwa kimia dekat dengan kehidupan sehari-hari.

Abstract

This study aims to compare the effectiveness of guided inquiry, open inquiry, and tiered inquiry in biochemistry learning. The effectiveness is seen from the product-process perspective, i.e., by looking at critical thinking scores and responses of lecturers' teaching activities. This study involved three groups treated with guided inquiry (level 1), open inquiry (level 2), and tiered inquiry (level 1 to level 2). The number of respondents was 72 students spread over the three groups. Before being given treatment, the three groups were tested for prior knowledge, and it was obtained that the three groups had the same initial ability. The research instrument used was critical thinking questions and a questionnaire of responses to the learning process. The results showed that the group with tiered inquiry treatment had the highest critical thinking score, while open inquiry had the lowest score. It is in line with the respondents' responses related to the learning process. Students feel easier and more comfortable in the tiered inquiry process than the guided and open inquiries. The results of the Mann-Whitney U test analysis on the three treatments showed that the three groups had significantly different critical thinking scores. It can be concluded that tiered inquiry is more effective in Biochemistry learning than guided and open inquiries.

Abstract

The COVID-19 pandemic has changed the face-to-face learning process to online learning. It requires learning innovations that can make students more independent in exploring concepts. Case-based learning can be an alternative in the online learning process. This study aims to develop a case-based learning model in online biochemistry learning. This study uses six stages to modify the stages of development research. The results showed that the learning model developed consisted of five phases which became the syntax of the learning model developed, namely (1) Planning; (2) Orientation; (3) Organization; (4) Implementation; and (5) an evaluation developed following the results of the needs analysis. The developed syntax is described in model implementation guidelines and is equipped with learning tools. The validator's assessment shows that the model and device instructions have an index value of the expert agreement with a valid category. The test results on students showed that all the stages described in the guidelines could be implemented properly. Students gave a positive response to the implementation of case-based learning. Thus, case-based learning can be recommended for further learning.
