The Development of PBL-Based Worksheets Integrated with Green Chemistry and Ethnoscience to Improve Students’ Thinking Skills

Abstract

In today's global era, thinking skills are essential to be mastered by students. This research intended to develop and implement PBL-based worksheets integrated with green chemistry and ethnoscience to improve thinking skills, which included generic science skills and critical thinking skills. These skills were observed through learning outcomes, which were divided into three domains, i.e., cognitive, psychomotor, and affective. The cognitive aspect was assessed through pre-and post-test results, the psychomotor domain was valued through an essay test and observational sheets, and the affective domain was evaluated using questionnaires and observational sheets. This research was conducted with XI graders of MAN I Semarang and SMA Pekalongan. There were three rounds implemented; first, preliminary research which has observed the problems in chemistry learning, particularly on the hydrolysis topic and continued to the development of worksheets, then validated. The next round was the implementation of the worksheets. The N-gain test was used to see the influence of the developed worksheets on the increase in critical thinking skills and generic science skills. The critical thinking scored 0.58 (moderate), while the generic science, which covered scale awareness and logical inference, scored 0.63 (moderate) and 0.73 (high), respectively. A paired t-test results revealed that there was a remarkable increase in the logical inference and awareness of scale. Moreover, the results of the study found that the applied worksheets were practical for cognitive, affective, psychomotor seen from the learning outcomes.

The Effect of Search, Solve, Create and Share Learning Models to Improve Students 'Critical Thinking Skills on Acid and Basic Titration Materials

“…Education has an important role in advancing every nation, through education it can direct students to become qualified human beings who are able to face challenges that always change with the times. Sudarmin, et al (2019) stated that in the current global era, the ability to think is very important for students to master. Therefore it is necessary to find ways to develop each potential of each student.…”

Pembelajaran Tematik Berbasis Etnosains Dalam Meningkatkan Literasi Budaya dan Kewargaan Siswa Sekolah Dasar

“…Melalui penelitian ini dikembangkan sebuah pembelajaran yang mengintegrasikan budaya lokal membatik kayu. Kegiatan membatik kayu ini telah berlangsung secara turun temurun sehingga dapat disebut sebagai sebuah budaya lokal (Tulu et al, 2019;Sudarmin et al, 2019;Hastuti et al, 2019;Paul M. Muchinsky, 2012). Budaya lokal membatik kayu ini adalah bagian utama dalam pembelajaran tematik berbasis etnosains.…”

Pengaruh Praktikum Kimia Hijau Pada Sikap Siswa Terhadap Kimia

“…Prinsip-prinsip kimia hijau telah diintegrasikan dalam praktikum kimia skala kecil (Listyarini et al, 2019;Ratnasari, et al, 2019). Di samping itu, praktikum kimia hijau mampu meningkatkan keterampilan proses sains (Putra, et al, 2018;Harta et al, 2019), keterampilan berpikir kritis (Faludi & Gilbert, 2019;Kurowska-Susdorf et al, 2019;Sudarmin et al, 2019), kesadaran akan kelestarian lingkungan (Nurbaity et al, 2016), sikap siswa terhadap lingkungan (Auliah et al, 2017), literasi sains dan komunikasi (Hardianti & Wusqo, 2020), kemampuan siswa merancang eksperimen (Pamenang et al, 2020), hasil belajar Wulan et al, 2020), serta motivasi belajar siswa (Lokteva, 2018). Motivasi belajar dapat meningkatkan hasil belajar (Keller., 2017;Taştan et al, 2018).…”
