Using Project-Based Learning in Improving Students' Critical Thinking Skills to Separate of Mixtures

Abstract

Nowadays the development of thinking skills has become the main focus in educational research. Standard of graduate competency mandate that graduates of schools to universities in Indonesia must have thinking skills. Related to this, the goal of this quasi-experimental study was to describe the effectivity of Project-Based Learning (PjBL) student worksheets to improve students' critical thinking skills (CTS) in the topic of mixtures separation. This study was carried out in the SMPN 1 Pugung by using the Non-Equivalent (Pretest-Posttest) Control Group Design. The effectivity of PjBL student worksheets measured based on the n-gain and the effect size values. Statistically, the n-gain value of the experimental class was higher than the control class. The effect size value was in medium categorized. These results indicated that the PjBL student worksheets were effective to improve students' CTS in the topic of mixtures separation. Keywords: student worksheets, project-based learning, critical thinking skills, mixtures separation

Literature Study: Utilization of the PjBL Model in Science Education to Improve Creativity and Critical Thinking Skills

“…While the treatment of the PjBL learning method also further develops the assertive reasoning skills of students who are accounted for from the results of exploration, this is what we know as critical thinking (Andini & Rusmini, 2022;Trimawati et al, 2020;Insani et al, 2018;Sumardiana et al, 2019;Istiqomah et al, 2022;Fathimatuz, 2020;Yustina, 2020).…”

Effect of Scaffolding Provision an Acid and Base Learning Project on Students' Science Process Skills

“…Ennis said that critical thinking skills (CTS) are reasonable reflective thinking that focuses on deciding what to believe or do. CTS skills are considered as selfregulation in deciding that has a purpose that results in interpretation, analysis, evaluation, and inference as well as real, conceptual, methodical, criteria, or contextual considerations of the decisions taken (Insani et al, 2018).…”

“…Apart from that, PjBL also encourages students to think outside the box and not be afraid to try new things(Rakhmatdi et al, 2023;.Ennis said that critical thinking skills (CTS) are reasonable reflective thinking that focuses on deciding what to believe or do. CTS skills are considered as selfregulation in deciding that has a purpose that results in interpretation, analysis, evaluation, and inference as well as real, conceptual, methodical, criteria, or contextual considerations of the decisions taken(Insani et al, 2018).Meanwhile, creative thinking is a skill to develop, discover, or make new constructive combinations based on existing data, information, or elements, with a different point of view that arises as a manifestation of a perceived problem, resulting in something useful. Previous research shows that creative thinking is influenced by a variety of circumstances, including the extent to which individuals are able to collaborate and are motivated to solve problems.…”

“…Pendidikan dikatakan dapat mengembangkan potensi yang dimiliki oleh mahasiswa jika didukung oleh proses pembelajaran yang baik. Masalah yang dihadapi dunia pendidikan terutama di tingkat perguruan tinggi yaitu masih rendahnya kemampuan berpikir kritis mahasiswa (Insani, 2018;Wiyoko, 2019). Dilihat dari proses pembelajaran, mahasiswa kurang didorong untuk mengembangkan potensi yang dimilikinya, salah satunya yaitu kemampuan berpikir kritis (Setiawati & Corebima, 2017).…”
