Efektivitas Strategi PBL Berbasis Potensi Akademik Terhadap Keterampilan Pemecahan Masalah dan Berpikir Kritis Siswa SMA Pada Topik Lingkungan

Abstract

The purpose of this research is to explain the effect of Problem Based Learning (PBL) and academic potential and their interactions toward problem solving and critical thinking skills of high school students. This research is a quasi-experiment that implements two different strategies with pretest-posttest non equivalent control group design by treatment factorial 2x2 which was conducted in the 2018/2019 academic year. Population of this research was class X students of SMA Negeri 8 Mataram, while the research sample was class X students of 2 classes with a purposive sampling technique. Research instruments is test of problem solving skills and test of critical thinking skills. Data analysis was performed with descriptive analysis and to test the hypothesis an anacova test was followed by further test used of Least Significant Difference (LSD). The calculation is aided by the SPSS 14 for Windows program. The results of this research showed that Problem Based Learning affects the problem solving and critical thinking skills. While academic ability (potential) and interaction of learning strategies with academic potential do not affect the problem solving and critical thinking skills of high school students on enviromental topic.

Problem-Based Learning: Learning Approach Solutions in Crisis Period

“…Based on the learning approaches above it was not surprising that the higher-level thinking skills of students who participated in the PBL approach were better than the higher-order thinking skills of students who participated in the conventional approach. The results of this study are the same as other studies that indicate the PBL approach could improve the comprehension conceptual and problem solving, learning outcomes, learning motivation, as well as the ability to think critically (Karmana et al, 2020). Moreover other research state that online PBL can develop skills related to employability, searching/evaluating information, developing ideas, criticizing information (Duncan et al, 2013).…”

“…Through the PBL approach, students actively develop their thinking skills from C1 to C6. Through the analysis of real problems given, students were required to find out the logical relationships between the problems given and the concepts of the mathematical material given, to identify the elements that were known, were asked about a plan of their solution (Amiluddin & Sugiman, 2016;Hastuti et al, 2017;Karmana et al, 2020).…”

Penerapan Model Problem Based Learning untuk Meningkatkan Hasil Belajar Pendidikan Agama Islam Siswa Sekolah Dasar

Problem Based Learning merupakan suatu model pembelajaran yang menggunakan masalah dunia nyata sebagai suatu dasar bagi peserta didik untuk belajar berpikir kritis dan keterampilan pemecahan masalah serta memperoleh pengetahuan dan konsep esensial dari materi pelajaran (Karmana et al, 2020).…”
