The Effect of Collaborative Learning Model Combined with Problem Solving on Critical Thinking Ability and Mastery of Biology Concept of High School Students in Coffee Plantation Area

Abstract

The characteristics of students who live in a school environment near coffee plantations have low learning independence, so it is necessary to have independent learning guided by a teacher in order to foster a scientific attitude in students. The Collaborative Learning model combined with Problem Solving is a combination of two learning approaches, namely cooperative learning and problem-based learning. Both of these learning models make it possible to create a collaborative learning environment. Learning environments that support students to collaborate naturally and effectively are very important because they can develop knowledge through their own experiences. Critical thinking is included in higher order thinking skills that have the potential to increase students' critical analytical power. When students have critical thinking skills, students will carry out decision-making, strategic planning, scientific processes, and problem solving activities. The existence of problem-solving skills will also affect students' mastery of concepts. Concept mastery can be interpreted as the ability to master ideas or ideas about certain objects, events or situations that can be generated because of a number of relevant experiences. Keywords: Collaborative Learning, Problem Solving, Critical Thinking Ability, Mastery of Concept.
