APPLICATION OF PROBLEM-BASED LEARNING MODELS TO INCREASE INTEREST IN LEARNING BASIC NATURAL SCIENCES

Abstract

The problem in this study is that not all students have high activity in learning. Many students have low activity. Low activity shows that students' interest in learning basic natural sciences is still low. The author tries to apply a learner-centered learning model, namely Problem Based Learning. Problem Based Learning is a problem-based learning model with several stages of learning. The method used is done in collaboration and discussion to explore learning concepts critically and creatively using scientific calculator learning media. Scientific calculators work for presentations, affirmations, calculations, and exploration of mathematical ideas, relationships, and problems. The author's initial preparation is to develop a Learning Implementation Plan (RPP) and Student Worksheets (LKPD). The question that is used as a starting point for learning is trigonometry. The instruments used were observation sheets to observe the activities of students during learning, and a learning interest questionnaire to express students' interest in learning in activities before, during, and after learning. The data analysis technique used is the percentage technique. The results of data processing showed that the average student learning activity increased from the initial condition of 15.47%. The results of the students' learning interest questionnaire before the learning activities were 80.26%, during the learning activities 76.90% and after the learning activities 81.14%. Based on the results of the application of the Problem Based Learning model, it can be concluded that the learning interest in learning basic natural sciences increases by using scientific calculator learning media
