APPLICATION OF ENVIRONMENTALLY BASED EXPERIMENTAL METHODS TO IMPROVE LEARNING OUTCOMES IN ACID-BASE SOLUTION

Abstract

Based on the data obtained, the chemistry learning process still uses lecture and question-and-answer methods. Because of that the students are less active and the learning atmosphere is less enjoyable. It showed that there are still many students who are not happy when starting to learn. Students play around in learning activities; they experience difficulties and obstacles in learning, and do not understand the material presented by the teacher. The aim of this research was to determine whether environmental-based experimental methods can improve student learning outcomes in acid-based solution material in class VII of SMPN.2 Alafan, Simeulue Regency. This research method is descriptive-qualitative, which uses direct observation data on the classroom learning process. The research subjects were 19 students, consisting of 9 males and 10 females. The test was given in the form of multiple-choice questions with 20 questions. The research results showed that the completeness of student learning outcomes was 94.74%. This shows the results of learning using environmental-based experimental methods, especially on acid-based solution material.
