DEVELOPMENT OF LEARNING SET BASED ON SCIENTIFIC APPROACH IN THE TOPIC OF CIRCLE TO IMPROVE STUDENTS' MATHEMATICS LEARNING ACHIEVEMENT FOR JUNIOR HIGH SCHOOL GRADE VIII

Abstract

This study aims to produce learning set using scientific approach which comprises lesson plan
and student worksheet in the topic of circle to improve students' mathematics learning achievement for
junior high school grade VIII which are valid, practical, and effective. Learning set using scientific
approach consists of observing, asking, collecting information, associating, and communicating. Type
of this study is research and development with ADDIE model, which includes Analysis, Design,
Development, Implementation, and Evaluation. The instruments which are used in the research namely
the evaluation sheets of learning set to measure validity, questionnaire of response from teacher,
questionnaire of responses from students, and observation sheet of learning implementation to measure
the practicality, and mathematics learning achievement test to measure the effectiveness of the
learning set. This research produces learning set in the form of four lesson plan and one student
worksheet. Learning set complies the validity criteria for lesson plan with the average score of 1.00
from maximum score of 1.00 for guttman scale and the average score of 4.15 from maximum score of
5.00 for likert scale, while for student worksheet with the average of 4.21 from maximum score of
5.00. Learning set complies the practicality criteria with the average score of 4.44 for the questionnaire
of respone from teacher, 4.15 for the questionnaire of responses from students, from maximum score
of 5.00, and the average percentage of 93.33% from maximum percentage of 100% for observation
sheet of learning implementation. Based on the results analysis of the mathematics learning
achievement test, learning set complies the effectiveness criteria, is indicated by the percentage of
students completeness in minimum completeness criteria of 87.10%.
