Development of Student Worksheets Using the Contextual Teaching and Learning (CTL) Approach on Algebraic Operations Material
Keywords:
Contextual Teaching and Learning (CTL), Student Worksheet (LKS), Algebraic OperationsAbstract
The background of the research is the lack of student engagement in learning and the lack of interesting teaching materials. The aim of this research is to develop a student worksheet (LKS) using the Contextual Teaching and Learning (CTL) approach on algebraic operations material for Grade VIII students at SMPN 3 Talamau, which is valid, practical, and effective. This type of research is development research. The product trial was conducted in class VIII.3 of SMPN 3 Talamau, consisting of 30 students. The product developed is a Student Worksheet. The instruments used in this research include validation sheets, practicality sheets, and learning outcomes. The LKS consists of 4 learning activities. The general structure of the LKS includes a cover, competencies to be achieved, material, instructions for using the LKS, exercises, reflection, and authentic assessment. The LKS was developed using the ADDIE development model, which includes: a) Analysis: syllabus analysis, curriculum analysis, needs analysis, indicating the limited availability of teaching materials, and that students have not been actively involved in the learning process; b) Design: collecting references, designing material content according to CTL aspects; c) Development: creating teaching materials, validation by validators to determine the validity of the teaching materials, and revising the product; d) Implementation: testing to obtain practicality and effectiveness of using the LKS; e) Evaluation: analyzing the practicality and effectiveness of the LKS. The quality of the developed LKS is: a) validity with a very valid category based on the validator's assessment with an average score of 91.8%; b) practicality with a very practical category based on teacher and student assessments with average scores of 91.57% and 81.25%, respectively; c) effectiveness with a very effective category based on student learning outcomes tests with a percentage of 80%.
