Abstract

This research and development aims to produce a product in the form of problem solving-based LKS learning tools in mathematics subjects with algebraic function limits for Class XI students at SMAN Jatirogo by looking at the validity, practicality and effectiveness of the LKS. The research method used is the research and development method, the development research model used is the ADDIE development model which consists of 5 stages, namely analysis (analysis) design (design), development (development), implementation (implementation), evaluation (evaluation). From the analysis results obtained, the development of learning tools using the ADDIE model to produce good problem solving-based learning tools, because the resulting learning tools are learning tools that meet the criteria of all aspects that have been set. The results show that the quality of the LKS produced is as follows: 1) aspects of validity with validation by ahh the material that meets the criteria is very valid with a percentage of validity of $6.92%. 2) the practicality aspect meets the very practical criteria obtained from student response questionnaires with a practicality percentage of 81.20%. 3) the aspect of effectiveness meets the effective criteria obtained and the learning outcomes test uses the t-test test with the decision criteria, namely tcount <teabel of classical student completeness with a completeness result of 80% with a very high category. Keywords: Development, Problem Solving, Limits of Algebraic Functions
