Abstract

Problem-solving ability is one of the abilities that support the achievement of the Profil Pelajar Pancasila. In reality, problem-solving skills are still low and need to be improved. Based on the literature study, student worksheet learning tools using the inquiry model can train problem-solving skills. The research objective is expected to produce an effective student worksheet to improve problem-solving skills on the material of factors that affect the reaction rate. The student worksheet was developed following the ADDIE (Analyze, Design, Develop, Implement, Evaluate) stages, up to the develop and pilot implementation stage. The pilot implementation target was 28 students of class XI-3 SMA Negeri 7 Surabaya. Student worksheets in this study were developed referring to the indicators of problem-solving ability, namely recognising the problem, describing the problem, planning a solution, executing the plan, and evaluating the solution. The effectiveness of the student worksheets was determined based on the results of the problem-solving ability test. The effectiveness test design used was a one-group pretest-posttest Design. Pretest and posttest data were analyzed using a normality test and a paired t-test. The student worksheet developed was declared effective if there was an increase in students' problem-solving ability test scores between before and after the trial.  The problem-solving ability test results were tested with the Shapiro-Wilk test. The prerequisite test results showed normal distribution because the p-value> 0.05. Followed by hypothesis testing using a paired t-test (one-tail).  Data analysis using a paired t-test (one-tailed) resulted in a p-value of 0.000 <0.005, so there was a significant increase in the problem-solving score. Thus, student worksheets developed using the inquiry model are declared effective for improving students' problem-solving skills in the material of factors that affect the reaction rate.

Abstract

Chemistry is one of the fields of science that involves many concepts and is prone to misconceptions. This is because books, information from other people and the internet, misinterpreted experiences, and other sources provide inaccurate or incomplete information. Teachers are responsible for transferring knowledge or information and ensuring that the knowledge or information is understood correctly so that the teacher's ability to detect students' conception profiles becomes one of the competencies that teachers must have. Chemistry teachers in Mojokerto Regency and City need to map students' conceptions related to chemical concepts not only considering aspects of students' thinking skills. This is the basis for the community service team who have the initiative to provide training on Student Concept Mapping on Chemistry Material in Mojokerto Regency and City. The results obtained were that teachers' understanding of the development of diagnostic tests improved, from 57.14% to 88.09% and was proven by the preparation of diagnostic tests developed by teachers on acid-base, chemical bonds, and hydrocarbon materials. Keywords: training, mapping, chemical conception
