Abstract

This research purpose to describe the implementation of inquiry learning integrated by Nested, students' activities, critical thinking skills and student learning outcomes after the implementation of learning models on electrolyte and non-electrolyte solution materials. The research design used is "one group pre-test post-test design". The method used in this study is observation and test methods. The results of the study indicate the application of learning gained an average percentage at meeting 1 of 93.75% and at the second meeting of 97.91% with very good criteria and supported with relevant student activity data, students' critical thinking skills increased with the average N-gain on the interpretation indicator is 0.78; analysis indicators of 0.83; indicator of inference of 0.74; and evaluation indicators by 0.84 with high criteria. In addition, student learning outcomes also reached classical completeness of 88.57%.

Abstract

An initial survey showed that some chemistry teachers at the MGMP of Mojokerto Regency and City had never attended argumentation skills training. Argumentation skills are important to practice as an effort to improve critical thinking skills, improve understanding and problem solving. This activity aims to improve the understanding and skills of chemistry teachers in Mojokerto in developing argumentation-based evaluation questions. This activity was carried out in two sessions through six stages of activities starting from preparation, training, monitoring, implementation, evaluation, and appreciation stages. The results showed that the development of teachers' understanding related to argumentation skills was analyzed using the N-Gain score and the majority were in the moderate group. The results of the question development also showed an increase in the level of argumentation skills. The response questionnaire showed that all teachers supported this PKM activity and the activity had been 100% implemented. This activity is expected to be one of the triggers for teachers to make their students more critical, creative and able to solve problems well through argumentation skills training.
