The Validity of Worksheets Based on Toulmin's Argumentation Pattern (TAP) on Alternative Energy Materials to Improve Students' Critical Thinking

Abstract

This study aims to analyze the results of worksheet-based validity Toulmin’s Argumentation Pattern (TAP) to improve critical thinking skills on alternative energy materials. The method used in this study is the R&D method with the ADDIE development model. In this study there are three stages used, namely the analysis stage (analyze) namely determining the needs of students regarding alternative energy material worksheets, the design stage (design) namely planning the developed worksheet, and the development stage (development) namely preparing worksheets and conducting validation. The validity of worksheets is assessed using a Likert scale. The aspects assessed in the validity of the worksheet are the didactic, constructive and technical aspects. The analysis technique was carried out by calculating the results of the validity of the worksheets from 3 validators consisting of 2 expert lecturers and 1 high school teacher. The advantages of this worksheet are that it uses the PBL learning model, based on TAP, contains authentic problems, and trains indicators of critical thinking. The drawback is that worksheets are not yet digital based. The main advice from the validator is to pay attention to critical thinking indicators and the TAP components used. The results showed that the average validity value of the three validators on the didactic aspect was 94.2% with very valid criteria, on the constructive aspect a value of 100% was obtained with very valid criteria, and the technical aspect obtained a value of 91.7% with the criteria very valid. Based on these results it can be seen that the average value of the validity of the worksheet as a whole is 95.3% with very valid criteria. So, it can be concluded that the worksheet is based on Toulmin’s Argumentation Pattern (TAP) to improve critical thinking skills on alternative energy materials suitable for use in the learning process.
