The Validity of Clues is Practical on Human Sensory Materials to Improve the Critical Thought Skills of Learners

Abstract

The primary purpose of this study is to describe the design and validity of the teaching material of electronic practice through problem-based learning (PBL) to improve critical thinking skills. The type of research used is development or research and development (R&D) using the 4D development design by Thiagarajan (1974). The research subject researchers use as the validator expert is the lecturer and biology teacher of SMAN 3 Tuban. Research and development data collecting that researchers use is a validation sheet. The research data analysis USES descriptive and verifiable techniques from the study. The results show the validity of the electronic practical instructions in terms of content/material worthiness achieves an average of 80% in valid categories, terms of systemic worthiness achieve an average of 82% in valid categories, terms of language worthiness achieves an average of 80% valid categories, and in terms of eligibility scores an average of 77% valid categories. The overall validity score of the electronic practical clue developed by 79.75% valid categories.
