Ananda Ayu Kurniawati — 2023-07-31

The purpose of this research is to make an evaluation tool for critical thinking skills related to the subject matter of the respiratory system. This study used a research and development approach using the Planning, Production, and Evaluation (PPE) framework. The research process consists of three fundamental stages, namely the planning stage, the production stage, and the evaluation stage. The assessment instrument has gone through a validation process involving three validators. Assessment of the validity of the material consists of five aspects that must be examined, one of which is related to the suitability of the questions with indicators of critical thinking. The material validity assessment shows a validity value of 100% which indicates the ability of the instrument to measure the material in question accurately. The assessment of the construction aspect consists of eight aspects that must be reviewed resulting in a validity value exceeding 75% for each item indicating that the developed instrument meets the validity criteria. The assessment of the language aspect which consists of five aspects that must be studied produces a validity value that exceeds 75% for each item so that it shows the validity of this instrument. This shows that the evaluation tool in the form of an assessment instrument for critical thinking skills that has been developed can be declared valid for evaluating critical thinking skills in the material on the respiratory system.

MIND MAPPING : PERLUKAH DITERAPKAN UNTUK MENCAPAI PEMAHAMAN KONSEP?

Amanda Salsabila Ilhami — 2023-07-31

Pre-research activities show low student’s learning outcomes on human respiratory system material. This is due to not achieving concept understanding according to predetermined learning indicators. The solution formulated is to train cognitive learning strategy in the form of mind mapping to help the learning process. The mind mapping strategy can facilitate the achievement of concept understanding indicators at the Bloom’s Taxonomy cognitive level, so it was chosen as a solution to overcome the problem. The purpose of this study was to determine the effectiveness of mind mapping strategy in improving students’ concept understanding. The type of research used is pre-experimental with a one-group pre-test and post-test design. The research subjects involved 32 students from VIII–F class at a SMP in Sidoarjo. The results showed that the mind mapping strategy was effectively used to improve students’ concept understanding as shown by the acquisition of the t_statistics > t_table value, namely 12.440 > 2.036 and the n-gain value of 0.70 with high criteria. Based on these results, it can be concluded that the implementation of mind mapping learning strategy can improve students’ concept understanding.
