Abstract

Critical thinking skills are one of the abilities needed by students to face the challenges of the 21st century. This study aims to describe the validity of Higher Order Thinking Skills (HOTS)-based questions developed to train students' critical thinking skills. This research used a developmental research model (ADDIE) model. The parameter measured was the product's validity level, consisting of HOTS-based questions, using a validation instrument involving two validators: a material expert and a learning device expert. The subjects in this study were 11th-grade high school students. The questions were developed in essay format and presented through the digital platform Quizizz as a learning evaluation medium. The validation results showed that the questions fell into the appropriate to very appropriate category, with a percentage range of 62.50% - 81.25% for the material aspect, and 81.25% - 100% for the learning device aspect. Thus, the developed HOTS-based questions are deemed appropriate for use in learning evaluation activities and have the potential to support the development of students' critical thinking skills.

Abstract

Critical thinking is an important component in 21st-century Biology education, which demands the ability to critically analyze scientific concepts and information. However, students' critical thinking skills are still relatively low. This study aims to describe the profile of critical thinking skills of eleventh-grade students at a high school in North Sulawesi on the human digestive system. The method used is a quantitative approach with a descriptive design. The sample consisted of 19 randomly selected students. The research instrument was a test developed based on five critical thinking indicators according to Ennis, providing simple explanations, building basic skills, concluding, providing advanced explanations, and developing strategies and tactics. Data were analyzed descriptively quantitatively by looking at the percentage of achievement in each indicator. The results showed that most students' critical thinking skills were in the low category. As many as 74% of students were very low in providing simple explanations, and 89% were in the very low category in the advanced explanation indicator. The highest achievement only reached the sufficient category. These findings indicate that conventional Biology learning practices have not been able to encourage the development of critical thinking skills optimally. Therefore, this study emphasizes the importance of implementing profile-based diagnostic assessments and integrating active, contextual learning strategies that are oriented towards higher-order thinking skills in Biology learning.
