Abstract
Critical thinking skills are referred to as one of the 21st-century skills. These skills should be empowered through Biology learning. This study aims to analyze the improvement of biology-critical thinking skills in students who are taught through the CIRC learning model based on the scientific approach (Cirsa). Critical thinking skills are measured by tests developed by researchers and validated by theoretical biologists. The instrument includes indicators of critical thinking skills such as formulating problems, giving arguments, making deductions, conducting inductions, conducting evaluations, and deciding and implementing. This study used a quasi-experimental method with a pretest-posttest non-equivalent control group design. This study involved 160 students (M = 95, F = 65) of 8th grade of a Madrasah Tsanawiyah School in Bogor. The findings of this study show that students who are taught by Cirsa have higher Biology-critical thinking skills than those by conventional learning. In conclusion, Cirsa learning was recommended to develop or enhance students' critical thinking skills related to biological concepts.
Highlights
Biology education, especially in anatomy and physiology learning, is essential in developing scientific knowledge among students [1,2]
The research aimed to find out the influence of Cooperative Integrated Reading and Composition (CIRC) and Cirsa learning models on critical thinking skills on human excretion and respiratory systems
Based on the research findings, it can be inferred that the Cirsa learning model has proven to be more effective in enhancing critical thinking skills on human excretion and respiratory system
Summary
Especially in anatomy and physiology learning, is essential in developing scientific knowledge among students [1,2]. Anatomy and physiology are knowledge related to constituent organs and their function for an organism, including the work mechanism process [3,4]. The 2013 Curriculum applied in Indonesia includes topics on constituent organs and their functions, work mechanism, and disruptions occurred in an organism [7,8,9,10]. Studying biology should not merely focus on knowledge related to the curriculum components. Various studies that empower critical thinking skills in Biology learning include [12,16,17,18,19]. It is proof that critical thinking skills are empowered through Biology learning
