Improving Critical Thinking Skills To Learn Heredity With Discovery Based Unity of Sciences (DBUS) Model

Abstract

The Background of this research is the study of the integration of science and religion in science learning in Islamic Higher Education. The study discusses how to teach biology with Discovery Based Unity of Sciences (DBUS) model to improve students’ critical thinking skill. Observation of research at UIN Walisongo and UIN Sunan Kalijaga. Classroom learning uses a discovery based Unity of sciences (DBUS) model. Samples in the study were 96 students of UIN Walisongo and 94 students of UIN Sunan Kalijaga in first year 2017/2018 and 2018/2019. The research used experimental method with T test pre-test post-test experiment. The N-gain obtained by the experimental class is 0.23 is greater than the control group of 0.09 in UIN Walisongo. The gain obtained from the experimental class is 0.54 greater than the control group 0.16 in Sunan Kalijaga UIN. The results of the DBUS model study are feasible to improve critical thinking skills of heredity learning. Content validity between 0.75 to 1.00. Construct validity using Structural equetion model (SEM) method with lisrel analysis 8.7 with loading factor value of all critical thinking skill 0,575 and T-value of DBUS model> 1.96. The effectiveness of DBUS model with statistical test at UIN Walisongo Semarang by value of t value = 9,326 with sig 0,000 <0,05 and UIN Sunan Kalijaga obtained t value = 25,582 with sig value 0,000 <0,05.
