Abstract
Scientific reasoning skills are essential abilities in decision-making to avoid panic behaviour while increasing critical thinking skills. Project-based learning can empower scientific reasoning skills among students by presenting content within authentic projects. This study aims to determine the effect of a project-based learning-assisted genetics 1 project guide interactive e-book on the empowering reasoning skills of Biology students at the Faculty of Mathematics and Natural Sciences, State University of Malang. The study involved 63 students who were taking the Genetics 1 course. The research method was quasi-experimental with a nonequivalent control group pretest-posttest design. The instrument used to measure scientific reasoning is a test consisting of five questions whose validity and reliability are known well. Indicators of scientific reasoning consist of abilities in these aspects: (1) argumentation or topic selection- (2) knowledge, research, and views- (3) methodology- (4) analysis- and (5) conclusions, limitations, and implications. The data obtained were then analyzed descriptively and continued with one-way ANCOVA. The results showed a significant difference in students^ reasoning in learning that started with PjBL+e-books and PjBL only. Furthermore, the experimental class reached the highest corrected average (PjBL+E-book), 83.204, while the control class had a corrected average of 57.522. Therefore, the PjBL model-assisted e-book can be used as an effort to empower students^ scientific reasoning.
