Students’ Scientific Literacy as the Effect of Project-Based Learning Using a Simple Colloid Product

Abstract

Scientific literacy is still to be a problem for most worldwide students, including in Indonesia. This study used simple colloid products as a learning source in a project-based learning setting to train students' scientific literacy. The nonequivalent control group design research was applied in two different classes of grade 11 SMAN 4 Banjarmasin involving 69 students. Data collection used scientific literacy test instruments that are valid (CVR index of 1) and reliable (αCronbach index of 0.91). Research data were analyzed by using descriptive and inferential t-test methods. The measured scientific literacy competencies include explaining scientific phenomena, evaluating and designing scientific research, and interpreting data and scientific evidence. This study concluded that the students’ scientific literacy of project-based class was better than the expository class by good and moderate category. Exploring more sources of learning chemistry from industrial products is necessary to generate scientific awareness that chemistry helps build our real life. At the same time, it will produce meaningful learning to form scientific literacy.
