Abstract

This study aimed to determine the effect of the application of Project-Based Learning (PjBL) model on students' science literacy skills at SMA Hang Tuah Tarakan. The study was motivated by the observed low levels of science literacy among students, attributed to a lack of exposure to tasks that require in-depth reasoning and critical thinking. Employing a quantitative approach with a quasi- experimental method, the study utilized a non-equivalent control group with a pretest-posttest design. The population consisted of all tenth-grade students at SMA Hang Tuah Tarakan, with purposive sampling used to select two groups: class X-A and class X-C, comprising a total of 52 students. Data on science literacy were collected through a multiple-choice test instrument. Data analysis included prerequisite testing (normality and homogeneity tests), hypothesis testing, and N- Gain testing to measure improvement. The hypothesis was tested using an Independent Sample T-Test, which revealed a significant difference in science literacy skills between the experimental and control groups, with a Sig. (2-tailed) value of 0.020, which was less than the significance level of  = 0.05. These findings demonstrated that the application of the PjBL model had a positive effect on enhancing students' science literacy skills.

Abstract

The history of science plays an important role in science teaching and learning. This is because the history of science consists of meaningful information related to scientific processes and concepts. This study implemented a historical episode of photosynthesis discovery conducted by Ingenhousz as a learning resource for learning photosynthesis. A single case study was implemented in this research aimed at finding the role of the history of science in student understanding of science concepts and scientific literacy skills of preservice Biology teachers. The data was collected through summative evaluation tests, interviews, and document collection. The results show that the preservice biology teachers understand photosynthesis concepts and scientific literacy in all dimensions. Therefore, it can be concluded that the history of photosynthesis discovery contributes positively to preservice Biology teachers’ understanding of photosynthesis concepts and scientific literacy.
