Abstract

Critical thinking ability is one of the important competencies that students must possess in biology learning. This research aims to develop Problem-Based Learning (PBL) Student Worksheets to train students' critical thinking skills in Plant Anatomy courses. This research uses the Research and Development method with a simplified 4-D model consisting of three stages: Define, Design, and Develop. The research subjects were second-semester Biology Education Study Program students at Universitas Muhammadiyah Bengkulu. Research instruments included media and material expert validation sheets, as well as student response questionnaires. Validation was conducted by one media expert and one material expert, then tested on 5 students (limited trial) and 22 students (extensive trial). Validation results showed that the student worksheets received a "very valid" category with 86% from media experts and 88% from material experts. Practicality tests showed "very practical" results with 89% in limited trials and 91% in extensive trials. The developed student worksheets contained contextual problem scenarios, systematic PBL stages, and critical discussion questions that encourage students to analyze, evaluate, and conclude based on empirical data. This research concludes that PBL-based student worksheets are feasible to use as learning media to train students' critical thinking skills in Plant Anatomy courses.

Abstract

Mathematical literacy is one of the abilities that students must have. Mathematical literacy skills include the ability to use, create, review, and utilize information to solve problems based on their mathematical knowledge and skills. This study aims to analyze the effect of Project Based Learning learning model assisted by GeoGebra on students' mathematical literacy skills. This research was conducted at one of the public junior high schools in Bekasi in the 2024/2025 school year. The research method used is Quasi Experimental Design with posttest control group design. The sample used consisted of 34 experimental class students and 34 control class students. Data collection on mathematical literacy skills using test instruments in the form of eleven description questions that have been tested for validity, reliability, differentiating power, and difficulty level. The indicators of mathematical literacy skills studied were formulate, employ, and interpret. The results showed that the mathematical literacy skills of students taught with the GeoGebra-assisted Project Based Learning learning model were higher than the mathematical literacy skills of students taught with the Direct Instruction model. In addition, the results of this study indicate that the GeoGebra-assisted Project Based Learning model can be recommended to facilitate students' mathematical literacy skills.
