Promoting Creative Thinking and Communication Skills Through Project-Based Science Learning on Nutritional Exploration of Traditional Indonesian Foods
Abstract
This study investigated the effect of a Project-Based Learning (PBL) model incorporating ethnoscience content, specifically the traditional food Legomoro, on students' creative thinking and communication skills. Using a quantitative quasi-experimental design with an unequal control group, this study was conducted on eighth-grade students at a junior high school in Magelang City. Two classes participated: Class VIII A (experimental, 31 students) and Class VIII B (control, 31 students), which were selected using purposive sampling. Data were collected through tests and observation sheets, including pre-tests and post-tests for creative thinking, as well as observation and self-assessment for communication skills and observation of learning implementation. Data were analyzed using descriptive statistics, inferential statistics, and MANOVA with SPSS 26.0. The results showed significant differences between experimental classes and demonstrated a strong influence of ethnoscience-loaded PjBL on students' creative thinking and communication skills regarding the traditional food 'Legomoro.' This study emphasizes the importance of selecting the appropriate learning model, offering valuable insights for educators to enhance their teaching practices by incorporating local cultural contexts and fostering 21st-century skills.
