Abstract

During the Covid-19 pandemic in Indonesia, Project-based learning (PjBL) is one of the recommended learning models by the goverment to be applied to students. The PjBL learning model requires students to be able to solve problems through planning and implementing a structured project. This learning model is very interesting when combined with the STEM approach. This study aims to determine the effect of implementing PjBL-STEM on students^ scientific attitudes on the topic of Global Warming at State Junior High School 1 or Batang Tuaka Indragiri Hilir Riau Indonesia during the Covid-19 pandemic. This research is a quasi-experimental toward 36 seventh grade students in the 2021/2022 academic year. They were divided into two classes- the control and the experimental class. The research instrument is a student scientific attitude questionnaire, especially regarding students^ concern for the environment. The data were analyzed using a t-test. The results of the study show that the implementation of PjBL-STEM has a large effect on increasing student interest in STEM. The indicator of showing curiosity about issues related to STEM and considering a career in the STEM field were significantly different with a 2-tailed sig 0.00 (sig <0.05) between those 2 classes. At the indicator of awareness of environmental health problems show a significant difference with a 2-tailed sig of 0.010 and an effect size in the medium category (medium effect), while the indicators of student perceptions of environmental health issues are not significantly different (sig. 2-tailed 0.088 and 0.179) between those classes.
