Abstract

The increasingly complex issue of environmental change requires students to possess critical thinking skills in order to understand and find solutions to the ecological problems occurring around them. Learning activities in schools still tend to focus on rote memorization, which limits students’ ability to think deeply and analytically about environmental phenomena. The Problem-Based Learning (PBL) model emerges as an innovative student-centered approach that presents real-world problems to be solved through critical and collaborative thinking processes. The purpose of this literature review is to analyze the influence of the PBL model on enhancing students’ critical thinking skills in understanding environmental change issues. Based on the review of previous studies, PBL has been proven effective in improving critical thinking ability, conceptual understanding, and awareness of environmental issues. Therefore, the implementation of PBL can serve as a relevant learning strategy to develop active, reflective students with a high level of ecological awareness.

Abstract

Moss plants (Bryophyta) are bioindicators of environmental pollution. Identification of moss plant diversity has never been carried out at Medan State University. The research design used to obtain field data is by using the exploratory method. Sampling was purposive sampling in the humid environment around Medan State University, especially in parts that have lots of trees. The results obtained in this study show that there are two types of moss plants, namely leaf moss and liverworts. There are three species of leaf moss found, namely, Sphagnum moss, Entondon seductrix, Andreaea rupestris while the liver moss found is the Bozzania trilobata species.
