Using Problem-Based Learning (PBL) to Teach Geographic Information Science

Abstract

Geographic Information Science (GIScience) is a field of study that investigates the development and use of theories, methods, technology, and data for understanding geographic processes, relationships, and patterns (Mark, 2003). Students in the discipline learn the conceptual and technical implementation of Geographic Information Systems (GIS; the analysis, storage, visualization, and management of geographic data). However, GIScience undergraduates often struggle to relate GIS theory to technical practice. In particular, students have difficulty mastering GIS tools and software and they are not well-equipped to determine the series of processes/tools required to complete geoprocessing tasks without prompts. GIScience courses commonly provide students with detailed step-by-step instructions on how to execute various GIS tools in order to solve example problems but students are eventually expected to perform the same or similar problem-solving tasks without detailed instructions. This workshop focuses on how to teach the technical and problem-solving skills required in GIScience courses effectively by employing a problem-based learning (PBL) model. PBL is an active learning method that increases understanding and competency. The approach focuses on problem solving, self-directed learning, team participation and cooperation (Pawson et al., 2006). PBL encourages students to use critical thinking, engages their curiosity to solve real-world problems, and promotes inquiry and interest in the subject matter (Pawson et al., 2006). A PBL approach encourages students to collaboratively solve problems in GIScience by first identifying the general steps to solve the problem and then solve those problems by determining the tools needed to process the data to come to a solution (Melero, 2010). Incorporating PBL into GIScience courses enables students to solve a larger variety of problems, promotes stronger retention of skills and theory, and better prepares them for future professional opportunities and/or academic research.
