Model Based Reasoning by Introductory Students When Analyzing Earth Systems and Societal Challenges Lauren Holder (lnholder@tamu.edu), Bruce Herbert (herbert@geo.tamu.edu) Department of Geology & Geophysics, Texas A&M University, College Station, TX 77843 Abstract Instructional Design and Activities and Rubric Understanding how students use their conceptual models to reason about societal challenges involving societal issues such as natural hazard risk assessment, environmental policy and management, and energy resources can improve instructional activity design. This can improve student motivation and earth science literacy. To address questions of student conceptual modeling, we created four laboratory exercises for introductory physical geology using situated cognition theory that engages students in authentic scientific practices and design within the context of significant sociotechnical issues facing society. Our case-study design allows us to investigate the various ways that students utilize model based reasoning to identify and propose solutions to societally relevant issues. Student reviews material from laboratory manual prior to class Quiz on material Short introduction to topic (PowerPoint) Student interpret and graph data Graphing Data Student draws/writes conceptual model Student answers societally relevant questions or suggests solutions to societal grand challenges Rubric Exploratory Analysis Time and Scale (3 points) Time and Scale (1 point) Interpreting Data System Processes (3 points) Science, Technology, and Society System Processes (1 point) Cognitive Apprenticeship Mental Model Model Based Reasoning Conceptual Model Problem solving through Design STS Issues Emotional Ideologies Naïve Conceptions Place-Based Learning with Authentic Data “Building students’ appreciation for the integration of science, technology, and society is based on the problems and situations that they examine or experience both inside and outside of the classroom” (College Board). Anecdotal Evidence • A Evidence Based Claims 2 points Rubric Category 3 points 2 points 1 point Explanation of System Processes Successfully identifies and separates processes, mechanisms, and components of a system. Identifies and explains relationships between processes and components. Student can identify processes, mechanisms, or components of the system but not all. Students model may identify Student does not complete one process, mechanism, or model. component of the system. Explanation of Scale and Time Identify and explain relationships, processes, and characteristics that change over time, can be cyclical in nature, and differ with respect to space, size, and location (when applicable). The student addresses both scale and time, but does not completely explore changes in space, size, location The model displays incorrect, poorly drawn, or naive conceptions about scale and time for processes and characteristics in the system or does not address either scale or time. Student does not complete model or does not show changes in scale or time for processes or characteristics in the system. Model Justifications Student uses evidence in their model and correct terminology and concepts. The student uses adequate evidence in their model; however, the student may use incorrect terminology and may demonstrate naïve conceptions about the system. The student does not draw a model or does not use evidence in their model or demonstrate any understanding of the material including a lack of terminology. EvidenceBased Claims The student uses evidencebased claims from the conceptual model or other parts of the laboratory to answer societally relevant policy, management decisions, or grand challenges. Anecdotal evidence and emotional ideologies are kept to a minimum. The student uses evidence-based claims from the conceptual model or other parts of the laboratory, but uses considerable anecdotal evidence and emotional ideologies to solve grand challenges. The student relies heavily on prior knowledge or past experiences, but still uses some evidence in their model. The student may also demonstrate naïve conceptions, incorrect terminology, and incorrect assumptions. The student does not use evidence-based claims and instead uses anecdotal evidence and emotional ideologies. 1 point 0 points The student does not answer any question regarding societal issues or grand challenges.
