Subduction Zone

Content/concepts goals for this activity

The goal of this activity is to evaluate whether students understand where earthquakes would occur in a cross-section view (content skill).

Higher order thinking skills goals for this activity

Not applicable

Audience

Students in an introductory-level geoscience course.

Skills and concepts that students must have mastered

Students should know that earthquakes can occur at plate boundaries and that earthquakes occur where the plates touch in the subsurface.

How the activity is situated in the course

This activity is used as a formative assessment question following a lecture or activity about plate tectonics and plate boundary features. Displaying the results after administering the question provides students and instructor immediate feedback.

Using a technology-enhanced formative assessment (TEFA) approach, if the pattern of responses lacks consensus, engage the students in peer discussion about the answer (Beatty and Gerace, 2009). Allow students to "revote" for their answer after a brief discussion. If there is not convergence on the scientifically accurate answer, then engage in re-teaching the concept.

Science of Learning: Why It Works

There is accumulating evidence that engaging in spatial prediction and receiving feedback about the nature of one's errors leads to improved spatial reasoning (Gagnier et al. 2017; Resnick et al., 2017). Making a prediction, receiving feedback, and learning from the mismatch between the expected and actual outcomes is a process studied in cognitive science called the delta-rule model of learning (Rescorla and Wagner, 1972). Modern models of learning from the education research literature focuses on Piaget's concept of accommodation, where people will adjust their mental models as a consequence of the the feedback (Dole and Sinatra, 1998). Examples from research on geology concepts show us that students' build more scientifically accurate mental models after engaging in prediction and feedback. Gagnier et al. (2017) engaged students in making predictions about the interior of a geologic structure using block diagrams. The cycle of prediction and feedback facilitated students improved performance on a test of penetrative thinking. Resnick et al. (2017) engaged students in making predictions about the geologic time scale using a classroom response system (clickers). Students answered multiple-choice questions about the position of geologic events on a typical diagram of the geologic time scale. The spatial prediction clicker questions were as effective as, and more efficient than a hands-on meter stick activity at building a scientifically accurate linear conception of geologic time. Building on this research, we propose that the technique described below is a useful approach to identify students' spatial conceptions associated with various geologic phenomena (LaDue et al., 2021; LaDue and Shipley, 2018).

Using a technology-enhanced formative assessment (TEFA) approach, if the pattern of responses lacks consensus, engage the students in peer discussion about the answer (Beatty & Gerace, 2009). Allow students to "revote" for their answer after a brief discussion. If there is not convergence on the scientifically accurate answer, then engage in re-teaching the concept.

This question is useful for students to self-assess where their answer fits relative to other students in the class. Top Hat displays student responses in a heat map image that highlights the most common answers. In most systems it is possible to designate a region for the correct answer, but receiving a right-wrong answer is likely less useful than engaging students in peer discussion if the students' responses do not converge on one region.

Resources: There are several systems that offer click-on-diagram questions. The one we used is: https://tophat.com
