This activity for conceptual physics asks students to predict the appearance of distance and velocity graphs for different types of walking motion, then verify their predictions with a motion sensor. If all members of the cooperative group predict correctly, the group moves to the next problem. If not, the group's task is to analyze the error to see what went wrong, then write statements about how to modify incorrect ideas to avoid the same mistake in the future. For accompanying homework problems: Catching Mistakes: Motion Graphs Homework (UMPERG) This resource was developed by the University of Maryland Physics Education Research Group (UMPERG). It is based on Tools for Scientific Thinking, a microcomputer-based laboratory curriculum for student development of concepts and intuition in the laboratory.

Write arguments focused on discipline-specific content.

Use functions to model relationships between quantities.

Describe qualitatively the functional relationship between two quantities by analyzing a graph (e.g., where the function is increasing or decreasing, linear or nonlinear). Sketch a graph that exhibits the qualitative features of a function that has been described verbally.

Create equations that describe numbers or relationships

Create equations and inequalities in one variable and use them to solve problems. Include equations arising from linear and quadratic functions, and simple rational and exponential functions.

Interpret functions that arise in applications in terms of the context

For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship.?

Understand and evaluate random processes underlying statistical experiments

Decide if a specified model is consistent with results from a given data-generating process, e.g., using simulation.
