This tutorial 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.

This tutorial 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.

6-8: 4F/M3a. An unbalanced force acting on an object changes its speed or direction of motion, or both.

9-12: 4F/H8. Any object maintains a constant speed and direction of motion unless an unbalanced outside force acts on it.

9. The Mathematical World

9B. Symbolic Relationships

6-8: 9B/M2. Rates of change can be computed from differences in magnitudes and vice versa.

6-8: 9B/M3. Graphs can show a variety of possible relationships between two variables. As one variable increases uniformly, the other may do one of the following: increase or decrease steadily, increase or decrease faster and faster, get closer and closer to some limiting value, reach some intermediate maximum or minimum, alternately increase and decrease, increase or decrease in steps, or do something different from any of these.

9-12: 9B/H4. Tables, graphs, and symbols are alternative ways of representing data and relationships that can be translated from one to another.

Unique approach based on a prediction model of learning. Students 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 group predict correctly, they move to the next problem. If not, the group's task is to analyze the error to see what went wrong, then write statements to modify incorrect ideas. Lesson was designed using evidence from physics education research (PER).

This digital graphing activity accepts user inputs in creating "prediction graphs", then provides real-time animations of the process being analyzed. Learners annotate graphs to explain changes in motion.
