The representation is an animated slide show which:
-describes a distance-time graph
-explains what the slope of a distance time graph represents
-explains its usefulness in understanding an objects motion
This resource also includes an interactive test and review of the material, and can be downloaded for offline use.

The resource addresses the actual substance of the learning goal rather than
just the topic.
This resource explains how an cyclist's position, motion and speed can be measured and represented on a graph.
The resource addresses the entire learning goal.
An object’s position and motion can be represented on a graph.
The resource correctly reflects the level of sophistication of the learning
The level of sophistication of this resource is appropriate for middle school students. The slide describing the calculation of slope for position-time graphs includes calculations that may be above the expected level of sophistication for middle school students.
Notes for Teachers
De-emphasize the calculations of slope shown within the slide show, instead emphasizing the qualitative differences between steeper and shallower lines on these graphs.
Quality of instructional support
Does the representation accurately represent relevant aspects of the learning goal and/or brings out limitations that are not accurate?
Yes—The representation accurately represents relevant aspects of the learning goal and brings out inaccuracies, if there are any.
This resource accurately describes how a distance time graph represents the position, direction of motion and speed of an object. It does show (and explain) how a difference in slope represents a difference in speed.
Is the representation likely to be comprehensible to students?
Yes—The representation is likely to make the learning goal comprehensible to students.
There are no inaccuracies that would hinder a students comprehensibility of this resource.
Does the representation make clear which aspects of the real thing are represented and which are not?
Yes—The representation makes clear which aspects of the real thing are represented and which are not.
The graphs are accurately drawn and the drawings are accurate representations of the actual objects being discussed.
Notes to teachers
This resource presents a fairly basic, direct instruction approach to the learning goal. Teachers may wish to use this resource as a review of the topic or supplement it with in-class experiences graphing objects moving at a constant velocity.
