Thinking about actions to take: Speed

There's a good chance you could improve your teaching if you were to:

Try these

• speaking about duration and distance in order to calculate speed
• using full quantity algebra when calculating speeds
• relating calculations on speed to useful examples
• always being careful about specifying differences (in position, or in clock time) in order to calculate speeds

Teacher Tip: Work through the Physics Narrative to find these lines of thinking worked out and then look in the Teaching Approaches for some examples of activities.

Avoid these

• uncritical use of the word time
• achieving fluency at the expense of understanding

Teacher Tip: These difficulties are distilled from: the research findings; the practice of well-connected teachers with expertise; issues intrinsic to representing the physics well.
