## Acceleration

The Acceleration Concept Builder is comprised of a bank of 60 questions that are delivered to the learner across three different activities. Each of the three activities has a slightly different emphasis. The first activity - To Acclerate or Not To Accelerate - challenges learners to use the acceleration concept to determine when an object accelerates or doesn't accelerate. The second activity - Getting Direction on Acceleration - assesses the learner's ability to determine the direction of the acceleration from information about its direction of motion and whether it is speeding up or slowing down. The third activity - Adding Value to Acceleration - challenges students to calculate the numerical value of acceleration from simple numerical data. Questions are grouped with questions in the same group rbeing very similar. If a learner misses a question within Question Group 1, then another question within the same group will be presented to the learner at a later time.

The three activities in this Concept Builder are summarized as follows:

• To Acclerate or Not To Accelerate: Question Groups 1-6
• Getting Direction on Acceleration: Question Groups 7-14
• Adding Value to Acceleration: Question Groups 15-20

The questions and images used in this Concept Builder are shown below. Teachers are encouraged to view the questions in order to judge which activity is most appropriate for their classes.
