This study was an initial exploration into replacing textual ASSISTments feedback with matched content videos. It is related to Rich Mayer's Multimedia principles.
This study uses:
- Stand alone problem set (using the choose condition).
- A problem set where there is a set number of problems.
- Using the scaffold response.
The Problem Set
A choose condition is used
Each student sees a total of 11 problems, 6 of them are Pythagorean Theorem problems.
This problem set starts with a linear section. The ID for this problem set is PSAHVAN in case you want to make a copy and take a closer look. There is an introduction about setting the volume on the computer to be ready for the video. Then comes the experiment which has a choose condition. Finally there are 4 survey questions.
There were 4 conditions with different orders of video and text. Note how the Choose Condition is evoked fro this section. The published study used Group 1 and 3 as one condition (video first) and Group 2 and 4 (text first) . The first problem was experiment and the second problem was the assessment of the experiment.
You can see here how group 2 was set up in linear order.
The ConditionsScaffolding is used to deliver the text and the video feedback.
