Two experiments were performed to study the effects of varying the exposure-time and the dissolve-time in the use of a lap-dissolve control unit in presenting programmes intended to teach 14-15-year-old students to visualise the effects of performing reflections and rotations on molecules represented in diagrams. Both experiments employed a two-dimensional design with three levels for each of the two factors. The Rotations Programme was not effective with any of the combinations of exposure- and dissolve-times. The effectiveness of the Reflections Programme showed a significant U-shaped relationship as the exposure-time changed from 5 through 7.5 to 10 seconds. There was no significant effect involving dissolve-time. |
