Return to Question 4

There are a number of fundamental rules for designing computer-based instruction and interfaces.List four of these,and for each one,explain why it is important.

Any four from the following;one mark for the point,andone for a relevant comment about its importance.

1.Keep cognitive load low
2.Avoid dividing the learner ’s attention
3.Use colour,arrows,shading,and sound sparingly.
4.Keep visible on-screen the information learners need to refer to during instruction.
5.Clear learners ’working memories by encouraging frequent rehearsal.
6.Encourage dual encoding by using concrete words and different media.
7.Avoid repetition in interactions.
8.Encourage encoding specifically through high-fidelity simulation practice.

What is the purpose of outlining?Describe how to create an outline.

To identify and define the branching of the program (1).

Awardmarks for points such as:

Developing an outline for an interactive multimedia project is like developing an outline for an essay (1).The outline structure translates into branches or points of decision on the screen (1).Major headings in the outline become options for the user (1)

(c)Why is the logic flow chart important in developing a multimedia application?

Graphically the logic flow chart provides a road map of the proposed application (1). The flow chart illustrates the choices that the application user has for each screen (1).It is important that the logic is developed correctly so that the project is developed properly (1).
