The Interface of Exercise 3.

This exercise tests the student's judgement in measuring the intervals between pitches in relation to the simulated DPL.

The design of this exercise is considerably more complicated than that of Exercise 1. You will observe an annotated facsimile, instructions, 14 answer boxes into which the student can enter intervals, two buttons and a feedback box.

Before the student is able to check the answer, he/she must first enter an interval into each of the answer boxes. There are a number of issues here. First, the exercise has been designed to prevent the student from entering anything other than one digit into an answer box. Second, when the student clicks on an answer box, the associated annotation on the facsimile is highlighted in blue.

When the exercise has been completed correctly, and the student checks the answers, the buttons disappear and the feedback box offers congratulations. If some intervals are wrong, the feedback box will show how many are correct.

At this point, it will not be possible for the student to alter any of the intervals that are correct. If the student gives up, the correct intervals are displayed below the answer boxes. Intervals that are incorrect will be highlighted in red. By doing this, the student becomes aware of the intervalic distances he/she finds awkward to calculate.
