Example of a hyper quiz.

Introduction #

This is an example of a quiz in which the answer to a question determines which question should follow.
When creating the quiz you must indicate that the quiz should be presented as a so-called hyper quiz. Or else the quiz will be presented as an ordinary quiz (which, by the way, may be an advantage when developing the quiz).

With hyper quizzes the learners get an extra stimulus to learn while answering the quiz. If a question is answered incorrectly a easier question may be presented. If a question is answered correctly a harder question may be presented. Using dynamic (conditional) hints the question to be presented may depend on the answer (when the latter is incorrect). Notice the empty fields to the right of Qstn_name_number_x.

In this quiz some of the answers must be formula expressions in QCmath using +, -,-* and / for arithmetic operations. Notice that answers must be expressions, not formulas with both a left and a right side.

Qstn_phrase_1 #

A train, T1, leaves the station A making for station B at the same time as another train, T2, leaves station B making for station A. Both trains run at a steady speed, T1 at 125 km/h (kilometers per hour), T2 at 145 km/h. The distance from station to station is 375 km.
How far has the train T1 traveled when they pass each other (state the answer as a number with four significant digits):

2 Right! You'll get a supplementary question.

Qstn_name_number_2

0 Right! But if you were in doubt as to whether the answer would be correct, answer the question again, but incorrectly.

Qstn_name_number_3

Qstn_phrase_3

Write a formula expression for the distance between the trains at time t (before they pass each other): [20].
Answer with a formula expression in QCmath.

Correct_answer_3

!qcmath 375 - (125 + 145)*t

Hints_3

4 You'll get an easier question.

Qstn_name_number_4

Qstn_phrase_4

How many kilometers has the train traveled after t hours? Answer with a formula expression (remember * for multiplication).

Correct_answer_4

!qcmath 125 * t

Hints_4

3 The correct answer is the product of 125 and t. Try again.
3 The answer is 125*t (or t*125, etc.)
3 You'll have to learn more about writing formula expressions, look into here or ask your instructor.

Qstn_name_number_5

Qstn_phrase_5

From the formula expression you can determine the time t, when the trains pass each other. State the value of t with four significant digits: []

Correct_answer_5

1.389+-0.001

Hints_5

5 The distance between the trains is obviously 0 when the trains pass each other, thus: 375 - (125 + 145)*t = 0, from which t can be computed.

1 We shall return to the first question.

Qstn_name_number_6

Qstn_phrase_6

How far is the train T2 from the station A at time t:

Correct_answer_6

!qcmath 375 - 145*t

Hints_6

The correct answer is 375 – 145*t.

5 You should now be able to answer the previous question(s) correctly.
