Question in Panamaconferentie
1) Randomiseer een waarde, bijvoorbeeld de prijs, en pas alles aan zodat het automatisch werkt.
Een nuttig commando is
precround(...,2)wat een getal op 2 cijfers na de komma afrondt.2) Randomiseer alle waardes. Het ideaalst lijkt mij het aantal initiële appels, de prijs van toen, en hoeveel appels je finaal zou kopen. Je kan dit doen door een lijst van goeie opties manueel in te geven, of door automatisch een goeie situatie te selecteren (moeilijker).
Een nuttig commando is
gcd(a,b)wat de grootste gemene deler geeft van 2 getallen (voor de middelste kolom in de verhoudingstabel). -
Question in Panamaconferentie
1) Schrijf een modeloplossing. Houd rekening dat je bij randomisatie dit anders zal moeten schrijven.
2) Randomiseer de snelheid, en controleer welke effecten dat heeft op de andere variabelen.

Question in Panamaconferentie
1) Voer de vraag zelf uit als leerling
2) Randomiseer deze vraag. Vervang de concrete getalletjes door willekeurig getrokken variabelen, maar zorg dat de vraagstelling en modeloplossing nog mooi eruit zien.
3) Controleer of de willekeurige getallen altijd even moeilijk zijn, of de randomisatie soms significant moeilijker is. Indien ze moeilijker is, beperk die gevallen bij Variable Testing.

Question in MfEP Progress Quizzes
Student is given a rational function, h(x), with randomised coefficients, and a linear function, k(x), also with randomised coeffieients and asked to find:
- h(k(x)) or k(h(x)) (randomly selected) for a randomised value of x
- The domain of h(x) - multiple choice part
- A general expresion for k(h(x)) or h(k(x)) - opposite combination to first part.
Variables are constrained so that h(x) is not a degenerate form and that when evaluating h(x) denomiator is not 0.

Question in MfEP Progress Quizzes
This question gives the student the formula for the charge on a capacitor as a function of time then asks them to find the value of k, the exponential constant given other values and hence write out the formula for the given case. A custom function (in Extensions & scripts) extracts the student's formula and plots it on a JSXGraph object in the question. The student is then asked to evaluate the function at a given point using the plot or other methods. The value of the capacitor (Q_0), time (t) and charge at time t are randomised as is the value at which the formula is to be evaluated.
