Saved a checkpoint:
I've changed the definition of x2 to make sure the sales are always non-negative.
J. Richard Snape commented 7 years, 1 month ago
Part (b) uses the random variable n={0..4}, but that can give negative sales in a year which doesn't make much sense. I think that the variable definition has been copied over from a different word type question and should actually be allowed to run {2..5}

Saved a checkpoint:
Part c was wrong in a few ways! Given the formula for converting from Celsius into Fahrenheit, it asked the student to convert a temperature in Celsius into Fahrenheit - the other way round. It looks like your definition of the variable T_F was also wrong.
I've fixed those, and the rest of the question looks good.

- Main parts
- You need a full stop at the end of the statement.
- You don't need a comma before the function of the curve in part a).
- I think part a) needs to be reworded a little. Maybe put the curve function first.
- Part b) is fine.
- You don't need a comma on the first line of part c). However, there should be one after the formula. There shouldn't be one after where on the third line.
- Advice
- It should be a full stop rather than a comma after "substitute 5 into 9x^2 +3x +22." in part a). Maybe reiterate that the final answer you get is equal to the y-coordinate.
- Same comments as above for part b). A full stop and reiterate that it is the predicted number of yachts sold.
- For part c), it should be a full stop at the end of the first line. Start the next line as a new sentence with a capital letter and end that line with a full stop. Reiterate that the final answer is the temperature in fahrenheit.
- Good questions and I like the contexts!

Hi Aiden,
- I think the way that you have written x=5 in the advice is the way you should write it in the questions. I think that would make it a little clearer. At first, it looks like x=5 is a continuation of the expression. I think this is probably better:
'At x=5,
what is the value of 4x^2+x+53?'
- You need to say in part c) that the user is to use pi=3.142. You did it for part e) but not for part c). I did the question using my calculator pi button as you hadn't specified using any simplification, and the answer I gave was marked incorrect due to different rounding. I then had to use the same answer when finding the volume of the cone and it accepted my answer that time, when multiplied with h/3 so it is only a problem for part c).
- You have the radius, 'r' written in LaTex in part c), but not in part d).
- In part e), "Geraldine has a ball of radius 31.4cm // she wants to find the volume of the ball." doesn't make sense. You're missing a full stop and a capitalisation, or an and. Also, I think the next sentence should be on a separate line personally.
- I don't know if it is automatic, or whether you can change it, but your rounding requirements in part c) and d) are specifying 1 decimal place - singular, but saying "Round your answer to 1 decimal places" - plural.

In the equations for volume, the word volume itself should be in roman.
The first part of the prompt to part (e) doesn't make sense, and the second part needs a comma after "Using the below equation".
Some additional punctuation of equations is required in the advice. And where you have in small, italic, "Rounding your answer to 1 decimal place", there is no need for this to be either small or italic in the advice. Grammatically, you've also gone from first person (plural) to second person.

For each combination of answer and choice, specify the number of marks to add or subtract when the student picks it.
For each combination of answer and choice, write 1 if the student should tick it, or 0 if they should leave it unticked.
Test that the marking algorithm works
Check that the marking algorithm works with different sets of variables and student answers using the interface below.
Create unit tests to save expected results and to document how the algorithm should work.
There's an error which means the marking algorithm can't run:
This is an extension type part. There is no expected answer, and it's assumed that the marking depends on interactions within the part's prompt.
You can test this part's marking algorithm by interacting with the rendering of the part's prompt below.

When you need to change the way this part works beyond the available options, you can write JavaScript code to be executed at the times described below.
To account for errors made by the student in earlier calculations, replace question variables with answers to earlier parts.
In order to create a variable replacement, you must define at least one variable and one other part.
| Variable | Answer to use | Must be answered? | |

The variable replacements you've chosen will cause the following variables to be regenerated each time the student submits an answer to this part:
These variables have some random elements, which means they're not guaranteed to have the same value each time the student submits an answer. You should define new variables to store the random elements, so that they remain the same each time this part is marked.
This part can't be reached by the student.
