Saved a checkpoint:
I reworded the advice a little bit.
This is a good question  there's a nice progression from simple inequalities to more complicated.

Thank you Lauren, some good points here, I've made all of these changes.
Lauren Richards 4 years ago
 I don't think you should ask everyone to put their answers as fractions when they're not needed to be in that form. Maybe add a bit saying "where applicable" at the end.
 Remember to have full stops at the end of each section of your advice.
 I don't think you need the section describing that c) is a mix of a) and b). Just state what you have to do. Also, as you have it right now, there is a typo  in instead of an.
 Good to highlight dividing by a negative number in part d).
 Typo in part g) of the advice  "rearraniging" instead of rearranging.
 The advice for part g) is not quite right. the integer does not have the correct sign for the middle two sections of your workings then suddenly has corrected itself by the last line.

Thank you for the feedback. I have simplified the answers and added a drop down for the inequality signs (great idea by the way). I've also fixed the advice error.

In parts b), c) and d) the expected answer isn't simplified. I got $1$ for part b) but the answer displays as $\displaystyle\frac{3}{3}$. I agree that it's important to include questions that involve flipping the inequality sign as you have in parts d) and g), but my concern is that you have entered the correct inequality for the student and they may not notice that it has been switched around as their answer would be the same either way. I know you've highlighted this in the advice but if the student gets their answer marked right, they'll not read the advice. It could be good to change a couple of the questions (one where the inequality remains the same, the other where it has changed) so they have the choose the correct inequality from a drop down as well as enter a numerical value.
In part g) of the advice, the wrong variable has been entered in the first line of the solution.

Thank you for the feedback, I think all the errors which you've highllighted should have been resolved by now.

PartsPart e has "x<..." in the expected answer. It should just be a number.
In part f, I think you've forgotten the coefficient of $a$.
AdviceI've corrected "on it's own" to "on its own".
Why were there sometimes brackets around the numbers? I've removed them.
Part d: minus signs have gone missing in the second line. You say you've highlighted something in red, but I can't see it because I'm colourblind. Find a way to refer to things in text.
Something's gone wrong in part e: the righthand $x$ term goes missing in the second line. And I wouldn't think of this as pulling out a factor of $x$ anyway: you're collecting like terms. The thrid line seems to be nonsense too.
Part f: I think the second line is supposed to have collected all the $x$ terms on the left, but the coefficient is wrong. And then I got a third line showing division by $155$. Why wouldn't you collect together first and just divide by $10$?
I dispute that it's easier to divide first in part $g$! I got an $h$ term and the advice says to divide by $2$ first. Maybe make sure that you're dividing by the gcd of all the coefficients, and the gcd is greater than 1.

Thank you for the feedback. I have now changed the questions into gaps to make them less hackable and reworded some of the feedback to be, hopefully, more eloquent and contain less typos.

Chris Graham 4 years, 1 month ago
You should pull $x<$ outside of the gap (or $x>$, as appropriate) and adjust the correct answers accordingly. The way the marking works is that the part's correct answer is evaluated at a number of test points, and in this case will return logical values: let's say it evaluates to true at all of the test points. If that's the case then any student answer that also evaluates to true at the test points will be marked as correct. Have a go yourself in part (a) with, say, x<100 or x=x.
Some of the wording in the advice needs to be carefully considered. For example, in part (a), are you really "subtracting the constant"? And there is a "constant" on both sides (thoug I appreciate that you give the value). I think I would be more direct and offer motivation for the step, with something like "to obtain x on its own on the left hand side, first add 8 to both sides"
There are a few typos in the advice, which is otherwise laid out nicely.

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.

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.
