Lovely question!

I would remove the old bits. The same advice and more is now shown in the tables.

Thank you Vicky. I've added the tables now. I'm not sure whether I should keep the original advice for parts vii) and viii) or whether I should replace them completely. I've kept them there for now.

Vicky Hall 3 years, 5 months ago

I really like the set up of this question and I think it will make the student think quite hard about properties of numbers. I've reworded some of the advice to make it clearer. I also think that, for consistency, parts vii) and viii) in the advice should have a table of values for $-3 \leq x\leq3$. It makes your conclusion look a bit stronger if you have checked a range of positive and negative numbers and can show a trend.

This variable is an HTML node. HTML nodes can not be relied upon to work correctly when resuming a session - for example, attached event callbacks will be lost, and mathematical notation will likely also break.

If this causes problems, try to create HTML nodes where you use them in content areas, instead of storing them in variables.

Describe what this variable represents, and list any assumptions made about its value.

No parts have been defined in this question.

Select a part to edit.

Ask the student a question, and give any hints about how they should answer this part.

The correct answer is an equation. Use the accuracy tab to generate variable values satisfying this equation so it can be marked accurately.


Advanced settings


Checking accuracy

Define the range of points over which the student's answer will be compared with the correct answer, and the method used to compare them.

Variable value generators

Give expressions which produce values for each of the variables in the expected answer. Leave blank to pick a random value from the range defined above, following the inferred type of the variable.

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:

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.

Run this script the built-in script.

This script runs after the built-in script.

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.
