I think long division of numbers is something a lot of students probably students struggle with, so i think it's still worth explaining how to do it.

I could maybe split the advice into two columns, one column showing the steps of dividing the polynomial with remainders and the other column showing the equivalent steps in long division form like you mentioned in the meeting on Tuesday but i'm not really sure how to do that.

Saved a checkpoint:

Can we assume that the students have already seen long division of numbers?

I've rewritten the statement a bit. 

"We then repeat these same steps with the new polynomial until we are only left with an integer. " isn't strictly true - the remainder is a polynomial of lower degree than the divisor.

I reckon the statement text is better off in the advice.

The advice is quite lengthy, but I don't know if it's possible to do any better.

  • I think the advice for the division should be reformulated, and focused more on being the algebraic long division with some narration. I think there should be a long division illustration of each bit of narration after it is said, and then you end up with the full one at the end. I also think the narration could be a little clearer in places. You have mentioned that you are dividing the first term of the polynomial by x, but haven't explicitly stated that that is because the first term of the divisor is x. Someone might be misled to think that dividing by x is always the first step to do, which it is not. 
  • The question is quite short, would you maybe think about adding a second part where the divisor is a quadratic or something to make it a little harder?
  • Would you want to include a statement? You could state what a polynomial is, or give a definition of algebraic long division or something.
  • Good grammar, I can't pick you up on anything to do with that, well done haha!!

Created this.

There is only one version of this question.

Give any introductory information the student needs.

No variables have been defined in this question.

(a number)

Numbers between and (inclusive) with step size
A random number between and (inclusive) with step size

(text string)

(numbers)

(text strings)

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.

Base marking algorithm

                                        
Custom marking algorithm


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.
