200 Multiple Choice Questions (Algebra) - Part 2

We'd like to propose more work on creating algebra exercises, similar to the exercises that you've successfully completed for us.

This time the exercise items have to be created on our online platform for educators and students. We've transferred the multiple-choice items you have created earlier onto the platform and they're now available online.

The second project consists of 200 questions. The budget for the project is $200 and the time duration is 3 weeks. The source textbook is again "Elementary Algebra" by Ellis & Burzynski (available at [url removed, login to view]).

We will pay $100 after completion of 100 questions, and the balance $100 after completion of the project.

We need a new set of 100 multiple choice questions that have algebraic expressions as answers and distractors.

In addition we need a new set of 100 "Randomized questions" where numerical values will be automatically generated so that the students will see questions with different numbers, and will have to compute the answer and enter it.


Q. no 29 in your submitted items from Ch9 "Roots, radicals and square root equations" is:

At a certain electronics company, the daily output $Q$ is related to the number of people $A$ on the assembly line by $Q = 400 + 10\\sqrt{A + 125}$. Determine the number of people needed on the assembly line if the daily output is to be 520.

This can be posed in our platform as a randomized question by replacing the constant 520 by a variable for e.g. ${q}. Then a range of values for the variable e.g. 510 to 530 is specified. The answer formula is specified for e.g. (q-400)^2/100 - 125. Students will be presented with randomly sampled values for q in the range 510 ... 530.

So questions that require a numerical answer to be computed by the student should be posed as numeric randomised item types, while questions that have algebraic expressions as answers should be posed as multiple choice item types.

If you accept the project, we will provide you with a teacher account. You can first examine some of the exercise items that have already been created, including those based on the items that you submitted earlier to us.

Then create a couple of multiple choice exercise items and randomized questions to familiarize yourself with the GUI. After that you'll be ready to create items for the project. The built-in Math editor uses a subset of Latex.

We'll provide you with a detailed step-by-step guide as well.

Please let us know if you are willing to take up this project, or if you need any further information.
