Required parts

Multipart questions with required parts

Algebrakit allows students to be flexible and choose their own solution approach. But sometimes, you want to force students to write a specific step. For example,

you want students to follow a specific approach
or you want students to write intermediate steps.

Live example: Examples of multipart problems.

Example 1: Enforce a specific approach

Consider the first example.

Example problem 1

Expand the brackets, then calculate the value of p.

$6\left(p-1\right)=12p+18$

There are several ways to solve this equation, but you want students to follow the approach of expanding the brackets. To do so, split the task into two parts, one to expand the brackets and one to solve the expanded part for $p$ .

For the part to expand the brackets, use the dropdown menu to make it required.

The dropdown Figure: make a part required.

A star symbol indicates that this part is now required.

The star Figure: a star indicates the task is required.

If students attempt to solve the exercise without expanding the brackets, Algebrakit will notify them that they have missed a step.

The hint Figure: the student gets feedback when skipping a required step.

Example 2: Write all intermediate steps

Consider the following STEM exercise.

Example problem 4

A car is travelling a distance $d=84\text{ km}$ with a speed $v=20\text{ m/s}$ . How many minutes does it take the car to travel this distance?

We want to deduct points if the student does not write the standard formula for speed and time, $d=v\times t$ . Create a separate part called "formula" and make that part required. We also make that part a precondition of the solution.

The intermediate task Figure: The intermediate task of writing the formula.

If students do not write the formula, Algebrakit will not evaluate the expression and instead give feedback. Algebrakit will not award marks for the input, even if this input is correct.

The student skipped a step Figure: A student receives feedback that they skipped a step.

Once a student enters the formula, Algebrakit grades all steps and awards the marks.

Figure: A student enters the formula afterward.

With assessment mode enabled, students will not receive immediate feedback. Students will receive the marks for the correct steps, but Algebrakit will not award the marks for the skipped step.
