## Exercise Concepts

#### The structure of exercises

We use the following terminology with respect to exercises.

Exercise

An exercise is the container that contains instructions, questions and interactive elements. An exercise can be as simple as a single instruction and a single question (e.g. “Solve the equation $x^2+x=0$” with a single formule editor). An exercise can also be a complex piece of content, with multiple text blocks, questions (a, b, c), and many interactive elements.

An exercise can be randomised by using scripted variables in your texts and interactions. You can define these variables in a script.

Every exercise has a unique ID, which is used to refer to this exercise from your learning platform. You can see this ID in the URL of your browser or you can copy it to the clipboard using the copy icon on the top right of the page.

Audience

The audience defines for what kind of student the exercise is meant. For example, the audience can be set to “Key Stage 3, United Kingdom” or “Gymnasium, Deutschland”. AlgebraKiT uses this audience to automatically adjust the mathematical notation, worked solutions, and hints and error feedback.

Let’s consider solving the equation $a^2+a-20=0$ for $a$. The following worked solutions are automatically generated by AlgebraKiT based on the audience:

##### Grade 2 (Belgium) worked solution:

Note how the language of the explanations of the steps is different. Also, the notation for the final answer differs between the United Kingdom and Belgium.

You can select the audience of an exercise at the top of the edit-page:

Which audiences are available to the authors can be defined in the subject settings.

Question

A question is a subpart of an exercise. If an exercises contains multiple questions, then these will be labeled as a, b, c, etc. If an exercise has only one single question, then the label is not shown.

Icons to recognize questions

In case of a single question, the question is indicated with the edit icon in the tab at the left of the screen.

In case of multiple questions in an exercise, the questions are indicated with the letters a-z in alphabetical order. Default AlgebraKiT behavior is to also show these indicators to a student when making the exercise. They are used as subpart indicators of the exercise. These are customer specific settings, for more information contact your AlgebraKiT contact.

A question contains an instruction and one or more interactions.

Inserting an instruction

The question content is constructed as a vertical sequence of blocks. Each block can be a text block or an interaction block. It is also possible to insert some math interactions within a text sentence. These are called inline interactions. See Inserting an inline interaction in the question text editor for more information.

You can insert mathematical formulas using the $f(x)$ button in the editor menu.

Inserting an interaction

You can add an interaction to your question either inline (supported for some interaction types) or as a block element.

##### Note

An interaction can only be used once. In case the interaction is already used in your question, the interaction is greyed out in the selection menus.

Interaction

An interaction is a single interactive and scorable math element. AlgebraKiT supports several interaction types:

• Algebra
• Math Entry
• Multiple Choice
• Math Table
• Geometry
• Statistics
• Written Arithmetic
• Number Line
