The trainees are often overwhelmed in their information research. On the one hand, this concerns the seemingly infinite amount of information, especially from the Internet. On the other hand, the information is often completely unstructured.
Here the trainer should ask specific guiding questions.

Take a look at some of these leading questions here.

Good guiding questions

Which artificial masonry stones do you choose for the garden wall? Why?

What concrete mortar do you use for the garden wall? Why?

How are you gonna join the garden wall? Joint smoothing or subsequent jointing? Give reasons for your decision.

What tools do you take to the construction site?

Unsuitable guiding question

Name three different artificial bricks.

What types of mortar do you know?

Name different types of jointing.

Which masonry tools are available?

Note: the leading questions do not serve to query knowledge, Photos on https://visualhunt.com/

but to help the trainees to research the necessary information at the right time.
