This instructional strategy is based on bottom-up approach.
Explanation:
In this case, before teaching an experiment, the students are being trained about the components used in those experiments. This method of teaching will help students to learn the basic concepts and mechanisms of that experiment easily.
As they are learning about the components used in those experiments first, they can easily understand where is the problem occurring in case of any error. So, this type of approach of learning is termed as a bottom-up approach. Because the students are learning from the starting that is bottom and then they are making it as a whole experiment which is the up mechanism.
