Brother you really nailed it.

As a Teacher it's always important to kn the students around you, to help choose a learning technique that'll ease learning process.

We know many students are not of same learning page, some are fast learner depending on their background and what techniques they're exposed to. While some might be dull because they're not familiar with the technique which not necessarily means they're not good with others techniques or methods.

so Analyzing the students strengths and weaknesses helps to moderate the best method.
Now pointing to your practical observation on behavioral character of your friend, I'll say that was a very nice one and emotions is definitely considered while learning because some students might be engulfed to it and sometimes hindered their progress or contributions.

thank you I've learned a lot amd good luck 🤞
