How would you help a student stay motivated?

I'd talk about how the problem in front of them relates to their life goals. It usually does. Even if it doesn't, I'd still encourage them to follow their calling.

If a student has difficulty learning a skill or concept, what would you do?

Take time to figure out what it is they aren't getting and explain it carefully. Probably use a few videos/diagrams.

What strategies have you found to be most successful when you start to work with a student?

Understanding your students' motivations is the most important step for any teacher. When I know why they want to or don't want to learn something, I can work with them to get where they need to go.

How would you help a student get excited/engaged with a subject that they are struggling in?

Show a cool example of the theory in practice (like burning solid ice).

What techniques would you use to be sure that a student understands the material?

I usually explain the method of solving a problem in general terms. If they are solving the problems correctly with my explanation, it's usually because they have a solid grasp on the theory.

How do you build a student's confidence in a subject?

I guide my students to the right answer, but I let them take the last few steps. It's much more gratifying to finish the problem yourself than to get handed an answer after a long explanation.

How do you evaluate a student's needs?

I ask them what they want to accomplish; in class, in life, in general.

What types of materials do you typically use during a tutoring session?

I'll draw/work out problems with a pencil or dry erase. I'll also present short videos when appropriate, such as Virtual Cell for biology explanations.

What is your teaching philosophy?

If they don't know it, explain it carefully.
