Utilize different teachiong styles in hopes to cover the everyones learning style.

Try to incorperate mini-lectures 10-15mins in legnth. 

When providing demonstrations, practice prior to doing it live in class and make sure the demos have no more than 7 steps to ensure students will remember all the steps.

Its important for the students sccuess to allow them to feel at ease. 

At the beginning of the course instructions should open up with an introduction about themself.

THe instructor should then allow students to provide some information about themselves.

This will allow everyone to get to know each other a little better. 

As the course goes on instructors should greet students at the door of class/lab with a friendly smile and "hello".

In short... Be prepared!

Arrive to class early. Make sure everything you or your students need is available before it is needed.

Keep a small notebook with you to make note of any needs or to follow up on anything student requests.

Be prepared and be excited about the topic! Be professional. Be a model.
