The often used saying "that you only get one chance to make a good first impression" is really true when it comes to starting a new class. As you prepare your syllabus and content for the first class stop for a moment and reflect on the impression you will be making as you start the class. You can ask yourself some questions as a check to see if you are making the positive first impression you want to make with your students.
These questions are: Am I dressed appropriately and professionally? Is my classroom/lab clean and organized? Do I have all of the necessary supplies and equipment available and laid out? Does the learning setting look inviting to students? Am I ready to start the class on time?
With these questions answered, a smile on your face and a confident attitude you are going to make the positive first impression that you want.
