Welcome to Module Three. In this module, we will explore the concept of the good laboratory teacher and provide some tips and strategies to help you improve your teaching and become a good laboratory teacher. We begin the module by considering what good laboratory teaching is, and we do this by putting it in a context. We'd like you to consider your best laboratory teacher when you were a student, and then, from there, what were the characteristics? What did this person do that made him or her the best laboratory teacher you've had encountered? From having done that, we will then get you to look at some literature to see. How the literature states? Are they important characteristics of good laboratory teaching? We then move to an activity, in which we'll help you better understand your class. And before you start your class, knowing something about the background of your class, the academic background, the interests of your class, are they majors for your discipline, or are they doing your laboratory class because they have to and they have a major in another area? And also, what do the students already know? What are the things that you need to stress that will be new, or what do they already know and you don't need to focus on to any great extent? Finally, we will provide you with some strategies and tips on preparing for class. And this is helping you prepare students for class by suggesting some activities you can get students to do, so that when they enter the classroom, they are already prepared to begin the experiment. And also, an activity which will help you as a teacher prepare for class, so that you can run the class more smoothly. And, to finish off this introduction, I'd like you just to finish with the learning outcomes for Module Three. So on completion of this module, you should be able to carry out the points listed here. I hope you enjoy the module. Goodbye.
