Hi Dorothy,
The goals and objectives for the course comes out of the competencies that the students need to have at the end of the course. Sort of a form of reverse engineering. Then break the objectives down into learning activities that will give the students the knowledge and learning opportunities that will help them acquire the needed competencies for that unit. Go into each class with a clear idea of what you want to accomplish that day and what your students will need to do to learn effectively and efficiently. So if a group discussion, guest speaker, lecture, demonstration or panel presentation will do that then that is what you do. Check for comprehension on a regular basis so you can measure your effectiveness.
If you have any specific questions let me know and I will be glad to help you in anyway I can.
