planning and preparation
it is very important to prepare and plan for each lesson in conjuction with that you (the instructor) must keep also in mind that your preparation and planning is well researched for each student, every student is different and understand at his/her own pace. as an insturctor you should/must shift gears on a regular basis to reach each and every student in your class. its great that 90 percent of your class understand the topic at hand but what of the 10 percent that did not, you have failed to prepare and plan... 100 percent accountability. is your objective and goal.
If we as instructors show up to class unprepared it sets a poor example for our students and also does not give confidence to our students as to our expertise as an instructor. Students pick up on whether we are prepared for the class.
Planning and preparation is what separates a good educator from a poor educator. It is very important to know your audience before hand and also to have different plans in place just in case there's a need to deviate to suit the audience.
Yes it is very important to prepare and to plan for each lesson,and of course each student are diffenent and learn different,some students are visual and some are hands-on and some learn just by reading the materials, and some just learn by the lectures and the notes that are being taught.
