General Instructions:  Ever want “a voice and choice” in your learning?  Here’s your chance!  Decide how many points you will earn and what assignments/labs/evaluations that you will do.  When you are ready for the instructor put your table tent up at your desk and move on to your next task while you wait 

Complete one “layer” before going on to another layer.  Each assignment has a point value based on the amount of time and effort necessary to complete that task.  Be prepared to discuss and answer questions about each of your assignments.  You will be awarded points by your teacher based upon your ability to discuss and answer questions about your work.  When appropriate, you may work with a partner or partners, but you must be able to answer the teacher’s questions without any assistance.

CONTENT LAYER must be completed before beginning the LAB LAYER.  Also you must pass the exit quiz over the CONTENT LAYER with at least an 80 %. 

You must take the C layer quiz by Monday May 21st.

 

The entire unit must be completed by Friday May 25th. 

This will be the day of the test and all Application Layer Assignments will be due. 

A maximum of 10 extra credit points may be done. 

5 Points will be deducted per day for not using class time and being off task. 

Grading Scale  This is a combination of Content Layer points and Lab Layer points

135-121 pts  A

120-108pts  B

107-94 pts C
