Lab Exercises

To help learn the human body, I have assigned a number of laboratory exercises found in your lab manual. These are easy exercises that help you learn the material and get an easy ten points each week. I have found that students who attend labs and who take time to perform the lab exercises do very well in the course. I will let you know which sections of the exercise need be done. See the above schedule for a list of exercises. Exercises are due one week after the assigned date. Work turned in on time can receive up to ten points. See criteria below. Worked turned in after the due date can receive up to half credit if received within one week. Work turned in later than one week late will not receive any points. Lab exercises are worth a 100 points of your grade. As you can see, there are twelve weeks of worth of assignments. This means that you can earn up to twenty extra credit points if you turn in all work. Points will be taken off for unexcused absences.

WRITTEN ASSIGNMENTS

You will be required to turn in some written homework each week. Keep in mind that sometimes there may be no correct answer a question. In some cases you may even give an incorrect answer and receive full credit. What I am looking for is for you to support your answer intelligently. Since one of MATC’s CORE ABILITIES is to communicate effectively, I ask that you proofread your assignment correcting spelling and grammatical errors.  Criteria are listed below followed by an example of what two students answered for a critical thinking question. Written home must be type written and can be turned in via email or by bringing it to class. Do not infer that I know what you are trying to say. Effective communication means that you fully explain your answer.

Criteria/ lecture assignments
Meaning: insight/depth of answer        0-4 points
Development: sufficient support           0-2 points
Organization: well developed                0-2 points
Grammar/Language                                0-2 points

Examples of a question and answer:
QUESTION: What events, discoveries, or inventions were probably the most significant in the development of microbiology and why? (10 points)

Example 1 Answer

The invention of the microscope was probably the most important discovery. It allowed the observation of  the tiniest of organisms, blood, human tissue, insects, minerals and plants. Without the microscope many people could have died not knowing which parasite or bacteria was infecting there body.

The discovery of spores and sterilization-the word sterile meaning completely  free of all life forms including spores and viruses. The capacity to sterlize objects and materials is an absolutely essential part of microbiology, medicine, dentistry, and industry.

The developement of Aseptic techniques aimed at reducing microbes in a medical setting and preventing wound infections. It mainly involved disinfecting the hands and the air with strong antiseptic chemicals, such as phenol, prior to surgery.

All three of these help to keep the microorganisms under control, to help people live longer and healthier lives, to have safer more effective surgerys, with more efficent health care.

Critique of answer 1

The length is appropriate. There are a few spelling errors (highlighted) and grammar that should have been cleaned up and the last sentence is a fragment. However the student’s arguments were good and she received 9 points and would have received 10 points had the spelling errors not occurred.

Example 2 Answer

Microscope awareness of widespread distribution of miroorganisms wouldn't possible without microscopes.  The establishment of the scientific method is the background of scientific reasoning.  This is the guideline that scientists follow.

Critique of answer 2

This student provided a couple of examples, but really did not back up his argument. Grammar is poor. He would have received partial credit (5 points).
