The learning in an online course is greatly enhanced through the exchange of student ideas on the bulletin board. We learn from each other. As President Woodrow Wilson once said, "I not only use all the brains I have, but all I can borrow." Thus the bulletin board (discussion) is an integral part of Bio 100 Online. As such, it counts as part of your grade.
Writing to a bulletin board is different from writing a term paper or an essay question on an exam. As you post messages to the bulletin board, keep the following goals in mind:
1. SUBSTANTIAL. Messages should relate to the subject matter. They should provide information, opinions or questions about biology concepts. Relating the subject matter to personal experience is acceptable as long as the focus remains academic in nature.
2. CONCISE. Messages that are several screens long generally do not receive replies. Effective messages get to the point, are clearly stated, and are limited to one screen.
3. INTERACTIVE. The bulletin board is working best when interaction occurs. A good message explores, explains, or expands on a concept. If classmates reply or object, the message has served its purpose. A focused message that induces replies from fellow students moves the discussion forward and enhances learning.
4. CONTEXT. A good message appears in the context of other similar messages. Reading the bulletin board regularly provides the opportunity to enter the discussion on a regular basis. Otherwise your comments apppear late and out of context.
5. LOGICAL. Educated persons value arguments that are logical. If your message is not a question, it should contain a logical argument. Conclusions should be clearly stated and supported by premises, reasons, evidence, or grounds for belief.
In addition to the above qualities, it is assumed that bulletin board messages are grammatically correct. Ten percent of your course grade is determined by the quality and quantity of your bulletin board messages.
You are expected to post at least one message on each bulletin board. Your posting should be completed by the date shown on the course calendar. This will provide enough time for reading and reflection on the postings before the weekly quiz.
If you are asked to describe an experiment you conducted, include enough details that the reader could duplicate your experiment exactly. Clearly articulate the sequence of activities you performed. Describe your specific results.
You should also post at least one message each week that responds to a posting of a classmate - replying, expanding, etc. on his or her comments by the date indicated on the course calendar.
Quality postings are more than "Good job!" or "I agree with you!" comments. If you agree with a classmate, explain the reasons for this. If you disagree with a classmate (or got results that differ from what he or she posted), describe the situation in enough detail that the reader can understand why you have a particular point of view.
Examples or analogies that expand on a concept are excellent topics for postings. Information that you have learned about the topic (e.g. from something else you have studied, your textbook, the internet, something you've read) lead us toward our goal of being a community of learners.
TWO EXAMPLES OF GOOD BULLETIN BOARD POSTINGS:
1. I think that it's interesting that I did the same solutions you did but came out with different results. When I was doing the experiment, I used water from my refrigerator door and briefly wondered if all the chemicals (fluoride, etc.) that the city puts in the water would affect my outcome. After reading your results, it makes me wonder even more if I were to do this experiment using distilled (or a different type of water) if my experiment would come out differently. - A. S.
2. My experiment was conducted using
cigarettes. I have to start off by saying that if anyone else is a smoker you
might have heard the comment that it takes about 7 minutes to smoke a cigarette.
That in my case is untrue. I smoked a cigarette every 15 minutes (not a good
idea). The first on took 4 minutes and 8 seconds to smoke. After smoking my
heart rate was 81 bpm. I figured it would be higher than that because nicotine
is a stimulant. I took my pulse every minute there after to see how long it
would take to return to normal which is 83 bpm. After 1 minute it was 93 bpm,
another minute it was 77 bpm, and another minute it was 83 bpm. This first on
took about 3 minutes to return to normal.
The second cigarette was smoked 15 minutes
later. It took 2minutes and 50 seconds to smoke. When I was finished my pulse
rate was 89 bpm. I didn't notice much of an effect on my heart rate but I was
feeling sick. After one minute it was 75 bpm, another minute it was 77 bpm, and
another minute it was at 74 bpm. It took about 6 minutes before I saw it at 83
bpm.
The last one was smoked 15 minutes later than the last one. I took 2
minutes and 57 seconds to smoke and after it was done my heart rate was 81 bpm.
One minute passed with a heart rate of 74 bpm, one minute later it was at 79
bpm, and another minute later it was 76 bpm. It took about 4 minutes to return.
Each time that I did this the
results were never the same. I probably could have let more time elapse between
smoking so that my heart rate was at a resting state for longer. I think it also
depends on what you are doing while you are smoking that may increase your heart
rate. I was sitting. Sometimes I walk around. I can say that it took about 4
hours for the nausea and the headache to go away! - M. G.
As in a traditional class, student discussion on the bulletin board is conducted in a respectful, courteous manner. Postings which are inappropriate will be deleted by the instructor and the student warned. If subsequent violations occur, the student may be withdrawn from the course.
