However, it may be shaped <strong>in</strong> various ways. In the discussed course, the discussion board<br />
consists <strong>of</strong> two parts.<br />
Th<strong>in</strong>k and Answer<br />
A week assignment <strong>in</strong>cludes four questions <strong>of</strong> the follow<strong>in</strong>g types:<br />
What is wrong about this statement<br />
Examples:<br />
• The United Nations Organization declared that the world’s six-billionth <strong>in</strong>habitant was<br />
born on October 12, 1999 <strong>in</strong> Bosnia.<br />
• An auto dealership opened on February 28 and sold 2 cars on that day. Dur<strong>in</strong>g the whole<br />
March, it sold 80 cars. The manager claims that they <strong>in</strong>creased their monthly sales 40<br />
times.<br />
Expla<strong>in</strong> <strong>in</strong> a paragraph or two.<br />
Examples:<br />
- We def<strong>in</strong>e probabilities for various normal distributions. However, we use one s<strong>in</strong>gle<br />
table (Standard Normal Distribution Table) for all <strong>of</strong> them. Expla<strong>in</strong> why that is possible.<br />
- Why cannot a confidence level be 100%<br />
True or false<br />
Examples:<br />
- Health <strong>in</strong>surance policy is designed <strong>in</strong> such a way that a healthy person has a negative<br />
expected value, and an ail<strong>in</strong>g one has a positive expected value.<br />
- A co<strong>in</strong> is flipped twice. P(two heads) + P(two tails) = 1.<br />
If we fail to reject the null hypothesis, we reject the alternative hypothesis.<br />
As can be seen from these examples, we tried to avoid questions that could be answered by<br />
copy<strong>in</strong>g a paragraph from the textbook. The students are required to give a justified answer to<br />
each question; not necessarily absolutely correct. Answer like “true” or “false” will not earn full<br />
credit.<br />
Open Forum<br />
This part is <strong>in</strong>tended for questions and answers concern<strong>in</strong>g mostly homework assignments. In a<br />
4-week course, it is especially important for the <strong>in</strong>structor to answer such questions promptly.<br />
Besides, if one student has stumbled over a problem, so could others. Therefore, post<strong>in</strong>g the<br />
answer <strong>in</strong> this forum benefits the whole class.<br />
The <strong>in</strong>structor’s answer should conta<strong>in</strong> not the full solution <strong>of</strong> the problem, like <strong>in</strong> a<br />
solution guide, but a carefully measured h<strong>in</strong>t that gives the students the general idea and<br />
direction, leav<strong>in</strong>g the rest <strong>of</strong> the work to them. To do it without delay, it is very helpful to have a<br />
bank <strong>of</strong> such h<strong>in</strong>ts. Certa<strong>in</strong>ly, this bank can be only created gradually, as the questions are<br />
com<strong>in</strong>g <strong>in</strong>, but it will serve as long as the current edition <strong>of</strong> the textbook is <strong>in</strong> use. Unfortunately,<br />
the bank must be created from scratch as soon as a new edition was adopted.<br />
We always encourage students to answer their classmates’ questions. This is one <strong>of</strong> the<br />
most valuable activities <strong>in</strong> an onl<strong>in</strong>e course. Those who do it receive some extra credit. Open<br />
Forum <strong>in</strong> onl<strong>in</strong>e mathematics courses takes on some <strong>of</strong> the functions <strong>of</strong> a chat room. The pace <strong>of</strong><br />
