To be sure you have a working link you should copy the address directly from the address bar in your browser and then paste it into your message. After posting your message check your link to make sure it is functional. Be sure your posting is directly related to the topic of the week. If you are using a site dealing with a variety of physics information, be certain to reference the particular page which applies to the week's topic. Your discussion of the web site should convey the content of the site so that your classmates know what they will find there and how it will help them understand the week's material.
Every student has the responsibility to participate in on-line discussion.
This is vital if the course is to reach its full potential. Each time you log in be sure to check the folders for new postings. Respond to postings of the igniter and other classmates. Use Reply to respond, rather than starting a new message. If you find something interesting or puzzling, if you want to ask a question, start a new thread .
