The learning curve
Whenever students ask me if I “curve” my course, my standard answer is “no, because I don’t believe in basing your grade on someone else’s performance.” But, that’s not the kind of curve I’m talking about today.
How many of you have lab reports or other written reports as part of your course? Most, if not all, I suspect. Communicate coherently about a subject is a way to demonstrate multi-dimensional understanding about it, since the student often must synthesize ideas to explain their subject fully. One important aspect of writing a report or a paper is understanding what the instructor wants in the way of format, content, etc. Although we clearly state our requirements in our respective syllabi, the students often don’t grasp our intent (assuming they read it in the first place) and the first (or first few) reports are usually pretty traumatic for both of us. This was my experience for several semesters until I decided to do something different and it has made a huge difference. In the chemistry course I teach, the students write reports on 9 labs through the course of the semester. During the first unit of the course, two reports are due. In the past, these first reports were usually terrible; indicating that many students had either not read or had willfully ignored my requirements. On average, it wasn’t until the 4th report that most students had gotten the message and had read and attempted to conform to the requirements. As you can imagine, this was a source of frustration for me – why weren’t they just doing what I asked?

Students behaving badly – online.
In my experience, I believe that the vast majority of online students are honest and honestly want to learn the material. Perhaps I’m being a Pollyanna, but even though I have caught students in lies and other dishonest behavior, that doesn’t change my general outlook.
Here are three of my personal “hall of famers” when it comes to bad behavior online:
1) Get the Facts! Student X wrote frantically, the day after a lab deadline, and told me that he had not been able to get online all week due to technical problems. Thus, the late lab report! Oh, if only he could have logged into the course before the deadline! Obviously, he didn’t realize that I had the ability to view (in Blackboard) when he had logged on, how long he had been logged on, and what parts of the course he accessed in that time period. Of course, he had logged into the course virtually every day during the previous week and hadn’t even accessed the lab dropbox. When I let him know that I could see his online activity during the previous week, he literally had nothing to say about it. However, he didn’t try to pull that particular stunt again.
2) Always keep your Department Leadership in the loop. My course policy on lab reports for the first unit of the course is fairly relaxed. Because students can sometimes have trouble getting the lab kits, I allow all the labs for the first unit to be turned in as late as the end-of-unit deadline. If they choose to turn in the first lab report prior to that, I will mark it and return it and it can be resubmitted for full points (this cuts down on the learning curve). One semester, student Y waited until the unit deadline to turn in all three of the Unit One lab reports. She didn’t do well on any of the three, having obviously not consulted the syllabus for the report requirements. She sent me a very polite email asking if she could please re-submit all three reports, since she was unaware of the course policies. I politely declined and pointed out that she could still get full credit on the remaining 6 lab reports. That’s when things got nasty. She began posting scathing comments about what a bad teacher I was to the discussion boards and sent me an email explaining how I was robbing her of her “A”. I immediately notified my Department Chair and sent him all of the previous email traffic so he could be ready for the gathering storm. Sure enough, her next step was to contact everyone at CCCOnline that she could find an email for, complaining that I was only interested in penalizing students, and not in helping them learn. Thankfully, she was quickly squelched and decided to drop the course.
3) Communicate in writing and keep all your emails. The last in our rogues’ gallery is the “Absent-minded Prevaricator.” I was calculating final grades a couple of days after the course was over, and noticed that student Z had not taken the final exam! I immediately contacted him via his external email and asked him if everything was OK. He replied that all was well, but that he had simply forgotten about the final. I let him know, since this was the case, that I would have to assign him a grade of “C”, which is what he had without the final exam. He said he understood and reiterated that it had been his fault. Then, he sent this email to the CCCOnline Registrar:
“Hello,
I dont know who I should be contacting about this. I had an emergency and was NOT able to take my chemistry final. I thought my teacher was going to extend the deadline for me, but he didnt read my emails. He thought I blew off the final because my grade was passing and very good at that. I ONLY needed to answer 5 questions right to get a "B" letter grade in this class.
He turned my grade in with a "C." This is unexceptable because I SHOULD have had a B and I actually would have gotten an A if I aced the final, which I had planned on doing. Please, I need help ASAP! Im sorry this email is so frantic but Im freaking out knowing that I got a C because I couldnt take my final exam.”
Well, it was comforting to know that he was planning to “ace the final”, but he was clearly lying about everything else. Since I had saved all the email traffic, we were able to quickly put this one to bed without further incident. I shudder to think how difficult this would have been if I had conversed with him over the telephone instead of email.
Even though you will occasionally run into some dastardly characters, and you should always keep your RADAR on for suspicious behavior, don’t forget that most students are being honest with you. Treat everyone with consideration, but be ready to deal with the situation if things turn ugly.

Why use Anonymous Discussions?

Redirecting discussions – keeping the topic fresh and engaging
Sorry I’m a bit slow on my posting lately. The past couple of weeks have been crazy busy with grading and business-travel and other things conspiring to use up all my free time. Anyway, here we go with part two of my three-part post on discussions.
When I first started teaching online, I kept getting “dinged” by Quality Assurance for not appropriately “redirecting” my discussions. “Redirecting”? I mean, I was participating and making comments and such, but it wasn’t immediately clear to me what that word meant. With some help from my mentor, it finally clicked for me.
Even if you choose the most exciting and engaging topic possible, as you’ve probably realized in your own classes, the discussion will usually run out of steam in a fairly short period of time; a few days or a week. Most of my discussion topics are set to run for at least two weeks, so this can be a problem. Another problem is that the earliest posters will usually get all the “juice” out of the subject and then everything kind of starts to lag. What do you do then? Trying to flog the original prompt doesn’t work very well (I know from experience), as it usually just generates insincere posts that mostly fill up space. Here are a few things that seem to work pretty well, and if you have any other tricks or techniques that you employ, please share them:
1) Stay involved in the discussion on a daily basis. I know we aren’t required to post daily, but at least read daily and maintain contact with the ebb and flow of ideas. This will offer you your best opportunity to see threads that can be tapped into for fresh directions or ideas, which is the next point.
2) Identify “juicy” posts and use them to push the discussion in a new direction. You know, the posts that students obviously thought about a little more than some of their peers, which offer some fresh ideas that you can work with? For example, in a discussion about uncertainty, precision and accuracy in my chemistry course, one student had this as part of one of her posts: “In working with the state crime lab, I was able to observe the impact of uncertainty in the drug/chemical department, in the fact that something must be tested several times to quantify amounts or even to determine the presence of a substance. If we were to test something inaccurately... it could mean a whole misrepresentation on an outcome of a case.”
State crime lab?! Cool! That led to a side discussion about forensic science that was pretty interesting.
In a discussion about energy use, one of my students asked a question about something he was thinking about purchasing. It was a fuel efficiency product for his car called “water4gas”, and purported to improve his fuel efficiency by a ridiculous amount. This was an opportunity to discuss the importance of really understanding the laws of thermodynamics and their implications in our daily lives and (hopefully) he was saved the expense of buying into this scam.
3) Ask them to think more deeply about the original topic, or about a related idea. After most of the important ideas related to the original discussion prompt have been tossed about, sometimes there’s no obvious direction to take the discussion. That may call for what is essentially a new discussion prompt. For example, one time my class was discussing what manufacturers might mean by advertising their products as “chemical free”. Within a few days, we had pretty much wrung this out by covering the ideas that all products are made up of chemicals and if something were truly “chemical free” it wouldn’t exist and probably the manufacturers were trying to portray their product as benign or harmless. OK, so where do we go from there? Well, I happened to see a news story about how some people were trying to get bis-phenol A (BPA that’s found in many plastic products) classified as a “toxic chemical”. So, I saw this as an opportunity to bring up the related question: “What do you think they mean by "toxic chemical"? What chemicals do you think of when you think about non-toxic chemicals? How are toxic and non-toxic chemicals differentiated?” This started a new line of comments and ideas that got the conversation going again.
As fun and interesting as discussions can be, however, you’ll always have students who won’t want to participate for various reasons. Next time, I’ll share some of my observations about the usefulness of anonymous discussions, which can be an avenue to help students get more out of your course.

Increasing sincere participation (by your students) in discussions
Of course, you’re going to sincerely participate in your online discussions, right? Actually, t hat’s my first bit of advice. To generate honest and open discussions with your students, you need to be honest and open yourself. You’ve got to really participate in the discussion with them, not just stand on the side and make sagacious comments now and then. It’s like the old adage about leadership: don’t ask them to do anything that you’re not willing to do yourself.
In addition, I have three suggestions to make that I have found increases student participation and helps in generating interesting and sometimes passionate discussions:
a. Keep the topics fresh and current. I’m not saying you shouldn’t re-use discussion topics – I do that myself. But keep tabs on them and spruce them up if they start to get a bit dusty. I often scour newspaper stories and science blog sites in search of topics that I can use in my courses. Speaking of newspapers, my doctoral advisor tells a story about a chemistry professor back in his native England. The professor had been teaching for many decades, and had a stack of extremely yellowed pages that he lectured from. One semester, a young man sat in the front row and quite openly read the London Times each day in class. After several days of this, the professor hurled an eraser at the student, knocking the paper from his hands. “Young man! I notice you are not taking any notes,” roared the old man. “That’s quite alright, Sir,” replied the student, “I have a copy of my father’s notes.”
b. Choose topics that your students can connect with. This is related to the first item, but is not identical. One of the most important factors in engaging students is providing them with authentic scenarios and problems to consider. Of course, because they want the points, they will feign interest in almost anything you provide them with. However, they will be much more engaged if you choose topics that are inherently of interest to them. In chemistry, for example, topics that involve explosions, energy use and conservatin, material transformations and the like tend to interest students very much. I’m sure you know topics within your subject that tend to appeal to students as well.
c. Invite them to share their opinions. If the subject is interesting and engaging (and often if it isn’t), students will have an opinion about it. Don’t waste the opportunity to get them to invest themselves personally in the topic. In addition to the dimensions of the discussion that relate to the subject being studied, ask them to share their opinion in some way. You can do this as part of your discussion prompt, or in the course of the discussion itself. Often, the sharing of personal opinions will open up an emotional channel in the discussion that enlivens it and draws more students into the stream. Of course, you have to watch carefully and make sure everyone remains civil, but that’s a much better alternative to trying to drag students into the conversation.
My next post will be on the subject of redirecting discussion – what to do when the conversation lags.

This is the first in a series of 4 posts regarding discussions in an online course. These are only my opinions, but I’ve developed them over the course of 12 semesters of online teaching. However, I welcome your thoughts about my posts – do you agree or disagree? What have your experiences been?
The topics I’ll post about are:
- The importance of discussions in online courses
- Increasing sincere participation (by your students) in discussions
- Redirecting discussions – keeping the topic fresh and engaging
- Why use anonymous discussions?
Connection
In the online environment, one of the most noticeable deficiencies is the sense of community that you can get in a traditional classroom. The lack of verbal and visible feedback from your students/classmates can lead to a sense of isolation. Discussions are one way to help alleviate this and help students connect with you and with each other. I’ve found that I learn more about my students from how they participate in discussions than from any other source of input, including email or other direct forms of communication. Of course, this requires an environment that encourages sincere and open participation by the students, which I’ll discuss in my next post.
Transference
The second important consideration, in my opinion, is that engaging students in discussions gives you an opportunity to assist your students in transferring what they are learning in the course to other contexts. Transference of knowledge from one context to another is one of the “holy grails” of education. It does very little good for a student to learn the principles of chemistry or the history of the United States if they lack the ability to transfer the principles and lessons into the context of their life and experiences. Imagine, for example, how terrible it would have been if we hadn’t learned from the long history of Western intervention in the Middle East and applied those lessons to our foreign policy decisions! Oh, wait, that’s a bad example. Anyway, engaging students in discussions about related topics has been shown, at least in some areas of learning, to improve transfer of knowledge to other contexts.

Can you pass the Turing Test?
I recently found this online course introductory post on the internet. I have blanked out the instructor and course names to maintain anonymity. Read this and imagine being a student in this class.
WELCOME STUDENTS: I AM XXXXXXXXXXXX, YOUR ONLINE PROFESSOR. SHOULD YOU WISH TO KNOW MORE ABOUT ME, JUST CLICK ON MY BIO WHICH IS LOCATED IN THE CLASS SYLALLUS. THANKS FOR TAKING XXXXXXXXXXXXX ONLINE WITH ME DURING THIS SEMESTER. I AM HAPPY THAT YOU ELECTED TO STUDY WITH ME. THE SCHEDULE IS OUTLINED IN SYLLABUS ANS SCHEDULE--SO--READ IT. PLEASE PURCHASE AND SECURE ALL OF YOUR COURSE MATERIAL AND LETS GET STARTED. PLEASE ADHERE TO ASSIGNMENT SCHEDULE DUE DATES--DO NOT FALL BEHIND...THERE WILL BE NO MAKE UP ASSIGNMENTS. PLEASE READ THROUGH THE CLASS SYLLABUS AND OTHER RELATED INFORMATIONAL MATERIAL AND EMAIL ME--AT ONCE--IF YOU HAVE PROBLEMS OR CONCERNS.
What do you think? Was this produced by a human or a computer? How would you feel about approaching this instructor with a question or issue?
The Turing Test
In the 1950’s, the great mathematician and cryptologist, Alan Turing, proposed an interesting thought experiment, which you’ve all probably heard of at one time or another. He proposed that for a machine (in those days, a “computer” was an actual human who worked with an adding machine) to give the illusion of human thought, it would have to pass the following test:
- The machine would be placed in a room separate from a human interrogator.
- The interrogator would ask questions of the machine (not knowing whether it was a machine or a human) and another human would pass the questions to the machine.
- The machine’s responses would be passed back to the interrogator.
- The appropriateness and validity of the responses would be used to judge whether or not the machine was “human” in its cognitive ability.
When you’re posting to a discussion, or answering email, keep in mind that your students are probably very intimidated by you – they don’t know you personally and they can’t judge your mood and tone by the sound of your voice or your body language. Since they are predisposed to be intimidated, you need to try and swing their impression over toward respectful friendliness. I use a lot of smileys and light humor in my messages to try to keep the mood light.
This is related to humor, but think carefully about how your word choices portray your personality to your class. I try to write colloquially, as I would talk with them if they were in a traditional classroom setting. The manner in which you word your introduction, discussion prompts, instructions, etc. will have a big impact on how your students perceive you. Above all, you should be consistent and sincere, because they will see through duplicity very quickly (just like kids always do :-).
We all will have students who develop issues and problems as they go through our courses. I have had students ask me for leniency because they:
- had a family member die
- are going through a divorce
- are extremely ill
- can’t get their lab kit delivered because they are in a foreign country
- are travelling out of the country on business
- were wounded in combat and airlifted out and couldn’t get to their lab kit (really!)

I am not the King of Boomeria
I’ve been teaching college chemistry, online and offline, since 1995 and sometimes I even think that I’ve got a few things figured out. Then, I discover someone that makes me feel like I have so much to learn that I almost want to give up. Like this morning, for instance, when I stumbled across “The Boom”, King of Boomeria. What an awesome teacher this guy is! After reading about him in Mental Floss magazine, I went to his website and was even more humbled by all the great material he has, as well as the obvious affection he displays for his students. I’m not, and will never be, the King of Boomeria.
