“Teachers shouldn’t expect to make a difference in the life of every student. They don’t and won’t. But making a difference in one life is a powerful motivator. We never forget those students who tell we have, and we are further motivated by those teachers who once made a big difference in our lives.”

The 2009 Sloan Survey of Online Learning reveals that online enrollments rose by nearly 17 percent from the previous year. The survey of more than 2,500 colleges and universities nationwide finds approximately 4.6 million students were enrolled in at least one online course in fall 2008, the most recent term for which figures are available.

I was looking something up and happened on this brief identification of the defining characteristics for problem-based learning (PBL). Not only does it offer a great review, but it reminds us why PBL is such a powerful pedagogical strategy.

There are two common assumptions about teaching online that can sink even the most well-meaning neophyte. One is that “teaching is teaching” regardless of whether it’s face-to-face or online and there’s no reason to deviate from the proven principles that work so well in the traditional classroom. The second assumption is that teaching online is all about the technology, and if you design your course properly, it pretty much runs itself.

Regardless of the size of course enrollments, the key to a successful teaching and learning experience for both the learner and instructor is communication. Clearly defining and communicating the expectations will address the uncertainly of what role and responsibility is required of each participant.

There’s something about the unannounced quiz that’s awfully punitive, probably reinforced by the way many instructors use them. Pop quizzes occur when there aren’t many students in class or when the class doesn’t appear to be well-prepared. They do get more students coming to class having done the reading but students are preparing because there may be a quiz—that’s different from daily preparation motivated by the understanding that regular interaction with the material helps learning.

Course management software programs make it especially easy for instructors to provide students with a set of complete lecture notes. It seems that more instructors are doing this, as witnessed in the regularity with which students ask that the instructor’s notes be posted. But is giving students a complete set of notes a good idea?

My students are always asking for opportunities to earn bonus points. I offer a variety of assignments during the semester, but they still want bonus points, which they seem to think are easier to obtain than the required points. Generally, I’m opposed to bonus options because I feel that if students are struggling with the current assignments, they do not need an “extra” assignment for extra credit. In addition, the word “bonus” seems to suggest something for nothing. I want my students to realize that grades are earned, not given. However, I recently tried a bonus activity that benefited my students and also met my expectations for a substantive learning experience.

When I took an ungraduate chemistry course a few years back, I loved lab, but I have to admit writing up the lab reports seemed like so much busy work. Each report had specified sections, and the lab manual offered advice on what to put in the sections, depending on the experiment. I remember trying to get them done in a hurry and thinking that I wasn’t learning much by doing them. They seemed more like something the instructor could use to make sure you (and your partners) had actually done the lab.
