What’s new in the world of chemical education in 2013? In this edition of the CE Roundup, I’ll engage in a bit of shameless self-promotion, and we’ll look at articles that shed new light on the costs of publishing, innovations in laboratory instruction, student evaluations, and more.
Let’s get the shameless self-promotion out of the way first. Two weeks ago, the Introductory Organic Chemistry MOOC (massive open online course) kicked off on Coursera. The materials for this course were prepared by myself and my colleagues at UIUC for use with our organic chemistry 1 course for non-majors. I’m leading the Intermediate Organic Chemistry (organic chemistry 2) effort, and although that class hasn’t started yet, I’ve been knee deep in the MOOC world for a while now. I’ve got a whole series of blog posts planned on the MOOC experience, so stay tuned!
What is it about the winter months and great literature articles? Perhaps the cold bores people into writing. Who knows? Either way, the literature’s been very interesting in early 2013.
First, teacher reflection and cognition in the classroom. Reflective teachers generally see better student evaluations than unreflective ones. No surprise there: drivers who actually watch the road are better than those who don’t! But how much reflection is enough? A recent study in Brit. J. Educ. Technol. sheds some light on the question. The authors found that formative (weekly) student evaluations increased teachers’ reflective practice, and that increased levels of the latter lead to higher student evaluations over a multi-year period. Some would say that formative student evaluations could promote a “consumer culture” in education, however. There’s an interesting debate brewing there. In a study focused on science teachers, a team of researchers writing in to J. Res. Sci. Teach. found that teachers’ “noticing patterns”—patterns in their attention during class—indicate the ways in which they frame the classroom. Particular noticing patterns point to particular frames. Furthermore, the authors add, a given teacher is capable of multiple frames, depending on the classroom’s context. Their theoretical ideas are elegantly demonstrated in a video-based study of a high school biology teacher in action.
Laboratory instruction came under the qualitative microscope this month in a report by Bretz, Towns, and co-workers. They studied how instructors of different laboratories prioritize cognitive (thinking), affective (feeling), and psychomotor (doing) learning goals. This work draws attention to a potentially concerning decline in affective learning goals as students move from general chemistry to organic chemistry. In other laboratory news, a simple apparatus for flash chromatography gives results comparable to traditional columns and “obviates the need for students to handle silica gel”, and instructors at South Dakota State University have reported on instructional design for a laboratory sequence aimed at producing student researchers.
The editor-in-chief of J. Chem. Educ. has written an editorial describing the costs of publishing, and rationalizing some recent price increases. It’s worth a look, particularly if you’re interested in the broader forces acting on academic journals these days. Also interesting are the editorials citations, which include familiar language from the journal’s past editors.
