Spring is here… too early

This morning, the novelist, Rui Umezawa, who is a neighbour and who kindly reads my blogs, asked me why I have been so inactive on the blogging front. "Too busy", I yelled across the garden fences. This term I have been teaching BIOLOGY 2010, the Plants course, which I taught from 1991-97, before powerpoint and course websites. So, while all of those life cycles are forever burned into my brain, chalk and talk, as we call that style of lecturing, is, in science, pretty much gone the way of the dodo. I have had to create Keynote and Powerpoint lectures and to learn "moodle" which is the most comprehensive electronic classroom software that I have ever seen. This open source software has replaced the way that I previously accessed my course websites - namely through the very nice, and now retired Biology Department Lecturer who functioned as our webmaster.

Moodle has allowed me to teach this course as I always wanted to: skipping from chapter 1 directly to chapter 32, and then to 21, to chapters 2-8, to 11-12 and then 18, 17, 16, 15, 14, 13 in Raven et al's Plant Biology 7th Ed.  CRAZY, right? But in fact, moving through the material in this sequence always made more sense to me than the linear way that I was forced to teach in earlier versions of the course text book: i.e. start at chapter number one and proceed forward in a one-way sequence. The internet and moodle has provided me with the tools to lay out a completely different roadmap than that provided by the book's author's and index, and, in 2010, the students can follow my map and route through the text book. If I had tried to do this in the 1990s, supported by paper course handouts and chalk and talk lectures, there would, most likely, have been a revolution in the lecturehall. Students who missed classes would have been griping about the jumping around, and any deviations from the lecture schedule, when I found that I was not delivering planned lectures on the expected date. With moodle, I  constantly update the students about where we got to, and with podcasted lectures, they have more flexibility than ever before, to miss a class and still catch up.

I LOVE IT - but it's been a heck of a lot of work at the back end. Still, there's nothing like jumping into a new technology with two feet, and sinking or swimming. The York University support staff have been amazing and I have taken several mini-courses. And, the time involved, has meant no time for blogging here. But, I have sought to imbue the course with a large measure of sustainability thinking. This is easy to do in a course that is essentially about biodiversity, why plants are important to humans, and about evolution. Our lectures on the Carboniferous and the tree ferns and progymnosperms (ancestors of seed plants) that fixed enormous amounts of carbon, and which subsequently turned into fossil fuels, relate directly to human-produced greenhouse gas emissions arising from the burning of these fossil fuels. I found an amazing old You Tube video about fossils, from the 1950s or 1960s by Royal Dutch Shell (that's Shell Oil to you and me), that the students have watched.

Everything is connected. Teaching about flowering plants and pointing out to my students that trees are already flowering , has reminded me, every day since early March, that climate change is happening NOW. I told my husband yesterday that one is supposed to prune roses when the forsythia blooms, and today, I have seen forsythia flowers. My gardening journals from the 1990s tells me that in 1994, the forsythia was only just flowering on April 27. In the early 2000s, I was noting that the forsythia blooming in mid-April was just "too early" - and in 2010, it's been flowering since the 2nd or 3rd of April. Climate warming is here, and in fact, in the USA, the Gardening Zones were  adjusted in 2006 by the Arbor Day Foundation to reflect this.
