How “professional baggage” may be a key barrier in changing how we teach

A little while ago, a colleague in the UK sent me this article (via twitter, of course!): “Barriers to Faculty Pedagogical Change: Lack of Training, Time, Incentives, and…Tensions with Professional Identity?” by Brownell and Tanner. He knew I’d be interested - I’m always experimenting with my own teaching, but I’m also aware that I’m in the minority.

The article starts by making an excellent argument that we KNOW how to improve teaching at Universities, but little change takes place regardless. Brownell and Tanner make the argument that barriers to Professors wanting to improve their teaching are often related to lack of training, lack of time, or lack of incentives. This fits with my impression of Academia, especially at a research-intensive University such as McGill. When I arrived over 10 years ago, I had little training as a teacher (other than a couple of short workshops), I had little time to devote to teaching improvement (I was barely ever one lecture ahead of the students!), and I was mostly encouraged to concentrate on developing my research program. There were not a lot of incentives to foster, improve, or change my teaching approach. I don’t blame anyone for this, nor am I bitter about my experience. It was the norm, and perhaps still is for most tenure-track Professors at a University with a significant research focus. So, as I began reading Bronwell and Tanner’s paper, it resonated, and I agreed that training, time and incentives were key barriers to changing pedagogy.

Brownell and Tanner, however, ask a clever question: if we imagined those three barriers gone, would we see immediate improvements in teaching? Would Professors suddenly value pedagogy and teaching improvement differently, and find ways to change their approach to the classroom? Perhaps not - and this is where the article gets interesting.

The article focuses on “Professional Identity” as being a key barrier to improved teaching, but one that is often understudied and underappreciated. They define professional identity to be the following: “how they [scientists] view themselves and their work in the context of their disciplines and how they accrue status among their professional colleagues as academic scientists”. In other words, it’s the process related to the way that we become an expert in our discipline - the culture, the context, and the training we receive. It’s the intangible as well as the tangible things that become our professional baggage. Brownell and Tanner argue that, for many scientists, we learn early in our careers to value research over teaching, and there is (for the most part) a greater emphasis placed on developing our research profile. There is often time and incentives to do some teaching (e.g., Teaching Assistantships are paid, and have hours associated with them), and there is training available (McGill’s SKILLSETS programs are a fine example). Regardless, the culture of science is mostly related to research and we are ultimately judged on research production rather than teaching. My personal experience supports this idea, and I have found myself often discussing this with my graduate students - I sometimes have advised them to avoid extra teaching responsibilities if it is going to slow down their research productivity.

Brownell and Tanner go into a lot of detail about the tensions between the development of professional identities and participating in pedagogical change. They make a very strong case: among several lines of arguments, they illustrate that scientists are often afraid to change their teaching approach for fear that it may be frowned upon by their peers, or that their teaching evaluations might suffer (and, in in the short term, this may be true). They also argue that the scientific culture, at large, places a lower value on teaching than on research, and it’s hard to overcome this.

The article finishes with some ideas for change: “we need to find ways to challenge the assumption that a scientist’s professional identity should be primarily research-focused and consider ways in which teaching could become more integrated into the fabric of the discipline“. The authors suggest 1) graduate student and post-doctoral training goals need to be broadened, 2) scientific journals should include/value papers and research related to education, 3) scientific conferences should better integrate education into the (typical) research focus. These are intriguing, thought-provoking, and interesting ideas. But are they enough to shed some of our professional baggage? I’m a bit skeptical, but I do agree that some pretty fundamental paradigm shifts are required if we want to shake up the system, and see Professors placing higher value on teaching improvement.

Why care about Higher Education? (Quebec, please listen)

I don’t usually get political with my blog but this issue of Higher Education in Quebec is too important to sit back passively. The Provincial Government of Quebec is imposing budget cuts to Universities, and the manner in which these cuts are being imposed is irresponsible, disrespectful, and the demands are untenable. As is discussed by my Principal in her letter to the McGill community, Universities are expected to cut budgets before the end of this fiscal year (an unprecedented challenge), and this was only brought forward in December. No institution in its right mind would change the course of budgets mid-way through a fiscal year.

This makes me angry and frustrated because the cuts will affect people and will affect the ways we do our jobs. They will affect livelihoods, morale, and they will affect services to students. Universities in Quebec will struggle with recruitment of students and professors, and struggle with retention. These budget cuts will have wide-ranging and long-term consequence for Higher Education in Quebec.

It’s time to reflect on the important question that is at the heart of this discussion:

Why care about Higher Education?

Caveats: this list is not exhaustive, and it is certainly not complete. These are my opinions, and I do not have expertise with all of the points I have raised - rather, they are my observations, ideas and are based upon my experience working at McGill for over 10 years. Please share, add to the ideas, and comment.

1. Creating Leaders: My institution is helping in the process of educating creative thinkers, good communicators, and global citizens. Our society need people with these characteristics as we move towards a difficult and uncertain future - a future with wide ranging environmental problems; a future with strife and conflict; a future with much economic uncertainty. We need young people to become leaders, and regardless of their discipline (biology, economics, physics, etc) the individuals coming out of my institution will become these leaders. We cannot turn our back on our students - we have a responsibility to continue to create and support a positive environment of higher education that will help train the the decision-makers of the future. At our doorstep are complex problems that need individuals with creativity, curiosity, imagination and motivation - the sorts of characteristics that I see in the students in my lectures and in the students in my laboratory.

2. Creating Communities: I work at a small campus that has a broad reach. Some examples: we have an Apiculture association that is developing workshops about beekeeping - an art and a science that we must understand and foster as we recognize the value of pollination for the food we eat. We have a working farm - a farm that invites school kids from the local area in to see the process of farming: work that is often rural and less accessible to people living in cities. Professors in my Faculty give seminars about their work and invite anyone with an interest to come and listen to how we are working to solve global problems. Higher Education is more valuable now that it has ever been in the past. Universities are becoming places with a focus and appreciation for outreach - outreach into our communities - our surrounding towns, schools, and community centres. Universities are more than lecture halls filled with students. Universities are more than Professors talking to each other and writing research papers for their peers. Universities are part of fabric of our communities and integral to the well-being of our communities.

3. Creating Knowledge: The beauty of higher education institutions is that they provide a home for the creation and dissemination of knowledge, and a kind of knowledge that can be gained from the intangible, the curious and from the process of reflection. Although funding systems have changed, the job of a tenure-track Academic is stressful, and we are busy, I still think that most academics have some freedom and a bit of time in their jobs that allow for that pure and amazing process of ‘thinking about neat stuff‘. Knowledge is dynamic, and knowledge is a product of the times we live in. Knowledge cannot be generated with cookie-cutter approaches or prescriptive top-down directives - my University still allows some flexibility and freedom to engage in the process of creating knowledge. That’s a very, very good thing.

4. Creating Friendships: I have coffee with colleagues who have become my friends. I see my Departmental administrative assistants every day - we talk about how the hockey practices went over the weekend - we talk about the local ski trails. We discuss the fun and frustrating things that happen in our lives. Students move through the system, but some become friends over time. Students who have long graduated have come back to say hello - we talk about what they are doing now, and about how their little brother is going to come to University because he has heard so many great things about the place. We discuss how they see the world after graduation, and talk of dreams and ambitions. Like any good workplace, my Department is more than faces and names - my Department is about people and about friendships. This is what happens inside the building and in the hallways of Universities. Expanding this - my University supports lives - it supports my family and the families of my friends at my workplace.

5. Creating Economies: There are strong economic arguments about the value of Universities to the economies of the region and province and country in which they operate. Students rent apartments and buy groceries, employees of McGill travel to conferences, and pay for taxis to and from the airport. We cater meetings, and drink a lot of coffee. We get business cards printed, we need to buy paper, computers and phones. Universities help make small, local businesses become successful. On a bigger scale, our research programs are catalysts for larger economies in our cities and in our province, whether they be advances in medicine or solutions to global food security. Graduates from our Universities go on to become lawyers, CEOs, and they build businesses and create opportunities for thousands. Universities support and create economies - big and small.

Yes, higher education is about creating great things that are much bigger than the footprint of the buildings we work in. Higher Education has values that are far beyond the curriculum and far beyond esoteric, and intellectual pursuits.

To the Parti Québécois: making rash, and ill-thought decisions about funding to Universities is a serious mistake. I urge you to step back, reflect, and move carefully with rethinking the budgets of Universities. As my Provost stated, your economic approach is an assault on higher education, and this is truly alarming.

To my colleagues, my students, my friends: please speak up. Please raise your voice and be heard. Let us stand together as a community (this is starting). Let us ensure higher education remains a central part of Quebec. May we continue to create great things.

There is an upcoming summit about the future of Higher Education in Quebec. I sincerely hope that part of the discussion can reflect on the bigger question about the value of Higher Education in this exceptional and incredible province.

The greatness of pseudoscorpions

As you know, I’m quite passionate about Arachnology, from spiders, to harvestmen and Pseudoscorpions. These are all some of the creatures that fall into the category of the ‘obscure and amazing‘. On the topic of pseudoscorpions, a few very fun and interesting things have happened recently, and enough to warrant a short blog post. I also promised that I would post a few more videos related to some research activities on the hunt for pseudoscorpions in the Yukon.

1. Just look at this SEM of a pseudoscorpion!

A little while ago, my Arachnid friends and colleagues from Alberta, Heather Proctor and Dave Walter, forwarded me a stunning image of a pseudoscorpion taken with a scanning electron microscope (SEM). Dave was kind enough to give me permission to share it here:

SEM of a pseudoscorpion (Chernetidae) - copyright D. Walter (reproduced here with permission)

SEM of a pseudoscorpion (Chernetidae) - copyright D. Walter (reproduced here with permission)

There really is something lovely about getting up close and personal with these little Arachnids. I don’t know this species, but it’s definitely in the family Chernetidae - a relatively diverse family, quite common across Canada. My favourite Yukon species, Wyochernes asiaticus, is also a Chernetid. Dave Walter really does some magic with his SEM images, and you are encouraged to check out is macromite blog (his home bug garden blog is also worth a peek!).

2. Just look at these videos about collecting pseudoscropions in the wild!

Speaking of my favourite Yukon species, I took a lot of videos of field work in the Yukon last summer and I wanted to share a few with you, here. Although our larger purpose for the trip was to complete some follow-up field work for the Northern Biodiversity Program, I also wanted to collect additional specimens of a wonderful pseudoscorpion species. The first video provides some context to the work, and gives you a bit of a flavour of the landscape up near the Yukon - Northwest Territory border in Canada:

Typically, pseudoscorpions are not that commonly encountered. In my experience, when they are encountered, you tend to see one or two. What is truly amazing is the sheer abundance of this species found under rocks in creek/river beds in the Yukon. Furthermore, you can see and collect multiple life stages, including females with eggs. This short video gives a taste for this abundance.

The third and final video is a big goofy, and highlight the ‘collecting gear’ and appropriate field attire for becoming a “pseudoscorpion hunter“. I am continually on a crusade to help generate enthusiasm for Arachnids, whether it is dispelling myths, or trying to inspire others to become Arachnologists (you know, we do need Arachnologists in Canada!).

One important caveat: you may NOT simply run to the Yukon and flip rocks to collect pseudoscorpions - many parts of the world, including the Yukon, have strict guidelines about what you can collect. Permits are required, and be sure to check into this before you plan on becoming an Arachnologist!

3. Just look at this pseudoscorpion necklace!

To further illustrate my rather quirky obsession, I managed to find a wonderful person on Etsy who was able to make me a pendant with a pseudoscorpion design:

The pseudoscorpion necklace.  You want one.

The pseudoscorpion necklace. You want one.

Not only that, this design is actually from a photography I took a few years ago, and is an accurate depiction of the cosmopoliton species Chelifer cancroides.

Chelifer cancroides - my photo which was used to design the pendant

Chelifer cancroides - my photo which was used to design the pendant

I KNOW you want to get yourself one of these… start a conversation with Lynn. Get yourself one of these necklaces and stand proud with other pseudoscorpionologists!

In sum, I do hope you find this post interesting, hopefully fun, and has whetted your appetite from more information about curious critters.

Stay tuned… I will continue to post more about Arachnids…

Careful what you say in lecture: a tale of tweets, ice-storms in Quebec, and population ecology

While discussing age pyramids in my ecology class last week, I mentioned that there was a mini baby-boom in Quebec following the 1998 ice storm. In other words, after an extended period of time without electricity, more babies were conceived. This is one of those ‘urban myth‘ stories for which I had no data to actually discuss whether this was fact or fiction, but it was mildly amusing, and certainly related to the discussion we were having about population ecology and the effect of the baby-boom generation on Canadian demographics.

I expected this story to stop there, but a savvy student in my lecture tweeted what I had said (yes, there are definitely pros and cons of being an active participant in social media, including twitter). I was being called out, publicly, about my casual comment in lecture. This forced me to look to the data and test my hypothesis that the birth rate in Quebec may have been higher after the ice storm of 1998.

Screen shot 2013-02-08 at 9.26.15 AM

Data required? Yearly population estimates of areas affected by the ice storm (i.e., numbers of females), and number of births in these regions.

Thankfully, these data were readily available. However, not all data were tabulated in the same way by geographic region in the Province. This meant that I had to narrow down the region to just the island of Montreal (thankfully one of the more populated parts of the province). I took the number of births, divided by the number of females to get a per-capita rate of births per female per year in Montreal, and I looked at the years from 1997 through to 2000.

I predicted that if my hypothesis was true, birth rates would be higher in late 1998, therefore if data were collected properly, the ‘boom’ in births would likely be in that year (…or possibly in 1999).

Here are the results:

1997: 0.012 (babies born / female)

1998: 0.012 (babies born / female)

1999: 0.011 (babies born / female)

2000: 0.011 (babies born / female)

So, the data do not support the hypothesis that the ice storm resulted in a higher rate of births in Montreal.

Caveats? There are a lot. I have made quite a few assumptions, and my methods are partially flawed… I do expect students in my class to think about this…

Two other points to mention:

First, while searching for information about population-level effects of the ice storm, I came across a McGill press release about how babies born during the ice storm may be stressed later in life - Interesting! And also somewhat counterintuitive to what I originally proposed in lecture.

Second, (and less related), we must be wary of these myths - they pop up all over the place (e.g. increase in births after the publication of Fifty Shades of Grey?), but without a more detailed look at the data, we must be careful what we say. Thankfully the urban myth about mini-baby booms and power outages are debunked with some regularity.

In sum, I learned an important lesson. Careful what you say in lecture.

…and thank you to my student who forced me to look more carefully into the story of the ‘ice storm babies’

Why Professors can’t relax (even if it will make us more productive)

This past weekend, as I was struggling to get some work done on a Sunday morning, I read Tony Schwartz’s opinion piece in the New York Times, titled “Relax! You’ll be more productive“.

I read it with curiosity and amusement. I also discussed it with my wife, had a few discussions with people over twitter, and the more I thought about it, the more I decided it warranted a bit of a rant, and required placing Schwartz’s piece in the context of Academia.

Schwartz points out that “Human beings aren’t designed to expend energy continuously“, and we can be more productive (i.e., in the sense of doing work well) if we were able to find time to chill-out, relax, and maybe taking a nap would be a good idea. This does make sense! Being overtired can lead to mistakes, causes our the fuses to be short, and certainly can cause us to take longer at doing our jobs - even simple tasks can become difficult in the face of a life filled with too much of the ‘go go go’. Why don’t Professors take mid-afternoon naps? Heck, can’t tenured Professors relax and ‘do less’ whenever they want?

A nap? Really? BWAHAHAHA! This is priceless. How abut a dose of reality.

I am a Professor, and this job is absolutely wonderful, but it does require (yes, REQUIRE) a busy schedule and a lot of time. Time management is a big part of my job, and the days are full of teaching responsibilities, grant-writing, meetings with students, administrative responsibilities and writing manuscripts. Contrary to what Forbes might lead you to believe, the life of an Academic is not stress-free and is not all tweed-jackets, and hobnobbing at the Faculty club. A lot of the stress is positive stress, but there is stress, and finding time to relax during the workday is an impossibility given the current context of University.

I fully appreciate some of the ideas behind Schwartz’s piece: taking a mid-day stroll outside (like Darwin did each day!) , or a quick nap in the afternoon, would be good for me, and would probably help with productivity but the reality is that there is no time. And I just can’t make the time appear. It’s the ultimate limiting resource. When I do have time that is freed up during the work day, it gets filled with tasks that are deemed important but not urgent.

How about the the #worklifebalance. Many people with jobs also have families and commitments at home that compete with the resources of time and energy.

Is this familiar to you?

Time to get the kids to dance class and Music lessons. Homework hell around the kitchen table? Phew. Dinner’s done. How about kitchen clean-up? Who will fold the laundry? ….finally, it’s time to fall exhausted on the couch at the end of the day. Ahhhh sleep…glorious sleep. 6 AM! Up we get, let’s get lunches ready! Where’s that permission form? The bus is coming, you’re late! Shoot - I’m late too. Gotta run… have a great day!

My wife pointed out that Schwartz’s argument really doesn’t apply to jobs in which it takes X amount of time to do a task, and if you are in a business that is dependent on consumers buying your product, if you sell Y more units of your product, it will take X x Y amount of time to get the product out the door. There is not really a choice - you can’t relax and do less, If you did less, you won’t have a sustainable business. As some of the reader’s comments in Schwartz’s piece state: ‘relaxing’ is simply a luxury that most people can’t afford.

I like this quote from Schwartz’s piece: Paradoxically, the best way to get more done may be to spend more time doing less

YES! I do agree. I buy into the ‘why‘ but I can’t see the ‘how‘: if less time is spent on one task, this frees up a bit of time, and it will get filled right away. (and never mind the fact that GUILT will come into play - I really would feel rather guilty if I shut my office door for a 20 minute shut-eye each afternoon…even if that chair is in the corner of my office is really, really comfortable).

A nice place for a nap.

A nice place for a nap.

Academic Institutions could be model systems for re-thinking the workplace and how to consider ways to help employees find time to ‘relax’ on the job, and that will surely have many benefits. This will, however, require a paradigm shift, and require a complete re-thinking of the ways the tenure-track system works, and the level of expectations put on Academics. This could be a great discussion to have, and let’s have it. But let’s not start this discussion with a goal that is untenable. I am quite sure that my colleagues would have a good chuckle if they were encouraged to ‘relax’ and have a little downtime during the workday.

Let’s start with some things that are a bit smaller and more realistic.

Let’s work our timetables so that lunch time can be free of classes; let’s find ways to encourage people to eat in a common area instead of in front of their computer. Let’s make sure offices, labs and coffee machines are suitably arranged so that people move around, communicate, and find a bit of time to sit with colleagues and students over a cup of tea. Let’s be sure that Chairs and Deans give tenure-track staff the right kind of mentorship so they can be productive on the right kind of tasks, and the flexibility and support so they can find the right balance between the various duties of academia. Let’s recognize, up front, that negative stress, overwork, e-mail hell, and pressures on time are real problems that require real solutions. If Academic institutions want to be places of higher learning, there must be support and a recognition that ‘down time’ to ponder, discuss and be curious is time well spent.

Well, with that, I’m going to go out for a walk - actually a run - a run to the lecture hall because I’m running late.

Postscripts:

First, I sincerely hope this post does not come off as sounding like I’m whining or complaining. I’m not complaining - I love my job and I wouldn’t trade it for anything.

Second, you might ask how I found time to write this blog post. That is more difficult to address - sometimes the really fun things to do can be done quickly, and it seems relatively easy to find a few minutes to write something I am passionate about. I also seem to get some very positive energy from this exercise. Hmmm … maybe writing a blog post is my way to relax?

Where are all the Arachnologists? (and why you should care)

Canada is a big country, with an amazing diversity of habitats, from the temperate rainforests of Vancouver Island, to the polar deserts on Ellesmere Island. We are a country that harbours thousands of Arachnid species (yes, our eight-legged friends!). Some examples: the Yukon Territory hosts over 300 spider species and over 150 species of Oribatid mites; Quebec is home to well over 600 spider species. The Alberta Biodiversity Monitoring Institute has documented over 200 species of Sarcoptiformes mites from a relatively few number of sites in Alberta, and their work is far from complete. The Canadian National Collection of Insects and Arachnids in Ottawa has one of the best spider and mite collections, world-wide.

The general public is fascinating by Arachnids: my post titled ‘Spiders do Not Bite continues to get hundreds of hits every week. We link comic-books and superheroes to Arachnids (even if the anatomy of spiderman is all wrong…). Spider silk is used to make dresses, violin strings, and has potential in pest control. There are invasive spider species that go unnoticed, yet may affect native species - as Bednarski, et al (2010) have documented in Maine. Spiders continually show up in grocery stores and cause alarm and fear (although mostly not warranted..). People are often picking ticks off their pets, or hearing about lyme disease.

Everyone has a story to share about Arachnids.

Recently, the Class Arachnida was a lunchtime topic of discussion in the lab. This discussion was in part prompted by an email I received from Leslie Brunetta. She asked the question about how we can promote Arachnology in University education. One way to do this would be for Arachnologists to agree to deliver guest lectures in organismal biology classes, and this got us into a discussion about how many people get paid to work on Arachnology in Canada.

I tried to estimate the number of people in Canada who spend a significant portion of their time getting paid to do things with Arachnids - and I consulted a lot of colleagues to get this done. This would include academics with a research focus on Arachnids (from behavioural ecology to biodiversity science), and government scientists working on Arachnids (from systematics through to the use of mites as biological control agents). This does not include graduate students, nor does it include people working on short-term contracts. I estimate that fewer than 20 people are paid to work on Arachnids in this country. This is truly astounding and astonishing. Arachnids include two Orders that are among the most diverse on the planet: combining the Acari (mites & ticks) and Araneae (spiders) gives you estimates of well over 85,000 described species, globally. There are only a handful of Insect Orders that are higher.

Let’s revisit why EVERYONE should care about Arachnids and why Canada ought to have more Arachnologists:

Spiders are key predators in agroecosystems (the classic paper by Riechert & Lockley 1984 is quite relevant!). Spiders eat mosquitoes, including those that can be vectors for malaria (Nelson & Jackson 2006) . Spiders are key prey for highly valued vertebrates (Gunnarsson 2007). Spiders can be medically important - their venom has remarkable potential for drug development (Rates et al. 2011).

Mites are everywhere - they play critical roles in decomposition of organic matter (Kampichler & Bruckner 2009). Plant-feeding mites are economically important for dozens of crops. Follicle mites are in our heads (Elston 2010).

Ticks can transmit diseases that are very important for human health and well being (Sperling & Sperling 2012). Ticks can hurt our beloved pets (Blagburn & Dryden 2009). Ticks can be harmful for wildlife populations (Addison et al. 1994).

Need more convincing?

Arachnids are stunningly beautiful; they are among the ‘small and obscure’ creatures most worthy of study. In addition to mites, ticks and spiders, we can’t forget about Opiliones, Pseudoscorpiones, Scorpiones and other Orders… Arachnids should adored as much as Pandas, or the Mona Lisa.

CANADA: THIS IS A CRISIS! We must find a way to ensure Arachnologists get paid to do Arachnology in Canada. The most obvious place to point is the CNC. It is unacceptable that a spider taxonomists has yet to be hired to maintain that spider collection. We should be embarrassed. Taxonomists are needed in Canada, especially for dominant arthropod groups. The Canadian Council of Academics makes this point quite clearly in their report on Canadian Taxonomy:

Job openings in taxonomy have virtually ceased and research funding is stagnant. Canada’s international contribution to new species descriptions has fallen from 6th in the 1980s to 14th in the 2000s.

Oh Canada.  Where are your Arachnologists?

Oh Canada. Where are your Arachnologists?

I realize that many other taxonomic groups remain understudied - However, I am discussing an entire Class of animals! Could you imagine if I were discussing Mammalia, or Reptilia, or Insecta? There would be an uproar.

Let us work to fix this. Let’s train excellent Arachnology graduate students, let’s lobby Departmental Chair, Deans, Bureaucrats in Government, members of Parliament, and whoever else will listen. MUST Listen.

Our eight-legged friends need our help.
