Social media in higher education: a teaching and learning project

This term I will be spending some time with Teaching and Learning Services (TLS) at McGill: instead of doing my normal winter teaching, TLS is offering me a home for 2-3 days a week to work on projects with them. This is an outstanding opportunity as it provides real and significant time to work on teaching innovation. In my opinion, teaching in higher education should constantly be evaluated and re-assessed, and all Professors (regardless of career stage) should be supported and encouraged to improve, change and innovate their teaching. However, I would argue that many institutions put more attention on research productivity rather than supporting teaching innovation.  This is not to say that Universities don’t value teaching, but rather an argument that promotion is often weighted more towards research productivity than developing innovative approaches to teaching. There is also sometimes a culture by which Professors are unwilling to change anything about their teaching because of fears related to how this might affect teaching evaluation scores.  I have written previously about barriers to teaching innovation, and another barrier is that Professors aren’t typically supported to take time away from other duties to work on projects related to teaching and learning. Sabbaticals, for example, are mostly about re-inventing or re-tooling a research program and less often about pedagogy.  Over the past several years I had these kinds of discussions with various TLS colleagues, and the result is that I now have meaningful support to invest some of my time and energy towards teaching innovation. Bravo, TLS! I’m delighted to be spending time with you this term! (and a sincere thanks to my Chair and Faculty for supporting this endeavour).

It’s fitting that I’m using a blog to discuss the main project I’ll be delving into this term, because it will be all about the use of social media tools in teaching and learning. The way that we teach is changing, in part because there are countless new tools to use; tools that may help with interactions among students or between instructor and students, or tools that help us interact with dynamic, ever-changing content.  It can, however, be overwhelming. There’s an onslaught of technologies (….clickers, video-conferences, tablets, smart-boards and more) as well as countless on-line tools (… Facebook, Google hangouts, blogs, twitter, on-line discussions, etc). How do we make sense of this? How do we incorporate the correct tools into our courses in an effective and productive manner? What ethical or privacy issues must we understand when using some of these tools in the classroom?

My project will try to make sense of all of this, and over the next several months, I will be reading, talking, tweeting, blogging, seeking, sending, writing (and more).  I will be looking to the literature to assess the ways that social media tools can be used effectively in the classroom; I will survey current practices at various institutions, including McGill. At the end of the day, I hope to produce a dynamic ‘document’ to be shared and used by all those who are interested. This document will cover best practices, provide some case-studies and examples, and provide some guidelines about effective use of social media tools in teaching and learning.

Now I shall ask for help: Please let me know about the sorts of social media tools you use in the classroom. Drop me an e-mail, or comment (below), or tweet at me. I hoping to gather examples from a range of disciplines, using a range of tools, in a range of settings (small seminar classes, large courses, field courses, labs). Send me papers you might have written, or links that I’ll need to look at. The products from this project will only be strong if a community can be involved in its development, from the start.

Thanks everyone: this will be a terrific project, and thanks again to TLS and McGill for supporting this project..

The effect of insecticides on jumping spider personalities

This post was written by C. Buddle and R. Royaute (a PhD student in the Arthropod Ecology lab).

We are pleased to announce a recent publication from our lab, titled Interpopulation variations in behavioral syndromes of a jumping spider from insecticide-treated and insecticide-free Orchards.  As is traditional in the lab, here’s a plain language summary of the work:

Agriculture has strongly intensified in the last 60 years, causing major concerns the sustainability of biodiversity. Agricultural practices can reduce habitats available for wildlife and also release toxins in the environment through the use of pesticides. Not all organisms living in agricultural fields are harmful, and many predators, including spiders, can help to reduce pest density. We have a relatively good knowledge that the diversity of spider species in agriculture, especially under our temperate latitudes, can help reduce pest damage. However, many of the factors that influence spider predation on pests depend on the outcome of behavioural interactions and we don’t know much about that topic. Spiders are often cannibalistic and aggressive with one another and these types of behaviours may limit their efficiency for pest control. We also need to understand if these aggressive tendencies vary depending on the type of agricultural field considered, a pesticide treated field may favour very different behaviours than one that is managed organically. Another important point is that populations are composed by a multitude of individuals, each with its own behavioural tendencies. Some individuals take more risks when confronted with predators (i.e. they are more bold), others are more active and explore larger areas or consume more prey. These tendencies – often referred to as personality traits – may also be correlated with one another.

In the context of agriculture, this may mean that certain individual spiders may contribute more to biocontrol because they consume more prey, or that certain individuals are more at risk of being in contact with pesticides because they are more active. To understand, how agricultural practices, and particularly insecticidal applications, affects personality and behavioural syndromes in spiders, we focused on the jumping spider Eris militaris, an abundant and charming jumping spider occurring in apple orchards in Quebec. Here’s a lovely photo from Crystal Ernst to illustrate how attractive they are: (thanks, Crystal, for permission to post the photo here!)

We collected spiders from pesticide-treated and pesticide-free orchards, brought them back to the laboratory, and did a number of behavioural tests on the individuals from the two populations. Compared to the insecticide-free populations, we document that individuals from orchards that did receive insecticides experienced a shift in their behaviours syndromes. The overall shape of this syndrome is multidimensional, but it suffices to say that the correlations among different behaviours (the ‘syndromes’, otherwise known as the ‘personality’) differed depending on where the population came from.

In sum, the personality shifts that we documented for E. militaris are potentially quite important since the relationships between different behaviours may affect a spider’s ability to be an effective generalist predator in apple orchards. We need to consider how management  (including use of insecticides) may affect specific behaviours, and more importantly, the relationships between the different behaviours.

Expiscor (11 Nov. 2013): Changes

Expiscor is moving!

It’s been fun bringing you Expiscor each week, but things are changing and this blog feature has found a new home. Starting later this week, I’ll be blogging over at SciLogs.com.

Yes, I’m excited. 

Excited!

Excited!

It is truly an honour and a thrill to be invited to join the cast of impressive science bloggers, from Malcolm Campbell and his “Six Incredible Things Before Breakfast”, to Paige Brown’s “From the Lab Bench” to GrrlScientist’s “Maniraptora” and  Matt Shipman’s Communication Breakdown 

Expiscor will also change its style; I don’t provide nearly as good a “link-fest” as other people do (e.g., Ed’s and Malcolm’s are amazing!) and so instead of a weekly set of links, I will bring what I view as a short-list of fascinating discoveries, mostly from the world of Arthropods. These highlights, to be posted on Monday (as usual), will be more than a list, as I will try to provide a bit of context and opinion around each story. I see opportunity in the blogosphere to highlight new findings, stories, and photos related to the natural history and biology of spiders, insects, and their relatives.  In addition to these weekly highlights, I will write semi-regular long-form posts, again with a focus on arthropods, and some of these will be cross-posted on arthropodecology.com.

Don’t worry, you’ll still see amazing photos on Expiscor, like this one from Nash Turley:

You might wonder why I have opted to move Expiscor from its current home to a community blog. For me, it’s about continuing to improve and expand the blogging side of my academic life, and working alongside the other bloggers on SciLogs.com, I think, will help further hone my skills. More importantly, however, is that this move will allow me to reach out and connect with a very broad and interdisciplinary audience. Science communication, to me, is all about continually pushing the limits, expanding, thinking about and re-working the ways to bring exciting scientific discoveries to the world, and SciLogs is exactly aligned with this belief, as its mission statement highlights:

The SciLogs combine the strengths of both science culture and the blog medium. They provide scientists and those interested in science with the opportunity to interact in interdisciplinary discussions about science in all its forms… 

ArthropodEcology.com will remain active, although it certainly won’t be as active as it has been over the past year. The original idea behind the arthropod ecology blog was to highlight research activities within my laboratory, and to provide a forum for writing and discussing Higher Education. It’s grown a lot since then, and in some ways, the site will return to its roots, and I hope to get my graduate students and other people within my local community interested in writing their own posts under the arthropod ecology banner.

To my loyal readers, followers and friends: I must thank you for continued interest and support. The community of people associated with this blog is truly tremendous, and you give me energy, ideas and support every day. You help me uncover fascinating stories, provide me with terrific content, including photographs. You have made me a better scientist and a better person.

In sum, I pledge to continue to fish out discoveries and bring them to you; what’s changing is the location, and I do hope you will keep following along over at Expiscor’s new home.

And I know you want it… here’s your tweet of the week, from Minibeast Mayhem. Yeah, invertebrates are awesome.

Tablets in the forest: using mobile technology in Higher Education

I am pleased to present a publication that came out earlier this week in Educause Review On-line. This article resulted from a pilot project done in Fall 2012, in which students in my field biology class at McGill used tablets to enhance experiential learning.  Authors on the paper included colleagues from Teaching and Learning Services at McGill (Adam Finkelstein and Laura Winer), and PhD student Crystal Ernst.

Here are the ‘take away’ messages from the project:

  • Environmental biology students mobile devices to gather rich data in the field and to support learning through real-time interaction with their instructor and the larger research community.
  • The project included an analysis of survey and interview data to determine the impact of tablet use on student engagement once the project was complete.
  • Students recognized the value of the tablets as a research tool; however, the tablets’ most important contribution to learning was the real-time communication and feedback they enabled between students, instructors, and the scientific community.

Stated another way, tablets are wonderful to use, and can be effective tools in a field biology course, but the students felt connectivity (which facilitated communication) was essential: the mobile WIFI units paired with the tablets made the project successful.  Here’s a quote from the paper to further illustrate that point:  “most students (53 percent) reported that the tablets increased their interaction with the instructor and TA. This was corroborated by their responses on tool use: 72 percent of students thought that live communication with the instructor and TA helped develop their skills.”

I previously highlighted a video from that project on social media use in the class, and the video (below) is more specifically about the use of the tablets in the class.

This work was done in collaboration with Teaching and Learning Services at McGill, McGill Libraries, and the tablets were generously provided by Toshiba Canada, and Bell Mobility helped us with mobile WIFI units.  I am immensely thankful for the support and I am truly honoured to be able to explore these adventures in teaching and learning.  We are continuing with these kinds of initiatives, and a Brown-Martlet Foundation grant has allowed my Department to purchase some of the tablets originally used last year.

Expiscor (4 November 2013): the obscure edition

Last week I had a terrific discussion with a twitter friend, and he suggested that many/most of the links on Expiscor are ones that were VERY frequently discussed over various social media sites – i.e., a re-distribution of commonly viewed stories. Of course, that is part of the objective of Expiscor, but I also want to be a provider of stories people haven’t heard about previously. So, CHALLENGE ACCEPTED! This week my goal is to provide links to things that are so weird, and obscure that you will totally surprised. It’s the obscure edition….  Please take the poll at the end of this post to let me know if I succeeded!

Why undergraduate students are teaching my entomology course

This term I’m teaching an introductory Entomology course at McGill. These days, however, I’m not lecturing at all – the students are doing the teaching. For the past couple of weeks, and for the next couple of weeks, groups of students are lecturing on the part of the course called ‘overview of the insect Orders‘. Typically, this section of the class is a little dry for one person to teach – it’s a standard series of lectures on the Insect Orders – and covers the  evolution, phylogeny, biology, ecology and economic importance of the Insect Orders, starting with Collembola and moving through to the ‘Big Four’ – the Lepidoptera, Hymenoptera, Diptera and Coleoptera.

This term, I decided to turn the tables, and students became the professors. They provided me ideas on what Orders they were most interested in, and based on their feedback, I assigned them to groups and scheduled who would teach what. I also provided them a detailed outline of what was expected. This is not a trivial task – preparing lectures, and lecturing, takes an incredible amount of preparation and time and energy. These lectures are graded (with a rubric), and thus in addition to the peer/instructor pressure for students, this part of the course is part of their final grade.

Here are some refections about the process, so far:

Perhaps what has struck me most with this experience is that the students are delving into the content to a level that I would not have done on my own – in part because I simply would not have the time if I was lecturing on all the Orders. The students, by becoming ‘experts’ on a topic, have more time to dig out the most interesting and fascinating facts about the Orders. They are hunting down the true controversies surrounding the systematics of different Orders, and presenting them like seasoned veterans.  They are taking ownership over the topics, and with such ownership comes responsibility, and pride.

Lecturing is so much different than the typical short-format presentations that students are used to. They have plenty of experience giving presentations to their instructors and peers, but these are seldom more than 15 or 20 minutes. Filling up 50 minutes is a very different ball game. It requires a different set of presentation skills – skills related to thinking on your feet, preparing for unanticipated questions from the audience, and experience with a more spontaneous form of science communication. In my experience, these skills are seldom developed during an undergraduate student’s academic program.

What is also evident with this process is that the students are having FUN with the content and FUN with the lectures. They are linking to the best videos and images for their Order – they are challenging each other with who can find the most fascinating facts about a particular Order. They are smiling, laughing, and genuinely passionate about what they are presenting.  They are also deeply supportive of each other – they ask good and fair questions, engage with the content, work to make the experience positive for everyone. (by the way, I have been tweeting some of the fun facts from this course using the hashtag #ENTO330 - please follow along!)

The education literature supports the ideas I have written above, and the overall process is defined as ‘peer teaching‘.  As the title of Whitman and Fife’s report states “to teach is to learn twice”  , and although caution is warranted when executing peer-teaching, that report does highlight the fact that learning can occur effectively under peer-teaching scenarios. More recent literature from Dioso-Henson (2012)  shows that “reciprocal peer tutoring” (i.e., students run tutorials instead of instructors) “produced significantly larger academic gains than traditional classroom instruction“.  Those interested in delving into the Education literature on this topic should see Topping’s (1996) article.

Now, what I have not provided here is any perspectives from the students, and Graham Scott correctly pointed this out to me. Once the course is over, I will bookend this post with another post containing some refections from students. It’s important to see whether or not my positivity is a reality from their perspective! So, stay tuned for that!

In sum, we often talk about Higher Education being about teaching and learning, with the assumption that the teaching is done by a Professor and the learning is done by the student. Peer teaching, I believe, is a valuable method by which undergraduate students can be fully immersed in the process. The learner can become the teacher and this makes the experience so much richer, for everyone.

Instructors: please contact me if you want more details on this process. I will be happy to share the details – assignment overview, grading rubric, etc.
