I’d like to introduce Dr. Blake Bextine, an associate professor at The University of Texas at Tyler who specializes in the interactions between plants, insects and pathogens in agricultural ecosystems. While at the Entomological Society of America meeting in Reno last fall, I had the opportunity to hear Dr. Bextine speak on his use of Facebook to facilitate undergraduate student learning. I thought it was an interesting discussion and so I invited Blake to share his ideas here.

The statements that will be made in this article should be prefaced by saying that I have mixed feelings about technology in the classroom. On one hand, I am a strong believer that the one-on-one interactions between the student and teacher or between a student and another student are very difficult to replicate with technology. On the other hand, technology can facilitate these interactions by adding a forum where students that traditionally do not participate are more comfortable. I also teach in the sciences, not any other subjects, so I cannot comment on the outcomes of using technology (strictly on-line delivery) in other disciplines.

At the 2011 Southeast Branch ESA meeting I spoke at a session on Technology in Entomology Teaching and took the hardline against on-line teaching but heard several talks from people that have has much success using alternative delivery methods. Realizing that I had not taught this way before, I decided to give it a shot in the Fall 2011 semester in my Cell Molecular Biology class at the University of Texas at Tyler. I took a summer coarse on Technology in the Classroom and was ready to go with my new hybrid lecture course (50% in class/50% on-line) when the year began. I found both good and bad things came from my experience. One positive that surprised me was that students whom were usually quiet in class were more vocal in on-line discussion. Student comments were also easier to track and participation was easy to monitor. I found my way to engage them by tracking them. A negative that surprised me was that it was easy for me to start a discussion and then let the class go, which lead to me stepping away and engaging with them less. This brought a dilemma that I had not previously considered…we always talk about “student engagement”, but what about “teacher engagement”?

So, I think we have much to think about with respect to technology in the classroom. There is no “one size fits all” answer to being a proponent or opponent of the new teaching methods. To use a few clichés, we are operating in the “new normal” and there has been a “paradigm shift”. We need to utilize technology when it fits and avoid using it simply because it makes economic sense.

A major point that needs to be considered is what technology we should utilize. I have seen classes where students have to learn to use three computer programs to access class content. Often, we think students in this current generation all know how to use every type of technology we can throw at them…they don’t. In fact, many have limited knowledge, often not past using Apps on their smartphone. That is why I like to utilize technology that they are familiar with, like Facebook. It is free, almost everyone has seen it, and most people check it often throughout the day. The result is no learning curve and very fast adoption at the beginning of the semester. It provides a platform to post media, articles, and comments while organizing the posts in chronological order. Facebook is currently used in all my classes as well as my research laboratory. It has become the central way we keep in touch. In short, I am utilizing technology to better engage the students by meeting them halfway with “their” technology and as a side product, I have become better engaged in the process.

Today’s guest post is by Stephen Luk, the lead author of Fireflies of Ontario (Coleoptera: Lampyridae), which was recently published in the Canadian Journal of Arthropod Identification. Stephen is an M.Sc. candidate at the University of Guelph as part of the Insect Systematics Lab, and while his main research is now focusing on Sphaeroceridae taxonomy, he has maintained a keen interest in the remaining Insecta. Stephen is a frequent contributor to BugGuide.net, and an avid nature photographer.

Lampyridae - Lampyrinae - Photinus obscurellus (m) - Stephen Luk Firefly

Photinus obscurellus by Stephen Luk

Over the moist meadows where stargazers behold the star-studded sky, insect enthusiasts can admire the summer scintillations of fireflies. Their neon glows spark fond childhood memories: of fields lit by symphonic displays; of brilliant twinkling in a jar set among the grass or over a book. But the fireflies of lore and poetry are truthfully poorly understood. They are often difficult to identify both in the field and in the laboratory. The shape and colour of a species can vary bewilderingly, and only an informed observer is capable of confidently identifying species amid the dazzling nocturnal orchestration. This is said of adults, and scarcely of immature stages, the knowledge of which is mostly sparse to absent.

Thankfully, the confusion is subsiding with the advent of novel identification tools. “The Fireflies of Ontario (Coleoptera: Lampyridae)”, published in the Canadian Journal of Arthropod Identification, features an updated list of Ontario fireflies as well as a comprehensive and user-friendly key to adult fireflies in Canada east of Ontario. Users will discover a practical platform upon which to illuminate the fascinating lives of fireflies. This resource arrived just as these wonderful beetles mesmerized the public with their seasonal light shows. Fireflies were certainly well represented this summer in southwestern Ontario — I observed nearly a dozen species upon a few occasions here in Guelph.

Behind the scenes with fireflies

I became acquainted with fireflies as an undergraduate student, and was appalled that creatures so familiar were so harrowing to identify. Thus, I assembled obscure literature, meticulously determined specimens and wrestled long with species in the genus Photinus (remarkably similar species in this region). I amalgamated and redesigned keys while gladly illustrating them with pinned specimens, but disapproved the paucity of suitable live images, and have since embarked on a quest to rectify this personally. The product was defended and published fourteen months later, rendering Ontario’s adult fireflies identifiable. I have since accumulated additional images, and was even privileged to dispense some expertise through the CBC.

Today’s special guest blogger is Jess Vickruck, a PhD candidate at Brock University. Jess studies twig nesting bee diversity and the impacts of nest choice on their biology.

When I first started my master’s project, my intention was to look at how nest choice affected fitness in twig nesting carpenter bees (genus Ceratina, family Apidae).  Little did I know that along with twigs full of bee larvae I would also get up close and personal with numerous uninvited house guests who all had one thing in mind – Ceratina are delicious!  Although my supervisor continually reminded me that my thesis was about the bees and not the species that eat bees, I wrote up the data, and lucky for me it appears in the 2010 edition of the Journal of the Entomological Society of Ontario.

I’d like to welcome Adam Brunke to Biodiversity in Focus as a special guest blogger today. Adam is a graduate student at the University of Guelph, and studies the diversity and agroecology of rove beetles (Staphylinidae) in Ontario.

North America’s insect fauna is changing rapidly. Many of us, however, are completely unaware of this: flies still land on our food, mosquitoes continue to feed on us and carpenter ants show up every year in our kitchens looking for something to eat. The truth is, something strange is happening to the insect communities in our backyards. So many foreign invaders have become established on this continent that it’s becoming a challenge in some places to find native species. In my experience this is especially apparent for beetles: firstly because there are so many exotic species here now; secondly because this is the group that I specialize in. If you casually surveyed your neighborhood for beetles, and sent the sample 100 years into the past to a taxonomist working in North America, they would probably complement you on your excellent reference collection of European Coleoptera!
