The best way to learn and encourage excitement in young people about science is through a hands-on approach. The EvolvingSTEM program provides a ready-to-implement hands-on curriculum for high schoolers to learn evolution, microbiology, basic biotechnology, and get excited about STEM research careers.
A local news outlet wrote a story on the benefits the EvolvingSTEM program grants to students who take the course.
The EvolvingSTEM program has spread to multiple school districts which have found that the hand-on experience provided by EvolvingSTEM has been more engaging and memorable to students than a simple course. The Cooperlab is an integral part of the program, and has made great strides towards making EvolvingSTEM more accessible to any school district willing to host EvolvingSTEM.
“[Vaughn’s] goal in my opinion, is he wants to teach the next generation about evolution in an inquiry-based, hands-on way. To help students understand what evolution is whether it’s to get a few more points on the Keystone [standardized exam], or you know just to have the concepts correctly integrated,” Kinchington said.
EvolvingSTEM was featured yesterday on the third segment of the The Confluence, a daily news show in the Pittsburgh area.
And Evolving STEM is a program that uses science and lab experiments to give students a hands-on experience with evolution. As schools across three states – including Pittsburgh Science and Technology Academy, a magnet school in Pittsburgh – adopt this approach, educators are asking how teaching evolution should change. Hear from a group involved with the program:
Vaughn Cooper, evolutionary biologist and director of the University of Pittsburgh’s Center for Evolutionary Biology and Medicine, and founder of the EvolvingSTEM Program; Edwina Kinchington, teacher at Pittsburgh Science and Technology Academy; Mia Perez, junior at Pittsburgh Sci-Tech; and Sachin Thiagarajan, junior at Pittsburgh Sci-Tech.
I’m honored to have been elected Chair of the Council of Microbial Sciences (COMS) of the American Society of Microbiology, which includes the representatives of all scientific Divisions and local Branches. Our mission is to “support the work of ASM by prioritizing the scientific focus of the Society and identifying upcoming opportunities in microbial sciences and scientific trends to ensure effective programs and scientific activities that benefit the members and the scientific community at large.” My goals are to increase transparency, broaden engagement and support community-building in our focus areas. I am thrilled to be a “brand ambassador” for ASM and look forward to serving the field of microbiology with a focus on education and outreach.
In the interest of transparency, I’ve posted my original statement of candidacy here as well as my remarks at the COMS meeting during ASM Microbe 2018 in Atlanta. Comments are encouraged.
It is an amazing time to be an evolutionary biologist and microbiologist.
I’m an evangelist for the study of microbial evolution-in-action. I love sharing how powerful experimental evolution can be for understanding how microbes work, particularly when combined with contemporary genomics and bioinformatics. This approach is broadly relevant to all of the disciplines represented by the ASM, from host-microbe interactions, to applied microbiology, to education. At the same time, technology is enabling us, for the first time, to study microbes as individuals as well as members of populations, and identify major transitions in phenotypes as we scale from cell to population to mixed communities.
My laboratory focuses on pathogen evolution that occurs during acute and chronic infections, eco-evolutionary dynamics in biofilms, why genome regions mutate/evolve at different rates, and molecular-genetic mechanisms of bacterial adaptation. Perhaps our most important work has been enabling students to learn evolution and heredity by hands-on experiments with microbes. We are working to distribute this curriculum broadly to high schools around the country.
I was glad to serve on the organizing committee for the ASM Meetings on Experimental Microbial Evolution in 2014 and 2016, and with the end of these meetings want to carry the tremendous enthusiasm from this community forward within the ASM. I’ve been an ASM member since 2000, following Vic DiRita’s advice that it would be the most valuable professional organization I could join. Previously at the University of New Hampshire I was the Chair for the Undergraduate Research Conference, one of the nation’s largest such events. I also supported the local student ASM chapter. Now at the University Pittsburgh School of Medicine, I am Director and co-founder of the Center for Evolutionary Biology and Medicine. I am also Associate Director of the Centers for Medicine and the Microbiome and Innovative Antimicrobial Therapy at the University of Pittsburgh Medical Center.
My vision is to encourage and support education, research, outreach, and scientific-communication activities that allow ASM members to realize the “systems-level” perspectives embodied by the “m-Journals” and apply them to any level of inquiry. We are more than ever in a position to continually ask “why” questions that broaden the relevance of our fields for society as whole, and help us solve some of society’s most pressing challenges.
The motivation: to broaden our community. Many hands make light work!
We are thrilled by a new NSF award “Role of tRNA base modifications in genetic code accuracy and cellular fitness”, in collaboration with Rebecca Alexander of Wake Forest University and Jonathan Minden of Carnegie Mellon University. This project has been a longtime labor of love focused on a peculiar set of mutations that evolved in a screen for beneficial mutations. Remarkably, these mutations point to adaptations leading to mistranslation, and together we will understand how and why. Each lab is seeking a Ph.D student or technician who is interested in learning how natural selection shapes the fidelity of translation, and how cells might monitor homeostasis via tRNAs.
There’s been a fair bit of recent discussion about why most biologists are (uncritically) adaptationists. I don’t dispute this but think it’s worth reconsidering why. Some have argued that this is because of intuition (adaptation just makes sense). However I think a better explanation lies in how we teach - or fail to teach - evolution and acknowledge that teaching non-adaptive evolutionary processes is difficult. Most biologists haven’t had a full course in evolution. Instead, most have had a week or two in their college introductory biology class and if lucky, one week in their high school biology class. If they went to graduate school, they likely had no coursework that explicitly considers evolutionary biology. This is also true for most teachers, so most do not understand evolutionary biology with enough comfort to go beyond well-trodden examples of adaptations to explore with students how and why evolution may not be adaptive. We also must recognize that understanding sources and effects of non-adaptive variation is difficult. It takes a certain depth of education in evolutionary biology to be able to teach non-adaptive processes well. Understanding drift, mutation, and recombination depends more heavily on understanding of statistics and probability, topics that are also generally lacking for most scientists and educators.Another problem is more philosophical, but I think equally important. I wrote the following in my Teaching Statement for my tenure packet several years ago.
“One of Darwin’s most important contributions, many have argued^^1, is that he replaced “typological thinking” with “population thinking.” For typologists, the “wild type” is central to all scientific inquiry; for population thinkers, the “wild type” is an average of many individuals whose variation is the subject of study. Yet this dichotomy still pervades biological education and research. Nearly all of what we are taught in biology begins with a description of discrete characters with certain function: this enzyme performs that reaction, this species lives in that environment. This may be a necessary starting point, but we rarely progress to illustrate that these “facts” are actually average population phenotypes that may not actually exist in any one individual. In my discipline of microbiology it is almost impossible to study single individuals, so the entire field relies on populations usually without recognizing this point. This shortcoming in our curricula likely contributes to how readily we overemphasize differences among individuals and to the widespread doubt of the effectiveness of evolution.”
Here, the relevant point is that if most students believe in an idealized wild-type, then diversity is underestimated and under- appreciated. Appreciating genetic drift is therefore even more remote. If we wish to tackle these problems with biology education, one solution might include developing examples that includes both adaptive and non-adaptive processes. Building in concepts of probability and effects of population size (think conservation genetics) would also be very helpful. Above all, getting teachers to invest more than the standard “one week at the end of the semester” to teach evolution would be a huge victory, one that would benefit all of our education in biology.
The Cooper Lab would like to extend a thank you to Elaine Vitone who wrote a feature, Untangling Darwin, focused on the lab’s research in the University of Pittsburgh’s PITTMED magazine. Vitone’s feature can be accessed on PITTMED’s webpage or as a PDF.
