NABT 2019 – BEACON Evolution Symposium

In this workshop, we will share strategies for using Data Nuggets in the classroom and introduce one that features microsatellite data for various populations of striped bass. This Data Nugget will give students an opportunity to explore genetic markers and how they can be used to inform the management of an important sport fishery by deciphering which spawning grounds the fish were born in.

The materials from the Data Nugget workshop are as follows:

DataClassroom was created by our good friend, Aaron Reedy, a former high school teacher and evolutionary biologist. He developed them as the digital data-tool that he always wished he had when he was teaching in his Chicago Public School classroom. In addition to exploring the Data Nugget datasets, DataClassroom lets students upload their own data, easily create graphs, and even conduct animated chi-square or t-tests when they are ready to move up to null hypothesis testing. Aaron is willing to demo the full DataClassroom tool for any interested teacher or school. You can directly send questions, feedback, or a request for a demo to Aaron at aaron@dataclassroom.com.

Presenting at the KBS K-12 Partnership Spring Workshop

It was standing room only as Marcia Angle and Liz Schultheis presented Data Nuggets at the Kellogg Biological Station K-12 Partnership Spring Workshop. The theme of the workshop was “Data, Data, Everywhere!” so it was a great fit!

We designed this session for Data Nugget “newbies” and gave a quick background on our activities, paired with a tour through the website. We then went through one of our newest Data Nuggets, “Bringing back the Trumpeter Swan” and all the cool potential extensions that can be done with this activity.

NABT 2018 – BEACON Evolution Symposium

Want to learn more about cutting-edge evolution research? Looking for a way to bring more data into your classroom? If so, come check out the Evolution Symposium: Emerging Research in Evolutionary Biology at this year’s National Association of Biology Teachers Conference! This year’s symposium will begin with a talk by Dr. Caroline Williams, an evolutionary biologist from the University of California, Berkeley, whose lab studies the question, how do variable environments drive the evolution of metabolic physiology in ectotherms? Climate change research historically focused on summer, and winter climate change was considered mostly beneficial due to amelioration of damaging cold. Her research is shifting this paradigm, and illustrating how variation in winter conditions drive responses of terrestrial organisms to climate change. The talk will be followed by a hands-on workshop, led by Nikki Chambers; Dr. Elizabeth Schultheis; and Dr. Melissa Kjelvik, where participants will go through a Data Nugget activity that can be used to help bring this data back to their classrooms.

Finding the Data Nugget You Need by Math and Science Content

Not sure which Data Nugget to use next? With over 60 activities to choose from, sometimes it’s difficult to find time to read though all the descriptions and pick one that will fit your needs. From your feedback we’ve learned that you’d like to search by key science and math content within each activity. In response we created a searchable table on our website (under the “Current Data Nuggets” tab on our homepage) that will hopefully help you find the Data Nuggets that best suit your needs!

This table allows you to pick from the 60+ activities we’ve co-developed with scientists and search by the following criteria:

  • Content readability level (Flesch-Kincaid reading grade)
  • Science concepts / keywords
  • Quantitative concepts / statistics
  • Type of graph used in the activity
  • Type of variable (categorical, continuous)
  • Type of data source (raw, summarized), including a note when the full large data set is available when requested

In addition to this table, we have a few other ways you can search for Data Nuggets on our website. Other criteria you can search for include: activity summary and study location (“View in searchable table”), study area (“View on map”), and by scientist (“Meet the scientists!”). Our next step will be to include links to the key NGSS core ideas and scientific and engineering practices, so be on the lookout for that in the near future!

Living Laboratories: Using islands to track natural selection in wild lizards

This post is by MSU postdocs Melissa Kjelvik and Liz Schultheis, and BEACON education director Louise Mead. See the original article on the BEACON website (reproduced below):

The National Association of Biology Teachers (NABT) annual Professional Development Conference provides biology educators from across the nation the opportunity to join other leaders in biology and life science education for four days of renowned speakers, hands-on workshops, informative sessions, and special events. In November 2017 the BEACON Center partnered with the American Society of Naturalists to sponsor a special symposium highlighting cutting edge evolutionary research and introducing attendees to a new study system, research questions, and related resources they could incorporate into their classrooms.

This year’s Evolution Symposium: Emerging Research in Evolutionary Biology at NABT featured a research talk by Dr. Robert Cox (Bob) on selection and fitness in anole lizards, followed by a Data Nugget activity highlighting data from his research. Bob, an evolutionary biologist from the University of Virginia, studies these charismatic lizards, native to Cuba and the Bahamas. He describes anoles as “ecological popcorn” because they are so abundant and are eaten by many organisms. In Florida, where the anoles are invasive, you can shake a bush and 10 will fall out! Bob shared an amazing talk describing his lab’s research on brown anoles and the challenges and opportunities of studying natural selection in the wild. Bob uses real-time studies of wild animal populations to understand the ecological basis of natural selection as it happens. He chose to work with anoles because they are ideal organisms for studies of natural selection; they are abundant, easy to catch, and have short lifespans.

When Charles Darwin talked about the “struggle for existence” he was making the observation that many individuals in the wild don’t survive long enough to reach adulthood. Many die before they have the chance to reproduce and pass on their genes to the next generation. Darwin also noted that in every species there is variation in physical traits such as size, color, and shape. Is it simply that those who survive to reproduce are lucky, or do these traits affect which individuals have a greater or lesser chance of surviving? While evolutionary biology is often viewed as a historical science, exploring processes that have played out over millions of years, Bob stressed that natural selection, the primary force of adaptive evolution, is happening all the time and can be measured in natural populations! Along with field studies, Bob and his lab use genetic methods to help them track the reproductive success of thousands of individuals across multiple generations. Experimental manipulations of predators and competitors also help in understanding the ecological basis of natural selection.

The talk was followed by a hands-on workshop, led by Aaron Reedy, Elizabeth Schultheis, and Melissa Kjelvik, where participants worked together as students on two Data Nugget activities. This open time gives teachers the opportunity to have discussions about connections to educational standards or pedagogical strategies that are helpful for them to translate the research and associated data back to their classroom settings. Data Nuggets (http://datanuggets.org) are free classroom activities, designed to improve the scientific and quantitative abilities of K-16 students by providing them with authentic data collected by practicing scientists. The research in Data Nuggets on the anole lizards focused on two traits – their size, and their dewlaps. The Data Nuggets take students through the process of exploring two different hypotheses.  In Part I students calculate and graph %survival of lizards according to their size at the beginning of the season, to explore the hypothesis that size influences survival and overall fitness.  In Part II, students graph % survival as a function of dewlap size. The dewlap is an extendable red and yellow flap of skin on their throat. To communicate with other brown anoles, they extend their dewlap and move their head and body. Males have particularly large dewlaps, which they often display in territorial defense against other males and during courtship with females. Females have much smaller dewlaps and use them less often. This trait comes with a trade off – while it attracts the desired attention of females, it also attracts predators. There could be sexual selection favoring this trait, while natural selection works against it.

In these and other Data Nugget activities, students read background information on a study system and scientist, graph and interpret authentic data from their research, and use their graphs to construct explanations based on sound reasoning and evidence. By relying on authentic research and data, Data Nuggets’ innovative approach reveals to students how the process of science really works, while building their quantitative abilities and interest in science. One teacher from the workshop shared that, “the beauty of the activity is in the simplicity,” which is a great testament to Bob and Aaron’s ability to take complex evolution research and distill it down to a core message. The Data Nuggets include the story behind Aaron and Bob’s research to further engage students in the journey taken by the scientist as they formulated their research questions and ideas.

Data Nuggets: Inspired by teachers, created using authentic research data

This post is by Data Nugget researchers Liz Schultheis and Melissa Kjelvik. See the original article on the MSTA Newsletter website (reproduced below):

Back when we were biology graduate students, we were first exposed to science education through the GK-12 program at the Kellogg Biological Station. We were each assigned a partner teacher who would mentor us as we taught lessons and shared our research with students for the first time. The experience of standing up in front of 30 middle school students was definitely intimidating! Initially we struggled to simplify and explain our research, while also making it engaging for an audience who may never have thought about these ideas before. However we quickly improved as the teachers stood in the back of the classroom and waved their arms when students checked out because we’d used too much jargon or started to nerd-out. They pushed us to describe why the things we were doing day-to-day mattered for the big picture. The teachers’ infectious enthusiasm boosted the passion we had for our research. Working with these teachers and their students quickly became our favorite time of the week.

These same teachers shared that their students were struggling when faced with data from classroom inquiry projects that turned out messy or did not follow predictions. Typically, students are only exposed to research and data published in textbooks, leading to the misconception that all science is a completed product with well established ideas and clear results. As graduate students we had access to tons of messy data from our own dissertations, and we felt by sharing our research stories we might be able to help students realize that when doing “real science” things are bound to be unexpected and unclear. Over time, we developed Data Nuggets from these ideas. Data Nuggets are classroom activities that bring students through the entire process of science, sharing the story of the scientist behind the data and an authentic dataset from their work. Students are challenged to graph and interpret the data, determining whether the data supports the scientist’s hypothesis or what future research would be necessary to fully answer their questions. Data Nuggets are also a way for us to share what we learned as GK-12 fellows with other scientists, as we guide them through the process of creating a Data Nugget of their own.

This past summer we were lucky to work with some of these same teachers again. As a group we read through student responses to Data Nuggets. This was a powerful way to identify areas we could improve to encourage deep student thinking and rich classroom discussions. While reading student responses, the teachers collectively noticed that students had a difficult time using evidence to support their claims, so they developed a tool to scaffold students into this process. To learn more about Data Nuggets and the tool they developed, make sure to come to our MSTA workshop Data Nuggets: Scaffolding claim-evidence-reasoning using real data in context.

As we continue to develop Data Nuggets, we are exploring the challenges and opportunities created when using real data in the classroom. Today we have 54 Data Nuggets (and counting) on our website, freely available and used by thousands of teachers and students. We are currently funded on a National Science Foundation Discovery Research pre-K-12 grant. The main objective of the collaborative grant, between MSU and Biological Science Curriculum Study (BSCS), is to assess whether Data Nuggets increase students’ quantitative reasoning abilities, along with their understanding of, and engagement with, science.

The color polymorphism in bluefin killifish – males display anal fins in blue, red, or yellow.

Why so blue? The determinants of color pattern in killifish

For more information on the NABT 2016 conference, check out their website, here.

Why be blue in a swamp? The evolution of color patterns and color vision in killifish

Animal communication happens when one organism emits a signal, which then travels through the environment and is detected by the sensory system of another. The environment in which signaling occurs can dramatically alter signal transmission and result in selection where different signals are favored in different environments. The bluefin killifish provide a compelling example. Some populations are found in crystal clear springs (where UV and blue light are highly abundant) and others are found in tannin-stained swamps (where UV/blue light is depauperate). Paradoxically, males with blue color patterns are abundant in swamps and are rare in springs. The resolution to this paradox requires a consideration of how genetics and the environment influence trait expression, as well as the direction of natural and sexual selection in different habitat types, and the manner in which animals with different visual systems perceive the same color pattern.

Data Nugget Workshop: Why so blue? The determinants of color pattern in killifish

Data Nuggets are hands-on activities designed to improve the scientific and quantitative skills of students by having them graph and interpret scientific data gathered by practicing scientists. This workshop will provide an overview of Data Nuggets and present a Data Nugget featuring data on the genetic and environmental basis of color pattern expression in killifish. This Data Nugget will allow students to determine whether color pattern expression is due to ‘nature’ (e.g., genetics), ‘nurture’ (e.g. environment), or the interaction of the two.
