Math & Science Graduate Fellows in K-12 Education

Fellow: Jennifer Olker, Ph.D. graduate fellow in Integrated Biosciences
Teacher: Mayme Walters, East High School, 10-12th grade Biology & Physical Science

I have a BS in Biology and Mathematics from Northland College and a MS in Biology from the University of Minnesota Duluth.   My research interests include wetland ecology and associated communities, especially amphibian ecology; wetland ecosystem and organism responses to local and landscape stressors; impacts of climate change on aquatic habitat and communities.  In fall 2008 I began my PhD program in the Integrated Biosciences program at UMD after several years as a Research Fellow at the Natural Resources Research Institute.  My dissertation research continues my work on the effects of anthropogenic stressors on amphibian populations and expands the scope to include physiological and developmental in addition to organismal and population level responses.  

Through my participation in the GK-12 project I hope to better communicate my scientific research, while also improving my teaching skills and contributing to local K-12 science education.  I believe that improving the scientific and mathematical understanding and appreciation in the non-scientist or budding scientist will lead to more aware and better informed global citizens.

My role is to provide scientific support and excitement to the Biology curriculum.  I have participated primarily in the laboratory exercises, as an additional resource for questions and encouraging students to continue to explore the topic.  I have also brought in several specimen collections for general interest (malformed amphibians) and reference (aquatic macroinvertebrates).  In addition to the time spent in the classroom, I am providing my mentor teacher with real datasets and current research articles for the students to work with.  One of our goals is to incorporate data graphing and interpretation into the current curriculum through exposure to “real” data, hand graphing, and excel exercises.  My presence in the classroom has provided support for lab exercises, especially in the large classes, and offers students another perspective on biology and science.

As part of our year-long effort we conducted an "Action Research Project" to test different strategies and classroom techniques for teaching students a how to make and interpret graphs. To see a summary of our efforts, click here!

I also attended the 2010 Midwest SETAC conference and presented a poster on my GK-12 efforts. Folks were very interested and impressed with the program. To see a copy of my poster, click here!

Curriculum

Comparative Mammal Physiology

Grades 9-12, this lesson uses real data and graph excercises to let students explore differences in physiological characteristics of several mammal species and discuss how these differences can inform science and medicine. To download an Excell spreadsheet used in this lesson, click here; and for a powerpoint supplement (2.6MB), click here.

Introduction to Excel

A lesson developed for 10th grade Honors Biology. An introductory lesson on graphing in Excel using experimental tadpole growth and development data. The attached lesson plan includes an introduction, examples and short graphing activity (Excel or by hand).

Aquatic Invertebrates

A lesson developed for 10th Grade Biology. This lesson provides
macroinvertebrate data from North Shore Streams (collected by the
Natural Resources Research Institute) to use alone or in conjunction
with stream sampling for aquatic macroinvertebrates. The attached
lesson includes background on Biotic Indices, data from 5 streams, and
examples of how to graph this data.

Communicating Science - option 1

A lesson developed for 10th grade Honors Biology. A short introduction to how science is communicated. Students will read recent scientific articles written for the public, answer guided questions (worksheet), and discuss the articles with an instructor. The attached lesson includes a list of 30 articles and the topics each addresses.

Communicating Science - option 2

Students will teach their fellow students about 1 article they read (jigsaw activity) and then create concept maps for 4 articles in small groups. The attached lessons include a list of 45 articles and the topics each addresses.

Action Research Summary

Students have difficulty understanding how to work with data, create or interpret graphs, and use graphing programs such as Microsoft Excel.  These skills are valuable for excelling on the standardized tests and continuing on in the sciences (in secondary school and beyond).

By incorporating real biological data to match the existing biology curriculum, we hope to supplement the information provided through lectures, laboratory activities, and the textbook.  These datasets also provide an additional source of concrete experiences that can provide motivation for learning biology topics

Cell Cycle Duration

A lesson developed to be used in a 10th grade
Biology class to accompany a mitosis lesson. Consists primarily of a
worksheet to follow-up mitosis lesson and to have students practice
interpreting graphs. This is designed to accompany and supplement an
existing lesson on mitosis, not replace it.

Human Nervous System

A lesson developed to provide a comprehensive overview of the nervous system in less than 1 hour for a 10th grade Biology class. Designed to meet the National Academy of Science (NAS) National Science Education Standards recommendations that all students understand the behavior of organisms, including the components and functioning of the nervous system, sense organs, and behavioral responses to the environment. Consists of a game, concept map with lecture, show-and-tell, and several activities that can all be included or modified to meet the needs and timeline of a class.
