As
an applicant for a NCSTA Innovative Curriculum Grant two years ago,
I took the title of the grant literally. If I could receive financial
support for an innovative curriculum or approach, what would I choose?
Could I try some novel teaching methods that I may not have used in
my “traditional” classes such as Freshman Biology and Advanced
(AP level) Biology?
Fortunately,
it did not take long to settle on the idea of a North Carolina Environmental
Science course. While my students are aware of many global environmental
issues (e.g., ozone depletion and global warming) taught in traditional
environmental or earth science courses, they usually have little idea
of the number and types of environmental challenges facing our own state.
In a state where we have “ozone action days,” an expanding
population, shrinking natural wetlands, sewage treatment issues, and
the hog farming controversy among others, I felt it was important to
turn our attention a little closer to home. Unfortunately, I found little
in the way of existing educational materials for this approach.
Upon
receiving the NCSTA grant, I designed a one trimester elective offering
for our juniors and seniors who would not necessarily opt for Advanced
Placement science course here at Cary Academy. The course featured authentic
research on an area of our campus, was project-based (no tests), and
utilized current, up-to-date information (i.e., no textbook). The grant
helped me purchase materials primarily for the research component, including
GPS units, a dissolved oxygen meter, worm composting kits, North Carolina
maps, NPK test kits, and other such materials.
The
course that I developed included an introductory component on environmentalism,
how environmental scientists investigate the environment and basic ecological
concepts. Students then began to research, primarily online, North Carolina
environmental problems and challenges. Among the issues they identified:
threats to wetland and coastal resources, pesticide use, eutrophication,
urban and suburban sprawl, water pollution, erosion, invasive species,
air quality, and Pfiesteria. We then used risk analysis to rank the
issues and considered what impact North Carolina’s growing population
would have on each of these areas of concern.
Water
emerged as an unifying environmental area from our discussions. Students
performed stream sampling of a local creek, examined hog farming for
its water impacts, including a visit to a hog farming operation, and
visited a nearby sewage treatment plant. We also conducted an experiment
on eutrophication and algae growth in the lab, examined the potential
impacts of leaking underground storage tanks (USTs) by using state data
of leaking USTs on-line, considered the causes of erosion, and examined
the prevention of catastrophic effects of hurricanes. By using resources
such as state databases and websites on either side of the hog farming
debate, the course certainly seemed more topical and contemporary than
traditional classes.
A
significant portion of the course was devoted to an authentic environmental
project. We are fortunate to have on our campus a small tract of undeveloped
wooded land (about 3 acres) designated as a “preserved area.”.
The class undertook a study of the preserved area to identify current
and future uses of this tract, environmental concerns (e.g., erosion,
soil quality, and invasive species), the potential placement of a campus
composting site, possible expansion of this tract, wildlife and plant
surveys, the potential for a nature trail, and present and future human
impacts. The three-week study culminated in a presentation by the class
to the school’s Grounds Committee, which readily accepted their
recommendations. Parts of the plan such as expansion of the area, and
spreading wood chips for soil reconditioning have already been implemented.
Subsequent classes will continue to execute the plans of this initial
class and re-evaluate the proposal.
The
final element of the course required students to identify a North Carolina
environmental issue and present the complete picture to their classmates.
As part of this presentation, they were required to generate a “teaching
lesson” including background resources for teachers and a hands-on
teaching demonstration. While the quality of these presentations and
demonstrations was somewhat lacking, I felt it was important for students
in this class to be able to teach about the North Carolina environment
as well. Some felt the teaching of their classmates was the most challenging
part of the course!
At
the conclusion of the course, students were asked to evaluate this class
and if their interest in environmental science was greater now than
when they enrolled. In the initial interest survey of the class, the
class average was 5.2 (on a scale of 0 - no interest to 10 - highly
interested in environmental issues). At the conclusion of the class,
the class average was 8.0, and 85% of the class rated the project-based,
topic-driven approach of this class as good or excellent. Among the
comments I received: “this was the most ‘real’ course
I have ever had,” “the hog farm trip was my highlight! It
wasn’t anything like I thought it would be” and “it
was challenging to put everything we learned into practice with the
preserved area study…the environment seems so simple to study
but it really isn’t.”
While
this approach may not work for everyone, I was gratified to see this
type of project-based, student driven, and North Carolina focused environmental
course succeed. I do not expect the course I taught with this grant
to be replicated exactly by other institutions. However, I think the
deliberate inclusion of any local or state environmental concerns into
existing environmental curricula is terribly important. I also believe
students have to be engaged in as much as authentic environmental research
as practical. I am developing a website for that will have more information
about this project on it: http://web1.caryacademy.org/classes/biology/nces/
I would be happy to answer any inquires about this class. Apply for
a NCSTA grant!
