Linking
Invasive Species to the Connecticut Science Frameworks
The section
below describes the state of Connecticut's efforts to establish
state science education standards or frameworks. This is not
a unique event, but rather has occurred throughout the country.
The section below only serves as an example of linking the
authentic science planned for the invasive species survey
to some of the CT Frameworks, and is not meant to be inclusive.
The
Connecticut Core Science Curriculum Framework
The Connecticut
State Department of Education worked with educators, school
administrators, universities and industry to craft a vision
of science education in the State of Connecticut for the 21st
Century. The goals were to promote science literacy and motivate
students to pursue careers in STEM (Science, Technology, Engineering
and Mathematics). The process culminated in the release of
the "Core Science Curriculum Framework" in October,
2004 that defines the main conceptual themes and content standards
that students are expected to learn in their elementary, middle
and high school science classes. The roles of the science
framework were defined as: 1) to articulate the core science
ideas, knowledge and skills that all Connecticut students
should learn, 2) to define the knowledge, abilities and understandings
that students are expected to demonstrate on the statewide
science assessments and 3) to influence the way science is
taught and assessed. The document also describes the specific
performance metrics that will be assessed on the statewide
science assessments.
The document
defines scientific literacy as:
"Scientific
literacy requires the ability to apply critical thinking skills
when dealing with science-related issues. The framework was
designed to target the age-appropriate critical thinking -
or inquiry - skills that should be infused in the learning
of each of the content standards. Further, in limiting the
number of content standards required to be taught, the framework
allows for the implementation of a hands-on/minds-on science
program in which students and teachers have time for in-depth
explorations that build an understanding of the way in which
scientific knowledge is created, validated and communicated."
Core Science Curriculum Framework, CT SDE, 2004
Authentic
Science
From the
statement above, it is clear the framers recognized the importance
of inquiry as well as the importance of a hands-on approach
to learning. These elements, translate into problem based
learning within an authentic learning environment. The educational
research literature supporting this approach is plentiful
(Kardash and Wallace, 2001; Brown et al. 1989; Brown &
King, 2000)
In fact the subheading of the Frameworks document is: "An
invitation for Students and Teachers to Explore Science and
Its Role in Society" indicating the focus upon real-world
applications of science to address societal need. The CT SDE
further recognizes the following precepts: 1) science learning
in a context of real world issues and technologies, 2) science
learning that is interesting & relevant to students, 3)
science learning that is an active and thoughtful exploration
of questions and problems.
The challenge
facing educators is how to meet the goals of the Frameworks
within the context of authentic science activities. Fortunately,
at the same time, scientists are being asked to recognize,
develop and promote a "broader impact" of their
science. This has become known as "Criteria Two"
in the review process of the National Science Foundation,
which is a clear indication of the significance that the agency
places on achieving this goal. One solution to meet the expectations
of teachers and the needs of scientists, therefore, is to
promote meaningful teacher/researcher interactions within
the context of the Frameworks. This is what the real-time
Webcast and percent cover learning activity are intended to
do.
The
Relevant CT Frameworks
Below
are two examples of the Connecticut Science Framework Content
Standards and Expected Performances from middle school and
high school grade levels, the first number of the Content
Standard indicates the grade level.

Matter
and Energy in Ecosystems - How do matter and energy
flow through ecosystems?
6.2
- An ecosystem is composed of all the populations that
are living in a certain space and the physical factors
with which they interact.
"
Populations in ecosystems are affected by biotic factors,
such as other populations, and abiotic factors, such
as soil and water supply.
"
Populations in ecosystems can be categorized as producers,
consumers and decomposers of organic matter.

C
1. Describe how abiotic factors, such as temperature,
water and sunlight, affect the ability of plants to
create their own food through photosynthesis.
C
2. Explain how populations are affected by predator-prey
relationships.
C
3. Describe common food webs in different Connecticut
ecosystems.

Heredity
and Evolution - What processes are responsible for life's
unity and diversity?
10.5
- Evolution and biodiversity are the result of genetic
changes that occur over time in constantly changing
environments.
"
Mutations and recombination of genes create genetic
variability in populations.
"
Changes in the environment may result in the selection
of organisms that are better able to survive and reproduce.
|
D
1. Explain how the processes of genetic mutation
and natural selection are related to the evolution of
species.
D
2. Explain how the current theory of evolution provides
a scientific explanation for fossil records of ancient
life forms.
D
3. Describe how structural and behavioral adaptations
increase the chances for organisms to survive in their
environments.
