Physics
Recent research data provide evidence of a
strong focus on the development and fostering of
Math and English skills at the elementary level.
Unfortunately, other areas of study have not
received necessary attention (Goodstein, 2001). At
the University of Florida, the School of Teaching
and Learning teamed with the College of Liberal
Arts and Sciences to address this situation. With
the assistance of a PT3 grant, Dr. Gene Dunnam,
Physics professor, and Richard Hartshorne, Teaching
and Technology Fellow, have designed a course
entitled Our
Physical World: Science for Elementary
Teachers. The course discusses basic
physical science for elementary teachers,
emphasizing applications from everyday life. The
scope of the course is similar to many
college-level science courses. However, while most
courses focus solely on the acquisition of science
content knowledge, Our Physical World also
focuses on the acquisition of pedagogical content
knowledge in science (Duggan-Haas, Enfield, &
Ashman, 2000). Topics addressed in the course begin
with the scientific method and span the entire
spectrum of the physical sciences, even discussing
Einstein and relativity. The purpose of this course
is twofold. First, the course provides
tomorrows teachers with appropriate science
content knowledge. Second, the course models
appropriate methods of integrating meaningful
science learning into the elementary classroom.
In order to attain these goals, Our Physical
World was designed and created as a web-based
learning environment. There were three major
reasons for creating this environment. The first
reason was accessibility of the information. While
initially intended for students of the course, we
thought that the information presented, both in the
course and on the website, might be useful to other
elementary teachers. The second reason was
adaptability. With a web-based learning
environment, activities and information can easily
be updated and modified. The final reason was ease
of communication. On the website, individuals will
be able to suggest activities that they have found
useful, and provide feedback to the creators of the
website.
There are four major components to the website:
a course information area, a relational database, a
Sunshine State Standards search mechanism, and an
administrative area. The first component of the
course is the Course Information. This
area contains important information for students
enrolled in Our Physical World. Items such
as scheduled events, syllabus information,
readings, assignments, and experiments are listed
here.
A second major component of the course is the
relational database known as the PT3
Physical Science Database. Upon entering the
learning environment, teachers are provided with
various activities designed to promote meaningful
science learning. This database is part of the
course website, but potentially could be accessed
by elementary teachers elsewhere. Eventually, the
database might be expanded to cover other science
areas, such as the biological and chemical
sciences. The premise of the database is that
elementary teachers can search for activities by
choosing various criteria. The search criteria
include the following: topic, grade level, activity
type, amount of materials necessary, and Sunshine
State Standards (Brogan, 1995). Any, or all, of the
search criteria may be used when searching for
various activities. The search areas of topic and
grade level, while general, are useful in narrowing
down any search for activities. Activity types will
include simulations, laboratory experiments,
web-quests, tutorial, classroom demonstrations, and
others. One of the more interesting areas of search
criteria is the amount of materials
necessary. Upon leaving elementary education
programs, students go to different schools, with
each of the schools possessing different resources.
The amount of materials necessary field
is broken down into four levels, addressing the
varying level of resources. Theses levels are low,
medium, high, and computer based. While each of
these levels is relative, simply examining a few of
the activities for each of the levels would make
the criteria for each very clear.
A third component is the Sunshine State
Standards search mechanism. This search option was
added, after the initial conception of the
database, in order to assist Florida teachers
relate science instruction to the appropriate
standards. This tool allows students to search
content by the Sunshine State Standards. Sunshine
State Standards as a search criterion will
obviously be of most utility to Florida
teachers.
The final element of the website is an
administrative area. In this area, administrators
are able to add, delete, or modify any of the
activities or search criteria. Throughout the
course, students find appropiate activities on
various physical science topics for inclusion into
the database. Also, there is an area for
individuals using the site to suggest activities by
completing information about the suggested activity
on a form. These activities are then reviewed by
the main site administrator, and, based on quality,
either added or not.
With further development we hope that this
database will prove to be a valuable science
instruction resource for teachers everywhere. While
only students registered for the course will be
able to view the modeling of various activities, it
is the opinion of the creators that the database as
a stand-alone resource would be extremely useful.
As mentioned previously, the database may
eventually stand on its own, outside of Our
Physical World, and may be expanded to contain
other areas of the sciences, and possibly videos of
the course activities being modeled. With these
additions, the goal of improving the instruction of
all sciences at the elementary level may be
attained.
During the third year, there were changes in
both the curriculum and the implementation of
educational technology in Our
Physical World: Physical Science for Elementary
Teachers. The Powerful Ideas In Physical
Science (PIPS) curriculum was combined with past
curriculum in an effort to create more of a
"hands-on" and "discovery learning" atmosphere in
the classroom. The course implemented a small
group/laboratory format and served as a model for
appropriate science instruction at the elementary
level. The PIPS curriculum focused on students
developing their own understanding of basic
physical science concepts likely to be addressed in
the elementary classroom. Topics addressed using
the PIPS curriculum included Light and Color,
Electricity, and the Nature of Matter. Other
topics in the course included Measurement, Motion,
Energy, and the Nature of Science.
The integration of the Personal
Response System (PRS) began during the second
year of Our Physical World and has played a more
prominent role as the course has modified. The PRS
is a remote-controlled method of soliciting student
responses from a variety of prompts. The PRS is
used as a tool for clarifying student understanding
of course material and appropriately addressing
misconceptions. Questions may be asked either
prior to, during, or after a class activity,
followed by an appropriate instructor response to
the student reactions. The Hyper-Interactive
Teaching Technology (H-ITT) software allows for
immediate collection of student responses, allows
for instant checking of results/understanding,
produces a record of student responses which can be
examined in more detail after an individual class
session, provides a graphical representation of the
class responses for immediate examination, and
promotes active student engagement in class
discussions.
The use of Elementary
Level Lessons In Physical Science
(E.L.L.I.P.S.) in Our Physical World has undergone
significant changes since it's first integration
into the course. Initially called the PT3 Physical
Science Activity Database, this tool was used as a
lesson plan resource and collection device for
student-created elementary science lessons. As the
course and tool changed, so did the manner in which
it was implemented in Our Physical World.
Originally, students created elementary physical
science lessons to be added to the PT3 Physical
Science Activity Database. However, we soon
noticed that, at this stage in their programs,
students often did not possess the necessary skills
and knowledge to create exemplary elementary
science lessons. As a result, students are now
required to find exemplary science lessons and
teacher content resources for addition to the
E.L.L.I.P.S. tool. We have found that the students
enrolled in Our Physical World are much more
equipped to successfully and effectively accomplish
these tasks.
Two other recent additions to the E.L.L.I.P.S.
tool include a "discussion board" and a "read/write
lesson review section". Due to the fact that these
tools are early in their development, they have not
been integrated into Our Physical World. However,
there are plans to utilize these tools in future
versions of the course.
