Evaluating
Multimedia-Learning Tools Based on Authentic Research Data That Teach Biology
Concepts and Environmental Stewardship
Jacqueline McLaughlin & Daniel A. Arbeider

Abstract
High school science teachers and students need interactive, multimedia research-based learning objects that (a) support standards-based teaching, (b) enforce complex thinking and problem solving, (c) embrace research skills, (d) include appropriate assessments to measure student performance, and (e) show “real-world” uses. To meet these five criteria, the CHANCE modules have been purposefully designed to allow students to “learn how things work” using real-world research data. These modules pace students through images and text that help them to interpret biological and ecological principles. Indeed, each module has been carefully field tested with practicing in-service and preservice science teachers and real students to assure its effectiveness. Notably, the integration of authentic scientific research with sequenced, interactive computer simulations create a solid curriculum base of national interest that has laid the groundwork for additional materials collections that capitalize on the resources of communities that surround schools in particular regions of the country.
NCLB is like a one-size-fits-all dress made
for women who range from a size 4 to a size 2x; the dress looks right on the
woman who wears a size 2x, but when the woman who wears a size 4 or size 8 puts
on that dress, it falls off her shoulders. NCLB and the one-size-fits-all dress
will need to be altered to fit all consumers.
-Mildred L. Taylor, high school biology teacher
(National Education Association, 2007, p. 188)
Most environmental education at the secondary level occurs
inside classroom walls, focusing on textbook content and packaged laboratory
activities with only an occasional outdoor activity. Worse yet – this material
consists of one or two chapters in a general biology book, which may or may not
even be covered in its entirety during a short allotted time period in one
academic year. Moreover, the science underlying this curriculum, in general,
remains watered down as mere vocabulary words with definitions and color-coded
diagrams, graphs, and tables in order to mass produce textbooks and “cookbook”
lab manuals and to meet “the standards.” According to Schmidt, McKnight and Raizen (1997), American science curricula are a “mile wide
and inch deep” for their “jumble of topics” and lack of depth (cited in Beatty,
1997, p. 10). By the time preservice science teachers
come to their supervised field experiences, they face the daunting tasks of
preparing lessons with suboptimal materials and methods. By perpetuating these
deficits, schools are “producing a society with
little scientific literacy at a time when such literacy is needed more than
ever” (Wubbels & Girgus,
1997).
Real science teaching should involve “scientific teaching,”
active learning strategies to engage students in the process of science itself,
and teaching methods that have been systematically tested and shown to reach
diverse students (Handelsman et al., 2004). According to physics Nobelist Carl Wiemen, one of the
best ways for teachers to implement scientific teaching is to bridge the
crucial gap between teaching and basic research. However, in an age where the
costs of complying with unfunded mandates such as the No Child Left Behind Act fall to already overburdened school budgets, in-service
teachers find themselves without resources to create scientific teaching
approaches that will help their students master science content standards,
approaches that they would also want to share with their preservice colleagues.
Reconciling Standards to Classroom Creativity: A National Beginning
According to the authors of the National Science Education Standards (National Research Council,
1996), students need “access to skilled professional teachers, adequate
classroom time, a rich array of learning materials, accommodating work spaces,
and the resources of the communities surrounding their schools.” Although
national, state, and local budget cuts continue to constrain students’ access
to all of these resources, curriculum developers nationwide have been collaborating
with skilled teachers and scientists to create effective, integrated learning
strategies that strengthen teachers’ professional skills, make optimal use of
classroom time, and broaden student access to learning materials via the
Internet.
Guidelines have been proposed by leading national
science education organizations for the integration of technology into science
classrooms and for the preparation of science teachers (Flick & Bell, 2000).
These guidelines include the following:
- Technology should be introduced
in the context of science content.
- Technology should
address worthwhile science with appropriate pedagogy.
- Technology instruction
in science should take advantage of the unique features of technology.
- Technology should make
scientific views more accessible.
- Technology instruction
should develop understanding of the relationship between technology and
science.
Although textbook publishers have produced rich arrays of
highly interactive CD-ROM materials for several decades, they are often priced
outside the reach of many public school district budgets, particularly when
teacher training ancillaries and workshops impose additional fees before the
materials are even useable in the science classroom. Science teachers need more
affordable options for accessing highly interactive science materials. Federal
attempts over the last decade to close the digital divide through an estimated
$3 billion annual e-rate Internet funding (Universal Services Administrative
Company, 2007) and the concurrent “Moore’s Law” (Moore, 2003) of halving prices
while doubling computing power have rendered the Internet a far more accessible
medium for many public school science teachers and students. The project
discussed in this article takes advantage of the increasingly more affordable
Internet to deliver highly interactive science materials.
In response to increased public school access to the
Internet, the Office of Science Education (OSE) at the National Institutes of
Health (NIH) has recently launched a Curriculum Supplement Series of web-based
materials that continues to grow as funding and expertise are allocated to this
project (OSE, 2006). The major advantages of these materials for teachers can
be summarized in four key points:
- Access
to the materials in print or multimedia formats is free via the Internet.
- Practicing
science teachers and NIH scientists co-author the
materials.
- Each
learning module is aligned to national and state science standards.
- Teacher
guides and complete lesson plans are also included at no charge.
The modules already available from
the growing collection at the NIH Web site follow an adaptation of the classic Atkin-Karplus (and later Lawson) model of sequenced
instruction, applying a Piagetian learning cycle. Recent
cognitive research on how people learn and, particularly, on
how children learn science has refined the earlier Piagetian cycles to occur much earlier and more iteratively in young learners’ brains (Bransford, Brown, & Cocking, 1999; Donovan & Bransford, 2005; Duschl, Schweingruber, & Shouse,
2007).
Observing the integration of conceptual frameworks to
existing semantic maps and conceptual frameworks recommended in this updated
work on learning science, the authors of the NIH-sponsored curriculum have
developed a “5E” instructional model that encourages learners to Engage,
Explore, Explain, Extend, and Evaluate (Bybee et al.,
2006). Teacher education programs should have access to these materials via the
Internet, which is increasingly available in schools at lower costs than many
packaged textbook ancillaries. Furthermore, faculty members who design
curriculum for these programs should consider incorporating these resources into
their required curricula.
The interactive environmental science modules created by the
authors of this article have expanded on the NIH 5E model to incorporate the
most current knowledge of how students learn science. Notably, we will show how
we have carefully aligned the four perspectives of learning environments:
learner centered, knowledge centered, assessment centered, and community
centered (Donovan & Bransford, 2005).
Leveraging the low-cost Internet delivery and the
integrative curriculum design model, the multimedia materials were field tested
among preservice and in-service teachers. These
materials are high-quality, richly interactive curricular tools that many
science teachers have said they find useful and intend to use in their
classrooms. The preliminary field test results described in this article have
laid the groundwork for follow-up research that will be underway with a larger
sample of teachers in the near future to determine whether particular groups of
teachers may be predisposed to using Internet-based materials in their
classrooms. This article, however, presents the initial findings among those
current and prospective teachers who have tested the materials.
A CHANCE for Pennsylvania Science Materials
Even as the NIH materials have begun to meet the national
needs for multimedia science education tools integrating authentic research, a
similarly engaging Internet-based project of regional interest to the
mid-Atlantic region of the
United States
has simultaneously been reaching these same consistently high standards by
integrating authentic scientific research from Pennsylvania
communities into sequenced learning materials. Just as the NIH modules have
been co-authored and field tested by science teachers, so too, have the CHANCE modules
begun to be field tested, as this article will demonstrate.
CHANCE (Connecting Humans and Nature Through Conservation Experiences) is a collaborative project between the Pennsylvania
Department of Education (PDE) and Pennsylvania State University (PSU) to (a)
train biology teachers via authentic field work, and (b) develop a
clearinghouse of engaging, standards-based, multimedia science teaching tools
that integrate authentic research and inquiry-based teaching methods. One
important distinction between CHANCE research modules and other materials
currently available on the Internet is that CHANCE materials are authored by
either in-service teachers or preservice Pennsylvania
high school teachers who have participated in the CHANCE course component, Environmental
Science and Conservation Biology: A Field Course in the Biodiversity of Costa
Rica, working in the field alongside
researchers for 3 weeks (McLaughlin, 2006).
Following their return to the
United
States
, preservice and in-service teachers attended an all-day
workshop where they learned to use Web-based interactive multimedia research
modules, freely available at https://teamworks.campuses.psu.edu/psu/lv/chance.
Teachers who wished to design a module of their own then vied for a competitive
opportunity to outline a storyboard (a written description of a module’s page-by-page
content, including text and intricate details of all animations and
activities), the key element of module development. This carefully constructed
professional development course allowed preservice and in-service science teachers to focus on how people learn science: from
learner-centered preconceptions that must be pre-assessed and addressed by the
learning environment to knowledge-centered presentations of materials that must
consist of both a conceptual framework and a set of coherent facts for
learners. The CHANCE participants then learned how to integrate formative
assessment that allows their learners to engage in interactive manipulation of
new knowledge on screen and on paper with those community-based experts in
authentic field research, making CHANCE modules a uniquely balanced curricular
approach (Bransford et al., 1999; Donovan & Bransford, 2005; Duschl et al.,
2007).
Selected teachers were then paired by the director with CHANCE
mentors, research scientists, and/or specialists in the selected field of study,
in order to acquire current and relevant data, expert advice, and guidance pertaining
to their module. All storyboards were edited by the director and, when
finalized, sent to the CHANCE instructional design staff for actual Web
creation and uploading to the Internet. All modules were then extensively
reviewed for scientific content by CHANCE mentors and other research
scientists. Whether selected to author materials or not, after they return from
a CHANCE field experience, preservice biology
teachers in Pennsylvania receive
classroom training in using the modules. Furthermore, all CHANCE modules are
freely available to any preservice biology teacher
via the Internet.
The CHANCE to Improve: Preliminary Field
Tests by Teachers
The interactive multimedia CHANCE
research modules aim to improve environmental literacy and stewardship among
high school students in the state of Pennsylvania and the nation and are one
part of the professional development program, CHANCE (McLaughlin, 2006). These
interactive multimedia research-based modules
support standards-based teaching (Pennsylvania Department of Education, 2002),
enforce complex thinking and problem solving, embrace research skills, include
appropriate assessments to measure student performance, and portray real-world
environmental issues.
The
module, “Invasive Plant Species in Pennsylvania,” was authored by Pennsylvania teacher Melanie Hoskins, William Allen High School, Allentown Pennsylvania. This 8-year veteran teacher worked with Art Grover, Research Associate
for the Roadside Vegetation Management Research Project with the Department of
Horticulture at The Pennsylvania State
University. His research efforts
include management of specific weed species, such as Tree of Heaven, Japanese
knotweed, and Canada thistle; evaluation of alternative plant species for
roadside conservation plantings; and comparisons of equipment, herbicides, and
procedures for managing roadside vegetation. Art is a also a member of the Pennsylvania
Invasive and Noxious Plant Working Group, a past-president of the Mid-Atlantic
Exotic Pest Plant Council, and a member of the Executive Committee of the
Northeastern Weed Science Society.
Sixty-eight teachers (10 preservice and 58 in-service teachers) evaluated this
module using both the cyberguide for Web Site Design,
and the cyberguide for Content Evaluation (MacLachlan, 1996). These two instruments primarily elicit
teacher responses to the content of a Web site. Based on the responses that
follow, we are now planning a follow-up study that will test a hypothesis of
whether and to what extent teacher characteristics correlate to their
evaluation of module content and to their likelihood of classroom adoption. To
gauge the likelihood of adoption in this first study, a subset of 46 teachers
(10 preservice teachers) also completed a brief Implementation
Survey noting their likelihood to use the module in the future. The teachers’ responses to the Invasive Plant Species in Pennsylvania
module served as a feedback mechanism for the module design team. Although
responses to the cyberguide modules were equally
strong among both preservice and in-service teachers,
the preservice teachers were far more likely to
select CHANCE materials for definite future implementation than were the
in-service teachers, a conclusion which suggests some difference between these
populations that will form the basis for a future study. A complete discussion
of the module and accompanying survey results in this first study follows.
Results of the Teachers’ Evaluations to the Invasive Plant Species
Module
In this module students are first asked to observe and read about native plant species of Pennsylvania by viewing a slide show of real images taken throughout
the state. The objective is not only to learn what a native species is but also
to identify ferns and clubmosses; grasses, sedges, rushes, and their kin; annual, biennial, and perennial
wildflowers; woody trees and shrubs; and aquatic plants. They also learn how to
differentiate these groups and common species of each found in natural habitats
of Pennsylvania (see Figure 1).

Figure 1. In the module
“Invasive Plant Species in Pennsylvania,” students examine and read about native plants of Pennsylvania, and how to identify and
differentiate common species. |
Teachers’ responses (n = 68) to the Evaluation of Content
questions about this component were unanimous, as depicted in Table 1. Preservice teachers, in particular, appreciated the
hyperlinked annotations on these introductory pages. Like the glossary in a
textbook, these annotations assist new teachers in presenting concepts holistically,
with a more dynamic pop-up capability for their students to double-check basic
vocabulary. Informal comments from the group provide the basis for a future
study investigating whether differences between these groups impact their
rationale for approving of this content. For example, because a majority of preservice teachers have grown up with the Internet, the
hypertext approach to presenting concepts is familiar and comfortable for them.
For in-service teachers, the unobtrusive option to click on a key term or not
takes only a few practice sessions to master quickly and easily.

The next phase of the module
requires students to observe and read about invasive plant species of Pennsylvania. Using a virtual animated slide projector, which can be navigated with a
click or the simple right or left movement of a mouse, images of common
invasive plants spreading into Pennsylvania's fields, pastures, forests,
wetlands, waterways, and natural areas at an alarming rate are projected as if
sitting in an auditorium (see Figure 2).
 |
| Figure 2. Using a virtual animated slide projector, students observe and read about the negative impacts of invasive
plant species of Pennsylvania. |
Teachers (n = 68)
who responded to the Web Site Design cyberguide noted
the undivided observations about this module displayed in Table 2. Once again,
although the responses to the survey were equally strong, the preservice teachers’ comments indicated that they preferred
the animated slide show with mouse navigation for its interactivity over a
simple textbook explanation. As novice educators, the preservice teachers often struggle with the challenge of adjusting their pace of instruction
to meet a wide variety of learners in their classes. The interactive slide show
allows these new teachers to show students how to navigate forward and backward
to accommodate their own pace as learners.

The module then presents an activity in which students learn
about the structure and hierarchy of organization of an ecosystem by exploring
a native pond/meadow plant community comprised of a diverse arrangement of
native Pennsylvania plant
populations. Then, students are asked to use a virtual field notebook to
calculate and record the population density of selected native species –
Eastern hemlock, red maple, red oak, and winterberry – in a specific area by
doing some simple math (see Figure 3).
One objective is that students
discover how population density is used by ecologists, foresters,
and conservationists as an important field indicator to observe, measure, and
study the negative effects of invasive species on an ecosystem. Low population densities may cause an extinction
vortex, where critically low numbers lead to reduced fertility.
At this point in
the module, the alignment of all four learning environment perspectives is
complete: a learner-centered opportunity for students to gauge what they
already know in their online journals; a knowledge-centered slide show and
pop-up, context-sensitive glossary of terms that establish a coherent
conceptual framework; an assessment-centered problem-based activity that
requires students to apply new knowledge to semantic structures and conceptual
frames; and a community-centered connection to an authentic research project in
the state of Pennsylvania (Bransford et al,, 1999). This careful and
comprehensive alignment of these perspectives makes the CHANCE modules unique
among the curricula currently available to science teachers (see Figure 3).
 |
| Figure 3. Later in the
module, students collect, calculate, record, and analyze data on the population
densities of native species like the Eastern hemlock, winterberry and Indian
grass in a Pennsylvania pond/meadow plant
community—simulated here to help them learn about
this common biological measurement that is often used by ecologists, foresters
and conservationists to predict species survival. |
In response to the design of this
module, teachers (n = 68) were asked
to select each summary statement that appears in Table 3 as a gauge of their
likelihood and intended manner for using the materials in the future.
Notably, the in-service teachers (n =
58) were far more likely than were the preservice teachers (n = 10) to select “worth
bookmarking” rather than “very useful for my information needs,” suggesting some
differences between these populations worth investigating in a follow-up study.

In free response comments collected after the evaluation
workshop, preservice teachers, in particular, noted
that they will be using the CHANCE modules during their student teaching
practicum experiences, indicating that this group will be more likely to adopt
the CHANCE materials in their classrooms in the future; for example,
The modules really are engaging. I
felt an adrenaline rush as a teacher as I worked through the module. All I
could think of was that my students will love this and actually learn something
meaningful about the environment as they use it.
Liked the
animations, pictures, activities, and research scenarios. I can’t wait
to try the other modules.
Importantly, throughout this
module, like all CHANCE modules, students are required to answer increasingly
difficult questions. These lower to higher level thinking questions further their understanding and are the key to
inquiry-based learning. For example, after working through an animation of a
roadside disturbance students learn about the Tree of Heaven (Ailanthus altissima), also known as Ailanthus, an invasive trees
species originally from Asia, which is having a devastating impact on many of
the natural plant communities in Pennsylvania.
Students are asked to make a
hypothesis as to what will happen if one Ailanthus tree seed germinates, takes
root, and is allowed to grow for a period of 10 years in the pond/meadow plant
community they studied in the preceding activity. Thus, students must consider
not only what they now know about the population density and biology (life
cycle) of the native species in this ecosystem, but also the biology of
Ailanthus (life cycle) and the negative influences of invasive species, in
general, to predict and explain how this plant will affect the survival of the
native plant species already in existence (see Figure 4).
 |
| Figure 4. In this
activity, students learn about the invasive plant species, the Tree of Heaven
(Ailanthus altissima). |
When asked about whether the CHANCE module served as a
positive supplement to the textbook instructions, all 46 teachers who completed
the brief Implementation Survey said “Yes,” additionally noting that more of
these modules should be developed for their classrooms (Table 4).

Later in this module, students
actually witness the invasive nature and negative effects of Ailanthus by examining how the given pond/meadow plant
community changes over time after one Ailanthus seed is allowed to
germinate and grow. After clicking on an Ailanthus an animation begins. An
Ailanthus seed is released, which then floats, lands, and germinates in the
pond/meadow community.
Students are again instructed to collect, calculate, record,
and analyze data on the population densities of the
given native plant species – Eastern hemlock, red maple, red oak, and
winterberry – as the meadow changes over 0, 5, and 10 years; however, this time the invasive Ailanthus is also tallied.
Overall, their objective is to learn, by working through simulated experimental
data, ways this invasive plant species can and is negatively affecting
Pennsylvania’s natural ecosystems over time, and the methods presently used for controlling and eliminating this invasive species
(see Figure 5).
 |
| Figure 5. In the
last activity students investigate the effects Ailanthus has on the population
densities of selected native plant species found in the given Pennsylvania pond/meadow plant community. |
Completing the brief Implementation Survey about this
Invasive Plant Species module, science teachers (n = 46) were asked about their inclinations to use the CHANCE
modules in the future. Once again, the preservice teachers unanimously answered that they were “very likely” to use these materials
in their future classrooms, while only 86% of in-service teachers chose the
same response (Table 5). Again, the differences between these two populations
provide the basis for future work to carefully examine teacher characteristics
between these two groups.

Discussion
CHANCE research modules evolved from this bleak reality: On
average, K-12 teachers use computers or engage in lab experiences with their
students less than one time per week for little more than word processing, e-mail,
or game and drill software (Becker, 2000; Singer, Hilton, & Schweingruber, 2005; Smith, Banilower,
McMahon, & Weiss, 2002; Wetzel, 1993). Yet, today’s youth spend an average
of 6 ½ hours a week using various forms of media—about a quarter of that time
juggling more than one form of media at a time. The amount of time spent on
computers has more than doubled over the last 5 years (Kaiser Family
Foundation, 2005). Thus, using digital technology is second nature to the Millennial generation, students born between 1980 and 1994,
and research shows that they prefer video, audio, and interactive media, and
they prefer to learn by doing (Carlson, 2005).
In this field test of CHANCE materials by both veteran
(in-service) and preservice teachers, the newer teachers
showed more interest and likelihood to implement digital technology than their
more experienced counterparts, demonstrating this generational preference. Because
this study was focused on providing content feedback to the module authors, we
collected only anecdotal differences between these groups in the form of their
narrative comments illustrated in the preceding pages. Based on these
preliminary findings, a follow-up study that includes demographic information
and pedagogical inventory data will investigate these differences more
thoroughly.
Complicating matters more are the facts that most students
in high school are not reading their science textbooks, nor understanding the
content (American Association for the Advancement of Science, 2000). Moreover,
most preservice science teachers are taught to teach
technology as a separate component of high school education rather than as a
topic integrated into the curriculum (Willis & Mehlinger,
1996; The Milken Exchange & the International Society for Technology in
Education, 1999; Thomas & Livingston, 2004), while over the past decade
spending on technology in the United States tripled, now totaling more than $6
billion (WestEd Policy Brief, 2002).
Thus, it became obvious to us that a new type of interactive
multimedia learning object needed to be developed for both high school science
teachers and students that supports standards-based teaching, enforces complex
thinking and problem solving, embraces research skills, includes appropriate
assessments to measure student performance, and shows real-world uses. The
CHANCE modules accomplish all of these goals in a way that balances what we
know about how students learn science (Bransford et al.,
1999; Duschl et al., 2007) and delivers these modules
to teachers via the increasingly more affordable and student-favored medium of
the Internet.
The CHANCE research modules take full advantage of the
digital propensity of students and new teachers alike and promote inquiry-based
learning by allowing students to explore, observe, question, hypothesize,
manipulate, analyze, and think critically about real science data and
information from accredited research programs in Pennsylvania
and around the world. Experienced teachers embrace the authentic science that
forms the basis for CHANCE modules and pick up easily on the interactive nature
of the materials. This computer-based interactive approach is particularly
attractive to secondary students, most of whom enjoy the virtual experiences
today’s technology affords. Best of all, CHANCE
modules promote active learning by providing opportunities for students to
participate as individuals directing their own learning process.
Conclusions
The CHANCE modules are purposefully designed to be more
engaging and interactive than a textbook by allowing students to learn how
things work. These modules cover key biological and environmental science
concepts using inquiry-based activities that provide compelling animations,
video, factual information, and research-based exploration that necessitate
students working with real research data. Using the tools of science to teach
science, the goal of these learning objects is to produce levels of
understanding, knowledge retention, and transfer that are greater than those
resulting from traditional lecture/lab classes by blending teaching and basic
research through technology.
Thus, in addition to the likelihood of particular groups of
teachers to use these modules, a point worthy of further consideration is the
actual degree to which these modules exceed text-based instruction. In order to
assess if the use of research modules enhance student learning of core
biological concepts and required Pennsylvania Environmental and Ecological
Standards, a research plan is underway to develop and orchestrate the use of
standardized assessment tools before and after module use in selected
Pennsylvania high school classrooms. Comparisons will be made on similar groups
of students taught the same concepts using a textbook only.
At the core of the CHANCE modules and the larger
professional program they represent is the underpinning objective to enhance
environmental awareness in the
U.S.
high-school student population. Our environment faces serious threats resulting
from human activity – water pollution, air pollution, loss of biodiversity,
depletion of natural resources, and watershed depletion – all of which must be
understood in the context of basic biological principles and solid research.
Thus, in order to help students understand the real world
environmental issues that confront them and become informed citizens, it is
time for teachers to understand by using research how science works, not just
by textbook content. CHANCE’s field component trains
teachers in environmental science, ecology, and conservation practices on an
international, eye-opening level via hands-on field work in Costa
Rica. CHANCE’s research modules equip teachers with technology-enriched pedagogical tools to
provide inquiry-based activities in areas that foster their students’ competencies
in biological concepts and real world environmental issues like climate change,
species extinction, water pollution, loss of wetlands, etc., while at the same
time instilling an inclination toward environmental advocacy.
Thus far, seven modules have been developed and are already
in use in high schools and by educational organizations throughout the
Commonwealth and the world. Completed research
modules include the following topics: invasive plant species in Pennsylvania; raptor migration – local, cooperative, and global;
amphibians as indicators of environmental change; sea turtle nesting behaviors
and survival; deciduous forest biodiversity; species extinction; and water and
air pollution. Modules in the planning stages include topics on global climate
change, watershed restoration, waste disposal, water pollution (treatment
wetlands), and the newest technology in electricity production, burning culm, the main waste product of coal incineration.
The Pennsylvania Department of Education now recommends the
CHANCE field course and research modules as ways of helping high school
teachers and their students meet the nine state standards in environmental
science and ecology. Because most states must meet similar standards, the
CHANCE program provides a viable framework for improving or reforming high school biology education nationwide.
The impact of the CHANCE field course and its modules on
teachers and their students has been overwhelmingly positive. Put simply,
hundreds of teachers from all over Pennsylvania
and the nation are embracing these resources. Free response comments by Pennsylvania
high school teachers after completing the CHANCE field course and module
training included the following:
When I went to
Costa Rica
as part of the CHANCE program, I had just graduated college and was
about to embark on my first year of teaching 8th grade science. Looking back, my experiences doing the field research with
Costa Rica's rich beauty, such as working with nesting sites
for Leatherback Sea Turtles and tagging female Green Sea Turtles who came to
shore to lay eggs, truly molded my teaching philosophy. The wonderment and excitement I felt made me want to recreate that for
my students. If I could evoke these same kinds of emotions and inspiration in
my students, they would learn. Bringing biodiversity and inquiry to my
classroom through the CHANCE program has been the most influential part of my
teaching career. Jennifer Paukovitch,
CHANCE 2004.
CHANCE field course changed my life. Since that experience, I've become
more passionate and enthusiastic about teaching biology. It is incredible how
much I can now impact and influence my students about some serious ecological
issues simply by sharing pictures and stories about my trip to
Costa Rica. Melanie Hoskins, CHANCE 2005.
I am a high school Biology and AP
Environmental Science teacher. The CHANCE program was the BEST professional
development program that I have participated in, in over 20 years of teaching.
The interactive approach to Conservation Biology, integrating research was
invaluable. I learned the importance of providing my high school students with
this skill, and the modules make this task truly possible. In addition, seeing,
feeling, touching, participating in programs in
Costa Rica
was absolutely a life changing experience that I bring to my classroom
every day. Paula Wang, CHANCE 2007.
First, the experience of field work in Costa Rica has helped invigorate
me in the classroom; second, the wealth of experiences, pictures, knowledge and
research picked up during the trip (and in the accompanying assignments) has
provided me with tons of new material for my classroom; and third, the
available modules are helping me integrate interactive technology into my
classes as well as being valuable curricular material in their own right. Rick Bloom, CHANCE
2007.
Free response comments by Pennsylvania
high school teachers collected after participation in a CHANCE “research
module” workshop included the following:
The modules really are engaging. I felt an adrenaline rush as a teacher
as I worked through the module. All I could think of was that my students will
love this and actually learn something meaningful about the environment as they
use it.
Liked the animations, pictures, activities,
and research scenarios. I
can’t wait to try the other modules.
