Rethinking Assessment in
Chemistry
Friday
December 2, 2022, at 1100 Pacific = 1200 Mountain = 100pm Central = 200pm
Eastern
Presenters:
Vicente Talanquer, PhD
University
Distinguished Professor of Chemistry, University of Arizona
Abstract: Assessment in
chemistry typically focuses on students’ ability to reproduce specific
information or problem-solving strategy. We often take a “toolbox” approach
that evaluates whether students can deploy isolated pieces of knowledge or
skills to answer disconnected questions. These assessments fail to elicit
meaningful learning and students’ ability to integrate central ideas in the
discipline, scientific practices, and ways of reasoning to think about
relevant problems or phenomena. Many of these assessment approaches also
lead to inequities in the evaluation of student learning in the classroom
and the laboratory. In this talk, I will illustrate and discuss how we are
re-conceptualizing the assessment of student understanding in our college
general chemistry courses seeking to enrich and diversify the evidence we
collect to characterize student understanding. I will also discuss some of
the challenges we face to build an equitable assessment system.

Presenters:
Reni Joseph, Ph. D. Professor of Chemistry, St. Louis
Community College, St. Louis, MO
Laura M. Wysocki, Ph.D. Associate Professor and Chair of Chemistry, Wabash
College
Abstract: As we prepare
students to be tomorrow’s scientists, there is a natural focus on technical
knowledge, but scientists are also experts involved in addressing
multi-disciplinary socio-scientific issues in
society. Deliberative pedagogy emphasizes this important role
through the facilitated discussion of social issues with a technical
component. We will describe a module in general chemistry about
environmental contaminants that encourages students to listen to diverse
perspectives, recognize underlying values of different approaches to a
problem, weigh tradeoffs, and engage in inclusive decision-making about how
we should address water quality in our society.

The Dragonfly Mercury Project: Assessing Mercury Risk
to Ecosystem Health Across the U.S.
Friday October 21, 2022, at 1100 Pacific = 1200 Mountain
= 100pm Central = 200pm Eastern
Presenters:
Collin Eagles-Smith (Supervisory Research Ecologist, U.S. Geological
Survey)
Colleen Flanagan Pritz (Ecologist, National Park Service
– Air Resources Division)
Abstract: The Dragonfly Mercury Project (DMP) is a
nationwide program that pairs scientific efforts to understand mercury
pollution risks with public engagement and education. Mercury is a toxic
contaminant that threatens human and wildlife health. Dragonfly larvae
serve as indicators of mercury contamination in fish and aquatic food webs.
Since 2009, over 6,000 citizen scientists and community volunteers have
helped collect dragonfly larvae from more than 140 national parks and
protected lands for mercury analysis. The DMP has emerged as a critically
unique study that connects people to parks, promotes scientific literacy,
and provides high-quality data on mercury contamination and risk to
resource managers and policymakers.

What’s in the Water? Screening for Trace Organic
Contaminants in U.S. National Parks
Presenters:
Sarah Elliott, Hydrologist, USGS Upper Midwest Water Science Center
Dave VanderMeulen, Aquatic Ecologist, NPS Great Lakes & Monitoring
Network
Abstract: The
National Park Service’s Inventory and Monitoring Program (NPS I&M)
conducts regular water quality monitoring and biomonitoring as part of its
Vital Signs program to assess current conditions and detect long-term
trends. Baseline data related to the presence of trace organic contaminants
(TrOCs) in national park waters was identified as a gap in the vital signs
program. Therefore, in collaboration with the U.S. Environmental Protection
Agency, NPS I&M and park staff sampled 270 surface water sites across
47 national parks over a 10-yr period to assess the presence and
concentrations of TrOCs. Samples were characterized for up to 400 TrOCs
including waste indicators (comprising a variety of contaminants),
pharmaceuticals, personal care products, and pesticides. A total of 156
TrOCs were detected at least once, but only 4 were detected in ≥20%
of samples. Some TrOCs were present at concentrations that may be harmful
to aquatic biota. Results from this monitoring effort fill important
knowledge gaps and can be used to inform future monitoring efforts within
the parks.

The Chemistry of Glass
Archived materials here
Presenter:
Nate Stephenson, PhD. Scientist Emeritus, U.S. Geological Survey.
Abstract: During
my four decades as a place-based scientist in Sequoia and Kings Canyon
national parks, I’ve watched climate change effects go from distant
abstraction -- which we largely ignored -- to acute threats to the very
resources the parks were formed to protect. Changes have been sudden rather than
gradual, and unexpected rather than anticipated by models or experts. More broadly, rapid environmental
changes are forcing tectonic shifts in the missions of national parks and
other protected areas, and in the research agendas needed to support
them. I offer a
“from-the-trenches” assessment of these extraordinary ongoing changes.

From distant abstraction to urgent reality: Watching climate change reshape an iconic
national park
Archived materials here
Presenter:
Charlene Smith, PhD, Corporate Fellow, Corning Incorporated
Abstract: Glass is
part of our lives. The windows that
protect us from the elements while letting us enjoy natural light; the
smart phone screens that we trust won’t shatter; the optical fiber that
transmits our data; the baking dishes that we use to make dinner; the
screens on our large format TVs – these are all made of glass, engineered
with specific compositions for each particular application. In this talk we’ll discuss glass
composition and what compositions are used for different applications. We’ll also discuss chemical trends of
different glass components and how these trends affect glass properties.

Students' Understandings of Multiple Representations in
Chemistry
Archived materials here
Presenter:
Stacey Lowery Bretz, Ph.D.
Title:
Special Assistant to the Provost for Academic Initiatives, University
Distinguished Professor
Affiliation:
Miami University
Abstract: Learning in
STEM courses requires students to become fluent in the symbolic language of
the particular discipline. Developing expertise, however, requires that
students move beyond manipulating symbols to creating explanations using
particulate models of matter for observations in the laboratory. Failure to
accurately interpret and connect these multiple representations of matter
creates challenges for students when learning. Our research group designs
measurement tools to advance our understanding of how students understand
and interpret representations for a variety of core concepts. Findings
regarding students’ reasoning with multiple representations and the
implications for assessment will be presented using examples from multiple
chemistry courses.

Toxicology for Chemists: Integrating Toxicology
Principles into Higher Education Chemistry Courses
Archived materials here
Presenter:
Nimrat Obhi, PhD
Title:
Program Manager
Affiliation:
Higher Education at Beyond Benign
Abstract:
A current key sustainability challenge is that scientists are not trained
how to address hazards when designing chemical products. Specifically,
chemists lack training in toxicology: what makes a molecule hazardous to
human health and the environment? To address this knowledge gap, Beyond
Benign – a non-profit dedicated to universal green chemistry education –
has designed and released an open-access Toxicology for Chemists
curriculum. The curriculum has been developed by a group of key experts and
contains lectures, supplementary material, and additional resources to
allow educators and current and future scientists to understand and
practice chemistry that is safe and responsible for society. In this talk I
will provide an overview of the curriculum, how the course modules can be
used, and the support that Beyond Benign can provide to educators who want
to implement elements into their courses.

The Effect of Multiple Assessment Opportunities on
Student Achievement in a Large General Chemistry Course
Archived materials here
Presenter: Jill K.
Robinson, PhD
Title:
Teaching Professor
Affiliation:
Department of Chemistry, Indiana University
Abstract:
Mastery-based grading involves assessing student mastery of a defined set
of learning objectives. Students have multiple attempts to demonstrate
understanding of an objective and are not penalized for failing on earlier
attempts. A mastery grading system
was piloted in a small general chemistry course at Indiana University and
resulted in a remarkable increase in student achievement. However, it would be too complicated and
time consuming to implement a similar grading scheme in a very large
class. Instead, multiple assessment
opportunities and collaborative, post assessment exercises were used in a
large general chemistry course with 700 students. The practical implementation of
additional assessments, outcomes of student achievement, and lessons
learned will be discussed.
