Implementing Educational Innovations Through
Inquiry-based and Collaborative Experiments

Project Funding Period: January 2007 to December 2009
Project Summary:
This project uses the inclusion of a modern chromatographic method, GC-MS, to
facilitate change the way undergraduate chemistry is taught at Penn State
Altoona. This change includes using real-world applications and inquiry-based
learning laboratory experiments in General, Analytical, Environmental, and
Organic Chemistry Courses. Environmental, forensic, and biomedical themes that
represent realistic situations are being used to engage and motivate students as
well as develop problem solving and critical thinking skills. Collaborative
experiments are being developed that will allow students from Analytical and
Organic Chemistry classes to work together in investigating real-world issues.
In addition, the new GC-MS is being used in undergraduate research and is
planned for use as a part of our well-established community outreach program. A
new program is being developed in cooperation with a local high school chemistry
teacher to bring high school students to the campus for an afternoon in the
laboratories to participate in appropriate inquiry-based experiments with
undergraduate students and faculty. An evaluation plan with both formative and
summative components has been developed to assess the success of the program.
The project is being used to enhance the chemistry education of undergraduate
and high school students who will go on to careers in a variety of fields. The
research, outreach, and collaborative aspects of this project are being used to
benefit women, minorities, and groups who are traditionally under represented in
science. Workshops for STEM faculty, local high schools, and community colleges
well as publications and presentations are planned to disseminate project
results.
Current Project Status: (as
of December 2008)
Project participation and evaluation questionaires,
including assessments of student learning gains,
were developed for the beginning and end of the semester for each of the
involved courses. Upon approval by Penn State’s Office of Research Protections,
student participants were recruited and the questionaires were administered starting with
the Spring 2007 semester.
The new GC-MS, a Varian Saturn 2200, was ordered, and was
received and installed in June 2007. The Savant Learning Center simulation
software for learning GC-MS fundamentals was also ordered and installed.
During the summer of 2007, a new, inquiry-based GC-MS experiment based on an
arson investigation was developed. This experiment was implemented
in Fall 2007 for two sections of General Chemistry I and one section
of General Chemistry II.
Also during the summer of 2007, an undergraduate research project which involved
the analysis of the heterogeneous oxidation of benzyl alcohol to benzaldehyde by
GC-MS.
Work in late 2007 included the development of new GC-MS experiments in the
quantitative analysis and organic chemistry courses, as well as an additional
experiment for general chemistry. These new experiments will be implemented in
Spring 2008.
In the Spring 2008 semester, the implementation of GC-MS experiments was expanded to include a gasoline lab in the second general
chemistry lab, and inquiry-based citrus and banana experiments in analytical and organic chemistry courses, respectively. In addition, a
collaborative mint experiment involving students from analytical and organic chemistry courses was introduced. Also, the arson experiment
introduced in 2007 was modified to make it more inquiry-based, and an additional module (paper chromatography) was added to the lab to improve the students' learning experience.
During the Summer of 2008, improvements were made to the experiments based on student, instructor, and evaluator feedback, and the
evaluation instruments were further modified to improve the value of the information gathered, such as modifying the SALG forms to allow
students to describe specific examples of how they were helped by certain activities. A new inquiry-based environmental lab was developed.
In Fall 2008, the inquiry-based environmental lab was introduced, and implementation of the other new experiments continued.
Implemented Experiments:
CHEM 111 (Experimental Chemistry I): Arson Investigation
