The History And Impact Of A College‐Level Field‐Based Course On Learner And Community Development, David M. Harwood, Leilani Arthurs Nov 2012

The History And Impact Of A College‐Level Field‐Based Course On Learner And Community Development, David M. Harwood, Leilani Arthurs

DBER Speaker Series

Providing students with inquiry‐based learning experiences was a key recommendation made in the National Academies' 2007 report, Rising Above the Gathering Storm: Energizing and Employing America for a Brighter Economic Future, and this presentation is about a model for providing such experiences to college‐level students through a field‐based geology course. GEOL 160 – Fundamentals of Geosciences in the Field was developed 10 years ago for undergraduate students preparing to be K‐12 science teachers. The goals of the course are to enhance undergraduate pre‐service science teachers’ (i) knowledge of geoscience and the nature of science, (ii) attitudes ...


Nanoscience Outreach, Stephen Ducharme Nov 2012

Nanoscience Outreach, Stephen Ducharme

DBER Speaker Series

Informal science education is an important and rewarding activity for scientist and scientists‐in‐training. We are fortunate at the University of Nebraska to have over 90 of faculty research group working with materials and nanoscience, and involving hundreds of students, post‐docs, and visitors. Some of us have banded together to develop an extensive nanoscience outreach effort that reaches nearly every corner of our community, with activities in a wide range of venues – in the schools, at the mall, at summer camps, with civic groups, at Science Cafés, at the Big Red Road Show, and many others – wherever you ...


Insects As Teaching Tools, Doug Golick Nov 2012

Insects As Teaching Tools, Doug Golick

DBER Speaker Series

In this talk I will present on projects in which insects were used as instructional tools. This presentation will give an overview of how insects can be used for teaching with a variety of student age groups and how inquiry instruction can be promoted with insects. I will present overviews of 3 projects including Bumble Boosters, Bugs in the Classroom, and Web‐based insects identification tools. Bumble Boosters created a community of researchers that studied bumble distribution and abundance and artificial nesting domicile preferences. Forty Nebraska high schools were involved in this project.

Bumble Boosters’ teaching objectives were to raise ...


The National Academy Of Sciences Workshop On Assessments In Science Courses, Leilani Arthurs Oct 2012

The National Academy Of Sciences Workshop On Assessments In Science Courses, Leilani Arthurs

DBER Speaker Series

The Next Generation Science Standards (NGSS), which have undergone the first stage of public review and are currently under development, address not only content knowledge but also scientific skills. As such, the National Academy of Sciences (NAS) Committee on Developing Assessments of Science Proficiency in K‐12 envisions the NGSS motivating change in the way that science is taught in the United States. A critical part of science instruction as it is envisioned with the NGSS involves using assessments. This DBER presentation will report on the latest NAS views regarding science proficiency assessments, as they were shared at all‐day ...


Young Children’S Understanding Of Conservation Concepts, Julia C. Torquati Sep 2012

Young Children’S Understanding Of Conservation Concepts, Julia C. Torquati

DBER Speaker Series

This presentation will summarize an investigation of young children’s conservation knowledge and reasoning. Eighty‐two preschool aged children (3‐5 years) were interviewed at two points in time six months apart using a semi‐structured interview. The interview protocol developed by Peter Kahn (2001) was used to assess children’s conservation attitudes. This was the first time the interview was used with preschool aged children. Children were asked questions about the importance of animals, plants, parks, and gardens, and whether it is acceptable to litter (and why or why not). Fifty‐seven of the children attended a preschool located ...

Concept Inventory Design For Determining Students’ Conceptual Understanding Of Oceanography, Leilani Arthurs Jan 2012

Concept Inventory Design For Determining Students’ Conceptual Understanding Of Oceanography, Leilani Arthurs

DBER Speaker Series

Concept inventories are relatively new types of diagnostic instruments intended to measure student learning. Concept inventories exist for astronomy, biology, chemistry, engineering, fluid mechanics, geology, and physics. None is yet available for oceanography, and development of the Introductory Oceanography Concept Inventory Survey (IO‐CIS) serves to fill this gap. A context‐driven development strategy was designed to create this instrument. Qualitative methods utilizing grounded theory and classical test theory were used to construct it. Quantitative methods, including statistical methods associated with classical test theory and item response theory, were used to evaluate and further refine the IO‐CIS. The instrument ...
