Parentage Analysis And Conservation Genetics Educational Material For The Eastern Hellbender Salamander, Cryptobranchus Alleganiensis Alleganiensis, Sarah A. Chudyk
Parentage Analysis And Conservation Genetics Educational Material For The Eastern Hellbender Salamander, Cryptobranchus Alleganiensis Alleganiensis, Sarah A. Chudyk
Master's Projects
Populations of the Eastern hellbender salamander, Cryptobranchus alleganiensis alleganiensis, are declining, making this a species of special concern in New York State and under consideration for Federal Endangered Species listing. As a result of this decline, the New York State Department of Environmental Conservation and the Buffalo Zoo initiated a headstarting program with an egg mass found in the Allegheny River drainage. The juveniles being raised by the Zoo will be released back into the watershed and so understanding the genetic diversity and parentage of these hellbenders will inform the reintroduction efforts. Furthermore, in order to determine how to …
Measuring Knowledge Of Natural Selection: A Comparison Of The C.I.N.S., An Open-Response Instrument, And An Oral Interview, Ross Nehm, Irvin Sam Schonfeld
Measuring Knowledge Of Natural Selection: A Comparison Of The C.I.N.S., An Open-Response Instrument, And An Oral Interview, Ross Nehm, Irvin Sam Schonfeld
Publications and Research
Growing recognition of the central importance of fostering an in-depth understanding of natural selection has, surprisingly, failed to stimulate work on the development and rigorous evaluation of instruments that measure knowledge of it. We used three different methodological tools, the Conceptual Inventory of Natural Selection (CINS), a modified version of Bishop and Anderson's (Bishop and Anderson [1990] Journal of Research in Science Teaching 27: 415-427) open-response test that we call the Open Response Instrument (ORI), and an oral interview derived from both instruments, to measure biology majors' understanding of and alternative conceptions about natural selection. We explored how these instruments …
Does Increasing Biology Teacher Knowledge Of Evolution And The Nature Of Science Lead To Greater Advocacy For The Teaching Of Evolution In Schools?, Ross Nehm, Irvin Sam Schonfeld
Does Increasing Biology Teacher Knowledge Of Evolution And The Nature Of Science Lead To Greater Advocacy For The Teaching Of Evolution In Schools?, Ross Nehm, Irvin Sam Schonfeld
Publications and Research
This study investigated whether or not an increase in secondary science teacher knowledge about evolution and the nature of science gained from completing a graduate-level evolution course was associated with greater preference for the teaching of evolution in schools. Forty-four precertified secondary biology teachers participated in a 14-week intervention designed to address documented misconceptions identified by a precourse instrument. The course produced statistically significant gains in teacher knowledge of evolution and the nature of science and a significant decrease in misconceptions about evolution and natural selection. Nevertheless, teachers' postcourse preference positions remained unchanged; the majority of science teachers still preferred …
