We All Teach The Nature Of Science - Whether Accurately Or Not, Michael P. Clough Jan 2008

We All Teach The Nature Of Science - Whether Accurately Or Not, Michael P. Clough

Iowa Science Teachers Journal

The phrase “nature of science” (NOS) is often used in referring to issues such as what science is, how it works, the assumptions underlying the doing of science, how scientists operate as a social group and how society itself both influences and reacts to scientific endeavors. These and many other thoughts regarding the NOS are informed by contributions from several disciplines including, but not limited to, the history, philosophy, sociology, and psychology of science.


Aerobic And Anaerobic Respiration: Inquiry Compared To Traditional Pedagogical Approaches, Sarah A. Sanderson, Tanya Gupta, Kimberly A. Penning Jan 2008

Aerobic And Anaerobic Respiration: Inquiry Compared To Traditional Pedagogical Approaches, Sarah A. Sanderson, Tanya Gupta, Kimberly A. Penning

Iowa Science Teachers Journal

This article discusses and compares two approaches to teaching students about aerobic and anaerobic respiration. One approach was to have students take part in a common cookbook activity where a preset procedure is followed. In the second approach, students completed the same activity, th but in a more inquiry-oriented fashion. Each approach was implemented in two 10 grade classes. Students experiencing the inquiry approach were observed spending more time discussing the targeted concepts, and they performed better on the end-of-unit test. This article addresses National Science Education Standards A, C, and G and Iowa Teaching Standards 1, 2, 3, 4, …

Weapons Of Mass Instruction: The Teacher’S Crucial Role In Promoting A Deep Understanding Of Conservation Of Mass, Matthew Moffitt, Joseph Miller Jan 2008

Weapons Of Mass Instruction: The Teacher’S Crucial Role In Promoting A Deep Understanding Of Conservation Of Mass, Matthew Moffitt, Joseph Miller

Iowa Science Teachers Journal

Conservation of mass is a counter-intuitive idea that students struggle to fully comprehend (Stavy, 1990). This article presents a modified version of a conservation of mass demonstration. The original activity has much potential, but here we make clear the teacher's role that is necessary for promoting inquiry and deep mental engagement. We also discuss the use of several instructional “weapons” we have successfully used to enhance learning: questioning, wait time, listening, and nonverbal communication with students. We include numerous sample questions that we ask to encourage students to share their ideas, and help students come to the desired understanding. This …


Density With Intensity, Michelle State, Laurie Mcghee Jan 2008

Density With Intensity, Michelle State, Laurie Mcghee

Iowa Science Teachers Journal

This article presents a guided-inquiry activity where students apply their emerging understanding of density. Students are presented with the question of how different solids and liquids will arrange themselves when placed together. However students are not allowed to physically put them together. With teacher guidance and scaffolding, students determine that they can solve the problem by calculating and comparing the densities of the various substances. This activity would best be used in grades 8-12 in the application phase of the learning cycle, or modified to become a summative assessment for a density unit. This article also discusses the crucial role …

How "Bright" Is It To Use Cfls? A Look At The Controversy, Roxanne Greitz Miller Jan 2008

How "Bright" Is It To Use Cfls? A Look At The Controversy, Roxanne Greitz Miller

Education Faculty Articles and Research

Commonly referred to as CFLs, compact fluorescent light bulbs are rapidly replacing traditional incandescent light bulbs for residential use. However, controversy and even comic parody have arisen surrounding CFL use. CFLs contain small amounts of mercury, and several public forums and news agencies have been announcing that the breakage of a CFL in one's home may result in exposure to dangerously high mercury levels that can cause serious physical side effects. The purpose of this article is to introduce the basics of how incandescent and compact fluorescent light bulbs work, explain why the switch to CFLs is being promoted, and …

Mathematicians Playing A Role In Math Education: What We Learned At The Ime/Mime Workshop, Anna Bargagliotti, Rama Chidambaram, Gizem Karaali

Pomona Faculty Publications and Research

In Hollywood, some actors are regularly cast as mean, others as sweet and endearing, and some typically play innocent big-eyed youths who inevitably succeed after awakening to the particular facts of life that their producer wants them to awaken to. It is unusual and difficult for actors to cross the bridge between different types on a regular basis. However, there are always exceptions to the rule.

In the seemingly unrelated world of academics, mathematics faculty may find themselves playing different roles. People with different skills and interests strive to balance their careers in ways that will be uniquely fulfilling to …

Using Landscape History And Baseline Data In The Restoration Of A Midwestern Savanna, Andrew P. Rayburn, Annabel L. Major Jan 2008

Using Landscape History And Baseline Data In The Restoration Of A Midwestern Savanna, Andrew P. Rayburn, Annabel L. Major

Journal of the Iowa Academy of Science: JIAS

Over one hundred and fifty years of Euro-American settlement has dramatically altered Midwestern landscapes, resulting in the widespread conversion of native habitat. Numerous opportunities to conduct ecological restoration exist within the Midwest, with the potential to increase habitat and landscape heterogeneity, secure critical ecosystem services, and provide opportunities for research and education. Site history is an important consideration for most restoration projects, and multiple sources of historical data may be required to unravel the complicated history of intensively used Midwestern landscapes. The collection of baseline data is another significant component of most restoration projects, allowing for an evaluation of community …


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 Jan 2008

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 …

Obituary: Terry Lamon Yates, 1950-2007., Robert J. Baker, David J. Schmidly, Joseph A. Cook, Jorge Salazar-Bravo, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

On December 11, 2007, the science of mammalogy lost one of its most valued and influential leaders. Terry Lamon Yates succumbed to complications of treatments for an aggressive form of brain cancer after a brief but courageous fight. He was born on March 17, 1950, in Mayfield, Kentucky, the older son of Ellen Wanda Byrd and William Hanley Yates. Terry’s only sibling was a brother, Johnny. He is survived by his wife Nancy Fennell Yates, his two sons, Brian Christopher and Michael Ryan, and daughter-in-law Laura Manchéno Macia.

Teaching As A Sacred Activity, Michael P. Clough Jan 2008

Teaching As A Sacred Activity, Michael P. Clough

Iowa Science Teachers Journal

Many years ago I received an e-mail from one of my students that directed me to a writing of Louis Schmier titled “Holiness in Teaching.” Most of my former students have recognized my deep conviction that teaching is a very important undertaking. During the first fifteen or so years of my career they must have perceived this from the way I interacted with them and spoke about the responsibilities of teachers and schools, because I rarely stated explicitly that teaching is a sacred activity.


Tracking Mass: Putting The Thinking In Students’ Hands Leads To Deeper Conceptual Understanding Of Conservation Of Mass, Christopher J. Kurtt Jan 2008

Tracking Mass: Putting The Thinking In Students’ Hands Leads To Deeper Conceptual Understanding Of Conservation Of Mass, Christopher J. Kurtt

Iowa Science Teachers Journal

This article first presents a cookbook activity that leads students step-by-step through determining the density of a gas produced in a chemical reaction. This activity is problematic for two reasons. First, students may simply follow the provided directions without really understanding the investigative set-up and procedure. Second, the cookbook activity ignores the difficulties students have accepting that gases have mass and that mass is conserved in chemical reactions. I illustrate how the activity may be modified to address the common misconception that gases have no mass, and develop a deeper understanding of conservation of mass. This article promotes National Science …
