The Teacher's Crucial Role In Helping Students Learn Through Inquiry, Michael P. Clough
The Teacher's Crucial Role In Helping Students Learn Through Inquiry, Michael P. Clough
Iowa Science Teachers Journal
Learning and effective teaching are both highly complex acts. Leinhardt and Greeno (1986, p. 75) write that "teaching occurs in a relatively ill-structured, dynamic environment". Classroom conditions change in unpredictable ways, and information arises during the act of teaching that by necessity must inform practice as it occurs. While this is true of all teaching, it is all the more so when effectively teaching science through inquiry. This, in part, may explain the all too common practices of lecturing, textbook assignments, worksheets, and cookbook activities in science teaching. Each of these approaches severely constrains students' input into a lesson and …
Winging It: Exploring Form And Function Using Chicken Wings, Kyle Girup, Mike Klein
Winging It: Exploring Form And Function Using Chicken Wings, Kyle Girup, Mike Klein
Iowa Science Teachers Journal
This article presents a modification of a “cookbook” laboratory activity addressing the structure and function of a chicken wing. While the original activity was interesting, it did most all the thinking for students. The problem solving, creativity, and cooperative learning demanded in the modified activity requires students to think deeply about what they are doing and the relationship between structure and function. In doing so, students develop a better understanding of this important concept and the nature of scientific work. This activity promotes National Science Education Content Standards A and C and Iowa Teaching Standards 1, 2, 3, 5, 6, …
Rounding Up Students' Conceptions On Circular Motion, Shannon Mclaughlin
Rounding Up Students' Conceptions On Circular Motion, Shannon Mclaughlin
Iowa Science Teachers Journal
The purpose of this paper is to provide insight on how introducing circular motion with a carefully designed sequence of demonstrations and activities consistent with the national standards, pedagogical knowledge, and research-based instructional practices can flush out students' conceptions of forces and motion, and set a conceptual foundation for understanding uniform circular motion. This article promotes National Science Education Content Standards A, B, and E, and Iowa Teaching Standards 1, 2, 3, and 4.
Circuits Without Wires?: Helping Students Understand The Power Of Ions, Elizabeth Potter, Caroline Kelly
Circuits Without Wires?: Helping Students Understand The Power Of Ions, Elizabeth Potter, Caroline Kelly
Iowa Science Teachers Journal
The activity described here provides an inquiry experience using familiar materials to promote student exploration and understanding of ions and ionic compounds. Familiar materials throughout the laboratory help students relate science to the real world and students are able to use their understanding of those materials. This activity uses an inquiry approach that requires students to make more decisions about their experiment, but does not expect students to discover scientific ideas. This article identifies many ways that the nature of science should be incorporated into the learning experience so that students improve their understanding of what science is and how …
Making A Splash: A Population Study Of Orcas And Its Application For Student Inquiry In Iowa, Laura Howell
Making A Splash: A Population Study Of Orcas And Its Application For Student Inquiry In Iowa, Laura Howell
Iowa Science Teachers Journal
The author participated in an Earthwatch Institute sponsored population survey of the Southern Resident Orca (killer whales). The two main aspects of this survey were to study the Orca population and to monitor the effects of humans on them. Orcas are listed as a "threatened" species and their population is currently declining. Results of the study linked the presence of the pollutant Polychlorinated-biphenyls (PCBs) in the ocean to this decline. Students will use the procedures outlined by this research to conduct their own population study on their local community. They will go to the cemetery to collect the mortality (death …
Knowing Versus Understanding: Teaching That Goes Beyond Trivialities, John Stiles
Knowing Versus Understanding: Teaching That Goes Beyond Trivialities, John Stiles
Iowa Science Teachers Journal
In this century of science and technology, it is essential that students learn to critically assess science issues in historical perspectives. The traditional method of teaching students to memorize information bits cannot accomplish the goal of creating a science- and technology-literate public. However, if teachers transform their learning environment into one that encourages and supports student conceptual understanding, not only will graduates be able to make informed decisions regarding science, but numerous studies show that student achievement also increases, often dramatically. This article promotes National Science Education Content Standard A and Iowa Teaching Standards 1, 3, 4, 5, and 8.

Learning Science As And Through Inquiry, Michael P. Clough
Learning Science As And Through Inquiry, Michael P. Clough
Iowa Science Teachers Journal
Inquiry science teaching has been at the heart of science education reform efforts for as long as most of us can remember. Clearly, the longstanding efforts to move science education in this direction are not a passing education fad. However, confusion often exists regarding what inquiry science teaching means and what it looks like in the complex world of classroom teaching. Inquiry science teaching may refer to teaching science as inquiry (helping students understand how scientific knowledge is developed) or teaching science through inquiry (having students take part in inquiry activities to help them come to more deeply understand science …
Every Learner Inquires: A State Science Education Initiative, W. Tony Heiting
Every Learner Inquires: A State Science Education Initiative, W. Tony Heiting
Iowa Science Teachers Journal
Learning, by its very nature, is an active mental process whereby learners work to make sense of experience in light of what they already know. Learning through inquiry encourages extensive mental engagement and, when implemented well, promotes a deep understanding of science concepts and the nature of science. For these reasons, having students learn science through inquiry has been at the heart of science education reform documents. However, teaching science through inquiry requires particular teaching skills that depart from time-honored practices. This article describes a new state science education initiative in Iowa titled “Every Learner Inquires” (ELI) that will begin …
Rethinking The Rollercoaster: A Multi-Disciplinary Approach To Promoting Science Inquiry, Timothy Nordin
Rethinking The Rollercoaster: A Multi-Disciplinary Approach To Promoting Science Inquiry, Timothy Nordin
Iowa Science Teachers Journal
References to amusement park rides are often made when teaching students about motion and other physics concepts. The activity presented here goes further and engages students in using physics concepts, and extending this understanding to new concepts, including building roller coaster models that actually work. The value of the activity presented is its ability to promote several important goals for science learning, as well as describing the teachers' crucial role. This article promotes National Science Education Content Standards A, E, F, and G and Iowa Teaching Standards 2, 3, 5, and 6.
The Helping Hand: An Administrator's Role In Encouraging And Supporting Effective Science Teaching, Robert L. Clark
The Helping Hand: An Administrator's Role In Encouraging And Supporting Effective Science Teaching, Robert L. Clark
Iowa Science Teachers Journal
Science teaching that mentally engages students and promotes all the goals we have for students, including a deep understanding of science content and the nature of science, is extremely difficult. That sort of teaching deviates significantly from the time-honored approaches that have permeated our schools for as long as any of us can remember. Because of that, many institutional constraints exist that make implementing effective science teaching even more difficult. This article addresses the principal's crucial role as an educational leader, the principal's responsibility to encourage and support effective science teaching practices, and efforts made in one building toward these …
Colorblindness: Invisible Disability, John Stiles
Colorblindness: Invisible Disability, John Stiles
Iowa Science Teachers Journal
In nearly every classroom sits at least one student who is unable to distinguish between certain colors. This incurable, genetic, and sex-linked condition is particularly frustrating in science class, a subject in which color discrimination is frequently required. Teachers are often unaware of this invisible disability, which many "colorblind" students try to keep secret in order to avoid embarrassment. There are a number of modifications a science teacher can make to reduce, or in some instances remove, barriers to learning for colorblind students. In addition, a simple, free test may help identify young children who have color difficulties, so they …

The Phenomenon Of Math Anxiety, Mary S. Fliehler
The Phenomenon Of Math Anxiety, Mary S. Fliehler
Graduate Research Papers
Math anxiety has cognitive, physical, and affective components. The physical component is recognizable by sweaty palms, nausea, rapid heart rhythm, and shortness of breath – all of which are the body's response to anxious feelings. The affective component is displayed through lack of confidence in one's ability to accomplish the required mathematics computations, avoidance of studying mathematics, limitations of career choices, and an over-all sense of helplessness when confronted with mathematical situations. The cognitive component occurs when the anxiety reaches a level that reduces the efficiency of the working memory in the brain while learning new mathematical concepts. Tobias, a …

Changes In Land Cover And Breeding Bird Populations With Restoration Of Riparian Habitats In East-Central Iowa, Thomas J. Benson, James J. Dinsmore, William L. Hohman
Changes In Land Cover And Breeding Bird Populations With Restoration Of Riparian Habitats In East-Central Iowa, Thomas J. Benson, James J. Dinsmore, William L. Hohman
Journal of the Iowa Academy of Science: JIAS
Conversion of Midwestern riparian areas for agricultural production has greatly altered their function and suitability for birds and other wildlife. Recently, however, restoration of riparian functions has been a major focus of land management agencies in the Midwest. We used historic land-use data to describe land-cover changes since European settlement and the subsequent effects of habitat restoration efforts on the landscape along a section of the Iowa River in east-central Iowa. We then used bird-density data collected in a subset of the study area in 2001 and 2002 to estimate changes in breeding bird populations of the entire study area …
Winter Bird Use Of Conservation Reserve Program Fields Harvested For Biomass, Les D. Murray, Louis B. Best
Winter Bird Use Of Conservation Reserve Program Fields Harvested For Biomass, Les D. Murray, Louis B. Best
Journal of the Iowa Academy of Science: JIAS
As Conservation Reserve Program (CRP) contracts expire, many fields may be returned to agricultural production. Growing switchgrass (Panicum virgatum) as a biomass fuel is an alternative to returning fields to rowcrops. CRP fields provide winter cover for birds, but the harvest of biomass would remove most of the cover and affect bird use of the fields. We estimated winter bird abundances in nonharvested, total-harvested, and partially (strip) harvested switchgrass fields in southern Iowa. Song sparrows (Melospiza melodia) were observed only in strip-harvested fields and ring-necked pheasants (Phasianus colchicus) were observed only in nonharvested fields and uncut areas of strip-harvested fields. …
Artists' Depictions Of Catsteps In The Loess Hills Of Iowa: Evidence For Mid-Nineteenth Century Climate Change, Kimberly R. Dillon, Steven H. Emerman, Pamela K. Wilcox
Artists' Depictions Of Catsteps In The Loess Hills Of Iowa: Evidence For Mid-Nineteenth Century Climate Change, Kimberly R. Dillon, Steven H. Emerman, Pamela K. Wilcox
Journal of the Iowa Academy of Science: JIAS
Catsteps are the staircase-like features common on hillslopes of the Loess Hills of western Iowa. The record of artistic depictions of the Loess Hills was examined to determine when catsteps appeared. George Catlin, Karl Bodmer, and John James Audubon traveled up the Missouri River m 1832, 1833 and 1843, respectively, and between them, produced 31 works of art depicting either the Loess Hills or the loess bluffs on the Nebraska side of the river. Only three works by Bodmer of Blackbird Hill on the Nebraska side possibly show catsteps. The Assistant State Geologist, Orestes St. John, produced six sketches of …
Silicification Of Corals, Stromatoporids, And Brachiopods At The Weathered Surface Within The Devonian-Age Little Cedar Formation (Solon And Rapid Members) In Eastern Iowa, Adam L. Majeski, Paul L. Garvin
Silicification Of Corals, Stromatoporids, And Brachiopods At The Weathered Surface Within The Devonian-Age Little Cedar Formation (Solon And Rapid Members) In Eastern Iowa, Adam L. Majeski, Paul L. Garvin
Journal of the Iowa Academy of Science: JIAS
Diagenesis of fossils contained in middle-Devonian limestones was studied at the Troy Mills and Robins quarries in Linn County, Iowa and at the Four County and Ernst quarries in Johnson County, Iowa. Fossils located at weathered bedrock surfaces were preferentially silicified, and the silicification affected corals, stromatoporids and, to a limited extent, brachiopods, but not other fossils or the host rock. The siliceous horizon extends no more than a few centimeters below the weathered surfaces, suggesting that silicification was constrained by them. Silica for silicification might have come from a variety of sources, including sponge spicules or radiolarian tests, insoluble …
