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

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 …

What I Believe About Leadership And Education : Reflective Research, Trent A. Jeffrey

Graduate Research Papers

In the field of education, having a great leader is very important. The principal is like a captain of a ship. He can lead that ship right down the middle so that his students and staff can see things from both sides or he can run aground and really cause some problems. Leadership is something that must come from within. You can definitely tell when you are around someone that is a natural leader and someone who is trying their hardest.

A leader is someone who is well read on the new and innovative changes in education. They are caring, …

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.

Mediators' Face Dimensions: A Factor Analysis, Sook-Young Lee

Iowa Journal of Communication

The purpose of this study is to explore dimensions of face-concerns of an informal mediator in the intercultural setting. Ting-Toomey and her colleagues' definition and dimensions of face-concerns are used as a framework to create a scale for face-concerns of a mediator who is to handle an intercultural conflict episode. Data were collected from 207 participants from the U.S., China, Taiwan, and South Korea. The Principle Component Analysis was conducted to discover the dimensions of face-concerns. The results both support and challenge current theoretical frameworks for face-concerns. Practical and methodological implications are discussed.

Developing Writers, Ann Craig

Graduate Research Papers

As our nation focuses on educational reforms in reading, math, and science, the place of expository writing within subject areas becomes evident. Students are required to write for different purposes within their classes, often expected to draft, explain, and interpret ideas offered by their educational experiences. Unfortunately, teachers find many of their students unable to understand their directions for writing. An approach that balances writing instruction with self-regulation as students write may help them internalize different aspects of writing expository papers as a means of communication in their classes. This paper, therefore, examines an instructional writing strategy, specifically self-regulated strategy …

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. …

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 …

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 …

A Preferred Vision For Leading Elementary Schools : A Reflective Essay, Melinda S. Dunlap

Graduate Research Papers

There are many qualities needed for a principal to be an exemplary educational leader. A leader needs to be strong in supporting parental involvement, providing meaningful staff development, attracting and retaining quality teachers, and being a leader in technology. By being strong in these four areas, a leader is off to a great start on the road to becoming "the main educational facilitator of the learning community" (Wilmore, 2002, p. 5).

The Unknown Factor: Helping Students Understand Mendelian Genetics And The Nature Of Science, Chris Robinson

Iowa Science Teachers Journal

Teaching science concepts in the same chronological order that the knowledge was developed by the scientific community is an effective way of promoting understanding of the concept as well as a greater appreciation for scientific inquiry. This activity mentally engages students and provides them a sense of discovery that Gregor Mendel must have felt over 150 years ago when he came to understand inheritance. Finally, by putting Mendelian genetics into a historical perspective, students will gain a greater understanding of scientific processes and the history and nature of science. This activity promotes National Science Education Content Standards A, C, E …

The Study Of Computational Fluency, Cassandra Hart

Graduate Research Papers

Teachers, educators and researchers are still attempting to reach consensus on the kinds and amounts of computational fluency that are relevant for today's classroom. But one thing is certain, computational fluency is one of the most vital components of developing mathematical understanding. It is absolutely necessary that students have knowledge of basic number relationships and the ability to choose from a number of appropriate strategies. The question to be answered in this study is how can Computational Fluency strategies enhance student achievement in math and improve the current climate for learning? This study evaluated the implementation of the Computational Fluency …

Components Of Inclusion, Jodi Janssen

Graduate Research Papers

As a special education teacher, I have always had a personal desire for inclusion to happen, and believed it could have benefits for all children of identified disabilities. After a recent transfer to a new school, the administration informed me I'd be teaching kindergarten with full inclusion for my special needs students. I was very excited about the prospect, but I was not armed with any solid information on how to approach a full inclusion model. As the school year progressed, my team and I forged ahead and I began researching what literature had to provide on the components needed …

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 …

Zoology Teams In Action: Using Animals To Initiate Scientific Inquiry, Kat Hudson

Iowa Science Teachers Journal

The benefits of using animals in the science classroom have been discussed, debated and written about for some time. Using animals as initiators of inquiry-based science and managing the welfare of the animals by creating student-run “Zoology Teams” is addressed in this article. This article promotes National Science Education Content Standards A, C, and F, and Iowa Teaching Standards 1, 2, 3, 4 and 8.

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

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, …

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

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

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.

Use Of Artificial Enclosures To Determine The Survival Of Rana Pipiens Larvae In Upper Midwestern Agricultural Ponds, Joshua M. Kapfer, Mark B. Sandheinrich, Melinda G. Knutson

Journal of the Iowa Academy of Science: JIAS

Amphibians in the upper Midwest use agricultural ponds for breeding. Unfortunately, the risks (both direct and indirect) associated with using these ponds are poorly understood in both amphibian adults and larvae. In order to quantify these risks, we performed a comparison of larval survival rates between agricultural and natural ponds in southeastern Minnesota during the spring and summer of 2001. During this time, larval survival was observed in Rana pipiens tadpoles raised through metamorphosis in enclosures placed in agricultural and natural ponds. In addition, we measured the levels of nutrients commonly linked with agricultural ponds (i.e., ammonia, total phosphorous, and …
