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 …

Richard Wallaschek's Nineteenth-Century Contributions To The Psychology Of Music, Amy B. Graziano, Julene K. Johnson

Music Faculty Articles and Research

RICHARD WALLASCHEK (1860-1917) is most widely known for his contributions to comparative musicology; however, he also made significant contributions to the field of music psychology. From 1890 to 1895, Wallaschek pursued interdisciplinary studies at the British Museum in London. During this time Wallaschek proposed theories about the perception and production of music. According to Wallaschek, the perception of music occurs through two types of mental representation: Tonvorstellung (tone representation), which referred to the perception of individual musical elements, and Musikvorstellung (music representation), which referred to the perception of the higher-order structure of music. Wallaschek emphasized Gestalt-like concepts in his discussion …

Historical Glacier And Climate Fluctuations At Mount Hood, Oregon, Karl Lillquist, Karen Walker

Geography Faculty Scholarship

Terminus fluctuations of five glaciers and the correspondence of these fluctuations to temperature and precipitation patterns were assessed at Oregon's Mount Hood over the period 1901–2001. Historical photographs, descriptions, and climate data, combined with contemporary GPS measurements and GIS analysis, revealed that each glacier experienced overall retreat, ranging from −62 m at the Newton Clark Glacier to −1102 m at the Ladd Glacier. Within this overall trend, Mount Hood's glaciers experienced two periods each of retreat and advance. Glaciers retreated between 1901 and 1946 in response to rising temperatures and declining precipitation. A mid-century cool, wet period led to glacier …

Projects That Assist With Content In A Traditional Organic Chemistry Course, John J. Esteb, John R. Magers, Luanne Mcnulty, Anne M. Wilson

Scholarship and Professional Work - LAS

Projects that engage undergraduate students in content-based courses, such as organic chemistry, must relate to the material and provide useful tools for the divergent needs of the students. There are few examples of these types of projects in the literature. Herein, we describe two projects, the reaction notebook and the end-of-semester synthesis activity. Each project is designed to stimulate student ownership of the material and leads to engagement with the content of the course.

Investigation Of Copper(Ii) Complexes: I Copper(Ii) Complexes Of Tryptophan And Its Analogues As Postcolumn Interaction Components For Indirect Fluorescence Detection Of Amino-Containing Analytes Ii High-Performance Liquid Chromatographic Separation Of Copper(Ii) Azamacrocyclic Complexes, Xiaoxuan Shen

Doctoral Dissertations

The initial phase of this project investigates the use of copper(II) complexes of tryptophan and its analogues for indirect fluorescence detection in high-performance liquid chromatography. First, indirect photometric and fluorometric detection in high performance liquid chromatography (HPLC) is reviewed, giving the functional definition of indirect detection employed for this project, distinguishing different approaches to indirect photometric and fluorometric detection in HPLC, and explaining the basis of indirect fluorescence detection using copper(II) complexes of tryptophan and its analogues as postcolumn interaction components. Subsequent studies were conducted to develop and apply indirect HPLC detection for detecting specific mono-amino sugars, glucosamine, galactosamine, and …

Structural Analysis Of Cytokine Signaling Modulators, Cristina Ileana Silvescu

Doctoral Dissertations

The N-linked glycans attached to cytokine receptors modulate signal transduction by interacting with galectin-3 and generating a cell surface lattice. This opposes constitutive endocytosis and reduces the thresholds for cytokine signaling. The preferred ligands for galectin-3 are the poly-N-acetyl lactosaminylated tetra-antennary glycans which are synthesized by Mgat 5 and are present at high levels in tumor cells. A null mutation in Mgat 5 inhibits lattice formation and cancer progression in cells with an oncogenic background. GlcNAc feeding reestablishes lattice formation, cytokine signaling and tumorigenesis.

A MALDI-TOF analysis was employed to identify the N-glycans involved in modulating signal transduction in wild …

Improving Estimation Of Gross Primary Productivity Of Terrestrial Ecosystems, Qingyuan Zhang

Doctoral Dissertations

The MOderate Resolution Imaging Spectroradiometer (MODIS) provides an unprecedented opportunity to monitor and quantify seasonal changes of vegetation and phenology. MODIS has the potential to improve the estimation, which is based on the algorithms for the NOAA Advanced Very High Resolution Radiometer (AVHRR), of biophysical/biochemical variables of vegetation. My doctoral study improves estimation of gross primary productivity (GPP) through two aspects: first, my study improved the detection of vegetation phenology by distinguishing MODIS contaminated observations and contamination-free observations, and secondly, I inverted the fraction of absorbed photosynthetically active radiation (PAR) by chlorophyll using radiative transfer models and daily MODIS data. …

Soil Moisture Dynamics From Satellite Observations, Land Surface Modeling, And Field Data, Minha Choi

Doctoral Dissertations

Knowledge of soil moisture variability is essential to understand hydrologic processes at a range of scales. In this study, spatio-temporal variability of soil moisture and inter-comparison among different soil moisture products were analyzed. The variability patterns were well characterized by negative exponential fitting as function of observed sampling extent scale. The simple physical soil moisture dynamics model was identified as an alternative approach to characterize statistical soil moisture variability. The soil moisture variability was strongly related to physical properties including rainfall and topography.

Normal and log-normal distributions were recognized as the most efficient probability density functions to capture soil moisture …

Modeling Of Diffusional Creep And Stress Relaxation In Copper Grains During Manufacturing Of Microelectronic Integrated Circuits, Vasyl M. Grychanyuk

Doctoral Dissertations

The finite element technique was developed to study diffusional creep and stress relaxation in Cu grains with several atomic monolayers thick grain boundary region of enhanced diffusivity. The model was motivated by the need to study nanoscale back-end interconnect structures of microelectronic circuits. These structures have the length scale that does not conform to the assumptions of classical dimensional theories of diffusional creep.

Both diffusion and elasticity governing equations are considered in the coupled formulation of mass flow and stress analysis. Vacancy concentration field in the grains subjected to external load is coupled to stress field through diffusional creep strains. …

An Investigation Of Pre-Service Teachers' And Professional Mathematicians' Perceptions Of Mathematical Proof At The Secondary School Level, David M. Gray

Doctoral Dissertations

The National Council of Teachers of Mathematics [NCTM] states that by the time students graduate high school, they should learn to present "arguments consisting of logically rigorous deductions of conclusions from hypotheses" (NCTM, 2000, p. 56) in "written forms that would be acceptable to professional mathematicians" (NCTM, 2000, p. 58). Research studies indicate, however, that students and teachers have difficulty with many aspects of mathematical proof, including its nature and meaning. In addition, there appears to be a disconnect between school teachers' and university mathematicians' expectations for their respective students regarding mathematical proof. This study examined the perceptions of thirteen …

Characterization Of The Spatial And Temporal Variability In Pan-Arctic, Terrestrial Hydrology, Michael A. Rawlins

Doctoral Dissertations

Arctic hydrology represents an important component of the larger global climate system, and there are signs that significant water-cycle changes, involving complex feedbacks, have occurred. This dissertation explores the methods to estimate components of the arctic hydrological cycle, the numerous biases and uncertainties associated with the techniques, and suggestions for future research needs. The studies described here focus on quantitative models and methods for predicting the spatial and temporal variability in pan-Arctic hydrology.

This dissertation discusses pan-Arctic water budgets drawn from a hydrological model which is appropriate for applications across the terrestrial Arctic. Including effects from soil-water phase changes results …

Planar Algebras: A Category Theoretic Point Of View, Shamindra Kumar Ghosh

Doctoral Dissertations

We define Jones's planar algebra as a map of multicategories and construct a planar algebra starting from a 1-cell in a pivotal strict 2-category. We introduce the concept of affine representations of a planar algebra and prove some finiteness results for the affine representations of finite depth planar algebras. We also show that the radius of convergence of the dimension of an affine representation of the planar algebra associated to a finite depth subfactor is at least as big as the inverse-square of the modulus.

Exploring Lesson Study As A Form Of Professional Development For Enriching Teacher Knowledge And Classroom Practices, Melissa K. Mitcheltree

Doctoral Dissertations

This study tracked the development of teacher knowledge through a professional development experience called lesson study. Lesson study is a Japanese professional development process in which a group of teachers develop a series of lessons using the following stages: planning lessons, teaching/observing the lessons, reflecting on lessons taught as well as sharing and discussing the lessons with their colleagues (Lewis, 2002). The aim of this study was to explore how the lesson study process influenced teacher knowledge of mathematics content and pedagogical content.

Study participants were four secondary mathematics teachers from a rural high school in the Northeast. All participants …

Genetic Diversity And Gene Flow In Fragmented Populations Of The Rare Shrub, Calothamnus Sp. Whicher, Sean Stankowski

Theses : Honours

Ca/othamnus sp. Whicher (Myrtaceae) is a narrow range endemic shrub restricted to ironstone soils near the town of Busselton in south-western Australia. Due to extensive land clearing for agriculture and mineral exploration, the species is fragmented over the majority of its range. In the present study, microsatellite markers were used to characterise levels of genetic diversity and describe levels of differentiation and gene flow among seven small, isolated road verge populations. Allelic diversity within the taxon over the six microsatellites was high (A = 17.6 ± 1.6). Diversity within populations was considerably lower (A = 5.19 ± 1.27), …

Great Questions That Have Changed The World* (Hon 183), Dave Pruett

Honors in Practice Online Archive

“Which [do we] love more, the small island of [our] so-called knowledge or the sea of infinite mystery?” (Karl Rahner). “Great Questions” are those that radically alter our perceptions of physical reality, of self, and/or of our place in the universe. For example, Jacob Bronowski observed of Einstein that he was “a man who could ask immensely simple questions” from whose answers he could “hear God thinking.” Einstein’s theories of special and general relativity each originated from simple questions and Gedanken (thought) experiments that can be readily grasped by ordinary persons. It is the answers that are extraordinary. The course …
