Effects Of Nest Site Environment And Timing Of Breeding On Reproductive Success In Franklin's Gulls (Larus Pipixcan), Emily Anne Berg Jan 2009

Effects Of Nest Site Environment And Timing Of Breeding On Reproductive Success In Franklin's Gulls (Larus Pipixcan), Emily Anne Berg

Biological Sciences

Offspring performance and phenotype are affected by genotype and environment, which in birds includes yolk resources (part of the embryonic environment). Female colony nesting birds may influence offspring competitive ability in the post-hatching nest site environment by differentially allocating yolk resources to eggs based on nest site characteristics. Offspring performance may also be linked to prenatal allocation of resources, as well as post-natal parental care. Nest site characteristics, including nest size, density, and timing of breeding, influence the behavior (e.g., aggressive, social) and resource acquisition of the parents, as well as provide measureable variation in the postnatal environment. I used …

Faculty Publications

Background: Few teachers and special education specialists are aware of the materials and resources available to support science; technology; engineering; and mathematics instruction for the scattered and isolated 3000 students with sensory and motor disabilities in Iowa's K-12 schools. Additionally; faculty at many community colleges and regent institutions are not aware of possible accommodations for their students with disabilities who have interests in pursuing STEM careers. Unfortunately; this often leads to discouragement and lack of success for students with motor or sensory disabilities. This conference brings together experts and conference attendees involved in instruction; support; or transitions for these students …


Aryl Ethers From Arenediazonium Tetrafluoroborate Salts: From Neat Reactions To Solvent-Mediated Effects, James A. Shriver, Daniel P. Flaherty, Cameron C. Herr Jan 2009

Aryl Ethers From Arenediazonium Tetrafluoroborate Salts: From Neat Reactions To Solvent-Mediated Effects, James A. Shriver, Daniel P. Flaherty, Cameron C. Herr

Journal of the Iowa Academy of Science: JIAS

A general procedure for the synthesis of various aryl ethers via the thermal decomposition of benzenediazonium tetrafluoroborate salts is described. Studies performed in neat alcohol at 60°C gave aryl ethers in yields ranging from 0-73%. Upon completion of a series of reactions, the effect of solvent was explored to expand the scope and relevance of this procedure. It was found that even solvents that are traditionally non-nucleophilic gave rise to products including bi-aryls and N-aryl acetamides. The utilization of an ionic liquid, l-butyl-4-methylpyridinium tetrafluoroborate, resulted in yields comparable to reactions performed in neat alcoholic solvents.


The Freshwater Mussels (Mollusca: Bivalvia: Unionidae) Of The Channelized Missouri River, Ellet Hoke Jan 2009

The Freshwater Mussels (Mollusca: Bivalvia: Unionidae) Of The Channelized Missouri River, Ellet Hoke

Journal of the Iowa Academy of Science: JIAS

The lower Missouri River has historically been viewed as a fauna! barrier for unionids due to high sediment load. However this survey of the lower (channelized) Missouri River documented the presence of 14 unionid species and the exotic Corbicula fluminea (Muller, 1774). Unionids are present in stable substrates sheltered from the effects of the river's strong currents. Analysis of early literature on the Missouri River suggests reports of an absence of unionids were not based upon thorough fieldwork, and the most commonly cited rationale for their reported absence, the high sediment load in the river, is not convincing. Pre-1938 unionid …

Meaningful Distributed Instruction— Developing Number Sense, Edward C. Rathmell Jan 2009

Meaningful Distributed Instruction— Developing Number Sense, Edward C. Rathmell

Faculty Work

What Is Number Sense?

The primary goal for elementary and middle school mathematics is to help students learn to use numbers meaningfully, reasonably and flexibly in everyday life. This means that students must develop a deep understanding of

-- numbers and operations,
-- when operations can appropriately be used to solve problems, and
-- judging the reasonableness of their solutions to problems.

They also need to develop attitudes so they

-- believe they can make sense of mathematics, and
-- habitually try to make sense of mathematics.

In other words, students need to develop number sense.

Understandings Needed for Number …


Conceptual Previews In Preparation For The Next Unit Of Instruction, Michele Carnahan, Bridgette Stevens Jan 2009

Conceptual Previews In Preparation For The Next Unit Of Instruction, Michele Carnahan, Bridgette Stevens

Faculty Work

Understanding meanings of operations and how they relate to one another is an important mathematical goal for students in fourth grade (National Council of Teachers of Mathematics, 2000). Using pictures, diagrams, or concrete materials to model multiplication helps students learn about factors and how their products represent various contexts. The foundation of understanding how operations of multiplication and division relate to one another deepens the understanding of the composition of numbers. Discussing different types of problems that can be solved using multiplication and division is important, along with the ability to decompose numbers. When students can work among these relationships …


Personal Epistemologies And The Learning Paradox In Teacher Education: A Neglected Dilemma, Elana Joram, Carmen Montecinos Jan 2009

Personal Epistemologies And The Learning Paradox In Teacher Education: A Neglected Dilemma, Elana Joram, Carmen Montecinos

Faculty Publications

In this chapter, we discuss the role that personal epistemologies play in teacher education, particularly with respect to the potential problems and roadblocks they may present. We suggest that epistemological beliefs govern the kind of knowledge that preservice teachers consider to be legitimate and worthwhile learning in their programs, regulate the ways in which they make choices among competing knowledge claims and justify their own choices. A body of research has examined epistemic cognition as a dimension of the cognitive growth that occurs during the college years (e.g., Baxter- Magolda, 2002; King & Kitchener, 2002; Perry, 1970), and recently, the …

Cooking : Mixing And Measuring With Young Children, Aimee Marie Klostermann

Graduate Research Papers

Cooking with young children is a rewarding experience as an educator. Not only are the children enjoying themselves, but you are too. Cooking allows children to be in touch with their senses, and is a hands-on approach to learning. Of course cooking can be messy, which is what young children love most. Incorporating science, math, literacy, and social studies into one activity is easily done through cooking.

Whether you are a novice or a veteran when it comes to cooking, the skills children gain are immense when you incorporate cooking into the early childhood curriculum. I believe there are some …
