Health Literacy In The Mathematics Classroom: The Iowa Core Curriculum As An Opportunity To Deepen Students’ Understanding Of Mathematics, Elana Joram, Susan Dobie-Roberts, Nadene Davidson

Faculty Publications

By 2012, all high schools in Iowa will be required to incorporate the new Iowa Core Curriculum, followed by elementary and middle schools in 2014 (Iowa Department of Education, 2009). The Iowa Core Curriculum addresses the question: "How is Iowa's educational system preparing our youth for successful lives in the 21st-century global environment?" (Davidson, 2009). It consists of core content standards, and identifies essential concepts and skills for content areas. The Iowa Core Curriculum also includes the ―21st Century Skills‖ of ―health, financial, technology, and civic literacy, and employability skills. These skills are to be infused into existing subject matter …

Enhancing Iowa High School Students' Transition To College, K. E. Lassila, L. C. Rule, C. Lee, R. J. Driggs, G. Fulton, M. Skarda, J. Torres Y Torres

Journal of the Iowa Academy of Science: JIAS

We present our studies of the transitions of Iowa science students from high school to post-secondary colleges. Our report summarizes information and impressions from dealing with thousands of new students arriving at our six colleges, along with meetings and discussions with high school science teachers to add their viewpoints into our considerations. Feedback from community college, four year college, and high school science teachers highlighted the following five study issues and needs for improving student transitions from high school to college science: 1) Better math preparation is needed; 2) More work with inquiry-based learning rather than with facts and memorization …

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

Faculty Publications

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 …

Gully And Stream Bank Erosion In Three Pastures With Different Management In Southeast Iowa, George N. Zaimes, Richard C. Schultz, Mustafa Tufekcioglu

Journal of the Iowa Academy of Science: JIAS

Gully and stream banks can be major sources of sediment and nutrients to surface waters, both major water quality problems in the United States. Sediment may also carry phosphorus to surface waters, the primary limiting nutrient causing eutrophication. Overgrazing can induce gully and stream bank erosion by reducing vegetation cover that weakens bank soil resistance to stream water flow. This study examines stream and gully bank erosion adjacent to continuous (CP), rotational (RP) and intensive rotational (IP) pastures, grazed by beef cattle in southeast Iowa. Stream and gully bank erosion were measured by: a) surveying the extent of the severely …

Dr. Lois Hattery Tiffany (1924-2009): In Memoriam, Deborah Q. Lewis

Journal of the Iowa Academy of Science: JIAS

Dr. Lois Hartery Tiffany, Distinguished Professor Emerita, Department of Ecology, Evolution and Organismal Biology, Iowa State University, Ames, Iowa, died on 6 September 2009. Dr. Tiffany was an outstanding mycologist and teacher. Held in high regard by the public as "Iowa's Mushroom Lady" and known by many students, colleagues and friends as "Dr. T.," she was the matriarch of the Botany Department (now the Department of Ecology, Evolution and Organismal Biology) at Iowa State.

Som Loss And Soil Quality In The Clear Creek, Ia, A. N. Thanos Papanicolaou, Christopher G. Wilson, Ozan Abaci, Mohamed Elhakeem, Mary Skopec

Journal of the Iowa Academy of Science: JIAS

The Clear Creek, IA Experimental Watershed (CCEW), which drains to the Iowa River, experiences severe surface erosion due to a combination of high slopes, erodible soils, and extensive agriculture. Concurrent with soil loss is the removal of Soil Organic Matter (SOM). High values of SOM have been related to soil quality; therefore, excessive SOM loss corresponds to degrading soil health. Soil quality assessments are important tools for evaluating management practices in agricultural systems; however, it is difficult to measure soil quality directly at the watershed scale because it varies with a number of site-specific soil characteristics. The coupling of soil …

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 Iowa Core Curriculum And Me: How My Teaching Of Mathematics Methods Will Change, Catherine M. Miller

Faculty Publications

It is an exciting time to be a mathematics educator in Iowa! We are joining the other 49 states by having a set of state standards. In fact, Iowa is exceeding federal expectations by having a curriculum to inform the work of teachers and school administrators. Because of this, we enter an era of change in Iowa and, as we know, change is never easy. To succeed in implementing the Iowa Core Curriculum (ICC) in mathematics all teachers need to learn about it and have help in implementing its core ideas and content. This includes teachers who will begin their …

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

Faculty Publications

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 …

Skittles Chocolate Mix Color Distribution: A Chi-Square Experience, David R. Duncan, Bonnie H. Litwiller

Faculty Publications

In teaching statistical processes, it is important that there be application to realworld settings and activities. When this is done, students are more likely to see the meaning of the steps being developed.

One such activity involves using the Chi-Square statistical test and its applications to counting Skittles Chocolate Mix candies. Many students are aware that these candies come in five different flavors: Brownie Batter (BB), Vanilla (V), Chocolate Caramel (CC), S’mores (S), and Chocolate Pudding (CP).
