How Do You Mass What You Cannot See? Using Paper Clips To Help Students Learn How Electron Mass Was First Measured, Rob Hingstrum, Jacob Pleasants, Shannon Mclaughlin
Iowa Science Teachers Journal
Many students wrongly presume that scientific knowledge is mysteriously discovered and often believe the development of this knowledge is beyond their ability to comprehend. The activity presented here – appropriate for high-school chemistry and physics students – challenges these misconceptions. Students are engaged in thinking and creativity similar to how the first scientists accurately measured the mass and charge of an electron. Through this process, students develop a deep understanding of how the mass and charge of an individual electron was determined. This activity addresses National Science Education Standards A, B, E, and G and Iowa teaching Standards 1, 2, …

The Buds And The Bees: Inquiry Into The Sexual Reproduction Of Plants, Timothy D. Goodman, Laurence H. Woodruff
Iowa Science Teachers Journal
Many students have few significant experiences investigating flower structure and function, yet are expected to understand sexual reproduction in angiosperms. We present here an inquiry-based hands-on activity where middle school students compare plant reproduction to more commonly understood animal reproduction. This provides a foundation to more deeply understand topics related to plant reproduction. This activity also provides many opportunities to explicitly address the nature of science and how science works. This article addresses National Science Education Content Standards A, C, and G, and Iowa Teaching Standards 1, 2, 3, 4, and 5.

Parts Of The Whole : Cognition, Schemas, And Quantitative Reasoning, Dorothy Wallace
Numeracy
Based loosely on ideas of Jean Piaget and Richard Skemp, this Parts of the Whole column considers the construction of knowledge in mathematics and quantitative reasoning. Examples are chosen that illustrate an important cognitive difference between quantitative numeracy and classical mathematics, and which illuminate the particular choices instructors must make in order to teach either or both of these.

Flood Frequency Estimation By Neyman-Scott Rectangular Pulse Rainfall Model And Topmodel, Richard Bernatz
Journal of the Iowa Academy of Science: JIAS
A spatial-temporal Neyman-Scott Rectangular Pulse (NSRP) stochastic rainfall model is developed for seasonal-continuous simulation to project annual discharge probabilities from a relatively small watershed, the 1395 km2 Upper Iowa River watershed upstream from Decorah, Iowa. NSRP rainfall data is used as rainfall input to TOPMODEL, a conceptual, semidistributed rainfall runoff model, to calculate river discharge at a site common to the United States Geological Survey (USGS) gauging station in Decorah, Iowa. Annual peak flows based on simulated rainfall are used to fit a log-Pearson type III distribution to project 1 %-, 0.2%-, and 0.1 %-annual discharges. These results are compared …

University of Texas at El Paso
Computational Fluid Analysis Of G-12 Parachute, Jesus Lucio Valles
Open Access Theses & Dissertations
The main focus is on the Computational fluid interaction of the effect of parachutes in use on stresses and forces in the material. Constant research is being done to understand how air behaves when it interacts with parachutes. Due to the high turbulence and chaotic air behavioral, it is difficult to predict the behavior of the parachute. The stresses and pressure measurements are nearly impossible to take when in actual use. By simulating such problem in a computer software major advancement is made. The measurements are now taken and the behavior of the parachute is obtained. Rather than having to …

I Have A Solution To Share: Learning Through Equitable Participation In A Mathematics Classroom, Mary Q. Foote, Rachel Lambert
Education Faculty Articles and Research
Student participation is an issue of equity. Without participation there can be no learning. This study focuses on the participation (and therefore learning) of struggling students (those with individual education plans [IEPs]) during the implementation of a relational thinking routine in a third-grade inclusion classroom. Students with IEPs often initially used direct modeling with linking cubes as a resource for presenting their thinking. In this way, they were able to demonstrate their ability to think relationally. As the year progressed, these students, who had earlier been reluctant to share and had done so only by using several of the resources …

Teaching & Learning Faculty Publications
In today’s world of ubiquitous computing there are a number of technologies available to K-12 educators for teaching and learning mathematics. However, Koehler and Mishra (2008) have described how teaching and learning with such technologies presents a “wicked problem,” as it can involve a number of variables, independent of each other and contextually bound, that need to be brought together. This article highlights the advantages technology offers for mathematics education and looks at some of the reasons behind the poor uptake, such as teacher beliefs and lack of training. A number of solutions are offered to address these issues, including …
