Iowa Statewide Stream Nitrate Loading: 2017-2018 Update, Christopher S. Jones, Keith E. Schilling
Journal of the Iowa Academy of Science: JIAS
In response to ongoing hypoxia in the Gulf of Mexico, several states in the Mississippi River basin have adopted nutrient reduction plans in recent years designed to arrest the flow of nitrogen (N) and phosphorus (P) from both point and non-point sources to the stream network. Iowa’s Nutrient Reduction Strategy, implemented in 2012, aims to reduce stream loading of these nutrients by 45% within a yet-to-be-defined time frame. Because the state has chosen to integrate accountability into the strategy through the numerical objective, ongoing water monitoring is necessary to credibly measure progress. The primary objective of this research was to …

Application And Comparison Of Active Learning Implementation Methods In Biochemistry Education, Dylan Thibaut
Honors Undergraduate Theses
Biochemistry has continued to be one of the most complex and important subjects in science education. The purpose of this research is to investigate active learning implementation methods in a Biochemistry I context to determine the most effective means of preparing current science undergraduates. Two Biochemistry I classes over two semesters were analyzed in this study, with class A using a variable active learning schedule and class B using a consistent active learning schedule. Four aspects were analyzed to determine active learning validity: perception of different active learning properties, standardized final exam grades, class grade, and teaching implementation. The consistent …

Board 57: Identifying And Disseminating Transformative Professional Development Of Stem Undergraduates Who Perform Outreach: Progress In Year 1, Michael Alley, Joanna K. Garner
Division of Research and Economic Development Faculty & Staff Publications
To teach STEM content to K-12 students and to recruit talented and diverse K-12 students into STEM, many outreach programs at universities in the United States rely on STEM undergraduates. While the design of such outreach typically focuses on the K-12 students who are taught or recruited, an important but often overlooked consideration is the effect of the outreach on the professional development of the STEM undergraduates themselves. This proposed EAGER project seeks to determine which outreach programs in the United States provided the most transformative professional development of the participating STEM undergraduates. This project then seeks to capture the …

In recent decades, computational tools and methods have become pervasive in mathematical and scientific fields (National Research Council, 2010a). Tools such as mathematical and statistical models have expanded the range of phenomena that are explored and have become necessary for analyzing increasingly large data sets across disciplines (National Academy of Sciences, National Academy of Engineering, & Institute of Medicine, 2007). With these advances, entirely new fields such as computational statistics, neuroinformatics, and chemometrics have emerged. The varied applied uses of computational tools across these fields have shown that future scientists will not only need to know how to program, but …

Where would today’s world be without the number system? Indeed, civilization would not have come to as far as in modern times. In fact, the software this paper is being written on is run by a computer that is embedded in numerical codes and commands– something that would not be possible if it were not for the advancement of technology using the modern number system. In this paper, we study the historical development of the modern-day number system. We investigate the classification of numbers and number properties for mathematical use; including standard functions, rules, and examples. As a culmination of …

Today, humans as a species face significant global challenges: meeting the needs of an ever expanding human population for food and energy from limited land, water and other resources; finding ways to counter rapidly changing pathogens that become resistant to current treatments; adapting to climate change that is linked to more frequent flooding, drought, wildfires and temperature extremes; and reversing the deterioration of ecosystems associated with human induced alterations of the environment. Owing to its resilience and robustness, life in one form or another will likely persist, but it is unknown by what mechanisms or in what forms. Much is …

While institutions of higher education work to engage PK-12 youth in STEM (science, technology, engineering, and mathematics) concepts and careers via in-person programming, PK-12 teachers and students face many logistical and access constraints for physically traveling to sites off of school grounds during the school day. Throughout the years, electronic field trips (EFTs) have offered a digital way for schools to engage in meaningful ways with museums, parks, laboratories, and field research sites. In order for EFTs to be effective, they should be cost effective and created collaboratively with teachers, students, subject matter experts, and instructional design and communication professionals. …

A gathering of science, technology, engineering, and math (STEM) higher education stakeholders met in November 2018 to consider the relationship between innovation in education and assessment. When we talk about assessment in higher education, it is inextricably linked to both evaluation and accreditation, so all three were considered. The first question we asked was can we build a nation of learners? This starts with considering the student, first and foremost. As educators, this is a foundation of our exploration and makes our values transparent. As educators, how do we know we are having an impact? As members and implementers of …

This paper details the journey of a first-year teacher. It is a highly reflective exploration of their inner landscape – one that documents the development of the teaching self in relation to students and society at large. Separated into four distinct sections, this work serves as an account of personal motivation to teach, getting to know students beyond the classroom walls, immersion in the community to situate educational work, and a comprehensive reflection upon teaching effectiveness and the evolution of the educating self. Development as a professional educator as stated in Teacher Performance Expectation (TPE) 6 demands continual introspection and …

The purpose of this study is to examine the ways in which preservice secondary mathematics teachers (PSMT) professionally notice middle school students’ mathematical thinking on a technology enhanced mathematical task. The middle school students’ work was captured as a videocase for PSMTs to examine. Findings show that every PSMT included a discussion of the middle school students’ interaction with the technology in their noticing prompts, demonstrating that PSMTs recognized that the middle school students’ mathematical understanding was tied to their interactions with the technology. Additionally, results from PSMTs’ justifications for their predictions of middle school students’ responses to the task, …

Findings from physics education research strongly point to the critical need for teachers’ use of multiple representations in their instructional practices such as pictures, diagrams, written explanations, and mathematical expressions to enhance students' problem‐solving ability. In this study, we explored use of problem‐solving tasks for generating multiple representations as a scaffolding strategy in a high school modeling physics class. Through problem‐solving cognitive interviews with students, we investigated how a group of students responded to the tasks and how their use of such strategies affected their problem‐solving performance and use of representations as compared to students who did not receive explicit, …

The new approach to teaching science presented by the Next Generation Science Standards (NGSS) warrants training high-quality science, technology, engineering, and mathematics (STEM) teachers to prepare the future STEM workforce. We share the implementation of an energy lesson using a nanoscience approach, well-aligned with the NGSS vision, in a secondary- STEM-education course for preservice science teachers. First, we engaged preservice teachers in discussions related to alternate sources of energy; this was followed by a case-study approach to illustrate a real-world problem of energy deficiency and solar energy (solar cells using nanoparticles) as one potential solution because it is cost-efficient, clean, …
