Phone And Web Based Clicker Project, Nick Renford, Jeremy Straub, Scott Kerlin
Jeremy Straub
The goal of this project is to create an interface for Android,
iOS, and Windows Phone smartphones, as well as a web
interface that will act as a “clicker”. The
instructors will be able to send out questions, and the
students will be able to answer the questions, and get
feedback if the instructor wants them to have it. The teacher
can decide whether the feedback is instant or manually
initiated, and what format the response will be, whether it
includes the correct answer, and what type of chart, if any,
indicating the most commonly selected answer(s). There
will be …

The Use Of The Roofsat For Computer Science And Engineering Education, Jeremy Straub, Ronald Marsh
Jeremy Straub
This poster presents an overview of a tool that has been created to provide students with real-world experience in the design, development and operation of control and scientific mission software for a cyber-physical system. The ROOFSAT, developed at UND, is a low-cost analog for a small spacecraft (though in many ways these capabilities also enable similar UAV work). The ROOFSAT was constructed with approximately $1,500 generously provided by the John D. Odegard School of Aerospace Sciences out of commercially-available parts. It includes multiple cameras, a pan-tilt mount and the same space-qualified computer hardware which has been used on both spacecraft …

The aim of Delving Deeper is for teachers to pose and solve novel math problems, expand on mathematical connections, or offer new insights into familiar math concepts. Delving Deeper focuses on mathematics content appealing to secondary school teachers. It provides a forum that allows classroom teachers to share their mathematics from their work with students, their classroom investigations and products, and their other experiences. Delving Deeper is a regular department of Mathematics Teacher.
The Nature And Nurture Of Intuition, Thomas Q. Sibley
The Nature And Nurture Of Intuition, Thomas Q. Sibley
Forum Lectures
Are people just innately good at mathematics or not? My teaching experience suggests mathematical ability is not just fate: Students develop their mathematical abilities by doing mathematics. In particular we discuss geometric intuition, its connection with geometric reasoning and the possibility of developing them, using examples to get the listeners actively thinking about their own geometric thinking.

Bioelectrical Impedance Analysis As A Laboratory Activity: At The Interface Of Physics And The Body, Elliot Mylott, Ellynne Marie Kutschera, Ralf Widenhorn
Physics Faculty Publications and Presentations
We present a novel laboratory activity on RC circuits aimed at introductory physics students in life-science majors. The activity teaches principles of RC circuits by connecting ac-circuit concepts to bioelectrical impedance analysis (BIA) using a custom-designed educational BIA device. The activity shows how a BIA device works and how current, voltage, and impedance measurements relate to bioelectrical characteristics of the human body. From this, useful observations can be made including body water, fat-free mass, and body fat percentage. The laboratory is engaging to pre-health and life-science students, as well as engineering students who are given the opportunity to observe electrical …
What Is So Negative About Negative Exponents?, Geoffrey D. Dietz
What Is So Negative About Negative Exponents?, Geoffrey D. Dietz
Journal of Humanistic Mathematics
While teaching college-level mathematics (from College Algebra to Calculus to Abstract Algebra), I have observed that students are often uncomfortable using negative exponents in calculations. I believe the fault partially lies in the manner in which negative exponents are taught in Algebra 1 or Algebra 2 courses, especially in rigid instructions always to write answers using only positive exponents. After reviewing a sample of algebra texts used in the United States over the last two centuries, it appears that while attitudes toward negative exponents have varied from author to author over time, the current trend is to declare explicitly that …
Benjamin Banneker's Original Handwritten Document: Observations And Study Of The Cicada, Janet E. Barber, Asamoah Nkwanta
Benjamin Banneker's Original Handwritten Document: Observations And Study Of The Cicada, Janet E. Barber, Asamoah Nkwanta
Journal of Humanistic Mathematics
Benjamin Banneker, farmer, mathematician, astronomer, and scientist, is known for his mathematical puzzles, ephemeris calculations, almanacs, his wooden clock, land surveying work, and famous letter on human rights. However, as a naturalist, his scientific and systematic observations of the cicadas are less known. In this paper we publicize Banneker’s naturalistic study of the seventeen-year periodic cycle of the cicada and make available the original handwritten document of his observations. We also introduce the audience of this journal to an intriguing natural problem involving prime numbers.
Grading By Response Category: A Simple Method For Providing Students With Meaningful Feedback On Exams In Large Courses, Cassandra Paul, Wendell Potter, Brenda Weiss
Grading By Response Category: A Simple Method For Providing Students With Meaningful Feedback On Exams In Large Courses, Cassandra Paul, Wendell Potter, Brenda Weiss
Faculty Publications
As instructors, we want our students to develop a deep understanding of course material, and feedback is essential in their sense-making process. Providing effective individualized feedback to students in large courses is especially difficult. While researcherssuggest,1 and many instructors of large courses are,2,3incorporating interactive techniques that allow peer feedback, studies have shown that it's important for students to also have direct feedback from the instructor.4 Since the requirement for individualized feedback is difficult to meet during class time in large courses, providing effective feedback on exams and quizzes takes on added importance. Some instructors choose to …
Developing Transfer Skills In A Biochemistry Class, Jeong V. Choe
Developing Transfer Skills In A Biochemistry Class, Jeong V. Choe
Faculty Publications & Research
Students seem to struggle with transferring prior knowledge if the new problem they are given is in a different form from the way they learned the material. The process of transfer can be identified by four components: 1) recognizing the similarity between the old and new contexts; 2) identifying the potential of a certain skill or concept that has worked in the past, to give solutions to new problematic situations; 3) mental testing of the application of the potential solution; and 4) an attempt to apply the skill or concept to a new context (Georghiades 2000). These four components are …

Partnering With Principals Through Formal And Informal Professional Development, V. Bohidar
Journal of Mathematics and Science: Collaborative Explorations
Mathematics Specialists and administrators need to define what they should see students and teachers doing in classrooms that promote proficiency and understanding in mathematics. Formal, divisionwide professional development on this topic can quickly guide and inform a large group of administrators in one setting. However, potentially more powerful professional development can occur on a small scale one building at a time through mathematics department learning walks.

Principal And Mathematics Coaches' Journey To Improve Mathematics Learning, R. Cox
Principal And Mathematics Coaches' Journey To Improve Mathematics Learning, R. Cox
Journal of Mathematics and Science: Collaborative Explorations
My educational career path began as an elementary school teacher, then as an assistant principal, and now as a principal. With the educational experiences that I had at each level of my career, I was certain I would be able to handle an increase in the mathematical rigor presented to our students through the new Mathematics Standards of Learning for Virginia Public Schools (SOL) [1]. I found that, yes, I was able to understand the rigor. However, I found the challenge was providing the needed assistance to bring about results that would ultimately help our teachers and students be successful. …

An African-Centered Approach To Land Education, Salvotore Engel-Dimauro, Karanja Keita Carroll
An African-Centered Approach To Land Education, Salvotore Engel-Dimauro, Karanja Keita Carroll
Publications and Research
Approaches to environmental education which are engaging with place and critical pedagogy have not yet broadly engaged with the African world and insights from Africana Studies and Geography. An African-centered approach facilitates people's reconnection to places and ecosystems in ways that do not reduce places to objects of conquest and things to be exploited for profitability and individual gain. Such an approach offers effective critiques of settler coloniser perspectives on the environment and deeper understandings of the relationship between worldview and ecologically sensitised education. Through examples from Africana Studies and Geography, this article provides an introduction to how an African-centered …

Biology Faculty Publications
Proficiency in mathematics and statistics is essential to modern ecological science, yet few studies have assessed the level of quantitative training received by ecologists. To do so, we conducted an online survey. The 937 respondents were mostly early-career scientists who studied biology as undergraduates. We found a clear self-perceived lack of quantitative training: 75% were not satisfied with their understanding of mathematical models; 75% felt that the level of mathematics was “too low” in their ecology classes; 90% wanted more mathematics classes for ecologists; and 95% more statistics classes. Respondents thought that 30% of classes in ecology-related degrees should be …
Synchronous Rotation In The Eclipsing Binary 68 Herculis Inferred From Doppler Shifts In Its Spectrum And Light Curve Modeling, Kenneth W. Mclaughlin, Janak Panthi
Synchronous Rotation In The Eclipsing Binary 68 Herculis Inferred From Doppler Shifts In Its Spectrum And Light Curve Modeling, Kenneth W. Mclaughlin, Janak Panthi
Journal of the Iowa Academy of Science: JIAS
Our differential photometry of the eclipsing binary 68 Herculis through V- and R-filters shows periodic minima consistent with a previously established period. As a function of its orbital motion, we report spectra over a limited wavelength range encompassing H-alpha 656.3 nm and helium 667.8 nm lines. Doppler shifts of both stars were resolved in H-alpha, while only the more massive star rendered the helium line with Doppler shifts that agree with the radial velocity we derive for it from the H-alpha profile. Sinusoidal curve-fits to the orbital dependence of the radial velocities imply circular orbits for both components, with amplitudes …
