Active Learning In The Science Classroom, Amber Mathias

Honors Projects

This study focused on at active learning and how it affects student attitude and achievement in college level biology courses. A Biology Attitude Survey was administered at the beginning and middle of the semester to determine if student’s attitude towards biology improved from the active learning setting. The student’s attitude was also assessed from a classroom format survey containing questions about the benefits of undergraduate Learning Assistants and the active learning classroom format. These attitudinal measures were then compared with student’s achievement in biology by looking at their midterm grade, pre-test and post-test assessment scores. The ANOVA revealed that students …

Student Voices On High School Mathematics Teaching And Learning: College Student Voices On Teacher Behaviors And Actions Impacting High School Mathematics Achievement, Elizabeth Anne Crane

Online Theses and Dissertations

According to the national Assessment of Educational Progress the national trend in mathematics achievement has not significantly changed from 1973 through 2012 for 17 year olds (National Center for Educational statistics, 2014). Student beliefs about mathematics learning are an important factor in determining the student's math achievement (Woodward, 2004). This qualitative dissertation explores college student perceptions of effective mathematics teaching and learning at the secondary level. Interview participants who are early in their college program were recruited from math classes at a southeastern university. Study participants reinforced the literature that knowing both the how and the why of mathematics is …

One honors class and two standard classes were randomly selected as the treatment groups receiving CRA instruction. The other three classes learned through abstract explicit instruction. Each class learned two new mathematical concepts, domain and range of quadratic functions and transformations of quadratic functions, through the selected method of instruction. At the end of instruction, …

Gene Expression Of Components Of The Insulin/Insulin-Like Signaling Pathway In Response To Heat Stress In The Garter Snake, Thamnophis Elegans, Tonia S. Schwartz, Anne M. Bronikowski

Journal of the Iowa Academy of Science: JIAS

The insulin/insulin-like signaling (IIS) pathway is an evolutionary conserved molecular signaling pathway that regulates growth, reproduction, stress resistance, and longevity in response to nutrition and external stress. While the constituents of this pathway and their functions are relatively well understood in laboratory model animals, they have not been explored in many other organisms, with notable exceptions in the fisheries literature. We tested for the gene expression of four key components of this pathway in the garter snake (Thamnophis elegans) liver, and determine how the transcription of these components responds to heat stress. We found that the two insulin-like …

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 …

Improved Functional Prediction Of Hypothetical Proteins From Listeria Monocytogenes 08-5578, Michael J. Lagier, Brittany Bowman, Kelsey Brend, Katherine Hobbs, Michael Foggia, Mark Mcdaniel

Journal of the Iowa Academy of Science: JIAS

Listeria monocytogenes is a foodborne human pathogen responsible for listerosis. The genomes of several L. monocytogenes strains have been recently sequenced. The genome of L. monocytogenes 08-5578, which was in part responsible for a significant listerosis outbreak in 2008, contains an unexpectedly high percentage of protein-encoding genes (1,927 out of 3,161; 60.96%) autonomously annotated as hypothetical proteins. The aim of this study was to test whether a manual annotation strategy could be used to assign more meaningful functional names to the hypothetical proteins of 08-5578. A holistic, manual gene annotation strategy that utilized sequence homology, cellular localization predictions, structure-based evidence, …

The Role Of An Urban Tallgrass Prairie Remnant In Conservation: A Case Study In Central Iowa (Usa), Jimmie D. Thompson, Deborah Q. Lewis, William R. Norris

Journal of the Iowa Academy of Science: JIAS

Although more than 85% of Iowa (USA) was covered by tallgrass prairie at the time of settlement by Europeans in the early 19th century, less than 0.1% remains. The Richard W. Pohl State Preserve at Ames (IA) High School, surrounded on three sides by structures, roads, and other development, protects 4 ha of tallgrass prairie. The preserve, commonly referred to as Ames High Prairie (AHP), was grazed but never plowed under private ownership until its acquisition by the Ames School District in 1959.

Although considered for development as a parking lot or football field in the 1960s, the residents of …

Chemical Reactions As Petite Rendezvous: The Use Of Metaphor In Materials Science Education, Vuk Uskoković

Pharmacy Faculty Articles and Research

Every time we communicate our science, we are involuntarily involved in an educational activity, affecting the listeners’ methodology and motivation. In a beautiful metaphor, late Nobel Laureate, Richard E. Smalley compared interacting atoms and molecules to boys and girls falling in love. Elaborated and exemplified with a couple of entertaining analogies in this discourse is the effectiveness of the use of metaphors in illustrating scientific concepts to both scientific novices and peers. Human brain has been considered to be a complex neural circuitry for the computation of metaphors, which explains the naturalness of their usage, especially when solid arguments could …

Pre-Service Teachers’ Use Of Visualizations In The Science Classroom: A Case Study, Brooke A. Whitworth, Jennifer L. Chiu

Publications

Scientific visualizations of phenomena can enhance the way learners understand scientific concepts (Honey & Hilton, 2011). Scientific concepts can be abstract and difficult for students to understand and visualizations can help make these abstract concepts more concrete for students. For example, chemistry students often struggle with understanding how atoms bond since they cannot directly see atoms. Using a visualization to show students how the electrons are shared or transferred can help students understand these abstract concepts. In addition, many visualizations are freely available online and can be a key element to maintain quality science instruction with limited resources.

Kinesthetic Activities For The Classroom, Elliot E. Mylott, Justin C. Dunlap, Lester Lampert, Ralf Widenhorn

Physics Faculty Publications and Presentations

Educators have found that kinesthetic involvement in an experiment or demonstration can engage students in a powerful way. With that as our goal, we developed three activities that allow students to connect with and quantitatively explore key physics principles from mechanics with three fun physical challenges. By presenting these activities as competitions, we can challenge students to use what they know about the relevant physics to improve their performance and beat their own score or those of other students. Each activity uses an original, real-time data collecting program that offers students and educators a simple, clear method to demonstrate various …

The Collaboration Of A Principal And A Mathematics Specialist, S. Garthwaite, P. Granada

Journal of Mathematics and Science: Collaborative Explorations

This article describes the importance of the collaboration between the principal, Patty Granada, and the Mathematics Specialist, Susan Garthwaite, in fostering a highly functioning mathematics program. While many aspects of the collaboration as facilitators for a mathematics program are logical, the "messy" aspects provide greater challenges. Through continued collaboration, they have come to embrace the "messiness" which has contributed to an awareness of similar belief systems in their roles. These beliefs include openness to learning and a sincere commitment to bringing out the best in students and teachers. The principal and the Mathematics Specialist share their continued journey in this …
