Detection Of Psilocybin Mushroom Analogs In Chocolate: Incorporating Current Events Into The Undergraduate Teaching Laboratory, Brandon Huskins, Christopher Dockery

Faculty Articles

In this experiment, tryptamine is used as a psilocin analog and is dispersed onto a Fisher brand cellulose laboratory sponge to simulate dehydrated mushrooms. The resulting “mushroom” material is ground, molded into chocolate, and presented to student groups for real-world and applied analyses. Students isolate the tryptamine from the chocolate using their knowledge of drug chemistry, solubility, pH, extractions, etc. Qualitative analysis is conducted by comparison to standards (Thin Layer Chromatography or Gas Chromatography) and quantitative analysis is conducted by Gas Chromatography using the method of internal standards.

Deliberation Versus Dispute: The Impact Of Argumentative Discourse Goals On Learning And Reasoning In The Science Classroom, Mark Felton, Merce Garcia-Mila, Sandra Gilabert

Faculty Publications

Researchers in science education have converged on the view that argumentation can be an effective intervention for promoting knowledge construction in science classrooms.However, the impact of such interventions may be mediated by individuals’ task goals while arguing. In argumentative discourse, one can distinguish two overlapping but distinct kinds of activity: dispute and deliberation. In dispute the goal is to defend a conclusion by undermining alternatives, whereas in deliberation the goal is to arrive at a conclusion by contrasting alternatives. In this study, we examine the impact of these discourse goals on both content learning and argument quality in science.

Students In Rural Schools Have Limited Access To Advanced Mathematics Courses, Suzanne E. Graham

Carsey School of Public Policy

This Carsey brief reveals that students in rural areas and small towns have less access to higher-level mathematics courses than students in urban settings, which results in serious educational consequences, including lower scores on assessment tests and fewer qualified students entering science, technology, engineering, and mathematics (STEM) job pipelines.

Undergraduate Engineering Students' Understanding Of Heat, Temperature, And Radiation, Katharyn E.K. Nottis, Michael Prince, Margot Vigeant, Sarah Nelson, Kathryn Hartsock

NERA Conference Proceedings 2009

Difficulty understanding heat and temperature concepts has been recognized in engineering education. Confusion has been shown to persist after instruction. The purpose of this study was to determine whether undergraduate engineering students’ knowledge of four heat transfer concept areas significantly changed with instruction and whether this varied by major and GPA. Two hundred twenty-eight undergraduate engineering students from six institutions were assessed prior to and after instruction. Results showed significant improvement in most concept areas but mean scores were below mastery. Previously documented misconceptions persisted after instruction. Significant differences were found by major and GPA. Suggestions for future research provided.

The Effect Of Mathematics Self-Efficacy On Mathematics Achievement Of High School Students, Xing Liu, Hari Koirala

NERA Conference Proceedings 2009

The purpose of this study was to investigate the relationship between mathematics self-efficacy and mathematics achievement of high school sophomores across the United States. Using regression analysis for complex sample survey data from the Educational Longitudinal Study of 2002 (ELS, 2002) (n = 11726), the current study indicated that mathematics self-efficacy and mathematics achievement were positively related, and mathematics self-efficacy was a significantly positive predictor of mathematics achievement. Results from this study, which is generalizable to the population of approximately three million high school sophomores, suggest that mathematics self-efficacy of high school students should be promoted to increase their achievement.

A Computational Study Of The Effects Of Temperature Variation On Turtle Egg Development, Sex Determination, And Population Dynamics, Amy L. Parrott

Department of Mathematics: Dissertations, Theses, and Student Research

Climate change and its effects on ecosystems is a major concern. For certain animal species, especially those that exhibit what is known as temperature-dependent sex determination (TSD), temperature variations pose a possibly serious threat (Valenzuela and Lance, 2004). In these species, temperature, and not chromosomes, determines the sex of the animal (Valenzuela and Lance, 2004). It is conceivable therefore, that if the temperature changes to favor only one sex, then dire consequences for their populations could occur. In this dissertation, we examine possible effects that climate change may have upon Painted Turtles (Chrysemys picta), a species with TSD. We investigate …

Fan Cohomology And Equivariant Chow Rings Of Toric Varieties, Mu-Wan Huang

Department of Mathematics: Dissertations, Theses, and Student Research

Toric varieties are varieties equipped with a torus action and constructed from cones and fans. In the joint work with Suanne Au and Mark E. Walker, we prove that the equivariant K-theory of an affine toric variety constructed from a cone can be identified with a group ring determined by the cone. When a toric variety X(Δ) is smooth, we interpret equivariant K-groups as presheaves on the associated fan space Δ. Relating the sheaf cohomology groups to equivariant K-groups via a spectral sequence, we provide another proof of a theorem of Vezzosi and Vistoli: equivariant K …

Mathematical Communication Through Written And Oral Expression, Brandee Wilson

Action Research Projects

In this action research study of my classroom of sixth grade mathematics, I investigated the use of communication of mathematics through both written and oral expression. Giving my students the opportunity to communicate mathematics both in writing and orally helped to deepen the students’ understanding of mathematics. The students’ levels of comprehension were increased when they were presented with a variety of instructional methods. Through discussion and reflection the students were able to find methods that worked best for them and their learning ability. Students’ understanding increased from probing questions that made the students reflect and re-evaluate their solutions. This …

Written Communication In A Sixth-Grade Mathematics Classroom, Mary Schneider

Action Research Projects

In this action research study of my sixth grade mathematics classroom, I investigated what happened to students’ mathematical achievement when they had increased practice on written explanations to problems. I wanted to see if writing out solutions to problems helped them overall in daily mathematics. By using specific mathematic vocabulary more frequently and deliberately during my instruction, I wanted to investigate whether students would correctly use specific math vocabulary in their written explanations. I also increased my expectations of the students’ written explanations throughout the research project. I wanted to determine whether students would try to meet or even exceed …

Reviewing, Rethinking And Revising Homework Expectations In A Seventh Grade Math Class, Marilyn Hein

Departament of Teaching, Learning, and Teacher Education: Master's of Arts in Teaching, Summative Projects

In this action research study of my seventh grade mathematics class, I investigated whether de-emphasizing homework assignments as daily grades while stressing them as daily practice encouraged students to focus more on the learning rather than the daily grade. As part of this study, I also looked at how this change in homework expectations affected my daily teaching. I discovered that having students keep notes, examples, practice problems and homework assignments in a notebook helped them concentrate more on the process of getting answers and why they may of had an incorrect answer. Students were more likely to discuss with …

Problems With Problem Solving: Assessing Written Solutions Of Mathematical Habits Of Mind Problems, Ali Arndt

This paper explores a study of sixth grade mathematics students in a middle school setting. I investigated the effects of assigning Habits of Mind problems related to the curriculum, district standards and objectives to increase problem-solving opportunities and skills. I discovered integrating problem solving into the given curriculum allowed students to make connections to math in an opportune way that evoked communication on paper, interactions with partners or small groups, and presentations of solutions to the large group. Using the challenging Habits of Mind problems deliberately chosen to match specific content objectives within my district at the sixth grade level …
