An Examination Of Laboratory Activities For Elements Of Inquiry In Arkansas Secondary Biology Courses, Michele E. Snyder

Theses and Dissertations

In the last 20 years, several panels recommended improving science teaching by incorporating inquiry approaches into K-12 classrooms. These panels assert that inquiry improves student learning in large part by giving students ownership. However, many teachers still present labs that simply call for students to follow written directions. This cookbook approach is the antithesis of inquiry. To take a "snap shot" of biology teaching, I surveyed Arkansas biology teachers to 1) determine teachers' qualifications, 2) assess the labs that they considered their "best" via a rubric that assesses inquiry activities, and 3) discover the reasons teachers valued certain labs. The …

The study of the history of discoveries and insights that we have gained through the development of astrophysics and cosmology provides course options for students to use to explore …

Matlab Based Algorithm To Find The Remaining State Of Charge, Ishrat Khatoon, Bhaskar Saha, Kai Goebe

STAR Program Research Presentations

Li-ion batteries are one of the most common rechargeable batteries used in portable electronics, electric vehicles, military operations and aerospace applications such as electric air-crafts, spacecrafts, space rovers, robots, etc. Failure of these batteries could lead to reduced performance, operational impairment and even catastrophic failure, especially in aerospace systems. Monitoring the remaining state of charge (RSOC) of these batteries would greatly improve the reliability of the systems powered by them and will ultimately lengthen their lifetimes. NASA's Mars Global Surveyor spacecraft was lost due to battery failure. Hence, it is very important to find the RSOC of the batteries in …

Section 2 describes the goals of teaching mathematics and argues that a practical orientation should be the focus of mathematics teaching in the compulsory years, and outlines …

Incorporating Case Studies Into An Undergraduate Genetics Course, Marlene Murray

Faculty Publications

Genetics is considered one of the most challenging courses in the biology curricula at both the secondary and post secondary levels. Case based teaching has been shown to improve student perception and performance outcomes in both non-science and science courses. Thus in an effort to improve outcomes, case studies were integrated into an undergraduate genetics course as a supplement to lecture and replacement to recitation. Student perception and performance when case studies were used was compared to two previous years before the incorporation of case studies. Student course evaluations, pre and post surveys of student knowledge, and exam scores indicated …

Changing Perceptions Of Science In Undergraduate Students: A Mixed Methods Case Study, Cindy S. Larson-Miller

Department of Teaching, Learning, and Teacher Education: Theses and Other Student Research

The purpose of this bounded single-case study was to explore the understanding of the nature and process of science for undergraduate students at the University of Nebraska-Lincoln (UNL). The study investigated one professor’s methodology to explicitly teach undergraduate students about the nature and process of science, and documented their understanding and perception of science, both pre- and post-course.

Using a mixed method approach, data were collected to provide a better understanding of teaching the nature and process of science. Three main types of data were analyzed: the process of science (TPOS) assessment; survey questions, and the module curriculum.

Investigating Macroscopic, Submicroscopic, And Symbolic Connections In A College-Level General Chemistry Laboratory, Felicia Culver Thadison

Dissertations

Explanations of chemical phenomena rely on understanding the behavior of submicroscopic particles. Because this level is “invisible,” it is described using symbols such as models, diagrams and equations. For this reason, students often view chemistry as a “difficult” subject. The laboratory offers a unique opportunity for the students to experience chemistry macroscopically as well as symbolically. The purpose of this investigation was to determine how chemistry lab students explained chemical phenomenon on the macroscopic, submicroscopic, and representational/symbolic level. The participants were undergraduate students enrolled in an introductory level general chemistry lab course. Students’ background information (gender, the number of previous …

Factors That Contribute To Persistence And Retention Of Underrepresented Minority Undergraduate Students In Science, Technology, Engineering, And Mathematics (Stem), Sidney Kirk Mitchell

Dissertations

The objective of this research was to identify specific factors that contribute to underrepresented minority (African American, Hispanic, Native American) undergraduate students‟ success in STEM disciplines at a regional university during the 2007-2010 timeframe. As more underrepresented minority (URM) students complete STEM degrees, many will possess the skills to become part of the domestic human capital needed to meet U. S. workforce demands and enhance the nation‟s STEM innovation. According to Burke and Mattis (2007), the lack of URM students in STEM education and in the workforce is one of the major contributors to STEM shortages in the United States. …

Investigating The Effects Of Addition With Regrouping Strategy Instruction Among Elementary Students With Learning Disabilities, Christi Miller Carmack

UNLV Theses, Dissertations, Professional Papers, and Capstones

Many students, specifically those with learning disabilities, struggle to master foundational computation skills such as addition with regrouping. With this in mind, the purpose of this research was to examine the effects of strategy instruction that involved the use of the concrete-representational-abstract teaching sequence on the addition with regrouping computation and word problem-solving skills of students with learning disabilities. This study involved the use of a multiple probe across participants design with two replications. The participants included nine second through sixth graders who had been identified as having a learning disability and were demonstrating mathematics difficulties. There were three females …

Does The Use Of A Graphing Calculator Tutorial Affect The Attitudes, Achievement, And Calculator Ability Of Non-Mathematics Majors In A Calculus Course?, Kari Michelle Everett

Dissertations

The use of graphing calculators in a mathematics classroom is becoming more common place. Teaching with technology has allowed for advancements in the rapidity with which students learn and the degree to which they retain the material taught. As a result, teachers have time to delve more deeply into mathematical topics that might otherwise have merely been touched upon.

This study shows the effects of a graphing calculator tutorial for non-mathematics major students taking calculus as a required course. Qualitative methods were used in order to provide information about the types of students taking a calculus course for nonmathematic students. …

A Mathematician Weighs In On The Evolution Debate, Kris H. Green

Journal of Humanistic Mathematics

There are a variety of reasons underlying the lack of public acceptance for the theory of evolution in the United States. An overlooked cause is related to problems with the mathematics curriculum in the K-12 setting. In this essay, we examine this relationship and propose changes to the mathematics curriculum that could improve mathematical thinking while also providing a basis for understanding theories, like evolution, that are poorly understood.

On Doing Mathematics, Sue Vanhattum

Journal of Humanistic Mathematics

Covariant Representations Of C*-Dynamical Systems Involving Compact Groups, Firuz Kamalov

Department of Mathematics: Dissertations, Theses, and Student Research

Given a C*-dynamical system (A, G, σ) the crossed product C*-algebra A x _σG encodes the action of G on A. By the universal property of A x _σG there exists a one to one correspondence between the set all covariant representations of the system (A, G, σ) and the set of all *-representations of A x _σG. Therefore, the study of representations of A x _σG is equivalent to that of covariant representations of (A, G, σ).

We study induced covariant representations of systems involving compact groups. We prove that every irreducible (resp. factor) covariant …

How Student Positioning Can Lead To Failure In Inquiry-Based Classrooms, Kelly Beatrice Campbell

Theses and Dissertations

In an effort to improve mathematics instruction, I studied how the positions students choose or are pressed to take on can lead to failure in an inquiry-based classroom. Positioning refers to the temporary roles that a student or a teacher can place each other in or take on in a given classroom environment. Since positions are constructed and maintained by language use, I drew from positioning theory and discourse theory for my theoretical framework. From analyzing transcripts of classroom episodes and interviews with the teacher and a student, I identified common positions that the teacher and the student took on. …
