Using survey research, we sought to measure whether the relevance of students' course experiences influenced their expectancies and value and whether those attitudes predicted whether students …

A Quantitative Analysis Of Whether Elementary Teachers’ Science Kit Usage And Beliefs Can Predict State Science Assessment Scores, Tony E. Rice

Dissertations

The purpose of this survey was to describe and analyze the perceptions of elementary school teachers’ in a Midwestern state concerning their use of a science kit program, including to what extent a school’s state science assessment scores can be predicated from the level of science kit usage.

Prior research indicates that elementary school teachers lack the confidence in teaching science primarily because of their weak undergraduate training in inquiry-based instruction and the lack of a strong science background. Authors such as Dickerson et al. (2006) and Riggs and Enochs (2006) argued that science kits and the materials included in …

Structural Behavior Of Nbsexte2-X Superconductors Under High Pressure, Vahe Mkrtchyan

UNLV Theses, Dissertations, Professional Papers, and Capstones

Niobium chalcogenide compounds have recently gained a great deal of interest due to the fact that a superconducting phase coexists with the charge density wave state (CDW), as well as their potential for numerous applications. Two superconducting compositions, NbSexTe2-x (x=2, 1.5) were prepared by solid state route using high purity Nb, Se, and Te powders. Powder X-ray diffraction patterns collected at ambient conditions for NbSe2 and NbSe1.5Te0.5 showed a single phase with hexagonal crystal structure, with space group P63mmc. High-pressure X-ray diffraction measurements were performed at the Advanced Photon Source at Argonne National Laboratory to investigate structural stability up to …

A Truly Beautiful Theorem: Demonstrating The Magnificence Of The Fundamental Theorem Of Calculus, Dan Mcquillan, Darlene M. Olsen

Journal of Humanistic Mathematics

In standard treatments of calculus, the Fundamental Theorem of Calculus is often presented as a computational method to evaluate definite integrals, with such powerful utility that one is tempted to overlook its beauty. To improve students' appreciation for the first part of the Fundamental Theorem of Calculus, we suggest a few classroom examples focusing on the accumulation function, to be introduced early and often throughout an introductory calculus course. These examples are small enough that they would not necessarily result in changes to a typical course schedule; yet we believe their contribution to student understanding can be significant. Furthermore, such …

Journal of Humanistic Mathematics

This study investigates student success in an online introductory statistics class. We examine the impact of several variables: amount of time that a student watches instructor-made videos (IMV), the nature of communication between the student and the instructor, and the amount of time spent on completing the online assignments and exams on student grades in an introductory level online statistics course. Findings suggest that IMVs of short dur ation, the subject- related communication between the student and the instructor, and homework completion time have significant association with student performance. Though the average time spent on online exams does not show …

Bringing Students Back To Mathematics: Classroom Knowledge And Motivation, Giang-Nguyen T. Nguyen, Joel B. Goodin

Journal of Humanistic Mathematics

This paper reports part of a larger research study that investigated how teachers motivate students to learn mathematics at the college level. Findings from the study indicated that teachers have the power to influence and reinvigorate students who had given up learning mathematics. In the framework of Self-Determination Theory (SDT), the researchers analyzed five students’ motivational levels based on intrinsic and extrinsic motivation to see how each student was motivated by their teacher. Findings from the study could provide some directions for future research on students’ motivation to learn mathematics.

Journal of Humanistic Mathematics

A college professor, who is highly skeptical of change, but sensing a need for teaching in a more inspiring and engaging way, implements an inquiry-based learning (IBL) approach to teaching the history of mathematics. The first author (Matthews) worked with an experienced IBL colleague mentor (Hodge) on the course. Some student data was collected to document the effects of the class on the students. The approach taken for the course is described in detail including how the students of the course learned about and used IBL in key peer-to-peer teaching about historical mathematics (with a primary focus on the mathemat- …

Humanizing Mathematics Through Ethnomodelling, Milton Rosa, Daniel Clark Orey

Journal of Humanistic Mathematics

Ethnomathematical techniques and modelling tools allow us to examine systems taken from the real world and offer us insight into forms of mathematics performed in holistic contexts [3]. A pedagogical approach that connects a diversity of cultural forms of mathematics can be implemented by the use of ethnomodelling, a process of translation and elaboration of problems and questions taken from non-academic systems. Here, we offer examples of studies conducted in Brazil and in the United States that explore this pedagogical approach. Our goal is to broaden the discussion of possibilities for ethnomathematics and associated ethnomodelling perspectives that respect the …

Becoming A Scientist: Using First-Year Undergraduate Science Courses To Promote Identification With Science Disciplines, Chloe Ruff, Brett D. Jones

Education Faculty Publications

In this qualitative study, we examined how two professors (a physicist and biochemist) of first year college students perceived their students’ development of identification in biochemistry or physics and how they actively supported this development. The professors described students who entered college with different levels of domain identification and different expectations for their college science experience depending upon whether they were in a biochemistry or physics major. Although neither professor was familiar with research related to the concept of domain identification, their beliefs about their students’ identification and academic support strategies generally aligned with the Osborne and Jones (2011) model …

Using A Computer Science-Based Board Game To Develop Preschoolers' Mathematics, Ryan Andrew Nivens, Rosemary Geiken

ETSU Faculty Works

There is a critical need to teach computer science (CS) in order to assure that our nation remains competitive globally [6]. CS is a new basic skill necessary for economic opportunity [6] but is rarely taught before age 6 and only using electronic devices [1]. This presents a challenge for those concerned with “screen time” inherent in electronic devices [2] and for children in poverty with little access to electronic devices [3]. Coding, creating a series of commands that a computer carries out, is a component of CS and can be introduced as early as preschool age and results in …
