The Effects Of Tinkerability On Novice Programming Skill Acquisition, Tian Luo

STEMPS Faculty Publications

This paper reports on an exploratory study which used a graphical programming environment, Scratch, to facilitate the comprehension of a scripting programming language, ActionScript. Online survey questionnaires were distributed to 34 enrolled students, in a graduate level programming course with a 70% response rate. Findings indicated that Scratch contributed to the understanding of basic programming concepts such as event handling, sequential, and conditional statement but it was less helpful in assisting students’ understanding of more abstract concepts such as variables. This study also suggests that students’ learning style preference and proficiency with programming also make a difference in their perception …

On The Betti Number Of Differential Modules, Justin Devries

Department of Mathematics: Dissertations, Theses, and Student Research

Let R = k[x₁, ..., x_n] with k a field. A multi-graded differential R-module is a multi-graded R-module D with an endomorphism d such that d² = 0. This dissertation establishes a lower bound on the rank of such a differential module when the underlying R-module is free. We define the Betti number of a differential module and use it to show that when the homology ker d/im d of D is non-zero and finite dimensional over k then there is an inequality rank_R D ≥ 2ⁿ. This …

The Influence Of Virtual Manipulatives On Second Grader's Acquisition Of Place Value Concepts, Kay Jolicoeur

Electronic Theses and Dissertations

The purpose of this study was to examine my own practice of teaching place value and the influence virtual manipulatives had, in addition to physical manipulatives, on place value understanding of my second grade students. I wanted to see how adding a base-ten computer applet might better meet the needs of all learners while also meeting the needs of today’s technological classroom. Through this study, I found that both physical and virtual manipulatives helped students acquire place value concepts. I found that virtual manipulatives had features that engaged students in a way that increased their mathematical language, increased students’ ability …

Prospective Teachers' Use Of Representations In Solving Statistical Tasks With Dynamic Statistical Software, Hollylynne Lee, Shannon O. Driskell, Suzanne R. Harper, Keith R. Leatham, Gladis Kersaint, Robin L. Angotti

Mathematics Faculty Publications

This study examined a random stratified sample (n=62) of prospective teachers' work across eight institutions on three tasks that utilized dynamic statistical software. Our work was guided by considering how teachers may utilize their statistical knowledge and technological statistical knowledge to engage in cycles of investigation. Although teachers did not tend to take full advantage of dynamic linking capabilities, they utilized a large variety of graphical representations and often added statistical measures or other augmentations to graphs as part of their analysis.

Personal And Professional Numeracy: A Unit For Pre-Service Teachers At The University Of Tasmania, Jane M. Watson

Numeracy

This paper addresses issues associated with the development of a unit preparing pre-service teachers to be quantitatively literate in three respects. These issues surround (i) the need to be aware of numeracy demands across the curriculum, (ii) the need to model numerate behavior in all interactions of teachers, and (iii) the need to be able to interpret and use system data provided from local and national testing programs. The context for the unit described is Australia, where a national testing program for literacy and numeracy requires teachers to analyze extensive data on their students, a national curriculum requires teachers of …

Go Figure: Calculus Students' Use Of Figures And Graphs In Technical Report Writing, Thomas J. Pfaff, Michael Rogers, Ali Erkan, Jason G. Hamilton

Numeracy

Understanding how to read and use graphs to communicate scientific and mathematical information is critical for STEM majors, as well as an important part of quantitative literacy. Our study suggests that first-semester calculus students do not know how to use graphs in a technical report without explicit instruction. Although not a surprising result, it leaves us wondering about when such skills are developed, and if calculus I is a place to start. Our work is now exploring the potential benefit on students' use of graphs by having them formally evaluate other students' reports.

The ten scholarly papers in Sex, Drugs and Body Counts explore the generation and propagation of numbers that drive policy decisions in the U.S. government regarding human trafficking, drug trade, and armed conflict (including the war on terror). Each of these papers, written by different authors, provides an illuminating insight into how some of the numbers we hear or read in the news are derived. …

An Examination Of Mathematical Knowledge For Teaching In Professional Development Settings, Shannon Harmon

Electronic Theses and Dissertations

Researchers have laid the foundation for what mathematics teachers need to know, a construct referred to as Mathematical Knowledge for Teaching (Ball, Thames, & Phelps, 2008). There is, however, a lack of robust research regarding how Mathematical Knowledge for Teaching (MKT) is developed within professional development settings. The purpose of this qualitative research study, therefore, was to examine how different foci of professional development revealed different domains of MKT. In the immersion setting, the professional development focused on engaging teachers in discourse surrounding teachers' completion of mathematical tasks. In the practice-based setting, the professional development focused on engaging teachers in …

Many different areas of influence could affect a student's decision to major in physics. The first phase of this study addresses all of the potential areas of influence identified from the literature. The goal was to identify common influences that might be used to increase students' interest in majoring in physics. Subjects (N=35) from the first phase were recruited …

An Exploration Of Worldview And Conceptions Of Nature Of Science Among Science Teachers At A Private Christian High School, Kara M. Kits

Dissertations

Both worldview and conceptions of nature of science (NOS) are important components in teaching and learning science. However, few empirical studies have examined the interplay between both of these components for teachers or students. Therefore, this study examines the possible relationship between worldview and conceptions of nature of science for secondary science teachers who currently teach at a Christian school.

Qualitative methodologies developed a rich description of the worldview beliefs and conceptions of NOS for teachers in this study. Eight secondary science teachers employed at a private Christian school participated in the study. A Views of Nature of Science (VNOS) …

Impulse-Momentum Diagrams, David Rosengrant

Faculty Articles

Multiple representations are a valuable tool to help students learn and understand physics concepts. Furthermore, representations help students learn how to think and act like real scientists. These representations include: pictures, free‐body diagrams, energy bar charts, electrical circuits, and, more recently, computer simulations and animations. However, instructors have limited choices when they want to help their students understand impulse and momentum. One of the only available options is the impulse‐momentum bar chart. The bar charts can effectively show the magnitude of the momentum as well as help students understand conservation of momentum, but they do not easily show the actual …

Attempting To Improve Standardized Test Results Using Study Islands' Web-Based Mastery Program , Paul J. Dube'

Dissertations, Master's Theses and Master's Reports - Open

State standardized testing has always been a tool to measure a school’s performance and to help evaluate school curriculum. However, with the school of choice legislation in 1992, the MEAP test became a measuring stick to grade schools by and a major tool in attracting school of choice students. Now, declining enrollment and a state budget struggling to stay out of the red have made school of choice students more important than ever before. MEAP scores have become the deciding factor in some cases.

For the past five years, the Hancock Middle School staff has been working hard to improve …

The Impact Of Student Created Slowmation On The Teaching And Learning Of Primary Science, Jeffrey Brown

Theses: Doctorates and Masters

Current research indicates that although innovations in science teaching are having a positive impact on science education in many Australian schools, national and international assessments show that student achievement is not improving (Hackling & Prain, 2008; Thomson, Wernet, Underwood, & Nicholas, 2008). Furthermore, there is little or no increase in the number of students choosing science as a post-compulsory study option or as a career path. There remains a need to further develop innovative teaching methods that promote the development of students‟ scientific literacy, engenders a joy of science learning through student engagement and encourages a desire to pursue further …
