Tangible Teaching: The Effect Of Physical Modeling On Community College Students’ Understanding Of Conservation Of Matter, Erick T. Moffett

Dissertations

Students’ weak understanding of conservation of matter is well documented; however, there is a paucity of research that provides science educators with actual examples of empirically proven curricula employing physical modeling that can be used in the chemistry classroom to teach this fundamental concept. An intervention (three sequential physical modeling activities) was developed and evaluated. The intervention was administered to two sections of a General Chemistry I course at a community college in the southeastern United States, and pre-test/post-test data using a published instrument were collected to evaluate the physical model’s effectiveness in developing students’ understanding of conservation of matter …

The Effect Of An Historical Geology Course On Students’ Attitudes Towards Science And Their Knowledge Of Deep Time As A Threshold To Their Knowledge Of Evolution, Allan Nolan

Dissertations

In America there exists a conflict between a small group of its citizens and the concept of evolution. Researchers have studied this conflict and the ways in which teachers might approach educational methodologies that not only address evolution in a sensitive manner, but also remain legally acceptable.

This research was designed to address teaching evolution in the context of deep time – the concept that time is vast and that geology and biology operate in a timescale of hundreds of millions to billions of years. In previous peer-reviewed works, it has been stated that deep time acts as a threshold …

Computer-Based Instruction As A Form Of Differentiated Instruction In A Traditional, Teacher-Led, Low-Income, High School Biology Classroom, Cheryl Casey

Dissertations and Theses

In 2015 the U.S. continues to struggle with academic achievement in public schools. Average test scores from 15 year olds taking the Program for International Student Assessment placed the U.S. as 38th out of 71 countries (Drew Devlin, 2017). It is common to discuss elimination of the achievement gap as the single most effective way to improve the U.S.'s mediocre standing among the highest scoring countries in the world in primary and secondary student test scores (McGhee,2004; Flemming 2012). In the broadest sense of the term the "achievement gap" refers to the difference in academic success between different groups of …

Stem Pipeline For Students With Disabilities: From High School To Intentions To Major In Stem, Joshua Bittinger

Doctoral Dissertations

This dissertation examined the science, technology, engineering, and math (STEM) major declaration intentions of students with disabilities as they graduated high school and entered college. I used data from the High School Longitudinal Study of 2009 (HSLS:09) because data collection began in high school and followed students into college, facilitating research focusing on access. Before investigating major declaration intentions, I critiqued the definition and measurement of disability in the HSLS:09, drawing from survey research methods literature. The two subsequent analyses focused on psychological and structural components, respectively. My focus on psychological components drew from Eccles and colleagues’ (1983) expectancy-value framework. …

Exploring Math Education In China And Ontario, Tian Lan

Major Papers

As math education is one of the most vital subjects required in school and society in the 21st century (European Commission, 2011), the student’s math competence has the potential to influence the development of economic, political and social policies of their own country (Hanushek, Woessmann, Jamison, & Jamison, 2008). Students’ engagement in math is influenced by many factors. Many studies show that the students’ engagement in math may influenced by parents’ attitude toward math and other studies show that the gender stereotype may influence students’ engagement in math. In this paper, according to the expectancy-value theory, students’ engagement with math …

Principles Of Productivity Revealed From Secondary Mathematics Teachers' Discussions Around The Productiveness Of Teacher Moves In Response To Teachable Moments, Kylie Victoria Palsky

Theses and Dissertations

How do teachers talk about the productiveness of teacher's in-the-moment responses to student mathematical thinking? This is a question current research does not fully answer as most research on teacher moves is focused on what teacher moves researchers have noticed teachers do rather than on what teachers think about these teacher moves. To fill the gap in the research and to answer the question, a group of 13 teachers were given ten classroom situations to compare and contrast for productivity. I analyzed (a) the content of the teachers' discussions by drawing on Teacher Response Coding (TRC) language, and (b) the …

The Effect Of Choice Of Ipad-Delivered Math Independent Practice Of Elementary Grade Students With Attention-Deficit/Hyperactivity Characteristics, Nora A. Altaweel

Communication Disorders & Special Education Theses & Dissertations

A choice-making strategy is an antecedent control that has proven to be effective for students with problem behaviors. Because students with Attention-deficit/Hyperactivity Disorder (ADHD) may display disruptive behaviors and show poor academic performance, it has been suggested that incorporating choice-making strategies into academic instruction could serve to increase academic engagement and task accuracy. The purpose of this study was to examine the effectiveness of iPad-based choice-making opportunities during math independent practice on each participant's task engagement, time required to complete task, task accuracy, and task completion, as well as the teacher and participants perceptions of social validity of the intervention. …

Teacher Graphing Practices For Linear Functions In A Covariation-Based College Algebra Classroom, Konda Jo Luckau

Theses and Dissertations

Graphing is a fundamental topic in algebra that is notoriously difficult for students. Much of the past research has focused on conceptions and misconceptions. This study extends past research by looking at the mathematical practices of a practitioner, specifically one instructor of a function-based covariation-focused algebra class in the linear functions unit. Considering practices in addition to conception adds dramatically to our understanding of mathematical activity because it leads to explicit descriptions of normative purposes that are connected to particular situations or problems and also specifies how tools and symbols are coordinated to achieve these purposes. The results of this …

The Effects Of Stem Education On Economic Growth, Mallory Croak

Honors Theses

This thesis aims to build on existing studies of human capital and returns to education with a focus on innovation-fueling, STEM-based education, to answer: How does STEM education affect macroeconomic growth across different countries? A review of literature reveals that many studies account for human capital in growth equations, measured as average years of education. However, educational attainment as a measure of human capital leaves out the additional impact of research, technological know-how and innovation on growth. This thesis seeks to bridge some of the overlap between education and innovation as it affects productivity by focusing on education in STEM—fields …
