The Relationship Between Extracurricular Stem Activities And Performance On The Florida Science Assessment, Karin Fisher

Electronic Theses and Dissertations

Students with disabilities perform below their non-disabled peers in science (National Center for Educational Statistics [NCES], 2011; National Educational Longitudinal Study [NELS], 1998; National Science Foundation [NSF], 2013). The achievement gap is a problem because the nation's competitiveness depends on individuals with science, technology, engineering, and mathematics (STEM) knowledge, skills, and abilities to drive innovation that will lead to new products and economic growth (Business-Higher Education Forum [BHEF]/Act Policy Brief, 2014; National Academies of Sciences, Engineering, and Medicine, 2016; National Science Board, 2015). If Florida is to continue to grow and prosper, all students, including students with disabilities must be …

Investigating Math Students' Ability To Conceptualize Fractions As Two Numerals Having A Single Value, William Carroll Fanning

Open Access Theses & Dissertations

It is no secret that math students of all ages have misconceptions about fractions. Multiple studies have shown that math students invariably see fractions as two separate and unrelated numbers, the numerator and the denominator, rather than a single number with specific value. This study is designed to investigate studentsâ?? interpretations of a fraction in terms of having a single value in relation to its two numbers, the numerator and the denominator.

For the purpose of this study, the investigator developed and pilot-tested seven items that have the potential to uncover whether students attend to the value of a fraction …

Over the years women have made significant advances in the workforce and in science, technology, engineering, and mathematics (STEM) fields, but there are still disparities that exist and are yet to be overcome. Women are still underrepresented in many STEM fields and progress still needs to be made. There is significant research backing this up and trying to explain why these issues still exist. In June 2015, The University of Akron put on a See UA! Women in Engineering Camp that allowed high school females interested in engineering the opportunity to learn more about engineering, the different possible fields within …

Calculators In High School Classrooms, Adam P. Rohrabaugh, Clay M. Cooper

Williams Honors College, Honors Research Projects

In today’s mathematics classrooms, calculators are becoming incredibly well known and used almost daily. However, there has been a common question about the use of these calculators: Is too much exposure to calculators causing students to become dependent on them and consequently start to forget basic addition, subtraction, multiplication, and division, leading into confusion on other mathematics topics because the most basic foundation of mathematics is not there? The purpose of this paper is to discuss both sides of this question by looking at different studies as well as provide our own experiences with this subject while working in different …

A Review Of Secondary Mathematics Textbooks On Families Of Functions, Emily Nyszczy

Williams Honors College, Honors Research Projects

In 2008, twelve commonly used textbooks were studied for their use of technology and content across 5 families of functions: polynomial, rational, exponential, logarithmic, and trigonometric. Since 2008, the Common Core State Standards have been released and many textbook companies have used this as an opportunity to change their textbook content. This study reevaluates new high school algebra and precalculus textbooks across many of the same criterion studied in 2008. Some topics such as increasing and decreasing functions significantly increased their presence in the mathematics textbooks while topics such as sketching graphs has decreased. The reason for this shift in …

Strengthening Elementary Students' Understanding Of Factors, Jordan R. Frotz

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Research on pre-service elementary school teachers’ understanding of the multiplicative structure of the natural numbers demonstrates an under-utilization of unique prime factorization in the identification of a number’s factors. For example, Zazkis and Campbell (1996b) found that a majority of teacher candidates employed trial division to analyze factor-candidates of a number, even when both were presented in prime-factored-form. Recent studies (i.e. Roscoe & Feldman, 2015) have shown that teachers’ understanding of factor can be strengthened by engaging in a sequence of instructional tasks that explore the relationship between a number’s prime factorization and its factors. This study seeks to extend …

A Meta-Analysis Of Middle School Science Engagement, Leanna B. Aker

Education Dissertations

Researchers and educational practitioners have long been concerned with declines in science engagement reported by students as they transition into the middle school setting. Though the operationalization of engagement is still nascent, an emerging consensus on a three-faceted model of student engagement has recently emerged in the research literature (Fredricks, Blumenfeld, & Paris, 2004). Thus, a synthesis of existing primary research of early adolescents’ science engagement under this emerging conceptualization was warranted. The results of this meta-analysis indicate that instructional methods, class characteristics and competence predictors had the strongest relationship with self-reported science engagement in early adolescence. These predictors also …

Characterizing Mathematics Graduate Student Teaching Assistants’ Opportunities To Learn From Teaching, Yvonne Lai, Wendy Smith, Nathan Wakefield, Erica R. Miller, Julia St. Goar, Corbin M. Groothuis, Kelsey M. Wells

Department of Mathematics: Faculty Publications

Exemplary models to inform novice instruction and the development of graduate teaching assistants (TAs) exist. What is missing from the literature is the process of how graduate students in model professional development programs make sense of and enact the experiences offered. A first step to understanding TAs’ learning to teach is to characterize how and whether they link observations of student work to hypotheses about student thinking and then connect those hypotheses to future teaching actions. A reason to be interested in these connections is that their strength and coherence determine how well TAs can learn from experiences. We found …

Student Buy-In To Active Learning In A College Science Course, Andrew J. Cavanagh, Oriana R. Aragon, Xinnian Chen, Brian A. Couch, Mary F. Durham, Aiyana Bobrownicki, David I. Hanauer, Mark J. Graham

School of Biological Sciences: Faculty Publications

The benefits of introducing active learning in college science courses are well established, yet more needs to be understood about student buy-in to active learning and how that process of buy-in might relate to student outcomes. We test the exposure–persuasion– identification–commitment (EPIC) process model of buy-in, here applied to student (n = 245) engagement in an undergraduate science course featuring active learning. Student buy-in to active learning was positively associated with engagement in self-regulated learning and students’ course performance. The positive associations among buy-in, self-regulated learning, and course performance suggest buy-in as a potentially important factor leading to student …

Characterizing Student Perceptions Of And Buy-In Toward Common Formative Assessment Techniques, Kathleen R. Brazeal, Tanya L. Brown, Brian A. Couch

School of Biological Sciences: Faculty Publications

Formative assessments (FAs) can occur as preclass assignments, in-class activities, or postclass homework. FAs aim to promote student learning by accomplishing key objectives, including clarifying learning expectations, revealing student thinking to the instructor, providing feedback to the student that promotes learning, facilitating peer interactions, and activating student ownership of learning. While FAs have gained prominence within the education community, we have limited knowledge regarding student perceptions of these activities. We used a mixed-methods approach to determine whether students recognize and value the role of FAs in their learning and how students perceive course activities to align with five key FA …

We designed an interrupted case study in which students learn about and apply the scientific method to investigate and recapitulate the findings of a published research article. This research article addresses the question of how parents recognize their own young in a system where birds of the same …

Relationship Between Teacher Inquiry Science Instruction Self-Efficacy And Student Achievement, Grace Hanners

Walden Dissertations and Doctoral Studies

Standardized test data indicate that student achievement in science is a problem both nationally and locally. At the study site, only a small percentage of fifth-grade students score at the advanced level on the Maryland state science assessment (MSA). In addition, the performance of African American, economically disadvantaged, and special education students is well below that of the general student population. Some studies have shown that teacher self-efficacy affects student achievement. Therefore, the purpose of this study was to explore the relationship between fifth-grade teacher inquiry science instruction self-efficacy scores and the scores of their students on the MSA. Bandura's …

The multigenerational workforce presents a critical challenge for business managers, and each generation has different expectations. A human resource management study of organizations with more than 500 employees reported 58% of the managers experiencing conflict between younger and older workers. The purpose of this single case study was to explore the multigenerational strategies used by 3 managers from a Franklin County, Ohio manufacturing facility with a population size of 6 participants. The conceptual framework for this study was built upon generational theory and cohort group theory. The data were collected through face-to-face semistructured interviews, company documents, and a reflexive journal. …

Stem In General Education: Does Mathematics Competence Influence Course Selection, Mary C. Enderson, John Ritz

STEMPS Faculty Publications

Many students enroll in college programs to prepare for their future careers. All are required to complete general studies courses. At one university, technology and STEM courses fulfill a part of the natural science and technology general education requirements. This study uses a survey design to explore why 332 students chose to enroll in a STEM technology course. Results found most enroll because their advisor suggests the course, it meets a general education major requirement, and the course is offered at a convenient time. Fewer enroll in the course because they would like to find out more about STEM fields, …

Aspects Of Science Engagement, Student Background, And School Characteristics: Impact On Science Achievement Of U.S. Students, Larry J. Grabau

Theses and Dissertations--Educational, School, and Counseling Psychology

Science achievement of U.S. students has lagged significantly behind other nations; educational reformers have suggested science engagement may enhance this critical measure. The 2006 Program for International Student Assessment (PISA) was science-focused and measured science achievement along with nine aspects of science engagement: science self-efficacy, science self-concept, enjoyment of science, general interest in learning science, instrumental motivation for science, future-oriented science motivation, general value of science, personal value of science, and science-related activities.

I used multilevel modeling techniques to address both aspects of science engagement and science achievement as outcome variables in the context of student background and school characteristics. …
