The Relationship Between Extracurricular Stem Activities And Performance On The Florida Science Assessment, Karin Fisher Jan 2016

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 …

Have Gender Gaps In Math Closed? Achievement, Teacher Perceptions, And Learning Behaviors Across Two Ecls-K Cohorts, Joseph R. Cimpian, Sarah T. Lubienski, Jennifer D. Timmer, Martha B. Makowski, Emily K. Miller Jan 2016

Have Gender Gaps In Math Closed? Achievement, Teacher Perceptions, And Learning Behaviors Across Two Ecls-K Cohorts, Joseph R. Cimpian, Sarah T. Lubienski, Jennifer D. Timmer, Martha B. Makowski, Emily K. Miller

Mathematics Faculty Publications

Studies using data from the Early Childhood Longitudinal Study–Kindergarten Class of 1998–1999 (ECLS-K:1999) revealed gender gaps in mathematics achievement and teacher perceptions. However, recent evidence suggests that gender gaps have closed on state tests, raising the question of whether such gaps are absent in the ECLS-K:2011 cohort. Extending earlier analyses, this study compares the two ECLS-K cohorts, exploring gaps throughout the achievement distribution and examining whether learning behaviors might differentially explain gaps more at the bottom than the top of the distribution. Overall, this study reveals remarkable consistency across both ECLS-K cohorts, with the gender gap developing early among high …

The Role Of Virtual Avatars In Supporting Middle School Students From Culturally And Linguistically Diverse Backgrounds On Science In After School Programs, Benjamin Gallegos Jan 2016

The Role Of Virtual Avatars In Supporting Middle School Students From Culturally And Linguistically Diverse Backgrounds On Science In After School Programs, Benjamin Gallegos

Electronic Theses and Dissertations

Students who receive additional educational supports in afterschool programs were the focus of the investigation. This study was conducted to measure what effects a TeachLivE avatar, a mixed-reality virtual environment, used in combination with a video game, had on the activation of prior knowledge in science for students in rural middle school. The delivery of the biology science lessons on cell structures and processes were delivered using the video game, Cell Command. The TeachLivE adult avatar was customized as a biologist who spoke to students in the treatment group about science concepts prior to playing the science video game. Unexpected …

Project Ican: A Stem Learning And Persistence Model For Postsecondary Students With Disabilities, Aaron Koch Jan 2016

Project Ican: A Stem Learning And Persistence Model For Postsecondary Students With Disabilities, Aaron Koch

Electronic Theses and Dissertations

Education and work in Science, Technology, Engineering, & Math (STEM) are of utmost importance in a post-modern society. Yet American performance in the STEM disciplines has waned over recent years. In order to recapture a global advantage in STEM, efforts are being made by educators and policy makers to compile and implement instructional supports. Of particular interest to this study are post-secondary students with disabilities (SWDs) who persist and learn in STEM degree paths. This population is an "untapped resource" with limitless potential for contribution to the collective fields of STEM (Leddy, 2010, p. 3; Alston, Hampton, Bell, & Strauss, …

A Multiple Case Study Examining How Third-Grade Students Who Struggle In Mathematics Make Sense Of Fraction Concepts, Rebecca Gault Jan 2016

A Multiple Case Study Examining How Third-Grade Students Who Struggle In Mathematics Make Sense Of Fraction Concepts, Rebecca Gault

Electronic Theses and Dissertations

A qualitative multiple case study was conducted to reveal the sense-making processes third-grade students who struggle in mathematics used to build an understanding of fraction concepts. Purposive sampling identified three participants who were struggling in a local school's third grade mathematics classes. This research describes how these participants made sense of fraction concepts through their strengths and struggles while engaged in 15 small-group intervention sessions. Vygotsky's (1934/1986/2012) theory that children's optimal learning is supported by teacher-student interactions was used as an interpretive framework. Tasks were developed over the course of the intervention sessions with consideration of a model developed by …

Exploring Meteorology Education In Community College: Lecture-Based Instruction And Dialogue-Based Group Learning, Jason Paul Finley Jan 2016

Exploring Meteorology Education In Community College: Lecture-Based Instruction And Dialogue-Based Group Learning, Jason Paul Finley

Educational Studies Dissertations

This study examined the impact of dialogue-based group instruction on student learning and engagement in community college meteorology education. A quasi-experimental design was used to compare lecture-based instruction with dialogue-based group instruction during two class sessions at one community college in southern California. Pre- and post-tests were used to measure learning and interest, while surveys were conducted two days after the learning events to assess engagement, perceived learning, and application of content. The results indicated that the dialogue-based group instruction was more successful in helping students learn than the lecture-based instruction. Each question that assessed learning had a higher score …

An Exploration Of Success Factors From The Perspectives Of Developmental Mathematics Students, Stacy Atkinson Jan 2016

An Exploration Of Success Factors From The Perspectives Of Developmental Mathematics Students, Stacy Atkinson

Educational Studies Dissertations

Students who enter college underprepared for college-level coursework face tremendous barriers, including referral to one or more levels of developmental education. However, the requirement to complete developmental mathematics often becomes a primary barrier for students ever being able to complete a degree. Students who enter underprepared for college-level coursework and also identify as first-generation face even larger barriers to realizing success. Given this reality, community colleges – where most developmental education programs are housed – are seeking ways to better support students needing remediation to increase their chances of success and completion. Using the recently implemented co-requisite model of instruction …

Preservice And Practicing Teacher Science Inquiry Projects: An Analysis Of Their Understanding Of The Inquiry Process, Benjamin D. Olsen Jan 2016

Preservice And Practicing Teacher Science Inquiry Projects: An Analysis Of Their Understanding Of The Inquiry Process, Benjamin D. Olsen

Dissertations and Theses @ UNI

Student conducted inquiry is an essential component of the Next Generation Science Standards and considered to be a core goal of teaching science methods. Teachers need to understand what student inquiry entails, to be able to successfully conduct their own inquiry investigations, and to understand this process well so as to guide original student inquiry investigations. Some suggest that, as a result of No Child Left Behind legislation, an entire generation of students have missed out on inquiry-based elementary science instruction. Research indicates that many preservice teachers find it difficult to bridge knowledge of subject matter with pedagogy – making …
