Intermediate Algebra Students’ Perspectives Towards Learning Mathematics, And Technology, Caree J. S. Pinder

USF Tampa Graduate Theses and Dissertations

Research states that many remedial mathematics learners possess low mathematics academic self-concept, negative attitudes, and high anxiety levels. These aspects can manifest in a lack of confidence, apprehension, reduced engagement, or academic failure (2007; Klinger, 2008; Larkin & Jorgensen, 2016; Parnis & Petocz, 2016;). However, if these learners successfully pass remedial mathematics courses like Intermediate Algebra, they are more likely to persist in mathematics and the university (Benken et al., 2015). Due to students' success in remedial mathematics, persistence in mathematics raises many questions. In many cases, these students have had unpleasant experiences, attitudes, or beliefs about mathematics but were …

Young Adolescents’ Opportunity To Develop Concept Images Of Polygons In Middle School Mathematics Textbooks, Megan N. Cannon

USF Tampa Graduate Theses and Dissertations

Young adolescents build notions of figures through experiences. When young adolescentsbegin middle school mathematics, they already have prior assumptions and conceptualizations about shapes (Herbst, Fujita, Halverscheid, & Weiss, 2017). Over years of experiences, interactions, and exposures with a particular concept, these students develop concept images consisting of all the visual information, pictures, mental images, or properties associated with the particular mathematical concept (Vinner, 1983). Seminal works in the field of mathematics education research found that without an opportunity to engage with varied representations, young adolescent students may not develop robust concept images (Aspinwall, Shaw & Presmeg, 1997; Hasegawa, 1997; Mesa, …

Advancing Functional Scientific Literacy To Socioscientific Literacy As A Cross Disciplinary Educational Goal: A Philosophical Analysis, Kory Bennett

USF Tampa Graduate Theses and Dissertations

Educational experiences built upon the Socioscientific Issues (SSI) framework provide opportunities for teachers and students to reflectively and reflexively address ill-defined complex scientific issues that affect human beings around the planet. Through the practice of Socioscientific Reasoning (SSR), while grappling with SSI, students have the potential to develop a SSI functional perspective of scientific literacy (SL); functional scientific literacy (FSL). Due to the multidimensional complexity of many human issues in and out of the science classroom, students are required to develop various skills, dispositions, and problem-solving strategies that expand from and connect with a SSI functional perspective of SL. The …

Teacher Certification Pathway And Mathematical Quality Of Instruction, Gail Stewart

USF Tampa Graduate Theses and Dissertations

The formal documentation of alternative routes to teacher certification programs in the United States began in 1983 (Ludlow, 2011). According to the former US Secretary of Education’s Annual Report on teacher quality the high demand for teachers in high needs areas, such as mathematics, has caused growth in alternative certification routes for teachers (Paige, 2002). The many factors that influence teaching quality make it difficult to determine what impact, if any, a teacher’s preparation program has on the quality of their instruction. Current research on teacher quality shows varied results, making it hard to reach a conclusion about the effectiveness …

Developing And Facilitating Socioscientific Issues Based Science Lessons: Elementary Preservice Teachers’ Experiences, Melanie Kinskey

USF Tampa Graduate Theses and Dissertations

Instruction focused around socioscientific issues (SSI) has been found to improve skills for scientific literacy among K – 12 students. Unfortunately, teachers and preservice teachers are reluctant to implement SSI during science instruction due to a lack of self-efficacy or fear of the nature of controversial issues. In response to this obstacle, many researchers have begun work with helping preservice teachers become prepared to facilitate SSI. While there are findings from existing research that contribute to the overall state of preparing preservice teachers to facilitate SSI, perhaps the most influential is the assertion that preservice teachers need formal SSI training …
