Discussion In Middle And High School Earth Science Classrooms And Its Impact On Students' Abilities To Construct Evidence-Based Arguments In Their Written Work, Rachel Martin

Electronic Theses and Dissertations

Middle and high school teachers who participate in the Maine Physical Sciences Partnership (MainePSP) noted persistent problems in their classrooms, including low levels of student engagement and gaps in how students use evidence. To address these problems, this study was designed in collaboration with MainePSP teachers in a design-based implementation research process as teachers aimed to better connect classroom discussion and written argumentation. Though scientific writing makes use of argumentation to support ideas, it is often the sharing of ideas that makes an argument stronger.

Two teachers collected data from their seventh and ninth grade Earth Science classrooms at schools …

Calculus Students' Reasoning About Slope And Derivative As Rates Of Change, Jennifer G. Tyne

Electronic Theses and Dissertations

Students’ low success rates in college calculus courses are a factor that leads to high attrition rates from science, technology, engineering and mathematics (STEM) degree programs. To help reach our nation’s goal of one million additional STEM majors in the next decade, we must address the conceptual difficulties of our students. Studies have shown that students have difficulty with the concepts of slope and derivative, especially in cases when students are asked to utilize these concepts in real-life contexts.

For this study, written surveys were collected from 69 differential (first semester) calculus students. Follow-up clinical interviews were performed on 13 …

Inconsistent Conceptions Of Acceleration Contributing To Formative Assessment Limitations, Gregory D. Kranich

Electronic Theses and Dissertations

Science, technology, engineering, and mathematics (STEM) education has become a national priority in light of measures indicating marginal student interest and success in the United States. Just as evidence is integral to policy decisions, so too do teachers depend on evidence to inform instructional choices. Classroom assessment remains a touchstone means of gathering such evidence as indicators of students’ progress, and increasingly, teachers are designing, implementing, and interpreting assessments in collaboration with one another.

In rural Maine, the work of the Maine Physical Sciences Partnership (MainePSP) has enabled science educators to come together as a supportive professional community. We focused …

Facilitating Conceptual Learning In Quantitative Chemistry, Sarah R. Johnson

Electronic Theses and Dissertations

Traditional chemistry laboratory courses have a manual consisting of “step-by-step” experiments; instructions are given to complete experiments, requiring minimal information/concepts processing to be successful. This experience leaves students unprepared for the real-world, where critical thinking skills are needed to conduct research. This study focused on building analytical techniques, conceptual knowledge, and critical thinking skills used to solve research problems. A new quantitative chemistry laboratory manual was developed to transition students from traditional to inquiry-based experiments, requiring analytical method development. Data showed students having less difficulty using the new manual (0.8281 average difficulty) on method development exam questions and experiments, compared …

Structural-Symbolic Translation Fluency: Reliability, Validity, And Usability, Matt C. Hoskins

Electronic Theses and Dissertations

Standardized formative mathematics assessments typically fail to capture the depth of current standards and curricula. Consequently, these assessments demonstrate limited utility for informing the instructional implementation choices of teachers. This problem is particularly salient as it relates to the mathematical problem solving process. The purpose of this study was to develop and evaluate the psychometric characteristics of Structural-Symbolic Translation Fluency, a curriculum-based measure (CBM) of mathematical problem solving. The development of the assessment was based on previous research describing the cognitive process of translation (Mayer, 2002) as well as mathematical concept development at the quantitative, structural, and symbolic levels (Dehaene, …

Setting The Agenda For Stem Literacy In Higher Education: A Content Analysis Of The Chronicle Of Higher Education, Maya Abdallah

Electronic Theses and Dissertations

Enhancing achievement in Science, Technology, Engineering, and Mathematics (STEM) is a long-standing national concern. The current national agenda, to instill an "all hands on deck" approach to creating a STEM literate citizenry, calls for broadening the scope of inclusion in STEM efforts. A critical population, higher education administrators, faculty, and staff are a valuable resource to advancing this agenda. Under the proposed Agenda Setting Communication Theory (ASCT) model developed for this study, their level of exposure to needed information is an important indicator of their potential participation in this agenda. As the leading news medium for the higher education community, …

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 …

The Influence Of Instruction In Base 8 On Prospective Teachers' Mathematical Knowledge For Teaching, Katie Harshman

Electronic Theses and Dissertations

The focus of this research project was to extend existing research literature by providing insight to how prospective teachers with differing levels of mathematical knowledge developed their conceptual understanding of whole number concepts and operations. Prospective teachers of interest were enrolled in an Elementary School Mathematics Course for Teachers (in the College of Education) with a whole number concepts and operations unit set entirely in base 8. In this mixed-mode study, participants were given the MKT, a measure designed to measure teacher mathematical knowledge for teaching, before and after taking the base 8 unit. The researcher focused on two specific …

Adair Instrumental Genesis Inventory: Measuring Instrumental Genesis For Interactive Whiteboard Technology—An Exploratory Sequential Mixed Methods Design, Mindy H. Adair

Electronic Theses and Dissertations

The adoption of interactive whiteboard technology in the mathematics classroom has been reasonably explored in terms of effective use (Glover & Miller, 2009), student engagement (Morgan, 2008) and achievement (Lutz, 2010), pedagogy (G. Beauchamp & Kennewell, 2013), and learning environments (Yang, Wang, & Kao, 2012). However, there has been little research performed regarding how teachers actually become effective at orchestrating and managing the technology in the classroom in terms of their level of instrumental genesis attainment. In this study, I examined how a teacher develops instrumental genesis, the two-fold process involving instrumentation and instrumentalisation, with interactive whiteboard technology through an …

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 …
