Elementary Preservice Math Teachers’ Evolving Dispositions Throughout A Math Methods Course: A Mixed Methods Study, Christine E. Hood

Electronic Theses and Dissertations

This study aimed to understand graduate-level Elementary Preservice Teachers’ (EPST) mathematical dispositions before, during, and after a graduate elementary math methods course taught through a rehumanizing (Gutiérrez, 2018), ambitious and equitable math (Horn & Garner, 2022) teaching framework. In this study, EPSTs’ dispositions included four constructs: math anxiety, math teaching anxiety, math self-efficacy, and math teacher self-efficacy. To fully understand the nuance and complexity of teacher education and EPSTs’ mathematical dispositions, I looked at both the EPSTs' and the instructors' perspectives. I investigated EPSTs’ dispositions through a modified multi-methods, sequential, and phenomenological lens. For the instructors’ perspectives, I conducted a …

A Phenomenological Study Of Science Teachers’ Lived Experience: Pedagogical Judgment During The Covid-19 Pandemic, Amy Vo

Electronic Theses and Dissertations

At the beginning of the COVID-19 pandemic, in March of 2020, education in the United States changed dramatically. Science teachers began to look at the implementation of ambitious and equitable science teaching practices differently. Employing the hermeneutic phenomenological framework, the purpose of this study was to investigate the lived experience of science teachers, specifically looking at their pedagogical judgment related to ambitious and equitable science teaching. Semi-structured interviews, artifacts and surveys were used to develop a rich description of the phenomenon. Data analysis of the science teachers’ narratives, Qualtrics surveys, and lesson plans illuminated six essential themes common to all …

High Quality, Equity, And Assessment: An Analysis Of Variables Impacting English Learner Standardized Science Test Performance And Implications For Construct Validity, Maria Del Carmen Salazar, Joanna K. Bruno, Melissa P. Schneider

Curriculum and Instruction: Faculty Scholarship

In the United States, assessment is seen as a lever that can facilitate high-quality education. This study on English learners, students whose native language is not English, was based on data from eighth-grade English learners’ performance on science general and content-specific (physical, life, and earth science) standardized exams and an English language proficiency exam. The researchers utilized regression analysis to examine factors (i.e., socioeconomic status, home language, English language proficiency, and receptive and productive elements of language) that are predictive of English learner performance in general and content-specific science standardized assessments to identify implications for construct validity of high-stakes science …

Understanding Why Women Stay: Examining Persistence Factors Of Women Majoring In Science And Technology Programs In Public Ethiopian Universities Using A Mixed Methods Design, Meseret Hailu

Amongst African nations, Ethiopia is a unique case in many respects. The country has the second largest population on the continent, is currently experiencing an economic boom, and is a relatively stable nation in the geopolitically volatile "Horn of Africa" region. In the past two decades, the higher education sector in Ethiopia has experienced rapid growth, as evidenced by an increase in both student enrollment and the number of universities. Amongst the various types of higher education institutions, public universities are especially important because they receive the greatest financial support from the Ministry of Education. Moreover, science and technology programs …

Using Student And Teacher Thinking To Improve Teaching And Learning, Ken Jensen

Teaching and Learning Sciences: Doctoral Research Projects

This research project examined how a teacher and an instructional coach can use formative assessment data on student thinking to improve the teaching and learning in a mathematics classroom. Two research questions guided the project and from them three instructional strategies emerged. The first strategy was the use of formative assessment data collected on student thinking from a previous lesson to plan for the learning in future lessons. The second strategy was the use of formative assessment data collected on student thinking during a lesson to make decisions about how to proceed with the lesson. The third strategy was the …

Mathematics Teachers' Beliefs And Mathematical Knowledge For Teaching: How Teachers' Mkt Shifts In Planning And Impacts Their Beliefs And Instructional Practice, Paul Conley

Electronic Theses and Dissertations

In an effort to understand how a teacher developed Mathematical Knowledge for Teaching and how that knowledge can shift teacher's beliefs and instructional practice, I worked with a teacher to deeply plan and implement six mathematical lessons.

The research suggests that planning can be a vehicle to develop a teacher's Mathematical Knowledge for Teaching. In addition, as a teacher's Mathematical Knowledge for Teaching started to develop through lesson planning, the teacher's beliefs about her own knowledge of mathematics started to increase which started to shift the teacher's instructional practice.

This combination of a stronger Mathematical Knowledge for Teaching, self confidence …

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 …

A Narrative Study Of Novice Elementary Teachers' Perceptions Of Science Instruction, Roberta Harrell

Electronic Theses and Dissertations

It is hoped that, once implemented, the Next Generation Science Standards (NGSS) will engage students more deeply in science learning and build science knowledge sequentially beginning in Kindergarten (NRC, 2013). Early instruction is encouraged but must be delivered by qualified elementary teachers who have both the science content knowledge and the necessary instructional skills to teach science effectively to young children (Ejiwale, 2012, Spencer, Vogel, 2009, Walker, 2011). The purpose of this research study is to gain insight into novice elementary teachers’ perceptions of science instruction.

This research suggests that infusion of constructivist teaching in the elementary classroom is beneficial …

Evolving Minds: Helping Students With Cognitive Dissonance, Terry L. Bramschreiber

Electronic Theses and Dissertations

Even 150 years after Charles Darwin published On the Origin of Species, public school teachers still find themselves dealing with student resistance to learning about biological evolution. Some teachers deal with this pressure by undermining, deemphasizing, or even omitting the topic in their science curriculum. Others face the challenge and deliver solid scientific instruction of evolutionary theory despite the conflicts that may arise. The latter were the topic of this study.

I interviewed five teachers that had experience dealing with resistance to learning evolution in their school community. Through these in-depth interviews, I examined strategies these teachers use when …

Attending High School Algebra I: In Search Of Well-Managed, Engaging, Culturally Relevant, And Caring Classrooms, Cassandra Dunn Gannett

Electronic Theses and Dissertations

The inequities in learning between the rich and the poor have become pervasive in United States. This is evidenced by the high school graduation rates, college attendance percentages, and employment statistics. Upon another wave of reform, the Common Core State Standards in mathematics are currently being adopted in hopes of increasing learning for all students, with a focus on college and career readiness. This study is intent on finding ways to remedy the inequities in mathematics between the high income and low income schools by focusing on one of the great glass ceilings to high school graduation and beyond, high …

Executive Function Development And Early Mathematics: Examination Of Dual Language Learners, Hattie A. Harvey

Electronic Theses and Dissertations

This study examined the convergent validity between a third-party rating scale of executive function (EF) and a task-performance measurement of EF; examined the effects of age, gender, and dual language experience on preschool children‘s EF skills (inhibition, working memory (WM), and shifting) and on early mathematical skills; and investigated the contributions of inhibition, WM, and shifting to early mathematical skills. Ninety-two children attending Head Start were assessed. Correlation analyses revealed a number of relationships between the EF rating scale and the EF taskperformance measure. A multivariate analysis of variance revealed a main effect of age on all EF measures and …

An Analysis Of Mathematics Interventions: Increased Time-On-Task Compared With Computer-Assisted Mathematics Instruction, James M. Calhoun Jr.

Electronic Theses and Dissertations

Student achievement is not progressing on mathematics as measured by state, national, and international assessments. Much of the research points to mathematics curriculum and instruction as the root cause of student failure to achieve at levels comparable to other nations. Since mathematics is regarded as a gate keeper to many educational opportunities as well as, eventually, potential job prospects, critics are asking schools to fix the problem.

This research project is a comparison of two different interventions used to improve student performance as tested on the Colorado State Assessment Program (CSAP). The first intervention, increased time-on-task, was used at Freedom …

Toward Using Games To Teach Fundamental Computer Science Concepts, Jeffrey Michael Edgington

Electronic Theses and Dissertations

Video and computer games have become an important area of study in the field of education. Games have been designed to teach mathematics, physics, raise social awareness, teach history and geography, and train soldiers in the military. Recent work has created computer games for teaching computer programming and understanding basic algorithms.

We present an investigation where computer games are used to teach two fundamental computer science concepts: boolean expressions and recursion. The games are intended to teach the concepts and not how to implement them in a programming language.

For this investigation, two computer games were created. One is designed …

Investigating Instructors' Conceptions Of Evolution Through The Development Of The Classroom Test Of Evolutionary Reasoning, Patricia Eileen Palko

Electronic Theses and Dissertations

In order to assess the evolutionary understanding of high school biology teachers, an instrument entitled the Classroom Test of Evolutionary Reasoning (CTER) was developed. Content, response process, relations to another variable (the Conceptual Inventory of Natural Selection, or CINS), and internal structure evidence were compiled. The second version of the CTER was found to have adequate reliability and validity estimates to allow it to continue to be used as a measurement tool for an understanding of evolution. When assessing a sample of teachers (n = 724), the mean score was 6.35 out of a possible 13 points. The sample was …

Effects Of Participation In Inquiry Science Workshops And Follow-Up Activities On Middle School Science Teachers' Content Knowledge, Teacher-Held Misconceptions, And Classroom Practices, Linda F. Cepeda

Electronic Theses and Dissertations

An important aspect of developing science literacy for all students is developing science-literate teachers. With the implementation of the No Child Left Behind Act, many middle school teachers found themselves in a position where they were no longer qualified to teach middle school science. This study was designed to help science teachers increase their science content knowledge, identify and resolve misconceptions/errors they may have, and assist them in their teaching by providing strategies for inquiry-based teaching, science laboratory exercises, and science equipment.

Teachers enrolled in biology courses offered by the Rocky Mountain Middle School Math and Science Partnership participated in …
