The researcher found the research …

Instructional Teacher Job Resources And Student Achievement In Mathematics., Amy Stokes-Levine

Electronic Theses and Dissertations

Research shows that teachers who are supported with job resources are more engaged regardless of the level of demands (Klusmann et al., 2008). Additionally, teachers who are engaged with their work are less likely to report their intention to leave the teaching profession (Klassen et al., 2012), which is particularly important for mathematics teachers who are in high demand (Sutcher, Darling-Hammond, & Carver-Thomas, 2016). Supporting employees with job resources is a commonly accepted practice in many professional fields (e.g., Christian, Garza, & Slaughter, 2011), yet is not a common practice in education (e.g., Bidwell, 2013; Gewertz, 2014; Layton, 2015; Rentner …

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 …

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

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, …

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 …

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 …
