An Investigation Of The Instructional Norms Of Mathematical Communication When Students Present Geometry Proofs At The Board, Bukola T. Ake

Electronic Theses and Dissertations

Expert mathematical communication is a synthesis of speaking, writing, diagramming, and gesturing. What opportunities are there for secondary mathematics students to learn the discipline-specific ways in which these modalities can be combined to communicate proofs? In an initial effort to investigate this question, Dimmel and Herbst (2020) conducted a multimedia survey experiment to test a hypothesis about how secondary mathematics teachers expect students to communicate when presenting proofs at the board in secondary geometry classrooms. Their hypothesis, based on an analysis of episodes of instruction from a small sample of secondary geometry classrooms, was that teachers expected student presentations of …

Technology-Based Culturally Relevant Chemistry Education (Crce), Mercy Adoma Fosu

Electronic Theses and Dissertations

The relevance of chemistry concepts and principles remains a challenge for most students enrolled in college chemistry courses. Part of this problem is the disconnect with what students experience in their every-day lives, and how the material, specifically chemistry content is presented via textbooks, lectures, and laboratory teaching. Moreover, the teaching of general chemistry has traditionally focused on traditional, instructor-centric expository delivery of course materials, that treats students as empty vessels devoid of prior knowledge. Students prior knowledge and experiences are crucial in shaping their understanding of scientific concepts and principles. Even students with relatively low expectations for success in …

This research addresses these uncertainties using a variety of approaches to understand the effects of modern climate-driven changes on Lake Superior diatom communities. First, I developed models for environmental variables related to diatom abundance using 10 years of summer monitoring data. Second, I investigated changes in fossilized diatom relative abundances before, during, and after the Medieval …

Using Contrasting Cases To Build Metacognitive Knowledge About The Impact Of Salient Distracting Features In Physics Problems, Thanh K. Le

Electronic Theses and Dissertations

Student reasoning on physics problems is often context dependent. A possible explanation is that salient distracting features (SDFs) in physics problems may cue students’ “spontaneous” reasoning. This cued reasoning is often accepted without question, even though it may be unproductive and may even preclude the use of relevant knowledge. One possible approach to address such reasoning difficulties is to strengthen students’ metacognitive skills, particularly their metacognitive knowledge. While metacognitive knowledge plays an important role in facilitating effective regulation, little is known about how to build student metacognitive knowledge. This dissertation explores the use of contrasting cases (e.g., a …

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 …
