National efforts to interest students in STEM careers are intensifying around the globe, due to a shortage of professionals to fill the growing demands in these fields. Although some US studies find high interest in STEM in K-12 students, longitudinal studies show a decline in interest following middle school. Many students, particularly females…

Previous research in the field of heritage language (HL) acquisition has focused on the connection between frequency of language use and HL speakers' connection to and maintenance of their HL. This dissertation introduces the concept of positioning through discourse into the study of HLs to show evidence that while frequency of HL use contributes…

This research explores the implementation and utilization of self-regulated learning (SRL) scaffolds (i.e. videos, journals, surveys) in online K-12 courses. This project is grounded in research on online education as well as theory and research around self-regulated learning in both online and offline contexts. This research is conducted through…

African-American youth experience disproportionate rates of childhood obesity compared to their White counterparts. Culturally tailored electronic media solutions hold the potential to overcome health literacy and health communication barriers. This study aimed to identify the impact of exposure to a new website portal…

In this article, we focus on the use of the visual for reflection in "alternative" pre-service teacher education and, in particular, we address the question: "How and what can we learn about teacher education using the visual?" By way of illustration, we focus on the use of pre-service teachers' photographs in a public…

Previous literature shows that language input is related to the language that children produce. Less is known about how the input provided to children relates to the way that they process language. In this study, this question was explored by looking at the relationships between children's word learning ability and the kinds of names provided by…

This research provides an analysis of the relationship between a student's beliefs and mathematical behaviors over a seventeen-year period. Romina, the student of focus in this case study, was among the original participants in a longitudinal study which explored how students build mathematical ideas when working collaboratively on problem-solving…

Questioning is an essential and generative studying practice for prospective teachers (PTs) as they develop their mathematical content knowledge needed for teaching. This study examines PTs' questioning interactions by describing the types of questions they ask during small group discussions in a required mathematics content course and how their…

Research has long recognized the value of video technology in supporting preservice teachers' learning, and recent technological and conceptual advances further demonstrate its potential as an everyday tool for teacher education. This dissertation examines video's role in efforts to develop a "practice-based" curriculum for teacher education.…

While the notion of numeracy as the capacity to make use of mathematics within contexts associated with personal and public life, as distinct from basis mathematical competence, is broadly accepted, forms of professional teacher learning that lead to the effective teaching of numeracy are still the subject of ongoing research. This paper reports…

As one research priority for mathematics education is "to research how mathematical meanings are structured by tools available," the present study examined mathematical representations more closely by investigating instructional modes of representation (Noss, Healy & Hoyles, 1997). The study compared two modes of instruction of place value with…

The purpose of this study was to examine the similarity of outcomes from three different treatment integrity (TI) methods, and to identify the method which best corresponded to the assessment of a child's behavior. Six raters were recruited through individual contact via snowball sampling. A modified intervention component list and 19 video clips…

Surveillance video recording is becoming ubiquitous in daily life for public areas such as supermarkets, banks, and airports. The rate at which surveillance video is being generated has accelerated demand for machine understanding to enable better content-based search capabilities. Analyzing human activity is one of the key tasks to understand and…

"Number Talks" is: (1) A five- to fifteen-minute classroom conversation around purposefully crafted computation problems that are solved mentally; and (2) The best part of a teacher's day. Whether you want to implement number talks but are unsure of how to begin or have experience but want more guidance in crafting purposeful problems, this…

Early in 2010, the E-Expectations research group surveyed more than 1,000 college-bound high school students, polling them on their online behaviors and expectations, as well as other key enrollment-related topics. Highlights of the study include: (1) 1 in 4 students reported removing a school from their prospective list because of a bad…
