A Standards-Based Grading Model To Predict Students' Success In A First-Year Engineering Course, Farshid Marbouti

Open Access Dissertations

Using predictive modeling methods, it is possible to identify at-risk students early in the semester and inform both the instructors and the students. While some universities have started to use standards-based grading, which has educational advantages over common score-based grading, at–risk prediction models have not been adapted to reap the benefits of standards-based grading. In this study, seven prediction models were compared to identify at-risk students in a course that used standards-based grading. When identifying at-risk students, it is important to minimize false negative (i.e., type II) errors while not increasing false positive (i.e., type I) errors significantly. To increase …

The Processing Of Formulaic Language On Elicited Imitation Tasks By Second Language Speakers, Yan Xun

Open Access Dissertations

The present study investigated the processing of formulaic language, in an effort to examine how the use of formulaic language may or may not contribute to second language (L2) fluency in speaking performance. To examine the effect of formulaic language on L2 fluency, this study utilized elicited imitation (EI) tasks designed to measure general English language proficiency in order to compare repetition of individual sentences containing formulaic sequences (FS) to repetition of sentences that do not. In addition to the presence of FS, the length of stimuli sentences was manipulated and compared to a second independent variable. Responses to EI …

Beliefs About Toddler And Care: A New Measure For Infant Toddler Teachers, Treshawn L Anderson

Open Access Dissertations

Development And Validation Of Pre-Service Teachers' Personal Epistemologies Of Teaching Scale (Pt-Pets), Ji Hyun Yu

Open Access Dissertations

The Internet has changed not only how we conceptualize knowledge, but also how we learn in classroom. Knowledge is not any longer transmitted from experts to non-experts, but is constructed through communication, collaboration, and integration among a network of people. In this context, teachers are expected to facilitate student-centered learning by helping students to construct knowledge through higher-order thinking rather than reproduce a series of facts. Although a growing body of research suggests that teachers' beliefs about the nature of knowledge and the process of knowing, that is personal epistemology, are related to their teaching and their students' learning, little …

Open Access Dissertations

The EFA conference in Dakar 2000 ushered in new momentum for ensuring universal access to education and advocacy for improved educational quality in all aspects (UNESCO, 2000). While significant progress has been made in expanding access in sub-Saharan Africa, particularly for girls, efforts to ensure improved educational quality in terms of learning, have not matched the drive for universal educational access. Rather, educational quality in most countries in sub-Saharan Africa has been seriously compromised by rapid expansion given the limited resources.

In many attempts to ensure the delivery of quality education in developing countries, the thrust of delivery strategies has …
