Excessive college course withdrawals are costly to the student and the institution in terms of time to degree completion, available classroom space, and other resources. Although generally well quantified, detailed analysis of the reasons given by students for course withdrawal is less common. To address this, a text mining analysis was performed…

In Mexico, as in many other countries, HIV/AIDS strategies are developed at the federal level and implemented at the state level. Local programs are expected to use data, in particular surveillance data, to drive their decisions on programmatic activities and prioritize populations with which the program will engage. Since the early 1980s Mexico…

This is a quasi-ethnographic (qualitative) interview examination of understanding teacher professional development for urban and suburban high school mathematics teachers. Since teacher professional development has been found to be critical in improving student learning such as mathematics achievement, and teacher professional development is…

Numerous challenges can be associated with pursuing a degree as a Certified Registered Nurse Anesthetist (CRNA). The risk to perspective students and their nurse anesthesia programs may be lessened if success factors for program completion and passing of the national certification examination (NCE) could be identified. The purpose of this ex post…

The purpose of this study was to examine the patterns of dialogue that were established and emerged in one experienced fifth-grade science teacher's classroom that used the argument-based inquiry (ABI) and the ways in which these patterns of dialogue and consensus-making were used toward the establishment of a grasp of science practice. Most…

Attrition rates are an indicator of a school's holding power, or ability to keep students enrolled in school and learning until they graduate. This study examines regional trends in Texas for the number and percent of students lost from public high school enrollment prior to graduation. A comparative analysis of 1985-86, 2005-06, 2006-07,…

If principals have the authority to dismiss teachers, will they dismiss the less effective ones, or will they instead make perverse decisions by letting the good teachers go? Evidence from low-stakes surveys suggests that principals are able to identify the most and least effective teachers in their schools, as measured by their impact on student…

Within universities there is often still an implicit assumption that the doctorate is preparation for an academic career. Yet for over a decade there has been evidence in a number of Organisation for Economic Cooperation and Development (OECD) countries that there are increasing numbers of students undertaking a doctorate and that larger…

Objective: To discuss implications for educational policy and practice relevant to closing the achievement gap based on the literature review and synthesis presented in 7 articles of the October 2011 special issue of the "Journal of School Health". Methods: Implications for closing the achievement gap are drawn from analyses of current literature.…

This article describes a model that can be used to analyze student enrollment data and can give insights for improving retention of part-time students and refining institutional budgeting and planning efforts. Adult higher-education programs are often challenged in that part-time students take courses less reliably than full-time students. For…

The Network for a Healthy California (Network) employs a Geographic Information System (GIS) to identify the target audience and plan program activities because GIS is a powerful tool for assisting in data integration and planning. This paper describes common uses of GIS by Network contractors as well as demonstrating the possibilities of GIS as a…

The purpose of this paper is to capture the pedagogical content knowledge (PCK) of university professors about quantum chemistry. More specifically, we aimed to identify and analyze relationships between specific PCK components, using an adapted version of the model of PCK of Magnusson "et al.". A sample of university professors (n = 6)…

Drawing on an ecological perspective, this paper reports on an investigation into the changes in one first-year college student's beliefs about English teaching and learning since his enrollment.

Microarray is a high throughput technology to measure the gene expression. Analysis of microarray data brings many interesting and challenging problems. This thesis consists three studies related to microarray data. First, we propose a Bayesian model for microarray data and use Bayes Factors to identify differentially expressed genes. Second, we…
