The "gold standard" for evaluating human immunodeficiency virus (HIV) prevention programs is a partner-by-partner sexual behavior assessment that elicits information about each sex partner and the activities engaged in with that partner. When collection of detailed partner-by-partner data is not feasible, aggregate data (e.g., total…

Methodological and political issues arise during the designing, conducting, and reporting of campus-climate studies for LGBT students. These issues interact; making a decision about a methodological issue (e.g., sample size) has an impact on a political issue (e.g., how well the findings will be received). Ten key questions that must be addressed…

English teaching in Colombian primary schools became a requirement because of the promulgation of the Law of Education in 1994. Taking into account that this decision produced some difficulties in the schools, a study was conducted to diagnose the state of English language teaching in primary schools in Pasto, Colombia. Data were gathered through…

In this paper, we present a data-based user modeling framework that uses both unsupervised and supervised classification to build student models for exploratory learning environments. We apply the framework to build student models for two different learning environments and using two different data sources (logged interface and eye-tracking data).…

Exclusionary school discipline results in students being removed from classrooms as a consequence of their disruptive behavior and may lead to subsequent suspension and/or expulsion. Literature documents that nondominant students, particularly Black males, are disproportionately impacted by exclusionary discipline, to the point that researchers…

This article presents a fairly quick, easy way to decide what size sample is needed for a survey, given a desired level of confidence and degree of accuracy. The method proposed will work on any multiple response instrument. A technical mathematical explanation is also included. (GK)

One in five students report experimenting with tobacco before the age of 13 and most prevention efforts take place in the school setting. This study measures the effect of a single-lesson tobacco prevention curriculum, conducted by a health education center, focusing on knowledge of tobacco, ability to identify refusal techniques, and intent not…

This article analyzes the attraction of stimulation produced by a visuotactile sensory substitution device, which was designed to provide optical information to infants who are blind via a tactile modality. The device was first tested on sighted infants, to demonstrate that this type of stimulation on the abdomen is pleasant and rewarding in…

The mixed methods case study described and analyzed the 2004-2006 district-based principal preparation programs in Virginia. This dissertation explored goals stated in proposals for funding as well as program director and program completer perceptions of goals, content, processes, and outcomes for the 10 principal preparation programs that stemmed…

This paper analyzes pedagogic practice in primary and secondary Singaporean English classrooms in terms of dialogicity. The dominant interactional patterns in Singaporean English classrooms are initiation-response-evaluation (IRE), whole class lecture and individual seatwork in which the students give either one word answers or remain silent.…

Describes the new design for the National Assessment of Educational Progress. Changes include a biennial schedule, expanded sampling, and balanced--incomplete spiralling of exercises and variables to permit the estimation of intercorrelations. Changes should improve the interpretability, comparability, timeliness, and policy relevance of the data.…

Our study compared the quantitative and qualitative outcomes associated with course evaluations collected over the Internet with those collected using a paper-and-pencil method. We randomly assigned students to 1 of the 2 different formats. There was no significant difference in quantitative student responses based on administration method, but…

Regardless of the related discipline, students in statistics courses invariably have difficulty understanding the connection between the numerical values calculated for end-of-the-chapter exercises and their usefulness in decision making. This disconnect is, in part, due to the lack of time and opportunity to actually design the experiments and…

Introduction: Mentoring is a central component of professional development. Evaluation of "successful" mentoring programs, however, has been limited and mainly focused on measures of satisfaction with the relationship. In today's environment, mentoring programs must produce tangible outcomes to demonstrate success. To address this issue,…
