The purpose of this article is to provide the necessary tools for institutional researchers to conduct a logistic regression analysis and interpret the results. Aspects of the logistic regression procedure that are necessary to evaluate models are presented and discussed with an emphasis on cutoff values and choosing the appropriate number of…

In this paper we explore the relationship between learning gains, measured through pre-assessment and post-assessment, and engagement in scientific argumentation. In order to do so, this paper examines group discourse and individual learning during the implementation of NASA Classroom of the Future's BioBLAST![R] (BB) software program in a high…

The authors provide a review and critique of 82 empirical investigations conducted in the United States on teacher preparation for reading instruction. These studies were chosen from a pool of 298 based on the authors' coding of research quality indicators. Applying an inductive paradigmatic analysis of the 82 studies, this review suggests that in…

This study examined the degree of acceptance of qualitative research by medical trainees and physicians, and explored the causes for any differences in their support of qualitative versus quantitative research. Thirty-two individuals at four levels of medical training were studied. Eight philosophers of science served for construct validation.…

Research shows both benefits and challenges of online discussion as a collaborative learning activity. Online discussion is especially challenging for novice college students who have limited metacognitive skills as well as limited knowledge of the subject domain. With limited metacognitive skills, it can be challenging for novice students to…

The website "Active Listening" was developed within a larger project--"Interactive Web-based training in the subtleties of communication and active listening skill development." The Active Listening site aims to provide beginning counseling psychology students with didactic and experimental learning activities and interactive tests so that…

The investigator compared the linguistic characteristics of Spanish and English language samples taken from English language learners (ELLs) diagnosed with an academic learning disability (LD) and ELLs in general education to determine if the errors and characteristics of their language use differ. There was a statistically significant difference…

The present study investigated the associations of Korean mothers' attention regulation and referential speech during play with their toddlers' language and play development. The play interaction between mothers (n = 42) and their toddlers aged between 13 and 23 months was videotaped during home visits. Maternal behavior in regulating their…

This paper describes two international standards for the representation of the names of languages. The first (ISO 639-1), published in 1988, provides two-letter codes for 136 languages and was produced primarily to meet terminological needs. The second (ISO 639-2) appeared in late 1998 and includes three-letter codes for 460 languages. This list…

Discussion of contrast enhancement techniques focuses on the use of histogram equalization with a data compression technique, i.e., tree-structured vector quantization. The enhancement technique of intensity windowing is described, and the use of enhancement techniques for medical images is explained, including adaptive histogram equalization.…

Discusses various aspects of visual communication--light, semiotics, codes, photography, typography, and visual literacy--within the context of the communications technology area of technology education. (SK)

Results of three experiments confirmed previous findings that in a moving word task, prereaders 3 to 5 years of age judge as if the meaning of a written word changes when it moves from a matching to a nonmatching toy (e.g., when the word ''dog'' moves from a dog to a boat). We explore under what circumstances children make such errors, we identify…

According to several current models of short-term memory, items are retained in order by associating them with positional codes. The models differ as to whether temporal oscillators provide those codes. The authors examined errors in recall of sequences comprising 2 groups of 4 consonants. A critical manipulation was the precise timing of items…

Service learning experiences hold the potential to significantly influence participants' view of cultures other than their own. This qualitative study examines how service learning affects preservice teachers' attitudes about working with students from diverse backgrounds. Two groups of preservice teachers enrolled in a reading methods course…

Targeted email attacks to enable computer network exploitation have become more prevalent, more insidious, and more widely documented in recent years. Beyond nuisance spam or phishing designed to trick users into revealing personal information, targeted malicious email (TME) facilitates computer network exploitation and the gathering of sensitive…
