Using case study methodology, this paper examines how pairs of first-time high school student users navigated through a multimedia geography CD-ROM together. Discusses coding methods for student activity; student interaction; dialog analysis; multimedia literacy; and further research needs. (Author/LRW)

Fifty families participated in mother-infant and father-infant still-face interaction at infant ages 3 and 6 months as part of a study of affect in early parent-infant relationships. Infants' positive and negative affect and parents' positive affect and physical play were coded from videotapes. Consistent with previous research, during the normal…

This article describes Cryptography, defined as the science of encrypting and deciphering messages written in secret codes, it has played a vital role in securing information since ancient times. There are several cryptographic techniques and many make extensive use of mathematics to secure information. The author discusses an activity built…

The article reports the results of a usability study of an EAD interface. Findings indicate that subjects had trouble understanding archival terminology and how best to search for information in finding aids. Furthermore, they were not familiar with the structure or contents of finding aids. In addition to building interfaces that minimize…

This study investigated the encoding of syllable boundary information during speech production in Dutch. Based on Levelt's model of phonological encoding, we hypothesized segments and syllable boundaries to be encoded in an incremental way. In a self-monitoring experiment, decisions about the syllable affiliation (first or second syllable) of a…

Purpose: This study examined whether child speakers of Southern African American English (SAAE) and Southern White English (SWE) who were also perceived by some listeners to present a Cajun/Creole English (CE) influence within their dialects produced elevated rates of 6 phonological and 5 morphological patterns of vernacular relative to other…

This article investigates how culture shapes instruction in a bilingual early care and education program serving migrant and seasonal farm worker families in rural Wyoming. Interviews with eight early childhood teachers as well as classroom observations were conducted. The investigation is framed around the following research question: How does…

An ethnographic study documented and analyzed the idiosyncratic symbols kindergarten children employ to encode their experiences in the domains of mathematics, music, and visual art, in order to identify any patterns in use and meaning. In the area of mathematics, children were given common objects and asked to sort them. Four categories of…

The purpose of this study was to examine the effect that coding (black and white, and color) and testing mode (visual/verbal) has on the achievement of students categorized as field independent (FID)/field dependent (FD) learners. One hundred eighty-three students enrolled in basic college level educational psychology courses were classified as…

This paper examines the dual coding hypothesis, a model of the coding of visual and textual information, from the perspective of a mass media professional, such as a teacher, interested in accurately presenting both visual and textual material to a mass audience (i.e., students). It offers an extension to the theory, based upon the various skill…

This document consists of the first two volumes of a new annual serial devoted to surveying some of the important developments in the mathematical sciences in the previous year or so. Mathematics is constantly growing and changing, reaching out to other areas of science and helping to solve some of the major problems facing society. Volumes 1 and…

Focusing on gender issues in the visual text, this paper describes one stage of a post structural analysis of "Square One TV" (SOTV), a program originally designed to provide instruction in mathematics for 8- to 12-year-old viewers which now emphasizes changing their attitudes toward mathematics. Post structural textual analysis was used…

This paper proposes a design framework for constructing Digital Rights Management (DRM) that enables learning objects in legal usage. The central theme of this framework is that any design of a DRM must have theories as foundations to make the maintenance, extension or interoperability easy. While a learning objective consists of learning…

Responding to the rapid development and often prohibitive costs of new classroom instruction technology, a group of interested faculty at Harford Community College (HCC), in Maryland, formed three Interactive Video (IV) Teams to explore the possibilities of using existing computer hardware and software at the college for interactive video…

This study is, as an inquiry into the effectiveness of discussion leadership taxonomy, designed to help online discussion leaders support and facilitate discussions conducted by undergraduates. Participants were approximately two hundred preservice undergraduate students taking an Introduction to Educational Technology course. Each week students…
