In this study the authors have looked at the use of interactive whiteboards (IWBs) in Mexico from a linguistic anthropological perspective. Twenty lessons were video recorded to compare the use of IWBs and traditional boards in different areas of the curriculum in primary schools. Data were analysed as a set of sequenced communicative events in…

According to parallel distributed processing (PDP) models of visual word recognition, the speed of semantic coding is modulated by the nature of the orthographic-to-semantic mappings. Consistent with this idea, an ambiguity disadvantage and a relatedness-of-meaning (ROM) advantage have been reported in some word recognition tasks in which semantic…

It seems that everyone is talking about Web 2.0. This new vision of the Web enables greater interactivity, more user control of information, radical personalization, the development of online communities, and more democratic management of information. Supporting technologies include blogs, wikis, RSS, podcasts, tagging, XML, and Web services.…

The cognitive constructions coding system (CCCS) was designed for coding client's expressed problem constructions on four dimensions: intrapersonal-interpersonal, internal-external, responsible-not responsible, and linear-circular. This study introduces, and examines the reliability and validity of, a modified version of the CCCS--a version that…

Background: Previous models of the effects of feedback account for lower-order learning outcomes but do not adequately describe experimental findings for higher-order learning. Aims: Based on a connectionist model of feedback effects, this investigation aims to show that feedback that allows only one learner response facilitates…

Maternal elaboration and autonomy support during reminiscing facilitate middle-class children's autobiographical narrative skills. In this study, low-income Hispanic, White, and Black mothers' elaboration and autonomy support in reminiscing were examined in relation to children's joint and independent autobiographical narratives and engagement.…

More information is becoming available about Asperger Syndrome (AS), especially regarding the educational needs of children. There is a lack of available information, however, regarding adults with AS, particularly women. Five women with AS participated in this qualitative research study over a two-year period. The purpose was to investigate and…

A research-based program was designed for the improvement of decoding and encoding nonverbal cues as they are important aspects of successful communication and teaching. To extend the scientific base of the program, six correlational studies (N=784) investigated relationships between nonverbal skill and personality dimensions. Low non-significant…

This paper describes a project carried out by the first author, an academic in special education, with the other authors, teachers of students with severe disabilities. It aimed to explore the application of the New South Wales (NSW) model of pedagogy, derived from authentic pedagogy, to the education of students with severe intellectual…

Building on 2 previous studies (B. R. Ekstrand, 1967; B. R. Ekstrand, M. J. Sullivan, D. F. Parker, & J. N. West, 1971), the authors present 2 experiments that were aimed at characterizing the role of retroactive interference in sleep-associated declarative memory consolidation. Using an A-B, A-C paradigm with lists of word pairs in Experiment 1,…

The development of a coding scheme to identify the function of each conversational turn within episodes of conflict in a peer tutoring setting is described, and the scheme, based on Cohen's kappa analysis, is presented. Although 15 codes were developed for the initial effort, 7 codes were finally used to reflect each utterance as: (1) agreement;…

This CD-ROM contains a separate electronic codebook for each of the following National Center for Education Statistics data sets: (1) B94, Baccalaureate and Beyond 1993-94 (restricted); (2) B97, Baccalaureate and Beyond 1993-97 (restricted); (3) BP4, Beginning Postsecondary Students 1990-94 (restricted); (4) FAC, 1992-93 National Student of…

Introduces this issue, which contains papers from the 1991 Data Compression Conference, and defines data compression. The two primary functions of data compression are described, i.e., storage and communications; types of data using compression technology are discussed; compression methods are explained; and current areas of research are…

Describes a modified frequency-sensitive self-organization (FSO) algorithm for image data compression and the associated VLSI architecture. Topics discussed include vector quantization; VLSI neural processor architecture; detailed circuit implementation; and a neural network vector quantization prototype chip. Examples of images using the FSO…

The second of two articles on recursive programing techniques focuses on pseudocoding of recursive processes, evaluation and encoding of recursive procedures, and evaluation and encoding of recursive functions. The translation of recursive relations in mathematics to recursive functions is also examined, and an example is given. (12 references)…
