It is argued that dual-process theory has misconstrued the correspondence between words' spelling and their phonology. A subsymbolic alternative to dual-processing theory is presented that includes a clear role for the process of phonologic coding. The subsymbolic approach is developed around a covariant learning hypothesis. (SLD)

Identifies four components of a good predictive lossless image compression method: (1) pixel sequence, (2) image modeling and prediction, (3) error modeling, and (4) error coding. Highlights include Laplace distribution and a comparison of the multilevel progressive method for image coding with the prediction by partial precision matching method.…

Presents four principles for archive-based language research: maximum readability and minimum bias; consistent encoding for exhaustive computer search; systematic contrastiveness; and data comparability in elicitation, transcription and coding. Examples from existing computer archives illustrate these and other principles, and strategies are…

A model of word recognition is proposed that assumes that, when a word is encountered, the first available orthographic code activates all lexical entries that are positionally equivalent with that information (the word's "cohort"). The model is explained relative to encoding and the complex orthographic unit termed a wickelgraph. (SLD)

Gives examples of the use of Freire's notion of codes or generative themes in problem-posing literacy education. Describes how these applications expand Freire's conceptions by involving students in code production, including multicultural perspectives, and rethinking codes as representations. (SK)

Describes the history and major features of XML and TEI, discusses their potential utility for the creation of digital libraries, and focuses on XML's application in the humanities, particularly theater and drama studies. Highlights include HTML and hyperlinks; the impact of XML on text encoding and document access; and XML and academic…

Describes the cognitive steps a student should go through to be able to answer a chemical equilibrium question and investigates student responses to identifying particular symbols and words. (YDS)

Computer programming lends itself to automated assessment. With appropriate software tools, program correctness can be measured, along with an indication of quality according to a set of metrics. Furthermore, the regularity of program code allows plagiarism detection to be an integral part of the tools that support assessment. In this paper, we…

In 3 experiments, the authors tested performance in simple tone matching and classification tasks. Each tone was defined on location and frequency dimensions. In the first 2 experiments, participants completed a same-different matching task on the basis of one of these dimensions while attempting to ignore irrelevant variation in the other…

A study with students enrolled at an urban technical college compared learning of HTML coding across three Web-based program versions. One group received examples providing factual information about the source code (Facts group). A second group was presented with a step-by-step description of the source code (Procedures group). The third group was…

The number Pi has a rich and colorful history. The origin of Pi dates back to when Greek mathematicians realized that the ratio of the circumference to the diameter is the same for all circles. One is most familiar with many of its applications to geometry, analysis, probability, and number theory. This paper demonstrates several examples of how…

School principals have complex jobs. To better understand the work lives of principals, this study uses observational time-use data for all high school principals in Miami-Dade County Public Schools. This paper examines the relationship between the time principals spent on different types of activities and school outcomes including student…

The research reported in this paper is focused directly on assessing the validity of the "Teaching Knowledge about Reading and Reading Practices" (TKRRP) assessment. Following the recommendations of the Standards for Educational and Psychological Testing (APA/AERA, 1999), the authors see validation as a process of constructing an…

Problem-based learning (PBL) is a pedagogical method that challenges students to think intuitively, learn cooperatively in groups to seek solutions to real world problems. These problems are used as the building blocks to engage students' curiosity and initiate independent learning of subject matter. Authentic, alternative assessment plays a key…

This research evaluates websites from 200 "non-deviant" and 200 "deviant" non-profit organizations to better understand the relationship between the type of advocacy group and the visual imagery used for self-representation. Seventeen of 21 variables measured for this study found no difference between non-deviant and deviant non-profit…
