Data compression is the art of using encoding techniques to represent data symbols using less storage space compared to the original data representation. The encoding process builds a relationship between the entropy of the data and the certainty of the system. The theoretical limits of this relationship are defined by the theory of entropy in…

In this paper, we give two unexpected applications of a Hamming code. The first one, also known as the "Hat Problem," is based on the fact that a small portion of the available code words are actually used in a Hamming code. The second one is a magic trick based on the fact that a Hamming code is perfect for single-error correction.

Hari and Jousmaki (1996) found that motor activity is initiated more efficiently in response to stimuli located on the responding limb as opposed to near the limb. Our research investigated the basis for this difference in spatial coding. We conducted 8 experiments using virtual reality to manipulate the visual feedback resulting from limb…

This paper contrasts two structural accounts of psychological similarity: structural alignment (SA) and Representational Distortion (RD). SA proposes that similarity is determined by how readily the structures of two objects can be brought into alignment; RD measures similarity by the complexity of the transformation that "distorts" one…

This article presents a study conducted by Cornelia Yarbrough and Jennifer Whitaker titled "Analysis of Reviewer Comments About Quantitative Manuscripts Accepted by the "Journal of Research in Music Education"." The study aims to analyze reviewers' comments for quantitative manuscripts with regard to the following categories: section discussed…

A fundamental claim associated with parallel distributed processing (PDP) theories of cognition is that knowledge is coded in a distributed manner in mind and brain. This approach rejects the claim that knowledge is coded in a localist fashion, with words, objects, and simple concepts (e.g. "dog"), that is, coded with their own dedicated…

Young typically developing children can reason about abstract depictions if they know the intention of the artist. Children with autism spectrum disorder (ASD), who are notably impaired in social, "intention monitoring" domains, may have great difficulty in decoding vague representations. In Experiment 1, children with ASD are unable to use…

In planning educational technology initiatives, the concerns of many stakeholders are typically taken into account, including the concerns of administrators, teachers, parents, and employers. The perspective of students are recognized as valuable, but not often queried or considered. This paper explores the opinions of K-12 students about a…

The latest national educational policy in the People's Republic of China calls for comprehensive educational reforms aimed at building the foundation for a modern learning society throughout China over the next 10 years. This research examines school leaders' efforts to implement school improvement initiatives that directly respond to the policy's…

High school students with autism spectrum disorder (ASD) often struggle in the complex social and academic secondary environment. Current literature suggests postsecondary success is limited for adults with ASD, but little is known about the high school experiences of individuals with ASD that may be impacting their postsecondary outcomes. Focus…

One of the field's most enduring problems is the overrepresentation of students of color in special education. A less acknowledged challenge is the overrepresentation of students with disabilities in juvenile incarceration. Quantitative studies have documented the overrepresentation of students with disabilities in juvenile justice. Yet,…

This study investigates pre-service teachers' TPACK development in a secondary science teacher education program that combined a content-specific technology integration course with extensive field experience. Both quantitative and qualitative data were collected. Quantitative data were collected through a pre-post administration of the…

Social networking tools offer opportunities for innovative, participative pedagogical practice within traditional institutional frameworks. However, tensions continue to develop within this space: between creativity and security, personal and professional identity, privacy and openness. We argue that iSchools are uniquely positioned to create…

As part of the process of redesigning an integrated general and special teacher education program to prepare candidates to meet the needs of culturally and linguistically diverse students, researchers engaged a series of focus groups with current candidates, recent graduates, and partner school personnel. Data presented in this paper identified…

This paper is an attempt to explore the interaction discourse of second language undergraduate learners in the online peer review process of a writing classroom in Hong Kong. Specifically, the writer sought to investigate the types of online discourse learners have in the peer discussions on their writing, and to examine the role of explicit…
