Although numerous studies have demonstrated different ways that augmented reality (AR) can assist students to understand the learning content via contextualised visualisation, less explored is its effect on collaborative problem-solving (CPS) in computer programming. This study aims to investigate how AR affects a CPS in a programming task. We…

We discuss the real-time scoring logic for a self-administered oral reading assessment on mobile devices (Moby.Read) to measure the three components of children's oral reading fluency skills: words correct per minute, expression and comprehension. Critical techniques that make the assessment real-time on-device are discussed in detail. We propose…

Recent rapid malware growth has exposed the limitations of traditional in-host malware-defense systems and motivated the development of secure virtualization-based solutions. By running vulnerable systems as virtual machines (VMs) and moving security software from inside VMs to the outside, the out-of-VM solutions securely isolate the anti-malware…

This report reflects a multi-year collaborative effort between the New Media Consortium (NMC) and the eLearn Center of the Universitat Oberta de Catalunya to help inform Iberoamerican educational leaders about significant developments in technologies supporting teaching, learning, and research in tertiary education. The report was produced to…

Purpose: This paper aims to present the semantic content identifier (SCI), a permanent identifier, computed through a linear-time onion-peeling algorithm that enables the extraction of semantic features from a text, and the integration of this information within the permanent identifier. Design/methodology/approach: The authors employ SCI to…

The New Media Consortium's Horizon Project is an ongoing research project that seeks to identify and describe emerging technologies likely to have a large impact in education and other industries around the world over a five-year time period. The chief products of the project are the "Horizon Reports", an annual series of publications…

There is no one universal definition of the term "computer literacy," which, in fact, is used so generally that people often preface references to microcomputers in education with their own definitions of computer literacy. The term is organized semantically in a variety of ways, and central to this semantic organization is a problem of…

Reports on the development of a prototype computerized abstractor's assistant called TEXNET, a text network management system. Features of the system discussed include semantic dependency links; displays of text structure; basic text editing; extracting; weighting methods; and listings of frequent words. (Contains 25 references.) (LRW)

This paper describes PAL--a new computer language. It is used as a pedagogical vehicle in an undergraduate subject called "Programming Linguistics." This subject is designed primarily for sophomores who anticipate a major professional interest in computer science and has two objectives. The first is to study linguistic constructs for the…

A study to develop a methodology for discovering how one important notion or semantic category, "frequency of occurrence," is expressed in words, phrases, or other linguistic devices in academic English began with a search for devices expressing that notion, by analyzing text from a news magazine, a New Zealand geography textbook, and a…

The purposes of this study were to determine the nature of human semantic memory and to obtain knowledge usable in the future development of computer systems that can converse with people. The work was based on a computer model which is designed to comprehend English text, relating the text to information stored in a semantic data base that is…

Noting that expert computer systems respond to various contexts in terms of knowledge representation, this paper explains that heuristic rules of production, procedural representation, and frame representation have been adapted to such areas as medical diagnosis, signal interpretation, design and planning of electrical circuits and computer system…

This article discusses ways in which vocabulary building can be simplified for the student of Russian. Computer analysis of text vocabulary can assist in selecting words to be learned and assessing the relative difficulty of texts for both students and teachers. (CHK)

A 2-year project to develop a dictionary of modern Nepali is described. The Nepali-English dictionary was designed to include high-frequency vocabulary and to treat entries thoroughly, including associated collocations, semantic and/or grammatical restrictions, and other information essential to their use in sentences. Contents include 3,642 main…

An obstacle in Natural Language understanding is the existence of lexical gaps, i.e. words or word senses that are not in the lexicon of the system. This thesis describes the implementation of MURRAY, a learning mechanism which infers the properties of a new lexical item from its syntactical environment and infers its meaning based on context and…
