Concept mapping in college-level physics was investigated. The study was carried out in three parts. First, an attempt was made to validate concept mapping as a method of evaluating student learning at the junior college level (ages 16-21). Several measures…

A methodology was developed in this study for identifying the cognitive, pedagogical, and computational characteristics of computer-based learning environments. The characterization of the cognitive and pedagogical features was achieved by decomposing the learning environments into episodes which were composed of…

Additive and multiplicative statistical models in epidemiology invoke different assumptions regarding exposure-outcome relationships. While either may seem to provide an adequate fit in small data sets, a comparative parameter based on the correct set of assumptions will be more stable…

The development of language in physically handicapped individuals using augmentative and alternative communication (AAC) systems has not been described. Therefore our understanding of the role of AAC language encoding limitations in the development of syntax is limited. This study examined…

A design for a unified model based on the hypermedia paradigm is proposed as a means to a better synergism of the functionalities of different knowledge manipulation tools. A survey of past and present hypermdia systems has been achieved, and…

This thesis explores the use of randomized, performance-based search strategies to improve the generalization of an automatic speech recognition system based on hidden Markov models. We apply simulated annealing and random search to several components of the system, including phoneme…

The application of scientific principles in diverse science domains is widely regarded as a hallmark of expertise. However, the role of basic science knowledge and principles in clinical medicine is the subject of considerable controversy. The study examined the understanding…

The complete design of many electromagnetic devices requires the solution of a coupled problem. Typically, the coupling is in the form of magnetic/thermal, magnetic/structural, magnetic/electronic, or possibly a combination of several disciplines. Computer based tools exist for many of these…

We study the problem of classifying stop and nasal consonants in continuous speech independently of the speaker. We consider some acoustic parameters computed from the auditory spectrogram, and other parameters computed from the speech waveform. The classification algorithm uses a…

The larger issue of the relationship between theory, fiction and experience provides the backdrop for a study of constructions of home in Toni Morrison's The Bluest Eye and Beloved. Feminist standpoint theory contends that knowledge is socially and historically constructed.…
