This thesis examines the use of a structured design methodology in the design of asynchronous circuits so that high level constructs can be specified purely in terms of signal exchanges and without the intrusion of lower level concepts. Trace theory is used to specify a multi-processor Forth machine at a high level then part of the design is further elaborated using trace theory operations to (insure that the behaviours of the lower level constructs will combine to give the high level specified behaviour without locking or other hazards. A novel form of threaded language to take advantage of the machine architecture is developed. At suitable points the design is tested by simulation. The stack element which is designed is reduced to an electric circuit which is itself tested by simulation to verify the design.

This study addresses the question “what is it like to be a gifted early college entrant?” Participants were eight college graduates between the ages of 23 and 45 who matriculated to college as full-time, degree-seeking students at age 16. This was a qualitative study conducted by open-ended interview and utilized narrative inquiry as a framework for the analysis. Participant responses were coded and analyzed using constant comparative method. Coded responses were grouped into 40 subcategories which were further collapsed into 7 overarching categories that provide a framework for understanding the experience of early college entrance: life story; being exceptional; understanding exceptionality through others’ experience; transition to college, academic preparation, performance, and experience; getting involved and pursuing interests; and social-emotional awareness and agency. These categories provide a picture of the milieu in which participants made the decision to enter college early. Results of this study suggest that participants experienced a milieu of educational experiences, including academic acceleration, and embedded social-emotional contexts that increased their academic self-concept and precipitated early college entrance. Despite failing to recognize their own giftedness and experiencing academic struggle, participants successfully completed college and embarked on meaningful careers. Interpreting giftedness as asynchronous development provides a framework for these results. The results of the present study suggest that while the native cognitive ability of a gifted early entrant might be sufficient to complete college, additional social-emotional supports are needed to fully realize the academic potential of gifted students.
