Intelligent tutoring systems are adaptive learning environments designed to support individualized instruction. The adaptation embedded within these systems is often guided by user models that represent one or more aspects of students' domain knowledge, actions, or performance. The proposed project focuses on the development and testing of user…

As the availability of high-throughput data-collection technologies, such as information-sensing mobile devices, remote sensing, internet log records, and wireless sensor networks has grown, science, engineering, and business have rapidly transitioned from striving to develop information from scant data to a situation in which the challenge is now…

Since problems associated with the statistical methodology of educational research are becoming increasingly important, this paper examines a subset of problems associated with the analysis and interpretation of aggregated data. Two major questions arise: (1) if a researcher knows the level (e.g., individual, teacher/classroom, school, school…

The teaching function is examined to determine an improved budgetary planning and control system as well as comparisons across universities and polytechnics. The inputs, outcomes and processes of the teaching function are identified and defined, with available data collected and measured with reference to those defined variables and parameters.…

The National Longitudinal Study of the High School Class of 1972 (NLS) is a large-scale longitudinal survey effort. The current data tapes contain base-year (1972) survey data integrated with first follow-up (1973) survey data. The base-year data consist of responses to a Student Questionnaire, the results of an ability test, and information from…
