This paper presents a concept for designing low-cost therapeutic training with biofeedback and virtual reality. We completed the first evaluation of a prototype--a mobile learning application for relaxation training, primarily for adolescents suffering from tension-type headaches. The system delivers visual experience on a head-mounted display. A…

In this paper, we present a data-based user modeling framework that uses both unsupervised and supervised classification to build student models for exploratory learning environments. We apply the framework to build student models for two different learning environments and using two different data sources (logged interface and eye-tracking data).…

The two purposes of this paper are to provide a SAS IML macro that performs loglinear smoothing and to apply this macro to loglinear smoothing problems that have not been extensively discussed in the test-equating literature. The SAS macro is demonstrated on univariate, bivariate, and trivariate smoothing problems. The univariate and bivariate…

An interactive computer-based system for assisting investigators in the use of Bayesian analysis using the two parameter normal model is described. An important feature of this program is that it interacts with the investigator in the English language; he need not be familiar with computer languages or with the internal workings of the computer.…

A review of the literature and of currently available computer programs for the use of log-linear models in analysis of qualitative data is presented, and two types of log-linear models and procedures for investigating both types are outlined. (MSE)

A simple and effective model for forecasting freshman enrollment during the application period is presented step by step. The model requires minimal and readily available information, uses a simple linear regression analysis on a personal computer, and provides updated monthly forecasts. (MSE)

This report discusses the analysis of selected factors related to public school enrollment and describes the development of a model for projecting student enrollment using a systems analysis approach. Chapter 1 discusses the purpose of the study, the techniques employed in the study, and the organization of the report. Chapters 2 and 3 provide an…

The four purposes of this study were: (1) To compare two versions of a tailored testing model similar to one suggested by Kalisch (1974); (2) To identify levels of the variables within the two versions, which produce an efficient tailored testing procedures; (3) To compare, within each version, the results obtained when employing relatively small…

Two tailored testing models, specifying procedures by which the correctness of examinees' responses to a fixed number of test items are predicted by presenting as few items as possible to the examinee, were compared for their efficiency. The models differ in that one requires reconsideration of each prediction whenever additional information is…

A decision support application based on the Markov analytic model is described, and its use in the formation of policy concerning reduction in force and work force distribution is illustrated through the comparative modeling of two personnel management policies. (MSE)

Presented are variables and conditions for design of a computer-based adaptive instructional system. The design strategy uses Bayes' theory of conditional probability to determine an instructional sequence according to individual student characteristics and needs. The adaptive strategy uses prior estimates based on student pretask and on-task…

Bloom's taxonomy of the cognitive domain consists of six major levels: Knowledge, Comprehension, Application, Analysis, Synthesis, and Evaluation. The purpose of this study is to construct a quantitative causal model for a set of tests designed to operationally define these six levels in order to further explore the validity of the cumulative…

The value of microcomputer modeling tools and spreadsheets to help college institutional researchers analyze proposed capital projects is discussed, along with strengths and weaknesses of different software packages. Capital budgeting is the analysis that supports decisions about the allocation and commitment of funds to long-term capital…

A linear regression model was used to select items from a pool of 700 arithmetic word problems to be used in a computer-assisted mathematics curriculum for elementary school students. The experimental procedure first involved a stepwise linear regression analysis of a student's performance over a set of 25 problems. The probability correct for…

This guide is intended for local- and state-level vocational education administrators, planners, and evaluators who are responsible for making program planning and evaluation findings and decisions geared toward increasing program relevance. The method differs from more traditional approaches in its heavy reliance upon the selection and…
