The pure Rasch model was compared with four modifications of the model in a number of different simulations in order to ascertain the comparative efficiencies of the parameter estimations of these modifications. Because there is always noise in test score data, some individuals may have response patterns that do not fit the model and their…

IN A STUDY AT THE UNIVERSITY OF TORONTO, CANADA, A SIMULATION MODEL WAS DEVELOPED TO AID INSTITUTIONAL PLANNING FOR THE UNDERGRADUATE LEVEL OF HIGHER EDUCATION. BY DEVELOPING A CONCEPTUAL FRAMEWORK FOR THE QUANTIFICATION OF RESOURCE MANAGEMENT, THE AUTHORS EXPLORE THE EDUCATION FUNCTION IN TERMS OF THE FACTORS OF CONTROL AFFECTING DECISION MAKING…

THE PURPOSE OF THE PROJECT WAS TO REVIEW THE TEST AND EVALUATION LITERATURE ON DOCUMENT RETRIEVAL SYSTEMS, TO IDENTIFY THE METHODOLOGICAL PROBLEMS, AND TO DEVELOP A SET OF RECOMMENDATIONS FOR RESEARCHERS IN THE FIELD. TWO BASIC TOOLS WERE DEVELOPED TO AID IN THE DESCRIPTION AND EVALUATION OF THE STUDIES REVIEWED. THE FIRST TOOL WAS A DESCRIPTIVE…

OPEN AND CLOSED LOOP SIMULATION IS DISCUSSED FROM THE VIEWPOINT OF RESEARCH AND DEVELOPMENT IN TRAINING TECHNIQUES. AREAS DISCUSSED INCLUDE--(1) OPEN-LOOP ENVIRONMENTAL SIMULATION, (2) SIMULATION NOT INVOLVING PEOPLE, (3) ANALYSIS OF OCCUPATIONS, (4) SIMULATION FOR TRAINING, (5) REAL-SIZE SYSTEM SIMULATION, (6) TECHNIQUES OF MINIATURIZATION, AND…

THE "CASE" PROGRAM WAS DEVELOPED TO PROVIDE A VEHICLE FOR UNDERSTANDING THE PSYCHOLOGICAL PROCESSES INVOLVED IN CONCEPT LEARNING BY MEANS OF COMPUTER SIMULATION TECHNIQUES. BECAUSE THE MAJORITY OF PUBLISHED "SIMULATION OF CONCEPT LEARNING" PROGRAMS PROVIDED FEW INSIGHTS INTO THE LEARNING PROCESS, THE "CASE" PROGRAM…

A MATHEMATICAL MODEL OF ESTABLISHED AND INDUSTRIALLY VALIDATED LEARNING AND FORGETTING THEORIES IS OUTLINED, AND A COMPUTER-EXECUTED HEURISTIC ALGORITHM FOR SELECTING THE BEST SCHEDULE FOR SUBJECT PRESENTATION IS GIVEN. FUNDAMENTAL PARAMETERS OF THE MODEL INCLUDE EDUCATION POTENTIAL, TYPE OF SUBJECT MATTER, TYPE OF LEARNER, TEACHING METHODS, AND…

A SERIES OF SEVEN STUDIES WAS CONDUCTED CONCERNING FACTORS IN BRANCHING (PROGRAMED INSTRUCTION), USING SIMULATION TECHNIQUES OF PICTORIAL OR AUDIO STIMULUS FRAMES AND OF PERFORMANCE RESPONSES. USING VARIATIONS OF THREE OF THE FOUR PROGRAMS ORIGINALLY WRITTEN TO INSTRUCT COLLEGE JUNIORS AND SENIORS IN THE USE OF THE UNIVERSITY LIBRARY, THE STUDIES…

Types of assessment, five assessment techniques, and issues related to assessing experiential learning in career education are discussed. The following six points should be considered before an assessment program begins: (1) assumptions; (2) goals; (3) outcomes; (4) learning environment; (5) role of assessors; and (6) focus. Two basic types of…

A study was conducted by the Air Force to determine the extent to which takeoff/landing skills learned in a simulator equipped with a night visual system would transfer to daytime performance in the aircraft. A transfer-of-training design was used to assess the differential effectiveness of simulator training with a day versus a night…

Presented are the skills needed for facilitating and linking. A role play experience provides the opportunities for issues and concerns to be made explicit. The role play process permits conflict points to be made explicit and to be specified in a psychologically safe context. Because the role play is "make believe," there is permission…

Described is the computer simulation program "PH." The program consists of three different laboratory investigations dealing with the pH specificity of enzymes. The purpose of the program is to enable tenth- to twelfth-grade students to determine a possible explanation for pH specificity in an experimental, but mathematical, fashion.…

Three computer programs are presented that allow the high school student to explore and understand the physical forces involved in orbital flight at a greater depth than is usually possible. For each program, introductory material is given including the physics and mathematics involved. This is followed by the computer program in BASIC language.…

THE LITERATURE OF ERGONOMICS, OR BIOTECHNOLOGY, IS CLASSIFIED INTO 15 AREAS--METHODS, SYSTEMS OF MEN AND MACHINES, VISUAL AND AUDITORY AND OTHER INPUTS AND PROCESSES, INPUT CHANNELS, BODY MEASUREMENTS, DESIGN OF CONTROLS AND INTEGRATION WITH DISPLAYS, LAYOUT OF PANELS AND CONSOLES, DESIGN OF WORK SPACE, CLOTHING AND PERSONAL EQUIPMENT, SPECIAL…

IN THIS STUDY, A COMPUTER-CONTROLLED PATIENT SIMULATOR (SIM ONE) WAS DESIGNED, CONSTRUCTED, AND TESTED FOR THE TRAINING OF ANESTHESIOLOGY RESIDENTS AT THE UNIVERSITY OF SOUTHERN CALIFORNIA SCHOOL OF MEDICINE. THE TRAINING INVOLVED THE DEVELOPMENT OF SKILL IN ENDOTRACHEAL INTUBATION. THE EXPERIMENT INVOLVED 10 ANESTHESIOLOGY RESIDENTS. FIVE WERE…

The lack of tested models of the instructional process is the prime hindrance to significant management science in educational research. The nature of education, with long timelags between ultimate performance and present activity, makes the modeling most difficult. This paper reports on one of several efforts which have been made to develop…
