THE Institute for Mathematical Studies in the Social Sciences (IMSSS) has a long history of interest in research and development in computer-assisted instruction (CAl) in reading, most of that work directed by Professor Richard C. 1973). We have also studied, developed, and used a variety of audio systems in other work in CAL Most recently we have developed(More)
In this report we present a new approach to evaluation of curriculum. Many of us who have been engaged in curriculum reform efforts have been dissatisfied with the wait-ahd-see approach required when classical evaluation of a new curriculum is used. We have in mind evaluation by comparing pretests and posttests, with an analysis of posttest grade-placement(More)
the models are tested both for ability to predict final grade placement and for ability to describe all points observed throughout the year. Two of the simplest models, using only the most recent point and parameters estimated for the whole group, are best at prediction. The power function model with all parameters estimated individually for each student,(More)
We review recent developments in the study of excited baryon spectroscopy in lattice QCD. After introducing the basic methods used to extract masses from correlation functions, we discuss various interpolating fields and lattice actions commonly used in the literature. We present a survey of results of recent calculations of excited baryons in quenched QCD,(More)
THIS article describes a new technique for compressing linear-prediction (LP) coefficients by reducing both the redundancy of the coefficients of individual frames and the sequential redundancy of the coefficients in time, using interpolation and quantization of pseudo-formant parameters. In sections I and 2 of the article, the analysis procedure and(More)
l. Introduction In a previous paper (Suppes and Zanotti, 1976) we gave simple necessary and sufficient qualitative axioms for the existence of a unique expectation function for the set of extended indicator functions. As we defined this set of functions earlier, it is the closure of the set of indicator functions of events under function addition. In the(More)
Innovation to improve the quality of structure and process in health care organization is reported in this case example of change in an academic medical center. Interactive planning and the circular organization design concept were the driving principles and methods. This report presents the needs for and initial obstructions to change, planning and project(More)
