The Fourier transform is one of the most important mathematical tools in a wide variety of fields in science and engineering. In the abstract it can be viewed as the transformation of a signal in one domain (typically time or space) into another domain, the frequency domain. Applications of Fourier transforms, often called Fourier analysis or harmonic analysis, provide useful decompositions of signals into fundamental or "primitive" components, provide shortcuts to the computation of complicated sums and integrals, and often reveal hidden structure in data. Fourier analysis lies at the base...

Teacher Evaluation: Guide to Professional Practice is organized around four dominant, interrelated core issues: professional standards, a guide to applying the Joint Committee's Standards, ten alternative models for the evaluation of teacher performance, and an analysis of these selected models. The book draws heavily on research and development conducted by the Federally funded national Center for Research on Educational Accountability and Teacher Evaluation (CREATE). The reader will come to grasp the essence of sound teacher evaluation and will be able to apply its...

In the winter of 1996, after 4 years of planning and research, the Symposium on the Virtual Utility was held in Saratoga Springs, New York. It was sponsored by Niag ara Mohawk Power Corporation, Co-sponsored by CSC Index and the New York State Energy Research and Development Authority and hosted by Rensselaer Poly technic Institute, Troy, NY. The symposium sought to identify new areas of inquiry by presenting cutting-edge academic and practitioner research intended to further our understanding of the strategic, technologically-driven issues confronting the elec tricity production and...

In the decade of the 1970s, item response theory became the dominant topic for study by measurement specialists. But, the genesis of item response theory (IRT) can be traced back to the mid-thirties and early forties. In fact, the term "Item Characteristic Curve," which is one of the main IRT concepts, can be attributed to Ledyard Tucker in 1946. Despite these early research efforts, interest in item response theory lay dormant until the late 1960s and took a backseat to the emerging development of strong true score theory. While true score theory developed rapidly and drew the attention of...

This book presents a set of papers from the leading edge of current research on productivity analysis. The focus is on alternative forms of measurement, methods, and their implications. The book begins with a chapter by V. Corbo and J. de Melo comparing the effects of using different production frontier models for measuring technical efficiency when using census data. The second chapter (by H. Pesaran and R. Tarling) is a detailed analysi.s of measurement of labor and its variations over time. The next two chapters concern the measurement of capital. The first of these is written by M. F....

Major "paradigm shifts"-replacing one "world view" with another regarding what constitutes appropriate knowledge do not happen over night. Centuries usually intervene in the process. Even minor shifts admitting alternative world views into the domain of legitimate knowledge producing theory and practice-require decades of controversy, especially, it seems to us, in the field of education. It has only been in the last 20 years or so that the educational research community has begun to accept the "scientific" credibility of the qualitative approaches to inquiry such as participant observation,...

This book is about the practice of decision making by school principals and about ways to improve this practice by capitalizing on evaluation dimensions. Much has been written on decision making but surprisingly little on decision making in the school principalship. Much has been also written on evaluation as well as on evaluation and decision making, but not much has been written on evaluation in decision making, especially decision making in the principalship. This book presents two messages. One is that decision making in the principalship can be studied and improved and not only talked...

In an age that dictates accountability and verifiability of educational programs, institutions of higher education are called on to justify their programs. To meet these demands, there is a need for improved methods for the evaluation of teacher education programs. More importantly, there is a need for the development of methods and procedures to conduct continuous and on-going evaluation that can aid the process of program improvement. Many institutions have had difficulties in developing and implementing satisfactory systems for conducting needed evaluation. In recent years the standards...

I personally learned to know Ralph Tyler rather late in his career when, in the 1960s, I spent a year as a Fellow at the Center for Advanced Study in the Behavioral Sciences at Stanford. His term of office as Director of the Center was then approaching its end. This would seem to disqualify me thoroughly from preparing a Foreword to this "Classic Works. " Many of his colleagues and, not least, of his students at his dear Alma Mater, the University of Chicago, are certainly better prepared than I to put his role in American education in proper perspective. The reason for inviting me is, I...
