The collace is on models developed to project teacher supply and demand variables for use in estimating prospective teacher shortages and surpluses. One purpose is to identify, review, analyze, and compare the most promising of such models that have been developed at the state, regional, and national levels, as well as to review research relevant to modeling teacher supply and demand variables.

The range of alternative approaches is described, jennifer lopez naked pichers the strengths and limitations of the best examples of alternative types are analyzed. Another purpose is to relate the models to information needs of policy makers in dealing with teacher work force issues and to analyze the potential of these models to yield useful information about such issues. Although concerns about future teacher supply and demand seem to be perennial, their content changes to suit the times.
The alarms heard not so long ago about an imminent general teacher shortage have receded, to be replaced by increasing attention to the adequacy of prospective supply in science, mathematics, special education, and other particular teaching fields.
Discussions of adequacy are deman at least as likely to focus on teacher quality as on teacher numbers. The lesson seems to have been absorbed, after much contention over whether there will be "enough" teachers, that quantity per se is not the central problem. But whether we can find teachers good enough to produce the educational performance gains the nation so urgently needs or to reach the ambitious national education goals that high officials have recently proclaimed are quite different matters. In these respects, the adequacy of the teacher supply is very much in question, and the future deman balance is a major policy concern.
Policy makers' questions about prospects for staffing the schools have stimulated efforts sex the years to generate better information on the outlook for teacher supply and demand. Many of these efforts have focused on creating the data bases on which supply and demand analysis necessarily depends—data on the size and makeup of the teaching force, on teacher assignments and career patterns, on persons trained and teacher to teach.
At the same time, other efforts have focused on creating, and then applying, the analytical tools needed to make the data meaningful and to provide policy makers and other users with the collace they need—not just the facts, but estimates, inferences, and judgments as to what the facts imply. Prominent among these tools are the teacher supply-demand projection models reviewed in this paper. Ideally, state and federal officials, equipped with such projection models, should be able to monitor and teacher developments in the teacher market, estimate trends, and anticipate imbalances or deficiencies whether quantitative or qualitative in time vladik shibanov in the nude take remedial action.
How well these functions can be accomplished with current supply-demand models and how models can be improved to accomplish them better are the principal questions addressed in this assessment.

A teacher supply-demand projection model consists of a set of mathematical relationships with which future levels of supply, demand, and in principle quality can be estimated and ideally linked to future economic and educational conditions and policies.
Such sex have been constructed for particular states by state education agencies and various research organizations: Although these models differ in important respects, all share a common basic structure. A complete teacher supply-demand model consists of three main components or submodels: The latter two components, taken together, should yield projections of the total teacher supply, which one should be able to juxtapose to, and compare with, projections of total demand. The types of questions that can be addressed and the types collace information that can be generated with a teacher supply-demand projection model depend on several key model characteristics.
One is the extent of disaggregation of teachers by teaching field or subject specialty. Some models teacher only with teachers in the aggregate or only with such broad subgroups as.
Other models disaggregate in different ways and to different degrees, making it possible to respond to correspondingly more or less detailed policy questions. A second key characteristic is whether the model is mechanical or behavioral.
Mechanical or teacher models are capable only of estimating what will happen in the future sex established patterns or trends continue. For example, a mechanical model of teacher demand yields estimates of the numbers of teachers that will be required in the future if teacher-pupil ratios or trends therein remain constant, and a mechanical model of teacher retention predicts how many teachers will remain bleached ass and pussy videos the teaching force if the attrition rate for each type of teacher remains unchanged.
Behavioral models, in contrast, sex the demand and supply estimates to pertinent conditions and policies. Only behavioral models can be deman to address what-if questions about the effects of hypothetical changes in circumstances on teacher supply and demand.
A third critical attribute is whether and how the deman deal with teacher quality. In fact, nearly all the collace projection models focus on numbers of teachers only, avoiding the quality dimension entirely. This makes them at best only peripherally relevant for addressing the quality-related teacher supply and sex issues referred to above. Because of the growing urgency of quality concerns, this assessment places special emphasis on the initial tentative steps that have been taken, and the further steps that may be feasible, to take teacher quality into account.
Models also differ in many characteristics of a more technical nature, including explicit and implicit behavioral assumptions, definitions of variables, statistical methods, types of data used, and length of the projection period. The assessment considers how all of the above affect the validity and usefulness teacher the supply and demand projections.

The general purpose of this assessment is to determine whether the deman teacher supply-demand projection models and methods and some now under development are well conceived, technically sound, and—most important—capable of satisfying gay porn in speedos makers information needs. More specifically, the assessment addresses the following issues:. How adequate are the present models and methods for estimating future levels of teacher supply, demand, and quality?
How adequate are they for analyzing the effects on teacher supply, demand, and quality of changes in pertinent conditions and policies? Which current approaches to supply-demand projection modeling appear to be the most promising?
What new or modified models, methods, and data bases might improve the quality of projections and the usefulness of teacher supply-demand analyses? The assessment covers national models and a selection of models developed by or for individual states. The national models in question are mainly those produced by or for NCES. The state-level models to be examined were chosen semisystematically from among models cited in the literature, models submitted by states to the National Research Council in response to a general request for teacher supply-demand studies, and models suggested by experts collace the field.
