Short-to-Medium Term Enrollment Projection Based on Cycle Regression Analysis

Description: Short-to-medium projections were made of student semester credit hour enrollments for North Texas State University and the Texas Public and Senior Colleges and Universities (as defined by the Coordinating Board, Texas College and University System). Undergraduate, Graduate, Doctorate, Total, Education, Liberal Arts, and Business enrollments were projected. Fall + Spring, Fall, Summer I + Summer II, Summer I were time periods for which projections were made. A new regression analysis called "cycle regression" which employs nonlinear regression techniques to extract multifrequential phenomena from time-series data was employed for the analysis of the enrollment data. The heuristic steps employed in cycle regression analysis are similar to those used in fitting polynomial models. A trend line and one or more sin waves (cycles) are simultaneously estimated using a partial F test. The process of adding cycle(s) to the model continues until no more significant terms can be estimated.

A State-Wide Survey on the Utilization of Instructional Technology by Public School Districts in Texas

Description: Effective utilization of instructional technology can provide a valuable method for the delivery of a school program, and enable a teacher to individualize according to student needs. Implementation of such a program is costly and requires careful planning and adequate staff development for school personnel. This study examined the degree of commitment by Texas school districts to the use of the latest technologies in their efforts to revolutionize education. Quantitative data were collected by using a survey that included five informational areas: (1) school district background, (2) funding for budget, (3) staff, (4) technology hardware, and (5) staff development. The study included 137 school districts representing the 5 University Interscholastic League (UIL) classifications (A through AAAAA). The survey was mailed to the school superintendents requesting that the persons most familiar with instructional technology be responsible for completing the questionnaires. Analysis of data examined the relationship between UIL classification and the amount of money expended on instructional technology. Correlation coefficients were determined between teachers receiving training in the use of technology and total personnel assigned to technology positions. Coefficients were calculated between a district providing a plan fortechnology and employment of a coordinator for instructional technology. Significance was established at the .05 level. A significant relationship was determined between the total district budget and the amount of money allocated to instructional technology. There was a significant relationship between the number of teachers receiving training in technology and the number of personnel assigned to technology positions. A significant negative relationship was determined between the district having a long-range plan for technology and the employment of a full-time coordinator for one of the subgroups. An attempt was made to provide information concerning the effort by local school districts to provide technology for instructional purposes. Progress has been made, although additional funds will be ...
