Weight factor selection in double exponential smoothing enrollment forecasts

The merits of double exponential smoothing are discussed relative to other types of pattern-based enrollment forecasting methods. The basic assumptions and formulas for its use are outlined. The difficulties associated with selecting an appropriate weight factor are discussed, and the potential effect on prediction results is illustrated. Two methods for objectively selecting the best weight factor are described and analyzed, and evidence is presented suggesting that they may be used effectively in the enrollment-forecasting process.Presented at the Twentieth Annual Forum of the Association for Institutional Research, Atlanta, April 1980.     

Our Constructed Reality: Some Contributions of an Alternative Perspective to Physical Education Pedagogy

This paper describes a loose coalition of ideas that form an alternative perspective to the dominant research and development work currently being conducted in physical education pedagogy. It is argued that the profession will be best served if both perspectives better understand and share their assumptions, and especially if they recognize the subjective nature of their work.
