This investigation sought to validate a taxonomy of strategies used in formulating the feedback supplied to teacher trainees involved in the peer teaching segment of a secondary methods class. Lesson deficiencies were diagnosed through analysis of student and teacher process behavior data. Certain student and teacher response classes were selected for each trainee as dependent variables (DVs) and targeted for improvement. Goals were set for each DV and strategies for improvement were suggested by teacher educators (TEs). These strategies, selected from a taxonomy developed in previous work (Hawkins, Wiegand, & Landin, 1985), served as independent variables (IVs). A modified changing criterion design was employed to evaluate the data. Strategy effectiveness was determined by analyzing the degree to which trainees met data-based goals for the targeted response classes. Results indicated that several strategies seemed useful for a wide variety of activities. Also indicated by the results is the need for teacher trainers to be better prepared to handle large classes.

, the investigators never validated the equation. Furthermore, their sample was small and homogenous, consisting of just 50 Korean high school athletes (mean ±  SD ; age = 16.6 ± 1.0 years, height = 171.6 ± 8.3 cm, weight = 63.3 ± 7.9 kg, body fat percentage = 9.6 ± 3.5%). These sample characteristics

-specific BSIPs, however, a key problem is that no female-specific geometric models for estimating BSIPs have been validated, despite significant differences in the shapes of segments between males and females. 3 There are several methods of estimating BSIPs. Scanning techniques such as dual x-ray absorptiometry

treatment monitoring in sport psychological practice; therefore, the current study sought to create an instrument addressing this need. This research endeavor resulted in the development and initial psychometric validation of a 17-item self-report instrument that measures four dimensions of progress

. Our goal was to evaluate the TUG test as an indicator of balance. To assess the TUG test, we selected the OptoGait gait test as a tool with which we could compare TUG performance. The OptoGait photoelectric system has been validated as an effective tool for precise measurement of spatiotemporal gait

We propose that physiological and performance tests used in sport science research and professional practice should be developed following a rigorous validation process, as is done in other scientific fields, such as clinimetrics, an area of research that focuses on the quality of clinical measurement and uses methods derived from psychometrics. In this commentary, we briefly review some of the attributes that must be explored when validating a test: the conceptual model, validity, reliability, and responsiveness. Examples from the sport science literature are provided.

The measurement of physical activity patterns has the potential to reveal underlying causes of changes in modifiable risk-factors associated with health and well-being. Accurate classification of physical activity (PA) in free-living situations requires the use of a validated measurement system to
