A basic and affordable experimental apparatus is described that measures the static contact angle of a liquid drop in contact with a solid. The image of the drop is made with a simple digital camera by taking a picture that is magnified by an optical lens. The profile of the drop is then processed with ImageJ free software. The ImageJ contact…

Designing and implementing assessment instruments are ongoing challenges for physical educators. The initial design phase includes asking the question, "What do I want the students to know and/or be able to do?" Seemingly, the question is direct and should lead to a concrete answer. In addition to designing assessment instruments, one of the most…

Rupture resistance is a measure of the strength of a soil to withstand an applied stress or resist deformation. In soil survey, during routine soil descriptions, rupture resistance is described for each horizon or layer in the soil profile. The lower portion of the rupture resistance classes are assigned based on rupture between thumb and…

The use of heart rate measurement to aid in the design of individualized exercise programs is suggested. (LH)

From a study on drug treatment effects on the memory and affective functioning of ambulatory geriatric volunteers, the author recommends several methodological accommodations as necessary and expedient to geriatric assessment. Special procedural attention is required by certain characteristics unique to, or exaggerated among, elderly participants.…

Health education researchers have occasionally used measuring tools inappropriately. Test validity and the use of criterion-referenced tests are discussed in view of this need to improve health education research. Also described are handbooks containing measuring devices for the use of health education researchers. (CJ)

Staff development programs and evaluation designs can be improved by applying four principles: (1) Range of evaluation criteria should match range of outcomes; (2) Program outcomes should be concrete and specific to assist in formulation of evaluation criteria; (3) Evaluation design rigor should reflect the program's power; and (4) Evaluation…

Six areas of staff development program evaluation in which participants may be meaningfully involved are: (1) clarification of the program's goals; (2) development of a design for the evaluation study; (3) development of methods for measurement; (4) analysis of information; (5) response to evaluation instruments; and (6) reporting on an evaluation…

We present an overview of the methodology employed in the Parents Matter! Program. Information on the following aspects of the program is presented: participant eligibility and recruitment; consenting procedures and administration of assessments; development and utilization of measures in the assessments; study design; intervention procedures;…
