Waist Circumference,Pedometer Placement,and Step-Counting Accuracy in Youth

This study examined whether differences in waist circumference (WC) and pedometer placement (anterior vs. midaxillary vs. posterior) affect the agreement between pedometer and observed steps during treadmill and self-paced walking. Participants included 19 pairs of youth (9–15 years old) who were matched for sex, race, and height and stratified by WC (high WC: HWC; low WC: LWC). Participants performed 3-min treadmill-walking trials at speeds of 59, 72, and 86 m·min-1 and a 400-m self-paced walking trial on level ground. Bland-Altman plots were used to assess the agreement between pedometer and observed steps of spring-levered pedometers by WC, pedometer placement, and walking speed. In the HWC group, the posterior pedometer placement consistently agreed most closely with observed steps at all treadmill speeds and during self-paced walking. In the LWC group, no single pedometer placement consistently agreed most closely with observed steps at all treadmill speeds and during self-paced walking. We conclude that a posterior pedometer placement improves step-count accuracy in most youth with an HWC at a range of walking speeds on level ground.     

Adults who learn differently: Help through a volunteer literacy program

In adult literacy programs today, well-intentioned but inadequately prepared volunteer tutors are being matched with learning disabled adult students without the benefit of receiving training from experts in the field of language/learning disabilities. The collaboration of adult literacy providers and learning specialists is obviously the most resourceful, yet most untried, solution to a problem that is plaguing volunteer-based programs across the country: meeting the needs of learning disabled adults. One adult literacy program—READ/San Diego of the San Diego Public Library—recognized that its volunteer tutors needed training in special instructional methods to teach adults who evidence learning disabilities. Accordingly, the program’s administrator obtained the services of specialists to develop a learning disabilities tutor-training module. This article (1) presents an overview of preservice volunteer training at READ/San Diego; (2) discusses informal assessment procedures that help identify possible language/learning disabilities in adults and provide valuable information for instructional planning; and (3) describes selected multisensory teaching techniques designed especially for adults who “learn differently.”
