Towards collective work and responsibility: Sources of support within a Freedom School teacher community

Alternative and parallel schooling contexts such as the Children's Defense Fund Freedom Schools^® provide educational experiences for U.S. K–12 students grounded in notions of social justice and culturally responsive teaching. College-aged young adults known as “servant-leader interns” are the teachers in this context. In this article, the author examines the nature of the various ways in which servant-leader interns were supported in their development as teachers both at the national training institute and at their local site. This discussion gives explicit attention to the kinds of deliberate support intended by the Freedom Schools program and the kinds of support that the servant-leader interns created or initiated on their own. Implications for teacher support that occur in alternative and parallel schooling contexts are discussed.     

‘Dangerous presumptions’: how single‐sex schooling reifies false notions of sex,gender, and sexuality

Due to the recent changes in federal regulations about gender equity in education in the USA, some policy makers have resurrected single‐sex public education. Because single‐sex schooling ignores the complexity of sex, gender, and sexuality, it sets up a ‘separate but equal’ system that is anything but. Discounting the ways in which gender is negotiated, constructed, and performed, and the variability of anatomical sex, current arguments for single‐sex schooling reify the false binaries of sex and gender, rely on assumptions of heteronormativity and, in turn, negate the existence of multiple sexes, genders, and sexual orientations.     

An Analysis of the Validity of the Three-Mile Run as a Field Test of Aerobic Capacity in College Males

Abstract

The purpose of the present investigation was to examine the concurrent and construct validity of the three-mile (4.83 km) run as afield test of aerobic capacity. Subjects included 109 college-aged males whose three-mile run time (M = 1310.31 ± 184.48 s) was measured. Fifty of the subjects were given a maximal treadmill stress test, and their peak oxygen consumption (VO₂peak) (M = 54.23 ± 7.08 ml.kg^?1.min^?1) was measured. The three-mile run was conducted on an outdoor 0.25 mile (0.425 km) track, and split tunes were recorded each 110 yds (100.32 m) for the first and last laps and total time was recorded for laps 2 through 11. The correlation coefficient between the run time and VO₂peak was -.58, indicating only moderate concurrent validity for the run as afield test for aerobic capacity. A factor analysis conducted on the split time data revealed a three-factor structure of a stable pace phase, an initial sprint, and a final sprint with the stable pace factor accounting for most of the common factor variance (69%). The three-mile run time was used to discriminate successfully between two known groups of subjects in aerobic capacity. These data provide a degree of support for the construct validity of the three-mile run as afield test of aerobic capacity.     

Active Transportation to School

Abstract

Cinematographical analysis was used to compare spatial and temporal relationships of ten skilled and ten non-skilled performances of the standing broad jump. Means of the extent and duration of major joint action for the two levels of skill were represented graphically. Characteristic likenesses appeared in the general patterns of movement of limbs and in proportion of time consumed by the phases of the movement. Characteristic differences were found in angles of take-off and of landing and in extent and duration of specific joint actions. Greater extent of movement occurred in the skilled performances. The latter characteristically used more time in hip flexion and less time in knee extension.     

Age,Physical Activity,Physical Fitness,Body Composition,and Incidence of Orthopedic Problems

Abstract

The incidence of orthopedic problems was examined in 5, 582 men and women who attended the Cooper Clinic in Dallas, Texas between 1974 and 1982. The effects of age, physical activity, physical fitness, and body mass index (EMI) on the occurrence of these problems were examined using a proportional hazards approach. The expected risk of orthopedic problems per person-year was 0.045 for men and 0.046 for women. For men, physical fitness, BMI, and physical activity were associated with orthopedic problems, while for women, physical activity was the main predictor. Age was not a factor for either gender. The effect of change in physical fitness, physical activity, and BMI was examined in a subset of 2, 325 persons with more than one visit to the clinic. For women, physical activity and a decrease in BMI were associated with orthopedic problems, while for men none of those factors were significant. Again, age was not a factor in either group. The absence of any age effect on the occurrence of problems suggests that with regard to orthopedic problems, moderate amounts of physical activity in generally healthy persons may be recommended without special consideration as to age.
