Elementary School Personnel and Cultural Factors Affecting Health Education Implementation in the High-Stakes Testing Era.

BACKGROUND: Despite proven health and learning benefits, health education implementation in elementary schools is not optimal. This study investigated learning environment, leadership, and training factors that may influence elementary-level health education implementation in the current standardized testing-saturated environment. METHODS: Survey data were collected from principals of 8 Michigan elementary schools and, via focus groups, 30 teachers in their schools. Teacher groups were separated into 2 categories based on principals' understanding of state health education policies. Grounded theory analysis was used. RESULTS: Despite all 30 teachers' positive attitudes toward health education, numerous consistent implementation barriers were identified; competition for instructional time with tested subjects was most critical. Teachers with principals who indicated a greater understanding of state policies reported more: consistent instruction; availability of resources, and encouragement to teach select topics, especially mental health. CONCLUSION: That these findings were produced in a state with strong CSHE polices, proven curricula, and expansive support systems are disheartening and accentuate the profound impact of standardized testing on elementary-level health education implementation. More promising, principals' understanding of applicable state-level policies appeared to generate stronger health education implementation. Future research should focus on the possible impact of time devoted to health instruction on standardized test scores.

Mold spore penetration through wall service outlets: a pilot study.

A pilot study was conducted to estimate fungal spore penetration for wall service outlets subjected to a constant air pressure. During the laboratory experiment, a wall chamber was fabricated, and telephone, electrical, and cable service outlets were installed. Penicillium chrysogenum spores were aerosolized into the chamber that was held under pressure. Spores that penetrated the outlets were funneled into an impinger for microscopic enumeration. Thirty trials were conducted for each of the five outlets (N = 150), and the wall chamber was decontaminated between trials. Results of an analysis of variance suggest wall service outlets allow spore penetration. The penetration factor for the telephone outlet was significantly greater than all other outlets (p < 0.05), and there was no difference in penetration between electrical outlets with and without plugs. Penetration factor differences were attributed to air leakage rates across the outlets. Due to the experimental design and equipment limitations, further research is needed to support these findings.

Eccentric plantar-flexor torque deficits in participants with functional ankle instability.

CONTEXT: Inversion ankle sprains can lead to a chronic condition called functional ankle instability (FAI). Limited research has been reported regarding isokinetic measures for the plantar flexors and dorsiflexors of the ankle. OBJECTIVE: To examine the isokinetic eccentric torque measures of the ankle musculature in participants with stable ankles and participants with functionally unstable ankles during inversion, eversion, plantar flexion, and dorsiflexion. DESIGN: Case-control study. SETTING: Athletic training research laboratory. PATIENTS OR OTHER PARTICIPANTS: Twenty participants with a history of "giving way" were included in the FAI group. Inclusion criteria for the FAI group included a history of at least 1 ankle sprain and repeated episodes of giving way. Twenty participants with no prior history of ankle injury were included in the control group. INTERVENTION(S): Isokinetic eccentric torque was assessed in each participant. MAIN OUTCOME MEASURE(S): Isokinetic eccentric testing was conducted for inversion-eversion and plantar-flexion-dorsiflexion movements. Peak torque values were standardized to each participant's body weight. The average of the 3 trials for each direction was used for statistical analysis. RESULTS: A significant side-by-group interaction was noted for eccentric plantar flexion torque (P < .01). Follow-up t tests revealed a significant difference between the FAI limb in the FAI group and the matched limb in the control group. Additionally, a significant difference was seen between the sides of the control group (P = .03). No significant interactions were identified for eccentric inversion, eversion, or dorsiflexion torques (P > .05). CONCLUSIONS: A deficit in plantar flexion torque was identified in the functionally unstable ankles. No deficits were identified for inversion, eversion, or dorsiflexion torque. Therefore, eccentric plantar flexion strength may be an important contributing factor to functional ankle instability.
