This research examined the role of value orientations in curricular decision making from the perspective of high school physical education teachers and students. Educational value orientations served as the theoretical base for the research. Teachers who exhibited one of two paired orientations, disciplinary mastery/learning process (DM/LP) or ecological integration/social reconstruction (EI/SR), were interviewed to examine the extent to which their value orientations influenced their stated (a) goals for student learning, and (b) expectations for academic performance and behavior. Students were also interviewed to investigate the extent to which they acknowledged these goals and expectations. Data were analyzed using constant comparison. Results suggested that goals and expectations of DM/LP and EI/SR teachers were distinctly different and that comments from students in the EI/SR teachers' classes did not reflect their teachers' goals and expectations. Dynamical system theory was used to conceptualize value orientations as attractors within the educational ecosystem. Teachers working from weak EI/SR value attractors may be limited by learner, instructional, and contextual constraints.  相似文献

Central policymakers are becoming more aware of the possibilities of implementing their policies by using 'softer' discretionary financial instruments in preference to 'harder' directives and conditions attached to granted funds. A typical technique within this softer approach is to offer block grants to any target organization which contracts to pursue specific policy goals and to account for their achievement. Policymakers effectively perceive themselves as 'quasi-consumers', prepared to 'buy' the achievements of their target organizations. Following its new self-perception, the Commonwealth has 'invited' higher education institutions to 'enjoy' the financial benefits of its new Unified National System. Membership is open, however, only to those institutions which undertake to achieve specific organizational reforms desired by the Commonwealth. Moreover block recurrent grants flow to member institutions only after teaching and research targets have been individually negotiated and contracted. An endnote updates the final section on the Relative Funding Model.  相似文献

BackgroundStochastic resonance stimulation (SRS) transmits subsensory electrical Gaussian white noise into the body to enhance sensorimotor function. This therapy has improved static single leg balance in subjects with functional ankle instability. However, the effect of this stimulation on dynamic single leg balance is not known. Improvements in dynamic single leg balance with SRS may have implications for enhancing functional rehabilitation for ankle instability. Thus, the purpose of this study was to determine the effects of SRS on dynamic single leg balance in subjects with functional ankle instability.MethodsThis study was an experimental research design and data were collected in a sports medicine research laboratory. Twelve subjects with functional ankle instability (69 ± 15 kg; 173 ± 10 cm; 21 ± 2 years) reported a history of ankle sprains and instability at the ankle with physical activity. A single leg jump-landing test was used to assess dynamic balance. Subjects were required to jump between 50% and 55% of the maximal vertical jump height, land on a single leg atop a force plate, and stabilize as quickly as possible. Jump-landing tests were performed with and without SRS. Three trials were performed for each treatment condition (SRS and control). A randomized block design was used to determine test order. Anterior/posterior and medial/lateral time-to-stabilization were computed to assess dynamic balance. Lesser time indicated better stability. One-tailed paired samples t tests were used for analysis (α ≤ 0.05).ResultsSRS improved anterior/posterior time-to-stabilization (stochastic resonance = 1.32 ± 0.31 s, control = 1.74 ± 0.80 s, p = 0.03), but did not enhance medial/lateral time-to-stabilization (stochastic resonance = 1.95 ± 0.40 s, control = 1.92 ± 0.48 s, p = 0.07).ConclusionClinicians might use SRS to facilitate balance improvements with sagittal plane dynamic single leg balance exercises that patients may not be able to perform otherwise.  相似文献
