Standards‐based progress reports (SBPRs) require teachers to grade students using the performance levels reported by state tests and are an increasingly popular report card format. They may help to increase teacher familiarity with state standards, encourage teachers to exclude nonacademic factors from grades, and/or improve communication with parents. The current study examines the SBPR grade–state test score correspondence observed across 2 years in 125 third and fifth grade classrooms located in one school district to examine the degree of consistency between grades and state test results. It also examines the grading practices of a subset of 37 teachers to determine whether there is an association between teacher appraisal style and convergence rates. A moderate degree of grade–test score convergence was observed using three agreement estimates (coefficient kappa, tau‐b correlations, and classroom‐level mean differences between grades and test scores). In addition, only small amounts of grade–test score convergence were observed between teachers; a much greater proportion of variance lay within classrooms and subjects. Appraisal style correlated weakly with convergence rates, but was most strongly related to assigning students to the same performance level as the test. Therefore using recommended grading practices may improve the quality of SBPR grades to some extent. 相似文献

In this article we first try to answer the question posed in the title in the context of a real life situation. We suggest
sequential methods of selecting a member from a given set of individuals. We show that these methods indeed assign ‘equal
chance’ of being selected to all individuals. 相似文献

Environmental education usually appeals to the students’ knowledge and rational understanding. Even though this is needed, there is a neglected aspect of learning ecologically fruitful action; that of the lived‐body. This paper introduces the lived‐body as an important site for learning ecological action. An argument is made for the need of a biophilia revolution, in which refined experience of the body and enhanced capabilities for sensing are seen as important ways of complementing the more common, knowledge‐based environmental education. Alienation from the physical environment is seen as one key element in producing environmental devastation. Consequently, human alienation from nature is seen as closely related to alienation from one's body. It is claimed that through overcoming the (Cartesian) dualist alienation of human consciousness from its lived body, we can decrease the alienation of human beings from their environment. Methods of contemplative pedagogy are introduced for addressing alienation. By getting in touch with the tangible lived‐body in yoga or mindfulness meditation we reconnect to the material world of nature. Contemplative pedagogy cultivates the body and its senses for learning intrinsic valuation and caring for the environment. Lived‐body experience is challenging to conceptualise; we use Maurice Merleau‐Ponty's concept of the flesh in our attempt to do so. Finally, this paper suggests some contemplative practices of the lived‐body for environmental education. Experiencing the flesh of oneself and the world as one and the same is an environmentally conducive experience that gives value and meaning to the flourishing of all life, human and non‐human. 相似文献

The pilot issue of the data collection of the All-Russian Institute of Scientific and Technical Information of the Russian Academy of Sciences “Industry of Nanosystems and Nanomaterials” gives an approximate view of the state of this field of science at the beginning of 2007. The topics of articles in the pilot issue are analyzed. The directions of development of nanotechnologies are shown. The basic types of nanomaterials, the methods of their production, and their properties and applications are given. 相似文献

In this paper, the consideration of the problem of the competitiveness of scientific research as an independent scientific line in the context of the science of science, whose main methodological instruments could be the adapted economic concepts of competitiveness and clusters, as well as mathematical models of competitive interactions (including models described in the terms and equations of population dynamics) and the methods of scientometric analysis, is proposed. It is shown that solution of the problem of increasing the competitiveness of post-Soviet scientific research falls within the domains of information communication. In addition, the role of the international movement for public access to scientific knowledge in increasing the competitiveness of scientific research is considered. 相似文献

Five women and 5 men were studied to examine the effects of submaximal exercise on thermoregulatory and hemodynamic variables during recovery in two environments: (a) control (C), 22 degrees C, 33% rh; and (b) hot humid (H), 32 degrees C. The participants exercised on a cycle ergometer at 60% of peak oxygen consumption for 35 min prior to 90 min of seated recovery. Sessions were identical, except for environment. Variables evaluated (p < .05) were: core temperature (TR), mean skin temperature (Ts), sweat rate (SR), heart rate (HR), stroke index (SI), cardiac index (CI), forearm blood flow (FBF), systolic blood pressure (SBP), and diastolic blood pressure (DBP). Men and women exhibited similar patterns of TR, Ts, and SR in both environments. Ts and SR (collapsed means for gender) were higher in the H than in the C. DBP was higher in men than in women throughout recovery in both environments. With combined means for gender, HR was higher in the H than in the C. CI, SI, FBF, and SBP were similar in both environments and returned to baseline within 15 min into recovery. These data suggest that heat dissipation during extended recovery was accomplished with similar contributions of cutaneous vasodilation and sweating in M and F. Furthermore, the moderate exercise level did not influence hemodynamics beyond 15 min of recovery in either environment. 相似文献
