体育专业与非体育专业大学生心肺功能的比较研究

选取32名山西大学体育专业和非体育专业学生为实验对象,采用意大利Cosmed公司生产的心肺功能运动检测系统进行心肺功能各指标的测试和综合评价。结果显示:体育专业男女生安静时心率(HR)明显低于非体育专业男女生(P<0 05)。体育专业学生达到无氧阈(AT)和最大吸氧量( VO2max)时的摄氧量( VO2)、氧脉搏(O2P)、代谢当量(METs)、负荷(LOAD)等指标均高于非体育专业学生(P<0 05)。认为:大学生的心肺功能存在明显的性别差异;体育锻炼可提高人体的心肺功能,获得良好的健康效应。

What Do We Really Know About the edTPA? Research,PACT, and Packaging a Local Teacher Performance Assessment for National Use

This article calls attention to the overreliance on research about the Performance Assessment for California Teachers (PACT)—often labeled edTPA's predecessor—as justification for the edTPA. The article argues that the distinctions between the assessments are too vast to rely on PACT data to support the edTPA, given the localized nature of PACT and the way in which it is scored.

The activities span multiple semesters and are iterative in nature.     

The emergence of the quantified child

Using document analysis, this paper examines the historical emergence of the quantified child, revealing how the collection and use of data has become normalized through legitimizing discourses. First, following in the traditions of Foucault's genealogy and studies examining the sociology of numbers, this paper traces the evolution of data collection in a range of significant education policy documents. Second, a word count analysis was used to further substantiate the claim that data collection and use has been increasingly normalized through legitimizing discourses and routine actions in educational settings. These analyses provide evidence that the need to quantify educational practices has been justified over long periods of time through a variety of documents and that the extent to which data governs educators’ thoughts, discourses, and actions has dramatically increased during the past century.
