谁来评价高中综合素质?——基于利益相关者的分析

从利益相关者的视角来看,综合素质评价结果一旦与学生、教师和高中学校的利益高度相关,那么由这些利益高度相关的主体来进行评价时,由于受到"理性经济人"自利性的制约,利益高相关主体极有可能因自身利益的最大化并最终导致评价结果的失真。评价结果的客观性取决于"评价什么",更取决于"谁来评价",甚至可以说,"谁来评价"会直接影响着"评价什么"。而就综合素质评价的实施来看,学生更多的是综合素质评价材料的记录主体,高中学校(包括行政管理人员和教师等)更多的是综合素质评价材料真实性的监督主体,而高校才是最终、最佳的综合素质评价主体。     

Evaluation of Internet Information Sources by High School Students in Ghana

The Internet clearly presents the opportunity for students to expand their knowledge at a fast pace, since they are able to access enormous amount of information. However, accessing the Internet also has its downside since not all information is of good quality. The study explored how 12th grade students at a high school in Ghana evaluated online information sources. These students and the head of the Information Communication Technology department respond to self-administered questionnaires and a semi-structured interview, respectively. The study found that most of the high school students did some kind of an evaluation of online information sources, however, they were not applying the right criteria. The study further revealed that students were not introduced to evaluation criteria at school and this had contributed to the gap in their evaluation competencies.

大学生运动锻炼组与非运动锻炼组若干生活方式要素的分析与比较

运用Prentice,W.E.于1990建立的健康生活方式自评量表(来自Fitness and Wellnessfor Life),对江苏省10所高校大学生的生活方式进行实证调查。选取该量表中的“运动锻炼”指标对大学生进行分类,比较“锻炼组”和“非锻炼组”大学生其他生活方式要素的异同。结果表明:“锻炼组”和“非锻炼组”大学生在“吸烟”、“遵医嘱服药”、“每日食物多样性”、“学习的积极性”、“寻求感情释放和帮助”、“参加集体活动”等生活方式要素方面均存在差异,说明锻炼与否与健康生活方式的形成存在较高的相关性。     

The effect of acute aerobic exercise on central arterial stiffness,wave reflections,and hemodynamics in adults with diabetes: A randomized cross-over design

BackgroundIndividuals with diabetes have greater central arterial stiffness, wave reflections, and hemodynamics, all of which promote the accelerated cardiovascular pathology seen in this population. Acute aerobic exercise has been shown to be an effective strategy for reducing central arterial stiffness, wave reflections, and hemodynamics in healthy individuals; however, the effects of acute aerobic exercise in reducing these outcomes is not well established in people with diabetes. Recently, implementation of high-intensity interval exercise (HIIE) has shown superior improvements in cardiovascular health outcomes when compared to traditional aerobic exercise. Yet, the effect of HIIE on the aforementioned outcomes in people with diabetes is not known. The purpose of this study was to (i) describe the central arterial stiffness, wave reflections, and hemodynamic responses to a bout of HIIE and moderate-intensity continuous exercise (MICE) in adults with diabetes; and (ii) compare the effects of HIIE and MICE on the aforementioned outcomes.MethodsA total of 24 adult men and women (aged 29–59 years old) with type 1 (n = 12) and type 2 (n = 12) diabetes participated in a randomized cross-over study. All participants completed the following protocols: (i) HIIE: cycling for 4 × 4 min at 85%–95% of heart rate peak (HR_peak), interspersed with 3 min of active recovery at 60%–70%HR_peak; (ii) MICE: 33 min of continuous cycling at 60%–70%HR_peak; and (iii) control (CON): lying quietly in a supine position for 30 min.ResultsA significant group × time effect was found for changes in central systolic blood pressure (F = 3.20, p = 0.01) with a transient reduction for the HIIE group but not for the MICE or CON groups. There was a significant group × time effect for changes in augmentation index at a heart rate of 75 beats/min (F = 2.32, p = 0.04) with a decrease following for HIIE and MICE but not for CON. For all other measures of central arterial stiffness and hemodynamics, no significant changes were observed (p > 0.05).ConclusionA bout of HIIE appears to lead to a greater transient reduction in central systolic blood pressure than the reduction observed following MICE; however, both HIIE and MICE improved augmentation index at a heart rate of 75 beats/min in people with diabetes. There was no significant difference in response to HIIE and MICE in all outcomes. This provides preliminary evidence on the role of HIIE on such outcomes in people with diabetes.
