尴尬的教育学和教育学的尴尬

导致教育学尴尬的原因在于教育学自身的不足,主要表现为理论研究脱离实际和基本概念尚未廓清这两方面.摆脱尴尬局面,也主要从这两方面入手.

Impact of a pedometer-based goal-setting intervention on children’s motivation,motor competence,and physical activity in physical education

Background: School physical education (PE) programs provide a prime environment for interventions that attempt to develop school-aged children’s motor competence and overall physical fitness, while also stimulating competence motivation to engage in physical activity during childhood. It is generally recognized that a pedometer-based intervention strategy combined with a goal-setting strategy may be effective in increasing physical activity participation among school-aged children. The purpose of this study was to evaluate the impact of an 8-week pedometer-based goal-setting intervention on children’s motivation in PE, motor competence, and physical activity.

Methods: A pretest–posttest comparison group design was used with the 8-week intervention (3 days/week for 24 sessions). Participants were 273 (boys?=?136, girls?=?137) students recruited from 3 elementary schools in the US. Classes in each school were randomly allocated to three experimental conditions: (1) an intervention group with a personalized pedometer weekly target to reach in their PE class (N?=?110), (2) an intervention group with the fixed pedometer target range to reach in each PE class based on the recommended criteria (N?=?90), or (3) a control group without intervention (N?=?73).

Analysis/results: The factorial repeated measures MANOVA indicated significant multivariate effects for the group [F(6, 528)?=?12.954, p?Post hoc analyzes showed that both experimental groups had significantly higher expectancy-value beliefs, motor competence, and physical activity compared to the control group (p?Conclusions: Health practitioners should be aware that goal-directed action can contribute to school students’ PE-related achievement motivation, motor competence, and achieving the recommended 60?min of moderate-to-vigorous physical activity.     

核态沸腾中汽化核心密度的分形分布

本文首先回顾了在核态沸腾传热中影响汽化核心密度分布的几个关键因素,然后运用分形理论讨论了加热壁面微结构和汽化核心密度之间的关系并分析了两个核态沸腾实验中汽化核心密度的数据。一个实验是考察加热壁面在老化过程中汽化核心密度的变化,另一个实验是考察两个不同材料制成的加热壁面上汽化核心密度的差异。实验数据分析结果表明汽化核心密度与最小成核半径之间呈分形关系。不同加热壁面对应不同的分形维数,分形维数是一个定量描述加热壁面状况的参数。     

从废旧锂离子电池中回收制备LiAlO2材料

采用高温固相法，自废旧锂离子电池中回收制备LiAlO2，并采用XRD方法表征了LiAlO2的物相成份。结果表明，900℃培烧2h制备的LiCoO2与Al箔按化学计量比n（Li）：n（A1）=4：5混合均匀后，再在800℃培烧2h后制备的LiAlO2的晶形结构较好。     

简评苏联“照会攻势”

1952年春夏,苏联为阻止西方集体安全体系的建立和西德重新武装,在五个多月内与美英法三国交换了八次照会,史称苏联“照会攻势”。本文通过对冷战中这一著名外交事件的介绍和评论,展示了东西方国家在战后处理德国统一和欧洲安全问题上的具体行动,揭示了苏联在贯彻“以统一换中立”对德战略时在具体外交政策上的得与失。     

核物理电化学刻蚀分析中智能化高压电源的研制

提出了一种用于电化学刻蚀(ECE)分析的可编程高压电源实现方案.利用MAX038作为波形发生器,采用P89LPC936 MCU进行控制.电源的输出频率可达2 kHz,电压峰一峰值可达8 000 V.由于系统采用了MCU控制,提高了电源的输出频率和电压的精度,增强了电源的可靠性,并具有工作数据的记录功能.     

创业教育的研究

创业教育是提高学生创业基本素质，培养创业意识。形成创业生存能力的教育。开展创业教育是高职院校顺应时代潮流，服务社会的必然选择。创业教育是一项涉及全社会的系统工程，需要政府、学校、企业等方面共同实施。从学校来讲，要改革培养模式，全方位渗透创业教育。要改进就业指导工作服务体系，营造良好的创业教育环境。
