跨界融合视域下劳动教育课程体系研究——内涵、路径与模型构建

针对当前劳动教育地位缺失的问题,剖析了其主要原因在于社会意识缺失、过分依赖学校及课程设置不规范。因此,该文基于新的时代背景,从劳动形态、教育内容和价值三个方面对劳动教育的内涵进行了剖析,提出技术赋能的劳动教育课程体系:在横向上实现各学科知识的融合,纵向上实现各学段的融合,为解决劳动教育现存问题提供了新方向。同时,从技术创新劳动教育形态和整合劳动教育资源两个方面阐述了劳动教育跨界融合的途径。最后,依据跨界融合的课程体系,从前端分析、活动设计、环境设计和评价设计四个方面构建了劳动教育活动模型,为技术赋能的劳动教育课程的实施提供依据。     

各向异性完全匹配层边界条件下雷达散射截面的误差修正

为了提高时域有限差分法的计算精度,以二维金属圆柱散射为例,研究了在各向异性完全匹配层(UPML)吸收条件下,改变总场-散射场的输出及吸收边界时误差的变化规律。比较了UPML与二阶Mur吸收边界条件下的误差。同时发现,可采用迭代步数相差半个周期的双站雷达散射截面(RCS)的平均来减小误差,也可采用距离为半个波长的两个输出边界得到RCS的平均来减小误差。

人天整体观的主要内涵

人与天地万物都是由元气，元光，元音组成；都遵循着生化返的极化规律，处在运动，发展，变化之中；人的身心变化，与大自然的阴阳消长息息相关，人与天地万物应当相亲和相和。     

The relationship between cellphone use and achievement goals in junior high school students: A cross‐lagged analysis

The purpose of this study was to explore the relationship between cellphone use and achievement goals in junior high school students. The participants were 282 students randomly selected from a secondary school in Xi'an, China. The Frequency of Cellphone Use Questionnaire and the Achievement Goal Questionnaire were used as measurement tools. The results showed that cellphone use at Time 1 (T1) was significantly associated with performance goals orientation and with mastery goals orientation at both times; cellphone use at Time 2 (T2) was not correlated with performance goals orientation or mastery goals orientation at T1. The cross‐lagged analysis showed a negative causal relationship between the frequency of cellphone use and mastery goals but no causal relationship between the frequency of cellphone use and performance goals. These results may be helpful for guiding adolescents to reduce cellphone use, pay attention to the mastery of knowledge, and establish mastery goals.     

The development and validation of a scale measuring teacher autonomous behaviour

In the current study a multi‐dimensional scale that measures teacher autonomous behaviour is presented. The scale is applicable across the following educational sectors: primary education, secondary education and vocational education. Based on an elaborate literature study, four theoretically relevant dimensions of teacher autonomous behaviour were derived. Psychometric characteristics of the instrument (note that the terms ‘scale’ and ‘instrument’ are used interchangeably in this article) were tested among a sample of Dutch teachers working in primary, secondary and vocational education (N = 1111). The validity of our instrument was tested in several ways. First, by performing confirmatory factor analysis, we tested the factorial structure, which confirmed the hypothesised four dimensions: (1) primary work processes in the class; (2) curriculum implementation; (3) participation in decision making at school; (4) professional development. Thereafter, we calculated the scale's reliability, which appeared to be excellent. In addition, we tested for measurement invariance by cross‐validating the study in the educational sectors mentioned above. Also, the convergent, divergent and predictive validity was investigated. Teacher autonomy appeared to predict workplace learning, more specifically experimenting, reflecting and school development. Finally, we investigated whether transformational leadership can facilitate teacher autonomy, which appeared to be the case. The results empirically confirm the four dimensions of teacher autonomous behaviour, which we derived from theory, and offer solid proof of the psychometric properties of our instrument. The instrument can be used by school leaders and policy makers to monitor autonomous behaviour. More generally, the development and use of this instrument helps us understand teacher autonomous behaviour and teacher professionalism.     

电子与奇异丰质子核弹性散射的微分截面和电荷形状因子

用相对论分波展开法研究了电子与12,16O和28,32S弹性散射的微分截面以及12,16O和28,32S的电荷形状因子,其中核的电荷密度分布利用自洽相对论平均场模型来计算。数值结果与已有的实验数据进行了比较,结果表明目前的理论是可靠的,计算显示12O和28S的扩展的电荷分布对于电子-核散射的微分截面以及电荷形状因子具有可观测的效应。
