A New Way to Teach (or Compute) Pearson's r Without Reliance on Cross‐Products

Many students have difficulty seeing the conceptual ‘link’ between bivariate data displayed in a scatterplot and the statistical summary of the relationship, r. This article shows how to teach (and compute) r such that each datum's ‘direct’ and ‘indirect’ influences are made apparent and used in a new formula for calculating Pearson's r.     

I am not a jinetero

Phantomism is a juvenile social pathology that destroys the social standards set by the Revolution. Its catalyst was the severe endogenous economic crisis brought about by the international socialist plan. That plan created a dangerous socioideological tension in Cuba, which began a socioeconomic restructuring at that time, aimed at creating continuity for the socialist plan. Phantomism is expressed as a retrograde alternative and is reinforced by an alienated individualism that emphasizes consumerism. It is linked to a bourgeois ideology, which is contrary to the humanism of Cuban socialism.     

“固然”的多角度分析及教学探讨

＂固然＂常和＂但是＂连用,它的使用有特殊的语义背景,＂固然＂所在的小句承认对方刚刚提出的事实或很多人公认的看法,＂但是＂所在的小句表达反转的语义,是说话人表达的重心。＂固然……但是＂句有4种主要格式：A固然C,但是（A）也D（C和D有相反的关系）;A固然C1,但是B也C2。（C1、C2有类同的关系）;A固然C1,但是（如果/只要）……,A就不C2了。（C1、C2有类同的关系）;A固然C1,但是更C2的是……（C1、C2有类同的关系）。＂固然＂的使用受到语体、篇章和预设的影响,在对外汉语教学实践中营造论辩会话语境进行＂固然＂主要格式的操练能收到很好的效果。     

The Project ‘Art for Learning Art’ in Contemporary Art Museums

Projection‐based augmented reality and virtual reality are used in a visual arts‐based educational project in contemporary art museums from an a/r/tographic perspective. The project ‘Art for Learning Art’ (in Spanish, Arte para aprender arte), at the Museo CajaGRANADA in Granada (Spain) has been developed in collaboration with the University of Granada since 2013. We have employed creative, educational and research methodologies inspired by exhibited works in art museums to encourage visual feedback of visitors participating in collaborative installations. Two such experiences also were produced at the Tate Liverpool Gallery and Museum in March 2018; utilising the methodology of mediation through projection‐based augmented reality and virtual reality, which introduces facets of visual and physical experience that alter the whole experience for the museum's public. By putting on virtual reality headsets, and playing with physical movements, we generate images and change the projections in the museum using projection‐based augmented reality to disrupt the way the public typically moves in the museum. The purpose of the developed interrelations with artworks in the Museo CajaGRANADA and the Tate Liverpool Gallery and Museum was to create collaborative digital images by playing with select artworks exhibited in the museums’ collections. We use this kind of mediation in art museums to develop a visual understanding to provoke learning about art through art creation in a contemporary way. The results are extraordinary as images; they are collaborative artworks, which connect visually with the artworks in the exhibition.

谈理想实验在物理发展中的作用

理想实验是一种重要的科学研究方法。研究理想实验在物理学发展中的作用,既有利于认识、理解和掌握理想实验,并将其自觉地运用在对物理学的研究中,导出一些科学的结论;又有利于在物理教学中很好地把理想实验方法传给学生,培养学生逻辑推理能力和抽象思维方法。

细沟侵蚀可蚀性参数及土壤临界抗剪应力的有理(实验)求解方法

利用室内细沟侵蚀模拟试验结果,把细沟可蚀性参数和土壤临界抗剪应力的研究与侵蚀的过程结合起来,通过对土壤水蚀预报模型WEEP中控制土壤侵蚀的水动力学模型进行理论分析,导出了由实验直接计算得到细沟侵蚀可蚀性参数Kr 值及土壤临界抗剪切应力τc的方法.由推导得到的计算方法与计算公式,求得了不同工况下细沟侵蚀可蚀性参数及相应的临界抗剪切应力值.结果表明,对于同一种土壤,在不同的水动力学条件下,计算得到的细沟侵蚀可蚀性参数基本是一致的.对于实验所用的黄绵土,计算得到的细沟可蚀性参数Kr 均值为( 0 32 4± 0 0 0 3)kg·N-1·s-1.临界抗剪切应力τc 随坡度的增大有增大的趋势.不同水动力条件下回归系数值均大于 0 71.提出的计算细沟侵蚀可蚀性参数Kr 值及土壤临界抗剪切应力τc的方法,将有助于建立和完善土壤侵蚀预报过程模型.
