核心素养视域下的“三一三” 物理生长课堂

针对新授课、习题课、复习课等,课堂教学结构应有所区别.在“三动课堂”的研究基础上,通过实践探索,优化教学结构,发现“三一三”课堂模型对新授课有特别的优势.它采用“情境探究应用”为课堂主线,“感知用”为指引思想,有利于提高教师驾驭课堂的能力,激发学生的学习主动性,并且让课堂散发生长的气息.

“三一三”组块教学的实施原则

课堂是促进学生生命成长的场域“,三一三”组块教学模型给予课堂生长的力量,是实现课堂生长的有效途径之一。教师在开发教学资源（三A）时要尽可能寻求学习挑战度、时空开放度、资源友好度等方面的适切,在设计创造性实践活动（三B）时要尽可能追求多元,提高学生的学习参与度、身心愉悦度和活动自由度。唯有如此,学生的生命成长才能在课堂上真实发生。

“三一三”组块教学基本模型及变式应用——以初中物理教学为例

我校把学生的“生长”作为课堂教学的主张与价值追求,在长期的教学实践中,逐渐形成了学校的课堂教学特色,我们称之为“三一三”组块教学模型。以物理学科教学为例,阐述“三一三”组块教学基本模型及变式的运用之道。

循“生长”课堂之道 塑“三一三”教学之型

立足“生长”的课堂蕴含着生本、生命、生成、生活、生态等元素,致力于创设以人为本、基于生活和和谐共生的教学场域,使儿童的生长呈现出勃发向上的生命姿态。我们基于学校课堂改革的研究与实践,深入讨论生长课堂中“生长”内涵的五个方面及相互关系,总结提炼促进学生“生长”之道——“三一三”组块教学模型,并阐述这种模型的结构、内涵和四个基本特征。

基于“三一三”教学模型的“七说”备课——以“人的性状和遗传”一节为例

以"人的性状和遗传"一节为例,从教材、学情、目标和模式、设计、教学法、评价和计划7个方面阐述基于"三一三"教学模型的备课。学校推出每周1次的"七说"备课,便于教师整体把握教材、课程标准、学情、教学方法、评价策略等,为上好每节课打下坚实的基础。经过近2年的实践,生物学课堂更加有效,学生学习积极性更高,教师成长更快。

Schemes for Probabilistic Teleportation of an Unknown Three-Particle Three-Level Entangled state

In this paper, two schemes for teleporting an unknown three-particle three-level entangled state are proposed. In the first scheme, two partial three-particle three-level entangled states are used as the quantum channels, while in the second scheme, three two-particle three-level non-maximally entangled states are employed as quantum channels. It is shown that the teleportation can be successfully realized with certain probability, for both two schemes, ira receiver adopts some appropriate unitary transformations. It is shown also that the successful probabilities of these two schemes are different.

The Trinity Triangle and the Homonymy of the Word ＂Is＂ in Natural Language

There are philosophers and logicians who do think that the Trinity-triangle makes up an evident formal-logic inconsistency demonstrating convincingly that Christian faith is illogical and hence irrational one. The present paper submits a systematic counter-argumentation against such thinking. According to the submitted counter-arguments, there is no formal-logic inconsistency in the Holy-Trinity-triangle： There is only a logic-linguistic illusion of such inconsistency which illusion is naturally produced by the ambiguity of the word ＂is＂ in natural language. The author has invented an effective remedy for that illusion, namely, a precise formulation of the generalized and thus modernized Guillotine of Hume by means of an artificial language of two-valued algebraic system of formal ethics of moral rigor. Systematical using the mathematized formulation of the generalized Hume＇s Guillotine cuts down the mentioned linguistic illusion of logical inconsistency. Thus, the paper essentially interconnects discrete mathematical representations of formal iogic of thinking and formal ethics of acting. In relation to contemporary symbolic logic, the author submits not a technical result solving some important particular problem concerning some specific system of symbolic logic but a significantly new result of conceptual work concerning logic in general and its interconnection with mathematical ethics. The old idea of logic as a moral science is transformed into a novel idea of symbolic logic as a brunch of mathematical ethics. In particular, two-valued algebra of classical formal logic is considered as a particular case of two-valued algebra of formal ethics of moral rigor. The submitted conception of logic is instantiated by applying it to the knotty logic-problem of Holy-Trinity-triangle.

An automatic unified modeling method of geological object and engineering object based on tri-prism(TP)

For the interaction relation between geological object and engineering object in some fields related to water conservancy and hydropower, a unified modeling idea was proposed. On the basis of summarizing both advantages and disadvantages of existing modeling methods, an automatic unified modeling method of both engineering and geological objects based on tri-prism(TP) model was presented. Through the lossless correction algorithm of deviated drill holes contained in this method, the real deviated drill holes could be corrected into the equivalent virtual vertical ones. And the correction accuracy fully meets the requirements of unified modeling. With the virtual vertical drilling data, TIN construction of both cover layer and other stratums would be built in order to obtain the 3D geological model. Then, the engineering design data would be introduced into the 3D geological model for achieving unified modeling. For this process, the volume subdividing and restructuring principles were introduced to deal with the spatial relationships between engineering object and geological object. In order to improve the efficiency of unified modeling, the reconstruction of TIN based on constraint information was also applied in this method. At last, the feasibility and validation of the unified modeling method as well as its relevant key algorithms were verified by specific experiments and analysis of results.
