项目实践学习过程的渐进达成机制探索

本文从项目需求设计、学习环节设计、形成性量规设计、量化与质性评价方法等角度对项目实践学习过程的形成性评测进行了分析。文中提出知识链与能力链融合驱动的方法进行项目需求设计,利用自底向上的融合与支撑设计方法进行学习环节设计,兼顾知识逐步巩固与能力逐层提升。文中提出引导性、精细化、可量化的量规设计方法,建立增量和存量交替形成的渐进达成实施路径。运行与控制二级项目实践表明,本文提出的形成性评价机制深入学习过程进行观察和评估,能够及时发现问题并做出改进,对学习达成有较好的保障作用。     

半交替类目

半交替类目源于交替类目,是对交替类目内容范围的进一步诠释,处于交替类目的地位,却具有交替类目的性质和使用类目的性质,实际处于半交替状态,致使交替类目的应用出现了许多繁杂的情况,只有回到中图法中,才能认识清楚其交替使用的内容范围,做到辨类和标引的准确。

“链+”课堂 回味无穷——以“探索特殊两位数相乘的规律”教学为例

“链+”课堂中整个教学过程一般由四个部分组成：建构“链源”、深度“链究”、合理“链构”、即时“链评”.其中深度“链究”是课堂的主体部分,根据教学需要由“合理猜想”、“深度探索”、“巩固训练”这些环节灵活交替地进行,这样的课堂教学充满数学味,让数学回味无穷.

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.
