标题:绩效评估:是否需要创造性思维
摘要:该研究考察了 13 至 14 岁女学生的创造性思维能力与其在科学实验室解决问题的能力之间的关系.后者被各种标记为动手解决问题的任务,科学研究和绩效评估.没有提供有关如何解决问题的辅导或指导.任务中嵌入的科学概念在 13 至 14 岁学生的范围内,但任务设置新颖,在教学过程中不太可能由班主任处理.这些任务的解决过程可能涉及以下组成部分:初步试验,计划,执行,沟通,解释和反思任务,为进一步完善任务提供反馈(教育与科学部,英国,1987 年;Toh,1990 年).该论文研究了创造性思维能力与六个绩效组件中的每一个以及整体表现的相关性.

摘要:A process for the preparation of 4-trifluoromethylvalerophenone is described. The process described is a three step process comprising the synthesis of organomagnesium specie, coupling reaction between the organomagnesium specie and trifluoromethylbenzonitrile or trifluoromethylbenzoyl chloride and preferably a purification of the product obtained in suitable reaction conditions. In the process an extraction phase of the final product is not required.
