仔细研读近几年各省化学高考试题,能力的考查尤为突出,如对考生获取化学信息知识并进行有效提取、加工吸收、整合重组能力,化工工艺流程图分析能力、观察能力、逻辑推理能力等的考查。在平时教学实践中,如何有效甚至高效地培养学生的各项能力,教材是最好的一种教学素材。充分挖掘和利用教材,在课堂教学中有效培养学生的能力。一、充分利用教材,培养学生评价和分析“实验方案和化工工艺流程”的能力例如,苏教版《有机化学》54面:“两种生产异丙苯工艺的对比”教学内容的利用,培养学生评价“实验方案和化工工艺流程”的能力。课堂教学中引导学生认真阅读教材第二自然段并仔细观察图3-12(如图1所示),
Careful study of provincial chemical college entrance examination papers in recent years, examination of competency is particularly prominent, such as candidates access to chemical knowledge and knowledge extraction and effective, processing and absorption, integration and restructuring capabilities, chemical process flow chart analysis, observation, logical reasoning ability test. In normal teaching practice, how to effectively and efficiently develop students’ abilities, teaching materials are the best kind of teaching material. Fully tap and use teaching materials, effectively cultivate students’ abilities in classroom teaching. First, make full use of teaching materials, training students to evaluate and analyze “experimental program and chemical process ” ability For example, the Soviet version of “organic chemistry” 54 surface: “two kinds of cumene process comparison ” teaching content The use of training students to evaluate “experimental program and chemical process ” ability. Classroom guide students to carefully read the second paragraph of the textbook and carefully observe Figure 3-12 (Figure 1),
