“化学反应热的计算”教学设计

1指导思想与理论依据1.1指导思想转变学生的学习方式是化学新课程的一个核心理念,也是化学课程改革所追求的重要目标。教学应从学生已有的经验和将要经历的社会生活实际出发,帮助学生认识化学与人类生活的密切关系。

多重阶段的最佳决策——动态规划

本文介绍利用一种数字方法处理含有时空变化因素的复杂问题的最优决策.它与一般线性规划即有共性又有差异,但它更贴近生活,更实际,更具有普遍意义.借助计算机运算,此方法仍不失为一种最佳途径.

Curriculum Reform： Theory of Curriculum-A Starting or a Final Point of Curriculum Reform

Knowledge is essentially a human construct and it evolves continuously on reflective thinking and is practiced systematically in educational institutions. Education has to develop man＇s intellectual, physical, and spiritual powers for survival and develop enrichment factors of life through its curriculum which has certainty of content and methodology based on the educational objectives. Curriculum must build the capacity of individuals. Hence, the author defines curriculum and argues the results as better life style. Also, the author projects the expectations of the twenty-first century learners, and has extended the educational objectives to one more domain as enterprise domain, emphasizing that education must aim to develop entrepreneurial skills of learners. Therefore, it is essential that any curriculum be framed in the light of the existing curriculum, educational transaction, needs of the society, and measurable practices and evaluation, and must aim for enrichment in curricular knowledge, pedagogy and transmission techniques, and value inculcation. The author portrays the results of education.

Waste Minimization Through Process Integration and Multi-objective Optimization

By avoiding or reducing the production of waste, waste minimization is an effective approach to solve the pollution problem in chemical industry. Process integration supported by multi-objective optimization provides a framework for process design or process retrofit by simultaneously optimizing on the aspects of environment and economics. Multi-objective genetic algorithm is applied in this area as the solution approach for the multi-objective optimization problem.

构建解题模型 提升应试效率

高中属于基础教育,基础教育又属于通识性教育,高考作为选拔性考试,也会注重通法通解。因此备考建立解题模式,是提升应试效率的必要途径。一、STSE(科学、技术、社会、环保)解题模型STSE试题通常有两种命题形式:第一种是选择题,第二种为综合题。选择题将化学知识通过再'包装',考查对所学知识回忆、再认、辨认能力,背景素材主要集中在生活与医药方面。

例析高考试题中平衡常数的求法

化学平衡常数是表征气相平衡、溶解平衡、电离平衡、水解平衡等平衡体系限度的关键参数,对研究物质在可逆反应中的行为起着重要作用。2018年普通高等学校招生全国统一考试大纲的说明(理科)关于平衡常数有如下描述:'掌握化学平衡的特征,了解化学平衡常数(K)的含义,能利用化学平衡常数进行相关计算';与2016年'考试说明'相比,'了解弱电解质在水溶液中的电离平衡'改为'理解弱电解质在水中的电离平衡,能利用电离平衡常数进行相关计算','了解难溶电解质的沉淀溶解平衡。
