加深——课改新增知识点难度深究新课标中增加了一些新的知识点,如化学平衡常数、难溶电解质的溶解平衡常数、熵变和焓变、核外电子排布式、手性异构等,这些知识往往是与大学高等化学接轨点。在2007年的新课改区的高考题中均涉及了平衡常数,但是大都停留在定性的判断层次上。2008年的高考新课改区就涉及了化学平衡常数和难电离平衡常数的计算问题,大有将“深究”的趋势!
Deepening——The difficulty of adding new knowledge points to the curriculum reform. Some new knowledge points have been added to the new curriculum, such as the chemical equilibrium constant, the dissolution and equilibrium constant of the insoluble electrolyte, the entropy change and transmutation, the electronic arrangement outside the nuclear, and the hand Sexual isomerism, etc. These knowledge are often in line with the university’s advanced chemistry. In the 2007 new curriculum reform district college entrance examination questions all involved balance constants, but most of them remained at the level of qualitative judgment. The new curriculum reform area of the 2008 college entrance examination involves the calculation of chemical equilibrium constants and difficult ionization equilibrium constants, and there is a tendency to “deep study”!
