Sharing the teaching experience on how to solve chemical tasks of the advanced difficulty level.

Authors:

Sidorenko S. V.. Adress: the rural community of Kvarkeno, the Orenburg region.

Summary

For the students of the 10th chemical and biological Form I’ve developed a subject-focused elective course “Solving chemistry tasks of the advanced difficulty level”. Attending this course classes allows student of senior classes to feedback, systematize, and further develop the chemistry knowledge, to master main approaches to solve non-standard qualitative and quantitative tasks on organic and inorganic chemistry, develops their thinking. Mastering strong knowledge within the framework of chemical education, the most important computations skills, algorithms of typical tasks solving, encourages successful work within the given course framework. Besides, chemical intuition and power of observation are needed. Their clear arrangement and structuring in accordance with general types and ways of their solving is important to teach how to solve tasks, which call the major difficulties students encounter.
