How to Eliminate Critical Points of Initial Chemistry Education - Examples of "Solution Composition" and "Salts Nomenclature"
Abstract
Within the OP RDE project "Didactics: Man and Nature A" is one of the goals of identification and possible improvement of so-called critical points of the initial science curriculum. In the interviews with chemistry teachers from the lower secondary schools was identified as critical point the chemistry topics with quantitative character.
To master such part of chemistry curriculum, an appropriate mathematical apparatus is needed, a comprehensive understanding of applied principles, as well as largely developed abstract thinking and orientation in structures and contexts. The paper focuses on two model examples of identified critical points of initial chemistry education at lower secondary schools, namely the solutions composition and the salts nomenclature.
There are discussed the starting points and conditions of realization and proposals of innovations and changes of the conception of teaching these topics in cooperation of subject didacticians with teachers of lower secondary schools within the project of the so-called community of practice.
