Excerpt from Chemistry
The author claims to have been one of the first to put to a complete test in the laboratory the suggestions of that "inspiring tract" - the Report presented at the Newcastle-upon-Tyne meeting of the British Association by the Committee formed to investigate the methods of teaching chemistry. He wishes to record his indebtedness to that Committee, whose efforts set teachers of subjects other than Science thinking and experimenting. The path of adventure and discovery was opened to many a boy and girl who would otherwise have trodden the damp and muddy ways of test-tube analysis.
The short time available and the ever-changing classes render strict adherence to the "heuristic" method impracticable, while many recent discoveries give us direct paths which make it tedious and unnecessary to follow the "historic" method.
The course given in this book is the result of experience. It should be completed in two years by a class (aged from 12 to 16 years) working for two hours per week.
There is constant reiteration of fundamental facts and very little revision should be necessary if the examples are systematically set and exacted for home-work.
