Rational Grammar School Arithmetic (Classic Reprint) - Tapa blanda

Sinopsis

Excerpt from Rational Grammar School Arithmetic

The present book is an outgrowth of the notion that arithmetic as a science of pure number, and arithmetic as a school science, must be treated from two essentially different stand points. Viewed as a finished mental product, arithmetic is an abstract science, taking its bearings solely from the needs of the subject; but viewed as a school subject, arithmetic should be an abstracted science, taking its bearings mainly from the needs of the learner. The former calls only for logical treatment, while the latter calls for psychological treatment as well. In other words, to be of high educational value the school science of arithmetic must take into full account the particular stage of the pupil's development. The abstract stage must be approached by steps which begin with the learner, rise with his unfolding powers, and end leaving him in possession of the outlines of the science of arithmetic. To break vital contact with the learner at any stage of the unfolding process is fatal. A controlling principle in the development of the various topics of this book is that any phase of arithmetical work, to be of value, must make an appeal to the life of the pupil.
