Excerpt from The Texas Mathematics Teachers' Bulletin, Vol. 11: No. 2

A preliminary training in the use of letters in the last year of the grades will prepare the student for the be ginning of formal algebra in the first year of the high school. The negative number which is so difficult to the beginner may then be given and formal algebra introduced. By thus leading the student into one difficulty at a time he is able to progress more intelligently than when the double abstraction of letters and negative numbers are given at the same time. This pedagogical mistake is made so far as we know in no other country except in our American schools.

Another, pedagogical error made in our schools is to define for the first time certain geometrical magnitudes in the second or third year of the high school and then begin in the same lesson to give logical proofs of properties and relations of those quantities. In educational systems of other countries two to three years preliminary training is given before logical or formal proofs are attempted. This is generally done by definitions, drawing, constructions, measurements and considerable training in the computation of areas and volumes. There are many constructions, measurements, and drawings that Should be made to familiarize the student with the quantities about which he is to make later logical deductions.
