Leon Lederman is engaged in a valiant campaign to renovate the teaching of physics in high school (Physics Today, Physics Today 0031-9228 549200111 https://doi.org/10.1063/1.1420496September 2001, page 11 ). At the center of his campaign is a modification of the order in which the different sciences are taught in the high-school curriculum: Instead of physics last, teach physics first.

The Europeans have cut this Gordian knot by teaching all sciences simultaneously. In France, for example, in the years that correspond to US middle school and high school, the schedule is approximately as follows: Math is taken four hours per week for all seven years; physics (with some chemistry), four hours per week the last six years; biology and natural sciences, three hours per week all seven years; and information science and technology, one hour per week for the first four years. Although student options are limited, the last three years will differ somewhat depending on whether the student chooses a more literary or scientific path.

Rather than start new pilot projects in the US that parallel the French schedule but will take at least 10 years to evaluate, one could perhaps obtain a more immediate evaluation by comparing US and European results in the 20- to 30-year-old groups. That is finally where differences will count, rather than in test results at the end of the school year.
