The American high-school geometry curriculum was eventually codified in 1912 and developed a distinctive American style of geometric demonstration for such courses, known as "two-column" proofs. [49] This remains largely true today, with Geometry as a proof-based high-school math class.
In exchange for more federal aid, the states were required to measure progress and punish schools that were not meeting the goals as measured by standardized state exams in math and language skills. [ 225 ] [ 226 ] [ 227 ] By 2012, half the states were given waivers because the original goal that 100% students by 2014 be deemed "proficient" had ...
Education in the Thirteen Colonies during the 17th and 18th centuries varied considerably. Public school systems existed only in New England.

Topics introduced in the New Math include set theory, modular arithmetic, algebraic inequalities, bases other than 10, matrices, symbolic logic, Boolean algebra, and abstract algebra. [2] All of the New Math projects emphasized some form of discovery learning. [3] Students worked in groups to invent theories about problems posed in the textbooks.

The curriculum that SSMCIS devised had influences from earlier reform work in Europe, [3] going back to the Bourbaki group's work in France in the 1930s and the Synopses for Modern Secondary School Mathematics published in Paris in 1961. [9] Indeed, most European secondary schools were teaching a more integrated approach. [14]
