The reformer of teaching mathematics

The reform committee of mathematics declared at the Meran general assembly of nature examiners in Germany in 1905 that sciences also represent cultural values, not only practical benefits: therefore, they are worth being considered equal to linguistics as means of education. In Hungary the reform was conducted by Prof. Manó Beke. He, together with

. He was granted the French ''Officer d'Académie'' in 1910. In 1906 the Mathematics Reform Committee was established in Hungary, the chairperson of which was Manó Beke, its secretary was Sándor Mikola and the members included László Rátz as well. This committee performed admittedly the most productive work among the European committees. László Rátz and Sándor Mikola, as they found the changes necessary, had worked out the workable methods and curriculum of mathematics teaching. They declared that certain elements that are obtained indirectly belong to mathematics as well and they have to be confirmed in the student. The learning of mathematics has to be completed by immediate experience and lots of measuring. They also emphasized the need for mental calculation and the practice of estimating. According to their theory the students have to be encouraged to tend to know reality. They considered inevitable for the teachers to intend to form clear ideas. Finally, their brave initiatives were successful: in November 1909 Rátz and Mikola were officially permitted to teach mathematics in the Lutheran Gymnasium as they found it desirable in accordance with the reform endeavours. From the beginning he was an active participant in a worldwide effort of science and mathematics teaching education reform; from 1909 he gets official full liberty in improving educational methods in his own high school; he becomes ''Officier d'Académie'' award at a 1910 Paris congress. The objectives of this reform were the recognition of cultural and humane values of science education, besides tangible pragmatic values. According to the objectives, mathematics has important involuntarily acquirable subconscious elements that need to be enhanced in students. The teachers strived to deliver clearly articulated concepts at the voluntary, conscious level, but more importantly, learning of mathematics has to be tightly woven together with direct experience and practice, emphasizing mental calculations and practicing estimations, allowing students to acquire a subconscious knowledge of reality from experience with quantitative relations.


Eugene Wigner about his teacher László Rátz

Eugene Wigner Eugene Paul Wigner (, ; November 17, 1902 – January 1, 1995) was a Hungarian-American theoretical physicist who also contributed to mathematical physics. He received the Nobel Prize in Physics in 1963 "for his contributions to the theory of th ...

(in 1963), Dr. Eugene Wigner said:
... there were many superb teachers at the Lutheran gymnasium. But the greatest was my mathematics teacher László Rátz. Rátz was known not only throughout our gymnasium but also by the church and government hierarchy and among many of the teachers in the country schools. I still keep a photograph of Rátz in my workroom because he had every quality of a miraculous teacher: He loved teaching. He knew the subject and how to kindle interest in it. He imparted the very deepest understanding. Many gymnasium teachers had great skill, but no one could evoke the beauty of the subject like Rátz. Rátz cared deeply about mathematics as a discipline... He took special care to find his better students and to inspire them. Rátz felt so privileged to tutor a phenomenon like Neumann Jancsi that he refused any money for it... Who could know that this precocious 10-year-old would someday become a great mathematician? Somehow Rátz knew. And he discovered it very quickly. Rátz was just as nice to me and nearly as devoted as he was to Neumann. Rátz was the only gymnasium teacher to invite me into his home. There were no private lessons. But Rátz lent me many well-chosen books, which I read thoroughly and made sure to return in good condition.
