**Zoltán Dienes, Dr.**

(1916-2014)

Born in Budapest, Hungary in 1916 from Hungarian parents: Paul Dienes
and Valeria Geiger, the brother of Gedeon Dienes.
Schooling in Hungary, Paris and England, matriculating from Dartington
Hall School, Devon, England in 1934.
Studied Latin, German, Pure and Applied Mathematics 1934-37 Obtained
B.A. degree with Honours in 1937 from the University of London, Ph.D.
degree from the University of London in 1939, thesis on
"Constructivist Foundations of Mathematics According to Borel and
Brouwer."

He married a very young Tessa...Mina Joyce Cooke as registered at
birth, They had five children: Corin - now Jasmine, Nigel, Jancis,
Sorrel - now Sarah, Bruce and a great number of grandchildren and great-grandchildren.

After school teaching experience at Highgate School and
Dartington Hall School and after teaching at the Universities of
Southampton, Sheffield, Manchester and Leicester he became research
fellow at the Center for Cognitive Studies at Harvard University
1960-61, associate professor in Psychology at Adelaide University
(Australia)1961-64 after which he was appointed director of the
Psychomathematics Research Centre in Sherbrooke Quebec 1964 - 1975.
After the Centre was closed down for political reasons, he worked for
native education as Professor at Brandon University 1975-78.

During this time as well as in later years (1978-80) he acted as
mathematics consultant in several countries (Italy, Germany, Hungary,
New Guinea, United States) and for different organizations
(OEEC,Unesco) all over the world. He also founded the International
Study Group for Mathematics Learning (ISGML) in 1964 (Please refer to
Bulletin, Vol. 1, No. 1, December 1962, describing the initial ISGML objectives).
The objectives of the ISGML, as stated for its 1969 official
incorporation, are the following:

A: To investigate and research the processes of learning mathematics,
languages, art and allied disciplines;

B: To apply the results of this research to the educational process in
these respective fields;

C: To hold international conferences to discuss, plan and promote the
above research and their educational applications.

When the Sherbrooke Research Centre was closed, the temporary
headquarters of the ISGML were moved to London, England, and the
Vice-President, John Williams, of Ealing Technical College, St. Mary's
Road, London, W.5. became acting president.

In the 1980s and at the start of the 1990s beside working in Italy,
Spain USA,Hawai Greece and Hungary he returned to Canada and later he
was associated with Acadia University in Wolfville, Nova Scotia, being
elected a Research Associate by the Psychology Department. He lives
now in Wolfville with his daughter Sarah.....

Here is what he says, in his own words, of the main essence of his life's
work:

My interest in mathematics goes back to childhood and early youth.
Along with most mathematicians, I felt, quite early, the fascination
of the purely abstract. At quite an early stage, a fascinating problem
seemed to me why mathematicians were divided, if rather unevenly,
between formalists and intuitionists. This interest found expression
in my doctoral thesis in which I tried to compare Borel's mathematical
realism with Brouwer's intuitionism.

Later, in a more objective mood, I tried to put a price tag on
mathematical notions and theorems through analyzing the assumptions in
terms of quantifiers and their uses which had to be made to define
these notions or to prove these theorems. I spoke about this work at
Turin University in 1951 and published my considerations in the
reports of the Turin Mathematical Seminar.

Some time after this, as I became interested in the problem of why
mathematics was found difficult by most people, I wondered whether the
difficulties in the foundations of mathematics had not something to do
with the difficulties that children experienced in understanding
mathematics.

I chose the age of ten as a reasonable stable period of childhood and
ran a concept formation experiment on a representative sample. I
first reported the results of this experiment at the Psychology
Institute in Florence, Italy, and published my preliminary findings in
the article, Sulla Relazione Fra Ia Formazione dei Concelti Astratti e
Ia Struttura Della Personalitd, 1957, Bollettino de Psicologia e
Sociologia Applicata, Firenze, Italy. I tried, in a small way, to
reorganize mathematical work in some classrooms, turning the
classrooms into laboratories of discovery and construction, using
specially designed materials which later developed into the now
well-known multi-base and algebraic materials. It was impossible to
contain the experiment as a psychological one because of its immediate
and unqualified success. The experiment turned into a mathematics
project throughout the County of Leicester, England. During this time,
1958-59, I worked out, through practical ways, some principles which
should account for the success observed. These were written up and
published in the article, The Formation of Mathematical Concepts in Children Through Experience, 1959, Educational Research, London, England.
With the results of previous experimental work done in England, I
proceeded to Australia to work in the psychology department of
Malcolm Jeeves. This time we tried to dissect our problem into some of
its identifiable component parts. We observed the learning of
structure both in classroom situations and individually. The
individual experiments were designed so that subjects were obliged to
externalize their thinking behavior so that it could be accurately
observed and noted. The Report of the first round of this work is
contained in the book, Thinking in Structures, 1965.

Other experiments followed on a larger scale largely confirming the
results of the first round and generating further hypotheses for
further experiments. The work is reported in, The Effects of
Structural Relations on Transfer, 1966.

Another very interesting chapter in these attempts is the introduction
of mathematics learning to the native schools in Papua New Guinea. The
first attempts were sketchy but soon there was a team of about a dozen
enthusiastic operators, coordinated by myself as chief consultant,
whose job was to bring insightful mathematics learning to the bush.

The eventual result of these efforts was the formation of a group,
comprising teachers from Government as well as Mission schools, with
whom I met regularly, eventually several times a year, to work out a
mathematics program suitably adapted to the needs of the native children.
During these investigations it transpired that in all cases real
mathematics learning, as opposed to drill whose purpose is the
reproduction of certain responses, given certain stimulus situations,
involves the use of creativity. The Sherbrooke work touched upon
different forms of artistic expression. Preliminary field trials were
conducted to ascertain the relationships between abstraction,
generalization, representation, symbolization and formalization. Some
tests were developed to test the important side-effects of mathematics
learning, such as increased learning ability, tendency toward
structuring, performance in structural thinking, preference for complexity and the like.
In my old age I have also contributed to a family anthology of poems,
in which there are poems written by three generations of my family,
including my wife Tessa and some of my grandchildren. I also published
a whole cycle of poems written by myself: "Calls from the past" in
which I touch on the problems of mathematics learning, as well as use
the medium of poetry to describe some salient events in my past.

Finally, in the May 1999 number of the Canadian Friend I
have an article in the form of an open letter entitled:
"To be or not to be a Christian"
in which I raise some fundamental questions about life and of what
there might be afterwards.

Z.P. Dienes published several books and many articles in many
languages in the field of teaching mathematics, in psychology and in
pedagogy and made also films about his method.
