As a professional mathematics educator, links to professional organisations are very important to me. My responsibilities vary from time to time, but at present my main professional interests are described below, along with some links to organisations in which I am currently less active:

The Australian Association of Mathematics Teachers (AAMT)
AAMT is the major professional body for mathematics teachers in
Australia, and comprises a federation of Affiliated Associations,
of which MAWA is one. I have previously served terms of office
as a Councillor of the AAMT. A recent AAMT role has been that
as Executive Editor of The
Australian Mathematics Teacher, the Association's journal
for mathematics teachers of students aged about 11-16 years. I
am also a member of the Editorial Panel of The
Australian Senior Mathematics Journal, directed to the
needs of mathematics teachers of older students. At present, I am the President-Elect of the AAMT, and will serve a two-year term as President from 1 February 2004.
The Mathematical Association of Western Australia (MAWA)
MAWA is the main body for mathematics teachers in WA, providing
a range of activities for Members, students and others. I am an
Honorary Life Member of MAWA and have previously held a number
of positions, including President.
Australian Subcommittee of the International Commission
on Mathematical Instruction (ASICMI)
This group is appointed by the Australian Academy of Science,
and is Australia's main offical link to the work of ICMI.
Among other things, ICMI organises the 4-yearly ICME conferences
and occasional regional conferences. Information about current
ICMI activities can be obtained through the ICMI
Bulletin. I have recently completed a term as a member of ASICMI. A major responsibility
at the moment is the ICMI Study on Algebra, which was proposed
by ASICMI and accepted by ICMI. This Study will include an international
conference and eventually an associated book-length publication. Further details are available online.

National Council of Teachers of Mathematics (NCTM)
The NCTM is the major professional body for mathematics teachers
in the USA. It undertakes a large variety of functions for both
mathematics teachers and their students. Of particular interest
recently are the Principles
and Standards for School Mathematics, available online. I
have been a member for nearly 30 years. I have not held any
offices in the NCTM, but have contributed to some Yearbooks and
written some papers for the journal, The Mathematics Teacher.

National Council of Supervisors of MathematicsNCSM)
The NCSM is the major US body for leaders in mathematics education.
As well as acting as a significant forum for discussion and professional
comment, NCSM holds an important annual conference adjacent to
the Annual NCTM meeting.
Association of Teachers of Mathematics (ATM)
The ATM is one of the two most important bodies for mathematics
teachers in the UK, for many years. It publishes two outstanding
journals, Mathematics Teaching and MicroMath.
I have been a member for more than twenty years.

Association for Mathematics Education in South Africa (AMESA)
AMESA is the major professional body for mathematics teachers
and educators in South Africa. I have been a member of AMESA for
the past several years.
International Group for Psychology in Mathematics Education
(PME)
PME conducts an annual research conference related to the many
aspects of psychology in mathematics education. PME news
is also available on the web.
Mathematics Education Research Group of Australasia
(MERGA)
MERGA is the main organisation in Australia concerned with research
in mathematics education, and organises an annual conference. I have previously been strongly associated with MERGA, having organised a conference, presented a number
of papers at conferences, convened a Special Interest Group
and held the position of Vice President. Although still a Member, I do not presently hold office in MERGA.
