International Survey |
We invite you to
study this web page though the page
still is under
construction.
Basically we will
give a small international survey about the actual use of calculators
in
primary schools. There also is another web site which reports from TIM
projects with calculators in Germany.
We also refer to
and reflect on mental
processes of learning and
understanding mathematics when using calculators and we touch the
delicate question about the future of paper & pencil skills. Thus
we recommend also to study the separate web site
Discussion Forum on the Future of Paper & Pencil Skills
It is
impossible to give an international survey. On this web page we just
will try
to summarize some experiences from different countries. Most of the
information
was collected by Christina Ebbing-Rupieper and Hartwig Meissner on
international conferences, through
personal communication and via correspondence. Additional comments are
welcome,
they will be added here whenever possible. We also recommend to study
the
references added at the end.
In 1986 -
1989 there was an important Calculator-Aware-Number
(CAN) Project
in England
and Wales, “a curriculum development project
… the aim of which was to
study effects that the availability of calculators would have on the
mathematics curriculum of primary schools” (Shuard, H. et al., 1991).
Ruthven (1999, 2001a) analyzed some of the complexities
of
developing such a curriculum. But “During the 1990's, [the] curriculum
and
assessment system [became] much more 'calculator beware'
as a result of opinionated criticism of calculator use by
mathematicians and politicians which received wide publicity. This
climate, and
the circumstances it has produced in schools, have made developmental
research
on calculator integration virtually impossible” (Ruthven 2007, personal
communication).
In Germany
there is no federal curriculum, each Land
(= state) is responsible for itself in education. Regarding the
syllabuses for
mathematics education in primary schools from the 16 German Laender we
must
summarize that paper & pencil algorithms still play the dominant
role and,
that calculators are not mentioned at all to replace them in any kind
of
activities. There are only a few investigations in primary schools by
individuals or small research groups how calculators could be or should
be used
in the future in mathematics education.
In Sweden
calculators are allowed in each grade. It depends on the teacher how
and how
often the calculator is used. Swedish school books touch the topic
calculator
quite differently. Some offer many exercises to use calculators and
others do
not. According to the syllabus the children must have learnt till the
end of
grade 5 to compute mentally, to compute by the use of (reduced) paper
&
pencil algorithms and to compute with calculators (Hedren 2001).
In Norway
the situation is similar. Starting with grade 2 (age 7) “pupils should
have the
opportunity to … experiment
with large numbers and symbols,
examine arithmetic operations and use calculators and computers” (http://Skolenettet3.1s.no/97_eng/Curriculum,
13.11.2002). The use of calculators is included in school books, but “many decisions
related to the use of calculators in primary schools are left to the
teacher”
(Brekke 2001).
In the Netherlands
officially the use of calculators starts in grade 7 (age 11), but it is
allowed
to work earlier with calculators. Many textbooks contain activities for
calculator mathematics, but many teachers will deny these activities or
exercises. “On the other hand in Dutch mathematics education for
primary
schools there is a strong movement – an intention – to reduce
paper-and-pencil
maths, especially the traditional algorithms. In the place of these
algorithms
mental arithmetic is introduced as an alternative, and calculator math
as well
(ter Heege 2001).
There are
also many calculator investigations in North
America. In a meta-analysis
Hembree and Dessart evaluated 79 studies (grades K – 12) and got the
conclusion
that calculators should be used in all grades: “It no longer seems a
question
of whether calculators should be used along with basic skill
instruction, but
how” (Hembree and Dessart 1986, p. 97). But in reality also in the US
this
research result is not accepted unanimously. Ralston analyzes and
refutes (in Ralston 1999) the
arguments made by "back-to-basics" proponents against the use of
calculators And on the web site http://www.doc.ic.ac.uk/~ar9/LDApaper2.html
he argues: “The truth
is that few can be expected to make sense of arithmetic if
…
teachers are supposed to act as if the calculator and computer
had never
been invented.”
There will be reports from the conferences in Karlsruhe, Berkley, Adelaide, Budapest and following. (See also the TIM papers # 48, # 63, # 70 and # 71 in List 1 of References)
