This research will consider fractions as a topic
for adult numeracy. Difficulties adults face inherent in the
definition, computation, cognition, and usefulness of fractions will be
considered, as well as effective teaching presentation styles for
fractions. It is anticipated that this research will result in specific
suggestions for adults learning this area of mathematics, such as
alternate language, approach and methods.
Literature review
Not
just in britain, but across europe there is increasing concern
regarding the numeracy skills of adults. For example, the adult basic
skills strategy unit, in concert with the european social fund,
launched a numbers in everything campaign in 2004 to address the issue
of adult numeracy (niace 2006). Respondents to the skills for life
survey performed at lower levels on numeracy assessment than on
literacy assessment (dfes 2003, 18). The adult math project addressed
concern regarding numeracy issues amongst adults as far back as 1978
(evans 2000).
One of the reportedly most despised and difficult
areas of mathematics in the minds of adults is fractions; many adults
have difficulties with fractions as they had difficulty learning
fractions as children, no longer practice them after leaving school,
and rarely use fractional computations in their everyday life (chinn
2004).
Adults first have difficulty defining what a fraction
entails; for most it is simply one number written above another with a
line inbetween (chinn 2004). There is little understanding of the
relationship inherent in fractions, or of fractions beyond a single
unit as whole. Many separate the mathematical representation of
fractions they learned in school from the deeper fractional concepts
these mechanical manipulations represent (chinn 2004). Theunissen
(2005) discusses the complexity of fractions, presenting them as
division, as position, as process, and as algorithm. Few adults have
this level of understanding of the definition or complexity of
fractions. In addition, words used in fractions and related mathematics
are often misused or present barriers to those attempting to learn
(chinn 2004).
Mathematics instruction has traditionally focused on
solving rather than understanding, particularly at the primary school
level, where fractions are most typically introduced (evans 2000). In
school, fraction computations are usually presented as a series of
steps or methods to be memorized. The idea is that working these
mathematical problems will lead the pupil to an understanding of the
concpets behind them (gal 2002). However, this is often not the case.
Gal (2002) contends it is “important to acknowledge the difference
between mastery of computational and procedural skills and much broader
understanding of principles and underlying ideas”(21).
In the area
of cognition, learning fractions should lead to an understanding of
proportional reasoning, a vital life skill (chinn 2004). Some adults
were unable to master the computational processes of fractions when
they were presented with them as children, but are able to master the
computations when they approach the maths later in life (evans 2000).
Unfortunately, “mathematical learning is a cumulative process so that a
poorly developed concept of number can affect the acquisition of number
facts and by the same token, poor arithmetic ability can compromise the
growth of mathematical knowledge” (chinn 2004, vi). This can lead to
poor self-efficacy in mathematics, difficulties in advanced maths, and
math anxiety. Evans (2000), for example, provides extensive coverage of
how math anxiety and other barriers to adult learning develop from
childhood experiences.
Further, adults often question the usefulness
of fractions in their everyday lives. Part of this results from
emphasis on the computations of fractions rather than the cognitive
understanding of proportional reasoning. Caunt (2001) contends “there
is an overemphasis on the need for adults to have numerical skills to
check that figures are correct, rather than on the need for numerical
awareness to analyse and interpret what information is being
presented”(19). “quantitative skills desired by employers are much
broader than mere facility with the mechanics of addition, subtraction,
multiplication and division and familiarity with basic number facts;
they also include some knowledge of statistics, probability, mental
computation strategies, some grasp of proportional reasoning or
modeling relationships, and broad problem-solving and communication
skills about quantitative issues” (gal 2002, 22).
To assist adults
in developing these conceptual and computational skills, teaching
methods and language that relate what is being taught to life
experience is vital (chinn 2004). Experiential learning is an important
method for education at any level, but must be reformatted in many
cases to be appropriate for an adult learner. For example, pouring
water and sand is fine for children, but may not be as readily accepted
by adult pupils.
Overall, literature supports that most adults
dislike fractions because they do not understand them. This makes
working fraction problems mechanical and without meaning. Further,
although they are likely to see them as less useful in their everyday
lives, fractions represent an important conceptual area necessary for
productive workers and citizens (niace 2006).
Methodology
As
the reasons for adults' difficulties and dislike of fractions are
likely to be complex, a qualitative research method is planned.
Specifically, two focus groups are planned. The first focus group will
consist of six to ten adults will be undertaken. This focus group will
hopefully be comprised of adults from a spectrum of backgrounds,
including different social classes, ethic backgrounds, and educational
attainments. The unifying criteria of the group will be that all
participants must have had difficulty learning fractions and dislike or
disliked this area of mathematics. A set of open-ended questions will
be designed to spur the group on to discussion regarding difficulties
in mastering fractions, fractions' usefulness in everyday life, and
various teaching methods experienced by participants. The second focus
group will be of adult educators who teach mathematics. A series of
open-ended questions will also be planned to guide this group, but with
focus on teaching methods. Both focus groups' discussions will be
recorded, with the transcript then coded and statistically evaluated.
