In recent years, many mathematicians argued whether
mathematics teaching and learning should begin with contexts or not. In 2007 in
California, some people claimed that a mathematical approach that focused on
number sense using contexts will be a detrimental to children (Sowder, 2007). Some
researchers also showed that abstract examples were more advantageous for
students (Kaminski, Sloutsky & Heckler, 2008; Kaminski & Sloutsky, 2012).
They stated that concrete instantiations prone to distract students’
concentration in doing transfer task. This lead teachers begin to doubt the
importance of involving contexts in teaching learning activity. The role of contexts
in the classroom is questioned. How important contexts are in learning
mathematics, this paper will discuss this questions.
In the past, people tend to see students as an empty
vessel and ready to be filled with knowledge. However, they come to classroom
bringing a lot of daily experiences. On the other hand, mathematics is abstract
and difficult for students to learn. To help them understand it, teachers use
models to make it familiar or concrete. Familiar models for them are
everyday-life experiences known as contexts (Gravemeijer, 2011). In realistic
mathematics education, students construct mathematics by mathematizing these
contexts through concrete examples. Contexts make mathematics become meaningful
for them (Freudenthal, 2002). As a result, students will easily understand and
build concepts of mathematics.
Concrete examples are also the source of concept construction
and the zone of application (Leen Streefland, 1991). The source of concept
construction means mathematical concepts are originally maintained on daily
life problems and students learn it informally. If this source of concept are
brought up in a classroom, children will understand it easily. A research by Carraher
et al (1985) showed that those who have difficulties in doing computation at
school are able to do it when buying or selling at the market. Contexts are not
only helping children build their mathematics but also as the zone of
application. The benefit is students will have many experiences of the
application of mathematics in their daily life.
In some
research, contexts successfully support students in understanding mathematics
under right circumstances (Brown, McNeil & Glenberg, 2009). De Bock et al also
provided evidences on his research that those who learn mathematics with
concrete models did transfer task better than abstract learners (De bock,
Deprez, Van Dooren, Roelens & Verschaffel, 2011). They conclude that
students can reach a higher level of abstraction than those generic group. This
proves that the use of contexts in mathematics classroom are crucial for
students.
