Adults
and children are frequently confronted with statements about the alarming
rate of loss of tropical rainforests. For example, one graphic illustration
to which children might readily relate is the estimate that rainforests are
being destroyed at a rate equivalent to one thousand football fields every
forty minutes – about the duration of a normal classroom period. In the
face of the frequent and often vivid media coverage, it is likely that
children will have formed ideas about rainforests – what and where they
are, why they are important, what endangers them – independent of any
formal tuition. It is also possible that some of these ideas will be
mistaken.
Many studies have shown that
children harbour misconceptions about ‘pure’, curriculum science. These
misconceptions do not remain isolated but become incorporated into a
multifaceted, but organised, conceptual framework, making it and the
component ideas, some of which are erroneous, more robust but also
accessible to modification. These ideas may be developed by children
absorbing ideas through the popular media. Sometimes this information may
be erroneous. It seems schools may not be providing an opportunity for
children to re-express their ideas and so have them tested and refined by
teachers and their peers.
Despite the extensive coverage
in the popular media of the destruction of rainforests, little formal
information is available about children’s ideas in this area. The aim of
the present study is to start to provide such information, to help teachers
design their educational strategies to build upon correct ideas and to
displace misconceptions and to plan programmes in environmental studies in
their schools.
The study surveys children’s
scientific knowledge and attitudes to rainforests. Secondary school
children were asked to complete a questionnaire containing five open-form
questions. The most frequent responses to the first question were
descriptions which are self-evident from the term ‘rainforest’. Some
children described them as damp, wet or hot. The second question concerned
the geographical location of rainforests. The commonest responses were
continents or countries: Africa (given by 43% of children), South America
(30%), Brazil (25%). Some children also gave more general locations, such
as being near the Equator.
Responses to question three
concerned the importance of rainforests. The dominant idea, raised by 64%
of the pupils, was that rainforests provide animals with habitats. Fewer
students responded that rainforests provide plant habitats, and even fewer
mentioned the indigenous populations of rainforests. More girls (70%) than
boys (60%) raised the idea of the rainforest as animal habitats.
Similarly, but at a lower level,
more girls (13%) than boys (5%) said that rainforests provided human
habitats. These observations are generally consistent with our previous
studies of pupils’ views about the use and conservation of rainforests, in
which girls were shown to be more sympathetic to animals and expressed
views which seem to place an intrinsic value on non-human animal life.
The fourth question concerned
the causes of the destruction of rainforests. Perhaps encouragingly, more
than half of the pupils (59%) identified that it is human activities which
are destroying rainforests, some personalising the responsibility by the
use of terms such as ‘we are’. About 18% of the pupils referred
specifically to logging activity.
One misconception, expressed
by some 10% of the pupils, was that acid rain is responsible for rainforest
destruction; a similar proportion said that pollution is destroying
rainforests. Here, children are confusing rainforest destruction with
damage to the forests of Western Europe by these factors. While two-fifths
of the students provided the information that the rainforests provide
oxygen, in some cases this response also embraced the misconception that
rainforest destruction would reduce atmospheric oxygen, making the
atmosphere incompatible with human life on Earth.
In answer to the final
question about the importance of rainforest conservation, the majority of
children simply said that we need rainforests to survive. Only a few of the
pupils (6%) mentioned that rainforest destruction may contribute to global
warming. This is surprising considering the high level of media coverage on
this issue. Some children expressed the idea that the conservation of
rainforests is not important.
The results of this study
suggest that certain ideas predominate in the thinking of children about
rainforests. Pupils’ responses indicate some misconceptions in the basic
scientific knowledge of rainforests’ ecosystems such as their ideas about
rainforests as habitats for animals, plants and humans and the relationship
between climatic change and destruction of rainforests.
Pupils did not volunteer ideas
that suggested that they appreciated the complexity of causes of rainforest
destruction. In other words, they gave no indication of an appreciation of
either the range of ways in which rainforests are important or the complex
social, economic and political factors which drive the activities which are
destroying the rainforests. One encouragement is that the results of
similar studies about other environmental issues suggest that older
children seem to acquire the ability to appreciate, value and evaluate
conflicting views. Environmental education offers an arena in which these
skills can be developed, which is essential for these children as future
decision-makers.
