READING PASSAGE 1



You


should


spend


about


20


minutes


on


Questions


1-14


which


are


based


on Reading Passage 1 below.



Adults and children are frequently confronted with statements


about


the


alarming


rat


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 harbor misconceptions


about ‘pure’, curriculum science. These misconceptions do not


remain isolated but become incorporated into a multifaceted, but


organized,


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


programs


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


(60%) raised the idea of 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


studied


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


pupil


(59%)


identified


that


it


is


human


activities


which


are


destroying


rainforests, some personalizing 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 1) % 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
