How do children learn?

Model based on the empty headconcept

Teaching is a transfer ofinformation to fill the space

Does not work! Why?

No matter what the topic, childrenhave their own ideas

And they believe them


6/50

Learning

Knowledge is not

absorbed by thelearner

It is constructed

The process cannot beobserved


7/50

Constructivist ideas

10/50


Learning is based on what the

learner already knows

New ideas presented byexperience or instruction may :

fit in with existing ideasnot relate to ideas already held

challenge existing ideas


11/50


New knowledge may be

linked to existing ideas inappropriatelycreating a misconception

retained unconnected

rote learning

linked to existing ideas

meaningful learning


12/50


Retrieval of previous learning usesnetworks of knowledge

Recall is efficient only wheninformation has been storedmeaningfully

Summary

Constructivism accepts that ...

children already have their own ideas new knowledge must be integrated with

existing knowledge

existing networks of knowledge may bechallenged by new ideas

existing ideas are strongly held


14/50


Many sets of ideas aboutconstructivism

Importance of

social interactions

language Process of learning cannot be

directly observed


15/50

Research findingsabout childrens

ideas


16/50

Childrens ideas - research

Two important findings

Children have very strongly held ideas

Existing ideas can co-exist with new ideas

Used in different circumstances

Most children share the same set ofideas

Common misconceptions

Sources of childrens ideas

Where do childrens ideas come

from ?

How have they been formed ?

Everyday experience produces

learning importance of language and learning

from listening


19/50

An Example - SEEING

Example

Often hear people say that theythrow a glance

Children develop the idea thatseeing is an action

Childrens drawings reveal this


20/50

An Example - SEEING

Sources of childrens ideas

How have these sources led to aset of common misconceptions?

Common experiences of children

Widespread use of same ways oftalking about science ideas thatoccur in everyday experience

Heavy objects fall faster than light

objects

Idea comes directly from experience

There is no gravity on the moon

Idea comes from seeing

weightlessness in space

Thats why moon suits have big heavy

boots

28/50

Sorting out yourown science ideas


29/50

Sorting out your ownscience ideas

Drawing concept maps

Encourages the linking of ideas

Encourages discussion to sort outown ideas

Fits a social constructivist approach


30/50


Concept maps contain propositions:

for example:
