The ‘school science – working science’ continuum
… up to approximately Level 4,
students investigate their own ideas about science. At higher levels they
look at scientists’ ideas about science.
As their abilities and understandings develop, students progress along
a ‘school science – working science’ continuum.
- The contextual strands of Science in the New Zealand Curriculum offer
activities with a range of ‘school science – working science’
ideas.
- The curriculum levels provide reliable indications of what is appropriate
to different ages/ abilities. For example, up to approximately Level
4, students investigate their own ideas about science. At higher levels
they look at scientists’ ideas about science.
Theories
- The science student investigates personal theories,
and
- through school science, develops increasing reference
to science theories in investigations
- towards the understandings of a ‘working’ scientist,
who investigates science theories.
Gathering data
- The science student uses senses to gather data, and
- through school science, develops increasing use of
measurement and instrumentation
- towards the understandings of a ‘working’ scientist,
who may use data gathering technologies that require theoretical interpretation
(for example, DNA ‘fingerprinting’).
Cause/effect
- The science student investigates discrete, single instances
of cause/effect, and
- through school science, develops increasing ability
to identify and control relevant variables
- towards the understandings of a ‘working’ scientist,
whose investigations take systematic account of interactions between multiple
variables.
Critique
- The science student is beginning to differentiate between
‘what’ is thought and ‘why’ it is thought, and
- through school science, develops increasing ability
to critique and justify their own and others’ reasoning
- towards the understandings of a ‘working’ scientist,
who takes part in robust debate and critique amongst a community of experts
before new theories are accepted and used.
Explanations
- The science student accepts personally plausible explanations
(recognises when evidence confirms their own ideas), and
- through school science, develops a beginning recognition
that more than one explanation may account for data/evidence
- towards the understandings of a ‘working’ scientist,
who attempts to clearly differentiate theory from evidence whilst considering
all possible explanations.
The nature of investigations
- The science student sees investigations as separate
episodes, and
- through school science, develops a gradual ability
to link chains of related investigations, in order to look for patterns
- towards the understandings of a ‘working’ scientist,
whose investigations are complex webs of inter-related episodes using
different methods, and seeking different types of evidence, to address
a question.
