Education research: content
Research by Nuthall shows half (and
perhaps more) of all material taught in
any class is already known by
the students.
Nuthall (2005), The cultural myths and realities of classroom teaching and learning: a personal
journey?, in Teachers College Record, 107 (5), 902-903.

Assessment
“ … the fundamental purpose of assessment
is to establish where learners are in their
learning at the time of assessment.”

Science research: The ROSE Project
The Relevance of Science Education (ROSE) project surveyed students from many
countries.
Findings include:
• The more developed a country, the less positive the view of science by students
• In the UK, 14-to 15-year-old students were surveyed:
– 11% agreed with ‘I like school science better than other subjects’
– 8% agreed with ‘I would like to become a scientist’
• These figures are consistent with studies in Australia (for example, PISA results)

A research base for Australian Curriculum: Science
The framing paper for the Australian Curriculum:
Science draws on two particular research reports
which synthesise national and international research
on school science education:
• Australian School Science Education National
Action Plan 2008-2012 (Goodrum & Rennie, 2007)
• Re-imagining Science Education: Engaging
students in science for Australia’s future (Tytler,
2007)

Research: Fensham
A study of Beijing’s heads of the top 11 science
research institutions to determine desirable qualities
for their scientists, beyond knowledge, listed the
following:
Rank
Desired quality
Most important
Creativity
Very important
Personal interest in science; perseverance; willingness
and desire to inquire
Important
Ability to communicate; social concern; team spirit
Fensham P (2004). Engagement with science: An international issue that goes
beyond knowledge. Paper presented at the SMEC Conference.

Urban legends and investigable questions
‘Science is a dynamic, forward-looking, collaborative
human endeavour arising from our curiosity and interest.’
From the Shape of the Australian Curriculum: Science paper, May 2009.
Hmm… an
inquiry
approach!
• Can the unaided human
voice shatter glass?
• Can diving underwater
protect a person from
gunfire?
• Is grass still green at night?
Sport … music …
updating Facebook
profiles … latest diet
fads … catching up
with friends at the
weekend … pets …
Science?

17
The Science as a Human Endeavour strand
Two sub-strands
Nature and development of science
• How do scientific ideas develop?
Use and influence of science
• How is science used in work and leisure?
• How do science and technology affect our
environment and our lives?
• What is the scope of science-related careers?
18
Revised standards: Level 7 and 8 biological science
• Science Understanding (SU):
They analyse the relationship between structure and function at
cell, organ and body system levels. They use dichotomous keys to
identify and classify living things. They explain how living organisms
can be classified into major taxonomic groups based on observable
similarities and differences. They predict the effect of
environmental changes on feeding relationships.
• Science as a Human Endeavour (SHE):
They discuss how science knowledge can be applied to generate
solutions to contemporary problems and explain how these
solutions may impact on society.
19
Revised standards: Level 9 and 10 biological science
• ACARA achievement standard:
They explain the processes that underpin
heredity ...
• AusVELS strengthened achievement
standard:
They explain the role of DNA and genes in cell
division and genetic inheritance.
20
Revised standards: Level 9 and 10 chemical science
• ACARA achievement standard:
… students analyse how the periodic table organises
elements and use it to make predictions about the
properties of elements.
• AusVELS strengthened achievement standard:
They explain how similarities in the chemical behaviour of
elements and their compounds and their atomic structures
are represented in the way the periodic table has been
constructed. They compare the properties of a range of
elements representative of the major groups and periods
in the periodic table.
21
Revised standards: Level 9 and 10 physical science
• ACARA achievement standard:
They apply relationships between force, mass
and acceleration to predict changes in the
motion of objects.
• AusVELS strengthened achievement standard:
They give both qualitative and quantitative
explanations of the relationships between
distance, speed, acceleration, mass and force to
predict and explain motion.
22
Inquiry-based curriculum
The Australian Curriculum: Science emphasises inquiry-based
teaching and learning
Level 5-6:
With guidance,
select
appropriate
investigation
methods to
answer
questions or
solve problems
… decide which
variable should
be changed and
measured in fair
tests
Teacher driven
inquiry
Semi structured
inquiry
Student driven
inquiry
Opportunities for student-led open inquiry should be provided
within each phase of schooling
Level 7-8:
Collaboratively and individually plan
and conduct a range of investigation
types … in fair tests, measure and
control variables, and select
equipment to collect data with
accuracy appropriate to the task
Level 9-10:
Formulate questions or
hypotheses that can be
investigated scientifically … plan,
select and use appropriate
investigation methods… select
and use appropriate equipment
23
A model for examining ideas about inquiry
1. Level of integration of skills and domain knowledge:
• Skills taught as separate unit ‘the scientific method’
• Science skills used to reinforce application of knowledge
• Content and skills integrated through the unit
• Context provided for content and skill integration
2. Level of student direction or choice/level of scaffolding needed:
Prescribed processes  independent task
• Focus on reasoning ability
• Focus on identifying variables
• Assessing evidence and developing understanding
• Report writing
24
Assessment of inquiry
• Assessment of students’ learning should
include measures of inquiry expertise
• Consider the sub-strands of the Science
Inquiry Skills (SIS) strand
• Importance of listening to students’ ideas as a
measure of learning
• Role of student self-evaluation (e.g. SOLO
taxonomy for assisting students identify the
complexity of their thinking)

SOLO taxonomy
Structure of the Observed Learning Outcome (SOLO)
• first described by John Biggs and Kevin Collis in
Evaluating the Quality of Learning: The SOLO
Taxonomy, New York Academic press, 1982
• enables assessment of student work in terms of
quality rather than how many bits of this and that a
student described correctly
27
SOLO taxonomy levels
SOLO is divided into a number of levels of learning:
• Prestructural where a child needs support in expressing an
idea on the topic.
• Unistructural where a child can express one relevant idea.
• Multistructural where the child can express a number of
relevant ideas e.g. defines, describes.
• Relational where a child makes connections and
links between these ideas e.g. compares & contrasts,
analyses.
• Extended abstract where a child thinks beyond the subject or
takes the learning into a new context e.g. generalises,
hypothesises.

Scenarios for inquiry: Stinking fish
Hundreds of stinking dead fish dumped at
Portarlington jetty have angered local
fishermen.
Surfcoast Times, 2 September 2011
Newspaper articles can be edited so that
students may be encouraged to generate
questions/propose possible
explanations/suggest methods of inquiry
which involve collection of primary and
secondary data/ differentiate between
investigable and non-investigable
questions.
29
Planning assessment: a sunscreen pill
British scientists, inspired
by samples of coral taken
from the Great Barrier
Reef, hope to produce a
sunscreen in a pill that
gives weeks of protection
after working out how
coral shields itself from the
harmful ultraviolet rays in
sunshine. The pill could be
tested on people in 5
years.
30
Themed units of work: integration of sub-strands
Opportunities for delivering science curriculum:
• Themed units of work, e.g. driver education
• Outside-class activities: e.g. school camps:
ecosystems; astronomy; biology; water quality
• Other school subjects: e.g. plate tectonics studied in
Geography
• School activities: e.g. guest speakers at school
assemblies, linking “jeans for genes day” to a study
of genetics
31
Driver education – links to the Science Understanding strand
Sub-strand
Science understanding
Biological
science
Multicellular organisms rely on coordinated and interdependent
internal systems to respond to changes to their environment
Chemical
science
• Chemical reactions, including combustion and the reactions of
acids, are important in both nonliving and living systems and involve
energy transfer
• Different types of chemical reactions are used to produce a range of
products and can occur at different rates
Earth and
space
sciences
Global systems, including the carbon cycle, rely on interactions
involving the biosphere, lithosphere, hydrosphere and atmosphere
Physical
science
• Energy conservation in a system can be explained by describing
energy transfers and transformations
• The motion of objects can be described and predicted using the
laws of physics
32
Driver education – Links to the Science as a Human Endeavour strand
Sub-strand: Nature and development of science
Advances in scientific understanding often rely on developments
in technology and technological advances are often linked to
scientific discoveries
Sub-strand: Use and influence of science
• People can use scientific knowledge to evaluate whether they
should accept claims, explanations or predictions
• Advances in science and emerging sciences and technologies
can significantly affect people’s lives, including generating new
career opportunities
33
Driver education– links to the Science Inquiry Skills strand
Sub-strand
Science Inquiry Skills
Questioning and
predicting
Formulate questions or hypotheses that can be investigated scientifically
Planning and
conducting
Plan, select and use appropriate investigation methods, including field
work and laboratory experimentation, to collect reliable data; assess risk
and address ethical issues associated with these methods
Processing and
analysing data and
information
Analyse patterns and trends in data, including describing relationships
between variables and identifying inconsistencies
Evaluating
Critically analyse the validity of information in secondary sources
and evaluate the approaches used to solve problems
Communicating
Communicate scientific ideas and information for a particular purpose,
including constructing evidence-based arguments and using appropriate
scientific language, conventions and representations
34

Bellarine, Great Ocean Road off-limits
Wind farms banned
The Bellarine Peninsula and Great Ocean Road
have been made no-go zones for wind farms under
extensive new planning rules.
In addition, developments will be blocked if they
are within 5km of a major regional centre or within
2km of an existing dwelling unless the owner gives
written consent.

Planning assessment: ‘wicked problems’
• Socio-scientific investigations involve a complexity (and hence the term
‘wicked problem’) which often make them difficult to utilise in the classroom.
However, if students are to be taught how evidence is developed and used in
science in authentic settings, this issue requires addressing.
• A solution: case studies may provide data from real situations, or simulated,
to allow students to explore questions that might be posed, or which they
generate themselves, through representations of the data and analysis.
Example:
A data bank was made electronically available to students from an Antarctic
expedition concerning body weight, breeding patterns and mortality of
mutton birds. Students could then pose questions, construct hypotheses,
make predictions and construct data sets to explore these.
