Education research: content
Research by Nuthall shows half (and perhaps more) of all material taught in any class is already known by the students.

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.
• 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?
Hmm… an inquiry
approach!

18
The Science as a Human Endeavour strand
Two sub-strandsNature 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?
19
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.
20
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.
21
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.
22
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.
23
Inquiry-based curriculum
The Australian Curriculum: Science emphasises inquiry-based teaching and learning
Opportunities for student-led open inquiry should be provided within each phase of schooling
Teacher -driveninquiry
Student -driven inquiry
Semi -structured
inquiryLevel 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
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
24
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
25
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)
26

27
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
28
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.
29
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.

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.
31
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
32
Driver education – links to the Science Understanding strand
Sub-strand Science understanding
Biological science
Multicellular organisms rely on coordinated and interdependentinternal systems to respond to changes to their environment
Chemical science
• Chemical reactions, including combustion and the reactions ofacids, are important in both nonliving and living systems and involveenergy transfer• Different types of chemical reactions are used to produce a range ofproducts and can occur at different rates
Earth and space sciences
Global systems, including the carbon cycle, rely on interactionsinvolving the biosphere, lithosphere, hydrosphere and atmosphere
Physical science
• Energy conservation in a system can be explained by describingenergy transfers and transformations• The motion of objects can be described and predicted using thelaws of physics
33
Driver education – Links to the Science as a Human Endeavour strand
Sub-strand: Nature and development of scienceAdvances 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
34
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 relationshipsbetween variables and identifying inconsistencies
Evaluating Critically analyse the validity of information in secondary sourcesand 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
35
Linking science to literacy and numeracy
Bellarine, Great Ocean Road off-limits
Wind farms bannedThe 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.
The Surfcoast Times, 2 September 2011
Risks?
Benefits?
What do I think?What
does the community think?
How can I decide what to do?
Who should decide?
36
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.
