<strong>August</strong> 20<strong>13</strong><br />

From the President<br />

During the last school holidays I<br />

attended CONASTA 62 (the national<br />

science teachers’ conference) at<br />

La Trobe University. The speakers<br />

and presenters were in my opinion<br />

excellent and I was particularly<br />

impressed by Barry Jones, maybe all<br />

the more because I can’t reme<strong>mb</strong>er<br />

having heard him speak before. Peter<br />

Turnbull and his organising committee<br />

are now working to finalise the<br />

speakers and presenters for CONASTA<br />

63 which will be held in Adelaide next July. This event only<br />

comes to <strong>South</strong> Australia every eight years and will be our main<br />

conference focus for 2014 and therefore we will not be holding<br />

our usual <strong>SASTA</strong> two day conference in April.<br />

TRB<br />

From this year on all teachers in <strong>South</strong> Australia wishing to renew<br />

their teaching registration for a further term, will be required<br />

to undertake 60 hours of professional learning within their 3<br />

year term of registration referenced to the <strong>Australian</strong> National<br />

Professional standards for teachers. <strong>SASTA</strong> is ensuring that all of<br />

the professional learning that we offer meets these requirements.<br />

Also if you book any workshop or conference online with our<br />

website, a record is kept on our database that you are able to<br />

access in 3 years’ time if you need to provide evidence to the<br />

Teachers Registration Board.<br />

Organic Water<br />

I notice with great interest, that in the last month, the ACCC has<br />

taken action to have manufacturers remove the word “organic”<br />

from 7 different brands of bottled water. Over the past 5 years<br />

I have been collecting different examples of bottled “organic”<br />

water for use in the science classroom as a discussion point for<br />

students. A government body has finally decided that there is no<br />

sensible reason for labelling bottled drinking water “organic”.<br />

I will now wait and see if the ACCC takes action against the<br />

shopping mall purveyors of water “magnetisers” and the selling<br />

of “magnetic water” as a panacea.<br />

<strong>SASTA</strong> is offering a full day of workshops for all teachers of<br />

Science from Reception to Year 12 who are in the first 3 years of<br />

teaching.<br />

All sessions will be interactive and provide fun learning<br />

opportunities as well as resources that will enrich and inform your<br />

science teaching. Five main sessions will run throughout the day<br />

each with a different focus:<br />

• The <strong>Australian</strong> Curriculum: Science – an overview of the<br />

curriculum, planning tools and strategies<br />

• Assessment – task design and implementation<br />

• Pedagogy – science investigations, inquiry learning,<br />

engaging students in science<br />

• Resources – ICT and other resources for the science<br />

classroom<br />

• Behaviour Management – successful classroom strategies<br />

In addition, there will be exciting science demonstrations and a<br />

chance to interact with the presenters.<br />

This hands-on interactive professional learning day will cater<br />

specifically for each level of schooling. Workshops will be offered<br />

concurrently at each session so participants can choose to attend<br />

those that are most relevant to their area of teaching: Early<br />

Years, Primary Years, Middle Years or Senior Years.<br />

National Professional Standards for Teachers:<br />

Teachers will receive a certificate of attendance that details the<br />

hours of professional learning and the Standards covered: 2.1,<br />

Teachers Professional Learning<br />

In Term 3 <strong>SASTA</strong> will offer the following professional learning opportunities:<br />

For Secondary/Middle school teachers:<br />

1. Working with the Achievement Standards:<br />

Assessment that drives learning in science.<br />

Date: Friday 23rd <strong>August</strong><br />

Time: 9.00 am - 3.00 pm<br />

Venue: Education Development Centre, Milner Street,<br />

Hindmarsh<br />

Cost: Personal Me<strong>mb</strong>ers $95, Corporate Me<strong>mb</strong>ers $120,<br />

Non-me<strong>mb</strong>ers $150<br />

Lunch and morning tea provided. Register at www.sasta.asn.au<br />

Viewed through the lens of assessment, what has ACARA given<br />

us so far?<br />

• Content<br />

• Achievement Standards<br />

• Exemplars of three different levels of achievement<br />

What ACARA has not done is to describe the quality of<br />

achievement.<br />

In this workshop we will explore assessment for, as and of<br />

learning. Will look at assessment design and use exemplars to<br />

develop skills in designing assessment tasks that drive learning.<br />

We will also explore how to use the Achievement Standards<br />

to make on-balance judgments about the quality of learning<br />

demonstrated by the students. We will describe this achievement<br />

across an A-E continuum using an assessment rubric and look<br />

at how such an assessment tool can be used to assist teachers to<br />

plan rich units of work that allow for access as well as excellence.<br />

The Workshop will cover the following:<br />

• Assessment Principles, Purposes and Features<br />

• Assessment in The <strong>Australian</strong> Curriculum<br />

• Achievement Standards<br />

• Assessment Literacy<br />

• An Assessment Tool<br />

• Quality Assessment tasks<br />

• Reporting<br />

2. Inquiry- based learning; how it works in the<br />

science classroom.<br />

Date: Friday 1st Nove<strong>mb</strong>er<br />

Time: 9.00 am - 3.00 pm<br />

Venue: Education Development Centre, Milner Street,<br />

Hindmarsh<br />

Non me<strong>mb</strong>ers $150<br />

Lunch and morning tea provided. Register at www.sasta.asn.au<br />

The <strong>Australian</strong> Curriculum: Science emphasises inquiry-based<br />

teaching and learning. Scientific inquiry promotes critical and<br />

creative thinking by encouraging flexibility and open-mindedness<br />

as students speculate about their observations of the world. In<br />

an inquiry classroom, students are able to challenge themselves<br />

to identify questions and draw evidence-based conclusions using<br />

scientific methods.<br />

In this workshop teachers will investigate the process and<br />

practicalities of inquiry learning in the Science classroom.<br />

They will engage in hands-on activities that will inform their<br />

understanding of the types of inquiry and how to implement<br />

them in their teaching program.<br />

The Workshop will cover the following:<br />

• What is Science? How do scientists work?<br />

• What is Inquiry Based Teaching?<br />

• Forms of Inquiry<br />

• Practical Representation/The 5Es Model<br />

• Strategies for Inquiry Based Teaching<br />

• Adapting materials<br />

• Leading change<br />

This workshop will support teachers to further develop their<br />

current understanding of the Science Understanding Strand:<br />

Earth and Space Science<br />

The workshop aims to build teacher knowledge and conceptual<br />

understandings while participants are actively engaged in science<br />

investigations using the Science Inquiry Skills. The workshop will<br />

use an inquiry approach to the learning of science, providing<br />

teachers with the confidence and resources to implement the<br />

requirements of the <strong>Australian</strong> Curriculum in their classrooms.<br />

Structure of Workshops<br />

• Big Science Ideas – mapping of the concepts explored in the<br />

sub strand, what is your part in the story?<br />

• Building Understanding – hands- on investigations<br />

that allow participants to explore the concepts and build<br />

understanding using explicit and modelled pedagogy.<br />

• Unit Development – opportunity to develop rich science<br />

programs that e<strong>mb</strong>ed the Capabilities of Literacy and Critical<br />

and Creative Thinking, the Science Inquiry Skills and that are<br />

framed by the Science as a Human Endeavour sub strand.<br />

Children need opportunities to develop practical and inquiry skills<br />

in order to engage with the world in a scientific way and to make<br />

sense of what they are learning Hands-on investigations promote<br />

curiosity and engagement and provide opportunities for the type<br />

of discussion and questioning which develop understanding.<br />

This workshop will look at science investigations in action.<br />

Teachers will be led through the elements of a scientific<br />

investigation by:<br />

• Posing questions that are scientifically investigatable<br />

• Giving priority to evidence - gathering scientific data by<br />

recording observations and making measurements.<br />

• Formulating explanations from evidence to address the<br />

question.<br />

• Evaluating their explanations in light of scientific<br />

understanding.<br />

• Communicating and justifying their proposed explanations.<br />

Teachers will develop an understanding of how to use an<br />

investigation planner and implement the elements of scientific<br />

investigation in their classrooms.<br />

Who should attend: Primary Years teachers<br />

Please Note:<br />

Although this course is not designed specifically for teachers who<br />

have used Primary Connections, these workshops will provide<br />

a natural progression to those units of work and continue to<br />

deepen science understanding.<br />

Who should attend: Year 6/7 teachers or specialist<br />

science teachers<br />

Echidnas reveal evolution of e<strong>mb</strong>ryo growth<br />

One of the distinctive features of mammals is the prolonged<br />

development of the e<strong>mb</strong>ryo in the mother’s wo<strong>mb</strong>. Evolutionary<br />

biologists have long been fascinated by this massive energy<br />

investment by mammalian mothers, and because of this<br />

disproportionate energy input, believe that there is a rivalry in<br />

the e<strong>mb</strong>ryo between genes inherited from the father and the<br />

mother that control the e<strong>mb</strong>ryo’s energy supply. It is thought<br />

that the father’s genes may promote growth for the increased<br />

viability of his offspring, while the mother’s genes restrict<br />

growth to conserve her energy for future offspring. There are<br />

a nu<strong>mb</strong>er of mammalian genes whose activity depends on<br />

whether it is inherited from the father or the mother. This genetic<br />

phenomenon is called genomic imprinting.<br />

<strong>Australian</strong> platypuses and echidnas have provided valuable clues<br />

towards our understanding of this genetic parental conflict.<br />

Unlike placental mammals, these monotremes lay eggs, but still<br />

have a short 2-3 week pregnancy and a simple placenta, and<br />

therefore can be considered as a midway point in mammalian<br />

evolution. As the mother’s main energy investment is the<br />

production of a large nutrient-packed egg before fertilisation the<br />

parental conflict is believed not to exist in monotremes.<br />

A recent study involving researchers from the University of<br />

Adelaide unravelled a key step that may have initiated the<br />

parental conflict and genomic imprinting of a pair of known<br />

growth-related genes. The imprinted genes IGF2 and IGF2R code<br />

for the growth promoter insulin-like growth factor 2 (IGF2) and<br />

its inhibitor, the IGF2 receptor (IGF2R). The binding of these two<br />

proteins to each other regulates growth before and after birth.<br />

In marsupial and placental mammals the IGF2 gene is active<br />

when inherited from the father and the IGF2R is active from the<br />

mother’s copy of the gene. A unique element was identified in<br />

the echidna IGF2R gene sequence that promoted a change in the<br />

IGF2R protein, triggering the binding of the two proteins. This<br />

is thought to be the crucial first step that set off a competition<br />

growth. The IGF2R protein structures from echidna, opossum,<br />

human and chicken were compared. A gradual gain in the<br />

ability to bind IGF2 was revealed from monotremes to placental<br />

mammals. This is a great example how evolution step by step<br />

leads to the fine-tuning of molecules and gene regulation driving<br />

e<strong>mb</strong>ryonic development.<br />

This research was is an international collaboration involving<br />

structural biologists, biochemists and geneticists from the<br />

Universities of Bristol, Oxford, Adelaide, the University College<br />

of Dublin and the Michael Smith Genome Sciences Centre,<br />

Vancouver. See the paper below for a full list of collaborators.<br />
