Multi-camera on-site video technology and post-lesson video stimulated interviews were used in a purposefully inclusive research design to generate a complex data set amenable to parallel analyses from several complementary theoretical perspectives. The symposium reports the results of parallel analyses employing positioning theory, systemic functional linguistics, distributed cognition and representational analysis of the same nine-lesson sequence in a single science classroom during the teaching of a single topic: States of Matter. Without contesting the coherence and value of a well-constructed mono-theoretic research study, the argument is made that all such studies present an inevitably partial account of a setting as complex as the science classroom: privileging some aspects and ignoring others. In this symposium, the first presentation examined the rationale for multi-theoretic research designs, highlighting the dangers of the circular amplification of those constructs predetermined by the choice of theory and outlining the intended benefits of multi-theoretic designs that offer less partial accounts of classroom practice. The second and third presentations reported the results of analyses of the same lesson sequence on the topic “states of matter” using the analytical perspectives of positioning theory and systemic functional linguistics. The final presentation reported the comparative analysis of student learning of density over the same three lessons from distributed cognition and representational perspectives. The research design promoted a form of reciprocal interrogation, where the analyses provided insights into classroom practice and the comparison of the analyses facilitated the reflexive interrogation of the selected theories, while also optimally anticipating the subsequent synthesis of the interpretive accounts generated by each analysis of the same setting for the purpose of informing instructional advocacy.

In this paper we examine Shulman’s notion of signature pedagogies for its usefulness extended to school science. We argue that school science is in an important sense an apprenticeship, and that calls for reform in school science are compatible with Shulman’s practice-based vision of professional learning. Two case studies of teaching and learning will be presented based on research in primary and secondary schools that involved working closely with teachers to develop and validate involving a representation-intensive pedagogy that lays claim to bringing school science closer to the knowledge building practices of science. Video images of classrooms, interviews with students and teachers, and documentation of students’ work, were used to construct insights into the teaching and learning process. It is argued that Shulman’s notion of professional practice as involving apprenticeships of knowledge, practice and identity provides a useful lens through which to view this innovation. Shulman’s characterisation of signature pedagogy is used to identify key features of the approach.

The Australian Science Curriculum has appeared at a time when there is widespread concern for the quality of science teaching and learning in Australia and the engagement of students in learning science, leading to calls for significant reform. The new curriculum thus carries the hopes of reform-minded scientists and educators for a change in the way science in schools can support teaching practices that engage students in quality learning. This analysis will examine whether it is an adequate vehicle for doing this. Will it live up to our expectations?

Having an appreciation for the subject, their students and what the subject can offer their students has both cognitive and emotional dimensions for teachers. This paper uses empirical data to explore the efficacy of a Deweyan inspired framework called “Aesthetic Understanding” to scrutinise relationships between teacher knowledge, identity and passion. The paper uses case study data of three teachers of maths and/or science generated from a video study to illustrate the relationships between the three elements of Aesthetic Understanding. The need to value the aesthetic dimensions of teaching when examining the subject-specific nature of secondary teaching is discussed.

 In chemistry education, students not only learn chemical knowledge and skills, but about the culture of chemistry – how scientists think about, and practise, chemistry. Students often learn that science is practised according to the “scientific method”, which is a model of scientific discovery, expounded by science historians and philosophers. The idealised “scientific method” has a number of steps: the collection of information about a phenomenon; the development of a hypothesis to explain those observations; an experiment to test a prediction that arises from the hypothesis, perhaps including more observations and collection of more information; improvement of the hypothesis; and so on.

The problem is that students (and even some science professionals) often do not understand the philosophy behind the scientific method and paradoxically, the scientific method does not seem to apply to most careers in science. The true nature of science is that concepts have been developed though variants of the “scientific method”, and that a process of testing the predictive value of these concepts has lead to advances in that conceptual knowledge. Hence the “scientific method” applies to the development of scientific ideas, not necessarily to the work of all scientists. It is not whether we personally use the scientific method in our day-today work, but how we use, apply, think about and communicate scientific knowledge and skills that makes us chemists.

Final report of the the Advancing Science by Enhancing Learning in the Laboratory (ASELL) project. 

Most researchers agree that the laboratory experience ranks as a significant factor that influences students’ attitudes to their science courses. Consequently, good laboratory programs should play a major role in influencing student learning and performance. The laboratory program can be pivotal in defining a student's experience in the sciences, and if done poorly, can be a major contributing factor in causing disengagement from the subject area. The challenge remains to provide students with laboratory activities that are relevant, engaging and offer effective learning opportunities.

The Advancing Science by Enhancing Learning in the Laboratory (ASELL) project has developed over the last 10 years with the aim of improving the quality of learning in undergraduate laboratories, providing a validated means of evaluating and improving the laboratory experience of students, and effective professional development for academic staff. After successful development in chemistry and trials using the developed principles in physics and biology, the project, with ALTC funding, has now expanded to include those disciplines.

The launching pad for ASELL was a multidisciplinary workshop held in Adelaide in April, 2010. This workshop involved 100 academics and students, plus 13 Deans of Science (or delegates), covering the three enabling sciences of biology, chemistry and physics. Thirty-nine undergraduate experiments were trialled over the three days of the workshop. More importantly, professional development in laboratory education was developed in the 42 academic staff that attended the workshop.

Following the workshop, delegates continued to evaluate, develop and improve both individual experiments and whole laboratory programs in their home institutions, mentored by the ASELL Team. Some highlights include:
- more than 15,000 student surveys carried out by delegates during 2010/11
- 10 whole lab programs were surveyed by delegates
- 4 new ASELL-style workshops, conducted by ASELL-trained delegates were run in 2010/11
- more than 100 ASELL-tested experiments available on the website (www.asell.org)
- ASELL workshops conducted in Philippines, Ireland in 2010, and planned in the USA and Thailand for 2011
- significant improvement in student evaluation of whole laboratory programs and individual experiments measured in universities using the ASELL approach
- high profile of ASELL activities in the Australian Council of Deans of Science (ACDS)
- research project on the misconceptions of academic staff about laboratory learning completed
- significant research on student learning in the laboratory, and staff perceptions of student learning have been carried out during 2010/11
- research results have been benchmarked against staff and students in the USA.

The biggest unresolved issue for ASELL is one of sustainability in the post-ALTC funding era. ASELL will make a series of recommendations to the ACDS, but the future of the program depends, to a large part, on how the ACDS responds.

Final report of the the Active Learning in University Science (ALIUS) project.

This project aims to establish a new direction in first year chemistry teaching – away from didactic teaching methods in large lecture style teaching to more active, student centred learning experiences. Initially six universities have been involved in practice-based innovation: Charles Sturt University (NSW), The University of Sydney (NSW), Curtin University of Technology (WA), The University of Adelaide (SA), Deakin University (Vic), University of Tasmania (Tas).

Three domains have been identified as the architecture upon which sustainable L&T innovation will be built. These domains include Learning and Teaching innovation in project leaders’ and colleagues’ classrooms, development of project leaders as Science Learning Leaders, and creation of a Science Learning Hub to serve as a locus and catalyst for the development of a science teaching community of practice.

Progress against specified outcomes and deliverables

Learning and Teaching Innovation

The purpose of this domain is to improve student learning, engagement, retention and performance in large chemistry classes through increased use of student-centred teaching practice.
• The Project is named: ALIUS (Active Learning in University Science) - Leading Change in Australian Science Teaching
• All six ALIUS universities have now implemented Teaching Innovation into ALIUS team member classrooms
• Chemistry colleagues at three ALIUS universities have now implemented Teaching Innovation into their classrooms
• The ALIUS member in physics has implemented Teaching Innovations into his classrooms
• Chemistry colleagues at three ALIUS institutions have tried some Teaching Innovations in their classrooms
• Non-chemistry colleagues at four ALIUS institutions have tried, or expressed an interest in trying, Teaching Innovations in their classrooms
• The POGIL method has proved to be a useful model for Teaching Innovation in the classroom
• Many classroom resources have been developed and used at several ALIUS institutions; some of these have been submitted to the ALIUS database for public access. The remainder will continue to submitted
• Two seminars about Teaching Innovation have been developed, critiqued, revised, and presented at five ALIUS universities and three non-ALIUS universities
• Particular issues associated with implementing Teaching Innovations in Australian classrooms have been identified and possible solutions developed
• ALIUS members have worked with Learning and Teaching Centres at their universities to share methods.

Developing Science Learning Leaders

The purpose of this domain is to develop leadership capacity in the project leaders to equip them with skills to lead change first at their institutions, followed by developing leaders and leading change at other local institutions
• ALIUS members participated in Leadership Professional Development sessions with Craig McInnis and Colin Mason; both these sessions were found to be valuable and provide context and direction for the members and the ALIUS team
• The passion of an ‘early adopter’ was found to be a significant element in each node of the distributed framework
• Members developed an awareness of the necessity to build both the ‘sense of urgency’ and the ‘guiding coalition’ at each node
• ALIUS found the success of the distributed framework is strongly influenced by the relational aspects of the team.

Create a Science Learning Hub

The online Hub serves as a local and national clearinghouse for development of institutional Learning Leaders and dissemination of L&T innovation.
• The ALIUS website is now active and being populated with resources
• The sharing resource database structure is finalised and being populated with contributed materials.

Lessons Learnt

In order to bring about change in teaching practice it is necessary to:
• demonstrate a convincing benefit to student learning
• show that beyond an initial input of effort classroom innovations will not take more time than what is now done
• maintain a prominent exposure among colleagues - repeatedly give seminars, workshops, and everyday conversations; talk about teaching innovation; talk about easy tools to use; invite people to your classroom; engage colleagues in regular peer review of classroom practice
• have support from people already present in leadership roles to lead change in teaching practice
• have a project leader, someone for whom the project is paramount and will push it forward
• find a project manager, even with money budgeted
• meet face-to-face.

Dissemination
• Seminars presented 19 times including over 400 individuals and more than 24 Australian universities
• Workshops presented 25 times, over 80 participants at 11 Australian and two New Zealand Universities
• Two articles published in Chemistry in Australia, the Australian Chemistry Industry Journal of the Royal Australian Chemical Institute
• One refereed paper published in the Journal of Learning Design.

Why do people become teachers? Some of the reasons for entering science and mathematics teaching include: wanting to make a difference, good job conditions, liking young people, loving science and maths, being good at teaching, having had a good maths/science teacher, a shortage of teachers, and a love of learning.

We need good teachers, and especially teachers with good science and chemistry backgrounds. It is also true of all school levels, including primary. Job satisfaction and the joy of teaching are not enough. Everyone needs encouragement, acknowledgement and respect. Everyone needs to know that they and their work are valued. Teachers need these too. It is a good investment in the nation’s future.

The prestigious BHP Billiton Science Teacher Awards are awarded annually to one teacher from each state of Australia. The awards recognise and value the time and effort that teachers give to the profession and to students conducting scientific research projects. This paper examines the Science Award scheme to identify the characteristics common to these innovative teachers in science. The data is drawn from interviews with seven award-winning teachers plus the judges of the scheme. The data indicated that quality teaching was evident in their practice - valuing students’ ownership of their work, doing authentic science investigations and showcasing their work.
