This paper reports the results from a pilot trial where pre-service primary teachers' views of science were deliberately challenged through weekly perturbing statements and associated readings within a science methods course. This explicit reflective approach to nature of science aimed to encourage the pre-service teachers to critically examine their prior beliefs, values and practices of teaching and learning science. The theoretical basis of this research was based upon a framework of facilitated reflection that included opportunity for reflection, expectations regarding the quality of reflection, and scaffolding to support the development of reflection as a skill. As a consequence of this explicit reflection, 89% of pre-service teachers believed they had grown as teachers of science, 83% believed their attitudes and/or beliefs about science teaching and learning had been challenged, and 94% believed they had grown as reflective practitioner. Common themes identified for pre-service teachers' perceptions of change were challenging existing views, analysing practice, development of critical thinking skills, and reflecting on future science teaching. Examples of documents used to challenge views of science will be available for discussion.
There were giant green footprints leading into the workshop room. The sign on the door stated boldly "OGRE, BEWARE!" As we walked through the door we were transported into Shrek's swamp. The tutor greeted the students by stating that she had found a strange green substance in the swamp, and needed their help to identify what it was. Each group of students was presented with an ice-cream container half full of the strange substance. [The substance being investigated was called 'oobleck' and consisted of cornflour, water and green food colouring. Oobleck is classified as slime, and behaves both as a solid and a liquid.] The students were informed that they had to investigate this substance by using all our senses, as well as describing how the substance moved. Then they had to decide what it might be. There was a lot of discussion and laughing within the groups as they set about exploring the unusual substance. One group came up with some great descriptions, such as green, icky, oozy, slimy, alien's blood, squishy, smooth, runny, and shiny. The class then shared their ideas. There were even better descriptions used by the class. Such as tacky, pasty, rubbery, green icing sugar, a green marshmallow that you have sucked on and spat out, snot (oh gross!!), wet and dry at the same time, and lazy playdough. The class then had to draw a picture of the substance and write some words around the picture to describe it. They were encouraged to colour the picture. Some students used green highlighters while others used green pencils. Other students decided to put eyes on their picture to make it come alive, stating that it moved as if it was alive.This short vignette, which summarises a real workshop from a science methods course, illustrates various unique and challenging characteristics which pre-service primary teacher bring to their teacher education course. One of these characteristics is a limited understanding of what science is, known as 'nature of science'. Many pre-service primary teachers perceive science as a fixed body of knowledge, totally objective, uncreative and unimaginative, and driven solely by the scientific method (Appleton, 2006). Further, they do not recognise the everyday nature of science, or the changing nature of science (Olson & Appleton, 2006). The inability of these pre-service teachers to recognise the science component of the workshop, that they themselves were working as scientists, the place of creativity and imagination within the workshop, and that all answers provided were correct, highlighted their narrow views of science.
After this workshop, one student commented, "This isn't science, this is literacy!" A second student agreed, and asked the tutor why they were doing a literacy activity in a science workshop.
This paper presents the results from a pilot trial where explicit reflection, in the form of weekly perturbing statements and associated readings, was used to challenge pre-service primary teachers' views of science teaching and learning. The purpose of this research was to evaluate the effectiveness of such an approach in terms of the pre-service teachers' personal growth as a teacher of primary science, attitudes and beliefs about science teaching and learning being challenged, and personal growth as a reflective practitioner.
Teachers' beliefs and attitudes towards teaching science have been found to influence the amount and quality of science that is taught in the primary classroom. Teachers with negative beliefs and attitudes towards science tend to spend less time teaching it; are more likely to employ didactic approaches rather than student-centred approaches; place heavy reliance on kits, prescriptive textbooks and worksheets; and avoid all but the simplest hands-on work (Appleton & Kindt, 1999; Bencze & Hodson, 1999; Harlen & Holroyd, 1997).
Various authors have advocated a reflection orientation to primary science teacher education as a means of providing meaningful experiences to pre-service teachers that enable them to critically examine their prior beliefs in order to initiate transformation in their thinking and teaching practices (Abell & Bryan, 1997; Bryan & Abell, 1999; Skamp, 1995; Zembylas & Barker, 2002). This reflection orientation stems from the scholarship of Dewey (1993) and Schön (1987), and is grounded in the belief that pre-service teachers learn to teach science through a process of re-evaluating and reforming their existing theories when confronted with perturbing evidence. Pre-service teachers enter primary methods courses holding ideas, beliefs and values that form their personal theories about science teaching and learning (Abell & Bryan, 1997). The reflection orientation is characterised by asking pre-service teachers to describe their ideas, beliefs and values about science teaching and learning and then providing experiences that help to clarify, confront, and possibly change such personal theories. Beginning teachers of science require many opportunities to inquire into and think critically about science teaching and learning. The reflection orientation to science preparation takes into account that future teachers learn about science in a number of different contexts, each providing the opportunity for reflection and learning (Abell & Bryan, 1997).
Campoy (2000) described a framework of facilitated reflection within teacher education. This framework included opportunity for reflection, expectations regarding the quality of reflection, and scaffolding to support the development of reflection as a skill. Opportunity for reflection refers to the provision of many and various opportunities to reflect upon coursework and/or field experiences of teaching. Campoy (2000) claimed that while many researchers include a variety of activities to promote reflection about teaching practices (such as journals, classroom discussion, portfolios, analysing case studies, and videoed exemplary practice) they fail to include information on how to reflect. Expectation regarding the quality of reflection addresses the issue of what constitutes good and poor reflection, and the importance placed on supported opinion (Campoy, 2000). Campoy (2000) considered the use of a rubric to set standards for different levels of reflection, verbal and written feedback, modelling, and examples as effective means to address expectation. Scaffolding for reflection refers to course activities that support the development of reflective thinking through increasingly complex levels of reflection, such as metacognitive thinking (Campoy, 2000).
The framework of facilitated reflection was selected as the theoretical basis of the current research for three reasons. First, it allowed for transformative change by challenging the pre-service teachers' thinking (Kagan, 1992). Second, the framework offered an holistic means of implementing the reflection process for the teacher educator, while also providing detailed information on the expectations of the reflections for the pre-service teachers. Third, the framework encouraged a culture of reflection where both the teacher educator and the pre-service teachers could share, discuss and reflect upon certain learning experiences and the reflection process itself.
Views of nature of science are tied to pre-service teachers' beliefs about science teaching and learning. The 'naive' conceptions of nature of science held by most pre-service teachers leads to a belief in a didactic approach of science instruction, where science is presented as a body of static knowledge (Abell, Martini, & George, 2001). The techniques used during science instruction are also perceived as being static, requiring minimal or no justification (Bartholomew, Osborne, & Ratcliffe, 2004). Pre-service teachers perceive science as a process of discovering what is out there, rather than as a human process of inventing explanations to describe how the world works. Similarly, pre-service teachers see learning as a process of acquiring knowledge through discovery (Abell & Smith, 1994). Such approaches have an emphasis on the product, rather than the processes of science. Further, such approaches to science instruction, which teach about what we know, inhibit any discussion on nature of science, the tentativeness of scientific knowledge, or the social dimensions of science (Bartholomew et al., 2004).
Techniques to improve nature of science in pre-service teachers have centred around the use of scientific inquiry, and explicit instruction through reflection (Abd-El-Khalick, 2001; Abd-El-Khalick & Akerson, 2004; Gess-Newsome, 2002). As a consequence of an inquiry course, Gess-Newsome (2002) found preservice teachers' conceptions of science as primarily a body of knowledge (or product) changed to a more appropriate, blended view of science as a body of knowledge generated through the active application of scientific inquiry (process and product). Akerson, Abd-El-Khalick and Lederman (2000) found that an explicit reflective approach to nature of science instruction, within a science methods course, was effective in producing changes in elementary teachers' views of nature of science. Internalising the importance of teaching about nature of science was found to be essential for pre-service teachers to address nature of science instructionally. Lederman (1999) considered nature of science such an important instructional objective that it should be a component of every science teacher education instructional unit, lesson and activity.
Facilitated reflection was provided through opportunity, expectation and scaffolding. Opportunity to reflect was provided by weekly workshop discussions for each reflection. Within these discussions the pre-service teachers were constantly challenged as to why they believe the way they do, and where has that belief come from. This was supported by a detailed unit outline that described the purpose of the reflection assignment. Each reflection had questions to be used as discussion points in the workshops, along with questions to direct the pre-service teachers' individual reflections (see Table 1). Expectations regarding the quality of reflection were provided through a detailed rubric that provided information on what was required for each grade level. Expectation was also provided through formative assessment, where the first four reflections were handed in part way through the semester. Detailed feedback was provided on these reflections, highlighting what the pre-service teacher was doing well, what needed to be improved, and how the reflection could be improved. Scaffolding for reflection was addressed by encouraging higher order thinking through questioning. As the pre-service teachers participated in the weekly workshops they were questioned about the characteristics of the activities. For example, the activity described at the start of this paper is characterised by open-endedness, inclusiveness and simplicity. Comparing these characteristics to those associated with their science learning experiences from high school, and then questioning and justifying the approach taken, allowed the pre-service teachers to further develop their reflective skills.

They really forced me to think about some pretty key issues in relation to science teaching. [2006:A9]One predominant weakness was associated with the reflections: there were too many reflections to complete. Other minor weaknesses of the reflections included being repetitive, irrelevant, not allowing for individuality, and not relating to practical experiences (see Table 2). Three pre-service teachers did not state any weaknesses associated with the reflections.
Focussed reflection and discussion which enabled you to reflect on something you might not have thought of. [2006:A5]
Challenged misconceptions commonly held by primary teachers. [2006:A13]

Table 4 presents the common themes identified as reasons behind the pre-service teachers' perceptions of change. Comments from pre-service teachers to highlight these themes are presented below. The pre-service teachers believed that challenging their existing views assisted them to grow as a teacher of science, challenge their existing attitudes and/or beliefs about the teaching and learning of science, and grow as a reflective practitioner.
Forced me to think about things I would not have considered before. [2006:C3]Analysing practice assisted the pre-service teachers to grow as teachers of science, and to challenge their existing attitudes and/or beliefs about the teaching and learning of science.
Writing about what I think about science (eg. science is just for boys) challenged my thinking. [2006:D5]
Exploring the reflections increased my knowledge of strategies and concepts. [2006:C4]

The development of critical thinking skills was identified as the major theme to growing as a reflective practitioner.
They made me critically think about the topics and events and reflect on them. [2006:E6]Reflecting on their future teaching assisted the pre-service teachers to grow as teachers of science and as reflective practitioners.
Reflecting not only how you teach but also on the subject matter and the children themselves provides greater insight how to improve my own teaching. [2006:E8]
Reflecting on the activities and the facts, discussing what I would do as a future teacher helped me to make the connection between reflecting and improving. [2006:E5]
It has made me consider how I will teach in the future. [2006:C9]
The positive feedback from the pre-service teachers highlighted their growth within two areas: understanding science, and understanding the reflection process. Previous research that investigated methods of challenging nature of science had been interpreted solely from the science perspective (Abd-El-Khalick, 2001; Gess-Newsome, 2002). The results presented in this paper illustrate how challenging views, and the use of the reflection process, go hand-in-hand. The benefits of such an explicit reflective approach are thus doubled when both perspectives are addressed.
This pilot study has highlighted the effectiveness of using an explicit reflective approach when evaluated with an end of semester questionnaire. Additional information to support this assertion can be obtained from analysing the pre-service teachers' individual reflections, where supporting (or conflicting) statements are obtained to demonstrate challenged views of science and perhaps modified practice during field experience. Such an analysis forms the next phase of this research, where a larger sample and modifications to the reflections (as described below) will be used.
The explicit reflective approach to challenging views can be applied to any discipline, where students' prior beliefs and attitudes have to be explored, discussed and confronted. Perturbing statements and accompanying readings, cases, dilemmas, videos, or posters can be developed to fit the required discipline. Implicit in the reflective process is the ability of the teacher to share responsibility in the learning process (Bryan & Tippins, 2006). Teachers should model the reflective thinking process; listen to and understand students' experiences, beliefs and interpretations of practice; and acknowledge that students are constructing their own understandings and meanings based upon their existing conceptions.
Based on the comments made by the pre-service teachers, and the on-going cycle of action research, various changes will be made to the explicit reflections for the next science methods course. The number of reflections will be reduced, with repetitive reflections being removed. A self-contained booklet will be produced that contains all reflections, along with an introduction, purpose, and more detailed assessment rubrics. Finally, as a means of having more ownership, and encouraging more discussion of the reflections, groups of pre-service teachers will be asked to facilitate each reflection.
The explicit reflective approach to challenging views of science, based on perturbing statements and associated readings, provided experiences from which the pre-service primary teachers discovered, questioned, challenged, and refined their own attitudes and beliefs about science, the teaching and learning of science, and the reflective process.
