The nature of knowledge
There are no objective observations, only observations socially situated in the world of the observer and the observed. (Denzin & Lincoln, 1994, p. 12)
In order to capture something of the complex nature of teaching practice, this study employs an interpretivist theoretical perspective within a qualitative research domain. A positivist paradigm holds that objective truth is ‘out there’, meaningfully existing independently from observers, and thus is able to be measured, quantified and replicated. In contrast, the interpretive paradigm is informed by constructionism, an epistemology that holds that ‘reality’ is a set of socially constructed, culturally transmitted meanings. In other words, there is no meaning without humans making it (Crotty, 1998).
Given the socially-‐constructed and contextually-‐dependant nature of knowledge, qualitative research does not present evidence for objective truths, rather it acknowledges that ‘knowledge’ and meanings are constructed, influenced by a particular time and space and by researchers and participants who bring their own preconceptions, meanings and lived experience to the inquiry process. Multiple perspectives on events are therefore both possible and potentially valid. Quantitative methods are often concerned with isolating variables and establishing
‘facts’ – and therefore were not deemed to be as useful in gathering evidence of the complexities of enacted drama practice. Given the complex nature of teaching and the dynamic nature of the classroom, qualitative research methodologies offered the means to document something of this complexity. Thus theory arises from the ‘thick description’ of the phenomenon being studied (Geertz, 1973). Denzin (1989) defines this as
… description that goes beyond the mere or bare reporting of an act (thin description), but describes and probes the intentions, motives, meanings, contexts, situations and circumstances of action. (p. 39)
3.2.1 Drama education research
The purpose of this research is to investigate the way in which drama teachers in New Zealand are implementing drama education in classrooms in the current policy environment. Drama education is now widely taught in New Zealand schools. Teachers undertake drama practice, deliver curriculum and assess learning. There is both an artistic and educative learning process happening, which involves shifting power relationships between teacher and student and between students themselves.
In documenting the practice of drama education, research literature has often focused on the work of specific practitioners and emphasised the connections between their unique histories and their drama teaching. The work of these theorists and practitioners (such as Dorothy Heathcote, Jonothan Neelands, and Phillip Taylor) has contributed to the ways in which drama education is conceptualised at theoretical/curriculum levels and, accordingly, to the way it commonly has been operationalised in classroom settings. Drama education is also informed by the work of theatre practitioners such as Peter Brook, Augusto Boal, and Bertolt Brecht, who explore the aesthetic and dialogic opportunities between theatrical art and the audience.
Each of these practitioners has a different aesthetic, a different process and intention for the kind of experience they hope to provide. Jonothan Neelands emphasises bringing theatre processes and products in the classroom to serve
educational and democratic ends (O'Connor, 2010); Heathcote’s work emphasises an open-‐ended process, the empowerment of student ideas and curiosities, and use of drama as pedagogy for learning across (and beyond) the curriculum. There is a strong emphasis on the social construction of meanings through action and shared reflection on action (Heathcote, 1984). Given that the work of individuals within the drama education field has been influenced by an array of theorists and artistic processes, the methods chosen needed to be sensitive to potential variations in intention and artistic-‐aesthetic process. The chosen methods also need to provide evidence for ‘thick description’ of drama teaching and learning, and of the context in which this occurs.
3.2.2 Case study
Case study is a fitting choice to investigate the field of drama teaching because it allows for rich description of individual drama teaching practice and the bounded context in which this practice occurs. Qualitative inquiry recognises that real-‐life phenomena are contextually bound and does not attempt to discard this influence (Stake, 2003). In order to capture the complexity of a case, evidence is gathered using multiple methods to create a holistic view of the phenomenon, rather than deconstructing it (Yin, 2003).
Given that the focus of the study concerns practice of drama teachers in New Zealand, a single-‐case design was considered insufficient. Although researchers in case study may generalise, “the purpose of a case report is not to represent the world, but to represent the case” (Stake, 2003, p. 156). Despite a shared national curriculum and assessment framework for drama in New Zealand, the practice of individual teachers varies. Variance may occur according to the school environment, the programmes of study developed in specific schools, the teacher’s personality, background, experience, and the philosophical positions they hold in drama education. This study attempts to describe and contextualise variance in practice with the intention of providing rich description of the field. In order to provide richness and variety of description of drama education in New Zealand classrooms, multiple cases were investigated and presented, thus allowing a developing picture of ‘the world’ of New Zealand drama education practice to
emerge. Stake refers to this as “collective case study” (2003, p. 156). In this way, knowledge grows as holistic images of drama practice are juxtaposed with one another, allowing certain resonances and patterns to emerge.
3.2.3 The collective case study – participant selection
This collective case study consists of the work of six experienced drama teachers – in effect, six nested cases forming a collective case. Because the study aims to get at the impact of the recent curriculum and assessment developments in the New Zealand context, it is important that these participants have been practicing teachers prior to these policy developments. Each participant is a member of Drama New Zealand, the national subject association for Drama Education, and has taken professional leadership roles within this context. Each is the Head of Drama in their school and has gained peer esteem in their field. This peer esteem is due to aspects such as their experience in theatre, in teaching and learning, their professional knowledge, artistic achievement and student achievement. In the absence of any objective measure of ability in drama teaching, characteristics such as peer esteem, middle management status in schools, professional leadership, and years of teaching experience provide a means to identify participants who are established in this field.
In order to capture a range of drama teaching practice, the teachers selected have varied interests and strengths within the field of drama education, come from a variety of school settings, and are willing to engage in the research within the given timeframe. I found five teachers working at secondary level and one working at primary level who were willing to participate. Although I approached two other drama specialists working at the primary school level, I did not hear back from them. Because of the rich practice I saw in the work of the one primary teacher who did reply, I chose to include the case despite the imbalance. The difficulty obtaining drama specialists at primary level reflects the fact that there are fewer teachers specialising in drama at this level and fewer numbers participating in professional networks. The final decision to focus on six cases was made to allow both depth and breadth of practice to be investigated, while ensuring the scope of the study met the requirements of doctoral research.
3.2.4 Ethical research practice
Approval to undertake the research was obtained from the University of Canterbury Human Ethics Committee in 2008. In line with requirements from the institution and the objectives of the research, the ethical issues arising from the research design were addressed as follows.
Potential participants were initially approached via email to gauge interest, and once they had indicated they were interested to know more, I sent an information sheet regarding the study (see Appendices). This information sheet outlined the nature of the study, participant involvement and the rights of participants. They were informed they could withdraw at any time prior to data analysis and could pass on any question they did not care to answer during interviews. Once the teacher had given informed consent to participate, information about the study was provided to each school principal, and permission to proceed was gained.
Information sheets were then distributed to every student who attended the particular drama class during the teacher observation and to those students who were willing to speak to the researcher after class. Permission was obtained from each student and, in one instance, permission from the parents/caregivers of students was also obtained (where students were under 13 years old). Video and audio recordings were obtained during the teaching episode and interviews and participants were informed that all data would be destroyed at the conclusion of the research period.
Students who participated in the group interviews were informed that their opinions would be kept confidential in the thesis through the use of pseudonyms. They were also assured that media recordings of classroom work or interviews would not be included in any presentation of the research without further permission being sought.
While the teacher participants gave permission for their real names to be used in the research, I decided to employ pseudonyms to protect individuals (and their schools) from any unforeseen harm resulting from the dissemination of the research.
There were a number of consultation points in the research process after the initial data collection period in order to ensure I hadn’t fallen into developing narratives from my own world view or distorted explanations of participants’ experience (Bourdieu, 1996). Participants were sent a copy of their verbatim transcript and invited to add, delete or clarify their responses, so that the document reflected their views as closely as possible. Several participants did minor edits to these documents to clarify their ideas. Participants were later sent a ‘Case Summary’ of their individual case. This narrative summary drew together findings from the interview, teacher observation, document analysis, and student interviews, providing a more coherent narrative of their teaching practice. Again, participants were invited to confirm that this narrative was a fair and appropriate record of their views and practice, and to make any changes they deemed important.
3.2.5 The role of the researcher
In Lave and Wenger’s terms, I am a member of the drama education ‘community of practice’ (Lave & Wenger, 1991). As a drama educator and former classroom drama teacher myself, I had the advantage of knowing the conventions of drama education, including the central concepts, processes and policy structures participants were grappling with. I am also a member of the professional drama education community, Drama New Zealand, where I had met most participants before and had gained some insight into their work in schools. Furthermore, as a teacher educator, I had an understanding of the competing agendas arising from government, school, and parent communities facing the classroom teacher. It is important to note that this research looks to document the practice of drama education rather than to critique or evaluate the work of participants. I positioned myself as a curious colleague rather than an expert, a stance intended to encourage authenticity and openness in reflection and subsequent reporting of practice by participants (Glesne, 2006, p. 94).
As mentioned above, I took care throughout the data collection process and analysis to share my developing conceptualisations of each case with the participant concerned – in order to ensure my interpretations of their practice were consistent with their own understandings. Qualitative research makes no
assumption that the researcher/observer can be neutral or that the accounts of practice emerging could be free from the interpretive influence of the researcher (Bourdieu, 1996). Therefore the description of practice occurring in the field relies on the co-‐constructed understandings (interpretations) of the researcher and participants.
