4.4 RESEARCH DESIGN<br />

As already <strong>in</strong>dicated, this study used multiple, <strong>in</strong>teractive qualitative research methods.<br />

It attempted to utilise critical elements <strong>of</strong>case study research and ethnography to pursue<br />

the research agenda. One <strong>of</strong>the limitations <strong>of</strong>case study research is the issue <strong>of</strong><br />

generalization. However, this mode <strong>of</strong><strong>in</strong>quiry enabled me to generate an <strong>in</strong> depth<br />

account <strong>of</strong> contextually relevant issues and pr<strong>in</strong>ciples related to Wenger's theory.<br />

4.4.1 The TEMS community as the empirical field<br />

The TEMS community was a dynamic and constantly chang<strong>in</strong>g group<strong>in</strong>g <strong>of</strong>EMS<br />

teachers. Invitations to the TEMS workshop sessions were sent out to n<strong>in</strong>eteen schools <strong>in</strong><br />

the region. These stressed that attendance at the TEMS workshops was voluntary.<br />

Research participants received a formal letter (see Appendix 1) <strong>in</strong>dicat<strong>in</strong>g the conditions<br />

<strong>of</strong>their participation (one <strong>of</strong>the conditions be<strong>in</strong>g regular attendance at workshop<br />

sessions).<br />

Eleven teachers <strong>in</strong>itially committed themselves to the research project as research<br />

participants. However, the actual number <strong>of</strong>TEMS research participants eventually<br />

constituted a core group <strong>of</strong>seven teachers. The four teachers that dropped <strong>of</strong>fcited work<br />

pressures and personal reasons for their withdrawal. Four other teachers were regular<br />

attendees at workshop sessions but elected not to be part <strong>of</strong>the research project as<br />

research participants. Six teachers attended alternate sessions. These teachers came from<br />

schools that had a policy <strong>of</strong>alternat<strong>in</strong>g their representatives.<br />

The arrival <strong>of</strong>new teachers was a feature <strong>of</strong> every session. The non-appearance <strong>of</strong><br />

previous attendees was also a phenomenon <strong>of</strong>the TEMS community. Three teachers<br />

made a regular habit <strong>of</strong>arriv<strong>in</strong>g for a session, sign<strong>in</strong>g the register, wait<strong>in</strong>g for fifteen<br />

m<strong>in</strong>utes, then quietly exit<strong>in</strong>g the venue. The existence <strong>of</strong>a community <strong>of</strong>practice does<br />

not depend on fixed membership (Wenger 1988). Participants fit <strong>in</strong>to several categories<br />

and assume various roles with<strong>in</strong> the communities <strong>of</strong>practice, such as a coord<strong>in</strong>ator, who<br />
