Appendix A: Data Coding Scheme and Data Logs

 

All contacts (face-to-face, mail, telephone, e-mail) with each participant, all observations of teaching or interaction between each participant and students or teaching colleagues, and all materials gathered are recorded in the two data logs that follow [data logs are not included in this web version]. For organizational purposes and referencing within the text of this thesis each item has been assigned a code that records: participant, event type, record type, and order in the data collection sequence. The coding scheme is given on the following page. In addition, the data log entries record: form and storage location of the item, date obtained, place where it was obtained, type of event, and a brief description of the contents.
