Introduction
In this chapter I present an account of the Data Analysis period. The presentation is in chronological order and my intention is to highlight the evolving stages of data processing as far as the focus of the research as well as the employed techniques are concerned. For this purpose I present an account of
• the data processing during data collection and
• the data processing after data collection
for both the material collected in the tutorial recordings and the interviews. As in Chapter 4 the intention is to establish the links between the conceptualisation of the data analysis methodology of the study, elaborated upon in Chapter 2, and its realisation as it took place during and after observation and interviewing.
Summary: Since March 1994 the recordings of the observed tutorials and the interviews have been selectively transcribed and broken into thematic parts. Episodes related to the novices' learning difficulties have been extracted. The number of Episodes that appear in the final version of Data Analysis was gradually reduced as the focus of the research became tighter. The theorising of the study is grounded on the analysis of the Episodes in each thematic part.
