The researcher collects the data by using the interviews and observations. The semi- structured interviews were used to collect the data. The semi-structured interview was used collect the data for critical question 2 and 3. The reason for using the semi- structured interviews was because it has the flexible questions where the interviewer can probe further with questions to the responses of the interviewees (Newman, 2000). The data was also collected for critical question 1 by the usage of observations. The NS educators were interviewed before they start their lessons and also after their lessons. The researcher was using the semi-structured interviews it was because it's where the
researcher can do the follow up questions to the responses on the participants. These NS educators were interviewed two times because the researcher was aiming to compare the information that they gave to the first interviews and with of the second interview so as validate the information that they gave.
The main aim of using the semi-structured interviews was that this study involves the small number of the participants so the researcher was suppose to use this type of interviews with aim of collecting a lot of data and to go in-depth in data collection (Strauss & Gobin, 1998). The data was collected in these four schools the aim was that the researcher was aiming to collect the data in small sample that at the end it will represent the large population to get the perceptions of the NS educators about teaching this subject using the computers. The semi-structured interviews used for two critical questions it leads the researcher to make the interviews into two parts where the part one consists of the impact of computers in teaching NS and part two was consisting the perceptions ofNS educators about teaching using the computers.
The open-ended questions for the interviews were used to interview the NS educators where they were supposed to give their responses as much as they can. The advantage of open-ended questions was that it allows the participants to provide with a wide range of detailed responses and also permit a researcher to potentially discover many relevant attitudes and experiences being studied. There were sub-questions under each critical question because the researcher was expecting to collect the data that were in order. The advantage of semi-structured interviews was that the researcher was able to get the advantage of able to see the action,attitude and the feeling of the interviewees (Newrnan, 2000).
The interviews were the best in colleting the data of this study because the researcher was getting the direct information from the participants and the researcher was able to rephrase the question if the interviewees were also asking for clarification (Wiston, 1997). The interviews were used in this study because they were less expensive and were having advantage of taking a less time to collect as the researcher questions were cleared.
The purposeful observations were used in this study since the observations was the instrument to collect the data for critical question one. The NS educators were observed in their classes of how they use the computers to teach NS. They were observed after they were interviewed because the researcher was aiming to validate what they said to the interviews was the same to what they do in the class.
The researcher use the semi-structured interviews it was because interviews is an essential tools for gathering information from people who might have difficulties with the wording of written questions or if some are more literate than others (Newman, 2000 &
Wiston, 1997). The researcher was using the semi-structured interviews because it increases the significance and relevance of questions. The semi-structured interviews that was used were built on the emerge from observations where the interview were matched to individuals and circumstances (Newman, 2000). In semi-structured interviews questions were asked in the natural course of teaching using the computers. Since the researcher was using the semi-structured interviews the researcher notices that different information was collected from the different people and this information was less systematic and comprehensive since there questions that were arise to probe further in the responses of the interviewees.
The semi-structured interviews that the researcher used was providing a framework within which respondents express their own understanding of teaching NS using computers. In this type of interview the researcher was aiming to know the specific information concern with the teaching of NS using the computers and then can be compared and contrasted with the information gained in the other interviews. To use this type of interviews the same questions were asked in each interview by doing this the researcher want the interview to remain flexible so that other important information can still arise. In doing these interviews the researcher produces the interview schedule that was having the list of specific questions or list of topics to be asked or discussed (Strauss
& Gobin, 1998). This was taken to each interview to ensure the continuity.The interview
schedule was always updated and revised after each interview with the aim of including more questions which had been arisen as a result of the previous interview.
