Introduction
This section identifies and discusses the data collection instruments used in this study; questionnaires and structured interviews. This section further states how data was represented and analysed. It also provides information on how validity and reliability were ensured in the study.
Questionnaires
According to McMillan and Schumacher (2012:194) questionnaires are suitable for a quantitative research study. A questionnaire was used in this study because data was collected from a large sample. The questionnaire was relatively economical and provided the same questions for all subjects. It also ensured anonymity. McMillan and Schumacher further state that questionnaires use statements or questions.

In all cases in this questionnaire, subjects were responding to something written for specific purposes. The disadvantages of questionnaires according to McMillan and Schumacher are the inability to probe, clarify and score open-ended items; faking and social desirability; the restriction to subjects who can read and write; biased and ambiguous items and set responses. To overcome these disadvantages the researcher outlined the objective of the questionnaire, pre-tested the questions and clarified any ambiguities before the final questionnaire was administered. This enhanced the validity and reliability of the research.
Appendix B provides details of the questionnaire used in this study. Structured interviews
According to McMillan and Schumacher (2012), interviews are suitable for qualitative research. In this study, structured interviews were used for the purpose of collecting data from the representative of the Department of Education: Inclusive Education Department and from the Wakkerstroom Circuit manager. McMillan and Schumacher further state that the major step in constructing an interview is the same as preparing a questionnaire: justification, defining objectives, writing questions, deciding general and item format, and pre-testing. The obvious difference is that the interview involves direct interaction between individuals, which has both advantages and disadvantages when compared to a questionnaire. The interview technique is flexible and adaptable.
McMillan and Schumacher further state that an interview can be used regarding many different problems and types of persons, such as those who are illiterate or too young to read and write, and responses can be probed, followed up, clarified, and elaborated to achieve specific accurate responses. Non-verbal and verbal behaviours were noted in face-to-face interviews, and the interviewer had the opportunity to motivate the respondent. The interviews resulted in a much higher response rate than the questionnaires, especially for topics that concerned personal qualities or negative feelings. The primary disadvantages of an interview are its potential for subjectivity and bias, its higher cost and time-consuming nature, and its lack of anonymity. To overcome subjectivity and bias, the researcher was as objective and critical as is possible in the interpretation of results. Time was used economically to avoid wastage.
65 3.5 Data analysis method
It is stated in “The Leard Statistic guide” that descriptive statistics is the term given to the analysis of data that helps describe, show or summarize data in a meaningful way such that, for example, patterns might emerge from the data. Descriptive statistics do not, however, allow us to make conclusions beyond the data we have analyzed or reach conclusions regarding any hypotheses we might have made. They are simply a way to describe our data (Leard Statistics guide).
It further states that descriptive statistics is very important because if we simply presented our raw data it would be hard to visualize what the data was showing, especially if there was a lot of it. Descriptive statistics therefore enables us to present the data in a more meaningful way, which allows simpler interpretation of the data. When we use descriptive statistics it is useful to summarize our group of data using a combination of tabulated description; that is, tables; graphical description; that is, graphs and charts; and statistical commentary, that is, a discussion of the results.
In this study, descriptive statistics was used as an adopted method of data analysis. Data was presented in tables; comparisons were drawn among the respondents with respect to age, gender, knowledge of Inclusive Education and experience in teaching in Inclusive Education setting on the way teachers responded to questionnaire. Data was also represented in figures constructed to display responses. Analysis was done mainly to respond to the research questions and was summarised to address the objectives of the research. Descriptive statistics was used to analyse the data to reflect the level in which the Inclusive Education policy was being implemented in primary schools in the Wakkerstroom Circuit. Qualitative methods were followed to analyse data from the structured interviews.
The statistical tools that are used in this research are tables and graphs. These statistical tools are relevant for descriptive data analysis. In this research, the data from questionnaire was cross-tabulated for ease of presentation and interpretation. However, the raw data from questionnaire had been processed through the SPSS (Statistical Packaging for Social Science) system, and the SPSS output was input into tables. The data from structured interviews was analysed qualitatively, data from different respondents was compared and evaluated in order to make conclusions.
66 3.6 Profile of the four selected primary schools
The schools covered by the study are primary schools that are situated in two different geographic areas of the Wakkerstroom Circuit; that is two schools from the village and two from the farm. They all share constraining factors which may vary in degree. The four schools are situated on the outskirts of the Wakkerstroom Circuit which form part of the Gert Sibande Region of the Mpumalanga province. They are all within a 60 kilometre radius and interaction normally occurs in the form of sports and or professional development workshops. All of these schools are attended by black learners. Most of the learners from these schools are from the village and some are from farms previously owned by white farmers. Most of the learners come from lower class income and unemployed sectors. The village schools are situated in a high density rural settlement and the farm schools are situated in a highly sparse rural settlement. These schools are all classified as historically disadvantaged schools by the Gert Sibande Regional Municipality. Infrastructure, resources and finance are scarce inthese schools.All these schools, however, are compromised regarding delivery of quality education and the effective implementation of the Inclusive Education policy.
