The document discusses various techniques for collecting data, including observation, interviews, questionnaires, and focus group discussions. It provides examples and guidelines for each technique. It also discusses potential sources of bias in data collection, such as defective instruments, observer bias, and question wording.
3. Data-collection techniques allow us to systematically collect information about our objects of study (people, objects, phenomena) and about the settings in which they occur. In the collection of data we have to be systematic. If data are collected haphazardly, it will be difficult to answer our research questions in a conclusive way. DATA COLLECTION TECHNIQUES Example: During a class survey three different class scales were used in three schools. The researchers did not record which scales were used in which school. After completion of the survey it was discovered that the scales were not standardized and indicated different institutions when evaluating the same school. It was therefore impossible to conclude in which school bad classes were most prevalent.
4. 1. Using available information Usually there is a large amount of data that has already been collected by others, although it may not necessarily have been analyzed or published. Locating these sources and retrieving the information is a good starting point in any data collection effort. For example , analysis of the information routinely collected by scholar facilities can be very useful for identifying problems in certain interventions or in flows of resources supply, or for identifying increases in the incidence of certain educational problems. Analysis of school information system data, census data, unpublished reports and publications in archives and libraries or in offices at the various levels of education and scholar-related services, may be a study in itself. Usually, however, it forms part of a study in which other data collection techniques are also used.
5. 2. Observing OBSERVATION is a technique that involves systematically selecting, watching and recording behavior and characteristics of living beings, objects or phenomena. Observation of human behavior is a much-used data collection technique. It can be undertaken in different ways: Participant observation: The observer takes part in the situation he or she observes. Non-participant observation: The observer watches the situation, openly or concealed, but does not participate. Observations of human behavior can form part of any type of study, but as they are time consuming they are most often used in small-scale studies. If observations are made using a defined scale they may be called measurements . Measurements usually require additional tools. For example, in checklist of functions we measure the use and the frequency by using scales and a measuring board.
6. 3. Interviewing An INTERVIEW is a data-collection technique that involves oral questioning of respondents, either individually or as a group. Answers to the questions posed during an interview can be recorded by writing them down (either during the interview itself or immediately after the interview) or by tape-recording the responses, or by a combination of both. It is method of data collection that provides a deep understanding of the experience of other people and the meaning they make of that experience. It is a powerful way to gain insight into educational issues through understanding the experience of the individuals whose lives constitute education. Additionally, it helps people to symbolize their experience through language. (Seidman, I. 1991) Interviewing is the art and science of exploring the subjective knowledge, opinions and beliefs of an individual. (Merriam, S. 1998)

13. 4. Administering written questionnaires WRITTEN QUESTIONNAIRE (also referred to as self-administered questionnaire) is a data collection tool in which written questions are presented that are to be answered by the respondents in written form. A written questionnaire can be administered in different ways, such as by: Sending questionnaires by mail with clear instructions on how to answer the questions and asking for mailed responses; Gathering all or part of the respondents in one place at one time, giving oral or written instructions, and letting the respondents fill out the questionnaires; or Hand-delivering questionnaires to respondents and collecting them later.

32. A focus group discussion allows a group of 8 - 12 informants to freely discuss a certain subject with the guidance of a facilitator or reporter. In fact, members have the opportunity to share their insights, seek clarifications on ideas from texts, activities, classes; and make connections between the reading and their classrooms. 5. Focus group discussions (FGD)
33. BIAS in information collection is a distortion in the collected data so that it does not represent reality. Possible sources of bias during data collection: 1. Defective instruments, such as: Questionnaires with: — fixed or closed questions on topics about which little is known (often asking the ‘wrong things’); — open-ended questions without guidelines on how to ask (or to answer) them; — vaguely phrased questions; — ‘ leading questions’ that cause the respondent to believe one answer would be preferred over another; or — questions placed in an illogical order. BIAS IN INFORMATION COLLECTION
34. Observer bias: Observer bias can easily occur when conducting observations or utilising loosely structured group- or individual interviews. There is a risk that the data collector will only see or hear things in which (s)he is interested or will miss information that is critical to the research. Observation protocols and guidelines for conducting loosely structured interviews should be prepared, and training and practice should be provided to data collectors in using both these tools. Moreover it is highly recommended that data collectors work in pairs when using flexible research techniques and discuss and interpret the data immediately after collecting it. Another possibility - commonly used by anthropologists - is using a tape recorder and transcribing the tape word by word.
