Learner observation tasks as a learning tool for pre-service teachers

2.5.1 System-based approach

By system-based observation Wallace (1991:67) means the observation that is based on a system of fixed and pre-specified categories. They are global in nature, i.e. ‘they are intended to give general coverage of the most salient aspects of the classroom process’ (Wallace 1991:110). Any system contains a finite array of categories. The en

deavour of all system-based observation instruments is the analysis of teacher-class interaction. The two most influential systems are devised by Bellack (1966:267) and by Flanders (1970:314). Wallace (1991:112) has identified the characteristic features of the first system as:

1) the data are measured from a transcript, i.e. the data have to be first recorded and then transcribed;

2) the central place of labelled units of discourse are structure, solicit, response, reaction.

In the ‘Flanders tradition’ there is a form of documented recall where tallies are made every three minutes under one range of categories. In chapter 2.6 the analysis of a range of interaction schemes, their advantages and disadvantages are presented with more details. They are widely used by researchers as they are ready-made, well known and ‘it does not to be trialled and validated’ (Wallace 1991:111).

2.5.2. Ethnographic approach

The observation techniques share many of qualities of ethnographic practices. Ethnography is a detailed sociological observation of people which immerses the researcher in an intense period of observation ‘which guides and informs all subsequent data gathering’. (Radnor 2002:49)

Ethnographical approach is originally developed from the methodologies of field anthropologists and sociologists concerned with studying human behaviour within the context in which that behaviour would naturally occur. Methodologically, ‘anthropological’ classroom studies are based on participant observation, during which the observer immerse him/herself in the ‘new culture’. Initial data gathered by the ethnographer are open-ended and relatively unstructured that ‘allows and encourages the development of new categories’ (Delamont and Hamilton 1976:13). An ethnographer uses a holistic framework. S/he makes no attempt to manipulate, control or eliminate variables. At the same time s/he reduces the breadth of research problems systematically to give more concentrated attention to the emerging salient issues.

The great strength of the ethnographic research is that it gets away from the simplistic behavioural emphasis of the pre-specified codes. (Delamont and Hamilton 1976:37).

The main purpose of the ethnographic approach is the search for meaning and is based on the description of the studied phenomenon. However, Lutz (1986:112) warns that not everyone who can write a paragraph describing an encounter between a teacher and a student is an ethnographer, and he points out that an observer should be trained in ethnographic methods, particularly participant-observer field methods.

2.5.3 Ad-hoc approach

The term ‘ad-hoc’ is used to describe something that has been devised for a particular purpose, ‘with no claims to generality’ (Wallace 1991:113). The ad-hoc approach relates to structured approaches but the categories derive from a particular problem or research topic. That is why this system is more popular with practising teachers. What is more this approach is flexible and eclectic, and involves both quantitative and qualitative data where each seems appropriate. Wallace (1991:113) assumes that each different area of concern will yield a different system of analysis. Ad-hoc approach is considered to be the most appropriate in teacher-training education as it is basically guided discovery approach that drive student-teachers to focus and reflect on an important area of language teaching, and provide a meta-language with which to discuss. The instrument of ad-hoc approach is known as observation tasks (Wajnryb 1992) and is described in Chapter 2.6.2.

2.6. Methods and techniques of observation

2.6.1 Classification of data collection techniques

Seliger and Shohamy (1989:158) present classification of data collection procedures according to the degree of explicitness. On one end of the scale they set broad and general techniques which do not focus on a particular type of data and are considered to be of a low degree, while at the other end they tend to put procedures which are more explicit and structured and thus reveal high degree of explicitness. Collecting data by procedures of a low degree of explicitness is done by means of open and informal description, which tends to be done simultaneously with its occurrence. Typical procedures of this kind are field notes, records, diaries, journals, lesson reports, personal logs, life history accounts, informal interviews with the subjects of observation. Collecting data by means of procedures of a high degree of explicitness involves the use of formal and structured types of data collection procedures. Examples of such procedures are interaction schemes, checklists, observation schedules, observation tasks, formal interviews, surveys, structured questionnaires, case studies, rating numerical scales. Different procedures imply different techniques for data collection. Data obtained from more structured observations are presented in the form of checks, tallies, frequencies, and ratings, while data obtained from the informal observations are presented in the form of narration, field-notes, or transcripts.

According to this classification I am going to describe a range of procedures that are applied to pre-service classroom observation.

2.6.2 Observation instruments

Field notes

Field notes are records of naturalistic observation in the natural context of the behaviour researched through direct listening and watching. The main focus of observation notes is accurate description rather than interpretation. An observer can write down interesting details on various aspects of school life in general and of the teaching process in particulars. ‘Each observational note represents a happening or event – it approximates the who, what, when, and how of the action observed’ (McKernan 1996:94). McKernan considers field notes as a useful tool as

1. they are simple records to keep requiring direct observation

2. no outside observer is necessary

3. problems can be studied in the teacher’s own time

4. they can function as an aide-memoire

5. they provide clues and data not dredged up by quantified means.

At the same time an observer should consider some drawbacks in the use of this technique presented by McKernan (1996:96) as follows:

1. It is difficult to record lengthy conversations

2. They can be fraught with problems of researcher response, bias, and subjectivity
