There is a riuniber of tools and techniques to find uui wnar goes on in the teaching aiid learniiig practice. Language teachers should be aware that their own attitudes aiid beliefs as well as the observation techniques used will determine what aiid how to observe and tlie type of data to be collected. (see Appendix 2, Samples 3 - 14, 18)

It is also necessary to consider the educational setting including space and equipment arid the time and place where the observation will be carried out. Possible constraints imposed by the specific educational context will need to be taken into account as well.

When planning observation, it is important to consider five crucial aspects in order to get the most out of it: "Joint planning, focus, establishing criteria, observation skills and feedback" (Hopkins, 1993:77).

Joinr planning: A meeting between the observer and the observed must be planned to become familiar and trust each other, to agree on a worthy focus and criteria, to discuss the lesson plan, to establish shared knowledge and to decide other details they,Jeli,eve are ,important, ¡.e. frequency of observation, length, place to sit, and so on. ,,,- ,: Foctrs: There are two possible ways to decide on the focus for observation of the classroom process: open or global and structured or specific. In the global observation, everything is taken into account and commented. The observation on a specific focus centres on a very particular aspect or behaviour, ¡.e. asking questions, pacing, think-time, interaction, rapport, teacher talk, and so on.

Tlie more general the observation is, the more there is a tendency to make jiidgemeots that can be valid, but they are based on the observer's educational values wliicli do not say mucli about the teacher who is under observation.

Estnbli.shint( crilerio: The criteria should be discussed between the teacher researcher and tlie observed ir1 order to reach an agreernent before the observation begins so that it is not threatening.

Ohsct~lcr/iorz skill.~: Obse~ation requires three important skills of tlie observer. First, avoiding, as miich as possible, making judgements. Second, being able to make the person under observation feel confident. Third, selecting, adapting or designing appropriate techniques to collect the right information according to the criteria established.

Feedback: It should be given as soon as possible (within twenty four hours). It must be the result of systematic well-recorded information analysed according to the

eitablished criteria. The observed must be the first one to give hisfier interpretation of the classroom events. The feedback should be the product of the discussion between the two. It should be motivating so that it is the basis for the development of strategies for professional growth.

~ccording to Hopkins (1993:80), "observation is a three phase cycle: planning meeting, classroom observation and feedback discussion." An outline of the cycle is given in the figure below:

The wav in which classroom data is classified or categorised depends on the researchers' personal preferentes and the kind of practice and careful considerations rnade by them beforehand: Many different types of categories have been devised for describing the kind of behaviour engaged in classroom practice. A system of interaction-process analysis was initially devised by Bales (Bell, 1993: 112) in which the observer could classiS, the behaviour of individuals in groups according to twelve categories. Examples of these categories are: "shows tension release" and "shows antagonism." 1 -,,II.!

5. DATA COLLECTION TECHNIQUES IN ACTION RESEARCH

Since action research inust be based on valid, reliable data, accurate data collection techniques should be selected to generate change. Teachers and researchers cannot rely only on perception or personal feelings which can somehow distort the tmth

,

about the class. Careful thought has to be given on deciding exactly how the data for the research will be collected. A range of altematives can be handled by classroom researchers selecting those that will produce the kind of data on which understandings, findings, decisions and judgements can be based.

A rigorous reflection on the type of technique or techniques selected by the teacher researcher is needed regarding the leve1 of clarity of the picture of the process, event ,

or problem they want to tackle in order to make more informed judgements about I everyday classroom work and to reach better decisions about the future actions to be ,

implemented. The selection of data collection techniques is an imporbnt pan of ;

action research because they provide a variety of fírst hand sources of evidence , which needs to be systematically collected within the educational context where the 1 teachen work. 1 1

What techniques to use depends on what the purpose of the research ¡s. Each technique, in general, is useful by itself, but at the beginning of $e enquiry it is not easy to decide what the most suitable technique might be. However, it is important to bear in mind that things little by Iittle begin to clear up as the process goes on and then it is easier to detect which technique is the best for the case.

The techniques used in data collection for action yesearch vary a lot; some of them rely basically on elicitation techniques, others consist mainly in observation, while others rely on introspection.

Eüeitation techniques

surveys I

The purpose of a survey is to find out what is happening or how people think about a specific topic at a particular time. Nunan (1 992: 14 1) mentions the following steps in canying out a survey; ",..define objectives, identi@ target population, review

literature, determine sample, identi& survey instruinents, design survey procedures, identify analytical procedures and determine reporting procedures." 1 2 3

-1s; k - s u - Inlerviews , . , ndi + They can take place between teacher &&server, student and student, teacher and 1 student or observer and student. Interviews can take different directions according to the infomation being sought by the interviewers and the responses provided by the subiects. Even though they are time consuming, they provide useful infonation and immediate feedback. ( s ee~~~pend ix 2, Sample 17) , , , , i i , ,

Quesfionnaires i - , . A. , - A &

They are based on simple precise questions about values of broad aspects such as curriculum, teaching methods or aspects of the classroom. They are time consuming to be prepared and analysed; however, they are practica1 to gtzt specific information from students. (see Appendix 2, Sample 16)

Observation Techniques

Field Notes The teacher makes a written account of the class retrospectively or while it is taking place. In the first case, it is important to rnake the notes as soon as possible so that the information is not distoned. 1

Audio Recordings These ~rovide verv useful infomation about classroom interaction either between teachers and students or among students. However, the time spent transcribing the information recorded can be very long. The tape recorder is a tool favoured by teachers because besides being inexpensive,it is easy to use. 1 , . m ,

Video Recordings These are a more sophisticated way of recording a class. They can be used to observe different aspects of the class, ¡,e. think time, pacing, interaction and so ori. Their main advantage is that they can capture the total classroom context and at tlie same time focus on a specific aspect of it. - 1 -, , ' ,

Classroorn Observation It involves reflection linked to collaborative work between pain of teachers. It is used to collect data on how learners use language in a variety of senings, to study language teaching and leaming processes in the classroom and to study teachers' and

S st~dents' behaviours. Observation aims at examining a phenomenon or behaviour while it is going on. ¤

! ~r would be necessary to make some comrnents on the most and the least significant and frequent entries and on the lack of entries in one or more of the categories. ~inally, inferences about individual contributions might be drawn.

When the focus of the observation is the analysis of the content of a lesson or the kind of topics covered, or the number of contributions and the time spent speaking, specifi~ categories might be devised, according to the researcher's main interest. In figure 8, a vertical line shows that the panicipant spoke for half a minute or less and the foilowing horizontal line indicates that the same participant continued speaiung for the same period of time.

Keeping diaries is a refletive task in which teachers and trainees should be trained focusing on a particular language issue, classroom problem or classroom setting. Regarding this, an action research project carried out by Jirnénez, S. et al (1994) found out that:

According to Progoff, mentioned by Alderson J.E(ed) (1985), the process involved in the shidy of a diary can be summarised as follows:

Buckground deriiils: Before beginning to write their diaries, participants are asked to give information about their previous language experience and learning. Thí information is hoped to be of help when analysing the diary, so that the researcher can uqerstand the diarists' perceptions of their learning process.

1 1,' From Bailey and Ochsner 1983:lW in Nunan, D 1989: 59

E The following table shows the strengths and weaknesses of keeping diaries. However, since tríangulation (see page 33) is recommended in action research projects, other data collection techniques such as audio tape recordings and video tape recordings help overcome diaries' weaknesses.

P r h a r y editing procedure: The diarist should revise the diary when it is for public use. In general, narnes are chang€d and very possibly infomtion that can hann others is omitted. In this way diaria usually contain the most important information for the research, but with some very personal details deleted.

protect confidentiality. (see Appendix 2 . Sarnple 20) ,

Triangulation

A relevarit concept related to data collection is that of triangulation. This nieans 1 that a variety of perspectives, at leas[ two, are necessary iii order to give a real j picture of [he situation being studied. In actiori research, the teacher's and the 1 learner's perspective can contribute to balance tlie level of t ~ t h of the data : gatliered. This could be irnproved if the teacher and two trainees, as observers, ; take data frorn a particular language classroom in order to have more than one single perspective of the issue focused. This type of triangulation is called by Denzin, rnentioned in Allwright and Bailey (1!291:73) "investigation triangulation". Other types can also be known as "data triangulation" in which a variev of 1 I sampling strategies are used to collect data, "rnethodological triangulation" that 1 refers to the use of different techniques such as diaries, observation or self-reports, and finally "theoretical triangulation" in which researchers face the data analysis with more than one perspective in mind. (see Appendix 2, Sarnple 19) 1

(Seliger and Shohamy 1989:U)l)

In deciding which data to select, it is necessary to attempt to identify progressively the focus of the enquiry in the data being analysed until that arnount of information can be separated as relevant or irrelevant to the aims of the enquiry. However, irrelevant information should not be discarded as later it could be necessary. The analysis must try to give sense to the data by explaining what is happening in tht- real context of the classroom, and it should attempt to identify some patterns oi categories.

Guba, E G, rnentioned in Alderson (1985). describes the fundamental criteria to exclude any data that do not fulfil one of the requirements below. m

The data should: , tend to explain existing issues; exernplify the focus of the category; extend the issws of any category; identify or bring to h e surface new issws within a category. relate or bridge several issues within a category: reinforce or refuse existing issues within a category.

The kind of manipulation given to the data will depend on the research approach used and this will determine for example, the need for a qualitative or quantitative analysis.

The model presented by Miles and Huberman in Hopkins ( 1993: 159), describes th@l following s t q s in qualkttive data analysis:
