Evaluation in
Language Teaching
Over
the last two decades, there has been a growing interest in the purpose and
methods of evaluation in language teaching (e.g. Sheldon, 1988; Alderson &
Beretta, 1992; Weir & Roberts, 1994; Ellis, 1997,1998). In the literature,
the term evaluation is used in a number of different ways and based on the
writers’ purpose, various definitions have been proposed. One of the most
‘workable’ definitions of evaluation was provided by Richards et al. (1985:98),
who described evaluation as ‘the systematic gathering of information for
purposes of making decisions’. Although this definition may seem broad, it is
practical as it can be applied to any component of the language curriculum
(needs analysis, objectives, testing, materials, teaching, or the evaluation
process itself). Evaluation plays a crucial role in curriculum development as
it allows instructors, material designers and administrators to assess the
effectiveness and efficiency of a particular language program or any of its
components and make informed decisions about how to proceed. Evaluations can be
macro or micro in scale and can be carried out for either accountability or
developmental purposes or both of these. In macro evaluation, various
administrative and curricular aspects are examined (e.g. materials evaluation,
teacher evaluation, learner evaluation), while micro evaluation focuses on the
specific aspect of the curriculum or the administration of the program such as
evaluation of learning tasks, questioning practices, learners’ participation
etc. (Ellis, 1998). The evaluation in language teaching has been primarily
concerned with the macro evaluation of programs and projects (Ellis, 1998), and
most evaluation studies have been conducted in order to measure the extent to
which the objectives of a program have been met, and to identify those aspects
that can be improved. As Ellis (1998) observes, this kind of analysis is
obviously of interest to teachers as they learn whether or not the goals have
been accomplished and whether any changes should be made to the program.
However, most teachers are less likely to be concerned with the evaluation of
the program as a whole, and more concerned with the extent to which a
particular textbook, or a teaching activity is effective in their teaching
context. The evaluation of teaching materials may be done before they are used
in the classroom in order to determine whether they suit the needs of the
particular group of learners (predictive evaluation), or after the materials
have been used in the classroom in order to evaluate their effectiveness and efficiency,
and teachers’ and learners’ attitudes towards them (retrospective evaluation).
This paper will introduce a systematic procedure for conducting the predictive
evaluation of language teaching tasks
Language
Learning Task: Definition and Componential Framework
Put
simply, learning tasks are a means for creating the conditions necessary for
the acquisition of language. Many definitions of language-learning tasks are
found in the literature, but perhaps the most helpful is that provided by
Richards, Platt and Weber (1985). They define a language-learning task as: “…an
activity or action which is carried out as a result of processing or
understanding language (i.e. as a response). For example, drawing a map while
listening to a tape, listening to an instruction and performing a command, may
be referred to as tasks. Tasks may or may not involve the production of
language. A task usually requires the teacher to specify what will be regarded
as successful completion of the task.” (Richards et al., 1985: 289) The
definition above clearly highlights the key components of a task: (1) language
input, (2) goals (a clearly specified outcome, which determines when the task
has been completed) and (3) activities (what learners need to do in order to
complete the task successfully). The interest in task-based language learning
has been stimulated by psycholinguistic research, which suggests that learners
have their own built-in syllabus, which is often different from the syllabus
proposed by instructors (Ellis, 1998). Thus, the sequencing of the linguistic
input designed by the instructor may not follow the order of the learner’s
linguistic intake. Task-based instruction specifies in broad terms what
language learners will communicate about and the procedures they will follow,
but it gives learners more freedom in terms of the choice of language they use,
allowing them to develop their knowledge and skills in accordance with their
own interlanguage and order of acquisition. Since the mid-1990s, there has been
a growing interest in the effects that the cognitive demands of different tasks
may have on students’ performance and the restructuring of their interlanguage.
One of the most comprehensive frameworks for the analysis of the cognitive
characteristics of language-learning tasks was proposed by Robinson (2001,
2003). Robinson argues that successful task performance depends on the
interaction of multiple factors that operate in three different dimensions:
task complexity, task difficulty and task conditions. Task complexity refers to
the cognitive demands (i.e. the attentional, memory, reasoning and other
processing demands) that the structure of the task imposes on the language
learner. Task difficulty refers to learner factors that may make a task more or
less difficult. This includes affective variables such as motivation, anxiety
and confidence and ability variables such as aptitude, proficiency and
intelligence. Finally, the successful completion of a task also depends on task
conditions or the interactive demands of tasks. Interactional factors include
participation variables (e.g. one-way or two-way task) and participant
variables (e.g. gender, familiarity, power and solidarity). In short, students’
task performance is likely to be influenced by the interaction of multiple
factors across the three componential dimensions. Teachers and material writers
can manipulate these variables either to allow learners access to an existing
L2 knowledge base (a focus on fluency) or to promote form control in learners’
interlanguage (a focus on accuracy).
Predictive Evaluation
A
brief review of the literature relating to materials evaluation reveals that,
to date, the focus of attention has been more or less exclusively on predictive
evaluation. There are two principal ways in which teachers can carry out this
kind of evaluation. One is to rely on evaluations carried out by 'expert'
reviewers. Journals like ELT Journal assist teachers in this respect by
providing reviews of published coursebooks. In some cases (such as the Survey
Reviews this journal provides from time to time), the reviewers identify
specific criteria for evaluating materials. However, in reviews of individual
coursebooks, the criteria often remain inexact and implicit. Alternatively,
teachers can carry out their own predictive evaluations. There are numerous checklists
and guidelines available to help them do so (e.g. Cunningsworth 1984, Breen and
Candlin 1987, Skierso 1991, McDonough and Shaw 1993). These instruments are
generally organized in a manner that reflects the decision-making process which
it is hypothesized teachers go through. Breen and Candlin (1987), for example,
organize the questions in their checklist into two phases, the first of which
enables teachers to address the overall 'usefulness' of the materials, while
the second caters for 'a more searching analysis' based on the teacher's actual
teaching situation. The idea behind these guides is to help teachers carry out
a predictive evaluation systematically. Evaluating course materials
retrospectively However, there are limits to how 'scientific' such an
evaluation can be. As Sheldon (1988: 245) observes, 'it is clear that
coursebook assessment is fundamentally a subjective, rule-of-thumb activity,
and that no neat formula, grid or system will ever provide a definite
yardstick'.
Retrospective Evaluation
This being so, the need to evaluate
materials retrospectively takes on special importance. Such an evaluation
provides the teacher with information which can be used to determine whether it
is worthwhile using the materials again, which activities 'work' and which do
not, and how to modify the materials to make them more effective for future
use. A retrospective evaluation also serves as a means of 'testing' the
validity of a predictive evaluation, and may point to ways in which the
predictive instruments can be improved for future use. Somewhat surprisingly,
however, there are very few published accounts of retrospective evaluations of
course materials, and very little information about how to conduct them. The
bulk of the published literature on evaluation deals with programme or project
evaluation (e.g. Alderson 1992, Weir and Roberts 1994, Lynch 1996). Such
evaluations may incorporate materials evaluation but they are necessarily much
broader in scope. Otherwise, the only other published work on the empirical
evaluation of teaching materials is to be found in accounts of the trialing of
new materials (e.g. Barnard and Randall 1995). The purpose of this article is
to begin to address the question of how retrospective evaluations of materials
can be carried out.
2.2.1 Evaluating
Course Materials Retrospectively
Teachers
can perform a retrospective evaluation impressionistically or they can attempt
to collect information in a more systematic manner (i.e. conduct an empirical
evaluation). It is probably true to say that most teachers do carry out
impressionistic evaluations of their teaching materials. That is, during the
course they assess whether particular activities 'work' (usually with reference
to the enthusiasm and degree of involvement manifested by the students), while
at the end of the course they make summative judgement of the materials.
Empirical evaluations are perhaps less common, if only because they are
time-consuming. However, teachers report using students' journals and
end-of-course questionnaires to judge the effectiveness of their teaching,
including the materials they used. One way in which an empirical evaluation can
be made more manageable is through micro-evaluation. A macro-evaluation calls
for an overall assessment of whether an entire set of materials has worked. To
plan and collect the necessary information for such as empirical evaluation is
a daunting prospect. In a micro-evaluation, however, the teacher selects one
particular teaching task in which he or she has a special interest, and submits
this to a detailed empirical evaluation. A series of micro-evaluations can
provide the basis for a subsequent macro-evaluation. However, a
micro-evaluation can also stand by itself and can serve as a practical and
legitimate way of conducting an empirical evaluation of teaching materials. A
micro-evaluation of teaching materials is perhaps best carried out in relation
to 'task'. This term is now widely used in language teaching methodology (e.g.
Prabhu 1987; Nunan 1989), often with very different meanings. Following Skehan
(1996), a task is here viewed as 'an activity in which: meaning is primary;
there is some sort of relationship to the real world; task completion has some
priority; and the assessment of task performance is in terms of task outcome'.
Thus, the information and opinion-gap activities common in communicative
language teaching are 'tasks'.
