TBL Assessment

Like most teachers today, we take it as a given that communicative ability in a second language must be considered holistically. That is, communicative ability includes not only vocabulary, pronunciation and grammar skills, but also the capacity to use these in real-world contexts. It is this last point which is often missed by traditional assessment tools, largely because it is considered too time-consuming and subjective. We hope to show you that task-based assessment is neither time-consuming nor any more subjective than other methods, and in fact includes other advantages as well.

Task-based assessment can be easy, straightforward and meaningful for learners if looks at the appropriate outcome of a given task first, and at the accuracy of the language used second. In other words, if the learner can achieve the task appropriately, then the learner passes. Conversely, if they cannot achieve the task in a generally acceptable manner, they fail. This presupposes two important factors, which are discussed below: 1) that the task was appropriate to begin with; and 2) what "appropriate" means.

Here is a hypothetical task, including some specific parameters to be met:

Task:

Tell a story

Parameters:

On a simple, familiar topic (e.g., family trip)

To a single sympathetic listener (e.g., a friend)

For a certain length of time (e.g., two minutes)

Note that parameters are important in order to keep tasks at a specific level. For example, if you were to change the “single sympathetic listener” to “an audience of English teachers during a high-stakes university entrance interview” it would make the same basic task far more challenging.

Now, let us say you are grading the task outcome on a 10-point scale. If the learner has appropriately completed the task (i.e., They have managed to tell a story according to these parameters, regardless of how “good” it actually was.), they pass, and now have a score of between 6 and 10.

If they could not accomplish the task (e.g., They could not be understood at all, or if what they produced would not reasonably be called “a story.”) then they fail. If they spoke reasonably well but did not stay completely within the parameters (e.g., If they spoke for only one minute or they spoke on an entirely different kind of topic.) then they did not complete the task, and they fail. Of course, as the teacher, you may always choose to make allowances in such cases, but strictly speaking, in a task-based assessment model, this learner would indeed fail.

The next step is to assess how well the task was achieved. Now we can look at things such as pronunciation, vocabulary and grammar. Remember, if an appropriate outcome was achieved, then we already know that the learner's pronunciation, vocabulary and grammar are at an “acceptable” level for the task, communicatively speaking. They would not have managed to complete the task otherwise.

Thus, task-based assessment works something like this:

Step 1

Was the task appropriately completed? Would the outcome be reasonably recognizable by an “average” native speaker of English as an example of its “type”? (In this case, was it a story? Was there a beginning, a middle and an end? Were the events in the story linked to each other coherently? Was it clear enough to understand, despite any possible language problems such as poor pronunciation or grammar mistakes?)

Yes (pass) No (fail)

Step 2

If “yes,” how good was it? Read the descriptors below and assign a grade from 6 to 10.

If “no,” were there at least some redeeming qualities? Assign a grade from 1 to 5.

Example scoring criteria for a pass:

 10 	No grammar mistakes worth mentioning. Vocabulary use was very appropriate. Pronunciation was exceptionally clear. Speech was remarkably smooth and fluent. Gestures, facial expressions and manner were always appropriate and natural.
 9 	Some small grammar, vocabulary or pronunciation mistakes. However, speech was still very smooth and easy to understand. Gestures, facial expressions and manner were appropriate and natural.
 8 	Some noticeable grammar, vocabulary or pronunciation difficulties. However, overall speech was easy to follow and understand. Gestures, facial expressions and manner were generally appropriate.
 7 	Occasional serious difficulties with grammar, vocabulary or pronunciation. Speech was not always smooth and clear, but quite understandable. Did not revert to first language. Gestures, facial expressions or manner may have been somewhat distracting.
 6 	Serious difficulties with basic grammar, vocabulary or pronunciation. Speech was not always clear. Required some support from the listener. Reverted to first language on occasion. Gestures, facial expressions or manner were often distracting; nevertheless, generally understandable.

Example scoring criteria for a fail:

 5 	Serious difficulties with basic grammar, vocabulary or pronunciation. Required considerable support and patience from the listener. Often reverted to first language; nevertheless, short sections of the speech could sometimes be understandable.
 4 	Serious difficulties with basic grammar, vocabulary or pronunciation. Required considerable support and patience from the listener. Often reverted to first language. Understandable only to a very sympathetic listener familiar with the learner's first language, such as a teacher.
 3 	Did not display an ability to use basic grammar structures. Spoke in two- or three-word utterances using basic, but appropriate vocabulary. Used other means to support speech, including relying very heavily on first language. Difficult to understand even for a very sympathetic listener; nevertheless, displayed some noteworthy quality, such as an understanding of storytelling conventions.
 2 	Did not display an ability to use basic grammar structures. Spoke in two- or three-word utterances using only basic vocabulary. Used other means to support speech, including relying very heavily on first language. Extremely difficult to understand, even for a very sympathetic listener.
 1 	Could not be understood beyond basic set expressions such as “How are you?” Made only single-word utterances, if any at all.

The underlying principle at work in task-based assessment is that tasks can be organized in a hierarchy which parallels “steps” in language proficiency because the language necessary to perform any particular task ultimately indicates an ability to perform that task's “type.”

Feedback

In a task-based approach, specific language forms are never be the primary focus of feedback, because it is important that learners be allowed to make meaning as they see fit, at least at first try. Teachers may assist and even correct learners when asked, of course, but should never restrict the learners' choice of which forms to use by explicitly teaching, say, the present continuous before the task is attempted.

A post-task language feedback phase, on the other hand, is recognized by many task-based practitioners as useful. During this segment of the lesson, after the learners have attempted the task, the teacher may choose to go over the language used, correcting specific errors and/or highlighting particularly well-suited forms that learners did not use, but could have chosen to.
