latter, there is positive evidence, though it is not clear whether it provides negative evidence. Ellis supports consciousness-raising as a method for self-correction. Ellis suggests that explicit corrective feedback can be useful in the syntactic and other grammatical understandings in the target language by asserting and demonstrating the type of mistake produced in an utterance. Ellis states that by giving students explicit corrective feedback on mistakes, there is the possibility of students internalizing this new grammatical knowledge being learned for future usage. One reason, as mentioned previously, is that after given the explicit feedback, it allows students to witness the grammatical mistakes being made and self-correct the mistake, allowing for the learner to acquire grammatical knowledge of the language. Criticism As a leading theorist in task-based learning (TBL), Ellis has defended TBL from an assertion by Henry Widdowson that the definition of a task is too loose and tends to blur with the concept of an activity. Ellis refutes this claim by explaining that he clearly distinguishes a task from an activity in his works. One of the main ways in which Ellis distinguishes a task from an activity is by arguing the usefulness of each in regard to communication fluency for a task and correct form usage for an activity. Ellis has also contested Paul Seedhouse who argued that such a method could result in pidginized language, to which Ellis claims that it depends on the nature of the task. This method of teaching (TBLT) has been considered by William Littlewood as too difficult for beginner students. The view that Littlewood has against Ellis's TBLT method is that the required knowledge of the target language must already be at a fairly proficient level in order to complete the tasks being carried out. Ellis explains that this is true on the basis that it is a production task; other gap-fill activities can be used by beginners. Ellis further explains that TBLT can be as effective as other methods of teaching a second language whereby the learner may reflect upon their first language as a guide when completing tasks to strengthen comprehension levels in their second language. Michael Swan, protests Ellis in this regard by claiming that TBL is not any more effective than other language teaching methods, since TBL is lacking the structure needed to explicitly teach grammar to learners. Swan claims, that due to this lack of a systemic
