Intake

The importance of input has been a broadly documented concept in the field of second or foreign language acquisition. However, kinds of input and ways of its presentation are among the controversial issues in L2 classroom research. Therefore, this study was designed to compare the effects of three kinds of input-based instruction on intake and acquisition of the English causative structures by Iranian EFL learners. A total of 105 university students in four intact classes were randomly assigned to four different conditions: processing instruction (PI), textual input enhancement (TE), consciousness-raising (C-R), and control (CO). A pretest/posttest (immediate and delayed) design was used, where participants’ ability to interpret and produce the target structure was assessed through administering a multiple choice interpretation test and a sentence-level production test. Moreover, a grammaticality judgment test was run to assess the amount of intake. Results revealed that learners in the PI group significantly outperformed learners in the other groups on both immediate/delayed production posttests. The findings also indicated that, C-R group could not retain the significant effect of instruction on delayed production posttest and TE tasks were not effective in improving the learners’ production of the target structure. Moreover, the PI group outperformed the other groups on grammaticality judgment test too. Based on these findings, we can conclude that PI which encompasses the most outstanding features of both focus on form and meaning instruction might be a more effective approach in helping EFL learners to acquire the target grammatical forms.

Attention to form in input now seems to have found its way into second language acquisition (SLA), and it is recommended that language learners’ consciousness be raised for language learning to occur and become intake. Input enhancement and output have received considerable attention in recent SLA as two attention-drawing devices. In the present study, we chose visual input enhancement to examine its effect on noticing and acquisition. To that end, two classes were randomly assigned to experimental and control groups. Both groups were exposed to ten different short stories for ten sessions for five weeks, but the type of exposure was different for each group. The English third person singular was highlighted for the experimental group through formatting techniques such as underlining, italicizing, and capitalising. Language learners in the experimental group were supposed to answer the questions following each short story and write a summary for it. Both groups were post tested one week after the treatment on both Noticing Test and a Written Production Test. The results of two independent t-tests showed the superiority of experimental group over the control group in noticing and learning the third person singular. Implications of the findings are discussed.
