Input enhancement

This study was inspired by VanPatten and Uludag’s (2011) study on the transferability of training via processing instruction to output tasks and Mori’s (2002) work on the development of talk-in-interaction during a group task. An interview was devised as the pretest, posttest, and delayed posttest to compare four intervention types for teaching the simple past passive: traditional intervention as the comparison group and three task-based groups were processing instruction, consciousness-raising, and input enhancement. The interviews and the interactions during the treatments were also analyzed qualitatively. Task-based instruction (TBI) proved significantly more effective than traditional intervention and processing instruction significantly outperformed all others on both posttests. Furthermore, processing instruction was the only task-based intervention to retain its improvement till the delayed posttest. Qualitatively, processing instruction led to true negotiation of meaning and deep-level learning, consciousness-raising led to massive negotiation over the function of the target structure and deep-level learning, input enhancement led to enormous unfocused interaction about meaning, and traditional intervention just led to interaction about the forms. It was concluded that a well-planned processing instruction is a promising intervention for focusing on language form; however, due to the strong points cited for the other two tasks, their roles should not be ignored.

A large number of studies dealing with phonology have focused their attention on phonological production at the expense of phonological perception which provides the foundation stone for phonological production. This study focuses on phonological perception at phonemic level. The purpose of the study is helping beginning learners improve their perception of the English phonemes which are confusable for them. To this end, we propose transcribing as an aural input enhancement device and examine its effect on learners’ phonemic perception. Thirty one females who were randomly assigned to experimental and control groups participated in this study. The experimental group had transcribing exercise during the experiment while the control group did not. The results of the study show that transcribing improves beginning learners’ phonemic perception significantly. Therefore, EFL teachers are advised to include transcribing exercise as one of the techniques to improve learners’ phonemic perception and, hence, their listening comprehension.

The present study investigated comparatively the impact of two types of input enhancement (i.e. textual vs. compound enhancement) on developing grammar ability in Iranian EFL setting. Sixty-five female secondary high school students were selected as a homogenous sample out of about a 100-member population based on Nelson language proficiency test. Then, their grammar ability was measured based on a researcher-made diagnostic test prior to the experiment. The sample was randomly divided into two equal groups; one group received text-enhancement-based instruction of grammar, while the other received compound-based enhancement. Finally, they received an achievement test of grammar as a posttest to measure their progress in light of two different types of input enhancement mechanisms. The pertinent statistical analyses of the results indicated that a) the effect of textual enhancement-based instruction of grammar is not significantly meaningful, while b) the compound enhancement-based instruction has significant effect on learning grammatical structures. Comparatively speaking, therefore, c) compound enhancement-based instruction of grammar is more significantly effective than that of textual in developing grammar ability. It can be safely concluded that grammar instruction and its resultant development are subject to intervention type, which, pedagogically, bears promising messages for both teachers and syllabus designers to incorporate parameters of input enhancement in both teaching and materials development, respectively.

Despite consensus in focus on form (FOF) instruction over the facilitative role of noticing, controversy has not quelled over ways of directing EFL learners’ attention towards formal features via implicit techniques like input-enhancement or explicit metacognitive feedback and interactive peer-editing on the output they produce. This quasi-experimental study investigated the impact of input enhancement (IE), metalinguistic feedback (MF), and peer-editing (PE), on 73 intermediate female Iranian EFL learners’ recognition of relative clauses (RCs). The participants, in three intact classes ranged in age between 18 and 30, were randomly assigned as IE (N=23), MF (N=29), and PE (N=21) groups. The 18-session treatment in all groups was based on identical teaching materials and methodology following a reading to writing orientation focused on RCs. The only difference was related to the focus on form that was through enhanced reading texts in the IE group, metalinguistic feedback on discussion of content in the MF group, and peer-editing in pair-discussion of the content in the PE group. Two parallel sets of 40-item multiple choice researcher-made validated tests focused on RCs were employed to measure the participants’ recognition of RCs at the onset and the end of the study. The one-way between-groups analysis of covariance demonstrated significantly higher gains in the MF and PE groups compared to the IE group; the MF achieved higher levels of mastery. The findings highlight the effectiveness of MF and offer implications for more effective teaching of RCs to Iranian EFL learners.

Vocabulary is one of the essential components of language and learning phrasal verbs as part of vocabulary is quite challenging for foreign language learners. The present study aimed at investigating the effects of visual and auditory input enhancement on learning non-congruent phrasal verbs. The participants of the study were 90 intermediate English language learners who were divided into two experimental and one control groups. The first experimental group received visual input enhancement and the second experimental group auditory input enhancement, and the control group no enhanced material. All three groups were tested on their knowledge of non-congruent phrasal verbs before and after the treatment, using a non-congruent phrasal verb test developed by the researcher. The results of the data analyses indicated that both visual and auditory input enhancement were effective in learning non-congruent phrasal verbs by Iranian EFL learners, and that both groups outperformed the control group in their achievement. 

In the realm of second language acquisition (SLA), task-based language teaching (TBLT) and input enhancement (IE) have been the focus of a great number of studies. However, the idea of investigating the effects of focus on form instruction through input-enhanced tasks along with pre-task planning time as one of the features of task-based language teaching has been rarely explored in the field of SLA. Therefore, the current research set out to examine the impacts of focus on form instruction via textually-enhanced reading tasks along with strategic pre-task planning on L2 learners’ grammatical development in terms of learning English passive voice. For the purpose of the study, 60 intermediate learners of English were selected and divided into two groups of thirty namely as enhanced and unenhanced. Then, each group was divided into two sub-groups of fifteen as +planning and -planning. The participants were provided with a pretest prior to the treatment, then, they were instructed via the materials chosen for the purpose of the study for ten sessions and at the end they were provided with the posttest of the study. Their performance on the pretest and posttest were analyzed to find out the possible effects of the instruction provided throughout the treatment phase. The results revealed that learners who were exposed to enhanced reading tasks along with strategic pre-task planning time outperformed the other learners. The findings of the present study can be of use for language teachers, syllabus designers, and task designers.

: This study investigated the impact of audio-visual input enhancement teaching techniques on improving English as Foreign Language (EFL) learnersˈ collocation learning as well as their accuracy concerning collocation use in narrative writing. In addition, it compared the impact and efficiency of audio-visual input enhancement in two learning contexts, namely traditional and mobile learning contexts. First, 120 homogenous intermediate EFL learners were randomly divided into four groups, two experimental and two comparison groups. Next, two pre-tests, a collocation and a paragraph writing test, were administered. The experimental groups received enhanced target collocations through input enhancement teaching techniques while in the comparison groups the “unenhanced” collocations were taught through conventional simple vocabulary teaching method. After the treatment sessions, the researcher administered two post-tests including a collocation and a paragraph writing. As the data analysis suggested, with regards to the first research purpose, audio-visual input enhancement positively affected EFL learners' collocation learning and enhanced their accuracy concerning collocation use in narrative writing. Regarding the second purpose of the study, the results revealed that, in comparison to traditional learning context, audio-visual input enhancement teaching techniques were significantly effective in mobile learning context in terms of collocation learning. The efficiency of audio-visual input enhancement teaching techniques was not significantly different between the experimental groups in the two learning contexts in terms of enhancing EFL learners’ accuracy concerning collocation use. The findings of this study can create awareness for second language teachers and learners about the critical and beneficial role of input enhancement and mobile assisted language learning in successful language acquisition and learning.

The current study adopted a qualitative-quantitative design to compare the effects of output-based production (OBP) and input enhancement (IE) as two teaching techniques on a group of EFL learners’ writing and also to seek those learners’ perceptions on the two instruction procedures. Accordingly, 65 intermediate learners were selected through convenience nonrandom sampling from among 94 students in intact classes based on their performance on a sample proficiency test (the test had already been piloted among 30 learners). These 65 learners were subsequently divided into two groups consisting of 33 learners in the OBP group and 32 in the IE group. The researchers also made sure that the learners in both groups were homogeneous in terms of their writing prior to the treatment. Next, the treatment in both groups commenced. Once the treatment was over, the researchers gave both groups the same writing posttest. The results of the statistical analysis indicated that the IE group outperformed the OBP group significantly in their writing. The participants further sat for a semi-structured interview comprising five questions about their perception regarding both instructions which demonstrated that the IE group was generally more satisfied with the course than the OBP group. The findings of this study suggest more attention to the incorporation of IE in both English language schools and pre- and in-service teacher training programs.
