textual enhancement

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.

This study aimed to investigate the impact of textual enhancement and metalinguistic explanation as focus-on-form tasks tending to encourage the acquisition of nominal clauses (NCs) in English. It explored (a) whether textual enhancement and metalinguistic explanation would promote and enhance the knowledge of NCs, (b) whether these two tasks would differ in terms of enhancing learners' knowledge of nominal clauses, and (c) whether learners' use of self-regulatory capacity for grammar acquisition would have differential effects on textual enhancement and explicit explanation groups. A test of recognizing noun clauses and a test of producing combined sentences were used as both the pretest and the posttest to measure the achievement of first-year undergraduate university students in four intact classes. A grammar self-regulation questionnaire was also administered to measure the use of self-regulatory capacity. The findings demonstrated that both textual enhancement and explicit instruction contributed to developing grammatical knowledge of the learners at both recognition and production level. The results also showed that the learners who received textual enhancement used their grammar self-regulatory capacity more effectively in developing their receptive knowledge of NCs. It can be concluded that textual enhancement, which provides learners with less explicit instruction, pushes them to use their self-regulatory capacity more effectively in improving receptive knowledge of grammar.

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.
