Previous studies on incidental focus form (FonF) have mostly focused its overall effectiveness. This study is an attempt to further examine the effectiveness of FonF with regard different linguistic categories (vocabulary, grammar, and pronunciation). To this end, eight hours a free discussion English as foreign language (EFL) class 12 upper-intermediate learners were observed, instances episod...

This experimental study evaluated the possible effects of textual input- based enhancement on the acquisition of passive form on Iranian pre-intermediate EFL learners. Sixty Iranian EFL learners at the pre-intermediate level of proficiency were randomly assigned into three groups; two experimental group and one comparison group. The first experimental group received passages in which the passiv...

This study aims to compare the effects of four types of FFI on second language vocabulary learning. To do so, the study adopted a quasi-experimental pretest-posttest design, including five groups, each receiving a distinct treatment. The participants were 80 fourth-grade male students ranging in age from 17 to 19. Before the treatment phase, the participants took a researcher-made test of vocab...

This quasi-experimental study investigated the effects of input-enhancement and production of sentences, containing the target structures, on learning grammar by Iranian Intermediate EFL learners. Sixty male students in three input, output, and control groups participated in the study. After checking the homogeneity of the participants with a proficiency test, the researchers administered a pre...

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 enh...

This quasi-experimental study examines the extent to which research findings from teacher Corrective Feedbacks (CFs) and SLA concerning the efficiency of Focus-on-Form (FoF) pedagogy is transferable to the context of foreign language learning in Iranian schools. To investigate how "grammar instruction with FoF-oriented error treatment" functions as a matrix in which English  learning takes plac...
