Research has shown that writing skill of Iranian learners is not at a satisfactory level. One of the ways to develop writing ability is improving strategic behavior of learners. The current study set out to compare writing performances and patterns of using metacognitive strategies in bilinguals and monolinguals as well as senior and freshmen students. A total of 176 English major university students took part in the study (88 bilinguals and 88 monolinguals). Data were collected through three instruments: a background questionnaire, a writing metacognitive strategy questionnaire, and participants’ compositions. A two-way factorial ANOVA was used to analyze the data obtained through the strategy questionnaire. Since the composition data were not parametric two Kruskall-Wallis tests were employed for data analysis. The results revealed that bilinguals used more metacognitive strategies and had higher writing scores than monolinguals. In addition, seniors had better writing performance than freshmen while the difference between them in using strategies was not significant. Based on the results it can be concluded that teaching writing metacognitive strategies may result in better writing performance.

In response to the increasing interest in and need for a practical brief measure in language testing, this study explored the properties of an offline short-form test (OSF) versus a conventional lengthy test. From the total of 98 vocabulary items pooled from the Iranian National University Entrance Exams, 60 items were selected for the conventional test (CT). To build the OSF, we created an item bank by examining the item response theory (IRT) parameter estimates. Data for the IRT calibration included the responses of 774,258 examinees. Upon the results of the item calibration, 43 items with the highest discrimination power and minimal guessing values from different levels of ability were selected for the item bank. Then, using the responses of 253 EFL learners, we compared the measurement properties of the OSF scores with those of the CT scores in terms of the score precision, score comparability, and consistency of classification decisions. The results revealed that although the OSF generally did not achieve the same level of measurement precision as the CT, it still achieved a desired level of precision while lessening the negative effects of a lengthy test. The results also signified an excellent degree of correspondence between OSF and CT scores and classification results. In all, findings suggest that OSF can stand as a reasonable alternative for a longer test, especially when conditions dictate that a very short test be used.

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 vocabulary as a pretest which was meant to measure the participants’ prior knowledge about the target words. After the treatment phase, the participants took a researcher-made test of vocabulary as posttest to measure the students' achievement of the target words. Independent samples t-test and one-way ANOVA were run to analyze the scores from the pretest and the posttest. The results indicated that there was no statistically significant difference between proactive and reactive FonF in the comprehension mode in terms of promoting vocabulary learning. There was also no statistically significant difference between these two forms of FonF in the production mode in terms of promoting vocabulary learning. However, there was a statistically significant difference between the comprehension-based and production-based FonF in enhancing vocabulary learning. These results extend the positive effect of FFI to L2 vocabulary teaching/learning.

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.
