Fossilization has become the focus of many L2 studies since its introduction in 1972 as many learners fail to achieve native-speaker competence. Researchers have tried to unravel the causes of fossilization, among which noticing has been claimed to be of great importance. This study aimed to explore the effect of noticing on fossilization. To achieve this aim, a mixed methods approach was utilized. Sixty advanced L1 Persian learners of English studying in Iran were chosen to perform two written and three spoken tasks twice. Qualitative data included the content analysis of the participants’ performance on the written and spoken tasks while the quantitative data included percentages of noticed errors and recurrent erroneous forms. The errors observed in both performances were counted and classified. Six main categories named Grammatical Errors, Lexical Errors, and Cohesive Errors were identified. The observed errors were further classified into 61 subcategories. When learners’ ability in noticing their errors was investigated, it was found that they could notice 37.4% of the 3,796 fossilized forms they had produced. Most of the errors observed were categorized in the category of grammatical errors. Noticing affected the number of errors produced. It can be concluded that becoming aware of ones fossilized forms, one will produce fewer fossilized forms. The results of the current study have implications for English language teachers and learners. By being informed of the errors learners make while learning a language and how their noticing affects fossilization, teachers can improve their teaching practice which in turn enhances learning.

To date, controversy among scholars exists on whether or not teachers should react to EFL learners' written grammar errors. This study investigated the effect of three feedback types (i.e., selective, comprehensive, and the one recommended by Truscott (1999), that is, no correction) with regard to possible improvements in accuracy in the writings of a total of 66 elementary EFL learners. It, further, sought whether such an effect would last in the long run. During 11 weeks, selected global (e.g., past tense, countable/uncountable, and comparative adjectives) and all grammar errors in the written pieces of the subjects in two treatment groups ( n= 22 in each) were reacted through coded underlining. However, in line with Truscott, the only reaction participants in the third group ( n= 22) received were comments such as great, good, ok, etc.. Analysis of the written pieces in the immediate and delayed post tests  revealed that selective feedback had a significantly more positive influence on learners' accurate use of selected grammatical structures  both in the short and in the long run. The implications are discussed in terms of effective guidelines for teaching writing in EFL contexts. Keywords: Comprehensive feedback; Selective feedback; No correction; Writing accuracy   تصحیح گرامر از نوع بازخورد انتخابی در مقایسه با بازخورد جامع در آموزش نگارش: شواهد متقابل بر دیدگاه تروسکات امروزه در خصوص اینکه آیا  معلم باید به اشتباهات دستوری زبان آموزان  در نگارش باخورد اصلاحی داشته باشد یا نه، در میان پژوهشگران اختلاف نظر وجود دارد. این تحقیق با هدف بررسی تاثیر سه نوع بازخورد اصلاحی( انتخابی، جامع، و نوع توصیه شده توسط تروسکات (1999)،  که بازخورد بدون اصلاح میباشد) بر امکان بهبود  در دقت در نگارش 66  زبان آموز مبتدی انجام شده است. علاوه بر این، این پژوهش به بررسی این تاثیر احتمالی دردراز مدت نیز پرداخته است. در طول 11 هفته،  ساختار های انتخاب شده ( صفات مقایسه ای، اسامی قابل شمارش / غیر قابل شمارش، و زمان گذشته) و تمامی اشتباهات دستور زبان در متن های نوشته شده توسط زبان آموزان در دو گروه تحت بررسی (22 نفر در هر گروه)، از طریق خط تاکید کدگذاری شده مورد بازخورد قرار گرفت. با وجود اینکه، مطابق با نظر تروسکات، تنها عکس العملی که زبان آموزان در گروه سوم (22 نفر) دریافت کردند، نظراتی مانند عالی،  خیلی خوب، خوب، و غیره بود. تجزیه و تحلیل متن های نوشته شده درپس آزمون فوری و تاخیری نشان داد که بازخورد از نوع انتخابی تاثیر مثبت تری در استفاده دقیقتر زبان آموزان از ساختارهای دستوری، هم در کوتاه مدت و هم در دراز مدت بوده داشت. کاربردهای این تحقیق در قالب دستورالعمل های موثر برای آموزش نگارش  زبان خارجی مورد بحث قرار گرفته است. واژگان کلیدی:  بازخورد انتخابی،  بازخورد جامع، عدم بازخورد ، دقت در نگارش

Multiple Choice tests are utilized widely in educational assessment because of their objectivity, ease of scoring, and reliability. This study aimed to compare IF and ID of MC vocabulary test items and attempted to find whether these indices are affected by the number of options. To this end, four 20 item stem equivalent vocabulary tests (3-, 4-, 5-, and 6-option MC) were administered to 194 (106 male and 88 female) pre-intermediate students. Besides, an attitude questionnaire was utilized to examine the attitudes of test takers towards MC test format. Results of one-way ANOVA showed that altering number of options in MC tests does not affect Item Discrimination (ID); however, there were significant differences between Item Facility (IF) of 3-, 5-, and 6-option and 4-, 5-, and 6-option MC test but not between 3- and 4-option MC test, suggesting that 6-option test is the most difficult test. Also, the results of questionnaire revealed test takers’ preference towards the use of 3-option MC. Findings demonstrated that increasing the number of options makes a test more difficult and that choosing the right number of option for MC tests is controversial. Testers are recommended to consider various factors while choosing the right number of options.
