در ٢٠سال اخیر ترویج آموزش مستقل یکی از دغدغه های طراحان دوره های آموزشی و برنامه ریزان درسی بوده که به لحاظ ایدئولوژیک و روانشناسی نافذ شمرده می شود. با این وجود تخمین آمادگی زبان آموزان برای تغییر به سمت آموزش مستقل قبل از اعمال تغییرات از اهمیت ویژه ای برخوردار می باشد. بنابر این هدف پژوهش کنونی مطالعه ی الگوهای استقلال در میان زبان آموزان ایرانی بوده است. بر اساس تجزیه ی عاملی نتایج پرسشنامه ی میزان استقلال زبان آموزان، مشخص گردید که ٣ عامل زمینه ی رفتار مستقل زبان آموزان را توصیف می کرد. مقاله ی کنونی این ٣ فاکتور را به طور جداگانه تحلیل کرده و در نتیجه تاکید بر استفاده از این ٣ فاکتور در طراحی دروس مبتنی بر آموزش مستقل می نماید.

The present study examines the role of Gal’perin’s Concept-based Instruction (CBI) as a pedagogical approach in teaching cognitive grammar-based (CG-based) concepts of tense and aspect to EFL students. Following the sociocultural theory of L2 Acquisition (SCT), arming L2 learners with scientific concepts can lead to L2 development by deepening their understanding and raising awareness of L2 structures. To this end, over the course of eight weeks 28 third grade middle school students (14 years old) received the concepts in the CBI framework and 30 third grade middle school students received a traditional type of instruction. There were three sets of data including definition of the concepts of tense and aspect before and after CBI, concept verbalization data during CBI, written discourse performance plus responses to a set of grammatical questions before and after CBI. It was found that although both groups improved significantly after receiving the instruction, the students who received CBI performed significantly better than those in the traditional group. The students who received CBI also produced a significant definition of the concepts and their written discourse performance and responses to the grammatical questions improved after CBI. The result provides insight into the application of scientific concepts in L2 instruction.

Many textbooks include semantically related words and sometimes teachers add synonyms, antonyms, etc. to the words in order to present new vocabulary items without questioning the possible effects. This study sought to investigate the effect of teaching vocabulary through synonym, semantically unrelated, and hyponym sets based on Higa’s (1963) proposed continuum. A total of 120 Iranian intermediate EFL adults were selected and classified into two high and low language proficient learners based on their PET (2003) scores. They learned the vocabulary items based on the three above-mentioned methods. Learners’ vocabulary achievement was measured using Paribakht and Wesche’s (1993) Vocabulary Knowledge Scale (VKS) in order to assess both the quantitative (number of learnt vocabulary [NLV]) and the qualitative knowledge of vocabulary (depth of learnt vocabulary [DLV]) by administering the same test twice with a two-week interval for obtaining ST and LT results. To address research questions, two independent two-way ANOVAs and two mixed design two-way ANOVAs were conducted. The results revealed that the learners from synonym sets group gained better ST vocabulary achievement quantitatively and language proficiency level proved not to play any significant role in the learners’ vocabulary accomplishment based on belonging to any given group. It was also revealed that quantitatively hyponym, semantically unrelated, and synonym set groups were respectively the most effective methods of clustering that lead to less forgetting in LT which supports Higa’s proposition.
