This paper offers a state-of-the-art working definition for the concept of Critical Thinking (CT hereafter) in an attempt to provide a framework for the development of an operational definition for this complex concept. Having studied various definitions and models, proposed for CT by major figures in the field, the key defining features of this rich concept were identified and classified. Based on these key descriptors, a working definition consisting of three main components namely Mind Analysis , Data Evaluation , and Thinking in Education has been proposed and then each dimension of this definition is defined and elaborated further so that the complexity of the concept could be framed in an extended model. The elaborated conception of CT proposed in this paper seeks to include the core elements of CT so that it can be expandable into an operational definition with measurable items. There are two main reasons for conducting this research: Firstly, CT has evolved into a multifaceted construct with a broad range of cognitive abilities and intellectual dispositions. Secondly, although CT has been recognized as a significant concept in education, its full potential has not been achieved yet.

The present study investigated differential effect of two types of feedback namely, computer-mediated and metalinguistic, on Iranian EFL learners’ writing accuracy. To this end, based on Nelson Proficiency Test (300 A), 69 Iranian advanced EFL learners, including 45 males and 24 females, aged between 17 and 24, learning English in language institutes in Salmas, were selected randomly out of the total population of 121 EFL learners and then divided into three groups. The participants in the two experimental groups received metalinguistic and computer-mediated feedback separately while those in the control group received no feedback. The analyses of the results obtained through a pre-test and a post-test indicated that both feedback types significantly influenced learners’ writing accuracy. However, analysis of the participants’ performances on the post-test demonstrated that metalinguistic group outperformed computer-mediated one. Thus, the effect of metalinguistic feedback was more than that of computer-mediated feedback. In addition, both of them were more influential than no-feedback instruction. The findings of the present study can be fruitful for syllabus designers and EFL teachers. 

Various individual differences, including ambiguity tolerance (AT), have gained momentum because of the influence they can exert on the process and product of learning, and thereby, on various aspects of the learner’s interlanguage system such as accuracy of oral speech. The present study was undertaken to examine the extent to which Iranian EFL learners’ AT was significantly correlated with the accuracy of their task-based speech. To serve the purpose, a random sample of 60 Iranian EFL learners studying English at New Pegah Institute in Tabriz were selected from a population of 150. The Second Language Tolerance of Ambiguity Scale (Ely, 1995) was employed to quantify the participants’ AT while the accuracy of their speech, based on a picture description task, was measured based on the ratio of the grammatical errors to the total number of t-units produced. Correlational analyses of the research data revealed that the participants were highly inaccurate in their oral performance and that there was a significant moderate relationship between the two research variables. The findings underscore the need to determine and promote Iranian EFL learners’ AT and offer a number of pedagogical implications.  

This study investigated the effect of story-based technique, L₁ translation, and Whatsapp emoticon puzzle solving on EFL learners’ learning proverbs. From among 90 female intermediate level learners at two language institutes in Qom, Iran, 60 homogeneous students were chosen following the administration of a sample of Nelson proficiency test and a pre-test. The 60 participants were then assigned to three experimental groups, equal in number. The experimental group 1 was instructed using story-based technique; the experimental group 2 was taught through L₁ translation; and the experimental group 3 was exposed to Whatsapp emoticon puzzle solving. Subsequently, all three groups took part in a proverb post-test similar to the pre-test. The data were analyzed by ANOVA. The results showed that Whatsapp emoticon puzzle solving was significantly the most effective, and that the students’ level of learning proverbs was influenced by story-based technique more than L₁ translation technique. The findings of this study can contribute to technology- enhanced language teaching.

The present study investigated whether word learning and retention in a second language are contingent upon a task's involvement load, i.e., the amount of need, search, and evaluation the task imposes. Laufer and Hulstijn (2001) contend that tasks with higher degrees of these three components induce higher involvement load, and are, therefore, more effective for word learning. To test this claim, 64 Iranian intermediate EFL learners were selected based on their performance on the Preliminary English Test (PET). The participants were randomly assigned to two equal groups. Each group completed different vocabulary learning tasks that varied in the amount of involvement they induced. The tasks were jigsaw task (Group A) and information gap task (Group B). During the ten treatment sessions, recall and retention of the 100 unfamiliar target words were tested through immediate and delayed posttest. Data were analyzed using repeated measure ANOVA. The results indicated that learners benefited more from jigsaw task with higher involvement load. This study supported the Involvement Load Hypothesis, suggesting that higher involvement induced by the task resulted in more effective recall; however, no significant difference was observed between the two tasks in the retention of the unknown words.

Technology mediated learning brings together the users with shared interests. This method makes learners informally engaged in language learning. This study intended to investigate the effect of technology mediated instruction on cognitive scaffolding, academic performance and motivation. Employing a quasi-experimental research, 80 learners from two intact classes at Islamic Azad University, Osku Branch were selected as the experimental and control groups. Telegram as a tool was used in the experimental group, while the control group received traditional way of instruction. Critical ethnography approach was implemented to consider the amount of cognitive scaffolding. To measure the students’ motivational level in both groups, Course Interest Survey (CIS) was administered at the end of the semester. The total average score for each group was calculated. To compare students’ academic achievement, their average scores in the final academic test were considered. An Independent samples t-test in was used to compare the mean scores. The results indicated that technology mediated learning brought about cognitive scaffolding and the students in the experimental group outperformed the control group in terms of motivation and academic achievement. The results of the study suggest that to bring about academically successful students, practitioners should use technology mediated instruction.

This study has been carried out to develop a critical checklist for global/commercial textbooks which play a crucial role in language teaching/learning. For this aim, a number of items have been developed based on a comprehensive review of the related literature and experts’ opinions. The tentative checklist was administered to the targeted population, yet 326 checklists were deemed appropriate for the analysis. The statistical analyses utilized in this study were exploratory factor analysis and partial confirmatory factor analysis. Prior to the exploratory factor analysis, a correlation analysis reduced the items into 44. Next, the exploratory factor analysis identified ten components. Additionally, six items were excluded from the checklist due to simultaneous factor loading and the finalized checklist was truncated into 38 items.  To investigate the possibility for further validation studies, the result of partial confirmatory factor analysis was not statistically significant.  Results of this study have the potentials to shed some lights on the ideological aspects of textbook evaluation.
