The study of second language learners' engagement with language learning tasks has become an enchanting line of research since several studies in general education and second language literature have proved its significant effects on learners' ultimate educational success. However, there are several niches in the literature which have not been occupied yet. One of these niches, addressed in this study, is the examination of the effect of computer-mediated condition on second language learners' emotional and social engagement with speaking tasks. Using a repeated-measures design, 40 intermediate language learners performed computer-mediated and face-to-face speaking tasks in a counterbalanced fashion. A questionnaire and semi-structured interviews were employed to collect the required data to respond to the questions. The results showed that learners were more emotionally and socially engaged with the computer-mediated speaking tasks. It was also revealed that low-intermediate learners’ use of social engagement indicators was significantly higher in the computer-mediated condition; however, the change in the condition did not significantly affect the quantity of social engagement indicators provided by high-intermediate ones. The findings also indicated that different engagement dimensions are interconnected, and the change in one of them can affect the other ones.  

The present study investigated the effects of motivational scaffolding on self-determination and learning achievement of field-dependent/independent Iranian EFL learners. To this purpose, quantitative data were elicited and analyzed from 60 intermediate learners who participated in the study as experimental and control groups. The Group Embedded Figures Test (GEFT) was administered to categorize the learner participants into field-dependent and field-independent learners. Then, the scaffold design proposed by Belland et al. was presented to the experimental group, while the control group got all tests and questionnaires with no scaffolding. At the end of 8 training sessions, a self-determination questionnaire was administered to both groups, and then a post-test was applied to examine the impact of scaffolding on learners’ achievement. The statistical analysis of the elicited data showed that the learners’ interaction within motivational scaffolding improved their self-determination and their learning achievement. The findings of the study have implications for teachers and learners in educational settings and help them to detect possible factors affecting EFL learners’ language performance.

This study was conducted to examine the effect of asynchronous computer-mediated condition on L2 learners' speaking ability, speaking apprehension, L2 self-confidence, and willingness to communicate. The participants of this study included 40 intermediate undergraduate students of English language teaching at an Iranian university. The participants were assigned to two experimental (asynchronous computer-mediated) and control (face-to-face) conditions randomly. In the experimental group, the participants practiced speaking in an asynchronous online environment, and in the control group, the students spent a part of their class time accomplishing monologue tasks. Using questionnaires, the participants' speaking ability, speaking apprehension, L2 self-confidence, and willingness to communicate were measured at the beginning and at the end of the term. The findings showed that the monologue speaking ability mean score of those in the computer-mediated group improved significantly more than that of the face-to-face group. Another finding of this study was the superiority of the computer-mediated condition with regard to the participants' speaking self-confidence, speaking apprehension, and willingness to communicate. Overall, the results suggest that asynchronous computer-mediated condition can provide learners with a less-threatening condition that can improve the chances of their L2 monologue speaking ability.

Graphic organizers have been employed to facilitate second language learners' vocabulary knowledge development; however, the examination of the effects of these graphic organizer options on learners' collocation knowledge development has remained unexplored. This research investigated the effects of using teacher-generated, individually-generated, and cooperatively generated graphic organizers on Iranian English language learners' collocation knowledge. The present study examined these effects by studying 80 intermediate second language learners who were selected based on convenience sampling. The participants were assigned to four groups randomly. The collocations were provided on the board in the control group, and explanations were provided orally. In the teacher graphic organizer group, the teacher provided the learners with pre-filled graphic organizers with collocations. In the individually-generated group, the teacher provided the learners with a list of words in groups, and they had some minutes to generate their graphic organizers. In the cooperatively-generated group, the participants had some minutes to generate their graphic organizers cooperatively with their peers. Using a pre-test, immediate post-test, and delayed post-test, the researchers examined the effects of these conditions on learners' collocation knowledge. The findings showed that all graphic organizer groups were more successful than the control group in developing learners' collocation knowledge. In addition, the mean value of the participants’ scores in the cooperative group was significantly more than that of the teacher-generated and individually-generated groups, and there was no significant difference between the mean scores of the teacher and individual-generated graphic organizer groups.  

Although previous studies have shown the benefits of graphic organizers in improving learners' vocabulary knowledge, scant attention has been paid to the possible differences in the effect of individually-developed, cooperatively-developed, and teacher-developed graphic organizers on intermediate L2 learners' vocabulary knowledge. The present study addressed this topic by examining 80 intermediate language learners. The participants were selected based on convenience sampling procedure and studied English in four classes. The learners in the conventional group received the translation/definition of the lexical items. Those in the teacher-generated were provided with the graphic organizers prepared by their teacher, and the participants in the other two groups made the graphic organizers either individually or cooperatively. The researchers employed Vocabulary Knowledge Scale as the pre-test, immediate post-test, and delayed post-test to examine the participants' vocabulary knowledge. The findings of this study indicated that the mean scores of the control group in the immediate and delayed post-tests were significantly lower than those of all graphic organizer groups. In addition, the cooperatively-generated graphic organizer group was significantly more successful than learner and teacher-generated graphic organizer groups, but there was no difference between the learner and teacher-generated groups.

The study investigated the impacts of motivational scaffolding as one of the most effective instructional procedures on self-efficacy and learning achievement of field-dependent and field-independent English language learners. This study attempted to use both qualitative and quantitative data to get more reliable results. As qualitative part, 15 teachers in a semi-structured interview, and as quantitative part, two groups of learners participated as experimental and control groups. Motivated Strategies for Learning Questionnaire was used to determine students' self-efficacy. The Group Embedded Figures Test was administered to categorize them into groups of field-dependent and field-independent. To determine proficiency level, a pre-test and a post-test were used. As treatment, eight sessions of Bandura’s training were administered to improve self-efficacy. Analysis of the qualitative data was conducted using content analysis, and as quantitative analysis, two-way Multivariate Analysis of Variance was conducted. The results showed that learners’ interacting within motivational scaffolding improved their self-efficacy and their learning achievement, and there is no significant difference between learners in the dimensions of field-dependent, field-independent. The findings have implications for teachers and learners in educational settings to detect some factors affecting the English language learners’ language performance and their psychological status.
