vocabulary achievement

This study investigated a new blended approach for enhancing vocabulary achievement. To this end, the project used a convenience sample of 50 intermediate EFL learners ranging from 19-35 years of age from three intact classes studying English translation at university. They were randomly assigned to two groups of 25 students each. In the experimental group, the treatment consisted of providing photos/cartoons related to the sessions’ course of instruction on Instagram, with the learners discussing and exploring the meaning of vocabularies via peer scaffolding using metacognitive strategies. The control group followed the syllabus and assigned homework according to the class program. To investigate the vocabulary achievement of the participants, a piloted multiple-choice vocabulary posttest was administered. The results that were analyzed through independent samples T-test revealed that the blended approach could significantly affect the performance of the experimental group. This study has implications not only for teachers, researchers, and syllabus designers but also for EFL learners with unpacking the notion of metacognition and peer scaffolding, proposing an integrated framework that illustrates how it may pervade the teaching-learning process as an educational goal. The implication of this study supports student responsibility, a student-centered classroom, and higher levels of cognition.

This study examined the effects of cooperative learning techniques (CLT) on vocabulary achievement of reflective/impulsive Iranian EFL Learners. From among 130 students at Fajr institute in Dehdasht, Kohkiloyeh and Boyer Ahmad Province, Iran, 90 participants were selected based on their performance on the Oxford Placement Test (OPT). The participants were then divided into two experimental groups (comprising reflective learners and impulsive learners) and one control group labeled as conventional instruction (CI) group. The instrument used to divide the participants into reflective and impulsive groups was the Eysenck’s (1990) Impulsivity Questionnaire. The experimental groups were taught with the student team achievement division (STAD) technique, while the control group was taught through the traditional method for ten weeks. To measure the vocabulary knowledge of the learners in different groups at the beginning and at the end of the experiment, a pretest and a posttest, each consisting of 40 items on new English words based on their book were used. Independent-Samples and paired-samples t tests were used to determine whether there were significant inter- and intra-group differences. The statistical analysis of the results showed that the experimental groups (reflective and impulsive) performed better on vocabulary achievement posttest than the control group (CI), and also it was revealed that reflective learners performed better on vocabulary achievement than impulsive learners. In sum, cooperative learning enhanced learners’ vocabulary performance, especially the reflective ones.
