co-teaching

Co-teaching is a method that two teachers work together and deliver the instruction in the same classroom to a heterogeneous group of learners. This study was an attempt to find out the effect of one teach-one assist model of co-teaching on Iranian EFL learners’ reading comprehension. To this end, a quasi-experimental design with the pre-test, post-test, and control group was employed and 35 female students within the age range of 15-18 at the elementary level were selected as the participants of the study from Sanjesh-E-No institute in Tabriz, Iran.  They were randomly assigned into the experimental and control groups after taking Key English Test (KET). The experimental group received instruction through two teachers while the control group was taught by a single teacher. Both groups took part in the pre-test and post-test of reading comprehension. The results of an independent-samples t-test revealed that the experimental group had significantly better reading performance compared to the control group. The results of the study can be useful for teachers, students, and any ELT program.

The current study aimed to explore the impact of content and language integrated project (CLIP)-based instruction on electrical engineering students’ vocabulary knowledge. To this end, a sample of 60 electrical engineering students was selected based on their performance on the Cambridge English Objective Proficiency Practice Test (CEOPPT). The participants were subsequently divided into two groups including an experimental and a control group. The study comprised five main stages: administering the proficiency test, conducting a vocabulary pretest, implementing the treatment, administering a vocabulary posttest, and administering a Content and Language Integrated Learning (CLIL) questionnaire. Both groups received CLIP/CLIL instructions over the period of eight sessions. The experimental group, however, received their instructions enriched by the assistance of co-teachers following a team model and supplemented by video-based instructions. At the end of the treatment, the vocabulary posttest and a questionnaire were used to collect the data. The results of a repeated-measures two-way ANOVA revealed that CLIP instruction delivered through co-teaching had a substantial positive effect on the electrical engineering students’ vocabulary knowledge. This finding was further corroborated by the results obtained from the CLIL/CLIP questionnaire, showing the participants’ positive attitude toward CLIP instructions.
