The dynamic world of international policing necessitates seamless communication between officers from diverse linguistic backgrounds. Interpol, the world's largest international police organization, exemplifies this environment. Understanding how politeness strategies are employed within this context is crucial for fostering effective collaboration and information exchange. Due to this significance, the present study investigated the politeness strategies used in emails of L1 and L2 user English-speaking police officers of Interpol. To this end, 100 emails composed by L1 and L2 police officers were obtained from the Interpol office in Tehran, Iran, and the frequency of politeness strategies was calculated by two professional raters. The Chi-square test did not reveal a statistically significant difference in the overall application of politeness strategies between L1 and L2 officers. However, the analysis of individual strategies highlighted some clear variations in usage patterns: L1 user officers employed more politeness strategies than their L2 user counterparts. In addition, the findings revealed that both groups used negative politeness strategies more often than positive strategies. The findings of this study can help police training centers develop a better scope on what structures to focus on in their lesson plans to make their cadets ready to work in the international arena.

The combination of face-to-face and online teaching, also called Blended learning (BL) has practically become one of the prevalent models of teaching and learning all over the world. Particularly, it has been applied as a new trend of using technology to concurrently combine in-class and out-of-class learning to optimize the educational impacts on students. However, BL is still quite a new learning model and has not been applied widely in teaching English in Vietnam. The current study was conducted to explore students’ perceptions of BL, the difficulties students think they have, and the percentage of face-to-face and online learning they prefer when learning in the BL environment. Sixty civil engineering students participating in the survey filled out a questionnaire after the forms of BL and the Learning Management System (LMS) Moodle had been introduced to them. The findings indicated that more than half of the participants were stimulated by BL and willing to take on the challenges.  Nevertheless, some concerns about the lack of IT skills to fulfill the requirements of the BL course cannot be ignored.  

Technology-enhanced language instruction has attracted researchers’ attention in language teaching and learning in recent decades. Accordingly, the present mixed-methods study attempts to investigate the effect of Computer-Assisted Language Learning (CALL) on EFL learners’ vocabulary development and listening comprehension. In doing so, 60 intermediate EFL learners were conveniently chosen for the quantitative phase of the study and were divided into one experimental group (n=30) and one control group (n=30). The teacher-researchers taught vocabulary tasks and listening skills to both groups, using computer software for the experimental group and the traditional method for the control group for 10 sessions for 5 weeks straight. To look into the effect of CALL instruction, quantitative methodology was employed. By analyzing the mean scores of the learners’ pre-test and post-test, it was revealed that the incorporation of computer software in English Language Teaching (ELT) classes resulted in learners’ significant improvement in vocabulary learning and listening comprehension. Then, the qualitative phase of the study began and 24 learners from the same experimental group were invited to semi-structured interviews to share their experiences of CALL classes with the researchers. The qualitative analysis of learners’ data manifested two thematic categories: 1) technology is an asset to EFL learners, and 2) technology makes the input more comprehensible. The findings of the study contributed to the conscious use of technology-enhanced instruction through computer and mobile tools to provide an interactive learning atmosphere for EFL learners, and to help them develop language skills and sub-skills, which seems beneficial for both EFL learners and teachers as ubiquitous technology is becoming an inevitable member of teaching and learning community.

The present study was an attempt to investigate the possible effect of using WordUp Software on Iranian EFL learners’ vocabulary learning. The participants were 60 upper-intermediate EFL learners who were selected out of 72 based on the Oxford Proficiency Test. Then, the participants were randomly divided into two groups of study namely experimental and control. The participants in the experimental group underwent an eight-session treatment including learning vocabulary based on using WordUp Software. In the control group, however, the participants gained new vocabulary by conventional methods. The quantitative approach employed a quasi-experimental method to obtain pre-test and post-test results from learners in both the experimental and control groups. The results of the study revealed that using WordUp Software caused a considerable improvement in learning the vocabulary among the learners in the experimental group. The findings of this study could benefit language learners, language teachers, and curriculum developers by providing valuable insights into vocabulary acquisition through WordUp for EFL learners.
