This paper presents the results of a virtual ethnographic study developed in an online classroom in a public university in Brazil. The online activities aimed to help 70 students to develop English oral skills in a 60-hourcoursetaught along 15 weeks using the Moodle Language Management System (LMS).After the initial weeks, and some dropouts, there were 59 participants in this study. The course was planned and managed by the authors of this article and some modifications were made along the experience in face of unexpected changes in the learning environment. Having as theoretical support complexity, connectivism, and learning ecology, we assessed digital tools for oral communication and verified that they had a positive impact on language learningand increased learners’ opportunities for language practice. The tools not only contributed to the development of the students’ oral skills but also decreased their anxiety when speaking English.

The purpose of this study was to provide additional research to investigate the effects of mnemonic techniques and digital game-based task on teaching vocabulary to Iranian EFL students through distance education. To that end, a quasi-experimental research method with a pretest posttest non-equivalent control group design was used . The participants of the study were 75 pre-intermediate EFL learners and were chosen from among female learners. After homogenizing the participants through the Oxford Placement Test (OPT), the vocabulary knowledge test (VKS), developed by Wesche and Paribakht (1996), was used as the pretest and the posttest. For measuring the reliability of the test, it was piloted with thirty students who were similar to main sample of the study, which was found to be acceptable in terms of Cronbach’s alpha. The only difference between the pretest and posttest was the order of the items to diminish the practice effect. Then the participants were randomly divided into three equal groups of 25 (two experimental groups and one control group). During a 30-day teaching period, students in the experimental groups were taught English vocabulary using mnemonic and digital game while students in the control group were taught lessons using the traditional methods. After 7 sessions, a posttest of vocabulary was administered. Results of data analysis showed that mnemonic and digital game-based task techniques had a significant effect on teaching vocabulary to Iranian EFL students through distance education. However, no statistically significant difference was found between the effects of the two techniques. The findings of this research may have implications for EFL learners, teachers and curriculum designers.
