This study investigated how teachers of English language perceived and used 21st century learning and innovation skills in their classrooms. Data were collected in both qualitative and quantitative methods and an exploratory case study was employed. The convenience sampling method was used and 105 voluntary teachers of English participated in the questionnaire. To support the quantitative data, 10 English language teachers were interviewed and they completed a KWLA chart after attending a seminar regarding the research. Then, following conducting their session, they were expected to create lesson plans that included 21st century skills and reflection reports. Results demonstrated that the participants in this study are aware of 21st century skills and their importance in English language learning and teaching. Although they are aware of them, they nevertheless require assistance from their managers and the government. Their understanding of how and when to use these skills needs to be improved, along with their horizons.

The more the era has been changing, the more the skills we need have been changing, as well. Living in such a new era brings along the requirement for new skills. 21st-century skills are the skills that we exactly need nowadays as researchers, students, executives, etc. Due to globalization and digitalization, the research focus on 21st-century skills has been increasing day by day, and it is important for researchers to know the gaps in the field and the topics being researched so that they can focus on the gaps and have the possibility to study more to fill those gaps. Grounded on this, the present study aims to find out the most searched topics/keywords, the most cited authors, and the most productive countries on the topic of 21st-century skills in the field of English language teaching, by conducting a bibliometric research study. The results showed that most of the studies focused on creativity, collaboration, communication, and critical thinking, with scant attention to life and career skills while giving an increasing interest in digital literacy skills.

The current systematic review focused on the term “EFL teachers’ self-concept”. To investigate self-concept related articles for the field, many studies including meta-analysis, systematic reviews and other sort of studies have been taken into consideration. The terms “self-concept”, “teachers’ self-concept”, “language teachers’ self-concept” were searched in several databases and accessed 15 relevant studies in EFL context in the last 10 years. The following databases provided these papers: Elsevier, Taylor & Francis Online, Wiley Online Library, Google Scholar, ERIC (EBSCO), Research Online and Research Gate. To investigate EFL teachers’ self-concepts, an in-depth analysis was employed particularly in this study. The initial purpose of the study was to discover several fundamental factors such as theories, instruments and variables which have been generally employed in each of these studies. Furthermore, it is aimed that with this study the term “self-concept” may be better investigated via complex dynamic system theory (CDST) perspective for further research and EFL teachers’ self-concept can be enhanced in future.
