Topics, publication patterns, and reporting quality in systematic reviews in language education. Lessons from the international database of education systematic reviews (IDESR)

Abstract

Abstract The International Database of Education Systematic Reviews (IDESR.org) contains summary records of published systematic reviews in education and protocols for unpublished reviews and reviews in preparation. During its pilot phase, IDESR is concentrating exclusively on curating systematic reviews in language education. IDESR makes ready access to extant evidence syntheses for researchers, who can use this information to assess the strength of the warrant for any proposed new primary research and/or additional evidence syntheses. By using IDESR to publish review protocols prospectively, review authors commit to high standards of transparency and rigour in producing their research. We have used the data held in IDESR to assess the topics, publication patterns, and reporting quality in the language education literature. We found (i) that language education has seen exponential growth in systematic reviews of research; (ii) that a variety of topics have been addressed, but those related to educational technology have dominated; (iii) that reviews are published in a wide range of outlets, going beyond language education journals; and (iv) that there is room for improvement in the quality of reporting evidence syntheses in language education.
