테크놀로지 기반 읽기 중재의 동향분석: 특허문헌을 중심으로

The purpose of this study is to grasp changes of reading intervention, which is in the era of the fourth industrial evolution, were accelerated by COVID-19 by utilizing patent analysis and word cloud. In KIPRIS and WISDOMAIN, patent documents collection procedures were conducted through searching by essential keywords. As a result, 69 patent documents were finally collected. Patent documents trend were analyzed according to criteria including years, intervention methods(contents, learning units, reading fluency). voice utilization methods(voice analysis unit, voice change methods, voice error detection methods). In addition, core technology in patent documents were examined through word cloud method. The results of this study demonstrated that the number of reading intervention technology is gradually increasing, and learning related intervention is mostly provided at word and sentence level. Furthermore, pronunciation corrections are the main part of reading intervention contents. When voice data were analyzed, text contrast and voice pattern contrast were main methods. In word cloud, The main keywords of reading related technology are learner, user, foreign language, data, and systems. Based on the results of the study, educational implications for technology based reading intervention are being discussed.
