This study compared research trends in universities general English program before and after the COVID-19 pandemic. After analyzing 248 articles from KCI using frequency analysis, centrality analysis, and topic modeling, this study found consistent keywords indicating a focus on learning objectives, effectiveness analysis, satisfaction surveys, and level-based learning before and after the COVID-19 pandemic. Centrality analysis revealed keywords like “teaching, research, analysis” before COVID-19 and “satisfaction, study, level, activity, effect” after COVID-19, indicating a shift towards learner satisfaction, level-based learning, and effectiveness analysis due to the transition to online learning. Topic modeling revealed shifts in research trends: Pre-COVID-19 focused on effective teaching methods, evaluation techniques, and cultural content, while Post-COVID-19 prioritized online teaching methods, web-based platforms, and selfdirected learning. Future research should address self-directed learning, attitudes and goal setting, closing learning gaps in online/blended learning, and developing effective online assessment tools and evaluation strategies. This study provides valuable insights and directions for further research in general English programs.

The primary purpose of this study was to examine prominent features of frequency in the new vocabulary of the middle school English textbooks based on the 2007 revised national curriculum and thereby to provide meaningful data to be compared with those on the 2009 revised national curriculum. This study used an online software (Vocabprofile) to divide words into four categories by frequency: K1 (1-1,000), K2 (1,001-2,000), AWL (Academic Words List), and Off-List Words (the remainder). Salient features discovered from the frequency-based categorization of words in textbooks by grades or publishers were further examined for pedagogical implications regarding textbook writing and curriculum revisions in the future. The analysis has revealed the following results. K1 words accounted for the most among the words presented in English textbooks, reflecting the significance of the high-frequency words in L2 learning. The number of other words showed a steady increase as the grade gets higher. Finally, most textbooks presented multi-words as new vocabulary, which indicates the importance of idioms or collocations. The vocabulary analysis by frequency could be of use to textbook evaluation, considering the growing importance of frequency-based vocabulary teaching.
