Analysis of Research Trends in ‘Learning Strategies’ Using Keyword Network Analysis

This study aimed to examine the trends in learning strategy research in South Korea from 2004 to 2023 by collecting research articles related to “learning strategies” published in domestic academic journals and conducting a keyword network analysis. For this purpose, 1,923 keywords from 428 studies on learning strategies published in domestic journals were collected. Based on the collected data, the analysis proceeded as follows: first, a keyword frequency analysis of learning strategy research in South Korea from 2004 to 2023 was conducted. Second, the period was divided into two phases—an early phase (2004-2013) and a later phase (2014-2023)—and the differences in key keywords across each period’s research were analyzed. Third, a network analysis among the keywords was performed. The findings revealed that the main keywords in South Korean learning strategy research over the past 20 years included “academic achievement”, “self-regulated learning”, “learning motivation”, “self-efficacy”, and “university students”. “academic achievement”, “self-regulated learning”, and “learning motivation” were the most frequently appearing keywords across both periods. By examining the differences in keywords between the early and later phases and restructuring the keywords, a network analysis and visualization of the top 29 keywords were presented. Finally, based on these findings, the study proposed the significance and implications of analyzing learning strategy research trends.
