Abstract
Objectives This study aims to the international research trend for technology-based teaching content knowledge (TPACK) from a big data bibliographic analysis using the R program.
 Methods For this research, we extracted 809 SCI and SSCI-level research papers from the Web of Science database and detailed bibliographic information of the papers. We conducted network analysis along with big data analysis of sources, keywords, authors, and references. The overall research was conducted through the steps of data collection, data refinement, and data analysis, and the R program was used for data analysis.
 Results As a result of this study, most TPACK research articles were published in educational journals specialized in technology education. And researchers from the United States, China, and Europe formed a research network and conducted TPACK research actively. In addition, as the TPACK concept was not established long ago, studies to form the theoretical framework of TPACK and to verify its validity have been mainstream.
 Conclusions International research on TPACK needs to be conducted more actively in Korea. And also, it is necessary to conduct more research considering various classroom contexts such as gifted, multicultural, and special students and intelligent science labs. In addition, it is required to study the TPACK in a situation where various technology tools are introduced, along with research in subjects other than mathematics and science.
