Most published authors were mainly from the United States and Australia. The results of peer-reviewed journals demonstrated that the highest bibliographic link strengths included the International Journal of Science Education-Part B, Journal of Research in Science Teaching, Science Communication, Public Understanding of Science, and Journal of Science Communication. In addition, the most frequently used keywords were science communication, science education, education, human, communication, public understanding of science, and stem.
