{"abstract":"Nowadays, the way young people learn is different from before. Previously, students only listened to each lesson taught by their teachers. But now, there are many ways that students can use to learn, just like using technology. Based on the results of the survey, most of the respondents agree and strongly agree with the statements across all the seven elements of TPACK. This is a clear manifestation that the international teachers in China have adequate knowledge of the use of technology in teaching. This is supported by the advanced facilities where these teacher-respondents are currently teaching. This study could be a basis for policy formulation on how the other countries' education system addresses the shortage and lack of access of teachers to technology tools for an improved teaching and learning process.","abstract_source":"original","authors":["Oliver Logroño"],"date":"2023-06-27","doi":"10.5281/zenodo.8087430","id":1530,"issue":1,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"62303f0e19f1fe4ba1955817d7c4effad2404d467284f54f3c519a211af46e34","schema":"scimatic-article/1","title":"TPACK Proficiency of the International Teachers in China: Basis for Intervention Program","volume":10}
