Objective:To investigate the current status of the technological pedagogical content knowledge (TPACK) levels of youth teachers in a military medical university, and to provide a practical basis for improving youth teachers' ability to teach with technologies.Methods:Youth teachers (with less than 3 years of teaching experience) in a military medical university were selected by convenience sampling for a survey on TPACK abilities using a modified TPACK questionnaire. The questionnaire was distributed through the internet, and 119 valid responses were returned. SPSS 20.0 software was used to perform the independent samples t-test and one-way analysis of variance.Results:The youth teachers scored highest in technological knowledge [TK; (3.68±0.74)] and lowest in TPACK (3.17±0.74). There were no significant differences in TPACK abilities between youth teachers in different majors. Youth teachers of different educational attainments showed significant differences in the levels of technological knowledge (TK; F=12.99, P<0.001), content knowledge (CK; F=13.64, P<0.001), technological pedagogical knowledge (TPK; F=4.38, P=0.015), technological content knowledge (TCK; F=3.83, P=0.025), and TPACK ( F=3.63, P=0.029)—the TK, CK, TPK, and TCK levels of teachers with doctoral degrees were significantly higher than those with bachelor's and master's degrees. Conclusions:Efforts should be made to design a TPACK ability development system throughout the growth cycle of youth teachers, build teaching practice communities, and improve the system guarantees.
