Education worldwide has emphasized 21st-century competencies, including language competence, computer competence, and thinking skills. Research on Technological Pedagogical Content Knowledge (TPACK), essential teacher knowledge, has attempted to address the need for technology integration to support thinking skills. However, existing TPACK assessments have not intended to help teachers understand the levels of technology integration in teaching English as a foreign language (EFL). Therefore, this study proposed a two-dimensional TPACK scale, allowing EFL teachers to assess their TPACK in integrating technology and thinking skills. In total, 525 EFL teachers responded to this survey online. Scores of this scale were collected to test and establish validity and reliability. The statistical evidence showed that this instrument has high reliability and validity and is helpful for understanding levels of technology integration. The results showed that the EFL teachers were less confident in their TPACK teaching higher-order thinking skills. The EFL teachers in different cultures reported different confidence levels in TPACK and thinking skills (F(6, 518) = 7.83, p < 0.001). The high-achieving EFL teachers reported high TPACK self-efficacy (r = 0.210, p < 0.05). This TPACK survey would be helpful for EFL teachers to understand their development of TPACK in integrating technology and thinking skills in teaching English.
