“…The teaching method constitutes one of the largest percentages in developing CT in mathematics education, i.e., 47%. There were four studies performed in ASEAN countries (Cheng et al, 2017;Fang et al, 2017;Matere et al, 2021;Shorey et al, 2021) and 12 studies conducted in non-ASEAN countries (Çoban & Korkmaz, 2021;Critten et al, 2021;Jeng et al, 2020;Marcelino et al, 2018;Mecca et al, 2021;Menolli & Neto, 2021;Mouza et al, 2017;Quitério Figueiredo, 2017;Relkin et al, 2021;Rich et al, 2021;Sung & Black, 2020;Tucker-Raymond et al, 2021). This systematic review explains various types of teaching methods used in developing CT in mathematics, such as instant communication (IM) teaching method (Cheng et al, 2017), innovative curriculum design relying on an Internet-of-Things (IoT) programming course (Jeng et al, 2020), project-based learning and problem-solving learning method (Menolli & Neto, 2021), BootUp's model teaching method (Rich et al, 2021), technological pedagogical content knowledge (TPACK) educational technology course (Mouza et al, 2017), pre-programming (CS0) course (Quitério Figueiredo, 2017), elearning course employing Moodle as a learning management system (Marcelino et al, 2018), designbased learning (Matere et al, 2021), blending learning flipped class (Fang et al, 2017), physical body movement practice (Sung & Black, 2020), coding as another language (CAL) curriculum (Relkin et al, 2021), guided play activities (Critten et al, 2021), online performance-based assessment (Çoban & Korkmaz, 2021) and procedural programming course (Mecca et al, 2021).…”
