This study aims at examining the relationship between teacher computer-mediated communication (CMC) competence and teacher attitude toward using Frog VLE, a virtual learning platform. This is a non-experimental research using a cross-sectional survey technique through the administration of a set of questionnaires that comprised teacher demographic variables, teacher CMC competence, and teacher attitude toward using Frog VLE. The participants in this study are 351 secondary school teachers from Klang District, Selangor. The results indicated that teachers showed a medium level of attitude and a medium level of CMC competence toward using Frog VLE. Results showed that there is statistically significant direct causal relationship between teacher CMC competence and teacher attitude toward using Frog VLE. CMC motivation and CMC knowledge are the two direct factors of teachers' affective and behavioural attitude toward using Frog VLE, and CMC motivation predict teachers' cognitive attitudes toward using Frog VLE.
