The aim of this study is to examine the attitudes towards the use of an online learning management system (LMS) by Marshall Cavendish, MC Online among secondary school teachers for teaching purposes. A sample of 78 teachers in a Singapore secondary school was assessed for the MC Online attitude using a Likert type questionnaire with four factors: affect (liking), perceived usefulness, perceived ease of use, and behavioural intention. The findings showed that gender and subject domain did not have strong relationship with teachers' MC Online attitudes. However, there were significant correlation between MC Online confidence level and the teachers' MC Online attitude. Implications for the improvement of the learning management system and further research are provided.
