  1. Source: Field survey (2022).
  2. Bold: Reliability and convergent validity. Reliability also must be achieve in every measurement model. It could be achieve based on several criteria. It is achieve when it get the value of Cronbach Alpha at least 0.7. AVE should be higher than 0.5. However, the value of 0.4 is acceptable due to the condition that if AVE value is less than 0.5, but composite reliability is higher than 0.6, the convergent validity of the construct is acceptable. Cronbach’s alpha = The reliability of all the variables including social presence, cognitive presence, teaching presence, student perception and behavioral intention were in the range of 0.820–0.936. Goodness-of-ft indexes: χ2/df (316) = 2236, RMSEA = 0.065, CFI = 0.917, NFI =0.938, GFI = 0.825, AGFI = 0.821.CR composite reliability, AVE average variance extracted.***p < 0.001.
