The Mo2L instrument can be used to measure different dimensions of the e-learning user experience, i.e. from typical usability attributes such as content, navigation etc. to affective issues such as motivation to learn. The method provides calculation of a total value which takes into consideration all items on the questionnaire and reflects a global usability score of the e-learning application. In addition calculations are made along all the different scales of the questionnaire presenting thus quantifiable information for all the aspects of an e-learning application. Below the main usability constructs and the number of their items are presented:
