The objective of this study is to analyze the effect of Task-Technology Fit in Perceived Usefulness and Ease of Use of a Distance Education system (Moodle) and assess whether this approach leads to a good explanation of Intention to Use, even in the condition of mandatory adoption. Therefore, following a tradition in this field, a reduced combined model was proposed and tested associating TAM and Technology-Task Fit models. A survey was conducted on a sample of 104 students users of the system. Data were analyzed by PLS - Partial Least Square and bootstrap with 1000 re-sampling. The result indicated that the combination of the models explains much of the variability of Intent to Use (76%), and also the Technology-Task Fit helps to explain significant portions of Ease of Use and Perceived Usefulness. Based on the study, it is expected that managers can pursue mechanisms for mutual adaptation between task and system in distance learning.
