To ensure the trustworthiness of the results, the analysis was repeated thrice at different times. The results indicate that both the quality of IDLE activities and the quantity of IDLE activities were important to develop English proficiency although receptive activities were still the most dominant.

Several tools and resources were also needed to carry out IDLE activities such as gadgets, internet connection, applications, e-books, e-newspapers, as well as online reading and listening materials.
