The study aims to study the processes of the interactive augmented reality technology via blended instruction lesson on cloud, to design the interactive augmented reality technology via blended instruction lesson on cloud, to develop the interactive augmented reality technology via blended instruction lesson on cloud and to study the results of the development of interactive augmented reality technology via blended instruction lesson on cloud. The study's sample was selected using purposive sampling, i.e., 5 people from various higher education institutions and 30 people from undergraduate students in the first year of social sciences division in Pakse Teacher Training College, Lao PDR. The results showed the following: 1) the results of the quality assessment of developed blended instruction lesson on cloud had an overall very high level (mean = 4.51, SD = 0.57); 2) the results of the developed blended instruction lesson on cloud summarised that the results of the post-test achieved a score higher than the pre-test, which is statistically significant at 0.01; 3) the results of the assessment of the digital literacy of students after studying had a good level (mean = 40.73, SD = 2.18); and 4) the results of the student satisfaction to study with the developed blended instruction lesson on cloud were found to have a high level of satisfaction (mean = 4.31, SD = 0.55).
