This research is oriented to analyze the implementation of Tuweb and Tuton, platforms combination of emerging technologies in distance learning during Covid-19. A mixed-method study guided the research. The researcher optimized a oneshot case study for the quantitative part, followed by an in-depth interview in supporting data as a qualitative part. The research participants were 27 Master's students of Open University [Universitas Terbuka -UT] in Indonesia who joined the Diffusion of Educational Innovation course. UT fully adopts the distance education system in Indonesia. The research indicated that students' achievement in terms of gender difference, male students better than females in all components of the tutorial evaluation. All tutorial parameters significantly correlated with the coefficient correlation at moderate and high levels. These parameters have also contributed to the achievement score. In contrast, only tutorial discussion via Tuton significantly contributed to the tutorial tasks. It means the presence of Tuweb has little contribution to the tutorial tasks.
