Due to the spread of the pandemic COVID-19 across the world since December 2019, every sector, field, and organization has faced a severe lockdown. The education sector that was following the traditional method of learning has been affected worst. The interaction between the instructor and learner was not possible in such a situation. Their learning process was completely stopped due to social distancing during the lockdown. However, the educational institutions running on the virtual model could continue to work and promote learning. Viewing the uninterrupted teaching-learning process of such institutions in this scenario, the traditional institution also tried to adopt the virtual learning mode. Apart from the advantages, numerous virtual (online) mode challenges hinder the effectiveness and learning outcomes. These obstacles of the virtual (online) mode of learning can be removed primarily when they are identified. So, the first and foremost objective to overcome these obstacles is to find them. This chapter attempts to elaborate on various facets of these challenges: technical, Economic, Security, Practical or Experimental, Assessment or Evaluation, etc.
