This qualitative study is an investigation and assessment of distance learning in Morocco during the COVID-19 pandemic. This research surveyed 3037 students and 231 professors enrolled in different stages of higher education programs. It aims to investigate the limitations of e-learning platforms and how these activities take place at public and private Moroccan universities during the coronavirus confinement. For this purpose, two structured questionnaires were constructed by researchers from different specialties, and the type of data was based on the responses of students and professors from 15 universities. In this paper, we have used three methods: descriptive analysis, regression analysis, and qualitative response analysis. As a data analytics tool, Microsoft Power BI was used to analyze data, visualize it, and draw insights. In this study, both professors and students stated that online learning is not more interesting than ordinary learning and professors need to provide at least 50% of their teaching in face-to-face mode. Recommendations at teaching and technical levels, such as the need for technical support and training in the use of these tools, were provided to enhance and promote distance education in Morocco. The contribution of this paper comes as a result of data analysis obtained from a survey conducted in some famous Moroccan universities.
Growing maintenance costs have become a major concern for developers and users of soft-9 ware systems. Changeability is an important aspect of maintainability, especially in environments where software changes are frequently required. In this work, the assumption that high-level de-11 sign has an in uence on maintainability is carried over to changeability and investigated for that quality characteristics. The approach taken to assess the changeability of an object-oriented 13 (OO) system is to compute the impact of changes made to classes of the system. A change impact model is deÿned at the conceptual level and mapped on the C++ language. In order 15 to experiment the model as a changeability indicator on large industrial software systems, an experiment involving the impact of one change is carried out on a telecommunications system.
17The results suggest that the software can easily absorb that kind of change and that well chosen conventional OO design metrics can be used as indicators of changeability.
