Exploring Student’s Experiences and Problems in Online Teaching and Learning During Covid-19 and Improvement of Current LMS Through Human-Computer Interaction (HCI) Approaches

This study tried to explore students’ experiences and problems with online teaching and learning during COVID-19 and the improvement of current LMS through Human-Computer Interaction (HCI) approaches. A mixedmethod approach was used in this project. A triangulation design was used in this study. This study was held at the university level and from Baltistan University; researchers took 12 students through a purposive sampling method. After thematic analysis, a survey was conducted. There are 2000 students at Baltistan University. 200 university students were randomly selected as the sample of this study. Semi-structured interviews and self-developed questionnaires were used as research tools. Thematic analysis and descriptive statistics were used to analyse the data. This study concluded that self-learning, family and teacher issues, financial, internet and light issues, IT assistance, and training needs at the students, teachers, and parental level were collectively described as a human-computer interface in the online teaching-learning process during COVID-19. All the students believed that when their family and teachers’ issues; financial, internet, and light issues, information technological assistance, and parents, students, and teachers’ training are improved then improvement of current LMS through Human-Computer Interaction approaches has occurred in Baltistan university.</p

5Ws of Green and Sustainable Software

: Green and Sustainable Software has emerged as a new and highly active area in the software community. After several years of research and work, we believe that it is now necessary to obtain a general snapshot of how the research in this area is evolving. To do so, we have applied the 5Ws (why, when, who, where, and what), a formula for getting the complete story on a subject. We have therefore carried out a study, using 542 publications related to Green and Sustainable Software research; these were recovered using SCOPUS. The results obtained allow us to conclude that it is important to identify key elements of the research to allow researchers be fully aware of the state of the research on Green and Sustainable Software (why); the study uses papers published between 2000 and the beginning of November 2018 (when); the most prolific authors are mainly from Europe, although the USA is the most active country, Green and Sustainable Software being a very interactive area with a good number of multinational publications (who); the top five keywords related to sustainable aspects are Green Software, Green IT, Software Sustainability, Energy Consumption, and Energy Efficiency (what); finally, as regards the places authors prefer to publish in, there is almost a complete balance between conferences and journals, with a trend towards an increase in the number of publications (where)
