E-learning has become a necessity in higher education institutions and is being deployed in educational establishments throughout the world. Researchers have made much emphasis on its benefits but not much is discussed on the disadvantages of e-learning technology. This paper references some of the research work on the limitations of e-learning technology, categorises it in five challenges that teachers are faced with and suggestions for a successful e-learning outcome. This paper also discusses the use of e-learning technology in Middlesex University and some of the challenges they face. Lastly this paper identifies gaps in e-learning literature and calls for further works on this subject.

Access to affordable, objective and scalable biomarkers of brain function is needed to transform the healthcare burden of neuropsychiatric and neurodegenerative disease. Electroencephalography (EEG) recordings, both resting and in combination with targeted cognitive tasks, have demonstrated utility in tracking disease state and therapy response in a range of conditions from schizophrenia to Alzheimer's disease. But conventional methods of recording this data involve burdensome clinic visits, and behavioural tasks that are not effective in frequent repeated use. This paper aims to evaluate the technical and human-factors feasibility of gathering large-scale EEG using novel technology in the home environment with healthy adult users. In a large field study, 89 healthy adults aged 40–79 years volunteered to use the system at home for 12 weeks, 5 times/week, for 30 min/session. A 16-channel, dry-sensor, portable wireless headset recorded EEG while users played gamified cognitive and passive tasks through a tablet application, including tests of decision making, executive function and memory. Data was uploaded to cloud servers and remotely monitored via web-based dashboards. Seventy-eight participants completed the study, and high levels of adherence were maintained throughout across all age groups, with mean compliance over the 12-week period of 82% (4.1 sessions per week). Reported ease of use was also high with mean System Usability Scale scores of 78.7. Behavioural response measures (reaction time and accuracy) and EEG components elicited by gamified stimuli (P300, ERN, Pe and changes in power spectral density) were extracted from the data collected in home, across a wide range of ages, including older adult participants. Findings replicated well-known patterns of age-related change and demonstrated the feasibility of using low-burden, large-scale, longitudinal EEG measurement in community-based cohorts. This technology enables clinically relevant data to be recorded outside the lab/clinic, from which metrics underlying cognitive ageing could be extracted, opening the door to potential new ways of developing digital cognitive biomarkers for disorders affecting the brain.

In this paper, students, and teachers' attitudes towards shifting to an entirely online learning environment were assessed due to COVID-19.  The main objective of the study was to investigate the students’ and teachers' attitudes towards Online learning during the COVID-19 situation in Bangladeshi Government Colleges. Findings revealed that cost and time-effectiveness, safety, convenience, and improved participation were the most frequently cited positive aspects of the online learning experience, while distraction and reduced focus, heavy workload, problems with technology and the internet, lack of ICT knowledge, and poor network infrastructure,  limited availability of educational resources, low attendance of learners, uncooperative learners and insufficient support from instructors and colleagues were the most recurrent negative aspects. The qualitative and quantitative research method was adopted, with semi-structured interviews conducted via Zoom with 10 College teachers and Focus group discussion conducted via Zoom with 18 and survey 100 college students via Google platform from three Bangladesh renowned Government College from Hons 1st year to masters’ level located in Rajshahi divisional district town of the country. A sample of these essays was analyzed using open coding. The findings of the study help instructors and institutions understand students’ and Teachers' attitudes regarding online teaching & learning under abnormal circumstances. Several recommendations informed by the interpretation of the participants’ feedback are offered to assist instructors, administrators, and policymakers improve future online learning experiences.  After conducting the whole study, it can be said that though have some problems adapting to online classes in three regarding BGCs colleges affiliated to the National University of Bangladesh, they are slowly becoming accustomed to it.

Social media connect people by sharing text, photos, audio and videos among themselves. Medical professional and patients also communicate through social media; however, issues of privacy and confidentiality of medical professions in regards to medical and health care decisions contradict with the openness of the usage of social media. Member of the medical profession can use social media but need to abide by the code of conduct of medical ethics in order to render the best possible services. This paper emphasizes on the needs of inclusion of social media usage in future health care providers' curriculum by the higher educational institutions in order to aware of the ethical and professional aspect.

Background: This study explores the effectiveness of educator's training programs regarding the presentation, materials, facilities, relevance and usefulness of the training to the current employment and facilitator’s knowledge using Gagne’s event of instructions. Method: A half day long training was conducted on September 2017 at reach of the two health care teaching institutes. At the end of training, evaluation was done and rated in 5 point Likert scale with 5 as the highest score. Participants agreed that the training was useful and relevant to their work. Result: This study showed a positive perception of the learners which will help their job performance as well as the outcome of their dental teaching school and Gagne’s Events of Instructions can be used when conducting this type of training sessions. Conclusion: Regular training program for staff development need to be carried out following a system approach with right mix of input and contents which process with right sequences of instructions to fill the gap between desired performance and actual staff performance.
