“Integrating OD, HR and Change Management: Strategies for Sustained Success”--Insights on AODN and Foresights on Application of OD to Educational Systems

Organizations are facing unprecedented challenges in the 21st century and OD plays a significant role in creating effective responses to these changes.Not only has it been applied in the USA but gains popularity in dynamic Asian region under the megatrend of globalization and information technology.This paper gains insight from Asia Organization Development(OD)Network Summit and discusses future potential application of OD to educational systems.

A Method for Reducing Disorientation in Hypermedia Educational Systems

Learners in hypermedia educational systems （HES） often become disorientated and experience cognitive overhead. This study presents a method for reducing disorientation in HES. The study uses two usability methods, retrospective thinking aloud （RTA） and performance measure （PM）, to find usability problems in HES that impact participant disorientation. The participants had field independent （FI） and field dependent （FD） cognitive styles. The results indicate that the participants＇ disorientation degree using the RTA method is significantly less than those using the PM method. For the effect of cognitive styles, only the average search steps index showed that FI learners are significantly less disorientated than FD learners. The results can help designers of hyperrnedia systems design tools to reduce user disorientation.

Intelligent Interfaces: Pedagogical Agents and Virtual Humans

Little by little, we are entering the new era, intelligent interfaces are absorbing us more and more every day, and artificial intelligence makes its presence in a stealthy way. Virtual humans that represent an evolution of autonomous virtual agents;they are computer programs and in the future capable of carrying out different activities in certain environments. They will give the illusion of being human;they will have a body, and they will be immersed in an environment. They will have a set of senses that will allow them: 1) Sensations and therefore associated expressions;2) Communication;3) Learning;4) Remembering events, among others. By integrating the above, they will have a personality and autonomy, so they will be able to plan with respect to objectives;allowing them to decide and take actions with their body, in other words, they will count on awareness. The applications will be focused on environments that they will inhabit, or as interfaces that will interact with other systems. The application domains will be multiple;one of them being education. This article shows the design of OANNA like an avatar with the role of pedagogical agent. It was modeled as an affective-cognitive structure related to the teaching-learning process linked to a pedagogical agent that represents the interface of an artilect. OANNA, has the necessary animations for intervention within the teaching-learning process.

Impact of COVID-19 on Higher Education System:University Student’s Perspective

Using a qualitative research approach,the current analysis aimed to investigate the COVID-19 pandemic's effect on Bangladesh's higher education from the viewpoint of students.The report comprises a survey of 300 students from higher education institutions.The Convenience sampling method is used to pick fifty university students for the study to collect enough data to answer the test query.They were students from Bangladesh's eight universities(five public universities and three private universities)and three other universities.The pandemic of COVID-19 has wreaked havoc on all facets of human life,including education.It has culminated in learning experiences that have never been seen before.Many schools and universities have shut their doors and moved their teaching and learning to the internet.This study found that there has an effect of COVID-19 on the higher education system in Bangladesh.Both the government and private universities are required to work together to resolve the academic delays as fast as possible,such as the closing of educational schools and the transition to online schooling,which have a serious impact on the education sector and students'lives.This is the first study of Bangladesh.This study tries to find out the problem of education systems and solving the problem of Bangladesh which will be a great effect on the education system of Bangladesh and the economy.

Research and application of the virtual simulation system teaching method in NC machining course

Virtual simulation technology has become one of the most popular technologies in the field of engineering education after the multimedia information technology in recent years.This paper,based on the comprehensive integrated simulation and verification module of UG NX software,describes and discusses a novel virtual simulation system teaching(VSST)for numerically controlled machining to support the student engineering training to achieve the theoretical knowledge and practical techniques in numerically controlled machining.The findings of a study designed to evaluate the impact of VSST for the development of numerically controlled machining course are presented here.In addition,analysis of the follow-up surveys indicates that the VSST method enables to provide the concrete experience of interaction between the students and the simulation environment and to further stimulate students’interest in learning,so that the students who used VSST achieve significantly higher results than their co-workers.
