A lecture is an oral presentation intended to present information or teach people about a particular subject, for example by a university or college teacher. Lectures are used to convey critical information, history, background theories and equations. A politician's speech, a minister's sermon, or even a businessman's sales presentation may be similar in form of a lecture. Usually the lecturer will stand at the front of the room and recite information relevant to the lecture's content.
Traditionally education is centered on sources such as schools, teachers and print media. The learners reached the information sources by enrolling with schools, teachers and libraries. Prior to the digital era, information was not accessible by the majority of people, and even those accessed were unable to obtain current information with respect to today's context. The modern society wants to know the information as it happens and when it happens, and the world is moving from an information society to a knowledge society. Thus education is given the highest priority and brainpower is becoming the most valuable asset of an organisation. Advances in digital technology have opened up many avenues of learning. Technology has made information accessible / transmittable from anywhere and by / to all groups of people. The higher education landscape is changing rapidly, challenging academic professionals to think critically about their roles in the field.
For a wide variety of reasons, colleges and universities have increased their online course offerings. These programs, including both formal degree programs as well as non-credit and leisure learning options, rely on students to engage with their faculty members as well as other learners to maximize their class experiences. Virtual learning, however, can be a difficult space to create community and resulted in the need to explore how community and culture can be constructed in the virtual, tech-fed world. The model presented here consists of five key elements that program administrators, instructional designers, and teaching faculty must all take into consideration as they develop their courses.
Adult learners have more options for enrolling in postsecondary education than ever before, and they are able to use their learning style preference in deciding which program best meets their needs. For some of these students, those programs are fully online, and for others, there is minimal use of technology. As technology grows and become more integrated into individual lives, the unique learning styles and preferences of adults need to learn to be incorporated into instructional design. Drawing on a regional sample of US colleges, 545 adult learners in a graduate programs were surveyed about how to effectively build community in their online classes. Results indicated some agreement with these instructional tools. Mature adult learners, however, were found to have stronger agreement with strategies that included work outside of the formal online class. These results suggest perhaps a greater comfort for adults in working in spaces where there is less likelihood of being judged or graded, and that they might value relational work with other students in different ways than younger adults.
In the globalization era, social media become more popular in everyone's daily life with its user friendly and effective functions. Social media support the people across the world in communicating, meeting new people, making socialization, sharing knowledge, learning different experiences and interacting with each other instead of distance and separation between persons. Moreover, social media can encourage the increasing of intercultural adaptation level of people who are facing different cultural experiences in new communities. The study shows that people use social media to become more adaptable with the new cultures of the host countries and to preserve their connections with home countries.
A parallel but much smaller body of research has focused on whether, and under what conditions,there may be prosocial outcomes of media use.Over the years, various theories have sought to explain short- and long-termeffects of exposure on viewers' attitudes and behaviors. Although most were developed within the context of media violence research, they also help explain effects of other types of content and predict other outcomes besides physical violence. The founding fathers of our constitution have provided series of specific safeguards for the human resources development in the country. The Directive Principles of State Policy have laid emphasison child development. There is a phenomenal growth of mass media, social media including television all over the globe. A new generation of children has grown up with media exposure in modern society.
