    One of the earliest attempts was advertised in 1728. This was in the Boston Gazette for "Caleb Philipps, Teacher of the new method of Short Hand", who sought students who wanted to learn through weekly mailed lessons. The first distance education course in the modern sense was provided by Sir Isaac Pitman in the 1840s, who taught a system of shorthand by mailing texts transcribed into shorthand on postcards and receiving transcriptions from his students in return for correction. The element of student feedback was a crucial innovation in Pitman's system. This scheme was made possible by the introduction of uniform postage rates across Englandin 1840. This early beginning proved extremely successful, and the Phonographic Correspondence Society was founded three years later to establish these courses on a more formal basis. The Society paved the way for the later formation of Sir Isaac Pitman Colleges across the country. The first correspondence school in the United States was the Soc...

    Internet technology has enabled many forms of distance learning through open educational resources and facilities such as e-learning and MOOCs. Although the expansion of the Internet blurs the boundaries, distance education technologies are divided into two modes of delivery: synchronous learning and asynchronous learning. In synchronous learning, all participants are "present" at the same time in a virtual classroom, as in traditional classroom teaching. It requires a timetable. Web conferencing, videoconferencing, educational television, instructional television are examples of synchronous technology, as are direct-broadcast satellite (DBS), internet radio, live streaming, telephone, and web-based VoIP. Web conferencing software helps to facilitate class meetings, and usually contains additional interaction tools such as text chat, polls, hand raising, emoticons etc. These tools also support asynchronous participation by students who can listen to recordings of synchronous session...

    Most distance education uses a paced format similar to traditional campus-based models in which learners commence and complete a course at the same time. Some institutions offer self-paced programs that allow for continuous enrollment, and the length of time to complete the course is set by the learner's time, skill, and commitment levels. Self-paced courses are almost always offered asynchronously. Each delivery method offers advantages and disadvantages for students, teachers, and institutions. Kaplanand Haenlein classify distance education into four groups according to "Time dependency" and "Number of participants": 1. MOOCs(Massive Open Online Courses): Open-access online course (i.e., without specific participation restrictions) that allows for unlimited (massive) participation; 2. SPOCs(Small Private Online Courses): Online course that only offers a limited number of places and therefore requires some form of formal enrollment; 3. SMOCs (Synchronous Massive Online Courses): Op...

    Distance learning can expand access to education and training for both general populace and businesses since its flexible scheduling structure lessens the effects of the many time-constraints imposed by personal responsibilities and commitments. Devolving some activities off-site alleviates institutional capacity constraints arising from the traditional demand on institutional buildings and infrastructure. Furthermore, there is the potential for increased access to more experts in the field and to other students from diverse geographical, social, cultural, economic, and experiential backgrounds.As the population at large becomes more involved in lifelong learning beyond the normal schooling age, institutions can benefit financially, and adult learning business courses may be particularly lucrative. Distance education programs can act as a catalyst for institutional innovation and are at least as effective as face-to-face learning programs,especially if the instructor is knowledgeabl...

    Barriers to effective distance education include obstacles such as domestic distractions and unreliable technology,as well as students' program costs, adequate contact with teachers and support services, and a need for more experience. Some students attempt to participate in distance education without proper training with the tools needed to be successful in the program. Students must be provided with training opportunities (if needed) on each tool that is used throughout the program. The lack of advanced technology skills can lead to an unsuccessful experience. Schools have a responsibility to adopt a proactive policy for managing technology barriers.Time management skills and self-discipline in distance education is just as important as complete knowledge of the software and tools being used for learning. The results of a study of Washington state community college students showed that distance learning students tended to drop out more often than their traditional counterparts due...

    The modern use of electronic educational technology (also called e-learning) facilitates distance learning and independent learning by the extensive use of information and communications technology (ICT),replacing traditional content delivery by postal correspondence. Instruction can be synchronous and asynchronous online communication in an interactive learning environment or virtual communities, in lieu of a physical classroom. "The focus is shifted to the education transaction in the form of a virtual community of learners sustainable across time." One of the most significant issues encountered in the mainstream correspondence model of distance education is the transactional distance, which results from the lack of appropriate communication between learner and teacher. This gap has been observed to become wider if there is no communication between the learner and teacher and has direct implications over the learning process and future endeavors in distance education. Distance edu...

    Online credentials for learning are digital credentials that are offered in place of traditional paper credentials for a skill or educational achievement. Directly linked to the accelerated development of internet communication technologies, the development of digital badges, electronic passports and massive open online courses(MOOCs) have a very direct bearing on our understanding of learning, recognition and levels as they pose a direct challenge to the status quo. It is useful to distinguish between three forms of online credentials: Test-based credentials, online badges, and online certificates.

    Early years

    Zoom was founded by Eric Yuan, a former corporate vice president for Cisco Webex. He left Cisco in April 2011 with 40 engineers to start a new company, originally named Saasbee, Inc. The company had trouble finding investors because many people thought the videotelephony market was already saturated. In June 2011, the company raised $3 million of seed money from WebEx founder Subrah Iyar, former Cisco SVP and General Counsel Dan Scheinman, and venture capitalists Matt Ocko, TSVC, and Bill Tai...

    In July 2013, Zoom established partnerships with B2B collaboration software providers, such as Redbooth (then Teambox), and also created a program named Works with Zoom, which established partnerships with Logitech, Vaddio, and InFocus. In September 2013, the company raised $6.5 million in a Series B round from Horizon Ventures, and existing investors. At that time, it had 3 million users. In April 2020, the app's CEO, Eric Yuan, announced Zoom's daily users have ballooned to more than 200 mi...

    On April 18, 2019, the company became a public company via an initial public offering. After pricing at US$36 per share, the share price increased over 72% on the first day of trading. The company was valued at US$16 billion by the end of its first day of trading. Prior to the IPO, Dropboxinvested $5 million in Zoom. During the COVID-19 pandemic, Zoom saw a major increase in usage for remote work, distance education, and online social relations. Thousands of educational institutions switched...

    With the increase in demand for cloud collaboration platforms over the past year due to the pandemic, Zoom has grown the partner program and gained momentum around the world. Partnerships with value-added resellers (VARs), Master Agents, service providers, operators and independent software publishers have enabled Zoom to achieve the following objectives: 1. Multiplication by 7 of sales by our partners compared to the previous year 2. More than 20% of our international business activities were driven by our partner ecosystem during the last quarter 3. Zoom's Master Agent activity has seen the fastest growth in history, notably for Avant and Intelisys

    Zoom has been criticized for "security lapses and poor design choices" that have resulted in heightened scrutiny of its software. The company has also been criticized for its privacy and corporate data sharing policies. Security researchers and reporters have criticized the company for its lack of transparency and poor encryption practices. Zoom initially claimed to use "end-to-end encryption" in its marketing materials, but later clarified it meant "from Zoom end point to Zoom end point" (meaning effectively between Zoom servers and Zoom clients), which The Interceptdescribed as misleading and "dishonest". In March 2020, New York State Attorney General Letitia James launched an inquiry into Zoom's privacy and security practices;the inquiry was closed on May 7, 2020, with Zoom not admitting wrongdoing, but agreeing to take added security measures. On April 1, 2020, Zoom announced a 90-day freeze on releasing new features, to focus on fixing privacy and security issues on Zoom. On Ju...

    In April 2020, Citizen Lab warned that having much of Zoom's research and development in China could "open up Zoom to pressure from Chinese authorities." In June 2020, Zoom was criticized for closing multiple accounts of U.S. and Hong Kong–based groups, including that of Zhou Fengsuo and two other human rights activists, who were commemorating the 1989 Tiananmen Square protests. The accounts were later re-opened, with the company stating that in the future it "will have a new process for handling similar situations." Zoom responded that it has to "comply with local laws," even "the laws of governments opposed to free speech." Zoom subsequently admitted to shutting down activist accounts at the request of the Chinese government. In response, a bi-partisan group of U.S. senators requested clarification of the incident from the company.Partially in response to criticisms of its blocking of the activists accounts as well as expressions of concern by the United States Justice Department,...

    In January 2020, Zoom had over 2,500 employees, with 1,396 in the United States and 1,136 in international locations. It is reported that 700 employees within a subsidiary work in China and develop Zoom software. In May 2020, Zoom announced plans to open new research and development centers in Pittsburgh and Phoenix, with plans to hire up to 500 engineers between the two cities over the next few years. In July 2020, Zoom announced the opening of a new technology center in Bangalore, India, to host engineering, IT, and business operations roles. In August 2020, Zoom opened a new data center in Singapore. The company ranked second place in Glassdoor's 2019 "Best Places to Work" survey. Part of Zoom's product development team is based in China, where an average entry-level tech salary is one-third of American salaries, which is a key driver of its profitability.Zoom's research and development costs are 10 percent of its total revenue and less than half of the median percentage among it...
