Educational technology is the effective use of technological tools in learning. As a Concept, іt concerns an array of tools, such as media, machines and networking hardware, as well as considering underlying theoretical perspectives for their effective application.
Synchronous and Asynchronous
Learning can occur in or out of the classroom. It can be self-paced, asynchronous learning or may be instructor-led, synchronous learning. It is suited to distance learning and in conjunction with face-to-face teaching, which is termed blended learning. Virtual classroom can be used by learners and educators in homes, schools, businesses and other
settings for effective online collaboration.
Synchronous learning refer to exchange of ideas and information with others participants during the same period. Examples are face-to-face discussion, online real-time live teacher instruction and feedback, Skype conversations, and chat rooms or virtual classroom where everyone is online and working collaboratively at the same time. Since students are working collaboratively, synchronized learning helps students create an open mind because they
have to listen and learn from their peers. Synchronized learning fosters online awareness and improves many students writing skills.
Asynchronous learning may use technologies such as email, blogs, wikis, and discussion boards, as well as web-supported textbooks, hypertext documents, audio, video courses, and social networking using web. In asynchronous online courses, students proceed at their own pace. If they need to listen to a lecture a second time, or think about a question for a while, they may do so without fearing that they will hold back the rest of the class. Through online course, students can earn their diplomas more quickly, or repeat failed course without the embarrassment of being in a class with younger students. Students have access to an incredible variety of course, internships, sport or work and still graduate with their class.
Computer-based training(CBT) refers to self-paced learning activities delivered on a computer or handheld device such as a tablet or smartphone. CBT initially delivered content via CD-ROM, and typically presented content linearly, much like reading an online book or manual. For this reason, CBT is often used to teach static processes, such as using software or completing mathematical equations. Computer-based training is conceptually similar to web-based training(WBT) which are delivered via internet using a web browser.
Assessing learning in a CBT is often by assessments that can be easily scored by a computer such as multiple choice questions, drag-and-drop, radio button, simulation or other interactive means. Assessments are easily scored and recorded via online software, providing immediate end-user feedback and completion status. Users are often able to
print completion records in the form of certificates.
CBT provide learning stimulus beyond traditional learning methodology from textbook, manual or classroom-based instruction. CBT can be a good alternative to printed learning materials since rich media, including videos or animations, can be embedded to enhance the learning.
Computer-supported collaborative learning(CSCL) uses instructional methods designed to encourage or require students to work together on learning tasks. CSCL is similar in concept to the terminology, “e-leaning 2.0” and “networked collaborative leaning”(NCL).
With technological Web 2.0 advances, sharing information between multiple people in a network has become much easier and use has increased. One of the main reasons for its usage state that it is “a breeding group for creative and engaging educational endeavors.
Using Web 2.0 social tools in the classroom allows for students and teachers to work collaboratively, discuss ideas, and promote information. The collaborative tools prepare students with technology skills necessary in today’s workforce.
