Instructional technology
Instructional technology
Definition of instructional technology:
Instructional technology is the use of a variety of teaching tools to improve student learning. Usually the teachers use computer and computer software in instructional technology, but the computer is not limited in classroom. According to Commission on Instructional Technology (1970) " Instructional technology is a systematic way of designing, carrying out, and evaluating the total process of learning and teaching in terms of specific objectives, based on research in human learning and communication, and employing a combination of human and nonhuman resources to bring about more effective instruction."
The tools which use in instructional technology:
Instructional technology describes all tools that are used for teaching and learning such as: cameras, CD players, PDA's, GPS devices, computer-based probes, and calculators. Students and teachers use computer software and Internet resources to locate, process, and present information, learn and assess their skills. In state of Blackhurst and Morse, (1996)," Typical applications of instructional technology may use conventional media such as videotapes, computer assisted instruction, or more complex systems, such as hypermedia programs in which computers are used to control the display of audio and visual images stored on videodisc."
The purpose of using instructional technology:
Instructional technology uses technology as a means to solve educational challenges, both in the classroom and in distance learning environments.
Teachers use computers and other instructional technologies to present information they want students to know. They also use computers to assess students' learning and identify and report students' learning needs.
Types of instructional technology:
Interactive White Boards:
Interactive white boards, such as SMART Boards, are now in many classrooms. These interactive boards allow teachers and students to manipulate text and objects and to visit websites for content review. In addition, these boards act as a projector for what's on a computer screen. For instance, if a teacher has a Power Point presentation on her computer, she would use the SMART Board to show it to students. SMART Boards also come with several activities and programs that benefit educators.
Websites and Blogs:
Many teachers now have websites or blogs to keep students and parents up to date. Teachers can simply sign up for a blog on a host site like BlogSpot or Word press. On these sites, teachers should post important dates and even additional content. For instance, a teacher might post a lecture online. Teachers can post important information for parents, such as dates for parent-teacher conferences and important school functions.
Projectors:
These projectors are connected to multimedia projectors and can display any document, not just those that have been copied onto an overhead transparency. Teachers can use projectors such as the Elmo to share text and lesson examples. Students can also easily show other students their work with these projectors. No special copying is needed.
How Instructional Technology Affects Learning:
Instruction Advanced technology could significantly affect the role of teachers, as well as the structure of schools and classrooms. The use of instructional technology changes the teacher’s role from expert to facilitator. Instruction is no longer limited to the school building or classroom. For example, students can take courses from a global satellite feed or on the Internet. Learning can take place at home, at work, or anywhere else that has the capacity for a television, phone, or computer.–
Assessment–Instructional technology will focus more and more on building feedback loops directly into the learning process. Students can obtain frequent and accurate feedback, make corrections to their work, and structure learning experiences around their individual needs. Assessment can be monitored by offsite instructors, plus it can be ongoing and cumulative.
