Electronic devices are becoming increasingly common in educational environments. The term most commonly used for such devices is "educational technology". This is not actually a new idea, as the rewritable wax tablets, often with lined surfaces to guide novice writers used in antiquity or the blackboard itself are both instances of technological innovations to support pedagogy.
There are many different ways in which electronic devices are used in education. For example, students in STEM (science, technology, engineering, medicine) fields have been making extensive use of sophisticated calculators for many years (the abacus and slide rule were non-electronic predecessors to calculators).
In humanities as well as the sciences, students use computers or equivalent devices to do research and write papers.
In all fields, courses are now likely to have websites, and many instructors use course management software such as Blackboard, to post information for students, record grades, set up online discussions, and check for plagiarism.
In lecture classes, many instructors projects slides or notes on a screen and may even upload lecture notes so that students can review them. Some courses are hybrid, meaning that they have a strong online component, or offered entirely online. Many courses taught in conventional lecture halls are streamed online, and may use devices such as clickers to become more interactive.
Any device (including tablets or cell phones) that instructors incorporate into a learning environment functions as educational technology.
Electronic devices can be used for a large variety of purposes. One of those purposes includes school work. As time goes on, more and more schools are adopting electronic device education by providing their students with electronics such as cameras, laptops, computers, recorders, editing software, and so on. Many classes will also allow the use of tablets, ipods, and phones for taking pictures of lecture notes, or for downloading lecture notes and following along with them on their devices.
Electronic device education, although expensive, is very convenient in allowing students to be able to do their homework nearly anywhere. If a school gives you a laptop and puts most of the classwork online, such as lecture notes, study guides, and maybe even quizzes, then a student can do their work or study anytime they have an internet connection. It also allows for further research. If a student doesn't understand a math question, for example, they can look into other places online that will give them answers to help them understand better. Electronic device education is merely educating through use of digital media.
