Technology is a broad term, which can mean both artifacts (like machines) and methods of doing things. It also can be used to describe the extent to which a society can manipulate its environment. Generally, technology is the application of scientific knowledge to the practical aims of human life, though it may draw upon a wide range of other fields of knowledge, including engineering, math, linguistics, and history.
Educators have long realized the value of technology in the classroom. Teachers use software programs and the Internet to open up lines of communication with students, enlivening curriculum material and enabling them to work together more easily. Technology can also be used to help students who struggle with memorization and other aspects of the learning process.
The use of technology in the classroom can also provide a means for teachers to assess student progress and give additional support as needed. Students can collaborate with each other using video chats and voice-over-Internet-conferencing software. Students can also answer questions posed by classmates from any location, and teachers can assign projects based on specific technologies.
Despite its utility, there are several problems with technology. For example, overuse of certain technologies can cause eye strain and back pain, and some students can become dependent on them, resulting in a lack of face-to-face communication. Other concerns include privacy issues and the digital divide, where some people have limited access to or cannot afford technology. Moreover, technology can be misused for malicious purposes, such as cyberbullying and hacking.
