Technology is essential for many of our activities, from everyday life to the creation of modern medicines and devices. It provides the means to manipulate the environment and generate energy, and it has shaped the way we live and work. Technology helps us measure things, collect data, process samples, and compute results. It also helps us protect ourselves from dangerous materials, transport samples, and develop new instruments.
Technology includes hardware, software, and networking. Hardware includes the physical components of a computer and network. Software consists of the applications that computers run. Software helps the computer work efficiently, and can be used for entertainment or to make tasks easier. Word processing software, for example, can help you create documents faster. Audio and visual technology includes cameras, microphones, projectors, and other devices for recording and displaying sound and visual mediums. These technologies are often combined with each other.
Technology has changed the course of human history and the nature of human society. It has influenced the spread of civilization. Agricultural technology, for example, has had a greater impact on human life than any political revolution in history. Other important technology innovations include sanitation and preventive medicine. Despite its role in human development, technology is not without controversy. It has influenced how humans live and work in communities across the world, and has contributed to the emergence of cities and the rise of urbanization.
The widespread use of technology creates risks that may be unintended. People may be advised to reduce or stop using it entirely. Often, the consequences of technology may be more harmful than the benefits. However, scientists can estimate the risks and benefits of a technological advancement based on a combination of the likelihood of the undesirable outcomes and a measure of the harm. With these figures, they can compare different technological designs.
Technology is a broad field that encompasses many different fields. Understanding how technology works will help students organize their own thinking about the field. Furthermore, it will allow them to develop a balanced and holistic understanding of the field. By defining technology concepts, students will be able to see the common patterns across these areas.
Technology can help schools transform their educational experience by empowering educators and students. It allows educators to build personalized learning environments with real-time feedback, and it makes learning relevant to students' lives. It also inspires them to become problem-solvers, collaborators, and creators. There are many examples of this kind of use of technology in education, and it's a very exciting topic for the future.
The purpose of educational technology is to enhance teaching and learning across the curriculum and support key administrative functions. Regardless of the type of technology, educators must ensure that it supports the standards for teaching and learning. It should also help improve communications and provide support for primary administrative functions. The chapter also discusses key questions and indicators for assessing the effectiveness of technology.
