Educational technology

Educational technology, often called edtech, includes computer tools, programs, and ideas about how people learn and teach. It helps make learning and teaching easier and more fun. When people talk about EdTech, they usually mean the companies that make and sell these tools.

Edtech uses ideas from many different subjects, like how people talk to each other, how children learn, and how computers work. It covers many areas, such as learning with computers, learning online, and learning using phones or tablets.

This kind of technology helps teachers share their knowledge in new ways and helps students learn in places and times that might be hard with regular school lessons.

Definition

The Association for Educational Communications and Technology says educational technology is the study and careful use of tools and ways to help people learn and get better at things. It means planning, making, using, and checking these tools and ways for learning. Educational technology is not just about gadgets; it also includes ideas and methods to teach and learn in better ways.

Educational technology can mean many things. It can be the ideas behind teaching, the tools we use like online courses, or systems that help manage learning. It also includes ways to organize training and keep learning information. People who work in this area are called educational technologists. Today, technology is very important in schools. There are many ways to learn online, through multimedia, and using computers. Even though these tools and methods have many names, they all work to make learning better and more flexible.

History

Helping people and children learn in easier, faster, and more accurate ways goes back to very old tools, like paintings on cave walls. Simple tools such as abacus, writing slates, and blackboards have been used for many years. Books have always been important for learning. In the early 1900s, educational films and mechanical teaching machines were introduced.

In the 1960s, professors at Stanford University used computers to help elementary school students in California learn arithmetic and spelling. Online learning began in 1960 at the University of Illinois. By 1982, the first fully online master's degree was offered. In 2002, MIT started offering free online classes. Today, many students take at least one online course during college.

In 1971, Ivan Illich published Deschooling Society, imagining new ways for people to learn together. The 1970s and 1980s brought more computer-based learning tools. Videoconferencing became popular, especially for museum education.

The Open University in Britain and the University of British Columbia helped change learning by using the Internet. By 1994, the first online high school opened. Better Internet tools made learning easier and faster for students and teachers.

By 2020, many schools around the world had to close because of the COVID-19 pandemic. This led to a big increase in online learning for students of all ages. Many new technologies were developed to support distance learning during this time. Even after the pandemic, teachers continue to use digital tools more often than before.

Theory

Main articles: Educational psychology, E-learning (theory), Learning theory (education), and Educational philosophies

There are different ways to think about how people learn. One idea is called behaviorism. It started with scientists studying how animals learn, using rewards and punishments. Some famous scientists who worked on this include Ivan Pavlov, Edward Thorndike, Edward C. Tolman, Clark L. Hull, and B.F. Skinner.

Another way to think about learning is called cognitivism. This looks at how the brain helps us learn. It studies how we remember things and process information. This idea grew a lot in the 1960s and 1970s.

There is also constructivism. This says that learners build their own understanding by connecting new information with what they already know. Teachers help guide this process, letting students explore and solve problems on their own. This can include activities like working on projects or solving real-world problems.

Practice

E-learning helps students learn in many ways, from no technology to fully online. There are names for how much technology is used. For example, "hybrid learning" or "blended learning" might mean using classroom tools and laptops or spending more time learning online. "Distributed learning" can talk about online learning or fully online learning.

E-learning can happen at the same time or at different times. When it happens at the same time, everyone is together online, like in a live class or chat room. This helps students learn from each other. When it happens at different times, students can work on their own schedule. They might use emails, blogs, wikis, or discussion boards to share work.

Computer-based training (CBT) is learning on a computer or tablet, often like reading a book online. It’s good for teaching things like using software or solving math problems. CBT can include videos or animations. But making good CBT can be hard.

Computer-supported collaborative learning (CSCL) is when students work together on learning tasks. With tools like blogs, wikis, and social media, students can share ideas and learn from each other. This is different from just the teacher giving information. Collaborative learning can be fun and help students stay interested. Apps designed like games can make learning more enjoyable.

The flipped classroom is a way of teaching where students first learn at home using videos or online tools. Then, in class, they do more complex activities with the teacher. This can help students learn better, but it needs good internet access and can be harder for teachers to plan.

Technologies

Many tools help with learning and teaching. These include digital cameras, video cameras, interactive whiteboards, document cameras, electronic media, and LCD projectors. You can also use blogs, collaborative software, ePortfolios, and virtual classrooms together.

Computers and tablets let students and teachers visit websites and use apps. Mobile devices such as clickers and smartphones help with learning by letting students share ideas and get quick feedback. These devices can also help students with special needs improve their communication and learning.

Group webpages, blogs, wikis, and Twitter let learners and teachers share thoughts and ideas. Social networking sites help people talk about schoolwork and work together.

There are three types of whiteboards. The first kind looks like old blackboards but is white. Virtual whiteboards work like computer programs where you can write or draw. Interactive whiteboards let teachers and students write on a touch screen.

A virtual learning environment (VLE) is like a pretend classroom online. It mixes different ways to talk and share, like video, sound, and chat. Students can raise their hands, answer questions, or take tests. Teachers can let students share their screens and notes.

A learning management system (LMS) is software that helps give, track, and manage learning. It keeps track of who is in class and how students are doing. Teachers can post news, grade work, and chat with students. Students can turn in work, answer questions, and take quizzes.

Other tools include iPads, Chromebooks, laptops, and digital textbooks. There are also special tools for music, art, and math.

Standards and ecosystem

Learning objects

Content and design in learning have many parts. One way to think about it looks at five ideas:

• Fact – special details (like symbols in a math formula, or parts of a learning goal)
• Concept – a group with many examples (like math formulas, or different learning designs)
• Process – a series of steps or actions (like how a computer program works, or steps in a learning plan)
• Procedure – a list of steps to follow (like putting numbers into a program, or steps in a learning step)
• Strategic principle – a way to do something using rules (like making a plan in a program, or using a guide to build a learning space)

Artificial intelligence

People have studied and created artificial intelligence since at least 1956. Early uses of AI in schools were to help students learn better by giving quick and personal help. These tools can keep students learning just above what they already know.

In November 2022, a new kind of AI got a lot of attention. Some schools were worried about students using it to do their work, but later allowed it again. While it can help teachers and students in many ways, it can also make mistakes. Teachers need training, and schools need rules to use these tools safely.

Settings and sectors

Preschool

Different kinds of electronic tools can be part of preschool life. Parents often like this, but we still need more study to understand how it affects young children.

The age when a child starts using technology, like a cellphone or computer, may depend on their development. Things like age-appropriateness, matching values, and mixing fun with learning help choose the best media.

In preschool, technology can be added in many ways. The simplest is using computers, tablets, and audio or video tools in class. There are also many tools for parents and teachers to help young kids learn with technology. Some good choices are recording their work, safe internet use, tools for children with special needs, learning apps, electronic books, and educational videos. Free and paid websites and apps target preschool learning needs, like Starfall, ABC mouse, PBS Kids Video, Teach Me, and Montessori crosswords. Electronic books let kids keep many books on one device, mixing reading with technology. Technology can also help with hand-eye coordination, language, focus, and motivation, and let kids explore new ideas. To use technology well in preschool, it should be used properly, give learning chances, include adults, and match the child’s development. This helps children with special needs, bilingual children, STEM learning, and seeing more diverse worlds.

Coding is now part of early learning, and preschool kids can learn coding skills without screens. Games and activities teach hands-on coding, getting ready for future learning. Minecraft and Roblox are popular apps used by schools that offer free or low-cost access.

Primary and secondary

Main article: Primary education

More students are using online learning, especially those who can’t attend regular schools because of health issues or parents who want to homeschool but feel unsure. Online schools let students learn safely while avoiding these problems. Online charter schools aren’t limited by place, money, or class size like regular schools.

Online learning is also growing as a help to regular classes. Students with special talents or interests use it to learn more or go beyond their grade level.

Virtual education in K-12 schooling often means virtual schools, and in higher education, it means virtual universities. Virtual schools are “cybercharter schools” with new ways to manage and teach.

Education technology can also help gifted students who feel bored. This can be done with after-school programs or technology-based lessons. 3D printing courses can also give these students the challenge they need. Université de Montréal’s Projet SEUR works with Collège Mont-Royal and La Variable on this.

Higher education

Main article: Online learning in higher education

More college students are taking online classes. Many for-profit colleges now offer online classes, but only about half of private, non-profit schools do. Private schools might join more as costs go down. Staff need training to teach online, knowing both the subject and how to use computers and the internet. Online learning is growing fast, and even top research universities now have online doctoral programs.

Big online courses for many people (MOOCs) have grown a lot but can’t fully replace college learning. Schools like MIT, Stanford, and Princeton University offer classes to the world, but not for credit. Programs like edX started by Massachusetts Institute of Technology and Harvard University offer many subjects free, with some charges for official credit. MOOCs have not changed college learning much and grew less after first expanding, but they are still used. Smaller schools use MOOCs to show off special courses.

Corporate and professional

Companies use online learning for required compliance training and updates on rules, soft skills, IT skills, continuing professional development (CPD), and other work skills. Companies with products sold far away use online learning to share news about product developments. Most company learning is done when students work on their own time and is managed through learning management systems.

Government and public

Government groups use education technology to train workers and improve skills for the people they help.

Benefits

Using technology in learning helps students practice important skills while teachers manage other tasks. It lets each student learn at their own pace, which can be very helpful. For example, in India, a big exam used online tools to offer free coaching to students, even during tough times like the COVID-19 pandemic.

Modern technology makes education easier to reach, even for people who cannot attend school regularly. Students can access lessons from home and spend more time on areas they find challenging. Schools like the Massachusetts Institute of Technology have shared their materials online for everyone to use.

Students enjoy the convenience of online learning but also value being in a classroom with others. Colleges are finding new ways to make online classes more engaging. Research shows that students often learn faster and feel more positive about classes when computers are used. They can solve problems on their own and improve their writing. Using technology also helps students work together and develop important skills.

Employers now accept online education more than they used to. Many have hired people with online degrees. Educational apps can also help students who find learning harder.

Disadvantages

Using new technology in schools can be hard. Sometimes the technology gets old quickly, and it’s not always easy to keep up. Even though many places have spent money on technology for learning, they haven’t always checked if it really helps students.

New technologies often promise to change education, like silent film, radio, and television did in the past. But these didn’t stay important in everyday school lessons. Technology alone doesn’t make learning better. It’s important to focus on how learners use technology, not just the technology itself.

Some studies show that technology doesn’t always help learning. For example, babies who watched educational DVDs knew fewer words than babies who didn’t. Using technology too much can also make it harder for students to work together and build relationships with teachers.

Using technology in learning can sometimes cause problems. Students might get distracted or find it easier to cheat. Too many digital devices can make it hard for young people to focus, as their brains get used to switching tasks quickly.

There are also concerns about fairness. Not all children have the same access to technology, which can create gaps in learning. Some people worry that collecting too much data about students through educational technology might invade their privacy.

Teacher training

Teachers need to learn how to use technology well because it helps students learn. Good training helps teachers use technology in class.

Technology changes a lot, and this can make teachers feel like they always need to learn new things. It can be hard to find the right materials for students. Having just a few training days is not enough. Experts say teachers should think about how different technologies work together and how they fit with how people talk and work as teams. Using technology can help students learn better, especially because the way people find and use information has changed a lot. This can help all students, no matter how they learn best.

Assessment

Main articles: Educational assessment and Electronic assessment

There are two main ways to check how well educational technology works: looking at the technology itself, and using the technology to check how well students are learning.

One famous example is the Follow Through project.

Teachers can use technology to see how students are doing during class (called formative assessment) or at the end of a unit or term (called summative assessment). Technology helps teachers see which students are struggling and why. For example, some classrooms use special tools where each student has a small device. Teachers ask questions, and students answer using their devices. This helps everyone see who understands the material and who needs more help.

Technology also helps with end-of-unit tests and projects. With computers, teachers can give tests that tell students right away if their answers are correct. This quick feedback helps students know how they are doing and where they need to improve. Technology also lets students show what they have learned in many different ways, like through videos or digital presentations.

Electronic assessment uses computers for testing and grading. This can include many types of tests, like multiple-choice questions or even videos of performances. Computers can grade these tests quickly, which helps teachers give students feedback faster. Some important exams, like the SAT in the United States, are now graded using computers.

Analytics

Self-assessment in education technology helps students know what they are good at and what they need to improve. This is important for setting learning goals and watching progress. One tool that helps with this is Analytics. It collects data on what students do. This data is turned into patterns and shown in graphs. This helps students and teachers see how learning is going. Learning analytics is a field that looks at student data to help learning.

Expenditure

The e-learning industry has five main parts: consulting, content, technologies, services, and support. In 2000, the world value of e-learning was over $48 billion. The industry grew fast. By 2014, the market had $6 billion in investment money. Self-paced learning made $35.6 billion in 2011. In North America, e-learning made $23.3 billion in 2013. It grew at 9% for cloud tools and learning platforms.
