The filmstrip projector was introduced into the world of education in the 1920s. It served as the first audio-visual aid used in the classroom. It replaced the use of radio as the main technological piece used in schools. The use influenced education to the age of visual awakening, with images being projected in classrooms for the first time. The educational theory could now include a vast array of visual images from a film instead of drawings, maps, or posters. The initial use of film would influence the sector to advance technology in the next few decades.

The photocopier was introduced into schools in the 1950s. With its invention, copies for the entire class could be made quicker and easier than before. Documents used to be made with ink and pressed onto a blank sheet of paper. Education was influenced by the ability to copy more documents than what was possible before. This technology played a role in the evolution of teachers sharing intellectual property. With a photocopier, teachers could distribute and share more documents than ever. The milestone influenced education practice, with teachers having more options for printing papers and visual aids in the classroom.

The overhead projector was implemented into education in the 1960s. It was an evolution from previous filmstrip projectors but with larger film transparencies. Transparencies allowed teachers to annotate and write on top of the editing information. The incorporation influenced the evolution of educational technology, with teachers being able to modify and add to the printed material that was projected. Transparencies influenced educational practice as they could be mass-produced and sold to schools in bundles of pre-created curricula. Having manipulatable slides helped to reduce the time used to write on a blackboard or create commonly used images like a graph.

The use of calculators in schools has had an impact on how students complete calculations. Small pocket size calculators were brought into schools by Texas Instruments in the 1970s. With calculators, students can spend less time on calculations and more time on ideas and content. Besides doing simple calculations, Kissane (2017) suggests calculators can be used intelligently to increase development and understanding. Calculators can be used to understand more difficult aspects of math when not simply used as a device to obtain answers. The deceives changed educational practice because they were primarily used in schools to eliminate the need for printed tables to obtain calculations accurately and quickly. They play a role in the editioning of educational technology as they shaped how manufacturers would create the devices to accommodate math taught in schools which now have the ability to derive and plot functions.

The invention of the VCR allowed for videos to be replayed in the classroom and replaced traditional film projectors in the 1980s. Until this time, live television was a method of viewing video in the classroom, but it could not be recorded or rewound like film projectors. The invention influenced educational theory with videos having the capability to explain ideas quickly and efficiently when compared to text. Laparra et al. (2022) explain that the use of moving images also allows for the use of visual perception. Students can also observe how scientific phenomena occur without being there. Results from the studies suggest that there is a positive correlation between visualized videos and academic achievement. The educational practice was also significantly impacted, with teachers now having the option to show a video of an event or phenomenon instead of storytelling.

The first interactive smartboard was introduced in the 1990s, replacing traditional projectors. With this change, anything from the computer could be placed on the screen. Smartboards were invented for an additional touch-capable interactive display. Murat & Bulenet (2021) suggest the use of smartboards has advantages by increasing interaction among students. Increased instructiveness can positively affect students' motivation and allow for a more diversified learning experience. Education with the use of technological tools allows for learning to become permanent. Above all, the use of smartboards allows students to use their imagination with visual imaging to reinforce subjects and ideas in their minds. With smartboards, students would line up to calibrate it or be the next ones in line to use the digital marker.

The first use of electronic books or E-texts was introduced to education in 2003. The advantage of offering books online is that it saves money from printing. The milestone influences education in the amount of material that is available at a click. Digital texts cost less than printed books and require no storage. The evolution of educational technology would move to make user interfaces more usable in order to accommodate electric learning. Educational theory was changed by the amount of learning that could now be done solely on the computer. Novak et al. (2018) assert that the creation of e-texts is seen as an integral part of twenty-first-century learning. Learning now has the portability to be anywhere with the internet and change the way students perceive and interact with the text. Educators had to adapt their practice to reading and learning from an electronic platform can requiringstudents to possess different fundamental skills and abilities and literacy skills.

The most modern change in education accorded in the 2010s with eh introduction of iPads and Chromebooks as 1:1 devices. The use of these devices by every student completely changes education theory and practice. Much of today’s teaching process is dependent on students having access to a device. In addition, many skills of using, typing, and creating on 1:1 devices are an integral part of the curriculum. Domjanic Drozdek et al. (2020) explain devices alter the teaching and learning process and increases engagement with individual and group activities. Students are able to use the internet, download, create, and share virtual videos, labs, and experiences. Education technology was completely revolutionized as manufacturers and districts realized the necessity of providing cost-effective devices for every student.
