Slate boards were among the earliest reusable writing tools in classrooms. Students wrote on individual slate boards with chalk, which could be wiped clean and reused. This was revolutionary for its time as it conserved paper (which was expensive) and allowed students to practice writing and arithmetic without wasting resources. Slate boards remained the primary instructional tool in classrooms throughout most of the 19th century.

The first chalkboards (or blackboards) came into widespread use in schools. While earlier versions existed, it was in the 1840s that they became standard in classrooms across the United States and Europe. This innovation transformed teaching by allowing instructors to present information to an entire class simultaneously rather than working with students individually. Invented by James Pillans, a Scottish teacher, the chalkboard would remain a classroom staple for over 150 years, famously leading from chalk use to the incorporation of ink-based technologies.

The Remington No. 1, the first commercially successful typewriter, was introduced. While not immediately adopted in classrooms, typewriters eventually became essential tools for teaching business skills and composition. By the early 20th century, typing classes became standard in many high schools and colleges, preparing students for office work and professional writing careers. This gradually transitioned into the use of computers for typing and composing information digitally.

Educational films began to be widely used in schools. The introduction of 16mm film projectors made it feasible for schools to show educational content to students. Thomas Edison, who had predicted in 1913 that books would soon be obsolete in schools due to motion pictures, was partially vindicated as film became an important supplementary teaching tool. These early educational films covered topics from science to geography and history.

The mimeograph machine gained popularity in schools, allowing teachers to create multiple copies of worksheets and tests. This technology, which used a stencil and ink to reproduce documents, revolutionized how materials could be distributed in class. For the first time, teachers could easily create customized materials for their students without relying solely on textbooks. The distinctive purple ink and smell of mimeographed papers became a memorable part of the school experience for generations of students.

Overhead projectors became standard in many classrooms. Originally developed for military training during World War II, these devices allowed teachers to write on transparent sheets while facing the class - a significant improvement over chalkboards. Teachers could prepare transparencies in advance, overlay multiple images, and reveal information progressively. This technology remained a classroom staple through the 1990s.

Programs like 'Sesame Street' (launched in 1969) and educational television initiatives transformed learning. The Public Broadcasting Service (PBS) in the United States and similar services in other countries began producing high-quality educational content specifically designed for classroom use. Television brought expert presentations, visual demonstrations, and engaging content into classrooms across the world. The Children's Television Workshop (now Sesame Workshop) pioneered research-based educational media that would influence educational technology for decades to come.

The introduction of affordable personal computers like the Apple II (late 1970s) and IBM PC (1981) began to transform education. Schools started establishing computer labs and introducing computer literacy courses. Educational software companies developed programs for math, reading, and other subjects. Early educational software like 'The Oregon Trail' and 'Where in the World is Carmen Sandiego?' combined learning with gameplay. The Logo programming language, developed by Seymour Papert at MIT, introduced students to computer programming concepts.

The World Wide Web became accessible to schools, opening up unprecedented access to information. Educational initiatives in many countries prioritized connecting classrooms to the internet. Teachers and students gained access to online encyclopedias, research databases, and global communication tools. Early educational websites began offering lesson plans, interactive activities, and resources for teachers. This decade marked the beginning of digital literacy becoming an essential educational outcome.

Interactive whiteboards, such as the SMART Board (introduced in 1991 but widely adopted in the 2000s), combined the traditional whiteboard with computer capabilities. These tools allowed teachers to display computer content, manipulate digital objects through touch, save notes from class sessions, and incorporate multimedia elements into lessons. They represented a significant advancement in making technology interactive for whole-class instruction.
