One of the pioneers of programmed learning was Sidney L. Pressey, an American psychologist who developed the first programmed learning system in the 1920s. Pressey’s system, known as the “Self-Teaching Machine,” used a series of questions and answers to guide learners through a structured learning process. However, it was not until the 1950s that programmed learning gained widespread attention, thanks to the work of Benjamin Bloom and his colleagues at the University of Chicago.

Bloom and his team developed a programmed learning system called the “Mastery Learning Program,” which was designed to help students learn at their own pace by providing them with immediate feedback on their progress. The system consisted of a series of instructional materials, including textbooks, workbooks, and audiovisual aids, that were carefully sequenced to ensure that learners progressed through the material in a logical and systematic manner.

Another key figure in the development of programmed learning was Frank L. Keller, who developed the “Keller Plan” in the 1950s. The Keller Plan was based on the idea that learners could learn more effectively if they were given a series of problems to solve, rather than simply being presented with information. Keller’s approach was groundbreaking because it recognized that learners needed to actively engage with the material in order to learn it effectively.

The development of programmed learning had a profound impact on education, as it helped to shift the focus of learning from memorization and passive reception to active engagement and problem-solving. It also demonstrated the potential of technology to transform the learning process, laying the groundwork for future advancements in educational technology.
