Technology Through the Decades Technology has come a long way since the institutionalized first classroom. The limits to progress have only been greatest in the last 100 years. But the class we know today in American culture has made many adjustments and achievements over many centuries of work, but this article will only address the last 2 centuries. The modern classroom, with computers, the Internet, graphing calculators, and video devices, would not exist if it were not for the many people who worked to invent the machines we have. The 1800s produced many advancements in the classroom that, while very rudimentary by today's standards, became the basis for large-scale learning. Some of which are still in use today. In 1841 the blackboard was introduced into school classrooms. This was very helpful for learning by integrating audio and visual techniques into learning. Teachers could now draw for students concepts such as atoms and molecules, which were complicated to express. The students found this invention beneficial because they now knew what the teachers were saying, what the key points were that they needed to know and nothing was lost in the communication. The inclusion of radio in the 1920s (Studio Miramar) was also a beneficial invention. When radio was invited to be part of classroom learning, teachers were able to more effectively keep students updated on current events, engage others' opinions or knowledge of different topics, and be able to include culture in history lessons. This last reason would become the basis for expanding the curriculum to a multicultural level. Another major change to the curriculum came in the 1940s when films became part of the school scene (Studio Miramar). This has had an impact both politically and with general education. Politically, propaganda or reprogramming with videos would be a purpose that films would serve. With films like those expressing how the "proper American" should behave, such as during World War II with "Duck and Cover" or "Evil Communist" or even "Uncle Sam Wants You", videos became a significant nationalist method. to reach children. But films also play the role of an educational tool. Films about chemicals, their dangers and benefits, or safety films such as “Stop, Drop, and Roll” became prevalent. Like radio, television, introduced in the 1950s into the educational scene (Studio Miramar), has become an even easier method of keeping students updated on current events.
