Evolution of technology in teaching: Blackboard.

In the final project we have to use at least three technological elements. Consequently I want to share with you the evolotion of technology in teaching. Blackboard is one of the elements that people used since early times. I am going to tell about the types and evolution of blackboard. 
Teaching and learning, which is the passing of knowledge from one generation to another, has been in existence from the earliest times of human civilization. It began in 1801, with a large piece of slate hung on the wall in a school in Scotland to provide information to a large audience at one time. Meanwhile in the US by mid-19th century, every class room had a blackboard to teach students. The modern version of the blackboard is either green or brown board. On the other hand the whiteboards came into use during the late 1980s.

The teaching boards

The need to provide information to a large audience at one time led to the evolution of teaching boards. The whole class or group of students can visualize the information provided on the board. Globally, the classrooms of universities, colleges and schools use blackboard, green board, white board (dry-erase board) or the smart boards.

Blackboard:

 The use of the blackboard by a teacher depended on his/her ability to draw and write on the board. It provided variety of opportunities for modifying the presentation of the subject content. The introduction of blackboard was a new innovation that was well accepted by the teachers and it gained popularity across the globe.

Greenboard and Brownboard:

The modern version of the blackboard is either green or brown board. This was introduced in late 1960s. These boards were steel plate coated with porcelain-based enamel, which could be used for a long time.

Whiteboards:

The whiteboards or dry-erase boards came into use during the late 1980s. They have a glossy-white surface for writing. Instead of chalk pencils, whiteboard pens were used to write on whiteboards. Considering the health reasons and cost-effectiveness, by 1990s most of the class rooms were replaced with whiteboards instead of blackboards.

Interactive Boards:

Interactive boards are connected to a projector which connects with a computer or laptop. The interactive whiteboards can be mounted on to walls and used in any setting. Towards the end of 2000, the Smart Board came into existence. It is like a dry-erase board that does not use pens to mark on it. It has a projector that puts the image on the board
