Teaching, it is said, is a thankless job. And yet, it is also a job that comes with power like no other. Moulding and shaping young minds becomes the primary responsibility of teachers. Every generation of youngsters is determined by the generation of teachers that came before them. The difficulty of teaching lies primarily in the ability to grasp the attention of students. A teacher who can get the students to listen with interest has already completed half the job of education.
While this ability to get the students’ attention depends mostly on the teacher’s innate capabilities, it can also be aided with the help of technological advancements, especially like the innovative process of 3D printing. Teachers can use 3D printing to make models that students can actively touch and feel, making the entire process of teaching so much more interactive. When the students are engaged, all teaching becomes a lot easier. And this is not limited to teachers of a certain subject or certain level.
3D printing proves to be useful in teaching at all levels of education- elementary school, high school, and even colleges and universities. Elementary school teachers can make use of 3D printed models to explain geometry, artwork, and even geography. These models become especially useful when teaching high school science and social studies. Geographical maps become so much easier to understand when they can be approached from an objective, hands on way. Science subjects like chemistry and physics can be explained through models of levers, atoms and molecules, instead of pictorial representations on a blackboard. Even biology seems much more interesting when the students can hold a model of the heart in their hands, instead of just studying it from a textbook that depicts its cross-section.
University professors can also engage in effective teaching in nearly every field. Teaching engineering students the intricacies of a machine can become much easier when they can all examine models of the parts. Teaching architecture and graphic design students can be simplified many times over. Even teaching medicine can be made much more cost-effective and interactive with the help of 3D printing resources.
Teachers could be both a promoter and a barrier for such innovative technology in the advancement of education. While most teachers may embrace these new techniques, there could be some who may have attitudes and beliefs that may prevent them from readily accepting the use of 3D printing in everyday teaching. However, when sufficient guidance is given to the teaching community and they are trained to use this technology with ease, it can only be an asset in their hands.
