PRODUCTION OF 3D SCIENTIFIC INSTRUCTIONAL MODELS USING “ENDER 3 NEO” 3D PRINTER

Öz

It is generally believed that pupils and students understands and assimilates better when taught using concrete physical objects. The problem of lack of understanding of the teaching of scientific concepts especially in the secondary schools is partly because the teachers do so using abstract concepts in teaching science subjects. What a child have not seen before and it is taught without the provision of such object is likely to cause confusion in the mind of such student. This is where using concrete object becomes important and so the objective of this study is to produce scientific models like skull, eye, brain and skeleton for pedagogic purpose. Although the 3D technology has gained significant recognition worldwide for its ability to produce sundry equipment, there is limited awareness in developing economies like Nigeria and other African countries; so this study aims to explore the potentials of 3D printing technology in the production of sundry scientific equipment for teaching. The methodology used in this research is studio-based and practice-led where 3D printer was used in the studio to produce sundry models and apparatuses to precision. The models so produced are to be sent to secondary schools for testing and at the end it was found that teaching with physical objects enhancing understanding.
