This section specifies the design and manufacture of the teaching resource. The first part explores the inspiration and the significance of the teaching resource to the subject of design and communication graphics. The second section examines the design of the teaching resource and the final section describes the manufacture of the teaching resource.
3.3.2 Inspiration
The results of the research study indicated the importance of modelling to support spatial visualisation which shows that physical modelling can be used as a teaching tool to support pupils’ spatial visualisation skills in learning about abstract principles related to technical graphics. From my own personal experience, I found that the area of the oblique …show more content…
After several experiments, the magnetic whiteboard film proved to have poor magnetic attraction, so the idea was abandoned. Alternatively, Bright Mind Steel (BMS) was used to create the magnetic field because it is a ferritic material; meaning that it contains iron, which is required to create magnetic attraction and it, is widely available in light sheet material. A sheet thickness of 1mm of BMS was applied to the front of the POR using gator glue. To mitigate the steel from warping the birch plywood, they had to be clamped flat until completely set shown in Figure 3 8. Plywood is manufactured using an odd number of ‘plies’/ thin layers of wood veneer, so that the sheet is balanced to minimise warping. It was discovered that to apply a material to plywood, another material must be applied onto the reverse side of the sheet to counteract any twisting or warping. (Appendix …show more content…
The case was made from birch plywood. The box was jointed using dovetail joints because it is the strongest off all the joints, has a large gluing area, resists any tension forces and is very attractive. The dovetail joints were created using a dovetail router jig. The ends of the wood were aligned in the jig and a router with a splayed cutter removed the waste material between the tails and the pins. The box was clamped and glued together using wood glue. Royal blue baize cloth was applied to the interior surfaces of the box, to protect the POR and models from damage. The logo was designed for the top of the box to capture in essence what the teaching resource consisted of. The wooden case was finished using a water-based varnish. (Appendix
