Practice of Learning Method of Properties of Wood and Wood-Working Methods for Elementary School Children: Through the Production of a Puzzle and Storage Case
This study describes a course for acquiring knowledge and skills in the properties of wood and wood-working methods in an elementary school manufacturing class. A puzzle and its storage case were produced during this course. Knowledge and skills about the properties of wood and wood-working methods were added during each manufacturing process. Teaching materials were used to explain the materials used in the production of the puzzle and case; i.e., the fiber direction and strength (anisotropy of strength) of wood and the diff erence between wood and plywood (structure and strength of plywood). The external features of wood (fiber direction, grain, tree rings, cross-grain surface, end-grain surface, sap side, heart side, and edge grain surface) were explained during the correct assembly of the puzzle pieces. Methods for the safe use of hand tools (e.g., ruler, double-edged saws, clamp, gimlet, sandpaper, adhesives, and screwdrivers) in each wood-working process were explained. The results of the questionnaire showed that many participants acquired wood-working knowledge and skills, but their ability to use their knowledge about the properties of wood could not be learned.
