This objective is assessed through direct observation of the student's practical abilities during construction and by examining the finished prototype. Students will exhibit proficiency in:
- Accurate Cutting: Achieving clean, precise cuts according to marked lines and dimensions.
- Precise Shaping: Skillfully forming materials to achieve the intended curves, angles, and contours, especially those related to ergonomic features.
- Secure Joining: Competently connecting different parts of the prototype using appropriate techniques (e.g., effective use of adhesives, tabs, slots, fasteners) to ensure the prototype holds together and maintains its form.
- Attention to Detail: Evidence of care and precision in the overall construction, resulting in a prototype that clearly represents the chosen design idea.
- Safe Handling: Consistently demonstrating safe practices with tools and materials.
Detailed Explanation
In this chunk, the focus is on the level of technical skills a student is expected to demonstrate while constructing their prototype. This includes five key areas:
1. Accurate Cutting: Students must be able to cut materials carefully, following pre-marked lines to ensure precision and clean edges.
2. Precise Shaping: The materials need to be formed into the required shapes, curves, and contours that align with ergonomic design principles.
3. Secure Joining: Students should know how to join different parts of the prototype securely using various methods, ensuring that the assembly is robust and stable.
