Question 1
1.1 Meaning of Technology Technology refers to the application of scientific
knowledge for practical purposes to solve problems or improve human life. Examples
include smartphones (communication), agricultural machinery (farming efficiency), and
solar panels (energy production).
1.2 Role of Indigenous Knowledge Systems (IKS) IKS contributes to technology by
providing traditional solutions to modern problems. For example, using natural materials
for construction or herbal remedies in healthcare demonstrates how traditional
knowledge informs sustainable, context-specific innovations.
1.3 Key Steps in the Design Process
1. Identify the problem: Recognize and define the issue to be solved.
2. Investigate: Gather information and research possible solutions.
3. Design: Develop possible solutions and choose the most effective one.
4. Make: Construct the chosen solution using appropriate materials.
5. Evaluate: Assess how well the solution solves the problem and refine it.
1.4 Conceptual Knowledge in Technology Education Conceptual knowledge refers
to understanding principles, theories, and ideas behind technological concepts. It is
essential as it enables learners to apply knowledge flexibly and creatively in new
situations.
1.5 Significance of IKS for Modern Engineering and Design IKS offers sustainable,
locally relevant solutions, enriching engineering practices with alternative perspectives,
such as eco-friendly architecture or traditional irrigation systems.
1.6 Historical Development of African Metallurgy African metallurgy dates back over
2000 years, including advanced iron-smelting techniques in places like Nok (Nigeria)
