* Identifying and defining problems: Students learn to identify real-world problems that could benefit from a technological solution. This involves research, observation, and understanding user needs.
* Brainstorming and ideation: Generating many possible solutions, exploring different approaches, and considering various constraints (time, budget, materials, etc.). Techniques like sketching, mind mapping, and prototyping are commonly used.
* Research and analysis: Investigating existing technologies, materials, and processes relevant to the design challenge. This may involve researching scientific principles or conducting user interviews.
* Design and modeling: Creating detailed designs using software (CAD, 3D modeling), sketches, diagrams, and physical models. This stage focuses on refining the chosen solution and ensuring it meets the specified requirements.
* Prototyping and testing: Building working models (prototypes) to test the design and identify areas for improvement. This is an iterative process; designs are often modified based on testing results.
* Evaluation and iteration: Analyzing the performance of the prototype and making necessary changes. This might involve user feedback, data analysis, or simulations.
* Documentation and presentation: Creating detailed documentation of the entire design process, including design choices, challenges encountered, and final results. This often includes presentations to communicate findings and justify design decisions.
Depending on the class, students might use a variety of tools and technologies, including:
* Computer-aided design (CAD) software: For creating 2D and 3D models.
* 3D printers: For creating physical prototypes.
* Electronics components and circuits: For building electronic devices.
* Programming languages: To create software or control hardware.
* Hand tools and machinery: For crafting physical prototypes.
* Collaboration tools: For teamwork and communication.
The overall goal is to develop students' problem-solving skills, critical thinking, creativity, and ability to work collaboratively to design and create technological solutions.
