STANDARDS
Standards compiled from learning activities:
International- Intl. Technology Education Association: Standards for Technology Literacy
• Category The Nature of Technology
• Standard 1Students will develop an understanding of the characteristics and scope of technology.
• Grade Range 6-8
 Benchmark HTechnology is closely linked to creativity, which has resulted in innovation.
Most inventions are inspired by perceived needs and wants- the hairbrush, for example. Other inventions are linked to developing creative ideas and the way a person uses them, not necessarily their intended use. For example, the invention of the tea bag grew out of a packaging strategy to replace expensibe tin containers. Althought teas was packaged in small silk bags to give away as sampless, some useers thought it was a new ways to brew the tea, and thus the tea bag was born. An invention can always be improved, and trying new ideas is often key to that improvement.
• Category Design
• Standard 8Students will develop an understanding of the attributes of design.
• Grade Range 9-12
 Benchmark HThe design process includes defining a problem, brainstorming, researching and generating ideas, identifying criteria and specifying constraints, exploring possibilities, selecting an approach, developing a design proposal, making a model or prototype, testing and evaluating the design using specifications, refining the design, creating or making it, and communicating processes and results.
The design process is a systematic, iterative approach to problem solving that promotes innovation and yields design solutions. To systematically seek an optimum design solution, engineers and other design professionals use experience, education, established design principles, creative intuition, imagination, and culturally specified requiremetns.
 Benchmark JThe design needs to be continually checked and critiqued, and the ideas of the design must be redefined and improved.
The design process also involves considering how designs will be developed, produced, maintained, managed, used, and assessed. As a result, multiple solutions are possible. More knowledge or competing technologies cause a design to change with time.
 Benchmark KRequirements of a design, such as criteria, constraints, and efficiency, sometimes compete with each other.
When such competition happens, trade-offs occur, and the design is modified to accommodate these requirements. Different people may choose different solutions, depending on how they weigh factors.
