NYSTCE Technology Education key terms

The purposeful application of knowledge, tools, materials, and systems to solve problems and extend human capabilities; it includes the products, processes, and knowledge created through engineering and design.

The ability to understand, evaluate, and use technology responsibly; it includes knowledge of how technology works, its effects on society, and skills for informed decision-making about technological issues.

An approach that views a problem as a set of interconnected parts whose interactions produce behavior that cannot be understood by examining the parts in isolation.

The process of turning an idea or invention into a practical product, service, or method that is adopted and used; innovation includes incremental improvements as well as radical breakthroughs.

The creation of a new device, process, or method that did not exist before; an invention may remain unused until innovation and adoption bring it into practical application.

Meeting present needs without compromising the ability of future generations to meet their own; in technology, it involves considering environmental, social, and economic impacts across a product's life cycle.

A systematic method for evaluating the environmental impacts of a product or process from raw material extraction through manufacture, use, and disposal or recycling.

A design or business strategy in which products are intentionally made to become outdated or unusable after a set period, encouraging replacement; it raises ethical, environmental, and consumer concerns.

The gap between groups that have reliable access to digital technologies and the skills to use them and groups that do not; it affects education, employment, and civic participation.

The movement of technology, knowledge, or methods from one setting to another, such as from research laboratories to industry or from one country to another; it involves adaptation to local conditions.

Technology designed to fit the resources, skills, culture, and needs of a particular community, often emphasizing affordability, maintainability, and local materials rather than maximum sophistication.

A cyclical approach to solving technical problems that typically includes defining a problem, researching, generating ideas, selecting a solution, building a prototype, testing, and iterating based on evidence.

A concise written statement that defines a design problem, its target user, goals, constraints, and criteria for success; it guides the team and helps evaluate whether a proposed solution meets requirements.

Limitations or restrictions on a design, such as budget, time, materials, safety rules, physical laws, or user needs; constraints shape which solutions are feasible and must be addressed during design.

Measurable standards or requirements used to judge how well a design solution meets its purpose; criteria guide decision-making and provide the basis for testing and evaluation.

An early working model of a design that is built to test ideas, materials, or performance; prototypes range from rough mockups to functional models and are refined through repeated testing.

The repeated cycle of testing, analyzing results, and revising a design; each iteration is intended to improve performance, reduce flaws, or better satisfy criteria and constraints.

A compromise in which improving one aspect of a design requires accepting a disadvantage in another, such as choosing lighter weight at the cost of strength or lower cost at the cost of durability.

Computer-aided design: the use of software to create, modify, analyze, and document two- or three-dimensional models of products and systems before they are built.

A method of representing a three-dimensional object with separate two-dimensional views, usually front, top, and right side, arranged to show true shapes and dimensions for manufacturing or construction.

A model describing technological systems as transforming inputs such as materials, energy, and information through a process into outputs, with feedback used to adjust the process and improve results.

A control system that performs actions without using feedback from its output to adjust operation; it follows a preset sequence and cannot correct for errors or changing conditions.

A control system that monitors its output and uses feedback to compare actual performance with a desired target, automatically adjusting its action to reduce error.

Information about a system's output that is returned to the system and used to adjust future action; feedback can be used for automatic control, quality improvement, or user correction.

A smaller functional part of a larger technological system that performs a specific role and interacts with other parts; subsystems can themselves be analyzed as systems.

The use of control systems and equipment to operate machines or processes with minimal human intervention; automation can increase consistency and productivity but requires careful design, maintenance, and safety planning.

Computer numerical control: the use of programmed instructions to control machine tools and manufacturing equipment; CNC allows precise, repeatable cutting, shaping, and production of parts from digital designs.

The design, construction, and programming of machines that sense their environment and perform physical tasks; robots combine mechanical, electrical, and software subsystems and are used in manufacturing, medicine, and education.

An instructional approach that combines science, technology, engineering, and mathematics concepts in coherent, problem-based learning experiences rather than teaching the subjects in isolation.

A teaching method in which students learn by investigating and responding to a complex, authentic question or problem over an extended period, producing a product or presentation.

A physical or digital space equipped with tools, materials, and technologies where students can design, prototype, and build projects; makerspaces support hands-on learning, collaboration, and iteration.

Technological pedagogical content knowledge: a framework describing the integration of technology knowledge with pedagogical knowledge and subject-matter knowledge that teachers need for effective technology-enhanced instruction.

An instructional approach that adjusts content, process, products, or learning environment to address diverse student readiness, interests, and learning profiles while maintaining high expectations for all.

Ongoing assessment used during instruction to gather evidence about student learning and provide feedback that helps students improve before a final evaluation.

Assessment conducted at the end of a unit, course, or project to measure what students have learned and assign a grade or determine proficiency against standards.

An assessment in which students demonstrate knowledge and skills by completing a realistic task or producing a product, often judged with a rubric that describes levels of quality.

A scoring guide that lists criteria for evaluating student work and describes levels of performance for each criterion; rubrics make grading more transparent and consistent.

Safety data sheet: a standardized document providing information about a hazardous chemical's properties, health effects, safe handling, storage, and emergency procedures; employers must make SDSs accessible to workers and students.

Personal protective equipment: equipment worn to reduce exposure to hazards, such as safety glasses, gloves, aprons, and hearing protection; PPE is a last line of defense and must be selected for the specific hazard.

Physical barriers or devices that prevent people from contacting dangerous moving parts of machinery; guards must be in place during operation and must not be bypassed.
