The scientific method is an empirical method for acquiring knowledge that has characterized the development of science since at least the 17th century (with notable practitioners in previous centuries; see the article history of scientific method for additional detail.) It involves careful observation, applying rigorous skepticism about what is observed, given that cognitive assumptions can distort how one interprets the observation.
Technology education is the study of technology, in which students "learn about the processes and knowledge related to technology". As a field of study, it covers the human's ability to shape and change the physical world to meet needs, by manipulating materials and tools with techniques. It addresses the disconnect between wide usage and the lack of knowledge about technical components of technologies used and how to fix them. This emergent discipline seeks to contribute to the learners' overall scientific and technological literacy, and technacy (see ).
Research is "creative and systematic work undertaken to increase the stock of knowledge". It involves the collection, organization and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion on past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole.
