This and other terms show the specificity expected whilst engaging in investigations that are science oriented.
1) question asking and problem definition: during scientific investigations, students should always be able to ask questions on underlying issues. In engineering cases, the questions should be so as to solve certain problems and aid in ideas. Questions should involve such steps as data collection, claims and designs.
2) development and use of models: NRC Framework (2012, p 58) indicates various steps in modeling ranging from simple/physical to abstract. models represent scientific systems under scrutiny and assist in answering some queries or raising ideas to be developed. models can also aid in developing data that is important in making essential contributions as well as for communication purposes. When models are compared with expected objects iteratively, they assist in bringing insight to the idea under development.
3) investigations: in the K12 years, it is essential that students get the chance to plan investigations and eventually carry them out. these should range from teacher-prescribed to personal ones. investigations in fields of science are mainly to test theories or for descriptions whilst in engineering, they are used to check on systems. in taking investigations in either of the fields, it is advised that the students should have preset goals. More so, the students should ensure that they support whatever they are claiming by providing data as proof.
4) Data Analysis and interpretation: data makes logical sense when it can show relations that can lead to a subsequent analysis of results. Therefore, raw data should be scientifically worked on in the desired way for it to be of help. This assists the scientist or the engineer to use the data as evidence. This practice is important to both scientists and engineers as both fields require evidence in practice. For an engineer, for example, properly analyzed ...Show more
