Scientific Method (used in science) and
Invention Method acting (used in engineering,...)
by Craig Rusbult, Ph.D.
I.O.U. — Soon, but probably not beginning until late 2011,
I'll write a star revision of this page. Currently you can see a summary of
the main ideas (but this Page volition go beyond them with further geographic expedition) in
An Institution to Design
so I advocate that you read information technology now. Then you can recall to this page,
simply skip Section 1 and move onward to Sections 2 and 3.
I.O.U. — What you visit below (in the table and turquoise ink ) are unkind-draft components that might exist secondhand as part of the major revision described to a higher place.

comment for reader: Sections 2 & 3 will be altered by the end of 2011, but they mightiness be worth reading now.
Shortly (hopefully in late-August 2011) a new part of this subdivision will fulfill the I.O.U. from Problem Solving and Metacognition in Education.
• Design Method and Scientific Method: A compare of my models for Mainstreamed Design Method and Integrated Technological Method shows that, as explained in Skill and Blueprint [which links to the section you're now reading], when students use Design Method acting they already are using whol of the principal components of Scientific Method: during design they have been Choosing Objectives & Goals, Searching for Relevant Information, Predicting and Observing so they can use Reality Checks to Evaluate Theories, Creatively Generating Ideas for Theories & Experiments away exploitation Retroductive Logical system, and Making Military action-Decisions. These overlaps wish let them learn Knowledge domain Method much more easy, due to a transfer of ideas-and-skills from design to science.when students manipulation Design Method they already are using all of the main components of Scientific Method: during design they have been Finding Info, Predicting and Perceptive so they can use Reality Checks to Evaluate Theories, Creatively Generating Ideas for Experiments & Theories by using Retroductive Logic, Choosing Objectives & Goals for a Trouble-Resolution Project, and Making Action-Decisions. These overlaps leave let them learn Technological Method much more easily, due to a transfer of ideas-and-skills from design to science.
Present are photo-reduced diagrams for Blueprint Method & Knowledge domain Method, which will be compared here in mid-August:
comment: Below here is the old depicted object, which will beryllium radically condensed-or-cut and revised in August.
In the ii sections below (2 and 3) we'll get down with summaries of process (in technological method and design method) before moving into comparisons of science and plan.
2A. The Process of Science
In scientific logic, as in day-to-day life, you use reality checks to decide whether "the way you think the populace is" corresponds to "the way the direction the world in truth is." ... A physical try out allows observations of what nature actually does, and a mental experiment lets us make predictions about what nature bequeath do. In a world check, scientists compare OBSERVATIONS with THEORY-based PREDICTIONS. If a theory fails in a reality check because its predictions do not lucifer observations, scientists prat turn away the theory. ... Most philosophers call back that, according to formal logic, we cannot prove a theory is either true or false, but we can develop a rationally even confidence in our conclusions. .....
The diagram below has three main elements: OBSERVATIONS, PREDICTIONS, and THEORY. If you study the diagram and the summary above, it should make sense. Notice the arrows pointing away from possibility (because a theory is secondhand for making predictions, as explained above) and toward theory (because observations are used to generate a theory, as explained below).
2B. The Process of Design
The opening move in solving a job is recognizing that it exists. You recognize a problem when you understand the way a situation is now, and you stool imagine a future in which things deliver changed and built. Or maybe you can imagine a incoming in which things have changed but cause non developed, and you privation to avoid these changes. Either direction, if you want to take advantage of your chance to make a difference, you will generate and evaluate ideas-and-actions that avail you make progress toward solving the problem.
Envisage that you are difficult to pattern a product, and your total objective is "an developed refrigerator."
You define your quality-GOALS by defining the coveted properties of a hunky-dory product. In this case, what kind of "improvements in the refrigerator" do you want? Your goals are settled on your knowledge of what is, and your imagination about what could be.
Usually, the search for a resolution begins by remembering old products, by probing your own memory and our collective memory (in books, websites,... and in other people) for existing products. For each old ware, you collect OBSERVATIONS of the product's properties, and ask "How closely do these known properties match my goals for the properties of a satisfactory product?" In this question, you are comparing observations with goals in a quality-check that lets you determine how substantially a product meets your superior-goals, which are your criteria for defining quality.
You hind end widen your range of options by imagining new products. Unremarkably, a new product is invented when, guided by goals, you begin with an used product and progress to changes. Based connected what you know approximately the old ware and bran-new changes, you john do mental experiments to predict the properties of a new merchandise. Or you can foreshadow the properties of an honest-to-god merchandise in a new situation. In either case, you use your PREDICTIONS past asking "How close do the predicted properties match my quality-goals?" In this quality-check, you are comparison predictions with goals.
You stool also gain knowledge by testing a intersection (grey-haired or virgin) in a somatogenetic experiment that lets you make OBSERVATIONS about properties. And so you crapper involve, "How tight do the known properties match my quality-goals?" In this quality-check, you are comparing observations with goals.
Design Decisions: You use choice checks (by comparing quality-goals with observed properties or predicted properties) to evaluate each voltage product, old operating theater new. Eventually, you may find a product that satisfactorily achieves your goals, and you think the problem solved. Or you continue searching, Beaver State abandon the search.
The very process of action mechanism-and-logic is used for designing a product or strategy. But the process is different for designing a hypothesis in science.
The plane section beneath compares science with its closest cousin in design, which is engineering.
3. Comparing Design and Scientific discipline
If we define design as the design of products or strategies, and science as the designing of theories, how are design and science related? What are the similarities and differences, in cognitive process and intention? The independent actions-and-logic used in hypothetico-deductive Reality Checks (for design and science) are summarized in these tierce diagrams:
And for a more detailed description, check the lower part of this diagram.
I.O.U. — Before long the upper contribution of this diagram also will be described in this page, in a subdivision about
the relationships between my models of Integrated Design Method and Integrated Scientific Method.
DESIGN Method acting: During the process of design, you set quality-GOALS for wanted properties, use somatogenetic experiments to nominate OBSERVATIONS, and consumption mental experiments to constitute PREDICTIONS, so you can do QUALITY CHECKS either by comparison observations (of known properties) with goals (for desired properties) or by comparing predictions (of expected properties) with goals (for desired properties). If you wish to understand design method finer, examine the diagram and this brief summary to beat an overview of "the big picture" and then re-read the previous section about The Logic of Pattern.
SCIENTIFIC Method: During the process of scientific discipline, American Samoa explained earlier and shown in the diagram, OBSERVATIONS (from somatic experiments) are used to imaginatively get a THEORY, which can be used with if-then logical system (in a psychogenic experiment) to make PREDICTIONS, so you can coiffe a REALITY CHECK by comparing observations with predictions, to prove whether "the way you think it is" (assuming the theory is true) corresponds to "the way it really is."
Comparing Process: The methods used in science and design are related, yet different. The three elements of thinking — goals, observations, and predictions — can be compared in three ways. Cardinal comparisons (of observations with goals, and predictions with goals) are used in design for quality checks. One comparison (of observations with predictions) is put-upon in scientific discipline for a reality check.
Comparing Desig: In design, the main representational is to develop a mathematical product or strategy, to invent or improve something that is humanly constructed. In science, the main concrete is to develop theories, to understand nature.
Comparing Process-and-Purpose: In design , we exercise choice checks to resolve whether a particular product (or scheme) satisfactorily achieves our quality-goals for the intersection (or scheme). In science , we use reality checks to test whether a possibility corresponds with realism, whether it is true. The serve is contrastive because the purpose is different.
Comparison Overlaps: Much, the results of scientific discipline behind be applied in the design of products operating theater strategies, merely this is not the main objective of science. During design it may be useful to ameliorate a hypothesis that is being used while nonindustrial a production or strategy, but possibility ontogenesis (which is the main object glass in skill) is non the main objective in excogitation.
Comparing Cousins: Although it can be interesting to compare science with a wide range of design Fields, it seems near immediately effectual to comparability scientific discipline with its nighest cousin in design, which is engine room. Comparing objectives, we regard that science tries to understand nature, while engineering tries to improve technology. Placard the deuce differences: apprehension versus improvement, and nature versus technology. But there are also similarities, interactions, and overlaps. The understanding gained by skill is often applied in technology, and science often uses engineering, especially for making observations only also in unusual shipway. Sometimes in scientific discipline or engineering — e.g., when we try to understand the chemistry and physics of combustion in automobile engines — we study the behavior of nature in the linguistic context of technology. And because the definitions we'Re using mark between scientific discipline and conception on the cornerston of purpose-and-process (objectives-and-methods), not careers, a man of science sometimes does engineering, and an organize sometimes does scientific discipline.
comment to reader: This section volition have a John R. Major revise, by including much ideas from the same set forth of An Introduction to Blueprint and more or less ideas (those that are near interesting and relevant, but not the esoteric "scholarly" analysis) from Design and Science (Part 2).
4. Many
The main desig of this page is to compare design and skill, to find and the similarities and differences in objectives and methods (in purpose and process).
These ideas, and others, will comprise explored more deeply in a follow-up page — During this exploration, a few of the many unputdownable questions are:
1. How should we define science and engineering? Should we focus on functions (such every bit objectives and methods) or careers (by defining science as whatever a scientist does, and technology as whatever an engineer does)?
2. Is "applied scientific discipline" (however this is defined) more similar to science Beaver State applied science?
3. In each discipline, how should we purview the contributions of experimentalists (World Health Organization produce observations) and theoreticians (World Health Organization interpret observations)?
4. Suffice approximately masses think the goal of science is non (or should not be, or cannot be) a hunt for truth?
In education, wherefore should we Blackbeard Design ahead Skill, and how can reality-checks make up used as a bridge from design to science?
The reexamination page is onymous, as you might expect, Design and Skill (Parting 2). Even though it is "under construction" and is only partly finished, it contains both ideas that you may find interesting and useful. Currently, the main sharpen is Question #1, and my claims for the potential time value of an Objectives-and-Methods a priori approach that is based on "the similarities and differences in objectives and method" in design and scientific discipline. / I.O.U. — Roughly of Part 2 (but not the more esoteric parts) will Be moved into the terminate of this page, equally part of the MAJOR REVISION described at the superlative of this page.
