CRITICAL THINKING IS AT RISK.

Here are some of the big reasons why:

  1. Many people believe that critical thinking should be free and that scholars qualified to teach critical thinking should do so for free. Accordingly, they do not think they should have to pay for critical thinking textbooks, courses, or other resources when there is "so much free material online" - despite how erroneous that material may be.
  2. There are many misguided academicians, and some outright charlatans, pushing forth and capitalizing on a pseudo-, partial, or otherwise impoverished concept of critical thinking.
  3. Little to no funding is designated for critical thinking professional development in schools, colleges, or universities, despite the lip service widely given to critical thinking (as is frequently found in mission statements).
  4. Most people, including faculty, think they already know what critical thinking is, despite how few have studied it to any significant degree, and despite how few can articulate a coherent, accurate, and sufficiently deep explanation of it.
  5. People rarely exhibit the necessary level of discipline to study and use critical thinking for reaching higher levels of self-actualization. In part, this is due to wasting intellectual and emotional energy on fruitless electronic entertainment designed to be addictive and profitable rather than educational and uplifting.
  6. On the whole, fairminded critical thinking is neither understood, fostered, nor valued in educational institutions or societies.
  7. People are increasingly able to cluster themselves with others of like mind through alluring internet platforms that enable them to validate one another's thinking - even when their reasoning is nonsensical, lopsided, prejudiced, or even dangerous.
  8. Critical thinking does not yet hold an independent place in academia. Instead, "critical thinking" is continually being "defined" and redefined according to any academic area or instructor that, claiming (frequently unsupported) expertise, steps forward to teach it.

As you see, increasingly powerful trends against the teaching, learning, and practice of critical thinking entail extraordinary challenges to our mission. To continue our work, we must now rely upon your financial support. If critical thinking matters to you, please click here to contribute what you can today.

WE NEED YOUR HELP TO CONTINUE OUR WORK.

Applying A Critical Thinking Model for Engineering Education

R. J. Niewoehner
United States Naval Academy, USA

ABSTRACT:

Richard Paul's critical thinking model was adapted to the challenge of engineering education, and published in July 2006 as a guide to Engineering Reasoning. Paul's model is briefly described and exemplified by questions engineers ask in practice. This paper describes classroom exercises employing the model which are suitable for undergraduate and graduate engineering program.

INTRODUCTION:

The evaluation of our thinking as engineers requires a vocabulary of thinking and reasoning. The intellect requires a voice. Richard Paul and Linda Elder, from the Foundation for Critical Thinking, have proposed a critical thinking model documented in various sources ([1], [2] and [3]), including over a dozen Thinkers' Guides that apply this model to diverse disciplines (e.g.- [4]).

Engineers and scientists are quite comfortable working within the context of conceptual models. We employ thermodynamic models, electrical models, mathematical models, computer models or even physical models fashioned from wood or clay. Here we apply a model to the way in which we think, an architecture whose purpose is aiding the analysis and evaluation of thought, that we might improve our thought. A new thinkers' guide, Engineering Reasoning [5], applies this model to the engineering enterprise. This paper introduces this Thinkers' Guide as a tool for engineering educators and students, summarizing its content and suggesting several exercises for its use in support of engineering course and project work.

The guide follows Paul's model, providing a framework for analyzing and evaluating engineering reports, designs, graphics, and entire disciplines. It articulates the questions that exemplify maturing engineering reasoning. Several examples are provided of both excellence and disaster in engineering reasoning. The model is also applied to areas which touch engineering such as creativity, craftsmanship, and ethics.

THE PROBLEM

Elder [6] cites a series of studies indicating that college faculty almost unanimously insist that promoting critical thinking ranks among the primary goals of their work. Lamentably, that same research indicates that few college professors can articulate a substantive understanding of critical thinking, and few can identify the elements of their teaching that specifically develop critical thinking. Reference [6] appeals for the development of a substantive view of critical thinking both within higher education.

A CRITICAL THINKING MODEL

To address Elder's observation above, the analysis and evaluation of our thinking as engineers requires a vocabulary of thinking and reasoning. The model that follows is not unique to engineering; indeed, its real power is its flexibility in adapting to any domain of life and thought. Other Thinkers' Guides apply this model to other disciplines. Engineers and scientists are quite comfortable working within the context of conceptual models. We employ thermodynamic models, electrical models, mathematical models, computer models or even physical models fashioned from wood or clay. Here we apply a model of the way in which we think, an architecture whose purpose aides the analysis and evaluation of thought, that we might improve our thought.

The model depicted in Figure 1 depicts Paul's model, which the guide develops, working from the base of the diagram up.

ESSENTIAL INTELLECTUAL TRAITS

The engineer does not work in isolation, but in the context of enterprises, cultures and communities, each of which represents divergent interests and perspectives. Furthermore, no engineer can claim perfect objectivity; their work is unavoidably influenced by strengths and weaknesses, education, experiences, attitudes, beliefs, and self-interest. They avoid paths they associate with past mistakes and trudge down well worn paths that worked in the past. The profession engineer must cultivate personal and intellectual virtues.

These virtues are not radically distinct from those sought by any maturing thinker. They determine the extent to which we think with insight and integrity, regardless of the subject. The engineering enterprise does however pose distinct questions for the engineer in pursuit of such virtue.

The humble engineer asks:
  • Does my experience really qualify me to work this issue? Am I quick to admit when I'm in domains beyond my expertise?
  • To what extent do my prejudices, attitudes or experiences bias my judgment?
  • Am I open to consider novel approaches to this problem, and willing to learn and study where warranted?
The empathetic engineer asks:
  • To what extent have I analyzed the beliefs I hold which may impede my ability to think critically?
  • Do I demonstrate a willingness to yield my positions when sufficient evidence is presented against them?
  • To what extent am I willing to stand my ground against the majority (despite ridicule)?
The intellectually courageous engineer asks:
  • Do I listen and seek to understand others' reasoning?
  • Do I accurately represent viewpoints with which I disagree? Do I accurately represent their views?
  • Do I appreciate insights in the technical views of others and prejudices in my own?
Intellectual integrity asks:
  • To what extent do I expect of myself what I expect of others?
  • Do what extent are there contradictions or inconsistencies in the way I deal with technical issues?
  • To what extent do I strive to recognize and eliminate self-deception or self-interest when reasoning through engineering issues?
The persevering engineer asks:
  • Am I willing to work my way through complexities in an engineering issue or do I tend to give up when challenged?
  • Can I think of a difficult engineering problem in which I have demonstrated patience and tenacity?
Engineers with confidence in reason ask:
  • Am I willing to change my position when the evidence leads to a more reasonable position?
  • Do I adhere to technical principles and evidence when persuading others of my position or do I distort matters to support my position?
  • Do I encourage others to come to their own technical conclusions or do I try to coerce agreement?
Engineers with intellectual autonomy ask:
  • Do I think through technical issues on my own or do I merely accept others' conclusions or judgments?
  • Am I willing to stand alone against irrational criticism?
The fair-minded engineer asks:
  • Am I giving dissenting opinions adequate consideration?
  • Has self-interest or bias clouded my judgment?

FUNDAMENTAL ELEMENTS OF THINKING

All thinking entails eight elements, regardless of the domain or subject about which we're thinking. Those eight elements provide a framework for analyzing either our own thinking or the thinking of others (such as in technical reports or designs). The questions below exemplify those posed by the mature engineering thinker, grouped according to the element of thinking upon which they touch.

Purpose
  • What's the purpose of this design?
Question at hand
  • What product/process will best satisfy the customer's performance, cost and schedule requirements?
Point of View
  • A design and manufacturing point of view is typically presumed-What other Points of View deserve consideration? Stock-holders? component vendors/suppliers? marketing/sales? customers? maintenance/repair/parts? regulators? community affairs? politicians? environmentalists?
Point of View
  • What environmental or operating conditions are assumed?
  • What programmatic, financial, market, or technical risks are being accepted?
  • What market/economic/competitive environment is assumed?
  • What maturity level or maturation timeline is assumed for emerging technologies?
  • What happens if we relax or discard an assumption?
Information
  • What is the source of supporting information?
  • What information do we lack? How can we get it?
  • What experiments should be conducted?
  • Have we considered all relevant sources?
Concepts
  • What concepts are applicable to this problem?
  • Are there competing models?
  • What emerging theory might provide insight?
  • What available or emerging technologies are appropriate?
Inferences
  • What is the set of viable candidate solutions?
  • Is there another way to interpret the information?
  • Is the conclusion practicable and affordable?
Implications
  • What are the market implications of the technology?
  • Are there disposal, or environmental issues?
  • What are the implications of product failure?

APPLYING INTELLECTUAL STANDARDS

Universal intellectual standards must be applied to thinking whenever one is interested in checking the quality of reasoning about a problem, issue, or situation. The standards are not unique to engineering, but are universal to all domains of thinking. To think professionally as an engineer entails having command of these standards. While there are a number of universal standards, we focus here on some of the most significant.

Clarity
    Specific clarity questions in engineering include:
  • Are the market/mission requirements clearly stated?
  • Have terms and symbols been clearly defined?
  • Have the assumptions been clearly stated?
  • Do drawings/graphs/photos and supporting annotations clearly portray important relationships?
Accuracy
    Specific accuracy questions include:
  • What is your confidence in that data?
  • Has the test equipment been calibrated? How/when?
  • How have simulation models been validated?
  • Have assumptions been challenged for legitimacy?
Precision
    Specific precision questions include:
  • What are acceptable tolerances for diverse pieces of information?
  • Has the test equipment been calibrated? How/when?
  • What are the error bars or confidence bounds on experimental, handbook or analytical data?
Relevance
    Engineers might ask questions of relevance:
  • Have all relevant factors been weighed (e.g.- environmental, or marketplace)?
  • Are there unnecessary details obscuring the dominant factors?
  • Has irrelevant data been included?
  • Have important interrelationships been identified and studied?
  • Have features and capabilities (and hence cost) been included which the customer neither needs nor wants?
Depth
    Specific depth questions include:
  • Do models have adequate complexity and detail?
  • At what threshold does detail or additional features stop adding value?
Breadth
    For the engineer, specific breadth questions include:
  • Have the full range of options been explored?
  • Have interactions with other systems been fully considered?
  • What if the environment is other than we had expected (e.g.- hotter, colder, dusty, humid)?
Logical Validity
    For the engineer, specific logic questions include:
  • Are the design decisions supported by good analysis?
  • Are there hidden or unstated assumptions which should be challenged?
Fairness
    Appropriate fairness questions include:
  • Have other points of view been considered (stock holders, manufacturing, sales, customers, public citizens, community interests, etc.)?
  • Are vested interests inappropriately influencing the design?
  • Are divergent views given due consideration?
  • Have the environmental/safety impacts been appropriately weighed?

THE MODEL IN ENGINEERING EDUCATION

The following critical thinking exercises can employ the Engineering Reasoning Mini-Guide [5] as an in class supplement (suggested).

Fostering Intellectual Traits

Engineering students are likely puzzled at first by the suggestion that personal virtues relate to their success as engineers. The criticality of these traits becomes prominent in their interactions as members of teams. Consequently, introducing the standards and using them to foster development, is most effectively done in the context of their efforts to make their teams succeed.

As an introduction to the standards, and prior to commencing team efforts, students should read the descriptions and then discuss ensemble the value of these diverse traits. The questions they specifically want to discuss are why any of these traits will be beneficial to their team's success, and why the absence of these traits will likely hinder the team's performance.

At the conclusion of team projects, or coincident with major milestones (long duration projects), team members can be assigned to write a paragraph in which they identify a vignette in which they saw one of the intellectual traits exhibited in a way that benefited the team, and a second example identifying a vignette in which an individual or team deficit in the intellectual traits hampered team performance. The faculty member or team manager should then collate the vignettes stripping contributors' names (recognizing the team manager may be the subject of either positive or negative vignettes). A group discussion of the results should be included as part of technical debrief.

Employing the Elements of Reasoning

The real power in this taxonomy of thinking is its scalability. A topic as large as an entire course or as small as an editorial in the newspaper or a single lecture can be decomposed using the elements. The student can be asked to decompose a journal article, course topic, textbook chapter or technical report using this framework. Opportunities abound for using the eight elements both in class and outside course-work.

The eight elements can be introduced to the students in several ways. The guide includes a number of templates and examples. The most effective way for the students to become comfortable working with the elements is to review an example and then immediately apply the template to some subject area.

On the opening day of a class, the entire class can be asked to identify the eight elements associated with the prerequisite course, e.g.- "Identify the eight elements associated with the class you finished last semester in Aerodynamics. What was the purpose of Aerodynamics? What question was it trying to answer? What was the point of view? What assumptions were commonly made? What information was brought to bear? What concepts were key? What conclusions were formed? What were the implications of the material you learned?" Once students were given 6-8 minutes to do this individually, they could then share their answers either in small groups, or as a class. They could then be assigned to skim their new text's Table of Contents and decompose the new course according to the same template.

The faculty member is indispensable in keeping the elements close to the surface of the students thinking. This is best done by Socratic interaction in which the questions posed by professor apply to one of the eight elements: "What were the assumptions constraining this approach?" "What implications follow from this development?" "When we started to derive this relationship, what question are we trying to answer?" "What's the source of this insight? Was it theoretical or experimental? What empirical support do we have for this theoretical result?"

At the end of any course segment or at the end of the entire course, the students can be tasked to decompose that chapter's content or the entire course using the 8 elements. At any point during the course, the content of a relevant article can be decomposed.

The value of this practice is helping the student to provide a context for that segment or course. It provides a framework for recalling the importance of assumptions, recalling the big picture question at hand, and moving beyond the direct content to wrestling with its implications.

Teaching the Intellectual Standards

An effective means of introducing the intellectual standards is by means of reciprocal teaching. Using the Engineering Reasoning guide, students should be assigned in pairs to read the descriptions and example questions associated with Clarity and Accuracy (one student assigned to each). They should be given 3-4 minutes to prepare to explain their assigned standard to their partner, including both examples of representative questions from the guide, as well as an example they've created themselves.

In class, the standards provide a template for developing good questions to be posed in Socratic fashion. In doing so, the professor is modelling the thinking of mature engineers through the questions they pose.

Many of us struggled as new faculty trying to identify the most valuable feedback we could provide our students. On technical reports, for example, many of us wonder, "What comments can I provide a student that will best promote their learning from this experience?" The standards provide a ready vocabulary for identifying the weaknesses in student work. Moreover, if the professor's feedback consistently appeals to the standards either explicitly or implicitly, and holds students to those standards, students will be more inclined to embrace the standards as the goal they are striving to achieve.

Ancillary material

Vignettes in the back of the guide are intended to illustrate both successes and failures in engineering in our critical thinking vocabulary. They are included to foster discussion portraying the results of both excellent and deficit engineering reasoning. Students can be encouraged to research other historical examples and specifically evaluate how the success or failure of a technical enterprise turned on the quality of thought. While we commonly dissect accidents for their technical and organizational flaws, it is also illuminating to evaluate the thinking present in these episodes.

CONCLUSIONS

Our students' critical thinking implicitly undergirds all the desired skills found in any engineering syllabus. As with other engineering endeavours, models are invaluable in understanding and articulating the connections and interactions of systems and environments. This paper applied a model of critical thinking to the mind of the mature engineer, with the goal of helping us understand how to describe our own thinking and hence better develop the thinking of engineering students. It also provided a brief list of ideas for directly applying the content to the engineering classroom.

ACKNOWLEDGEMENTS

I must necessarily thank Richard Paul and Linda Elder for their decades of work as champions of critical thinking in education. It's been a delight to learn from them and collaborate in the preparation of the Engineering Reasoning guide from which this paper has been adapted.
