Short answer

Designers should consciously cultivate a broader range of mental representations and actively engage in metacognitive processes like planning, monitoring, and evaluation to enhance their problem-solving effectiveness.

Field: User-Centred Design
Source: Illinois Digital Environment for Access to Learning and Scholarship (University of Illinois at Urbana-Champaign) (2010)
Method: Qualitative analysis of verbal protocols
Sample: 10 participants (6 students, 4 professionals)
Evidence: Moderate effect

Professional engineers demonstrate more sophisticated use of mental representations and metacognitive strategies compared to students when tackling design challenges. This user-centred design research insight is drawn from a 2010 study published in Illinois Digital Environment for Access to Learning and Scholarship (University of Illinois at Urbana-Champaign). Using Qualitative analysis of verbal protocols with 10 participants (6 students, 4 professionals), researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers should consciously cultivate a broader range of mental representations and actively engage in metacognitive processes like planning, monitoring, and evaluation to enhance their problem-solving effectiveness.

Key Findings

01Differences exist in the frequency, types, and attributes of mental representations used by students and professionals.
02Metacognitive regulation strategies (planning, monitoring, evaluation) differ in frequency and characteristics between the two groups.
03The interplay between mental representation and metacognitive regulation is linked to distinct engineering design strategies.

Application

Design takeaway

How to apply

Incorporate structured reflection and self-assessment techniques into the design process to mimic the metacognitive strategies of experts.

Project actions

01When documenting your design process, explicitly describe the mental models (like analogies or metaphors) you used.
02Include sections in your design report that detail how you planned, monitored, and evaluated your design decisions.

Method & Evidence

AimTo investigate the differences in mental representation and metacognitive regulation between student and professional engineers during an engineering design problem-solving task.

MethodQualitative analysis of verbal protocols

ProcedureParticipants (mechanical engineering students and professional mechanical engineers) solved an engineering design problem. Concurrent and retrospective verbal protocols were collected, audio-recorded, transcribed, and coded to analyze the frequency, types, and attributes of mental representations (propositions, metaphors, analogies) and metacognitive regulation (planning, monitoring, evaluation).

Sample10 participants (6 students, 4 professionals)

ContextEngineering design problem-solving

Variables

IVExpertise level (student vs. professional engineer)

DVFrequency, types, and attributes of mental representations; frequency and characteristics of metacognitive regulation; overall design strategy.

CVEngineering discipline (mechanical engineering), type of design problem.

Strengths & Limitations

Strengths

+Direct observation of cognitive processes through verbal protocols.
+Comparison between distinct groups (students and professionals).

Limitations

It can be challenging to accurately capture and code complex cognitive processes from verbal protocols alone.

Reliability & validity

The reliability of coding verbal protocols can be improved through inter-rater reliability checks. Validity is supported by the direct observation of cognitive processes, though the artificiality of the task might affect ecological validity.

Think critically

To what extent can metacognitive strategies be taught and learned, and how might this impact the development of novice designers?

Design Principles

"Effective design problem-solving is enhanced by the deliberate use of diverse mental representations and robust metacognitive regulation."

Understanding the cognitive processes that differentiate expert and novice designers is crucial for developing effective training programs and design tools. This insight can inform how we structure design education and support systems to foster higher levels of design proficiency.

What This Means for Your Design

Experienced engineers think about problems in more complex ways and are better at checking their own work than students.
