Research

research overview

  • Aaron Johnson's research focuses on how mathematical models are taught in undergraduate engineering science courses and how these models are used in analysis and design. Homework and exams often ask students to apply mathematical models to well-defined problems for which there is a single correct answer. However, professional engineers deal with ill-defined, complex problems in which the core engineering practice is not the calculation of the answer but the modeling of the problem. The modeling abilities of engineers are the quality of engineering judgment, and Johnson's research seeks to understand how undergraduate engineering students can engage in the productive beginnings of engineering judgment. He also develops assignments and technology tools to engage students in these productive beginnings.

  • ASEN 3112 - Structures
    Primary Instructor - Spring 2020
    Teaches Mechanics of Materials methods of stress and deformation analysis applicable to the design and verification of aircraft and space structures. It offers an introduction to matrix and finite element methods for truss structures, and to mechanical vibrations.
  • ASEN 4018 - Senior Projects 1: Design Synthesis
    Primary Instructor - Fall 2019
    Focuses on the synthesis of technical knowledge, project management, design process, leadership, and communications within a team environment. Students progress through the design process beginning with requirements development, then preliminary design and culminating with critical design. Offered fall only.
  • ASEN 4028 - Senior Projects 2: Design Practicum
    Primary Instructor - Spring 2020
    Focuses on the fabrication, integration, verification and validation of designs produced in ASEN 4018. Students work within the same teams from ASEN 4018. Offered spring only.
