1. An Exploration of Concept Mapping as a Reflective Approach for Instructors When Evaluating Problem Design Intent

   Olewnik, A.; Ferguson, S.; Sheikh, N.; Mariappan, A.; Schrewe, L. (January 2022, Proceedings ASEE Annual Conference and Exposition)

   Introduction: The work reported here subscribes to the idea that the best way to learn - and thus, improve student educational outcomes - is through solving problems, yet recognizes that engineering students are generally provided insufficient opportunities to engage problems as they will be engaged in practice. Attempts to incorporate more open-ended, ill-structured experiences have increased but are challenging for faculty to implement because there are no systematic methods or approaches that support the educator in designing these learning experiences. Instead, faculty often start from the anchor of domain-specific concepts, an anchoring that is further reinforced by available textbook problems that are rarely open in nature. Open-ended problems are then created in ad-hoc ways, and in doing so, the problem-solving experience is often not realized as the instructor intended. Approach: The focus in this work is the development and preliminary implementation of a reflective approach to support instructors in examining the design intent of problem experiences. The reflective method combines concept mapping as developed by Joseph Novak with the work of David Jonassen and his characterization of problems and the forms of knowledge required to solve them. Results: We report on the development of a standard approach – a template -- for concept mapping of problems. As a demonstration, we applied the approach to a relatively simple, well-structured problem used in an introductory aerospace engineering course. Educator-created concept maps provided a visual medium for examining the connectivity of problem elements and forms of knowledge. Educator reflection after looking at and discussing the concept map revealed ways in which the problem engagement may differ from the perceived design intent. Implications: We consider the potential for the proposed method to support design and facilitation activities in problem-based learning (PBL) environments. We explore broader implications of the approach as it relates to 1) facilitating a priori faculty insights regarding student navigation of problem solving, 2) instructor reflection on problem design and facilitation, and 3) supporting problem design and facilitation. Additionally, we highlight important issues to be further investigated toward quantifying the value and limitations of the proposed approach.

2. Concept Maps Lead to Better Problem Statements: An Empirical Study Measuring the Effects of Priming Students to Think in Systems

   https://doi.org/10.1061/9780784483985.024

   Challenges associated with the design and construction of the built environment are complex. Students need training to help them deal with this complexity and to help them explore and reframe problems early during project planning and design. Concept maps provide a visual representation of complex information and the relationships between this information. The research presented in this paper tested whether priming students to think in systems by asking them to draw concept maps changes how they construct problem statements. In total, 40 engineering students participated in the study. Half were asked to draw a concept map before constructing a problem statement about how to improve mobility systems around campus. The cognitive effort (i.e., time and words) students spent on the task and the number of unique system elements included in their problem statement were measured. Students that received the concept mapping intervention spent significantly more time thinking about the problem, developed longer problem statements, and included more unique elements of systems. These findings suggest using concept mapping can aid students’ conceptualization of complex problems.

3. How the use of concept maps changes students’ minds and brains.

   Shealy, T.; Gero, J.; Ignacio Jr, P. (July 2022, ASEE Annual Conference & Exposition)

   The research presented in this paper tested whether drawing concept maps changes how engineering students construct design problem statements and whether these differences are observable in their brains. The process of identifying and constructing problem statements is a critical step in engineering design. Concept mapping has the potential to expand the problem space that students explore through the attention given to the relationship between concepts. It helps integrate existing knowledge in new ways. Engineering students (n=66) were asked to construct a problem statement to improve mobility on campus. Half of these students were randomly chosen to first receive instructions about how to develop a concept map and were asked to draw a concept map about mobility systems on campus. The semantic similarity of concepts in the students’ problem statements, the length of their problem statements, and their neurocognition when developing their statements were measured. The results indicated that students who were asked to first draw concept maps produced a more diverse problem statement with less semantically similar words. The students who first developed concept maps also produce significantly longer problem statements. Concept mapping changed students’ neurocognition. The students who used concept mapping elicited less cognitive activation in their left prefrontal cortex (PFC) and more concentrated activation in their right PFC. The right PFC is generally associated with divergent thinking and the left PFC is generally associated with convergent and analytical thinking. These results provide new insight into how educational interventions, like concept mapping, can change students’ cognition and neurocognition. Better understanding how concept maps, and other tools, help students approach complex problems and the associated changes that occur in their brain can lay the groundwork for novel advances in engineering education that support new tools and pedagogy development for design.

4. Board 197: A Gamified Approach for Active Exploration to Discover Systematic Solutions for Fundamental Engineering Problems

   Ilbeigi, Mohammad; Bairaktarova, Diana; Ehsani, Romina (June 2023, 2023 ASEE Annual Conference & Exposition)

   Previous studies have convincingly shown that traditional, content-centered, and didactic teaching methods are not effective for developing a deep understanding and knowledge transfer. Nor does it adequately address the development of critical problem-solving skills. Active and collaborative instruction, coupled with effective means to encourage student engagement, invariably leads to better student learning outcomes irrespective of academic discipline. Despite these findings, the existing construction engineering programs, for the most part, consist of a series of fragmented courses that mainly focus on procedural skills rather than on the fundamental and conceptual knowledge that helps students become innovative problem-solvers. In addition, these courses are heavily dependent on traditional lecture-based teaching methods focused on well-structured and closed-ended problems that prepare students to plug variables into equations to get the answer. Existing programs rarely offer a systematic approach to allow students to develop a deep understanding of the engineering core concepts and discover systematic solutions for fundamental problems. Without properly understanding these core concepts, contextualized in domain-specific settings, students are not able to develop a holistic view that will help them to recognize the big picture and think outside the box to come up with creative solutions for arising problems. The long history of empirical learning in the field of construction engineering shows the significant potential of cognitive development through direct experience and reflection on what works in particular situations. Of course, the complex nature of the construction industry in the twenty-first century cannot afford an education through trial and error in the real environment. However, recent advances in computer science can help educators develop virtual environments and gamification platforms that allow students to explore various scenarios and learn from their experiences. This study aims to address this need by assessing the effectiveness of guided active exploration in a digital game environment on students’ ability to discover systematic solutions for fundamental problems in construction engineering. To address this objective, through a research project funded by the NSF Division of Engineering Education and Centers (EEC), we designed and developed a scenario-based interactive digital game, called Zebel, to guide students solve fundamental problems in construction scheduling. The proposed gamified pedagogical approach was designed based on the Constructivism learning theory and a framework that consists of six essential elements: (1) modeling; (2) reflection; (3) strategy formation; (4) scaffolded exploration; (5) debriefing; and (6) articulation. We also designed a series of pre- and post-assessment instruments for empirical data collection to assess the effectiveness of the proposed approach. The proposed gamified method was implemented in a graduate-level construction planning and scheduling course. The outcomes indicated that students with no prior knowledge of construction scheduling methods were able to discover systematic solutions for fundamental scheduling problems through their experience with the proposed gamified learning method.

5. Physical Physics – Getting students Active in Learning Materials Science

   https://doi.org/10.1557/adv.2017.61

   ABSTRACT Physics forms the core of any Materials Science Programme at undergraduate level. Knowing the properties of materials is fundamental to developing and designing new materials and new applications for known materials. “Physical Physics” is a physics education approach which is an innovative and promising instruction model that integrates physical activity with mechanics and material properties. It aims to significantly enhance the learning experience and to illustrate how physics works, while allowing students to be active participants and take ownership of the learning process. It has been successfully piloted with undergraduate students studying mechanics on a Games Development Programme. It is a structured guided learning approach which provides a scaffold for learners to develop their problem solving skills. The objective of having applied physics on a programme is to introduce students to the mathematical world. Today students view the world through smart devices. By incorporating student recorded videos into the laboratory experience the student can visualise the mathematical world. Sitting in a classroom learning about material properties does not easily facilitate an understanding of mathematical equations as mapping to a physical reality. In order to get the students motivated and immersed in the real mathematical and physical world, an approach which makes them think about the cause and effect of actions is used. Incorporating physical action with physics enables students to assimilate knowledge and adopt an action problem solving approach to the physics concept. This is an integrated approach that requires synthesis of information from various sources in order to accomplish the task. As a transferable skill, this will ensure that the material scientists will be visionary in their approach to real life problems.
