Title: Augmenting the classical change model to promote conceptual learning in core engineering courses
Cognitive conflict arises when students’ expectation about a physical situation, such as the relative temperatures of metal and cloth, are not experimentally verified. The paper reviews this approach as a tool for promoting conceptual learning in undergraduate engineering courses, through three case studies. These cases demonstrate that cognitive conflict can be a successful strategy for engineering instructors to support students’ conceptual learning in engineering as a first step to create a teachable moment.  more » « less

  1. Practice plays a critical role in learning engineering dynamics. Typical practice in a dynamics course involves solving textbook problems. These problems can impose great cognitive load on underprepared students because they have not mastered constituent knowledge and skills required for solving whole problems. For these students, learning can be improved by being engaged in deliberate practice. Deliberate practice refers to a type of practice aimed at improving specific constituent knowledge or skills. Compared to solving whole problems requiring the simultaneous use of multiple constituent skills, deliberate practice is usually focused on one component skill at a time, which results in less cognitive load and more specificity. Contemporary theories of expertise development have highlighted the influence of deliberate practice (DP) on achieving exceptional performance in sports, music, and various professional fields. Concurrently, there is an emerging method for improving learning efficiency of novices by combining deliberate practice with cognitive load theory (CLT), a cognitive-architecture-based theory for instructional design. Mechanics is a foundation for most branches of engineering. It serves to develop problem-solving skills and consolidate understanding of other subjects, such as applied mathematics and physics. Mechanics has been a challenging subject. Students need to understand governing principles to gain conceptual knowledge and acquire procedural knowledge to apply these principles to solve problems. Due to the difficulty in developing conceptual and procedural knowledge, mechanics courses are among those that receive high DFW rates (percentage of students receiving a grade of D or F or Withdrawing from a course), and students are more likely to leave engineering after taking mechanics courses. Deliberate practice can help novices develop good representations of the knowledge needed to produce superior problem solving performance. The goal of the present study is to develop deliberate practice techniques to improve learning effectiveness and to reduce cognitive load. Our pilot study results revealed that the student mental effort scores were negatively correlated with their knowledge test scores with r = -.29 (p < .05) after using deliberate practice strategies. This supports the claim that deliberate practice can improve student learning while reducing cognitive load. In addition, the higher the students’ knowledge test scores, the lower their mental effort was when taking the tests. In other words, the students who used deliberate practice strategies had better learning results with less cognitive load. To design deliberate practice, we often need to analyze students’ persistent problems caused by faulty mental models, also referred to as an intuitive mental model, and misconceptions. In this study, we continue to conduct an in-depth diagnostic process to identify students’ common mistakes and associated intuitive mental models. We then use the results to develop deliberate practice problems aimed at changing students’ cognitive strategies and mental models.

  3. This paper details the process of developing and adapting a narrative framework for teaching an introductory geotechnical engineering course (EGR 340) through a systematic iterative procedure that embeds conceptual learning into a story format and, over time, elaborates elements and interactions within the story using methods of transmedia storytelling. Although the tools are presented within the context of geotechnical engineering, the approach can be applied throughout engineering education. The elaborative transmedia storytelling process we describe is based on the Imaginative Education (IE) teaching approach. Well-grounded in the learning sciences--but novel in engineering education--IE facilitates student engagement through the use of cognitive tools (such as extremes of reality, heroism, and the exploration of binaries). These tools are connected to types of understanding and serve to enhance a sense of mystery and wonder for topics that might not otherwise register as being immediately relevant to students. A significant benefit of this approach is that that it lends itself to modification and personalization through the inclusion of new features and methods of interaction at the level of the whole story and at the level of story elements. Four types of understanding and their associated cognitive tools were used in EGR 340 and their application is described in this paper. They include: • Mythic understanding using a fantasy narrative that played on the idea that geotechnical engineers refer to their field as the “dark arts of engineering.” • Romantic understanding using heroic narratives that helped students put themselves in the place of Terzaghi and Casagrande as they developed the field. Extremes of reality was another Romantic tool used throughout the course. For example, students learned about soil stress by first solving the mystery of how quicksand works. • Theoretic understanding using concept maps and narrative was used at both the course and unit level to organize concepts. • Ironic understanding using discussion of the inadequacies of theoretic understanding to recognize the reference to “dark arts.” Transmedia storytelling through extensive use of short video clips and other means was used to enhance the application of these tools. For example, students traveled virtually to Venice where they joined a noisy gondola tour to examine building foundations and learn about how poor water policies impacted the sinking of the city. Course evaluation and lesson assessment data were collected in 2018, 2020, and 2022, with each year being associated with a different version of the course. Using these data, we present a mixed-methods analysis of learning outcomes that provides evidence for the effectiveness of this approach at different steps along the way. Non-parametric comparisons of student assessment data demonstrated that student conceptual learning was relatively stable across measures and versions, but that students in the fully transmedia iteration generally performed more strongly on assessments of project-based learning (Borrow/Fill; Atterberg; Dam). Thematic analysis of student responses to open-ended course evaluation prompts demonstrates that engagement was high across all versions of the course, and that students in the 2022 version discussed engineering topics in a manner that included personal connections and reflections.

  4. Learning is usually conceptualized as a process during which new information is processed in working memory to form knowledge structures called schemas, which are stored in long-term memory. Practice plays a critical role in developing schemas through learning-by-doing. Contemporary expertise development theories have highlighted the influence of deliberate practice (DP) on achieving exceptional performance in sports, music, and different professional fields. Concurrently, there is an emerging method for improving learning efficiency by combining deliberate practice with cognitive load theory (CLT), a cognition-architecture-based theory for instructional design. Mechanics is a foundation for most branches of engineering. It serves to develop problem-solving skills and consolidate understanding of other subjects, such as applied mathematics and physics. Mechanics has been a challenging subject. Students need to understand governing principles to gain conceptual knowledge and acquire procedural knowledge to apply these principles to solve problems. Due to the difficulty in developing conceptual and procedural knowledge, mechanics courses are among those which receive high DFW rates (percentage of students receiving a grade of D or F or Withdrawing from a course) and students are more likely to leave engineering after taking mechanics courses. Since deliberate practice can help novices develop good representations of the knowledge needed to produce superior problem solving performance, this study is to evaluate how deliberate practice helps students learn mechanics during the process of schema acquisition and consolidation. Considering cognitive capacity limitations, we will apply cognitive load theory to develop deliberate practice to help students build declarative and procedural knowledge without exceeding their working memory limitations. We will evaluate the effects of three practice strategies based on CLT on schema acquisition and consolidation in two mechanics courses (i.e., Statics and Dynamics). Examples and assessment results will be provided to evaluate the effectiveness of the practice strategies as well as the challenges.
