Concept Mapping as a Metacognition Tool in a Problem-Solving-Based BME Course During In-Person and Online Instruction.

ABSTRACT: Metacognitive skills can have enormous benefits for students within engineering courses. Unfortunately, these metacognitive skills tend to fall outside the content area of most courses, and consequently, they can often be neglected in instruction. In this context, previous research on concept mapping as a teaching strategy points to meaningful learning. The purpose of this innovation paper is to report an application of concept mapping (1) to facilitate metacognition steps in students, and (2) to identify the muddiest points students struggle with, during both in-person and online instruction of a problem-solving-based biomedical engineering course. This innovation article also looks at the usefulness of concept mapping through instructor and student perceptions and students' class performance. The entire concept mapping intervention was conducted during weeks 8-10 of the Spring 2019 in-person quarter and during weeks 3-4 and 8-10 of the Spring 2021 online quarter. The exercise involved concept mapping, explanation and discussion with peers, and answering structured reflection prompts. Each concept map activity was contextualized to the metacognitive knowledge domain of the revised Bloom's taxonomy. The average class performance was compared between students who completed concept mapping vs. those who did not, using a t-test and one-way ANOVA at alpha = 0.05 significance level followed by a Tukey HSD test. Students' concept maps and reported answers were analyzed qualitatively following the concept mapping intervention. During the Spring 2019 in-person quarter, 59.30% of students completed concept mapping with reflection, whereas 47.67% completed it in spring 2021 online instruction. A two-tailed, unpaired t-test indicated that concept mapping did not significantly enhance students' class performance (p > 0.05) within each of the in-person and online instructions. Peers' suggestions to students to improve concept maps revealed themes related to course concepts, prerequisite concepts, and the act of concept mapping itself. Concept mapping was effective in revealing the muddiest points of the course. Concept mapping did not significantly enhance students' class performance either in-person or online instruction (effect sizes were 0.29 for the 2019 in-person quarter and 0.33 for the 2021 online quarter). However, instructors and students' perceptions reflected that concept mapping facilitated metacognition in a problem-solving-based biomedical engineering course both during in-person and online instruction. Most students (78%) were optimistic about the usefulness of concept mapping for this course, and 84% were inclined to apply it for a variety of other courses.

Project description:With a motivation to immerse students in engineering design, graphics communication, and computer aided design (CAD) skills early-on in the biomedical engineering curriculum, we launched a new 2-unit laboratory course on "Graphics Design in BME" in the Spring 2020 quarter for UC Davis sophomores. Due to the COVID-19 pandemic, the course met with the significant challenge of conversion to an online mode of teaching, instead of planned face-to-face instruction. Providing formative feedback was thought to be an important step to help students succeed in their final CAD project of the course. In the process of designing feedback, we found that the concept of feedback is still fragile in an online learning environment because online learning settings provide distinct pedagogical demands as compared to face-to-face settings. The situation is especially delicate in the context of contemporary higher education imparting engineering skills, where students attend large classes, with diminished opportunities to interact with the teaching staff. The challenge we faced was to provide meaningful dialogic feedback in an online environment, especially while teaching engineering graphics design to a large class. Here we addressed this challenge by focusing on the process of structuring meaningful feedback. We designed a project assignment to be submitted as multiple deliverables to be submitted in two-stages. Then, we characterized its feedback with multiple notions, such as dialogic iterative cycles, personalized, goal-directed, immediate, in written format, and having a peer assessment component. The process of providing formative feedback online through the structure mentioned in this paper resulted in students' improved scores on the final project elements. It also helped us identify the common issues students are faltering in a graphics design class, and provide customized guidance, ideal examples of expected work, and more resources to motivate each student group to achieve mastery of course content.Supplementary informationThe online version contains supplementary material available at 10.1007/s43683-021-00046-z.
