Abstract

The need to improve problem solving skills in STEM undergraduates has been widely reported1. This Works in Progress paper seeks to provide additional insight into the role of knowledge structure, knowledge retention, and misconceptions in solving open-ended biomedical engineering design problems. Correlations in problem solving performance to level of metacognitive awareness will also be assessed. As part of a larger multidisciplinary study, we seek to develop a model describing undergraduates’ STEM problem solving performance to serve as a tool to guide support of students’ problem solving skill development.

Current study participants are enrolled in a first year introductory biomedical engineering (BME) course aimed to introduce the field through BME specialization introductory lectures, prospective BME career guest lectures, and team-based hands-on design challenges. This two unit course consists of one 50 minute lecture and a 3 hour discussion session focused on engineering design each week. The majority of the 142 enrolled students are first quarter freshman engineering students, of which all BME students are required to take.

To gather a baseline of students’ design knowledge, the Comprehensive Assessment of Design Engineering Knowledge (CADEK) diagnostic test2 was administered to all students in the first week of class and will be administered during the last week of class. Upon consent, students were also asked to complete an online Metacognitive Awareness Inventory (MAI)3 during week 2. In addition to the CADEK and MAI, students will also answer an open ended design problem on their first quiz (in Week 5), in which ten high performing and ten low performing students will be identified and asked to participate in one hour think aloud interviews (TAInt). TAInt will be conducted in such a way to encourage participants to speak through their thought processes while asked to solve several open ended BME design problems. Following the TAInt, which will be held during week 7 and 8 of the quarter, participants will be asked to complete a follow up CADEK and participate in a second round of TAInt during the next quarter utilizing the same open ended problems. Level of knowledge retention will be assessed.

Several developed instruments will be utilized to analyze the open ended design problems from quiz 1 and transcribed TAInt. The COSINE (Coding System for Investigating Sub-problems and the Network) method in particular, is an in-depth analysis of the difficulties students have during the problem solving process4. In order to utilize the COSINE method, sub-problems, which will correlate to the specific steps of the engineering design process, will be assigned a code based on student performance in a particular task. Quantitative metrics will be developed based on resulting codes to gain insight into where and why students are unsuccessful. MAI and CADEK results will also be assessed and correlated to quantitative metrics generated. Assessing study participants over the course of the BME undergraduate curriculum will also provide insight into strengths and areas for improvement of design instruction across the curriculum.
