Dr. Sonia Bansal is an Assistant Professor of the Practice for the Department of Biomedical Engineering at Duke University. She has been teaching for the department for 2 years and is researching best practices of curricular integration of technical skills such as writing, computing, and design. She graduated from the University of Pennsylvania with a Ph.D. in Bioengineering in 2020 from the McKay Orthopedic Research Laboratory under the guidance of Dr. Robert Mauck and uses her background in orthopedic engineering to develop courses in the biomechanics and biomaterials space. Dr. Bansal teaches 4 classes a year including BME 221: Biomaterials, EGR 201: Mechanics of Solids, BME 530: Introduction to Tissue Biomechanics, and EGR 101: Engineering Design and Communication. She is the co-director of the Biomedical Engineering Education & Teaching Laboratory (BEETL) at Duke.
Kat Lazar is a PhD Candidate in Biomedical Engineering at Duke University. She works in the labs of Joel Collier and Ashutosh Chilkoti to develop protein-based biomaterials to address diseases of the immune system. She obtained her bachelor's in chemical and biological engineering from Tufts University, where she also received a minor in education. Kat has over five years of experience as a teaching assistant in a variety of lecture- and lab-based science courses, including general chemistry, undergraduate level biomaterials, and graduate level biomolecular engineering. She is an NSF GRFP recipient and a fellow at the Duke University Center for Biomolecular and Tissue Engineering, an interdisciplinary consortium that trains students in scientific communication and collaborative skills.
Jaron Shoemaker is an incoming Ph.D. student in the Biomedical Engineering Department at Rensselaer Polytechnic Institute. He will be working under the mentorship of Dr. David Corr on innovative cancer model fabrication and tissue engineering research. He graduated with a B.S.E. in Biomedical Engineering from Duke University in 2025.
Dr. Elizabeth Feeney is a Senior Lab Administrator in the Biomedical Engineering Teaching Laboratories at Duke University. She coordinates, develops, and teaches labs in biomaterials, mechanics, and physiology. She graduated with a PhD in biomedical engineering from Cornell University in 2020.
Introduction and Motivation Technical communication focuses on conveying scientific information in a clear and concise way. In preparing engineering students for the workforce, many upper-level engineering courses require students to complete technical writing assignments like lab reports, scientific posters, and oral presentations(1). These approaches not only test recall, understanding, and application of course material, but also help students analyze and evaluate data and/or primary literature(2). While important experiences, communication-based assignments are challenging for students. They are evaluated qualitatively and often use task-focused rubrics, which are essential for efficient and multi-grader agreement(3). However, this leads to students focusing on producing work that fits specifications instead of on skill development. To help students develop writing as a skill, our course has implemented “scaffolding” for students as they write lab reports.
Scaffolding was first introduced by Wood and colleagues in 1976(4) to describe creating support within an assignment to enhance student performance. In general, it is meant to decrease cognitive load for learners and additionally help students accomplish tasks in the present while improving performance in the future(5). Broadly, scaffolding has been used across disciplines and student level, and it is for this reason that we believe it can be applied to technical writing. A core strategy in scaffolding is to reduce assistance over time, allowing students to progressively grow skills and build independent mastery(6,7). “Scaffold fading”, as implemented by Chang and colleagues(7), supports this framework by reducing the amount of support given to students in subsequent assignments. In this study, scaffold fading was found to be an improvement over the control group(7).
Here, we describe a “diminishing scaffold” in conjunction with high-feedback grading on lab reports. Our goal is to interrogate if providing high feedback and diminishing scaffolds for lab reports leads to higher quality lab reports at the end of the semester, and if students’ perceptions of their writing skill is improved by this support.
Methods This study takes place in a required biomaterials course with four laboratory experiences. Students work in teams to complete experiments and then complete independent lab reports in which they analyze data and use their findings to provide recommendations on biomedical device design.
Two aspects are scaffolded – first, the protocol is set up as a worksheet with guiding questions, prompts, and space to sketch/brainstorm figures. It is set up to inform their data analysis, discussion, and figure generation in the report. Worksheets are graded for effort and the teaching team leaves detailed feedback to help students as they write their lab reports. The number of questions and associated points on the worksheet decreases from the first lab (many required questions, thirty points) to the last lab (few optional questions, zero points).
The complementary scaffold is for the lab report. These are suggested/optional outlines for the written report. The scaffold for the first lab is detailed and suggests specific, key, topics to expound on in the introduction and discussion sections. It also features suggested figure captions and styles and example phrasing for objectives and procedure sections. The scaffold becomes more general in the second lab, focusing on themes to cover instead of exact topics to discuss. In the third lab, the scaffold is even more generalized, with some sections (procedure, objectives, conclusion) blank, and other sections suggesting that students write about material-nonspecific concepts. The last lab’s scaffold is blank. The teaching team provides detailed feedback and returns reports quickly to ensure continuous improvement. As scaffold support decreases, the points associated with the report increase (first: 20 points, last: 50 points), such that the total score for each lab is out of 50 points.
After submitting the lab report, students complete a self-reflection including two likert-style and four free-response questions. Likert-type questions include “I was able to follow the protocol for this lab” and “I feel confident that I can write a lab report”. Free-response questions ask students to share the “muddiest point and their most/least favorite aspects of the lab.
This work was approved by [INSTITUTION] IRB under protocol #2024-0218. Primary outcomes will include scores on each report, responses to the Likert-type questions, and coding of free-response questions. Secondary outcome measures include trends in lab report scores across reports to determine the impact of continuous feedback and reflection and trends in student confidence over time.
Future Plans Spring 2024 data has been collected and analysis is in progress. Fall 2024 data is currently being collected. Through this study, we hope to develop best practices in teaching technical writing for long-term skill development.
