The Accreditation Board for Engineering & Technology (ABET) requires that engineering students graduate with “an ability to communicate effectively”1, hence the need for problem based learning approaches that also foster scientific writing skills. This need is typically met through student hands-on experiences and follow-up laboratory reports. Research indicates science concept understanding improves with the use of unstructured context maps and that writing-to-learn practices can greatly improve student learning and engagement but are lacking in STEM 2,3,4. To address these findings we developed a fading paradigm scaffolding approach to maximize engineering students’ communications skills. Our goal is to increase the writing capability of undergraduates to a level of graduate students by utilizing a fading paradigm scaffolding approach where writing templates become less structured over time. We hypothesize that this approach will increase writing ability over the course of one semester for all undergraduates and by the end of one semester, undergraduates will write at a level comparable to entry-level graduate students.
Bioengineering Mechanics I is a junior level course for biomedical engineers (BME), whereas Orthopaedic Biomechanics is a cross-listed course for both senior level mechanical engineers (ME) and graduate students from a variety of backgrounds including biomechanics, BME, and ME. Both courses take place over a 14-week semester (Fall 2012-2015). In both courses students complete four lab exercises. Each lab explores different concepts in statics, mechanics of materials, and orthopaedic biomechanics. Depending on level of study, undergraduate versus graduate, the lab write-up portion varied. For all labs, graduate students received an abstract formatting template with only subheadings. For the first two labs, undergraduate students received a template with a completed Introduction and Methods section requiring students to write the results and conclusion sections in the context of the provided introduction and methods. For the last two labs, undergraduate students received the same templates as the graduate students, forcing students to develop all sections of the abstract.
Writing samples for all labs and all students will be used for evaluation. To evaluate writing skills, 4 instructors will complete writing assessments of completed abstracts, blinded to both group and time point. Writing samples will be assessed using a rubric based on a compilation of grading schemes used by different professional societies (BMES, CSM, GCMAS). Writing scores from each time point for both groups will evaluate writing quality changes over time. Because the scaffolding changes throughout the semester this assessment will only include the results and conclusion sections. We will additionally compare final lab write up scores (Lab #4) from undergraduates to initial lab write up scores (Lab #1) of graduate students to determine if our approach results in entry level graduate student writing quality for the undergraduates. This assessment will include all sections of the abstract (Introduction, Methods, Results, & Conclusion). These assessments will be used to identify potential writing mechanisms that can be used to develop strong writing skills.
