Engineering undergraduate lab sections are often instructed by undergraduate or graduate teaching assistants (U/GTAs), who also grade lab reports and provide feedback. Although U/GTAs contribute extensively to the assessment of lab reports, their perspectives and understanding of writing pedagogy are largely unknown. U/GTAs are primarily trained as writers in engineering; however, they are often novices in writing knowledge and its pedagogy. The electrical engineering and mechanical engineering programs of Washington State University Vancouver have conducted professional development workshops for the U/GTAs (n=6) who instruct engineering lab courses and/or grade lab reports. The goal of the workshops was to enhance the U/GTAs’ knowledge of writing and lab report evaluation to support and improve engineering undergraduate students’ lab report writing. The workshop contents consisted of 1) lab instructors’ expectations, 2) the fundamentals of lab report writing (rhetorical features of lab reports), and 3) productive feedbacks. The workshops were offered to six U/GTAs from five courses (two sophomore, two junior, and one senior electrical engineering lab courses). In order to identify the overall effectiveness of the workshops, we conducted the survey and focus group with the U/GTAs to investigate their writing background, their understanding of audience awareness, their perspectives and understanding of writing instruction, and their lab report evaluation processes. We also collected the graded lab reports to investigate feedback comments. This paper discusses the U/GTAs’ perspectives and their practices of writing pedagogies in the lab courses. The knowledge generated from this study has provided a direction for refining the professional development workshops for U/GTAs in the present and future.

                            A Pilot Study Inquiring into the Impact of ChatGPT on Lab Report Writing in Introductory Engineering Labs
                        
                    
    
            This exploratory study focuses on the use of ChatGPT, a generative artificial intelligence (GAI) tool, by undergraduate engineering students in lab report writing in the major. Literature addressing the impact of ChatGPT and AI on student writing suggests that such technologies can both support and limit students' composing and learning processes. Acknowledging the history of writing with technologies and writing as technology, the development of GAI warrants attention to pedagogical and ethical implications in writing-intensive engineering classes. This pilot study investigates how the use of ChatGPT impacts students’ lab writing outcomes in terms of rhetorical knowledge, critical thinking and composing, knowledge of conventions, and writing processes. A group of undergraduate volunteers (n= 7) used ChatGPT to revise their original engineering lab reports written without using ChatGPT. A comparative study was conducted between original lab report samples and revisions by directly assessing students’ lab reports in gateway engineering lab courses. A focus group was conducted to learn their experiences and perspectives on ChatGPT in the context of engineering lab report writing. Implementing ChatGPT in the revision writing process could result in improving engineering students’ lab report quality due to students’ enhanced lab report genre understanding. At the same time, the use of ChatGPT also leads students to provide false claims, incorrect lab procedures, or extremely broad statements, which are not valued in the engineering lab report genre.

            Engineering undergraduates’ academic writing experiences prior to entry-level engineering lab courses can be classified into three different groups: a group with both rhetorically-focused writing (e.g., first-year-composition) and technical writing courses; a group with only rhetorically-focused writing courses; and a group with no rhetorically-focused writing or technical writing courses. Using a lens of transfer theories that explain how much knowledge from one context is used or adapted in new contexts, these three groups can be called concurrent, vertical, and absent transfer groups respectively. This study, which is part of a larger project developing and implementing writing-focused modules in engineering labs, aims to investigate undergraduates’ perspectives on readiness, writing transfer, and effectiveness of writing instructions in engineering lab report writing through a student survey. End-of-term online surveys (n = 40) of undergraduates in entry-level engineering lab courses were collected from three distinctive universities: an urban, commuter, public research university; an urban, private, teaching-focused university; and a rural, public, teaching-focused university. The survey questions have three parts: 1) student perspectives in writing in engineering disciplines; 2) how students use prior writing knowledge when writing lab reports in engineering lab courses; and 3) how engineering lab course writing instructions impact students’ engineering lab report writing. Findings suggest that the three transfer groups present statistical distinctions on the readiness of writing engineering lab reports (concurrent group as the highest and absent group as the lowest). The three groups also show different perspectives on how their freshmen writing courses contributed their engineering lab report writing. The concurrent transfer group believed freshmen writing instruction regarding “focus on purpose” contributed most when they write lab reports, while the greatest number of vertical transfer group students mentioned “knowledge about format and structure” was most helpful. Many absent transfer students valued “identifying problems or questions” instructed from their freshmen writing-intensive philosophy course as the content they used most when writing lab reports. Ultimately, the analysis of the data suggested that despite their perceived preparedness for writing lab reports, most of the students felt their skills improved as a result of engaging in lab report writing activities.more » « less
