The chair commented on the abstract:

The reviewer has shared critical feedback with you, and as Program Chair fro DELOS, I am willing to discuss their comments with you as you prepare your paper. - Dr. Sally Pardue, spardue@tntech.edu

The chair commented on the draft:

Please submit a revised paper incorporating the review comments. If you have questions or concerns, please contact me. -Sally Pardue, DELOS Program Chair, 2020. spardue@tntech.edu

A reviewer commented on the draft
There are several typographical errors in the submission which should be corrected. One example - on pg. 2, paragraph 1, sentence 3 there is '??' instead of a citation number. The document must be proofread more thoroughly and resubmitted.

It would seem that there is a possibility of a repeated measures analysis on the laboratory report scores themselves. Why was this not done?

Also, presumably, students are scored on their senior design work. Yet, only student opinion about their own level of preparedness was analyzed. Why not measure and analyze the actual work and not just student opinion?

Although not specifically identified, it would seem that this involves human subject research (surveys from students analyzed and the results being published) which might fall under an Institutional Review Board. I did not notice that IRB approval was sought or that the institution's IRB was notified and rendered a conclusion that such approval was not needed.

A reviewer commented on the draft
In the abstract section, it would be good to include some of the preliminary findings. The author provided an excellent overview and description of the research study with ample quantitative data to support his/her conclusions and recommendations.

A reviewer commented on the abstract
This type of work is "routine" and conveys nothing new. We all have been doing this as a part of our responsibilities. This is not considered research or scholarship. ………. Routine Projects, Report Writing, Senior Design Capstone Courses, Project Management Techniques ……… These are all part of 4 year engineering education establishment. You say: "Students spent the first 9 weeks of the course following experimental procedures and writing lab reports." Our students do this as a routine in most of their engineering courses for all the 15 weeks. Senior Design is a course ….. Full Year … Two semester long. You have not accomplished anything of significance. Hopefully you will provide some data collection, graphs, analysis, inference, conclusions, ideas for improvement ……… Benchmark Institutions that have accomplished similar activities ….. etc. The abstract needs to be re-written to conform to ASEE guidelines. I am not at all impressed. Poor Show.
