Very rarely has anyone in the workshop had a specific course about grading during a faculty training or credentialing program.6 ● Typical sequence of course activities that results in scores or grades in a gradebook, especially in higher education STEM courses.● There is extensive research demonstrating that retrieval practice, the practice of retrieving knowledge from memory, reflecting on that knowledge, and interleaving practice of that knowledge with other topics is effective at making knowledge stick. Known as “the testing effect”, research has shown that a number of successful retrievals are required to give a

rather than a true reflection of student summer activitypreference. The largest samples, juniors and seniors in both years, show an increasing number ofstudents who report only completing military activities which corresponds with standard trainingtimelines for ROTC students. These training camps take up a substantial portion of the summer,thus preventing students from participating in an engineering internship. Though one could statethat military training is an internship for students who will pursue military careers aftergraduation. When looking at the same student level across two years (e.g. comparing 2022juniors to 2023 juniors), we see inconsistent ratios of summer activities. However, when trackinga cohort between years there is more

Reflecting on the past decade since the course was introduced, both cadets and thedepartment have benefited from the course, both in unanticipated ways. For the cadets, thecourse has developed into a pre-capstone experience.

. One motivational factor is for non-engineering professors to be connected withengineering students whose capstone project aligns with an area of research being studied by theprofessor. While many engineering students choose to move on to industry after graduating,some choose to stay for a post-graduate degree. The capstone projects are often reflections of theinterests of the students. If there is an opportunity for a group of students to work with a non-engineering professor, then the students could not only expand their interest in amultidisciplinary field but also learn about the professor's work and expertise. In addition, theprofessor would also have opportunities to have the multidisciplinary capstone project involvethe development of

This is an interesting reflection of the academicpapers the LLM was trained on, as published papers rarely have negative results presented, sothe LLM tries to reframe every failure as a success because that is what it interprets as the trend.If tasked with creating documents without a predefined structure LLMs tend to produce text thatcan be excessively verbose, self-referential, and self-aggrandizing.

Some of those papers indicated that the literature onbridge programs was scant, despite the wealth of papers on the topic. In contrast, the literature ongraduate bridge programs is far less extensive and can actually be considered to be lacking. Thismay reflect, to some extent, both a lack of such programs and a lack of research on them.

There is evidence that educational interventions that “encourageexperiential learning, reflection, group work, active learning, and decision-making are generallymore effective in promoting moral judgment than those that use more traditional pedagogies”(see p. 404-405 in[10]).
