The goal of this course wasto assist the students in their professional growth by providing the opportunity for opendiscussion (group and one-on-one settings) combined with constructive and positive feedback. The students guided the course content and were active participants in the class discussions. Course structure and content are presented along with the tangible outcomes. The perspectivesof the instructor and the students are presented side-by-side and offer a view of the effectivenessof a course geared towards increasing the students' career success. Self-examination anddiscussion brought to light many common issues and concerns faced by female engineeringstudents. Pre/post course

from oneperson’s experiences and not officially endorsed by any funding agency, they are focused toprovide encouraging and tangible advice on how new faculty can approach writing their firstproposals and get them funded.Introduction and Brief Background of the AuthorA key mentor (my mother) told me as I was growing up, “You don’t know what you don’t knowuntil you do know what you didn’t know.” This is apparently a slight misquote from LewisCarroll’s ‘Alice's Adventures in Wonderland’, but wise nonetheless. The issue is that when onedoesn’t know what they don’t know, they also don’t know what questions to ask or who to askthem of to find the answers they need to move forward. This is extremely true of beginningassistant professors in academia

This paper will focus on the latter case where graduate students are mentored bydepartmental faculty to learn teaching skills and to implement change within the department.The mentoring program at our university is informal and involves pairing a graduate student witha faculty member who is teaching the same course. The faculty and graduate student workclosely together to develop learning materials, design exercises, and exams. Typically, thegraduate student offers new ideas and learning exercises for the classroom that add new energyto the course. The faculty member provides guidance regarding the design of exam materials andwhat works well in the classroom.IntroductionMichigan Tech

These subtle opportunities are documented in the paper.ABET criterion and outcomes used to evaluate engineering and engineering technologyprograms now emphasize the use of standards, especially in the design process. This is a newchallenge for the engineering educator. Given that new engineering educators teach theirstudents about standards, it is necessary to become familiar with available information that mayhelp students as well as typical best practices for academic libraries. Acquiring access tostandards is the first step in using standards. The next step is to acquire skill and learn how tocritically read and apply them.The literature
