The stories shared were very powerful, demonstrating many opportunities lostby the panelist’s home institution. Mentoring was identified as a critical issue and a variety ofexamples were presented that showed the impact of both good and bad mentoring. Thepresentation and the Q&A both helped to motivate the Anti-Racism workshops being offered byIEC spring 2021.The next two sessions were organized and presented by Prof. Russ Korte of George WashingtonUniversity and IEC leadership.Session 6: Team Science Part 1 (October 2020) Teamwork and task work

The secondinterview explored their experiences in the Bridge program and their aspirations for their co-op.Interviews were professionally transcribed and pseudonymized.Data were analyzed using a narrative approach that includes multiple readings [19]. Themultistep process included reading for: familiarization with the transcripts, identifying contentsuch as individuals mentioned and major storylines, detecting identity of the participant andothers, and uses of CCW and funds of knowledge. After the readings, a narrative case waswritten for each participant.Quality was considered internally and externally.

implementing Project COMPLETE in high schools 4) A Q&A session intended to solicit feedback from the teachers and counselors about their specific concerns with teaching the curriculumIt is important to note that speaking responsibilities were divided up among the project’s collegeand high school representatives, which allowed workshop participants to hear about variousaspects of the program. For instance, a high school counselor shared about how to enroll studentsin courses and get them specific credit. Since every school has to navigate their version ofcurricula, credit, and state education priorities/incentives, this was an important topic to cover. Itwas also valuable for the workshop’s teacher participants to learn what the

But the rate of change of avariable can be accumulated or integrated to provide the total change; e.g., say, we are interestedin accumulating the varying charge, Q(t), flowing into a capacitor. The rate of change of chargeis the current through the capacitor, i(t). The total accumulated charge between times t1 and t2 is tobtained by the classic integration process Q =∫t 2 i(t) dt . No harm is done interpreting the 1accumulated charge as the area under the graph of i(t), if it

The effects of changingthe distribution from 10 to 50% will be discussed in the talk for the semester averages.As the semester progressed, comments appeared to be more randomly placed and less dialoguebetween students was occurring.
