What went well

What could be improved on

Team Leads

Got through all material; explained each concept/component very well and provided examples; mentor present to field questions, provided further explanations, + connected what was being taught to build season + things they do at work

Engage + ensure understanding of rookies (they only participate via chat and rarely at that); Future suggestions: ask more clarifying questions to make sure rookies are present + comfortable w/ material; when mentor is present, urge rookies to ask questions; turn on cameras, so rookies are more comfortable in doing the same

Rookies

Liked talking about regulator + experimenting in tinkercad

Wished it was more fun

• Understanding of material: 4

  • (1= Nothing, 5= Understood everything; from rookie's perspective)

What went well

What could be improved on

Team Leads

A lot of participation; having cameras on worked well; also got started on Ultrasonic sensor project, got ultrasonic sensor circuit prototypes for electrical members working, and got new pins

If had to redo meet, would add short review session at the end

Rookies

Liked assembling Ultrasonic sensor and doing it in real life

Disliked trying to find tiny resistor; wished it was more entertaining

• *Note: Team leads thought this weeks meeting was the best out of all the other meetings
