The passage describes the Author's impression of students participating in the "Upward Bound" program and it is generally favourable towards the program, without giving a more specific reason for this favourable opinion, it's more the author's personal impression.
Thus, we could say that the author has a positive bias towards the program.
In show and tell, everyone brings I something special to them. Like a stuffed animal or a rock or a trinket of some kind. Everyone takes time individually to talk about there item that they brought in. They would talk about what makes it special and why they chose to bring it. Hope this helps!
