Globals Breaks And Returns, oh my

Never use global variables Never break out of a loop These are two "best practices" that are frequently touted in early CS classes both at the high school and college level. They came up a couple of times yesterday. Once in the Facebook APCS-A teachers group and once on Alfred Thompson's blog. Alfred post was topically on global variables.

When the students know more than the teacher

We've heard it many times with computer science - "the kids know more than the teacher." On the one hand, the truth is that this isn't so much the case. Kids might use computers all the time but they don't necessarily know much about them or about computer science (link 1, link 2). Then you have students who think they know all about CS but really don't. They might have picked up a bit of coding somewhere but more often than not, the knowledge is pretty superficial.

Fall 2018 HS CS Tour

I've written before about why Hunter College CS is so important for NYC and I've been working hard to develop our Daedalus Scholars honors CS program - a program in which students receive a scholarship along with all sorts of special opportunities to add on to their in class CS education. The program and Hunter CS as a whole have made a lot of progress over the past two years and each year I roll out new special activities and events for my honors students.

CS vs CT vs Coding

There's been a lot of buzz recently concernting Computational Thinking (CT) vs Computer Science (CS) vs Coding / Programming on the interwebs. Some of the questions and concerns that I've seen recently include: What is CT?? Will rich schools get CS and poor only CT? Will rich schools get CS and poor on coding? The first question is a big one and as a community we haven't answered it yet.
