@Peter That seems like a better question to me. Is there support for any particular set of criteria? (I'm actually not aware of anything in this regard)

Q: Resources for the Praxis CS Test

cryptic_starCurrent middle school/high school teachers in my state who want to obtain an additional license to teach computer science (notably AP CSP/CS A) must pass the Praxis computer science test. I'm looking for study materials, particularly in two areas: Additional practice tests that are aligned with...

high-school resource-information praxis

@Peter I don't understand the need, since this is HS. Do you need requirements for admission? Why? Are you overwhelmed? Do other HS study areas have admission requirements? Help me here.

I'm also surprised that there isn't already a course (or part of one) that every student must take. Performance in such a course would be a good indicator, I'd hope.

The overall grade point average should be sufficient, in my opinion.
You could make-up an aptitude test for prospective students.

I would think that desire is the best indicator of success. Ganas. Go watch Stand And Deliver again.

Q: What are the advantages/disadvantages of teaching how to implement Nodes, Linked Lists, Stacks, and Queues before showing built-in implementations?

Java JiveI'd like to introduce my students to Nodes and then require them to implement their own Linked Lists, Queues, and Stacks before showing them that their language (C#) provides implementations of these data structures. I suppose my motivation is that they will 1) understand better how these structu...

@JavaJive's new question needs some votes. It has some great answers already.

Ok. It is now HNQ. I think @JavaJive has a very high percentage of questions going HNQ. Maybe not all, but most, I think. Congrats.
However, my full week without rep got ruined, I guess. Bummer.
I feel like I sacrificed for the team by answering. ;-)

@Buffy Yes. All AP courses at my HS have some form of application; they are not open to just anyone who registers. They tend to require some prior level of academic achievement. Moreover, applications outnumber the number of seats available in the course, so some mechanism is necessary to weigh applications against each other.
@Buffy At least in my state, our HS grad requirements relate to what the public university system sets as admission requirements. CS is absent from this list.

Sounds like the university CS department is reluctant to set such "standards"?

I'm missing all the HNQ goodness, mostly because the important things have already been said.

I want to make sure I use some terminology correctly. Would you agree that implicit typing is a property only of statically typed languages? I have had students say in presentations that "x = 1" in Python is an example of implicit typing. I don't think it is, because the variable x does not have a type, only values do.

Perhaps, they are confusing it with the idea of different types of variables?

Stack Overflow Isn’t Very Welcoming. It’s Time for That to Change.
Jay Hanlon on April 26, 2018

Let’s start with the painful truth:

Too many people experience Stack Overflow¹ as a hostile or elitist place, especially newer coders, women, people of color, and others in marginalized groups.

Our employees and community have cared about this for a long time, but we’ve struggled to talk about it publicly or to sufficiently prioritize it in recent years. And results matter more than intentions.

Now, that’s not because most Stack Overflow contributors are hostile jerks. The majority of them are generous and kind. Sure, a few are…  just generous, I guess? But our active users regularly express thei …

@EllenSpertus In python variables don't have type and can refer to any value regardless of type. Hence dynamic typing. Values have type and once created can never change their type. In ML, variables have type but it doesn't usually need to be specified as the compiler can infer the type in most situations. But ML is strongly typed. Once the compiler infers the type of a symbol it can't be changed (in that scope).
@s.patroller My first experience with trying to contribute to SO was very disappointing. It seemed to reek of testosterone. It isn't welcoming of newbies at least and there is a lot of impatience with people who aren't in the clan.
@BenI. I struggled a bit trying to come up with something useful to add to the first two answers, which were excellent. I persevered.

It is why I don't like to downvote new visitors. I'd rather close bad questions from newcomers than downvote. It is hard to arrive at a site with 101 rep and see it decay down to 70 if you say something that isn't very useful.
When you don't yet understand the culture. Like arriving in the Amazon and being met with poison arrows.
Stern looks are fine. Poison arrows, not so much.
Hmmm. I wonder if the Google has poison arrows like the Amazon. ;-)
