SIGCSE 2018 Preview: Black Women in CS, Rise Up 4 CS, Community College to University CS, and Gestures for Learning CS

While I’m not going to be at this year’s SIGCSE, we’re going to have a bunch of us there presenting cool stuff.

On Wednesday, Barb Ericson is going to this exciting workshop, CS Education Infrastructure for All: Interoperability for Tools and Data Analytics, organized by Cliff Shaffer, Peter Brusilovsky, Ken Koedinger, and Stephen Edwards. Barb is eager to talk about her adaptive Parsons Problems and our ebook work.

My PhD student, Amber Solomon, is presenting at RESPECT 2018 (see program here) on a paper with Dekita Moon, Amisha Roberts, and Juan Gilbert, Not Just Black and Not Just a Woman: Black Women Belonging in Computing. They talk about how expectations of being Black in CS and expectations as a woman in CS come into conflict for the authors.

On Thursday, Barb is presenting her paper (with Tom McKlin) Helping Underrepresented Students Succeed in AP CSA and Beyond, which are the amazing results from the alumni study from her Project Rise Up effort to help underrepresented students succeed at Advanced Placement CS A. When Barb was deciding on her dissertation topic, she considered making Rise Up her dissertation topic, or adaptive Parsons problems. She decided on the latter, so you might think about this paper as the dissertation final chapter if she had made Rise Up her dissertation focus. Project Rise Up grew from Barb’s interest in AP CS A and her careful, annual analysis of success rates in AP CS A for various demographics (here is her analysis for 2017). It had a strong impact (and was surprisingly inexpensive), as seen in the follow-on statistics and the quotes from the students now years after Rise Up. I recommend going to the talk — she has more than could fit into the paper.

On Friday, my PhD student, Katie Cunningham, is presenting with her colleagues from California State University Monterey Bay and Hartnell College, Upward Mobility for Underrepresented Students: A Model for a Cohort-Based Bachelor’s Degree in Computer Science.  The full author list is Sathya Narayanan, Katie, Sonia Arteaga, William J. Welch, Leslie Maxwell, Zechariah Chawinga, and Bude Su. They’re presenting the “CSin3” program which drew in students from traditionally underrepresented groups and helped them earn CS degrees with remarkable success: A three year graduation rate of 71%, compared to a 22% four-year graduation rate, as well as job offers from selective tech companies. The paper describes the features of the program that made it so successful, like its multi-faceted support outside the classroom, the partnership between a community college and a university, and keeping a cohort model. The paper has been recognized with a SIGCSE 2018 Best Paper Award in the Curricula, Programs, Degrees, and Position Papers track.

On Friday, my colleague Betsy DiSalvo is going to present at the NSF Showcase some of the great work that she and her student, Kayla des Portes, have been doing with Maker Oriented Learning for Undergraduate CS.

On Saturday, my EarSketch colleagues are presenting their paper: Authenticity and Personal Creativity: How EarSketch Affects Student Persistence with Tom McKlin, Brian Magerko, Taneisha Lee, Dana Wanzer, Doug Edwards, and Jason Freeman.

Also on Saturday, Amber with her undergraduate researchers, Vedant Pradeep and Sara Li, are presenting a poster which is also a data collection activity, so I hope that many of you will stop by. Their poster is The Role of Gestures in Learning Computer Science. They are interested in how gesture can help with CS learning and might be an important evaluation tool — students who understand their code, tend to gesture differently when describing their code than students who have less understanding. They want to show attendees what they’ve seen, but more importantly, they want feedback on the gestures they’ve observed “in the wild.” Have you seen these? Have you seen other gestures that might be interesting and useful to Amber and her team? What other kinds of gestures do you use when explaining CS concepts? Please come by and help inform them about the gestures you see when teaching and learning CS.

AP Computer Science Demographics Report for 2015 completed #CSEdWeek

Barbara Ericson, with the help of Phil Sands at Purdue, has now finished tabulating the demographic data for AP Computer Science for 2015 — see link here.  We don’t yet have the statistical tests that Kevin Karplus asked for (see post here), but Barbara did list the percentage of Hispanic exam takers with their proportion of the population.

hispanic-exam-takers

Our blog posts on AP CS have been picked up by Audrey Watters in her 2015 Top Ed-Tech Trends summary, in a decidedly negative light.

I’ll look at the whole “learn-to-code” push in an upcoming post, but I will note here: “Nationally, 37,327 students took the AP CS A exam in 2014,” Mark Guzdial observed. “This was a big increase (26.29%) from the 29,555 students who took it in 2013.” “Barbara Ericson’s 2015 AP CS demographics analysis: Still No African-Americans Taking the AP CS Exam in 9 States.” And Code.org teamed up with the College Board: because everyone needs to learn to code and then hand over money to the College Board for an AP test on the subject. Boom.

We don’t analyze AP CS A in order to market for the College Board.  We analyze AP CS A exam demographics because it’s the only operational definition we have found of the state of computing education across the United States.  From our work in “Georgia Computes!” we know that AP CS A tracks closely all other computing education in Georgia.  AP CS A is a dipstick to get a sense for who’s in the high school CS population.

How many schools will honor the AP CSP attestation?

My Blog@CACM post this month is A Call to Action for Higher Education to make AP CS Principles Work. The Advanced Placement course on CS Principles becomes “real” this Fall 2016, and the first offering of the exam will be Spring 2017.  I expect that we in academic CS departments in the United States will soon be getting phone calls, “If we offer AP CSP and our students pass the exam, what will it count for at your school?”

When I talk to people who have worked on CSP about this issue, the question I get back in response is, “But there’s the attestation!”  Over 80 schools supported creation of the AP CS Principles course — see the list here.  The wording of the attestation varied by school, but makes these five points (taken from Larry Snyder’s page):

  1. It’s a substantive, important project — keep up the good work!
  2. We intend to give successful students credit at our school
  3. We intend to offer a comparable, content-rich course
  4. We intend to give successful students placement in a sequent course at our school
  5. [Optional] We are willing to have our school listed as supporting AP CS Principle

I don’t know.  My school currently has no plans for #2, 3, or 4, but we did sign the attestation.  (I’m working on coming up with a plan at Georgia Tech, but am not getting much traction.)  I don’t know about the status at other schools that signed the attestation.  I expect that Duke and Berkeley are going to follow-through, since they have done #3.  Some schools don’t give any or much credit for AP, so #2 may be out of the CS departments hands. I don’t know if there’s any legal requirement to follow through on the attestation.

Barbara Ericson’s 2015 AP CS demographics analysis: Still No African-Americans Taking the AP CS Exam in 9 States

Cursor_and_Still_No_African-Americans_Taking_the_AP_Computer_Science_Exam_in_Nine_States_-_Curriculum_Matters_-_Education_Week

Normally, this is the time of the year when Barb writes her guest post about the AP CS exam-taker demographics.  She did the analysis, and you can get the overview at this web page and the demographics details at this web page.

But before we got a chance to put together a blog post, Liana Heitin of EdWeek called her for an interview.  They did a nice job summarizing the results (including interactive graphs) at the article linked below.

Some of the more interesting points (from Liana’s article):

No girls took the exam in Mississippi, Montana, or Wyoming. (Though Montana had no test-takers at all, male included, this year. Wyoming, which previously had no students take the test, had three boys take the exam in 2015).

Hawaii had the largest percentage of female test-takers, with 33 percent.

The overall female pass rate went up 3 percentage points, to 61 percent, from the year before.

Twenty-four girls took the test in Iowa, and 100 percent of them passed.”You don’t usually see 100 percent passing with numbers that big,” said Ericson. “Maybe five out of five pass. But 24 out of 24 is pretty cool.”

No African-American students took the exam in nine states: Idaho, Mississippi, Montana, New Hampshire, New Mexico, North Dakota, South Dakota, Utah, and Wyoming. That’s better than last year, though, when 13 states had no African-American test-takers.

Notably, Mississippi has the highest population of African-Americans—about half of the state’s high school graduates last year were black, according to the Western Interstate Commission for Higher Education. Yet of the five AP computer science test-takers, all were white or Asian and male.

More Students Taking AP CS Exams, but WAY more taking AP Physics

Surprising result!  We knew that AP CS was growing quickly (see Code.org blog post), but AP Physics just took a giant leap forward.  I wonder why that is, and what we can learn from that.

The number of students taking the physics test doubled between 2014 and 2015. The College Board, the nonprofit that administers the AP program, said that represents the largest annual growth in any AP course in history.

Statistics worrying about losing ground to CS: Claim that CS isn’t worthy

The linked blog post below bemoans the fact that the AP CS is growing, perhaps at the expense of growth in AP Statistics.  AP Stats is still enormously successful, but the part of the post that’s most interesting is the author’s complaints about what’s wrong with CS.  I read it as, “Students should know that CS is not worthy of their attention.”

It’s always worthwhile to consider thoughtful critiques seriously.  The author’s points about CS being mostly free of models and theories is well taken.  I do believe that there are theories and models used in many areas of CS, like networking, programming languages, and HCI. I don’t believe that most CS papers draw on them or build on them. It’s an empirical question, and unfortunately, we have the answer for computing education research.  A recent multi-national study concluded that less than half of the papers in computing education research draw on or build on any theory (see paper here).

Though the Stat leaders seem to regard all this as something of an existential threat to the well-being of their profession, I view it as much worse than that. The problem is not that CS people are doing Statistics, but rather that they are doing it poorly: Generally the quality of CS work in Stat is weak. It is not a problem of quality of the researchers themselves; indeed, many of them are very highly talented. Instead, there are a number of systemic reasons for this, structural problems with the CS research “business model.”

Code.org grows CS Ed partnership to reduce the Babble in CS Ed

I wrote my May Blog@CACM post on the “Babble of Computing Education,” about the wide variety of perspectives, definitions, and cross-purposes going on in the US in computing education.  At the end, I talk about the new Code.org partnership with the College Board and how this may reduce the Babble — the definition of CS Principles will become Code.org.  Owen Astrachan, co-PI of the NSF CS Principles grant, and I have a bet for dinner and beer that we made on Facebook.  I predict that in the first offering of the AP CS Principles exam, more than 50% of the schools that teach CSP and send students to the exam will be using Code.org curricula.  He thinks that there will be greater diversity.

I don’t know how the new partnerships announced below fit into our bet.  BJC, PLTW, and other curricula are now going to be promoted by Code.org as their partners.  Will a school adopt BJC because Code.org recommends it?  I think that’s likely.  Will the school believe that they are adopting a curriculum out of Berkeley or a Code.org curriculum?  I expect the latter.  From schools’ perspective, all the eleven new partners will be Code.org curricula. The definition of CS Principles will become Code.org.  That’s not necessarily a bad thing — that may provide a corporate face that will assure administrators in schools who don’t know CS.

“Code.org’s courses already reach millions of students globally in grades K-8,” Partovi said. “But as we expand in high school, we work region by region, and we can’t do it all. We’re leading a movement and we need partners to help.”

When Code.org meets with school districts, it will now also highlight the new partnerships as alternative ways to teach computer science versus utilizing Code.org’s own programs.
