Python Programming for the Humanities by Folgert Karsdorp

Having just finished teaching a course on Big Data and Text Analysis where I taught students Python I can appreciate a well written tutorial on Python. Python Programming for the Humanities by Folgert Karsdorp is a great tutorial for humanists new to programming that takes the form of a series of Jupyter notebooks that students can download. As the tutorials are notebooks, if students have set up Python on their computers then they can use the tutorials interactively. Karsdorp has done a nice job of weaving in cells where the student has to code and Quizes which reinforce the materials which strikes me as an excellent use of the IPython notebook model.

I learned about this reading a more advanced set of tutorials from Allen Riddell for Dariah-DE, Text Analysis with Topic Models for the Humanities and Social Sciences. The title doesn’t do this collection of tutorials justice because they include a lot more than just Topic Models. There are advanced tutorials on all sorts of topics like machine learning and classification. See the index for the range of tutorials.

Text Analysis with Topic Models for the Humanities and Social Sciences (TAToM) consists of a series of tutorials covering basic procedures in quantitative text analysis. The tutorials cover the preparation of a text corpus for analysis and the exploration of a collection of texts using topic models and machine learning.

Stéfan Sinclair and I (mostly Stéfan) have also produced a textbook for teaching programming to humanists called The Art of Literary Text Analysis. These tutorials are also written as Jupyter notebooks so you can download them and play with them.

We are now reimplementing them with our own Voyant-based notebook environment called Spyral. See The Art of Literary Text Analysis with Spyral Notebooks. More on this in another blog entry.

Canadian Social Knowledge Institute

I just got an email announcing the soft launch of the Canadian Social Knowledge Institute (C-SKI). This institute grew out of the Electronic Textual Culture Lab and the INKE project. Part of C-SKI is a Open Scholarship Policy Observatory which has a number of partners through INKE.

The Canadian Social Knowledge Institute (C-SKI) actively engages issues related to networked open social scholarship: creating and disseminating research and research technologies in ways that are accessible and significant to a broad audience that includes specialists and active non-specialists. Representing, coordinating, and supporting the work of the Implementing New Knowledge Environments (INKE) Partnership, C-SKI activities include awareness raising, knowledge mobilization, training, public engagement, scholarly communication, and pertinent research and development on local, national, and international levels. Originated in 2015, C-SKI is located in the Electronic Textual Cultures Lab in the Digital Scholarship Centre at UVic.

DataCamp

I’ve been playing with DataCamp‘s Python lessons and they are quite good. Python is taught in the context of data analysis rather than the turtle drawing of How to Think Like a Computer Scientist. They have a nice mix of video tutorials and then exercises where you get a tripartite screen (see above.) You have an explanation and instructions on the left, a short script to fill in on the upper-right and interactive python shell where you can try stuff below.

FBI Game: What is Violent Extremism?

sheep

From Slashdot a story about an FBI game/interactive that is online and which aims at Countering Violent Extremism | What is Violent Extremism?. The subtitle is “Don’t Be A Puppet” and the game is part of a collection of interactive materials that try to teach about extremism in general and encourage some critical distance from the extremism. The game has you as a sheep avoiding pitfalls.

Geofeedia ‘allowed police to track protesters’

geofeedia
From the BBC a story about US start-up Geofeedia ‘allowed police to track protesters’. Geofeedia is apparently using social media data from Twitter, Facebook and Instagram to monitor activists and protesters for law enforcement. Access to these social media was changed once the ACLU reported on the surveillance product. The ACLU discovered the agreements with Geofeedia when they requested public records of California law enforcement agencies. Geofeedia was boasting to law enforcement about their access. The ACLU has released some of the documents of interest including a PDF of a Geofeedia Product Update email discussing “sentiment” analytics (May 18, 2016).

Frome the Geofeedia web site I was surprised to see that they are offering solutions for education too.

Professor Emeritus Seymour Papert, pioneer of constructionist learning, dies at 88

From Humanist and then MIT News, Professor Emeritus Seymour Papert, pioneer of constructionist learning, dies at 88. Papert was Piaget’s student and thought about how computers could provide children a way to construct knowledge. Among other things he developed the Logo language that I learned at one point. He also collaborated with the LEGO folk on Mindstorms, named after his book by that title.

When Women Stopped Coding

The NPR show Planet Money aired a show in 2014 on When Women Stopped Coding that looks at why the participation of women in computer science changed in 1984 after rising for a decade. Unlike other professional programs like medical school and law school, the percent participation of women when from about 37% in 1984 down to under 20% today. The NPR story suggests that the problem is the promotion of the personal computer at the moment when it became affordable. In the 1980s they were heavily marketed to boys which meant that far more men came to computer science in college with significant experience with computing, something that wasn’t true in the 70s when there weren’t that many computers in the home and math is what mattered. The story builds on research by Jane Margolis and in particular her book Unlocking the Clubhouse.

This fits with my memories of the time. I remember being jealous of the one or two kids who had Apple IIs in college (in the late 70s) and bought an Apple II clone (a Lemon?) as soon has I had a job just to start playing with programming. At college I ended up getting 24/7 access to the computing lab in order to be able to use the word processing available (a Pascal editor and Diablo daisy wheel printer for final copy.) I hated typing and retyping my papers and fell in love with the backspace key and editing of word processing. I also remember the sense of comradery among those who spent all night in the lab typing papers in the face of our teacher’s mistrust of processed text. Was it coincidence that the two of us who shared the best senior thesis prize in philosophy in 1892 wrote our theses in the lab on computers? What the story doesn’t deal with, that Margolis does, is the homosocial club-like atmosphere around computing. This still persists. I’m embarrassed to think of how much I’ve felt a sense of belonging to these informal clubs without asking who was excluded.

Computers in classroom have ‘mixed’ impact on learning: OECD report

The Globe and Mail and other sources are reporting that Computers in classroom have ‘mixed’ impact on learning. This is based on an OECD report titled Students, Computers and Learning: Making the Connection. The overall conclusion is that teaching is about the individual student and can’t be automated. Computers aren’t necessarily good for learning – they should be used for specific projects and used to teach real-world digital skills.

Students who use computers moderately at school tend to have somewhat better learning outcomes than students who use computers rarely. But students who use computers very frequently at school do a lot worse in most learning outcomes, even after accounting for social background and student demographics. (p. 3 of Report)

The Globe quotes Prof. Slotta of OISE to the effect that:

Technology is most effective in the classroom when it is used to develop skills similar to those that adults are using in everyday life, such as finding resources, critiquing arguments, communicating with peers, solving problems and working with data…

Skimming the report and the slide deck shows a complex picture where often countries like Japan have fewer computers in classrooms and do better on learning. Massive investment in computers like that of school boards who get laptops for every child doesn’t seem to lead to improvements in learning.

Put simply, ensuring that every child attains a baseline level of proficiency in reading and mathematics seems to do more to create equal opportunities in a digital world than can be achieved by expanding or subsidising access to high-tech devices and services. (p. 3 of Report)

The report also looked at loneliness and confirmed what parents have suspected,

Last but not least, most parents and teachers will not be surprised by the finding that students who spend more than six hours on line per weekday outside of school are particularly at risk of reporting that they feel lonely at school, and that they arrived late for school or skipped days of school in the two weeks prior to the PISA test.

The slide show prepared by Andreas Schleicher of the OECD suggest that there are larger questions about what sorts of skills should we be teaching in the coming age of automation. The second slide says “The kind of things that are easy to teach are now easy to automate, digitize or outsource.” A slide titled The Race between Technology and Education (title from work by Goldin and Katz) suggests that there is social pain when technology isn’t matched with education. The conclusion is that we need education for a world where many jobs can be automated. Just as the industrial revolution caused social pain in the form of dislocation and unemployment, so too could AI.
