What Humanities Students Need College students To Know Concerning the Web: Various Paths for Various Endpoints

July 17, 2023 at 7:00 am

After we received the go-ahead to begin growing PCAS (see an update on PCAS here), I had conferences with a variety of liberal arts and sciences college. I’d ask college how they used computing of their work and what they needed their college students to learn about computing. Some college had urged that I speak to historical past professor, LaKisha Michelle Simmons. I met along with her in January 2023, and she or he modified how I considered what we have been doing in PCAS.

I advised her that I’d heard that she constructed web sites to clarify historical past analysis to most of the people, and she or he stopped me. “No, no —- my college students construct web sites. I don’t constructed web sites.” I requested her what she would love her college students to know in regards to the Web. “I might train them about how the Web works with packets and IP addresses. I might clarify about servers and domains.”

She stated no. She was much less concerned about how the Web labored. She had three particular issues she needed me to show college students.

  1. She needed college students to know that there are issues referred to as databases.
  2. That databases, if they’re designed properly, are straightforward to index and to seek out data in.
  3. Databases may very well be used to routinely generate Net pages.

Her record explains an enormous a part of the Net, however was fully orthogonal to what I used to be occupied with educating. She wasn’t asking me to show instruments. She needed me to show elementary ideas. She needed college students to have understanding a few set of applied sciences and concepts, and the scholars actually didn’t want IP addresses and packets to know them.

The necessary perception for me was that the computing that she was asking for was an affordable set, however completely different from what we usually train. These are superior CS concepts in most undergraduate applications, sometimes coming after lots of knowledge buildings and algorithms. From her perspective, these have been elementary concepts. She didn’t see the necessity for the stuff we usually train first.

I put studying targets associated to her factors on the whiteboards in my participatory design sessions. This confirmed up within the upper-right hand nook of the Justice class whiteboard — the most necessary studying goal. LaKisha gave me the training targets, and the humanities students who suggested me supported what she stated. This grew to become a prime precedence for our class Computing’s Impact on Justice: From Text to the Web.

Determining how

Throughout the summer season of 2022, a PhD scholar working with me, Tamara Nelson-Fromm, a gaggle of undergraduate assistants, and I labored at determining how one can obtain these objectives. We had to determine how one can have college students work with LaKisha’s three studying targets, with out difficult instruments. We have been dedicated to having college students program and assemble issues — we didn’t need this to be a lecture and concepts-only class.

We have been already planning on utilizing Snap, and it has built-in assist for working with CSV recordsdata. Undergraduate Fuchun Wang created an excellent set of blocks explicitly designed to look like SQL for manipulating CSV files. We used these blocks to speak about queries and database design within the class.

Tamara and I talked quite a bit about how one can make the HTML half work. I had promised our advisors that we might not require LSA college students to put in something on their computer systems within the intro programs. We talked about the potential for constructing a teaspoon language for Net web page improvement and to be used as templating instrument for databases, however I used to be anxious that we have been already throwing so many languages at the students.

Then it occurred to us that we might do that all with Snap. We built a set of blocks to represent the structure of an HTML page, like on this instance. Since we might outline our personal management buildings in HTML, we might current the items of a Net web page nested inside different blocks, to reflect the nested construction of the tags.

These final two blocks have been key. The view webpage block shows within the stage the primary 50 traces of the enter HTML. That’s necessary in order that college students see the mapping from blocks to HTML. The open HTML web page block opens a browser window and renders the HTML into it. (That was a tough hack to get working.)

This was sufficient for us to speak about constructing Net pages in Snap, viewing the HTML, then rendering the HTML within the browser. Right here’s a slide from the category. In deciding what laptop science concepts to emphasise, I used the work of Tom Park who studied student errors in HTML and CSS, and located that concepts of hierarchy and encapsulation have been a serious supply of error. These are necessary concepts throughout computing, so I used these as themes throughout the CS instruction — and the construction we might construct within the Snap block helped to current these concepts.

All of that collectively is sufficient to construct Net pages from database queries. Right here’s an instance — querying the billionaires database from Forbes for these from Microsoft, then making a Net web page kind letter asking them for cash.

We use these blocks in each of our lessons:

  • In the Justice class, college students use the HTML blocks to create a resume for a fictional or historic character in a homework task. In an even bigger mission, college students design their very own database of something they need, then create two queries. One ought to return 1-3 objects, and will generate a element web page for every of these objects. The second question ought to return a number of objects, and return an summary web page for that set of things.
  • In the Expression class, constructing an HTML web page is the final homework. They use type guidelines and must embed a Snap mission in order that there’s interactivity within the web page. Right here’s a slide from the category the place we’re exhibiting how including type guidelines modifications the look-and-feel of an HTML web page.

Various Paths to Various Endpoints

Mike Tissenbaum, David Weintrop, Nathan Holbert, and Tammy Clegg have a paper that I actually like referred to as “The case for different endpoints in computing training” (BJET link, UIUC repository link). They argue “for why we’d like extra and various endpoints to computing training. That many doable endpoints for computing training might be extra inclusive, simply and equitable than software program engineering.” I strongly agree with them, however I realized from this course of that there are additionally different paths.

Pc science sequences don’t often begin with databases, HTML, and constructing internet pages from database queries, however that’s what my humanities students advisors needed. Pc science often begins from algorithms, knowledge buildings, and writing strong and safe code, which our scholars did not want. Our PCAS programs are actually about different endpoints — we’re not making ready college students to be skilled software program builders. We’re additionally exhibiting that we will begin from a unique place, and introduce “superior” concepts even within the top notch. Computing training isn’t a sequence — it’s a community.
