<p>Every field has its own key issues and methodologies. History and Literature, for example, are very different from Computer Science.  </p>

<p>However, it is in the interest of those in other fields to promote computational thinking. It is a skill that their students need and it can be a tool in their own work. However, to do this two things are necessary:</p>

<ul>
<li><p>First is to examine the current working practices in those other fields that use computational techniques in pursuit of their own goals. Literature, Science, Geography, History, Mathematics, the Social Sciences, all use computation for at least part of their normal work. This can be communicated to students and students can and should get practice in their use. </p></li>
<li><p>Second, and harder, is that it likely requires some collaboration, up to the level of team teaching, to bring good techniques to the fore for students. In other words, we in CS need to become servants to the other disciplines to help them deal with their own questions.</p></li>
</ul>

<p>Computational Thinking is a big deal in the US now. It can start very early in a kid's life. Piaget and The Montessori method took a shot at this long ago, with success. But it needs to go beyond just math, into, say, Algorithmics and Big Data. </p>

<p>I think it's detrimental, to both computer science and education in general, to think of "computing" as a separate topic from the more "traditional" subjects of reading, writing, arithmetic, art, etc.</p>

<p>Computer science permeates our lives. It's used in pretty much every subject and every job. And it's not just the surface-level "here's how to use Microsoft Word" stuff, so I urge you to get as far away from that type of lesson as possible.</p>

<p>Instead, think about the intersection of a particular subject and computer science. Some examples:</p>

<p><strong>English / Language Arts</strong></p>

<ul>
<li><p>Create <a href="https://en.wikipedia.org/wiki/Interactive_fiction" rel="nofollow noreferrer">interactive fiction</a> using something like <a href="https://twinery.org/" rel="nofollow noreferrer">Twine</a>.</p></li>

<li><p>Perform <a href="https://en.wikipedia.org/wiki/Sentiment_analysis" rel="nofollow noreferrer">sentiment analysis</a> between different works, or between two characters.</p></li>
<li><p>Instead of writing a research paper, have students edit a Wikipedia article.</p></li>
</ul>

<p><strong>Social Studies</strong></p>

<ul>
<li><p>Find an interesting data set and use <a href="https://en.wikipedia.org/wiki/Data_visualization" rel="nofollow noreferrer">data visualization</a> to tell a story about a social issue you believe in.</p></li>
<li><p>Use the <a href="https://developers.google.com/maps/documentation/javascript/" rel="nofollow noreferrer">Google Maps API</a> to visualize some geospatial data, or to highlight geographic issues.</p></li>
<li><p>Discuss projects like <a href="https://info.internet.org/en/" rel="nofollow noreferrer">internet.org</a> or <a href="https://x.company/loon/" rel="nofollow noreferrer">Project Loon</a>. What impacts would they have on developing countries?</p></li>
<li><p>Research how technology has been used to help with natural disasters, refugee crises, and terrorist attacks. What are the privacy concerns of different affected groups?</p></li>

</ul>

<p>None of the above require any advanced knowledge of computer science to at least dip your toes into the water. As a CS educator, you might volunteer to "guest lecture" the class, give them a basic demo, and have them work on some basic projects that introduce the above concepts.

<p>The real point is that there is no shortage of intersection between computer science and other fields. It's all over the place! Just take examples from real life, and think about the most bite-sized introduction you can come up with. Show that to the students, and you'll have a bunch of <em>"oh, I didn't realize programming could be so interesting!"</em></p>

@ctrl-alt-delor I don't think it's "using computer to teach other subjects" at all. I think it's finding the intersection of computer science and other subjects, which is where a lot of interesting (and lucrative) research is happening right now. Getting students who are already interested in other subjects thinking about how computer science helps them with their interests is a good thing for everybody involved, imho.

<p>In the UK we are also asked to include computing across the curriculum, in the same way that we are asked to include literacy and numeracy across the curriculum ( spelling, punctuation, grammar, reading, graphs, correct use of arithmetic and mathematical concepts).</p>

<p>Teachers often deal with this by doing a lesson in the computer room, using MS-Word; Using I-Pads, or searching for stuff with Google. This is the “we have to use a computer” panic. But it is not very educational</p>

<p>This has not always gone well: often a negative or neutral impact on computing, and if to much pressure is put on teachers to do this, then also a negative affect on the other subject as well. This is because most teachers are not computer science or IT teachers (I have heard some say “the pupils know more than I do”).</p>

<p>So what can be done in other subjects, not to just use computers or to try to give experience of computers to the pupils, but to teach an aspect of computer science or IT whilst still remaining within their subject's specialty.
