+      Most of the concepts involved in software design directly map

+      example of structuring the information of a problem domain in Scala. In
+      <code>Modules.scala</code>, we show how straightforward it is to implement software modules with Scala classes. Last, in <code>Algorithms.scala</code>, we show how the
+      standard Scala collections can be leveraged to implement algorithms with
+      few lines of code.

+title: "Teach Programming with Scala"
+---
+
+Scala is more than a great programming language for building software.
+It is also a great tool for teaching programming!
+
+We are happy to announce that we have published a [new page][teach] on the
+website to explain the benefits of using Scala to teach programming, and to
+show a map of the universities who use Scala around the world (also shown below).
+
+{% include teachers-map.html %}
+
+*Teachers who use Scala in their course.*
+
+## Motivation
+
+Since Scala embraces several programming paradigms, it can be used to introduce
+many important concepts involved in computational thinking, from the most basic
+ones to the most advanced ones. It is suitable to teach programming to
+beginners, as well as to teach advanced software engineering courses.
+
+However, until now it was not easy to know which institutions use Scala. This
+information can be useful for students, PhD candidates, teachers looking for
+possible teaching connections, and companies interested in hiring new Scala
+developers.
+
+## Teach with Scala
+
+In the new [“Teach”][teach] page, we explain why we think Scala is a great tool
+for teaching programming, with evidence from several teachers around the world:
+
+- Scala supports multiple programming paradigms, which helps compare and contrast
+  different solutions to programming problems,
+- Scala is expressive: students can focus on the intent of their program without
+  being distracted by low-level concerns or syntactic noise,
+- Thanks to its type system, the Scala compiler helps the students to find bugs
+  before run-time,
+- Scala’s constructs are regular and principled,
+- Best practices are the norm (e.g., limited usage of `null`),
+- Scala runs on the JVM and on JS runtimes,
+- Scala’s ecosystem is large, and it can leverage the JVM and JS ecosystems,
+- Scala is versatile, it can be used to build many kinds of programs.
+
+The page also shows a map of teachers who use Scala in their courses.
+
+Finally, it provides several pointers to educational material.
+
+## Join the Movement
+
+We welcome all the teachers who use Scala to [contribute] to this page by:
+- adding themselves to the map of teachers,
+- refining the content,
+- providing testimonials, such as a single short sentence that summarizes
+  why you like using Scala to teach, or a sentence about a specific aspect
+  of the language that works well for you.
+
+Last but not least, we have set up a [community of teachers] where you can
+exchange best practices and work together on tools to improve your experience
+as teachers.

+The Scala Center operates the following Discourse forums:
 
  * **[users.scala-lang.org](https://users.scala-lang.org)**: The main forum for questions, discussions, and announcements about programming in Scala. Beginner questions are very welcome. Any question can and should receive a courteous and insightful answer.  (Replaces the old scala-user and scala-announce groups.)
 
  * **[contributors.scala-lang.org](https://contributors.scala-lang.org)**: For anything related to moving Scala forward; from Scala Platform library discussions, to Scala Improvement Process discussions, to development work on the Scala compiler, standard library, and modules. Core maintainers and open-source contributors are both welcome, as well as those who want to see what’s coming down the pipe and would like to be involved.  (Replaces the old scala-internals, scala-language, scala-debate, scala-sips, and scala-tools groups.)

 Discourse is an open-source forum and mailing list platform. You can participate via the web, or you can use "mailing list mode", where you receive posts in your inbox and can reply to them via email. The web interface provides statistics, upvoting, polls, and other features. Posts can be written in Markdown, including syntax highlighting.
 
 These forums are covered by the [Scala Code of Conduct](../conduct.html).
