It wasn&amp;#039;t until years later during a conversation with fellow instructional designer Sharolyn Barnhurst that I suddenly realized that instructional design methods and techniques might be better organized as the patterns of a pattern language than in the myriad of other ways they are commonly represented. From that conversation &amp;#039;&amp;#039;iPatterns.org&amp;#039;&amp;#039; was borne.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

He described his use of patterns in pattern languages in a &amp;quot;Child’s history of pattern languages&amp;quot; found on his website (n.d.) &lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

The new idea in the book was to organize implicit knowledge about how people solve recurring problems when they go about building things.&amp;#039;&amp;#039;&amp;lt;br /&amp;gt;&amp;lt;br /&amp;gt;&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

Sometimes the transition is marked not by just a door but by a change in elevation (steps, large, small, straight, or curved), or a shaded path, or through a court yard.&amp;#039;&amp;#039;&amp;lt;br /&amp;gt;&amp;lt;br /&amp;gt;&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td colspan=&quot;2&quot;&gt;&amp;#160;&lt;/td&gt;&lt;td class=&#039;diff-marker&#039;&gt;+&lt;/td&gt;&lt;td class=&#039;diff-addedline&#039;&gt;&lt;div&gt;&lt;ins class=&quot;diffchange&quot;&gt;&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

Patterns are easy to remember and set out as if-then propositions. The book gave 253 patterns about solutions that are known to work.&amp;#039;&amp;#039;&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td colspan=&quot;2&quot;&gt;&amp;#160;&lt;/td&gt;&lt;td class=&#039;diff-marker&#039;&gt;+&lt;/td&gt;&lt;td class=&#039;diff-addedline&#039;&gt;&lt;div&gt;&lt;ins class=&quot;diffchange&quot;&gt;&amp;lt;/blockquote&amp;gt;&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

These patterns fit into larger patterns, which in turn, eventually fit into &amp;#039;&amp;#039;&amp;#039;&amp;#039;&amp;#039;sequences&amp;#039;&amp;#039;&amp;#039;&amp;#039;&amp;#039;.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

He notes,&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td colspan=&quot;2&quot;&gt;&amp;#160;&lt;/td&gt;&lt;td class=&#039;diff-marker&#039;&gt;+&lt;/td&gt;&lt;td class=&#039;diff-addedline&#039;&gt;&lt;div&gt;&lt;ins class=&quot;diffchange&quot;&gt;&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

We were surprised though, when we found out computer programmers liked it, because it was about building not programming. But the programmers said, &amp;quot;this is great, it helps think about patterns in programming and how to write reusable code that we can call upon when we need it.&amp;quot;&amp;#039;&amp;#039;&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td colspan=&quot;2&quot;&gt;&amp;#160;&lt;/td&gt;&lt;td class=&#039;diff-marker&#039;&gt;+&lt;/td&gt;&lt;td class=&#039;diff-addedline&#039;&gt;&lt;div&gt;&lt;ins class=&quot;diffchange&quot;&gt;&amp;lt;/blockquote&amp;gt;&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

The current concept of object-oriented languages grew, in part, from Alexander’s concept of &amp;#039;&amp;#039;&amp;#039;&amp;#039;&amp;#039;pattern language&amp;#039;&amp;#039;&amp;#039;&amp;#039;&amp;#039; applied to computer programming.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

His description often provided both examples and counter examples as well as explanations about why and how the pattern should be implemented as described. He also included with his descriptions references to other patterns that could be parent, sibling, or child patterns&amp;amp;mdash;as well as &amp;quot;cousins&amp;quot; (patterns that are related, but not directly). &lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

Pattern languages describe frameworks or families of related systems.&amp;lt;/li&amp;gt;&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

&lt;tr&gt;&lt;td colspan=&quot;2&quot;&gt;&amp;#160;&lt;/td&gt;&lt;td class=&#039;diff-marker&#039;&gt;+&lt;/td&gt;&lt;td class=&#039;diff-addedline&#039;&gt;&lt;div&gt;&lt;ins class=&quot;diffchange&quot;&gt;&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

&lt;tr&gt;&lt;td colspan=&quot;2&quot;&gt;&amp;#160;&lt;/td&gt;&lt;td class=&#039;diff-marker&#039;&gt;+&lt;/td&gt;&lt;td class=&#039;diff-addedline&#039;&gt;&lt;div&gt;&lt;ins class=&quot;diffchange&quot;&gt;&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td colspan=&quot;2&quot;&gt;&amp;#160;&lt;/td&gt;&lt;td class=&#039;diff-marker&#039;&gt;+&lt;/td&gt;&lt;td class=&#039;diff-addedline&#039;&gt;&lt;div&gt;&lt;ins class=&quot;diffchange&quot;&gt;Ironically, one outcome of the marriage of pattern languages and computer science was programmer Ward Cunningham’s development of a “wiki,” a well-known form of web-based database that is user-editable, which he originally devised to house the Portland Pattern Repository. The idea is that pattern languages are just too large and complex for a single individual to do. Since computers are adept at handling large, complex data sets, what was needed was a way for many people to participate in the creation and maintenance (read: &amp;quot;editing&amp;quot;) of the data set.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td colspan=&quot;2&quot;&gt;&amp;#160;&lt;/td&gt;&lt;td class=&#039;diff-marker&#039;&gt;+&lt;/td&gt;&lt;td class=&#039;diff-addedline&#039;&gt;&lt;div&gt;&lt;ins class=&quot;diffchange&quot;&gt;&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td colspan=&quot;2&quot;&gt;&amp;#160;&lt;/td&gt;&lt;td class=&#039;diff-marker&#039;&gt;+&lt;/td&gt;&lt;td class=&#039;diff-addedline&#039;&gt;&lt;div&gt;&lt;ins class=&quot;diffchange&quot;&gt;The process of including many people in this kind of effort is now called &amp;#039;&amp;#039;&amp;#039;crowd sourcing&amp;#039;&amp;#039;&amp;#039;, and its most famous example is Wikipedia, a very large and growing crowd-sourced encyclopedia&amp;amp;mdash;and the most famous wiki in the world. (Coincidentally, this wiki is built on the same software as Wikipedia.)&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td colspan=&quot;2&quot;&gt;&amp;#160;&lt;/td&gt;&lt;td class=&#039;diff-marker&#039;&gt;+&lt;/td&gt;&lt;td class=&#039;diff-addedline&#039;&gt;&lt;div&gt;&lt;ins class=&quot;diffchange&quot;&gt;&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
