__NOTOC__&lt;br /&gt;
The article &amp;#039;&amp;#039;Educational Development and Developmental Research in Mathematics Education&amp;#039;&amp;#039; was written by [[Koeno Gravemeijer]] and published in the &amp;#039;&amp;#039;[[Journal for Research in Mathematics Education]]&amp;#039;&amp;#039; in 1994. It is available from JSTOR at http://www.jstor.org/stable/749485.&lt;br /&gt;
&lt;br /&gt;
== Abstract ==&lt;br /&gt;
&lt;br /&gt;
In light of anticipated changes in mathematics education, an alternative for the well-known &amp;quot;research-development-diffusion&amp;quot; model is presented. It is based on an integration of curriculum research and design embedded in &amp;quot;educational development.&amp;quot; In this context curriculum development is described as purposeful and sensible tinkering. It is argued that the theory production implied in this process may be exploited in &amp;quot;developmental research.&amp;quot; However, developmental research is not yet well established as a research discipline. The core of this article is an effort to explicate the characteristics of developmental research and to discuss its methodological aspects.&lt;br /&gt;
