<p class="MsoNormal">Dear MCLS Community,</p>

<p class="MsoNormal">I'm currently collecting data for a meta analysis looking into the effectiveness of spacing and retrieval for the retention of mathematics. In an effort to find unpublished grey literature, I would love to use your mailing list to inquire if
its members can help.</p>

<p class="MsoNormal"><span style="font-size:12.0pt;color:#212121">I am an ex-mathematics teacher currently undertaking a PhD in Psychology, at the University of York, under the supervision of Dr Silke Göbel and Dr Aidan J Horner. My project is focused on how
mathematical procedural complexity affects the efficacy of spaced retrieval practice. I am currently working on a meta-analysis synthesising the results of experiments that use the spacing or testing effect to improve the retention of mathematics material.
I am looking for grey literature or unpublished data to try to avoid the file drawer problem. <br>
