<div class="imgblock">
    <img style="height: 130px;"  src="${resource(dir: 'images', file: 'unfav-unchecked.png')}" alt="Criteria" usemap="#p_icons" />
    <div class="smallblackarea">
            <map name="p_icons">
            <area shape="rect" coords="0,0,18,18" href="${createLink(controller: 'pedagogy', action: 'reloadPedagogyTab', id: imod?.id, params: [objectiveId: params.objectiveId, fav:'true', assign:'false'])}" title="Favorite" alt="Favorite" />
            **<area shape="rect" coords="90,0,126,24" href="${createLink(controller: 'pedagogy', action: 'reloadPedagogyTab', id: imod?.id, params: [objectiveId: params.objectiveId, pedtecID: "${ped.id}", fav:'false', assign:'true'])}" title="Assign" alt="Assign" />**

            </map>

Here is an explanation: http://blog.freeside.co/post/46587122020/groovy-gotcha-for-loops-and-closure-scope

Gstrings contain closures which get evaluated later in this case. In your example you can replace pedtecID: "${ped.id}" with pedtecID: ped.id or pedtecID: "${ped.id}" as String
