Assessments as Sites for Teacher Sensemaking About Epistemic Learning Goals in Science
Science Education, EarlyView.ABSTRACT Recent science education reforms aim to broaden allowable ways of knowing and learning in science classes. Doing so requires that we attend to and work to shift messages about useful ways to know and learn (i.e., epistemological messages) embedded in course designs and enactments.

Wear study of structured coated belts in advanced abrasive belt finishing [PDF]
Surface and Coatings Technology, 2015 Abstract Advanced belt finishing process is remarkably simple and inexpensive. The principle of operation is simple: pressure-locked shoes platens circumferentially press an abrasive coated belt on a rotating workpiece. This abrasive machining process reduces significantly surface irregularities subsequently improving geometrical quality and ...
