Science, technology, engineering, and mathematics disciplines commonly illustrate 3D relationships in diagrams, yet these are often challenging for students. Failing to understand diagrams can hinder success in STEM because scientific practice requires understanding and creating diagrammatic representations. We explore a new approach to improving student understanding of diagrams that convey 3D relations that is based on students generating their own predictive diagrams. Participants’ comprehension of 3D spatial diagrams was measured in a pre- and post-design where students selected the correct 2D (...) slice through 3D geologic block diagrams. Generating sketches that predicated the internal structure of a model led to greater improvement in diagram understanding than visualizing the interior of the model without sketching, or sketching the model without attempting to predict unseen spatial relations. In addition, we found a positive correlation between sketched diagram accuracy and improvement on the diagram comprehension measure. Results suggest that generating a predictive diagram facilitates students’ abilities to make inferences about spatial relationships in diagrams. Implications for use of sketching in supporting STEM learning are discussed. (shrink)

De ce este importanta familia? Care este statutul moral al copiilor si cine are ce responsabilitati fata de ei? Ce este consimtamintul si care sint conditiile in care este valid? Care ar trebui sa fie rolul religiei in dezbaterile publice dintr-o societate democrata? Cum ar trebui sa fie gestionate inegalitatile sociale create de mosteniri? Ar trebui ca vaccinarea sa fie obligatorie? Este legitim sa fie cenzurate anumite forme de discurs? Avem datoria sa votam si, daca da, care sint considerentele morale (...) care ar trebui sa ne ghideze votul? In aceasta carte analizam teme precum cele de mai sus, folosind atit metodele filosofiei analitice, cit si abordari interdisciplinare. Printr-un efort colectiv, conectat la spatiul romanesc, ilustram felul in care etica aplicata poate contribui la intelegerea problemelor morale ale lumii actuale. Speram ca textele incluse in aceste pagini sa fie de folos in reflectia asupra moralitatii alegerilor noastre individuale si colective. (shrink)
