In one task, students set up an integral for the magnetic flux through a square loop. A second task asked students to set up an integral to solve for the electric field from a circular sheet of charge. Analysis identified several treatments of the differential area: (1) a product of differential lengths, (2) a sum of differential lengths, (3) a product of a constant length with differential length in one direction, (4) a derivative of the expression for a given area, and (5) the full area.<\/p>\n<p>Physics Education Research Conference 2017<br \/>\nPart of the PER Conference series<br \/>\nCincinnati, OH: July 26-27, 2017<br \/>\nPages 356-359<\/p>\n<p>DOI: 10.1119\/perc.2017.pr.084<\/p>\n<p>Link to UMaine PERL article archive:\u00a0<a href=\"http:\/\/umaineperl.blogspot.com\/2018\/03\/schermerhorn-thompson-on-determining.html\">Schermerhorn Thompson on determining differential area elements<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Student determination of differential area elements in upper-division physics Benjamin P.
