Canvas <code>Quiz<\/code> question type &#8220;formula question&#8221;).<\/li><li>Vary values and make <em>small variations on the wording and pictures of the tasks<\/em> using different versions of the same question randomly from a Canvas question bank. Use one question bank per task.<\/li><\/ul>\n\n\n\n<p><\/p>\n\n\n\n<p>The result? The teachers in the example write: <em>&#8220;Because each task differed from student to student, a higher reliability for the examination was achieved. It is more difficult to dismiss plagiarized tasks (where students &#8220;happen&#8221; to use the same value) as typos as there are several values that &#8216;accidentally&#8217; coincide.<\/em>&#8220;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"link\">Link<\/h3>\n\n\n\n<ul class=\"wp-block-list\" id=\"block-9bb0f16e-0605-47c4-a15f-0dd49adfec44\"><li><a href=\"https:\/\/intra.kth.se\/en\/utbildning\/examination\/exempelbank-examination\/examination-med-bra-slumpade-varden-1.1030663\">Examination with random values<\/a><br>KTH, Example bank for examination arrangements<\/li><\/ul>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>KTH&#8217;s unit for educational support describes an examination plan regarding numeracy.
