Fig. 7From: Multiple-true-false questions reveal more thoroughly the complexity of student thinking than multiple-choice questions: a Bayesian item response model comparisona Relationship of multiple-choice (MC, blue circles) and multiple-true-false (MTF, orange circles) endorsement rates to option/statement attractiveness values across all questions among students not giving fully correct answers. b Response pattern from four representative MTF questions. The dashed line represents the proportion of students providing a fully correct answer (TFFF). The column labeled a represents the proportion of students that answered correctly the true statement, and the columns labeled b–d represent the proportion of students that answered correctly each false statementBack to article page
