This study aims to establish the level at which University of Nebraska-Lincoln students reason with simple relationships in the context of cellular respiration at the levels of glycolysis, Krebs cycle, and electron transport chain. These processes are component processes of cellular respiration and each has multiple inputs and outputs. 633 student consented for this study, from which 18 student models were randomly selected, processed, and analyzed. Classroom observations were used to determine structures and relationships that were inputs and outputs to the three processes. In their models, students did not include different numbers of input or outputs when describing glycolysis, …

Question format is an important consideration when designing instruments to gauge student comprehension. In many lecture-style courses, instructors must decide how to effectively test a large group of students. Two common types of question formats used for introductory biology exams are free-response (FR) and multiple-true/false (MTF). FR questions include a question prompt which students respond to with essay-style answers. Conversely, MTF questions include an opening question stem with accompanying statements to be marked as either true or false. The goal of this study was to determine the advantages and disadvantages of FR and MTF question formats for assessing student comprehension …
