The coronavirus (COVID-19) outbreak mandated a rapid transition to online classes with little warning. Previous literature studying the effects of this sudden shift demonstrated enormous impacts on instructors and students. However, the details concerning science instructor assessment choices during this time are less clear. We asked biology instructors to reflect on the changes they made to their assessments of student learning during the emergency transition to remote instruction in spring 2020 and whether the potential changes were motivated by equity concerns. We also asked instructors to describe the assessment changes they intended to keep in future semesters. Through quantitative and qualitative analyses, we found that instructors removed forms of assessment more often than they added them, and the most common changes included how instructors administered exams and engaged students through participation. Instructors reported that equity concerns motivated their decision-making, particularly their concern over students' ability to access learning resources. Instructors indicated they would keep many of the changes they made in response to the shift to online learning. Our research shows that the pandemic dramatically altered how instructors assessed students in biology, but equity-based decisions leading to lasting change may be one positive outcome for future students.

Student-study behaviors and metacognition are predictors of student-academic success. However, student metacognitive evaluation of their own study habit behavior use has been largely unexplored. To address this gap, we gave students enrolled in three different Biology courses (n = 1140) a survey that asked them to identify the study behaviors used to prepare for their first and third exams and to appraise the effectiveness of each behavior. We observed that, across all courses, students used different counts of active- and passive-study behaviors. However, there were no differences in performance across courses, and the use of effective (i.e., active) study behaviors resulted in improved exam performance for all students, regardless of course, while the use of ineffective (i.e., passive) study behaviors had no significant impact on exam performance. Finally, our qualitative analysis revealed that students across all courses demonstrated similar ability in identifying effective-study behaviors, but students could not explain why those behaviors were effective. Taken together, our study demonstrates that students use various study behaviors to prepare for exams without understanding their effectiveness. We encourage instructors to structure their courses to promote the development of metacognitive evaluation and effective-study behaviors.
