요약Students' ability to reason about how quantities from dynamic situations change together-covariational reasoning-can support their sensemaking about real-world phenomena and abstract mathematical relationships. New types of digital mathematics tasks, like sketch-to-animation tasks, can be designed to support students' covariational reasoning and sense-making about how graphs represent covarying quantities. However, little is known about how the design of sketch-to-animation tasks affect students' covariational reasoning. Building on an existing framework for covariational reasoning, this study explores the differences in students' covariational reasoning when engaging with sketch-to-animation tasks that are numeric or non-numeric as well as open (i.e., multiple correct graphs through the coordinate plane) or well-defined (i.e., exactly one correct graph through the coordinate plane). A quasi-experimental study was conducted with 12 undergraduate Calculus 1 students to explore differences in their covariational reasoning across a sequence of sketch-to-animation tasks. Each student completed two 90-minute clinical task-based interviews in which they engaged with the sketch-to-animation tasks in the same order. The tasks were designed to support comparisons across one or both design features. The data consisted of audio, video, and screen recordings from the interviews. Data analysis entailed segmenting the data into sketch cycles, coding the observed level of covariational reasoning, and identifying patterns in how students' reasoning was similar or different across tasks that differed by key design feature. Differences in students' covariational reasoning were identified across student's initial sketching activity (i.e., prior to viewing the feedback animation) as well as across sketch cycles. A key finding was that students used different levels of covariational reasoning when engaging with numeric well-defined tasks compared to non-numeric well-defined tasks. In particular, students almost exclusively used coordination of values reasoning to plot points when engaging with the numeric well-defined tasks, whereas a wider variety of covariational reasoning levels were observed on the non-numeric well-defined tasks. A second key finding was that within observations of the same level of covariational reasoning, students utilized different strategies when engaging with well-defined or open tasks. Students who used coordination of values reasoning on numeric well-defined tasks searched through the animation to identify exact numeric values associated with critical moments in the situation and then plotted the corresponding points. In contrast, students who used coordination of values reasoning on non-numeric well-defined tasks reasoned about the location of coordinate points by making comparisons between magnitudes of quantities from the situation. These findings have implications for the design of digital mathematics curriculum that utilize animation-based graphing tasks to create opportunities for students to engage in covariational reasoning. In particular, the presence of numeric information and type of graphing task are design features that can impact students' reasoning and should be employed strategically depending on the pedagogical goals.
