Both groups were given similar collaborative tasks, but only the students in the treatment group were given access to a set of 3D manipulatives. Pre- and post-assessments were administered to measure student achievement and confidence on the tasks comparing results for the control and treatment groups as well as for the male and female students. No statistically significant differences in student achievement were detected for the control or treatment group or by reported gender on either an immediate posttest or a delayed posttest. There was statistical significance in confidence after engaging in the 3D manipulative tasks favoring the treatment group. However, further inspection by gender revealed that while males in the treatment group were more likely to report higher confidence ratings than males in the control group, the reverse was true for females.}, journal={Investigations in Mathematics Learning}, publisher={Informa UK Limited}, author={Paul, Stepan and Grundmeier, Dusty and Moore-Russo, Deborah}, year={2024}, month={Feb}, pages={1–20} } @article{moore-russo_martínez-planell_stanhope_seeburger_paul_vandieren_2024, title={Multivariable Calculus Instructors’ Reports of Resource use}, url={https://doi.org/10.1007/s40753-024-00243-5}, DOI={10.1007/s40753-024-00243-5}, journal={International Journal of Research in Undergraduate Mathematics Education}, author={Moore-Russo, Deborah and Martínez-Planell, Rafael and Stanhope, Shelby and Seeburger, Paul and Paul, Stepan and VanDieren, Monica M.}, year={2024}, month={Dec} } @inproceedings{martinez-planell_moore-russo_seeburger_stanhope_paul_2024, title={Resource Use and Student Engagement in Multivariable Calculus}, url={http://sigmaa.maa.org/rume/Site/Proceedings.html}, booktitle={SIGMAA on RUME Annual Conference}, author={Martinez-Planell, Rafael and Moore-Russo, Deborah and Seeburger, Paul and Stanhope, Shelby and Paul, Stepan}, year={2024}, month={Feb} } @article{chen_delp_paul_2023, title={Manipulative calculus: active learning with 3D models}, DOI={10.1090/psapm/079/00714}, abstractNote={Manipulative Calculus is a curriculum development project focused on creating active learning\index{active learning} lessons in calculus courses centered around digitally fabricated 3D models that we put into students’ hands.
