The laboratory experiment objectives were non-prescriptive allowing the students to develop their own methods for conducting the experiments. \u0000During the spring of 2020, we had all of the IBL course structure in place, and it aided significantly in our shift to “virtual classrooms” after Rice University closed its campus in the wake of the COVID-19 pandemic.  By re-designing the undergraduate lab course using IBL principles, we fortuitously gave ourselves built-in flexibility to go to emergency virtual format in Spring 2020, and virtual format in Fall 2020.  This also allows us to go hybrid or full in-person in the future.  We provided students with laboratory data so that they could continue the analysis at home.  However, students were not able to conduct appropriate experimentation, which is one of the key learning objectives for the laboratory courses.","PeriodicalId":72557,"journal":{"name":"Chemical engineering education","volume":"2005 1","pages":"85-85"},"PeriodicalIF":0.0,"publicationDate":"2021-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86870283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
