Practical Guidelines to Redesign Introductory Chemistry Courses Using a Flexible and Adaptive Blended Format

Incorporation of increased flexibility and adaptivity in courses can support freshmen with taking responsibility for their learning process. This is especially beneficial in the case of chemistry courses given their typically abstract nature and associated need for engaging in practice and higher order thinking. Blended learning can be used to achieve course flexibility and adaptivity, and increased student engagement. Adopting blended learning requires teachers to reconsider and redesign their course setup. The willingness for this will largely be dictated by perceived practicality, however. To this end, our aim is to develop practical redesign guidelines for flexible blended learning. Such guidelines need to be instrumental, congruent, and of 'low cost' for a teacher. The resulting four guidelines were fine-tuned in two phases over 5 years using two introductory chemistry courses and incorporated various blended learning elements, such as slide-cast lectures, live lectures, formative in-cast multiple choice questions, tutorials, formative electronic tutorial questions, and student voting on the course schedule. The outcome of our multiyear endeavor was positive and sustainable by all metrics used, including online engagement by students, learning outcomes, and student evaluations. The teachers in phase II largely embraced the guidelines emerging from phase I, and in their course experienced them predominantly as practical while limitations were also identified. We hope that our guidelines and experiences can provide fellow teachers with a blueprint for practical incorporation of flexibility and adaptivity using blended learning in their chemistry courses.

Automated summary

Incorporating increased flexibility and adaptivity in courses can help freshmen take responsibility for their learning process, especially in the case of chemistry courses. Blended learning can enhance student engagement, but requires teachers to reconsider and redesign their course setup, largely depending on perceived practicality.
