Although modeling is an integral process in applied mathematics, students rarely encounter modeling opportunities in their calculus courses. We introduce a laboratory experience as a starting point for calculus students to investigate multivariable functions. A layered system of coffee and milk serves as a physical model for temperature gradients…

This study examines the importance of interaction for second language (L2) acquisition by analyzing outcomes from two types of out-of-class activities. The study compared: (a) interactive homework, completed via text chat, and (b) individual homework, completed via independent writing. In a between-subjects design, participants in two…

In this article, we describe several role-playing exercises on acculturation and relevant cultural adjustment processes that we incorporated into Tomcho and Foel's classroom activity on acculturation, and we report data that examine subsequent changes in students' responses on pretest and posttest measures shortly after the activity and present…

We modified the Just-in-Time Teaching approach and developed a dual safeguard web-based interactive (DGWI) teaching system for an introductory physics course. The system consists of four instructional components that improve student learning by including warm-up assignments and online homework. Student and instructor activities involve activities…

The majority of students who took this general education undergraduate course in developing cross-cultural understanding at a state college in the northeastern United States reported that their level of cross-cultural competence and global awareness increased by the end of the course. The primary course objective was to help students better…

As highlighted by the National Math Panel Report (2008), consistent results from laboratory studies have demonstrated that interleaving worked examples with problems to solve improves learning for novices. The purpose of this work is to create materials and tests that can be used flexibly in classrooms and which employ worked examples interleaved…

Electronic reverse auctions are increasingly being used by firms to improve firm financial and operational performance. The described teaching innovation serves as a model for introducing electronic reverse auctions as a central element in a comprehensive negotiation exercise involving sales management and purchasing management students. Results…

Virtual environments can resolve many practical and pedagogical challenges within higher education. Economic considerations, accessibility issues, and safety concerns can all be somewhat alleviated by creating learning activities in a virtual space. Because of the removal of real-world physical limitations like gravity, durability and scope,…

Teaching about racism creates challenging issues for educators and students alike. Using experiential learning and a public-access curriculum to teach about racism and social inequality, graduate and undergraduate students participated in this elective course. The hybrid "minimester" course focused on affective responses to classroom activities,…

Ensuring that students spend time preparing for class has always been one of the challenges of teaching. Indeed, when students are given an assignment that they are required to do before coming to the next lecture--whether it be written exercises or just studying--one wonders how often they are actually doing it. There are many ways in which…
