This article discusses student difficulties in grasping concepts from linear algebra. Using an example from an interview with a student, we propose changes that might positively impact student understanding of concepts within a problem-solving context. In particular, we illustrate barriers to student understanding and suggest technological…

Discusses certain transferable skills and a strategy for developing them via an intensive short course on mathematical modeling. Includes student reactions and comments on the course. Suggests that this course developed modeling as well as generic skills through teaching, learning, and assessment style. (Author/KHR)

Describes some continuous models for growth of the seaweed Macrocystis pyrifera. Uses observed growth rates over several months to derive first-order differential equations as models for growth rates of individual fronds. The nature of the solutions is analyzed and comparison between these theoretical results and documented characteristics of…
