Abstract
This paper details an inquiry-based approach for teaching the basic notions of rings and fields to liberal arts mathematics students. The task sequence seeks to encourage students to identify and comprehend core concepts of introductory abstract algebra by thinking like mathematicians; that is, by investigating an open-ended mathematical context, identifying patterns, and venturing conjectures. A sequence of open-ended instructional tasks that aim to capitalize on students’ prior experiences with equation solving is provided along with notes and sample student responses for prospective instructors.
Notes
1 For more information on guided reinvention, see Gravemeijer [Citation4]. For more information about similar instructional sequences in abstract algebra, see Larsen [Citation5] (for group theory) and Cook [Citation1] (for ring theory).
2 If the instructor plans to compare zero-divisors across domains (or, indeed, formally name the term “zero-divisor”), the students must eventually come to terms with 3 × 4 = 0. Such explorations are not included in this task sequence. The point of the above comment, then, is that the identification of the modulus with zero need not be done immediately.
