This paper presents a sequence of computer-based activities aimed at achieving an intuitive understanding of the ideas and concepts underlying the Fundamental Theorem of Algebra. Deductive proofs to support students' empirical investigations are also discussed. (LZ)

Presents activities which highlight major concepts of linear programming. Demonstrates how technology allows students to solve linear programming problems using exploration prior to learning algorithmic methods. (DDR)

Discusses a method of implementing the computer algebra system DERIVE for diagnosis and remediation of basic difficulties in mathematics. Learning activities for junior high school students were developed, each directed at a different area of difficulty. The basic strategy implemented in these activities is replicating and completing examples.…

Discussed is the classroom suitability of an open learning computer microworld centered around families of quadratic equations that provides a framework for exploring questions about parabolas to establish the link between the graphical and the algebraic representations of quadratic equations. (JJK)
