Presents a study using a module of work based on a graphing calculator that provided an environment where students could experience some aspects of variables and begin to build an understanding of them. Graphing calculators proved to be an instrument for achieving significant improvement in student understanding, which had often proved difficult…

Interviews 53 sixth grade students individually in an attempt to discover whether wrong interpretations of the algebraic structure found in an algebraic context occurs in a purely numerical context. Concludes that students' difficulties with the algebraic structure were also found in purely numerical contexts. (Contains 27 references.) (Author/ASK)

Algebraic calculators with symbolic manipulation capabilities are tools in some classrooms for 14-19 year olds, and their use in learning and teaching mathematics is likely to increase over time. Explains the reports of government-initiated working groups that consider the implications of their use in academic mathematics examinations for…

The factor structure of three commonly used measures of mathematics anxiety was examined using a sample of 323 undergraduates in an algebra class. Six oblique factors were identified, but results did not support the existence of a single common dimension of mathematics anxiety as represented by the six factors. (SLD)

Suggests that no matter how much algebraic thinking is introduced in the early grades, and no matter how worthwhile this might be, the failure rate in algebra will continue unless the teaching of fractions and decimals is radically revamped. The proper study of fractions provides a ramp that leads students gently from whole number arithmetic up to…

Reacts to an article published in a previous issue of this journal on the effects of graphing calculators and computer algebra systems (CAS) on students' manual calculation and algebraic manipulation skills. Considers the contribution made by Jean-Baptiste Lagrange to thinking about the role of CAS in teaching algebra. (ASK)

Investigates ways in which students use signs and endow them with meaning in their very first encounter with the algebraic generalization of patterns. Provides accounts of students' emergent algebraic thinking. Uses ethnographic qualitative methodology supported by historic epistemological research. Focuses on a discussion held by a small group of…

Discusses how to define and teach algebra given the available technology, highlighting computer algebra systems (CAS), which feature multiply-linked graphical, numerical, and symbolic manipulation utilities. The article describes: today's versus yesterday's algebra; mathematics curriculum and the CAS; and use of CAS in the classroom, which can…

Presents worksheets for students to practice substituting whole numbers into fairly simple symbolic expressions. (MKR)

Describes a pilot study on the use of computer algebra at the upper secondary level. A symbolic calculator was introduced in a pre-examination class studying for advanced pre-university mathematics. Focuses on the identification of obstacles that students encounter while using computer algebra with the theoretical framework of Realistic…

Links the use of Computer Algebra Systems (CAS) to an existing classification scheme for mathematical tasks called the MATH Taxonomy. Illustrates through concrete examples how the goals of teaching and learning mathematics can be set using this classification together with the CAS. (Author/MM)

In many countries, the traditional processes of algebra have received criticism from educational reformers. Current reform policies, national frameworks, and local implementing statements have encouraged an algebra-for-all curriculum for students. After years of effort to improve the teaching of algebra, studies indicate that students usually do…

Takes the concept of using a geometrical or visual approach to teach algebraic concepts and extends it to connect with the section on binomial expansion by using three dimensional objects. (ASK)

Investigates secondary mathematics teachers' concept definitions, mathematical understanding, and pedagogical content knowledge of slope. Indicates that geometric ratios dominated teachers' concept definitions of slope, and teachers' descriptions of classroom instruction included physical situations more often than functional situations. (Contains…

Describes the use of an application for TI-83 and TI-92 calculators called the Symbolic Math Guide (SMG) for teaching and learning the laws of exponents in algebra. Discusses ways in which the SMG can be used for teaching, review, and testing. (MM)
