Examines arithmetic and algebra knowledge from a cognitive perspective in an effort to determine what constitutes a pre-algebraic level of understanding. Presents results of a longitudinal study designed to investigate students' readiness for algebra. Proposes a model for the transition from arithmetic to pre-algebra to algebra. Contains 29…

Demonstrates a change in the goals of teaching the algebra of equation-solving in Victoria, Australia that requires a transition from a way of solving problems in arithmetic to a conceptually new algebraic way. Contains 20 references. (Author/ASK)

Approximately 1,200 students in years 7 to 10 were tested on recognizing, using, and describing rules relating 2 variables. Fourteen interviewed students saw a variety of patterns, many of which were not helpful for algebra. Outlines critical steps in moving from a table to an algebraic rule. (MKR)

Investigates whether the use of computer algebra systems could provide a significant advantage to students taking standard university entrance calculus examinations. Indicates that supercalculators would probably provide a significant advantage, particularly for lower-achieving students. Demonstrates that it is possible to write questions in which…

Focuses on the implications of key findings and theoretical positions from social and cognitive developmental psychology of the use of information technology (IT) tools to support learning in algebra. Presents evidence from a small-scale study of graphics calculators in Hong Kong that supports the feasibility of the UK Cognitive Acceleration…

Reports on an experiment in which Algebra I students (N=181) learned to translate word problems with two unknowns from the prose representation to symbolic representation using two variables when first solving word problems with two unknowns. Concludes that students who had learned to solve equations with the new method scored higher than those…

Reports on how students managed some technical aspects of graphics calculators as they used them to study graphs of straight lines and parabolas. Identifies three common student difficulties: (1) tendency to be unduly influenced by the jagged appearance of graphs; (2) poor understanding of the zoom operation; and (3) limited grasp of the processes…

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…

Investigates how different problem presentations promote the construction of different cognitive models in school students (N=268) aged 14 to 16. Concludes that the lack of correspondence between a cognitive model of the situation and an algebraic representation of relationships in a problem is a powerful obstacle to the use of algebraic methods.…

Examined differences in connectedness of instruction on equivalent algebraic expressions between an expert and two novice teachers by analyzing lesson plans, observations, and postlesson interviews. Only the expert teacher used both lesson and content connectedness to guide teaching. Differences in teachers' views and uses of connectedness are…

University students (n=158) were examined to determine whether first describing a mathematical relationship by a written English sentence would affect success in constructing an algebraic equation. Students using common idiomatic forms of English that could not be directly translated into mathematical notation were found to be the most successful.…
