The algebraic competence of 72 12-year-old students was examined to identify profiles of understanding reflecting different algebraic knowledge states. Beginning algebraic competence (mapping abilities: word-to-symbol and vice versa, classifying and solving equations) was assessed. One week later the nature of assistance required to map algebraic symbols onto word problems was evaluated. Two weeks later unassisted algebraic problem-solving tests were completed. Cluster analyses revealed four meaningful, relatively well-ordered, arithmetic/algebraic competence profiles reflecting partial knowledge states associated with the acquisition of algebraic understanding. The findings are discussed in terms of the conceptual changes associated with the acquisition of algebraic competence.

"What is Cognitive Science?"

This lunchtime talks series is designed to introduce the University community to issues in Cognitive Science. Cognitive Science is one the the few fields where modern developments in computer science and artificial intelligence promise to shed light on classical problems in psychology and the philosophy of the mind. Ancient questions of how we see the world, understand language, and reason, and questions such as 'how a material system can know about the outside world', are being explored with the powerful new conceptual prosthetics of computer modeling.

The talks in this lunchtime lecture series are every Thursday during the Fall semester from ** 12:00-1:00 ** in the Psychology Building, Room 101 on  Busch Campus.

Note: Talks are also announced by email (with reminders sent the day of the talk) to people who have requested to be placed on our announce list. If you would like to be added to our announce list, please email the Business Office (business_manager@ruccs.rutgers.edu).
