Baltimore county schools get an edge in Algebra: cognitive tutor boosts middle school scores by a factor of three.A challenge at a handful of Title I middle schools in the Baltimore County Public School (BCPS BCPS Baltimore County Public Schools (Maryland) BCPS Board Certified Pharmacotherapy Specialist (pharmacist certificate) BCPS Broward County Public Schools (Florida) ) system three years ago was to figure out a way to help underperforming math students, says Patricia Baltzley, Director of Mathematics Pre K-12. "For three out of four of our Title I middle schools, we had final exam Noun 1. final exam - an examination administered at the end of an academic term final examination, final exam, examination, test - a set of questions or exercises evaluating skill or knowledge; "when the test was stolen the professor had to make a new set of data that showed our students weren't performing up to par," she recalls. "We had tried different approaches but, really, the algebra algebra, branch of mathematics concerned with operations on sets of numbers or other elements that are often represented by symbols. Algebra is a generalization of arithmetic and gains much of its power from dealing symbolically with elements and operations (such as scores were not improving at these schools. In fact, nothing we were doing with our curriculum was getting the scores to move until we introduced Carnegie Learning's Cognitive Tutor A cognitive tutor is an intelligent tutoring system which develops a cognitive model of a student as he or she interacts with the program, providing problems and individualized instruction based on this model. Algebra software program." "The Cognitive Tutor Algebra software program was part of a systemwide, data-based enhancement of the county's curriculum under the leadership of BCPS Superintendent Dr. Joe A. Hairston and Deputy Superintendent Deputy Superintendent, or Deputy Superintendent of Police (DSP), was a rank used by police forces of the British Empire. In some territories it was called Deputy District Superintendent of Police (DDSP). for Curriculum and Instruction Dr. Christine Johns. Using high-tech software to supplement curriculum improvements, the school system has focused on attaining across-the-board student achievement among even the most challenging pupil populations." "The result," she adds, "is that the scores of our final exams have climbed tremendously from a 26-percent pass rate to an 80-percent pass rate. It's been a godsend god·send n. Something wanted or needed that comes or happens unexpectedly. [Alteration of Middle English goddes sand, God's message : goddes, genitive of God, God to those students. We have also seen a significant improvement in the pass rate for Algebra on our state assessments. In fact, at these three schools, there was an average increase of 20% more students passing the high school assessment in Algebra in 2004 than in 2003." With the software-based program, the Baltimore County middle school students receive the benefits of a problem solving problem solving Process involved in finding a solution to a problem.

This supports better classroom interaction too, because teachers can spend more time with students who need additional intervention. "It is a very motivating program, very problem based," says Baltzley. "Its approach makes it very real and interactive for the kids. They deal with a problem that unfolds and use more and more of the algebra as they progress. This program approaches Algebra from a different viewpoint that requires more hands-on experiences and more cooperative learning cooperative learning Education theory A student-centered teaching strategy in which heterogeneous groups of students work to achieve a common academic goal–eg, completing a case study or a evaluating a QC problem. See Problem-based learning, Socratic method. ." But the Cognitive Tutor is more than Just a high-tech software program that keeps students tied to the computer screen. Each curriculum--including Algebra I, Geometry, Algebra II, Integrated Math Series and Quantitative Literacy Through Algebra--combines software-based, individualized computer lessons with collaborative, real-world problem-solving activities. Students spend only about 40 percent of their class time using the software, and the balance of their time engaged in a whole class, problem-solving mathematics curriculum. The software component allows students to work at their own pace. The system is built on cognitive models The term cognitive model can have basically two meanings. In cognitive psychology, a model is a simplified representation of reality. The essential quality of such a model is to help deciding the appropriate actions, i.e. , which represent the knowledge a student might possess about a given subject. The software assesses the prior mathematical knowledge of students on a step-by-step basis and presents curricula tailored to their individual skill levels. Significantly, the program is suited for all students, says Baltzley. At the three middle schools where the program has been implemented, all students--from academic classes to gifted-and-talented students to special education classes--are using and benefiting from the program, she says. "The computer labs are always packed after school with students working on the Cognitive Tutor," she says. One reason is that the textbook and classroom activities parallel and extend the development of concepts in the software, emphasizing written analyses and classroom presentations. Students engage in problem solving and reasoning, and communicate using multiple representations of math concepts. The textbook provides an opportunity for analysis, extended investigation, and the exploration of alternate solution paths. "We have implemented the program at two of our high schools and are considering implementing the program in other schools where it's needed, not just the Title I schools," says Baltzley. "It makes a lot of sense." For more information, contact Ingrid Ellerbe, iellerbe@carnegielearning.com |
