Algebra

The Algebra LearnLab course is described here.

The Algebra LearnLab course involves teaching high school Algebra I using the textbook and tutoring system of Carnegie Learning. The curriculum combines software-based, individualized computer lessons with collaborative, real-world problem-solving activities. Students spend about 40% of their class time using the software, and the balance of their time engaged in classroom problem-solving activities. Three Pittsburgh-area high schools are currently participating as PSLC Algebra LearnLab sites, offering a diverse student population, and additional high schools around the country are anticipated for future participation. Algebra I topics include:

• Organizing Single Variable Data
• Simplifying Linear Expressions
• Finding Linear Equations from Graphs
• Solving Linear Equations and Inequalities
• Standard Form
• Slope Intercept Form
• Mathematical Modeling
• Linear Expressions and Equations
• Quadratic Expressions and Equations
• Solving Systems of Linear Equations Algebraically and Graphically
• Solving and Graphing Equations Involving Absolute Values
• Problem Solving using Proportional Reasoning
• Analyzing Data and Making Predictions
• Powers and Exponents

Numerous studies in the algebra LearnLab course can be found in all three of the research clusters: Coordinative Learning, Interactive Communication, and Refinement and Fluency.
