| - | Mathematics is integral to all areas of daily life. However, assessments conducted at state, national, and international levels over the past 30 years indicate that U.S. students are “notably deficient” in their ability to solve mathematical problems [National Research Council, 2001]. Students with learning disabilities [LD] manifest even more severe problems [Cawley et al., 2001]. Contemporary research has identified effective conceptual model-based problem solving strategies for students to recognize word problem structures that underlie problems with various surface features and complexity levels and formulate model-based representation for solution. | + | **Mathematics** is integral to all areas of daily life.

| - | The proposed work includes cutting-edge research for **computer science techniques**. A joint statistical learning algorithm will be designed for identifying levels of **readability, word difficulty, and syntactic complexity** of available instructional materials in a unified framework. A relational learning algorithm will be designed for identifying sentences with relevant information from sentences with irrelevant information in a mathematical word problem. | + | The proposed work includes cutting-edge research for **computer science techniques**.

| - | The exploratory differentiated instructional system will be evaluated in a school district near Purdue University. We will address two questions: | + | |
| - | - Whether the exploratory differentiated instructional system enhances word problem solving performance of students with LD; and | + | |
| - | - Whether the proposed computer science techniques serve the function of providing appropriate instructional materials to facilitate differentiated instruction. | + | \\ |
