Description:

Purpose: Students with significant cognitive impairments often have difficulty participating in key aspects of the mathematics learning process. Many of these students have not had access to the general education curriculum. Recent education policy has encouraged instruction and assessment efforts to focus on grade-level content for all students, including students with moderate and severe intellectual disabilities. The major mathematics textbooks on educating students with severe disabilities include minimal information on teaching mathematics, aside from money and measurement. However, recent studies indicate that students with moderate and severe intellectual disabilities are capable of problem solving in mathematics.

The purpose of this project is to develop materials for teaching mathematical problem solving to students with moderate and severe intellectual disabilities by combining methods used to teach problem solving to students with high incidence disabilities and evidence-based practices for teaching mathematics to students with moderate/severe intellectual disabilities. The intervention will include scripted teacher read alouds and a standard problem format to improve accessibility for nonreaders; adapting schema-based instruction, including use of a graphic organizer; and teaching students to generalize the problem solving across problems, real life activities, and education settings. The intervention will also include a peer-tutoring component to be implemented in general education math classrooms.

Project Activities: During the first year of the project, 150 word problems and a teaching script will be developed. In the second year, the generalization strategies and a word problem assessment will be developed. The criterion word problem-solving assessment will be developed to measure students' ability to solve word problems related to addition, subtraction, and comparing sets/quantities. During the third year pilot study, a multiple probe single-case design will be used across dyads, replicated across classrooms, to evaluate the impact of the intervention on word problem solving as well as generalization to real world activities and a general education context. Upon completion of the pilot study, a manual will be developed to include all components of the instructional package and other support materials.

Products: The main product will be a fully developed word problem-solving intervention for students with moderate and severe intellectual disabilities, as well as peer-reviewed publications, and presentations.

Structured Abstract

Setting: The research takes place in elementary and middle schools in North Carolina.

Sample: This project will involve eight students with moderate/severe intellectual disabilities in grades 4–8 during the first 2 years and an additional eight students during the third year. Four special educators will be selected to implement the intervention across the 3-year time span, and four general education teachers will be selected to include the participants within their general education math classrooms to work with peer tutors during Years 2 and 3.

Intervention: The fully developed word problem-solving intervention will include four main components: interactive read aloud, mapping of the problem with objects and manipulatives, calculation of solution via task analysis, and generalizing the problem solving to other contexts. The intervention will incorporate instructional strategies shown to be effective for students with moderate and severe intellectual disabilities in mathematics. These include creating access to the text, promoting comprehension of the problem, teaching calculation skills, teaching the use of symbols, and promoting generalization. The intervention also includes a peer tutoring component to promote the use of the intervention in general education mathematics classrooms.

Research Design and Methods: The project involves an iterative development process for development and revision of the math problems, problem mapping, calculation, and generalization components of the intervention. The design for the pilot study involves a multiple probe across-dyads single-case design study. This design will be replicated across four classrooms and adhere to the criteria for single-case design developed by the What Works Clearinghouse (WWC). Each student will be the unit of analysis.

Control Condition: During the single-case design pilot study, individual students will serve as their own controls.

Key Measures: During the project, the team will develop a criterion word problem-solving test for mathematics understanding and inter-observer agreement procedures to promote reliability in the administration of this test. The team will also develop fidelity measures to assess teacher implementation of the scripted mathematics materials. As a more distal measure of math performance, the KeyMath3 Diagnostic Assessment will be used.

Data Analytic Strategy: Single-case data will be analyzed using visual analysis of the data pattern for each student on word problem-solving performance following WWC recommendations. These recommended steps include the prediction of the baseline data, identification of the within-phase pattern for the intervention phase, comparison of intervention phase to the baseline phase, and determination of at least three demonstrations of effects. In reviewing the within- and between-phase data patterns, the six variables to be considered are level, trend, variability, overlap, immediacy of effects, and consistency of data patterns across similar phases. Descriptive analyses of mean, range, and overall slope will also be provided for comparison between phases.
