Project Activities
The research team planned to develop 150 word problems and a teaching script, followed by generalization strategies and a word problem assessment. For the pilot study, a multiple probe single-case design was planned across dyads, and replicated across classrooms, to evaluate the potential impact of the intervention on word problem solving as well as generalization to real-world activities and a general education context. The team planned to develop a manual with the instructional package and supporting materials upon completion of the pilot study.
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.
