This dissertation presents three studies exploring mathematics interventions for students with autism spectrum disorder (ASD) including a review of literature and two intervention studies using manipulative based interventions. Specifically, the researcher conducted a systematic review of literature exploring the current state of the literature on…

Play provides a foundation for human learning because people have an opportunity to experiment through play and learn in a safe environment. Although play is more free-form, expressive, and improvisational, serious play is more structured, rule-bound with a "serious" purpose (Deterding, Dixon, Khaled, & Nacke, 2011). Studies also…

Addition of fractions is an important foundation for students to experience success in mathematics. This mixed-methods study was conducted to measure the effectiveness of robotics as a mathematics manipulative with seventh grade students. Two groups of students were established: control and treatment. The control group received teacher-centered…

This study investigated the effectiveness of two remedial mathematics courses that aimed to (a) present topics conceptually, (b) construct adequate schemata, and (c) introduce students to the culture of mathematics. The topics covered during the two courses were word problems, equivalence, variables and expressions, equations and inequalities, and…

The purpose of this research was to identify if (1) there is a difference in student achievement between students who use the GeoLeg manipulative tool and students who use a traditional compass, protractor, and ruler on the same geometry unit; (2) there is a difference in student achievement between the genders between those who use the GeoLeg…

Researchers are increasingly aware of the role of spatial skills in preparing children for future mathematics achievement (National Mathematics Advisory Panel, 2008). In addition, sex differences have been consistently documented showing boys score higher than girls in assessments of spatial ability, particularly mental rotation (Linn &…
