Research on dyscalculia has focused almost exclusively on elementary-aged students' deficits in speed and accuracy in arithmetic calculation. This case study expands our understanding of dyscalculia by documenting how one college student with dyscalculia understood algebra during a one-on-one design experiment. A detailed case study of 19 video…

Students with learning disabilities/difficulties in mathematics often apply ineffective procedures to solve word problems. Given that current mathematics curriculum standards emphasize conceptual understanding in problem solving as well as higher-order thinking and reasoning, the purpose of this study was to evaluate the impact of a model-based…

This research synthesizes studies that used a Digitalized Interactive Component (DIC) to assess K-12 student mathematics performance during Computer-based-Assessments (CBAs) in mathematics. A systematic search identified ten studies that categorized existing DICs according to the tools that provided language assistance to students and tools that…

In this case study, we examine the usage of language -- how teachers used and regulated their language when teaching English language learners (ELLs) with learning disabilities (LD) how to solve mathematics multiplication problems. We focus on types of scaffolds used by teachers to identify how scaffolding helps ELLs with LD build better…

Students with autism spectrum disorders (ASD) are being included more frequently in general educational settings, and are therefore increasingly expected to access and master core curricular content, including mathematics. This comprehensive literature review synthesized eleven studies of mathematics intervention strategies for students with ASD.…

This paper introduces a revised model for the development of basic computation skills. The model draws on four key phases, which have proven to be important for the development of calculation strategies and stresses the use of gestures and the verbalisation of concrete and mental images. This seems to be of crucial importance for children with…

Reform-based math instruction calls for students' construction of conceptual understanding, solving challenging problems and explanation of reasoning. However, existing literature shows that students with learning disabilities (LD) easily get lost in reform-based instruction. As an outcome of collaborative work between math education and special…

As a pedagogical approach, problem-based learning (PBL) has shown success for average and gifted students (HmeloSiver, 2004) and there are numerous incentives for its implementation in online learning environments (Savid-Baden, 2007; Chernobilsky, Nagarajan, & Hmelo-Silver, 2005). However, little research has been conducted regarding the…

This study addressed the problem of why students with learning disabilities in mathematics too often fail to develop multiplicative and divisional concepts/operations. We conducted a constructivist teaching experiment with 12 students (nine 5th and three 4th graders). This report focuses on three students' conceptual progress, particularly on…

The study compared 86 learning disabled (LD) with 86 matched non-learning disabled (NLD) children (7-11 years old) on three domains of variables: social problem solving skills, school behavior, and family background. The LD children were deficient in all three domains. More specifically, they were able to generate fewer alternatives for solving…

The study investigated the impact of participation in a creativity instructional program on measures of creative thinking and problem solving with 49 learning disabled intermediate level students and a control group of 24 nondisabled students. The Purdue Creative Training Program was used as the independent variable. Analysis of verbal fluency,…

The experiment reported here investigated how verbalization of subtraction with regrouping operations influenced learning disabled students' self-efficacy and skillful performance, and also explored how effort attributional feedback affected these achievement behaviors. Learning disabled students (N=90) from grades 6 through 8 received training…

Cognitive social skills were assessed in 22 learning disabled (LD), 18 behavior problem, and 20 control boys in grades 7-9. Measures included an interview tapping social knowledge, self-reported behavior, generation of alternative solutions to social problems, and the Wechsler Intelligence Scale for Children-Revised Vocabulary Scale. Sociometric…

In this study, children (ages 7-12) of average intelligence who had learning disabilities (LD) (n=29) and typical children (n=30) were individually tested in a task that investigated the development of proportional structures of thought. In addition, mathematical knowledge was assessed on the Woodcock-Johnson Tests of Achievement-Revised (WJTA-R).…

Youth with learning disabilities have high rates of unemployment and underemployment. A specific aspect of the poor social skills of adolescents with learning disabilities is their inability to solve unstructured problems on the job. The PROBE module was designed to help youth with learning disabilities to overcome this problem. PROBE is one of…
