Researchers determined virtual manipulatives, on their own or as part of an instructional sequence, to be an evidence-based practice for students with intellectual and developmental disabilities (IDD; Long et al., 2022). Yet, the majority of research looking at virtual manipulative-based instructional sequences involves the phases learned in a…

Mathematics is an important but also under-explored area of education for students with disabilities, including middle school students with intellectual and other developmental disabilities. In this study, researchers taught middle school students with intellectual and developmental disabilities (IDD) to solve word problems grounded in life skills…

Mathematics instruction for students with intellectual disabilities and autism is important. However, it is imperative for researchers and practitioners to focus on the maintenance of mathematical concepts and not just acquisition for these students. Through a single-case multiple probe across participants study, researchers explored an…

Four middle school students with a developmental disability participated in a multiple probe design across students and replicated across conditions study to evaluate the effectiveness of constant time delay to teach them to create a grocery list on an iPad or iPod touch. The classroom teacher collected data on the percentage of items…

Increasingly, researchers have successfully identified strategies to promote comprehension to students who are nonreaders. Further research is needed to replicate these promising results. In the current study, we used a multiple probe across participants design to evaluate the effectiveness of an iPad app, which incorporates evidence-based…

A primary goal of instruction for students with developmental disabilities is to enhance their future quality of life by promoting skill acquisition, which will enable them to live, function, and participate in the community. One instructional method that can help students with developmental disabilities improve independence in performing daily…

Mainstream technologies are widely being employed in inclusive and special education classrooms to accommodate the learning needs of students. As the evidence of their effectiveness evolves, educators and school-based therapists need tools and documentable strategies for their implementation. This research presents an evaluation protocol to guide…

This study examined relationships between three factors related to teacher self-efficacy (use of inclusive instruction, collaboration with others, and managing disruptive behaviour) and practicing teachers' sentiments, attitudes, and concerns about inclusive education of students with developmental disabilities. We calculated Pearson…

This study assessed effectiveness of simultaneous prompting procedure in teaching two middle school students with cognitive impairment decimal subtraction using regrouping. A multiple baseline, multiple probe design replicated across subjects successfully taught two students with cognitive impairment at middle school level decimal subtraction…

The purpose of this study was to replicate previous findings indicating a moderate association between teacher perceptions of behavior as measured by direct behavior ratings (DBRs) and systematic direct observation (SDO) conducted by an external observer. In this study, data regarding student on-task and disruptive behavior were collected via SDO…

The purpose of this study was to train teachers to follow a task analysis to teach a story-based literacy lesson using adapted, grade-appropriate middle school literature to students with moderate and severe developmental disabilities. A multiple-probe-across-participants design was used to examine the effects of training teachers to follow a…

This study describes a longitudinal design (following subjects described in Rutherford & Rogers [2003, "Journal of Autism and Developmental Disorder", 33, 289-302]) to test for predictors of pretend play competence in a group of children with autism. We tested the hypothesis that developmental change in pretend play performance can be predicted by…

We are delighted to welcome you to the International Psychological Applications Conference and Trends 2014, taking place in Porto, Portugal, from 4 to 6 of April. Psychology, in our time, offers a large range of scientific fields where it can be applied. The goal of understanding individuals and groups (mental functions and behavioral…
