Children with disabilities demonstrate fewer complex pretend play behaviors than children with typical development, which might limit their social participation in early childhood settings. A multiple-probe design was used to examine the relation between a single prompt procedure--constant time delay--and the acquisition, maintenance, and…

Children who struggle in mathematics have a limited understanding of the foundational processes of mathematics. A lack of conceptual understanding causes students to fall behind as they progress through the core curriculum. Children at high risk for developing mathematics disabilities fail to gain numeracy knowledge. The purpose of this case study…

Collaboration with parents and caregivers to support young children's communication development is an important component to early intervention services. Coaching parents to implement communication support strategies is increasingly common in parent-implemented interventions, but few studies examine the process as well as the outcomes. We explored…

The objective of this paper is to discuss how blind students learn basic concepts of probability using the tactile model proposed by Vita (2012). Among the activities were part of the teaching sequence "Jefferson's Random Walk", in which students built a tree diagram (using plastic trays, foam cards, and toys), and pictograms in 3D…

Analysis and interpretation of behavior-environment relations are increasingly being conducted with data that have been derived descriptively. This paper provides an overview of the logic that underlies a sequential analytic approach to the analysis of descriptive data. Several methods for quantifying sequential relations are reviewed along with…

As part of Project BICAR (Binford Individualized Curriculum and Analysis Research), the study determined the effects of sequentially based objectives and criterion referenced tests on academic performance of 42 second, fourth, and sixth graders (eight of whom tested 1 to 4 years below grade level). A review of the literature supported the premise…

The first of five articles in this journal reports on a project aimed at studying the influence of the way in which problems of arithmetic are worded. Some variables in the wording were found to affect the performance of children, and terms were isolated which increased the percentage of failure. The second article describes a technique for…
