Improving the reading skills of children with neurodevelopmental disabilities: Preliminary study from Botswana

In Botswana, Special Needs Education has been implemented for 25 years with some success but there is still a need for evidence-based methods like Frequency Building, behavioural fluency, and Precision Teaching to be used to measure and improve school performance and learning. We explored the impact of these behavioural technologies on reading performances of four children with learning disorders (ADHD, speech impairment and acquired brain disorder) in a special school in Gaborone. At the assessment, two children were unable to read letter sounds and two could not read sight words. Reading performances were measured with frequency and displayed on a standard celeration chart. During the intervention, the length of the tasks was reduced and then augmented. Findings revealed that after 3 months of intervention children significantly increased their score stimulating self-confidence and enthusiasm during activities. This work demonstrates that behavioural technologies can be applied in Africa without using expensive or time-consuming resources.

Three Alternatives for Graphing Behavioral Data: A Comparison of Usability and Acceptability

Making treatment decisions based upon graphed data is important in helping professions. A small amount of research has compared usability between equal-interval and semi-log graphs, but no prior studies have compared different types of semi-log graphs. Using a randomized, cross-over, experimental design with 72 participants, this study examined the relative usability and acceptability of three types of graphs: Regular (equal-interval), Standard Celeration Chart (SCC; semi-log), and Standard Behavior Graph (SBG; semi-log). All participants used each graph across three usability tasks (Plotting Data, Writing Values, and Interpreting Trends). For the Plotting and Writing tasks, the equal-interval graph produced the greatest rate of correct responses. However, for the Interpreting task the SBG produced the greatest rate of corrects, while the equal-interval graph produced the smallest rate. User acceptability mainly favored the equal-interval and SBG graphs. Study findings and implications are discussed with respect to graph usability and acceptability during day-to-day practice.
