Effects of Manipulative Instruction on Solving Area and Perimeter Problems by Students with Learning Disabilities

Abstract. A multiple baseline design was employed to test the effect of manipulative instruction on the perimeter and area problem‐solving performance of middle and high school students who had been diagnosed with LD in the area of mathematics. Modeling, prompting/guided practice, and independent practice in conjunction with manipulative training were employed to teach both perimeter and area problem‐solving skills. Analysis of data revealed that the students rapidly acquired the problem‐solving‐skills, maintained these skills over a two‐month period, and transferred these skills to a paper and pencil problem‐solving format. This research extends previous findings by revealing that use of concrete manipulatives promotes the long‐term maintenance of skills.     

Non-finite loss and challenges to communication between parents and professionals

Elizabeth Bruce PhD, a psychologist in private practice, and Cynthia Schultz PhD, honorary associate at LaTrobe University, both live and work in Australia. Their work on supporting parents who have children with special needs, however, has been published around the world. In this article Bruce and Schultz explore the notion of 'non-finite loss', defined as the ongoing sense of grief experienced by parents caring for children with severe disabilities. The authors discuss the issues that professionals need to consider when working with parents in these circumstances. The article closes with a set of recommendations for promoting more effective partnerships between parents and professionals.     

Mathematics-related anxiety and attitudes: examining the impact among Latina preservice teachers

The purpose of this study was to investigate mathematics-related anxiety and attitudes among Latina preservice teachers. Three sections from the Inventory of Mathematics Attitudes, Experience, and Self Awareness were administered to preservice teachers enrolled in a curriculum and instruction mathematics course during the 1st semester of a 2-semester credential program. Pre- and postsurvey data were examined among female students. There were significant differences on 5 statements that suggest positive perceptions about mathematics and 5 statements that suggest negative perceptions about mathematics. We discuss strategies to reduce mathematics anxiety and address attitudes in preservice teachers.     

The relationship between school belonging,sibling aggression and bullying involvement: implications for students with and without disabilities

Bullying is grounded in the interactions between an individual and complex social–ecological systems. Therefore, bullying involvement is not just confined to the classroom or school. Recent research suggests that sibling aggression may be a predictor for peer-level aggression. These findings may be more relevant for students with disabilities because studies suggest that students with disabilities are disproportionately involved in the bullying dynamic. Therefore, this study explored the intersection between sibling aggression and school belonging on bullying, victimisation and fighting for 14,508 students, including 1183 students with disabilities and 13,325 students without disabilities in grades 6 through 12. As hypothesised, students with disabilities reported higher levels of victimisation, bullying and fighting. Additionally, high levels of school belonging partially buffered fighting and bullying behaviours for students with and without disabilities. These findings demonstrate the importance of establishing an inclusive and safe environment for school-aged youth.     

Concentric collaboration: a model of leadership development for healthcare organizations

Drawing on their experience in a Midwest healthcare system, the authors propose a model of leadership development through action learning that embraces ‘concentric collaboration’ at its core. The present study suggests that the process of concentric collaboration can serve to strengthen the skills of the individual leader as well as foster collective leadership. Central to the model is the growth and development of the individual leader which extends outward to create connections with others, ultimately increasing the social capital necessary to effect organizational change. This work contributes to the leadership development literature by offering a comprehensive model that includes the process of individual growth as well as collective capacity, organizational factors that support or inhibit this process as well as implications for practice.     

Gender Adeptness Among Educational Administrators for Leading Innovative Initiatives in Public Education

It may be concluded that female administrators are perceived as being more adept than their male counterparts for leading innovation in schools and leveraging resources into productive outputs. It may be concluded that both genders of administrators perceive such efforts similarly. The only two skills where gender is significant are the two eornpetencies identified as being alert for new opportunities and synthesizing ideas into focused projects. For the other eight skills indicated in the survey, gender did not play a significant role in such perceptions.
