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.

Teachers' and At‐Risk Students' Stimulated Recall of Instruction

Abstract

Using the stimulated recall of instruction methodology, we interviewed teachers and students at risk for referral to special education about their perceptions, judgments, and decision making during the course of instruction. The results of the teacher interviews suggest that teachers respond to complex collections of student cues in their decision making about students. Teachers described themselves as more frequently monitoring the at‐risk students, although their attempts to modify instruction consisted primarily of attempts to motivate these students. The at‐risk students indicated awareness that they are experiencing difficulty in class, had somewhat less understanding of how teachers attempt to help them, and responded with anger and frustration to their learning problems.     

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.
