Eric.ed.gov – Alternate Explanations for Learning Disabled, Emotionally Disturbed, and Educable Mentally Retarded Students’ Math Achievement. Research Report No. 11. Instructional Alternatives Project.

eric.ed.gov har udgivet: The study investigated alternative explanations for differences in mathematics achievement between pairs of handicapped students exhibiting comparable amounts of academic engaged time. Forty-two students in grades 2-4 from urban and suburban districts participated; 14 students were classified as learning disabled, 14 as emotionally or behaviorally disturbed, and 14 as educable mentally retarded. Explanations investigated were student demographics, cognitive functioning, home and family factors, teacher stress, student cognitions (including cognitive style), student motivation, behavior, and conditions in the learning environment. Of all factors investigated, only cognitive ability served as a consistent explanation for differences in math achievement for students matched on academic engaged time. Creating composite variables (specifically attitude modeling by significant others, stress/chaos in the child’s environment, and home-school cooperation) was not helpful in explaining math achievement… Continue Reading

Eric.ed.gov – Teachers’ Influence on the Quality of Pupils’ Written Explanations — Third-Graders Solving a Simplified Arithmagon Task during a Mathematics Lesson

eric.ed.gov har udgivet: The aim of this study is to find out whether there is a connection between teacher’s request and guidance for written explanation and third-graders’ achievements in solving a non-standard problem. Pupils’ task was to solve a simplified arithmagon and to explain their solution. The lessons of seven teachers were recorded and their actions were examined and categorized during a problem-solving lesson. Also pupils’ solutions were checked and classified. The teacher’s behavior seems to have a crucial role in the quality of pupils’ written explanations. The third-graders had difficulties in writing their reasoning for solving the problem.
