Stylet-Bearing Nematodes Associated with Plants in Iowa Prairies

Native Iowa prairies contained a plant parasitic nematode population which differed markedly in predominant species from populations in cultivated fields. Nematode species and their abundance varied among the five prairies sampled. Aorolaimus was common in most prairies, but is not known in Iowa cultivated soils. Tylenchorhynchus maximus was common in the Kalsow and Sheeder prairies, but was not found in the Cayler and Hayden prairies. Helicotylenchus was common in all prairies, but the species were unevenly distributed

Sighted and visually impaired students’ perspectives of illustrations, diagrams and drawings in school science

In this paper we report on the views of students with and without visual impairments on the use of illustrations, diagrams and drawings (IDD) in science lessons. Method Our findings are based on data gathered through a brief questionnaire completed by a convenience sample of students prior to trialling new resource material. The questionnaire sought to understand the students’ views about using IDD in science lessons. The classes involved in the study included one class from a primary school, five classes from a secondary school and one class from a school for visually impaired students. Results Approximately 20% of the participants thought that the diagrams were boring and just under half (48%) of the total sample (regardless of whether they were sighted or visually impaired) did not think diagrams were easy to use. Only 14% of the participants felt that repeated encounters with the same diagrams made the diagrams easy to understand. Unlike sighted students who can ‘flit’ across diagrams, a visually impaired student may only see or touch a small part of the diagram at a time so for them ‘fliting’ could result in loss of orientation with the diagram. Conclusions Treating sighted and visually impaired pupils equally is different to treating them identically. Sighted students incidentally learn how to interpret visual information from a young age. Students who acquire sight loss need to learn the different rules associated with reading tactile diagrams, or large print and those who are congenitally blind do not have visual memories to rely upon

Educação Física Escolar: Percepções do Aluno com Deficiência1

RESUMO: a inclusão de alunos com deficiência é prevista em lei e manter boas estruturas físicas e pedagógicas na escola é um ponto fundamental para que o acesso possa acontecer. A Educação Física faz parte desta inclusão e pode proporcionar grandes melhoras na qualidade de vida de alunos com deficiência. Este estudo teve como objetivo compreender as percepções do aluno com deficiência a respeito das aulas de Educação Física. Para isso foi realizada uma pesquisa de natureza qualitativa utilizando para coleta de dados uma entrevista semiestruturada a qual foi gravada, transcrita e posteriormente analisada. A amostra foi constituída de 20 alunos com deficiência matriculados em escolas regulares da cidade de Santos Dumont - MG. A partir das entrevistas, destacou-se a percepção do aluno com deficiência a respeito da Educação Física escolar; o entendimento deles quanto ao conceito de qualidade de vida; as melhoras proporcionadas na qualidade de vida através da Educação Física; as facilidades e as dificuldades nas aulas; e as questões concernentes à relação aluno/professor e aluno/aluno. Os resultados dessa pesquisa podem auxiliar a comunidade escolar e o professor de Educação Física a melhorarem a inclusão nas escolas regulares. Além disso, as percepções dos alunos com deficiência sobre as aulas podem ajudar o professor na busca de um ambiente melhor com aulas que atendam a todos e proporcionem uma melhor qualidade de vida
