Twenty-five hooded rats were given 50 avoidance training sessions with leverpress IRTs obtained during as well as between sessions. Five qualitatively different shapes to the IRT profiles were found: single- or double-peaked shapes, positively or negatively accelerated shapes, and U-shaped distributions. Both the specific shape of the profile and the stability of that shape during a session were related to the avoidance proficiency of an individual rat. Six rats received two additional training sessions, with the final 30 min of each videotaped to obtain frequency counts of nine behavior categories. The observational data showed that avoidance-proficient rats typically incorporated the leverpress requirement into repetitive response chains. 相似文献

Good and poor readers at the junior high school level and good and poor spellers at the university level were compared on their ability to produce words in response to a semantic cue (a category name), a visual cue (three letters), and an auditory cue (a syllable rime). Kindergarten children were tested on a word-identification task and their retrieval of words in response to the semantic and auditory cues. At all ages, poor readers or spellers produced fewer words on all word-retrieval tasks than did good readers or spellers. Performance on the auditory and visual word-retrieval tasks correlated very highly with pseudoword reading and spelling ability in the two older groups; in the kindergarten children, auditory retrieval correlated with word identification. The results suggest that poor readers have not organized words in long-term memory according to rhyming families but that good readers have. We speculate that failure to retrieve rhyming words during acquisition of reading and spelling skills underlies the failure of poor readers and spellers to abstract the higher-order relationships between orthography and phonology. 相似文献

The purpose of this study is to investigate possible practical consequences of the ideological principle of inclusion. In this article, we investigate, compare and discuss how employees of Norwegian and Belarusian preschools perceive their own, and their preschools’, special needs education practices related to children with language difficulties. This study has a qualitative case design. The investigation contains 10 semistructured interviews of five employees from five preschools in each country. The analysis of the empirical material shows that the interviews primarily revolve around two topics: competence and sense of mastery and self-understanding. Among the staff of the Norwegian preschools, perceptions of a relatively low average competence, unsatisfactory guidance from external professionals and a low sense of mastery are prevalent. The informants from Belarusian preschools perceive a high and more specialised competence, available special needs education competence and a high degree of sense of mastery. Despite different situations and contexts, this study suggests that the preschool sector in both countries face the same challenge; how preschools can implement a form of inclusive educational practice, without at the same time relinquishing valuable special needs education competence. 相似文献

AbstractTeachers’ autonomy contributes to their development and retention decisions. While proficient teachers would benefit from more autonomy, developing teachers often require more structure and guidance. This article reviews the literature surrounding autonomy and proposes an argument for a Graduated Teacher Autonomy framework: a theoretical tool matching teacher proficiency to autonomy. This dynamic framework has the potential to support the needs of all teachers and could improve teacher satisfaction, retention, development, and administrator–teacher relations. 相似文献
