This one‐term practitioner research study, conducted with 33 Year 5 children, considers the impact of teaching exploratory talk skills on the learning of the class, with particular consideration of the development of the ability of gifted and talented children to manipulate and control sentence structure to create effect. Beginning with metatalk activities, the class defined new talk rules, putting them into practice in an action‐research project. The study then went on to consider the detailed application of these skills in a focus group of six gifted children. In order to meet with the requirements of a wider study, the impact of this focus group on the learning of the whole class was observed. While many children, both those in the focus group and the wider class, appeared to embrace exploratory talk as a route to independence of the class teacher, some children were more reluctant to engage. The article concludes with an evaluation of the impact of exploratory talk. 相似文献

Changes in erythrocyte membrane glycoproteins during, leukaemia were investigated in one hundred patients. Control group contained
normal ones. The total protein and protein bound total carbohydrates (neutral sugars) in the glycoproteins extracted from
the erythrocyte membrane showed significant reduction in total protein and protein bound total carbohydrates before radiotherapy.
However, after the radiotherapy there was further reduction in total protein by 10.41% whereas there was increase in total
carbohydrates by 9.98%. Qualitative analysis reveals that with the help of lectins one can pin point the sugars which appear
or disappear due to leukaemia. The test could be of a diagnostic value. 相似文献

Perceived competence is a key motivational determinant of physical activity behaviours in adolescents, and motivational determinants are influenced by the class environment. The purpose of this study was to investigate levels of perceived physical competence, enjoyment and effort in class, focusing on gender and class‐type differences. Participants were 546 adolescents (289 males, 257 females) who were in same‐sex or coeducational physical education classes. The Hierarchical Physical Competence Scale (HPCS) and questionnaire measures of enjoyment and effort in classes were used to investigate students’ perceptions. Results of 2 × 2 multivariate analysis of variance (MANOVA) indicated that students’ perceptions of physical competence, enjoyment and effort in classes differed according to gender and class type, but these differences must be viewed in light of strong interaction effects. That is, female students reported more positive and adaptive perceptions in same‐sex classes and were more affected by class type than were male students. 相似文献
