The authors proposed a positive discipline, well-being and teaching effectiveness model that suggested that teachers’ positive discipline would facilitate students’ well-being and effective teaching, and students’ well-being would play a mediating role in the association between positive discipline and teaching effectiveness. The model was tested by including 255 resource room teachers (mean age = 32.71 years, SD = 7.09) and 255 matched adolescent students with learning disabilities (mean age = 14.06 years, SD = .74). Teachers responded to a scale for rating positive discipline strategies, and adolescents completed a students’ well-being questionnaire and a students’ awareness of teachers’ teaching effectiveness questionnaire. To evaluate the fit between the collected data and the proposed model, structural equation modelling was used to analyse the data. The results supported the proposed model and revealed that the link between teachers’ repertoire of positive discipline strategies and their students’ perception of teaching effectiveness was partially mediated by students’ well-being. Thus, the authors suggest that instead of eliminating individual student misbehaviours, teachers should focus more on positive classroom management, which is linked to improved outcomes for students and teachers. 相似文献

中国针茅属分类、分布和生态的初步研究 总被引:1,自引:0,他引:1
24 species and 4 varietes of genus Stipa L. of China have been studied and des-
cribed in this paper. It has been noted that these different species have various
geographical distributions, depending on the changes of climatic and edaphic factors
of their environments. Based on the study of floral morphology together with ecolo-
gical and distributional factors, the genus have been divided into 5 sections: 1. Sect.
Regelia Tzvel. 2. Sect. Leiostipa Dum. 3. Sect. Barbatae Junge 4. Sect. Stipa 5. Sect.
Smirnovia Tzvel.
It should be pointed out that the section Regelia as well as two members of sec-
tion Barbatae, S. purpurea and S. roborowskyi, belong to frigori-xerophilous ecotype,
distributing over Qinghai-Xizang Plateau above the forest line. The section Leiostipa
belongs to euxerophilous and mesoxerophilous ecotype, distributing widely in north-
west, southwest, northeast and east and extends to the forest-steppe vegetational Zone
of China. The section Smirnovia and other two members of section Barbatae, S.
breviflora and S. orientalis, belong to euxerophilous ecotype, with the latitudinal dis-
tribution as far as Nei-Mongo and the yellow soil plateau, with the altitudinal distribu-
tion as far as the desert steppe of Sinkang and Qinghai-Xizang plateau. The section
Stipa belongs to euxerophilous ecotype, only distributes to the mountain steppe of
north Xingkang and the last, section Barbatae is an artificial group having plumes overof the awn only, and its four species have already been mentioned above. 相似文献

This article presents a framework to help teachers facilitate small group discussions about stories children read. Collaborative reasoning discussions are intended to create a forum for children to listen to one another think out loud as they learn to engage in reasoned argumentation. Children use personal experiences and evidence from the stories to support their conclusions and consider each other's points of view. Excerpts from an ongoing study of 12 fourth-grade classrooms in rural, urban, and suburban settings are used to illustrate four characteristics of cognitive reasoning: (1) children's response to text; (2) children's use of text to consider multiple possibilities; (3) children's use of tools for persuading others; and (4) children's control of topic and turn-taking. 相似文献

This paper is focused on the Marangoni effect in the gas-liquid mass transfer systems. A series of experiments were conducted to observe Marangoni effect by a laser Schlieren system. Experimental investigations of the occurrence of Marangoni convection were presented. The typical polygonal patterns and even the reaching of chaotic interfacial flow were observed. The visual evidences were discussed and the characteristic time and scale of Marangoni convection were obtained approximately as 0.5 s and 1 mm according to the Schlieren images. From the perspective of hydrodynamic instability, the mechanism of the Marangoni convection was investigated. Though many external factors have influence on the interfacial instability, the local surface-tension gradient is the primary reason for the Marangoni convection. The small-scale interfacial flow increases the surface renewal rate. Consequently, due to the occurrence of the Marangoni effect, the mass transfer rate can be significantly enhanced. 相似文献
