Small remote rural schools in Quebec face an ongoing challenge to provide similar quality educational services than bigger
schools. Since 2002, the Remote Network Schools (RNS) initiative afforded schools the opportunity to reinvent their practice
by using online tools to experience collaborative learning activities with other remote schools. Teachers and students experienced
quality learning and demonstrated agency by implementing the RNS in their context. Measures include: diversity of learning
activities, quality of online classroom interactions, changes in teacher beliefs, and shifts in teacher and student roles.
Our results show that it is a viable operating method for such schools and that other schools could contemplate implementing
such innovative practices. 相似文献

Riassunto L'incubazione di lisati piastrinici con NADP provoca inattivazione della 6PGD e ne modifica la migrazione elettroforetica. Non si osserva invece attivazione della GSSG-R.

Murine type C viral information is detectable in the cellular genome of both differentiated and undifferentiated cell lines derived from 129 Mouse teratocarcinoma. Cytoplasmic RNA expression which is negligible in differentiated cells, is significantly higher in multipotential undifferentiated cells. Furthermore it was observed that in vitro differentiation of multipotent cells leads to a decrease of this expression. 相似文献

Summary The use of the method of concentration gradient of polyacrylamide gel, electrophoresis has permitted to reveal a difference in zymograms when studying the hemolymph of healthy crabs and that of crabs parasitized by the muscular microsporidaThelohania, maenadis., The zymograms of the parasitized crabs present an increase in chymotrypsin activity and variations in the zones of esterase activity.

Summary Cold acclimatization induces morphological and compositional modifications of rat epididymal adipose tissue: a decrease in fat cell size, an increase of fat cell number per g of tissue, but no significant increase in total fat cell number in the tissue; finally, an increase in protein content and a decrease in triglyceride content.Acknowledgments. We especially thank Mr M. Joliff for his very valuable help for fat cell size determination (Hospital Bichat, Paris). 相似文献
