Noticing that the " point-form " approach referred to in many recent works implies physics described on hyperplanes, an approach inspired from Dirac's one, which involves a hyperboloid surface, is presented. A few features pertinent to this new approach are emphasized. Consequences as for the calculation of form factors are discussed.

This article reports on two aspects of a professional learning (PL) and research study. Twenty-five teachers participated in two-year PL program that sought to support implement classroom connectivity technology (CCT) their Algebra I classrooms. Students one school who learned with CCT outperformed peers without CCT. Therefore, we explored the practices teacher whose students attained higher ac...

Abstract Although strong references to expertise in different theoretical approaches teacher noticing have been made the last decades, empirical knowledge about development of from novice expert level is scarce. The present study aims close this research gap by comparing three groups mathematics teachers with degrees professional teaching experience—pre-service at master’s level, early career t...
