[Cp(*)RhCl(PTA)(2)]X (PTA = 7-phospha-1,3,5-triazaadamantane) undergoes an H/D exchange process between the methyl groups of Cp(*) and D(2)O whose rate depends on the coordinating ability of the counterion X(-). Kinetic studies and DFT calculations indicate that deuteration involves the abstraction of a Me-Cp(*) proton by a coordinated OH(-); the formation of the latter seems to be facilitated ...

Teacher still has a prominent role in shaping the generations and teacher education institutions handle the responsibility of transformation of teachers. Teachers must have a thorough basis of the content and pedagogic practices for processing the knowledge to the level of students. This paper explores more effective ways of imparting content knowledge among elementary student teachers by compa...

Distance learning is different from regular learning in the classroom. One of the main factors which influence the effectiveness of the learning process is the interaction that exists between the teacher and the student. Our research indicates that different interactions have different effects. There are two methods used for implementing distance learning systems, i.e. synchronous and asynchron...

Large-scale educational assessment has been established as source of descriptive, evaluative and interpretative information that influence educational policies worldwide throughout the last third of the twentieth century. In the 1990s the Brazilian Ministry of Education developed the National Basic Education Assessment System (SAEB) that regularly measures management, resource and contextual sc...

INTRODUCTION Schools are a key venue for childhood obesity prevention policies. The objective of this study was to examine factors associated with elementary school teacher awareness and implementation of their schools' food and physical activity policies.. METHODS We collected data through an online survey of teachers at Utah elementary schools with food and physical activity policies. We us...

This paper uses a nationally representative school and teacher survey from Indonesia to jointly investigate the determinants of a teacher’s satisfaction level and its impacts on performance. First, we establish some stylized facts about satisfaction, showing that satisfaction with salary is systematically lower (and different) than satisfaction with other aspects of job performance. Second, we ...

The study investigates the influence of teacher competence on third grade students' reading achievement in public and independent schools in Sweden. The data derive from the Swedish participation in PIRLS 2001. Regression analysis was employed to explore the relative effects of several indicators of teacher quality. Teachers' sex, teaching experience, in-service training and co-operation with c...

While most supervised machine learning models assume that training examples are sampled at random or adversarially, this article is concerned with models of learning from a cooperative teacher that selects “helpful” training examples. The number of training examples a learner needs for identifying a concept in a given class C of possible target concepts (sample complexity of C) is lower in mode...

We consider the politics of structural choice to examine how American states govern the teaching profession. Since the 1970s, nearly all states have adopted professional standards boards to regulate the licensing and certification of public school teachers. These boards vary in their composition, powers, and relationship to other government institutions. Some boards possess much autonomy and au...

Background: A physically active or inactive lifestyle begins with intuitive interest at a very young age. This study examined the impact of selected personal, school, and home variables on young children’s intuitive interests in physical and sedentary activities. Methods: National data from the Early Childhood Longitudinal Study (US Department of Education) were examined using Cohen’s d, hierar...
