An evaluation of daylight distribution as an initial preventive conservation measure at two Smithsonian Institution Museums, Washington DC, USA

This paper presents the results of a light levels survey conducted at the Donald W. Reynolds Center for American Art and Portraiture in Washington DC. The museum space is shared by the National Portrait Gallery and the Smithsonian American Art Museum. After six years of extensive renovations, the building reopened to the public in July 1, 2006. The structure was not originally designed to house a museum collection since it contains numerous openings such as windows, doors and skylights, which provide a path for natural radiation to enter the building and come in contact with the artworks. From a preventive conservation standpoint, this is an important problem since sensitive works of art in the collection may be subjected to damage caused by light exposure. Environmental data loggers installed throughout the museum were programmed to take successive measurements every 10 min for 24 h a day, 7 days a week and 52 weeks a year. This light levels assessment started in November 1, 2007 and finished in October 31, 2008. This study presents a new method for determining natural radiation exposures registered in exhibition spaces that rely on both electric lighting and natural lighting, considering the growing trend of using daylight illumination in museums.     

Education the Foundation for Freedom and National Strength

One of the most pressing problems facing the nation today is the need to improve and enlarge our higher education system. Many of our college facilities and faculties are already overburdened, yet the number of students seeking higher education will double in the next decade. This paper points out the steps that must be taken to increase the number of potential teachers and to induce sufficient numbers of them to choose teaching as a career. A greater effort must also be made to see that more of our most able high school graduates have an opportunity to pursue a higher education; at present, one third of the top quarter of our high school graduates do not go on to college. A recent study of Russian education made by the U. S. Office of Education is reported and the relative emphasis which Russia and America are placing on education is discussed. The cost of meeting the increased educational needs in America will be immense by current standards, but the cost of not meeting these needs will be far greater.     

Conceptualising and testing the relationship between actual and perceived motor performance: A cross-cultural comparison in children from Australia and Germany

ABSTRACT

Previous studies investigating the relationship between motor skill, physical activity and fitness in children have not thoroughly considered the role of self-perception. Therefore, the study aim was to test a theoretical framework, which considered both actual and perceived motor skill as well as actual and perceived fitness. Potential moderating effects of sex and country were considered. Data on motor skill, fitness, as well as self-perception of motor skill and fitness were collected from 145 Australian children and 214 German children (age range 7 to 10 years). For actual motor skill and fitness, mean differences for sex, age and country were found. For perceived motor performance (perceived motor skill and perceived fitness) no mean differences were found for age. Path analyses were performed. The final model showed significant relations between actual performance (object control skill, fitness) and perceived performance (object control skill, fitness). All model paths had low to moderate regression weights with the lowest relationship reported between actual and perceived fitness. Sex and country showed no effects. This integrated approach has led to a better understanding of the relationship between children’s perceived and objective performance, and cultural differences within them.     

Students’ confidence in their performance judgements: a comparison of different response scales

We report results of two studies on metacognitive accuracy with undergraduate education students. Participating students were asked to judge their personal performance in a multiple-choice exam as well as to state their confidence in their performance judgement (second-order judgement [SOJ]). In each study, we compared four conditions that differed in the type of the presented 5-point confidence scale for SOJs. In Study 1, four bipolar scales with different labels were applied; in Study 2, unipolar and bipolar scales were implemented. The results of Study 1 with N?=?420 students show that undergraduates on average provided accurate performance estimations. However, students were not aware of their judgement accuracy, shown by a low fit of SOJ and judgement accuracy. In addition, the type of provided scale significantly influenced the SOJs. Study 2 with N?=?348 students replicated the findings of the first study and gave further insight into the effects of uni- vs. bipolar response scales.     

Written artefacts in post-conference feedback sessions: the running commentary as a support for teacher learning

Written artefacts often form a significant part of teacher education activities and play a crucial role in the dialogue between tutor and student teacher in a post-observation feedback session. However, although the dialogue of feedback sessions has been extensively researched, the role of the artefact has been less explored. This research examines how the written artefact of a running commentary guides or constrains the pedagogical conversation between tutor and student teachers, as well as how it represents the power and authority of the tutor and the teacher education establishment. The article concludes with implications for pre-service teacher education practice.
