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.     

A multiage-grouping success story

How children organize themselves in play reflects groupings found in society. Multiage grouping in schools reflects the same. Multiage grouping is grouping children of multiple ages, at least one year apart, for instruction. With renewed interest in this practice comes anxiety for teachers who contemplate such a change. Some questions teachers often ask include: How do I get started?, and How do I organize the day? This article is the success story of one teacher as she began her multiaged classroom. Perhaps her story can answer some questions and serve as a beginning model for others.     

The dynamics of online learning at the workplace: Peer-facilitated social learning and the application in practice

Research stresses the importance of social components in learning. The social contact with peers and tutors stimulates reflection and supports higher processes of learning necessary for the internalisation and application of new knowledge. However, merely proposing opportunities for interaction does not necessarily lead to fruitful discussion and collaboration. Social presence and facilitation are key concepts for successful mutual learning. Both are represented in Murphy’s collaboration model; social presence forms the basis of collaboration on which discussions and co-construction of knowledge evolve. Facilitation supports the entire collaboration process. In this paper, an adjusted version of Murphy’s model was applied to analyse 1085 comments shared in an online course between career practitioners of a public employment service. The results show that without a dedicated tutor, learners can still be involved in collaborative learning and co-construction of new knowledge provided that the topic under discussion is highly relevant and controversial. Learners themselves take over social presence and facilitation activities, but less frequently than when a professional tutor facilitates discussions. Ex post summative evaluation revealed that only a few learners applied the gained knowledge in the long-term. As comparisons with related research suggest, higher facilitation support leading to a higher cognitive interaction with the learning could have better supported the transfer to practice.     

Changing Patterns in the Middle Management of Higher Education Institutions: The Case of Portugal

Abstact Much of the writing on higher education in recent years has tended to assume that the new management push in higher education is both universal and irreversible. This paper, however, presents evidence from Portugal to challenge that assumption. While elements of the new managerialism are clearly evident in the perceptions and attitudes of academics in charge of the basic academic units (departments/schools and faculties) in the country’s universities and polytechnics, academic management remains faced with a complex, contradictory and conflicting set of demands and expectations which is likely to take a considerable time to resolve.     

What counts as knowing: Constructing a communicative repertoire for student demonstration of knowledge in science

The purpose of this study was twofold. One purpose was to identify the locally negotiated literate practices that defined ways of communicating information and knowledge across the curriculum in a fourth/fifth grade classroom. Through an ethnographic and sociolinguistic set of analyses, this investigation illustrated how the teacher worked to construct a learning environment that valued the use of multiple discourses as a way of communicating competence as a learner. Another purpose was specifically to address the ways that these practices contributed to student demonstration of knowledge in science. This was accomplished by an analysis of one student's presentation of science knowledge after a study of simple machines. A comparative analysis between his use of two discourses, written and oral, showed that the opportunity to choose between multiple discourses led to his success in demonstrating competence in ways that may have otherwise remained questionable. © 2004 Wiley Periodicals, Inc.

Teacher Knowledge and the Disjunction between School Curricula and Teacher Education

As partners in school curriculum reform, teacher educators have a responsibility to graduate students who are ready to take positions as competent and confident curriculum leaders. However, some curriculum initiatives such as those associated with the introduction of key learning areas in Australia have highlighted the disjunctions between teacher education programmes and contemporary curriculum documents. This article will explore the disjunctions from two perspectives: firstly, by examining the organisation of knowledge in schools and universities, and secondly, by presenting data from a school-based evaluation of the Health and Physical Education key learning area syllabus. The article conclude by raising implications for teacher education and the future organisation of knowledge.     

Children as research subjects: Guidelines for gatekeepers

The opportunity to conduct research in early childhood settings is vital to the growth and further professionalization of the early childhood field (Bowman, 1986; Goffin, 1989). Even though a unique body of research exists within early childhood education, more research in a greater diversity of settings and with a broader variety of groups of children and adults is needed.Mary Kay Helling is a doctoral candidate at Purdue University, Child Development and Family Studies Department; on leave from the faculty of South Dakota State University, Human Development, Child and Family Studies Department.

Attitudes towards sexuality information for adolescents: what parents should and should not say

The goal of this study was to investigate the attitudes of Colombians with respect to what can and what must not be said to young people of different ages and genders regarding sexuality. A convenience sample of 329 adults, aged 18–64 years, living in Bogotá participated in the study. They were presented with a set of 36 vignettes describing situations in which either a young girl or a young boy seemed to be concerned about sexuality and sexual relationships. Each scenario contained three items of information: the child’s gender, age and the parent’s decision (e.g. not to say anything regarding sexuality). Through cluster analysis, seven qualitatively different sets of attitudes were found. The five most common ones were: (i) it is never appropriate to talk about sexual matters (6%); (ii) delegate this responsibility to the school nurse (4%); (iii) provide incomplete information restricted to the biology of sexuality (11%); (iv) provide comprehensive information but with a recommendation of abstinence (28%); and (v) provide comprehensive information and a recommendation of pre-marital sexual experience (36%). Although it was expected that attitudes would vary as a function of the young person’s gender and age, such variations proved to be limited in their extent.
