This paper presents the first extensive investigation of the composition of both the organic and inorganic media used by Lorenzo Lotto, one of the outstanding artists of the Italian Renaissance in the early 16th century. By investigating four paintings from The State Hermitage Museum collection (Saint-Petersburg, Russia), new insights into the artist's painting techniques were obtained, which contribute to our understanding of the transition from egg tempera to oil painting techniques that took place in Italian paintings between the 15th to the mid 16th century. Inorganic materials were determined using SEM-EDX and PLM, revealing information on the artist's palette. Of particular note was the powdered colourless glass found in the priming layer of the Madonna delle Grazie, which was most likely used as dryer. Organic materials were analysed in individual paint layers using GC-MS, and revealed a mature use of drying oils as paint binders, skilfully mixed with other organic materials and inorganic driers, to obtain the desired aesthetical and technical qualities of the paint. The study revealed that Lotto used the tempera grassa technique through most of his creative life.  相似文献

Teacher change: ideas emerging from a project for the teaching of university mathematics     

Maria Trigueros  Maria-Dolores Lozano 《Teaching in Higher Education》2013,18(7):699-710

This paper reports the changes that occurred in the didactic approaches of three professors who participated in a project intended to develop new ways of teaching mathematics to second year university students. An enactivist perspective is used to address the process of change that emerged as a result from interactions during project meetings. We describe changes in the participants' actions by looking at data obtained from the meetings and the classrooms. Teachers were able to ‘see more’ and modify their teaching practices incorporating a more open and flexible approach in accordance to their structural state which depended on their previous history. Therefore, the results varied. It was possible to observe, however, similar changes in all members of the group which included the use of vocabulary from learning theories and the inclusion of in-depth reflections on teaching and learning.  相似文献   

Developing as a teacher in the fields of science and technology     

Maria Clavert  Tua Björklund  Anne Nevgi 《Teaching in Higher Education》2013,18(6):685-696

In universities, development as a teacher may be contradicted with developing as a researcher. Most previous studies have investigated pedagogical development merely as a result of pedagogical training and ignored the dual teacher-researcher identity. This study examines what kind of meaningful experiences are perceived to have triggered and influenced the process of developing as a teacher in the fields of science and technology. The data were gathered by interviewing 10 academics who had participated in a pedagogical training offered by a Finnish technical university between 1999 and 2009. Based on a narrative analysis utilizing dimensions of transformative learning, the results highlight the influence of the working environment and experiences, and imply that teacher development process in the fields of science and technology can be better understood in terms of becoming a teacher, rather than as a continual, conscious development process. The resulting teacher-researcher identity provides a basis for pedagogical development.  相似文献

Inclusive education in Spain: how do skills,resources, and supports affect regular education teachers’ perceptions of inclusion?     

Esther Chiner  Maria Cristina Cardona 《International Journal of Inclusive Education》2013,17(5):526-541

This study examined regular education teachers’ perceptions of inclusion in elementary and secondary schools in Spain and how these perceptions may differ depending on teaching experience, skills, and the availability of resources and supports. Stratified random sampling procedures were used to draw a representative sample of 336 general education teachers (68 kindergarten, 133 elementary, and 135 secondary teachers) from the province of Alicante. The results indicated the acceptance of the principles of inclusion, although teacher skills, time, material resources, and personal supports for inclusion were deemed insufficient. Kindergarten and elementary teachers showed more positive perceptions of inclusion than secondary education teachers, and so did teachers with more personal supports and material resources than those with less supports and resources. The results are discussed in terms of its implications for practice in order to promote more inclusive classrooms in Spain.  相似文献   

Parental involvement in schooling, classroom environment and student outcomes     

Aurora Adamski  Barry J. Fraser  Maria M. Peiro 《Learning Environments Research》2013,16(3):315-328

We investigated relationships between students’ perceptions of parental involvement in schooling, their Spanish classroom environment and student outcomes (attitudes and achievement). Modified Spanish versions of the What Is Happening In this Class?, Test of Spanish-Related Attitudes-L₁, a parental involvement questionnaire and a Spanish achievement test were administered to 223 Hispanic Grade 4–6 students in South Florida. The factor structure and internal consistency reliability of the questionnaires was supported. Strong associations were found for parental involvement with students’ learning environment perceptions and student outcomes, and for Spanish classroom environment with student outcomes. When the unique and common variances in student outcomes explained by the classroom environment and the home environment were examined, the home environment was more influential than the classroom environment in terms of students’ attitudes, but the classroom environment was more influential than the home environment in terms of achievement.  相似文献   

The potential for developing educational farms: a SWOT analysis from a case study     

Maria Bonaventura Forleo  Nadia Palmieri 《The Journal of Agricultural Education and Extension》2013,19(5):431-442

ABSTRACT

Purpose: Educational farms (EFs) serve a number of social and economic functions and are part of the debate about new learning environments, multifunctional agriculture and firm diversification. Through the analysis of a case study, this paper aims to identify strengths and weaknesses, opportunities and threats (SWOT) of EFs and key factors for setting a development strategy.

Design/Methodology/Approach: A direct survey to EFs in Molise region (IT) was implemented during April-May 2017 and results were assessed following a SWOT approach.

Findings: Strong motivation and connection with agritourism activities are strengths of EFs in the region; small size, unskilled staff, lack of structured educational pathways, and limited profitability are the main weaknesses. Farms opportunities come from a territory rich in rural landscapes, environmental resources, and typical food products, and from a growing demand for educational tourism. Obstacles are in the institutional sphere and due to the absence of regional networks. Based on SWOT findings, key factors for EFs development are discussed.

Practical implications: EFs development requires innovative educational and managerial tools, a more concerted and proactive role for multiple stakeholders, and the implementation of a network approach. Study findings solicit actions from public institutions and advisory services to improve farmers’ skills.

Theoretical implications: The paper contributes to the theoretical debate about the need for a multidisciplinary approach in dealing with the analysis of EFs.

Originality/Value: The analysis underlines the importance of internal and external drivers in stimulating farms and institutions to support diversification strategies, rural development and transformation processes in inner areas.  相似文献   

Sex education and cultural values: experiences and attitudes of Latina immigrant women     

Maria Elena Villar  Maritza Concha 《Sex education》2013,13(5):545-554

The paper aims to further explore the role that culture plays in the provision and assimilation of sex education among Latina immigrants in the USA. To accomplish this, researchers conducted focus groups and interviews with 30 women from Central and South America who have lived in the USA for at least five years. Participants were asked to reflect on their experience with sex education in their home country and in the USA, and to assess how their attitudes towards sex education may impact their behavioural choices as parents and as sexually-active women. The findings demonstrate a wide range of views that did not follow patterns by common demographical proxy variables, suggesting that such variables are not enough to predict adoption of new cultural values that are different from their family's traditional norms. Instead, adherence to traditional cultural beliefs appeared to be a better predictor of attitudes and behaviours.  相似文献   

Latin American immigrant women and intergenerational sex education     

Maria Cristina Alcalde  Ana Maria Quelopana 《Sex education》2013,13(3):291-304

People of Latin American descent make up the largest and fastest-growing minority group in the USA. Rates of pregnancy, childbirth, and sexually transmitted infections among people of Latin American descent are higher than among other ethnic groups. This paper builds on research that suggests that among families of Latin American descent, mothers have a particularly strong influence on the sexual attitudes and behaviours of their children, yet that parents of Latin American descent communicate less with their children about sex than parents of other ethnic groups. It examines the messages about sex women received as children in their countries of origin, and how these messages and their views of the USA influence the sexual education women provide for their children. On the basis of data from focus groups, we suggest that, in spite of the persistence of sexual silence, some women's self-reflective analyses of their own sexual education as well as their views of the USA as a sexually more open society contribute to their views of silence as dangerous and trigger more open communication with sons and daughters. Mothers hope to break the cycle of unwanted pregnancy by speaking with daughters about the consequences of menstruation and with sons about contraception.  相似文献
