Responding to concerns that engineering is a poorly understood occupation and that young people are exposed to stereotyped
images of scientists and engineers at an early age, this investigation sought to identify how science and engineering is portrayed
in contemporary junior fiction (ages 8–12) and to what extent. An examination of 4,800 junior fiction titles in one region
in New South Wales, Australia, identified as few as 71 titles that addressed themes related to engineering and the sciences.
While the crazy, nerdy, scientific stereotype exists in these stories, mostly in humorous vein, we found that fictional characters
were split between the nerdy, eccentric, and the more serious and professional types who were depicted as more popular. The
emphasis was on male characters, but not exclusively so. There were limited details that could be associated with engineering.
Where building, making, and working with machines featured, they were depicted as male activity and primarily connected to
vehicles, mostly cars. We concluded that while young people, particularly girls, were unlikely to gain accurate or compelling
images about engineering as an occupation from this source at present, as a medium for informing the young and their parents,
the potential of fiction was considerable. 相似文献
First- and 3rd-year university students were surveyed regarding cultural attitudes and climate. Comfort in cross-cultural situations and respect for other cultures correlated with overall satisfaction for all students. However, the more Asian Americans, Hispanic Americans, and Whites were aware of diversity and changing their behavior accordingly, the less satisfied they were. Awareness of diversity was not related to overall satisfaction for African Americans. 相似文献
In this study, data in the form of (preservice teacher) student voices taken from mathematical autobiographies, written at the beginning of the semester, and end-of-semester reflections, were
analyzed in order to examine why preservice elementary school teachers were highly motivated in a social constructivist mathematics
course in which the teacher emphasized mastery goals. The findings suggest that students entered the course with a wide variety
of feelings about mathematics and their own mathematical ability. At the end of the semester, students wrote about aspects
of the course that “led to their growth as a mathematical thinker and as a mathematics teacher…” Student responses were coded
within themes that emerged from the data: Struggle; Construction of meaning [mathematical language; mathematical understanding];
Grouping [working in groups]; Change [self-efficacy; math self-concept]; and the Teacher’s Role. These themes are described
using student voices and within a motivation goal theory framework. The role of struggle, in relation to motivation, is discussed. 相似文献
To characterize cognitive maturation through adolescence, processing speed, voluntary response suppression, and spatial working memory were measured in 8- to 30-year-old (N = 245) healthy participants using oculomotor tasks. Development progressed with a steep initial improvement in performance followed by stabilization in adolescence. Adult-level mature performance began at approximately 15, 14, and 19 years of age for processing speed, response inhibition, and working memory, respectively. Although processes developed independently, processing speed influenced the development of working memory whereas the development of response suppression and working memory were interdependent. These results indicate that processing speed, voluntary response suppression, and working memory mature through late childhood and into adolescence. How brain maturation specific to adolescence may support cognitive maturation is discussed. 相似文献
Purpose: This study explores the use of advisory services by farm managers and its linkages with the economic, environmental and social performance of farms.
Design/methodology/approach: Using cluster analysis we determined groups of farms according to their sustainability performance and explored the correlations between contacts with advisory services and a set of farm-level sustainability indicators.
Findings: There exist significant differences in the number of farmers’ contacts with advisory services across countries, type of farms, farmers’ degree of agricultural education, utilized agricultural area, legal type of farm ownership and economic size of the farms. We identified three groups of farms that have different sustainability performance, are different in farm characteristics and relate differently to advisory services. The number of contacts with advisory services is positively related to the adoption of innovations, the number of information sources utilized and the adoption of farm risk management measures. We find no clear linear relationship between advisory services and environmental sustainability.
Theoretical implications: This study derives hypotheses to analyze causalities between indicators of farm-level sustainability and advisory services.
Practical implications: Results suggest the importance of taking into account the heterogeneity of farming systems for the design, targeting and evaluation of advisory services. In addition, results confirm the importance of selection of indicators that can be used in multiple sites.
Originality/value: We used a harmonized indicator of advisory services and a harmonized set of farm-level sustainability indicators in nine different EU countries that could be used to evaluate the role of advisory services in the achievement of multiple objectives in different groups of farms in multiple sites. 相似文献
This paper reports on the conclusions drawn from an investigation of the modern mathematics reform movement in Brazil. The focus of the study was an analysis of the mechanisms of transfer of knowledge from developed to developing countries, through a case study of Brazil and its adoption of the modern mathematics curriculum.The report presented here focuses on the dynamics of the reform movement and on the consequences of the movement for Brazilian mathematics education. The movement is studied as to how ideas about modern mathematics reform were disseminated to the Brazilian mathematics education community and the consequences due to misinterpretations of the intended curriculum in the implementation process. The intent of the study is that future initiatives in curriculum change proceed more efficiently in light of previous experiences, without repeating the mistakes committed in the past. 相似文献
A questionnaire survey of 300, 14 and 15 year-old pupils in England and Spain was carried out to investigate pupils' general
ideas about the process of buring and their ideas about specific types of combustion, using open-ended and structured response
questions. Pupils' responses were analysed and categories were defined from a classification scheme previously reported by
Andersson (1990). A possible model for progression of pupils' ideas about combustion is discussed.
Specialization: science teacher education.
