The Importance of Art Viewing Experiences in Early Childhood Visual Arts: The Exploration of a Master Art Teacher’s Strategies for Meaningful Early Arts Experiences

The visual arts can be an important and rich domain of learning for young children. In PreK education, The Task Force on Children’s Learning and the Arts: Birth to Age Eight (Young children and the arts: Making creative connections, Washington, DC: Arts Education Partnership, 1998) recommends that art experiences for young children include activities designed to introduce children to works of art that are high quality and developmentally appropriate in both content and presentation. This paper documents the teaching strategies utilized by a master art teacher at the Denver Art Museum to engage preschool-age students in art viewing experiences which were part of a museum-based art program. This research provides support for integrating rich, meaningful art viewing experiences as a regular part of young children’s arts experiences while offering early childhood educators teaching strategies for early art viewing experiences.

Construction of common interpretive spaces through intertextual loops - How teachers interpret multimodal learning materials

This study draws on several theoretical domains: intertextuality, multimodality, and the pedagogy of multiliteracies. We introduced multimodal textbook materials to eleven experienced teachers and examined, through in-depth interviews, their approach to juxtapositions of literary texts and visual artwork. Our analysis revealed (a) three attitudes toward textbook juxtapositions: unconditional approval, conditional approval, and rejection; and (b) a three-phase pattern of behavior: identifying commonalities, repeatedly comparing texts, and interpreting juxtapositions as intertextual interpretive units. We suggest that enhancing teachers’ awareness of their own thought processes may promote their insight about the contribution of the weaving of visual art into literature instruction.

基于UG二次开发的罗茨转子参数化设计

罗茨转子作为相关设备的关键零件,其设计质量决定了设备的使用性能。使用UG／Open二次开发软件包中的MenuScript编写用户自定义菜单,使用UIStyler工具制作用户交互界面。并结合罗茨转子的结构特点及其设计要求,运用UG／0PEN二次开发工具和VisualC开发罗茨转子设计系统。运用该系统,设计人员能够准确、高效的完成罗茨转子的参数化设计,并且还可以验证罗茨转子在啮合状态下的干涉情况,为转子的优化设计提供了可靠的理论依据。从而,提高了罗茨转子的设计质量和效率。     

The Balaclava as Affect Generator: Free Pussy Riot Protests and Transnational Iconicity

August 17, 2012 was a “Global Day of Action” in support of Pussy Riot, a radical feminist performance group from Russia who had been incarcerated for their “Punk Prayer” at the altar of the Christ the Savior Cathedral in Moscow in February 2012. This paper reads the “Punk Prayer” as an image event with an extensive afterlife, mobilized through the transnational icon of the balaclava. By reading its production (socially and spatially) along with its circulation, evident in solidarity protest images, it argues that transnational iconicity enables transnational solidarity, an affective sense of connection and responsibility.     

Response to Reidun Tangen: insiders and relational problems

This paper reports the experiences of special education needs co‐ordinators (SENCOs) on the inclusion of pupils with a visual impairment (VI) in mainstream schools in Northern Ireland. A mixed method approach (postal questionnaire survey (n=113) and interviews (n=6)) was utilised to triangulate the findings. The results indicate an inverse relationship between school years and pupil numbers, with negligible numbers of pupils with a VI reported in higher level examination classes. They also reveal that, for health and safety reasons and due to problems in accessing text books, some schools discourage pupils with a VI from studying subjects such as technology and design, physical education and mathematics. While pupils with a VI are thought to enjoy the social aspects of school life (e.g., peer friendships), less is known about their ability to access a number of areas within the school, including lunchtime clubs and the dinner hall. These findings raise questions about the qualitative nature of the educational experience afforded pupils with a VI.     

Students' Visualization of Metallic Bonding and the Malleability of Metals

This study investigated the mental representations of metallic bonding and the malleability of metals held by three male students aged 14–15 (Year 10) who were attending a Hong Kong school. One student was selected by their chemistry teacher as representing each of the highest, the medium, and the lowest level of attainment in chemistry in a school that admitted students of average general attainment. The students were interviewed and their understandings probed through their provision of drawings and their interpretation of the diagrams that had been previously used by their teacher. Dual coding theory was used to interpret the relative significance of visual and verbal input and the interaction between the two for their understanding. There was evidence that students relied on verbal recall in providing their initial understandings and showed an appreciation of the nature of the structural components of the electron-sea model of metallic bonding. However, they varied in terms of their appreciation of the electrostatic force which was responsible for the malleability of metals. The study suggests that a clearer understanding of the electrostatic force involved can be attained when students experience visual and verbal representations simultaneously, a conclusion supported by dual coding theory. Principles for good practice in using diagrams in teaching are discussed.
