Parents with a migration background are underrepresented among parent representatives at schools in Germany. However, increased involvement of these parents is essential for a lively democratic culture. To explore the motivations of parents with migration background regarding their school involvement, interviews with N?=?31 parent representatives with migration background were content analysed, starting deductively from a set of categories according to the theory of planned behaviour. In the analysis, the main category ??attitude?? was deductively subdivided into ??motivation in the course of action/intrinsic value??, ??results and consequences regarding own interests?? and ??results and consequences regarding others/altruistic motivation??. ??Subjective norm?? was inductively differentiated into ??other parents??, ??teachers and leadership team?? and ??other persons/perceived general expectations??; ??perceived behavioural control?? was differentiated into the subcategories ??assertiveness and freedom from anxiety??, ??language competence??, ??socioeconomic background??, ??availability of time??, ??setting in school and school district?? and ??field expertise and know-how??. Additionally, ??habit?? was deductively established and retained as a main category. Analysis of 513 statements resulted in an interrater-agreement of ???=?0.82. Implications for working with parents in an intercultural context are discussed. 相似文献

In this article, the potentials of advanced technologies for learning in science exhibitions are outlined. For this purpose, we conceptualize science exhibitions as dynamic information space for knowledge building which includes three pathways of knowledge communication. This article centers on the second pathway, that is, knowledge communication among visitors. We argue that advanced technologies have specific potentials to support all forms of visitor-to-visitor knowledge communication and, furthermore, allow for new forms of knowledge communication among unacquainted visitors and beyond the actual museum visit. We discuss mechanisms of collaborative learning with regard to their relevance for visitor-to-visitor knowledge communication and present prototypical advanced media applications in science exhibitions that address these mechanisms. This article both contributes to our understanding of collaborative learning in science exhibitions and the support advanced technologies can provide for visitor-to-visitor knowledge communication in science exhibitions. 相似文献

In this study, we examined the use of cognitive tools provided in a problem-based hypermedia learning environment for sixth
graders. Purposes were to understand how the built-in tools were used, and if tool use was associated with different problem-solving
stages. Results showed that tools supporting cognitive processing and sharing cognitive load played a more central role early
in the problem-solving process, whereas tools supporting cognitive activities that would be out of students' reach otherwise,
and hypothesis generation and testing were used more in the later stages of problem-solving. The findings also indicated that
students increasingly used multiple tools in the later stages of their problem-solving process. The various tools, performing
different functions, appeared to enable students to coordinate multiple cognitive skills in a seamless way and, therefore,
facilitated their information processing. Results also suggested that students with higher performance scores made more productive
use of tools than students with lower performance scores. Findings of the study, are discussed. 相似文献

The identification and localization of the proteinaceous binders are essential issues in studies of painting materials and techniques, for further proposing valid restoration and conservation treatments of the painted or polychrome works of art. The challenge for analytical chemists and conservation scientists is the availability of methods able to simultaneously identify and map the presence of the binders in the multilayered structure of a sample and the possibility to use a very low amount of sample from the studied art object (considering also the criteria of minimum sampling). These methods should be fast, reproducible in different artefacts and in case of mixture of protein-based binders with other non-proteinaceous constituents (oils, resins, waxes, gums etc.) and also economical (both in terms of materials and time consume). In this context, the present paper proposes an innovative protocol of investigation using two complementary techniques – Matrix-Assisted Laser Desorption/Ionisation – Time of Flight Mass Spectrometry (MALDI-TOF MS) and staining tests (one visible and one fluorescent stain) assisted by Optical Microscopy (OM) on cross-section of samples – for the simultaneous identification and mapping of protein – and oil-based binders in paint materials. The novelty is based on the use of MALDI-TOF MS on cross-sections of paints together with a fluorescent stain for protein identification and mapping (mainly used in the area of proteomics) complementing the use of a traditional visible stain for oil-based material identification. The protocol was successfully applied on several samples taken from a Czech medieval polychrome sculpture, entitled “The Mourning of Jesus Christ” (16th century) belonging to the Moravian Gallery (Brno). 相似文献

This article deals with a theory-based investigation of the diagnostic problem-solving process in professional contexts. To begin with, a theory of the diagnostic problem-solving process was developed drawing on findings from different professional contexts. The theory distinguishes between four sub-processes of the diagnostic problem-solving process and includes several hypotheses. According to the theory, the quality of the sub-processes “representing information” and “testing hypotheses” causally influences the diagnostic problem-solving success. Additionally, the theory suggests that the influence of “testing hypotheses” on the problem-solving success is higher than the influence of “representing information”. Moreover, the theory assumes that the influence of the quality of “representing information” on the success is mediated by the quality of “testing hypotheses”. These hypotheses were examined in the context of car mechatronics using diagnostic problems of the car sector, a computer-based assessment and a sample of car mechatronic apprentices (N = 339). To operationalize the sub-processes’ quality, observable critical behavior was theoretically identified and extracted from computer-generated log-files. The empirical results were largely in line with the hypotheses and indicated a (very) first corroboration of the theory in the context of car mechatronics. The theory could be helpful to investigate and teach diagnostic problem solving in different professional contexts. Further studies, however, should scrutinize whether the theory applies to other studies and professional contexts. 相似文献
