The articles here highlight the teacher-artist collaboration and its impact on school employees (Ansio, Seppälä, & Houni, 2017), pupils’ learning outcomes and the benefits of the arts in young peoples’ lives (Upitis, 2005) and the organisation of collaboration and reflection on results (Nevanen, Juvonen, & Ruismäki, 2012). In Denmark, the focus on collaboration and partnership between teachers and artists has developed significantly since the school reform of 2014 and the vision of “the open school” making schools responsible for organizing partnerships with the local community. The open school vision and its partnerships with the arts draws on the research by Anne Bamford about quality in arts education and how teaching in the arts improves learning skills in, for example, mathematics and reading (Bamford, 2006; Bamford & Qvortrup, 2006). This article, however, does not address the school area, pupils or teachers, but turns to artist collaboration in early childhood services. The collaboration between artists and pedagogues is, as it is in schools, a growing field, and expressed in a new law as a part of “The open day care service”. This article focuses on kindergartens, pedagogues (pædagoger, in Danish) and artists, and examines a less explored topic in the collaboration – the attention to and concrete unpacking of aesthetic processes. The aim of the article is to broaden understandings of aesthetics in early childhood services as more than art and symbolic mediated forms, but as intermediate worlds, subtle meetings, apprehension and delight in the material world that leads to something more.

Pedagogue is a distinct and widespread profession requiring a three-and-ahalf-year BA degree, leading to work in a range of settings (Jensen, 2011, p. 142). Students choose between three specialisations: early childhood services (infants), school and ‘freetime’ services (schoolchildren), and social work and special services (adults and people with special needs). Early childhood services in kindergartens accommodate children from three to six years old. The pedagogue’s approach to children is holistic and relational in a personal and professional way – a way that does not include a traditional teaching approach (Moss, 2002, p. 143). Instead, pedagogues incorporate the curriculum through a play-learning perspective by facilitating different kinds of activities and through daily routines (Ahrenkiel et al., 2013). The pedagogue is oriented towards everyday life, wellbeing and social relations (Thingstrup, Schmidt, & Andersen, 2017, p. 1) and supporting the child in becoming a democratic and independent being (Sommer, Samuelsson, & Hundeide, 2010, p. 15). However, the current restructuring of public services, including early childhood services, as a part of the educational framework, challenges the role of the pedagogue in implementing learning environments (Krejsler, 2012). In this action research examined, the pedagogues collaborated with artists and supporting the curriculum theme Cultural Expressions and Values (Sommer, Samuelsson, & Hundeide, 2010, p. 15). This theme is recently, within a new law concerning day care services, transformed into Culture, Aesthetics and Relations and thus promotes a stronger focus on aesthetics alongside the vison of “The open day care service” including partnerships with artists or art institutions. This article describes a partnership based on collaborative work between artists and pedagogues. The collaborative type of settings where children meet artists in early childhood institutions refers to partnerships based on mutual respect and a rather close collaboration which ideally takes place over an extended period of time (Borgen, 2011, p. 374). What makes this research significant, in the least in a Danish context, is the long-term collaboration, with the children meeting a new artist every six months over an 18-month period. The artists were educated at accredited Danish and foreign institutions of artistic higher education as musicians, visual artists, dramaturges, textile designers and architects. Each artist engaged with the children and pedagogues in action on three to seven occasions. After each action there followed reflections with the pedagogues, pedagogical leaders and the researcher. Theoretical Framework Drawing on insights from both philosophical (Baumgarten 1750/1992; Gross, 2002; Jørgensen, 2015; 2018) and child cultural perspectives on aesthetics (Juncker, 2017; Mouritsen, 2002; von Bonsdorff, 2009), this article is written in opposition to psychological IJEA Vol. 20 No. 1 http://www.ijea.org/v20n1/ 4 and learning approaches concerning aesthetics that express and mediate impressions, innerfeelings, and ‘the unsaid’ into symbolic forms (Austring & Sørensen, 2012, p. 93). The German Enlightenment philosopher Alexander Gottlieb Baumgarten (1714-1762) distinguished between a lower and a higher part of the cognitive faculty (Jørgensen, 2015, p. 12). Yet, he broke with the established notion of the lower cognitive faculty as a provider of concept to the higher cognitive faculty and established lower faculty cognition as an independent and sovereign source of a certain kind of cognition (Gross, 2002, p. 408). He referred to this certain kind of cognition as aesthetic cognition which he defined as sensitive, and not sensual, and as emphasizing imagination, thinking, and intuitive approaches (awareness, attunement, presentiments and sensations) (Jørgensen, 2015, p. 26; 2018, p. 25). According to Baumgarten and the Danish professor of Philosophy and History of Ideas, Dorthe Jørgensen (2015), the goal of sensitive cognition, that is aesthetics, is perfection of the sensitive: ... it is the perfection of the sensitive cognition that is the goal of aesthetics, and perfection is identical to beauty. ... Sensitive cognitions ... are specific and characterized by both unity and diversity. ... in sensitive cognitions the many individual marks of the specific are not lost in abstraction, and not only complexity is experienced, but meaning as well. In sensitive cognitions we do not only sense a multitude of marks. We also perceive a whole that is characterized both by liveliness thanks to this wealth, and by meaningfulness thanks to inner consistency. (p. 13-14) Aesthetic experience is an experience of beauty. Beauty does not relate to whether something is nice or pretty, but stresses the holistic creation of meaning and new worlds through the sensitive pathways to knowledge. One does this by creating connections to the world around one’s self (objects, persons and atmospheres) and creating, perceiving and playing with complexity, diversity and many possible options. This is described by Jørgensen (2015; 2018) as beautiful (expanded) thinking and intermediate worlds (p. 25, pp. 35-37). The intermediate world occurs in a creative act where subject and object erase and is “the sphere of our experiences of transcendence; experience of a ‘surplus’ of meaning is the content of this sphere” (Jørgensen, 2018 p. 38).

Abstract
This article contributes to the knowledge about artist-teacher collaboration by focusing on aesthetic processes in a partnership between pedagogues and artists in two Danish kindergartens over a period of 18 months. The research is within the framework of action research and links to the development project, European Children of Culture, which involved several European/Baltic/Nordic countries in 2015-2017. The article rests on empirical material (interviews, photos, video recordings and field notes from actions and reflections) and investigates how the involved adults understand, facilitate and frame aesthetic processes and how this leads the researcher to expand perspectives on aesthetics in early childhood services. The aim of the article is to rethink aesthetic processes – to explore the many layers of aesthetics, not to reduce them. Hence, aesthetic processes in kindergartens become profound aesthetic-sensitive experiences involving hands-on processes with intensified meaning, subtle meetings and intermediate worlds, and ultimately termed “beauty bubbles”.

本文通过关注丹麦两所幼儿园的教师和艺术家在18个月的合作中的审美过程,为了解艺术家与教师的合作做出了贡献。这项研究是在行动研究的框架内进行的,并与2015-2017年涉及几个欧洲/波罗的海/北欧国家的发展项目“欧洲文化之子”联系在一起。这篇文章以实证材料(采访、照片、视频记录以及行动和反思的现场笔记)为基础,调查了相关成年人如何理解、促进和构建审美过程,以及这如何引导研究人员扩展对幼儿服务中美学的看法。这篇文章的目的是重新思考美学过程——探索美学的许多层面,而不是减少它们。因此,幼儿园的审美过程成为深刻的审美敏感体验,包括具有强化意义的动手过程、微妙的会面和中间世界,最终被称为“美的泡沫”。IJEA第20卷第1期http://www.ijea.org/v20n1/2引言和焦点教师与艺术家的合作被认为在教育环境中很有价值,并发表在《国际教育与艺术杂志》上,主要与学校环境有关。这里的文章强调了教师与艺术家的合作及其对学校员工的影响(Ansio,Seppälä,&Houni,2017),学生的学习成果和艺术在年轻人生活中的好处(Upitis,2005),以及合作和反思成果的组织(Nevanen,Juvonen,&Ruismäki,2012)。在丹麦,自2014年学校改革以来,对教师和艺术家之间合作和伙伴关系的关注有了显著发展,“开放学校”的愿景使学校负责组织与当地社区的伙伴关系。开放学校的愿景及其与艺术的合作关系借鉴了Anne Bamford关于艺术教育质量的研究,以及艺术教学如何提高数学和阅读等方面的学习技能(Bamford,2006;Bamford和Qvortrup,2006年)。然而,这篇文章没有涉及学校区域、学生或教师,而是转向了幼儿服务中的艺术家合作。艺术家和教师之间的合作,就像在学校里一样,是一个不断发展的领域,并在作为“开放日托服务”一部分的新法律中得到了表达。本文关注幼儿园、教师(丹麦语:pædagoger)和艺术家,并探讨了合作中一个较少被探索的话题——对审美过程的关注和具体解读。这篇文章的目的是拓宽人们对幼儿服务中美学的理解,它不仅仅是艺术和符号中介的形式,而是作为中间世界、微妙的会面、对物质世界的理解和愉悦,从而带来更多的东西。丹麦的幼儿园(和其他斯堪的纳维亚国家一样)不是学校的一部分,其中绝大多数都是政府资助的。本文探讨了教育家和艺术家如何理解和促进美学过程,以及他们如何通过合作扩大对美学和彼此的理解。本文的理论方法是从哲学的角度看待美学,把美学作为一种敏感的认识和体验。这篇文章调查了以下问题:艺术家和教育家如何在合作伙伴关系中理解和促进审美过程,以及这如何为幼儿服务中的审美过程和体验带来新的视角?幼儿园、教师、艺术家和儿童的名字都是虚构的。1该法律于2018年7月生效。参见《Aftale I folkeetingetom Stærke Dagtilbud–alle børn skal med I fællesskabet》(丹麦议会关于强有力的日托服务的协议——每个孩子都是一个群体和社区的成员)。儿童和社会部出版(2017年,第9页)。Blomgren:Beauty Bubbles 3关于教育工作者和艺术家在丹麦,教育工作者——而不是学前教师——参与幼儿服务的教育工作。教育学家是一个独特而广泛的职业,需要三年半的学士学位,才能在各种环境中工作(Jensen,2011,第142页)。学生在三个专业之间进行选择:幼儿服务(婴儿)、学校和“空闲时间”服务(学童)以及社会工作和特殊服务(成年人和有特殊需求的人)。幼儿园的幼儿服务可容纳3至6岁的儿童。教育者对待儿童的方法是整体的,以个人和专业的方式建立关系——这种方式不包括传统的教学方法(Moss,2002,第143页)。 相反,教师通过促进不同类型的活动和日常生活,从游戏学习的角度纳入课程(Ahrenkiel等人,2013)。教育者关注日常生活、幸福感和社会关系(Thingstrup,Schmidt,&Andersen,2017,第1页),并支持孩子成为一个民主和独立的人(Sommer,Samuelsson,&Hundeide,2010,第15页)。然而,作为教育框架的一部分,目前对包括幼儿服务在内的公共服务的重组,对教师在实施学习环境中的作用提出了挑战(Krejsler,2012)。在这项行动研究中,教师与艺术家合作,支持课程主题“文化表达和价值观”(Sommer,Samuelsson,&Hundide,2010,第15页)。最近,在一项关于日托服务的新法律中,这一主题被转变为文化、美学和关系,从而在“开放式日托服务”的愿景(包括与艺术家或艺术机构的合作)的同时,促进了对美学的更大关注。这篇文章描述了艺术家和教育家之间基于合作工作的伙伴关系。儿童在幼儿机构与艺术家见面的合作型环境是指基于相互尊重和相当密切的合作的伙伴关系,理想情况下这种合作会持续很长一段时间(Borgen,2011,第374页)。至少在丹麦的背景下,这项研究的意义在于长期合作,在18个月的时间里,孩子们每六个月就会遇到一位新艺术家。艺术家们在丹麦和外国认可的艺术高等教育机构接受教育,如音乐家、视觉艺术家、戏剧制作人、纺织设计师和建筑师。每一位艺术家都会在三到七个场合与孩子们和老师们进行互动。每一次行动之后,都会有教师、教学领导者和研究人员的反思。理论框架这篇文章借鉴了哲学(Baumgarten 1750/1992;Gross,2002;Jørgensen,2015;2018)和儿童文化美学视角(Juncker,2017;Mouritsen,2002;von Bonsdorff,2009)的见解,与心理学IJEA Vol.20 Nohttp://www.ijea.org/v20n1/4以及关于美学的学习方法,将印象、内心感受和“未说的”表达和中介为象征形式(Austring&Sørensen,2012,p.93)。德国启蒙运动哲学家Alexander Gottlieb Baumgarten(1714-1762)区分了认知能力的较低部分和较高部分(Jørgensen,2015,第12页)。然而,他打破了低级认知能力作为高级认知能力的概念提供者的既定概念,并将低级认知能力确立为某种认知的独立和主权来源(Gross,2002408)。他将这种特定类型的认知称为审美认知,他将其定义为敏感而非感性的,并强调想象力、思维和直觉方法(意识、协调、呈现和感觉)(Jørgensen,2015,26;2018,25)。根据Baumgarten和丹麦哲学和思想史教授Dorthe Jørgensen(2015)的说法,敏感认知的目标,即美学,是敏感的完美:。。。审美的目标是感性认识的完美,完美与美是一致的。。。敏感的认知。。。是特定的,具有统一性和多样性的特点。。。在敏感认知中,许多特定的个体标记并没有在抽象中丢失,不仅经历了复杂性,还经历了意义。在敏感的认知中,我们不仅能感觉到大量的标记。我们还感知到一个整体,它既因这种财富而充满活力,又因内在的一致性而富有意义。(第13-14页)审美体验是对美的体验。美与事物是否美好无关,而是强调通过敏感的知识途径来整体创造意义和新世界。一个人通过围绕自己(物体、人和氛围)与世界建立联系,并创造、感知和玩复杂性、多样性和许多可能的选择来做到这一点。Jørgensen(2015;2018)将其描述为美丽(扩展)的思维和中间世界(第25页,第35-37页)。中间世界发生在主体和客体相互抹杀的创造性行为中,是“我们超越体验的领域;意义的‘过剩’体验是这个领域的内容”(Jørgensen,2018,第38页)。 哲学美学以其敏感的认知,将美学过程标记为主体和世界之间交替的创造性过程,这些过程改变了所涉及的人和环境(Jørgensen,2015)。这些过程是通过phy的实际操作过程实现的
