晚清民国时期,中国的小报繁盛。小报不论是在发行量上,还是对整个社会的影响力方面都起到了当时大报不可取代的作用,而当下小报不仅种类繁多,而且在发行、销量、社会影响方面也越发呈现出不俗的表现。在这两个阶段中,小报为什么能够在强势大报中争得自己的一席空间,原因在于小报在整个报业产业中,以其独特的发声方式,有别于主流大报的话语...  相似文献

The progressively global, neoliberal, privatised, and digital education environment poses new methodological challenges for educational researchers, prompting a need to innovate. It has been suggested, however, that better commentary and reflection on methodological innovation in education is required. This paper considers the benefits and challenges associated with the use of network ethnography, one methodological approach that has emerged to address new social complexities. We explain the rationale for, and process of, this methodology through reference to an illustrative case: a network ethnography of the outsourcing of Health and Physical Education (HPE) curricular work to external providers. In doing this we map and critique three interrelated activities (i.e. Internet searches, interviews, and network diagram construction) that constituted our network ethnography. The discussion turns to how network ethnography allowed us to access new knowledge about the outsourcing of HPE curricular work to external providers by, for example, facilitating us in asking different questions, and foregrounding various stakeholders, networks and relationships that we may not have discovered had we relied on other approaches. This illustrative case demonstrates the capacity of network ethnography to generate rich data and offers a provocation for educational researchers to consider expanding their methodological repertoire.  相似文献

Despite recent evidence that students in public schools significantly outperform their private school counterparts, private schooling continues to account for approximately 40% of secondary school enrolments in Indonesia. In an effort to explain this sustained demand, we combine analyses of PISA data with in-country interviews and school visits. Ultimately, we find that although government dependent private schools are underfunded with a high proportion of uncertified, underpaid teachers (with limited access to training and professional development), demand remains high due to their focus on religious training and education, as well as their ability to increase educational access for low-income families.  相似文献

采用文献资料、访谈、观察等研究方法,以动作学习为基点,剖析教师对游戏干预的认识。研究结果:(1)游戏干预的基本形式主要包括两大类,一是根据干预对象人数多少可分为单独干预与集体干预;二是根据教师参与方式可分为参与性干预与非参与性干预;(2)游戏干预的基本方法主要包括以教师自身为媒介的干预方法、以材料为媒介的干预方法,和以同伴为媒介的干预方法,其具体的操作手段主要有言语类和非言语类;(3)游戏干预的实施过程主要包括确定干预必要性、确定干预时机、确定干预形式、选取干预方法、设置干预情境、明确干预评价等六个基本环节。此外,还必须重视梳理学习内容与干预内容、有效地规划干预时间、明确干预目标、匹配幼儿能力、重视师幼互动节奏,以及教师培训等相关事项来保障实施过程。研究价值:基本形式的选择和实施过程是游戏干预成功的重要环节,对它们进行深入细致的研究,既能丰富游戏干预理论,又为后续的实证研究提供相应的理论基础。  相似文献

This study examines the materials of a contemporary pictorial artwork, belonging to the Macedonian Museum of Contemporary Art in Thessaloniki (Greece), and needing conservation. The combined use of micro-FTIR and micro-Raman spectroscopy allowed the identification of almost all painting materials. Moreover, the stability of a series of synthetic pigments towards accelerated ageing is investigated in applications using the contemporary binding medium styrene-acrylic copolymer. The pigments in question are: Hansa yellow PY3 and PY74, quinacridone PV19 and PR122, naphthol AS PR112, phthalocyanine green PG7 and blue PB15, dioxazine PV37, van Dyck brown PBk11, ivory black PBk9, and titanium dioxide PW6. The organic pigments were applied alone or mixed with titanium dioxide, in rutile form or as a mixture of rutile/anatase. The experimental swatches were subjected to ageing tests, and subsequently studied as to colour changes by means of colorimetric measurements, and as to the molecular structure differentiations by infrared spectroscopy in reflectance mode. The ageing tests included exposure to high temperature and humidity (90 °C, 60% RH) and to ultraviolet radiation (350 nm, 30 °C and 50% RH, with a substantial temperature increase at 90 °C for 3 days). The greater colour difference is caused by high temperature and humidity, whereas paint layers containing TiO2, and especially the mixture of the forms rutile/anatase, prove very susceptible to ultraviolet radiation, demonstrating a significant colour difference and extended molecular changes.  相似文献

The unforeseen trials of arts-based research may suppress creative and innovative explorations. Photovoice, a visual method of investigation employing participatory photography, presents a host of apprehensions. Yet, photovoice is both a valid and rich methodology that can greatly expand the reach and scope of applied communication research. In this essay, we – three applied communication researchers – discuss the complexities of photovoice, highlighting areas of consideration that interested researchers should contemplate before utilizing this methodology. Briefly exploring three of our research studies and their varying topics (i.e. long-term cancer survivors, domestic violence organizational advocacy, male body culture), we discuss three broad areas of difficulty in photovoice research: analysis, control, and exposure. Despite the unique obstacles that photovoice presents, we argue that it, along with other forms of arts-based research, are profitable and definitely worth the challenge.  相似文献
