论学生的主体地位在教学活动中的建构

中小学教学活动，关键在于充分体现教学的主体性精神。承认学生在教学中处于主体地位，即承认学生在教学中既是认识活动的主体，又是价值活动的主体。活动是学生主体地位得到落实的重要保证。学生的活动及活动方式必须得到巧妙的安排和组织。     

房地产广告文案创作与消费者接受心理

消费者接受心理是影响房地产广告文案创作水平的重要因素之一,广告设计师通常要结合目标消费群体的心理特点来进行广告文案的创作.房地产广告文案的创作与消费者接受心理之间有其特殊的内在规律.第一,别墅类房地产广告个性化趋势明显,广告与接受的相关性将更多地取决于个体因素;第二,公寓类房地产广告将进入中产化时代,消费群体的拓展将带来广告的规模效应,这恰恰与别墅类广告趋势相反,广告与消费者接受心理的相关性将更可测,更多地取决于群体因素.房地产广告的文案创作恰恰就是需要科学分析消费者接受心理,把握房地产广告之诉求趋势,以资提升房地产广告文案实施的目标性和有效性.

敦煌写卷《毛诗》P.2529号异文例释

敦煌唐写本P.2529号卷子系现存敦煌写本《诗经》中篇幅最长者,并被认为是＂依六朝善本＂抄成。从文字学的角度予以考释,发现其中的＂古文＂、＂籀文＂,不仅有利于对《毛诗》原文意义的理解,而且对研究汉字的古音、古义和最初的形义关系都有重要的实证意义。本字、源字、正字为准确理解诗句意义,厘清学界争议提供了有力的证据。此外,其中的通假字和简体字,对于研究古音通假和汉字形体的发展演变也具有重要意义。

Exergames ‘as a teacher’ of movement education: exploring knowing in moving when playing dance games in physical education

Background: A fundamental dimension of school physical education (PE) is arguably movement and movement activities. However, there is a lack of discussion in the context of PE regarding what can be called the capability to move in terms of coordinative abilities, body consciousness and educing bodily senses.

Purpose: This article explores and articulates what there is to know, from the mover's perspective, when knowing how to move in specific ways when playing exergames (dance games). Taking different ways of moving as expressing different ways of knowing as a point of departure, the following questions are the focus of this article: (i) How do students move when imitating movements in a dance game, and what different ways of knowing the movements can be described in the student group? (ii) What aspects of the movements are discerned simultaneously through the different ways of knowing the movements? (iii) What aspects seem critical for the students to discern and experience in order to know the movements in as complex a way as possible?

Design and analysis: The theoretical point of departure concerns an epistemological perspective on the capability to move as knowing how with no distinction between physical and mental skills, and also knowing as experiencing aspects of something to know. The data in this study comprise video recordings of students playing Nintendo Wii dance games in PE lessons in a compulsory school (for children aged between 7 and 16 years) in a small Swedish town. There were three PE lessons with four different stations, of which one was Nintendo Wii dance games (Just Dance 1 and 2). In total, the videoed material covers three 60-minute PE lessons, recorded during the autumn of 2012 and in which just over twenty students participated. In the study, we have used video observation as a data collection method. Jordan and Henderson maintain that video observation removes the gap between ‘what people say they do and what they, in fact, do’ (51). To conduct a systematic and thorough analysis of how the students experienced the avatar's movements, we looked for moments where all the students and the avatar could be simultaneously observed. Two video sequences were chosen, showing four students imitating two distinct and defined movements which constituted the basis for a phenomenographic analysis.

Conclusion: The result of the phenomenographic analysis shows different ways of knowing the movements as well as what aspects are discerned and experienced simultaneously by the students. In other words, these aspects also describe knowing in terms of discerning, discriminating and differentiating aspects of ways of moving. By examining a certain exergame's role ‘as a teacher,' we have emphasized the capability to move, from the mover's perspective, as an intrinsic educational goal of PE while highlighting the need for systematically planning movement education.
