以课堂交互软件促进大学教学质量——学习者采纳意愿及应用效果

PowerPoint用于课堂教学,已经成为大学教学中的常规活动。然而,电子演示文稿在大学课堂中的应用还存在信息单向流动、交互少等问题。基于PowerPoint的课堂互动软件提供了一种经济、方便的解决方案。教师和学习者对这种解决方案的接受度如何？Microsoft Interactive Classroom和UW Classroom Presenter两种课程交互软件在课堂教学中的试验显示：教师和学生在首次接触此类软件后均表现出较高的采纳倾向;课堂交互软件有助于学习者个性需求表达和满足,可以提高学习者的课堂参与度。但是当前已有的课堂交互类软件在功能完备性、实用性以及灵活性上尚不能有效满足教师和学生的需求。     

政治语境下的知识分子身份认同——从《多余的话》看瞿秋白的身份意识

文人和政治家这两种身份认同的激烈交锋贯穿了瞿秋白短暂的一生。从《多余的话》中可以看出,瞿秋白明显趋向于文人身份,而对政治家身份持拒斥的态度。这与他对革命的理想化认识及其绅士意识有关。瞿秋白的悲剧与其说是他个人的性格所导致的文人从政的悲剧,毋宁说是诞生在一个革命语境当中的知识分子的由于时代而造成的悲剧,甚至可以被看作是在我国现代社会急剧转型过程中知识分子命运的典型。     

Issues in Adopting a Laserdisk-Based Science Curriculum

We examined the implementation of a laser-disk based science curriculum in an elementary school. The goal was to develop a richer understanding of the principles for designing a curriculum that will adequately support teachers in adopting a learner-centered framework. Issues included: who has ownership of the classroom discussion; what types of activities are engaged in terms of the constraints imposed; and what is the teacher's response to the specific tools provided (the teacher's guide, the Circle of Learning, and concept maps). In addition to looking at the implementation pattern, we also examined the impact of the implementation on student attitudes and anxiety toward science. Results indicated little adoption of the curriculum, and teachers continued to maintain a high degree of control in the classroom. However, results also indicated significant effects of the curriculum on science attitude and anxiety. Suggestions for future research are included.     

The linguistic construction of expert identity in professor–student discussions of science

This study examines how participation in a verbal exchange during an inquiry-based classroom activity allows three college students and their science instructor to use linguistic signs (choices of words, grammatical structures, discursive structures, prosody and poetic discourse) to construct authority and expertise. Our work explores linguistic and interactional processes of identification (the dynamic construction and transaction of expert identity) and examines how discursive strategies adopted by the professor at different moments of the verbal exchange influence the students’ subsequent discursive practices and perceptions of authority. We adopt a dialogic, socio-constructivist perspective on identity, viewing personal identities as being partially constructed via interactional positioning. Our findings reveal that the attainment of expertise involves two different types of language-mediated processes: the transmission of a professional vision or intension and the emergence of a perception of agency among students. The former is centered on referential-denotative meanings of speech (elicitation of standard account and operational definition) while the latter requires effective use of pragmatic–performative functions of speech (non-evaluative and more than minimal recipient practices). Consideration is given to the need for science instructors to be able to utilize pragmatic functions of language strategically to encourage students to position themselves within the identity of science expertise.     

(Trans)lating Identity: Exploring Discursive Strategies for Navigating the Tensions of Identity Gaps

This study explored the formation and expression of gender identity among 19 self-identified transgender individuals through the use of qualitative, in-depth interviews. Through the lens of the Communication Theory of Identity (CTI), we examined how trans* individuals form and perform gender identity, the tensions produced between identity frames, and the discursive strategies used to navigate those tensions. We identified the manifestation of three specific identity gaps: personal-enacted, personal-relational, and enacted-relational. Furthermore, we discovered four discursive strategies previously recognized for navigating tensions that emerge from identity gaps: closeted enactment, passing, disengagement, and label changing, and we identified a fifth discursive strategy—hyper-engagement—used to navigate these tensions. Results revealed that these identity layers and discursive strategies collaboratively manifest and coalesce in response to specific communicative contexts. Our results are discussed within the resounding call for greater understanding of trans* identity formation and expression.     

Describing students of the African Diaspora: Understanding micro and meso level science learning as gateways to standards based discourse

In much of the educational literature, researchers make little distinction between African-American students and students of the African Diaspora who immigrated to the United States. Failing to describe these salient student differences serves to perpetuate an inaccurate view of African-American school life. In today’s large cities, students of the African Diaspora are frequently learning science in settings that are devoid of the resources and tools to fully support their success. While much of the scholarship unites these disparate groups, this article details the distinctive learning culture created when students from several groups of the African Diaspora learn biology together in a Brooklyn Suspension Center. Specifically this work explains how one student, Gabriel, functions in a biology class. A self-described black-Panamanian, Gabriel had tacitly resigned to not learning science, which then, in effect, precluded him from any further associated courses of study in science, and may have excluded him from the possibility of a science related career. This ethnography follows Gabriel’s science learning as he engaged in cogenerative dialogue with teachers to create aligned learning and teaching practices. During the 5 months of this research, Gabriel drew upon his unique lifeworld and the depth of his hybridized cultural identity to produce limited, but nonetheless important demonstrations of science. Coexistent with his involvement in cogenerative dialogue, Gabriel helped to construct many classroom practices that supported a dynamic learning environment which produced small yet concrete examples of standards based biology. This study supports further investigation by the science education community to consider ways that students’ lifeworld experiences can serve to structure and transform the urban science classroom.

The historical context of science and education at the American Museum of Natural History

In this article I critically examine the historical context of science education in a natural history museum and its relevance to using museum resources to teach science today. I begin with a discussion of the historical display of race and its relevance to my practice of using the Museum’s resources to teach science. I continue with a critical review of the history of the education department in a natural history museum to demonstrate the historical constitution of current practices of the education department. Using sociocultural constructs around identity formation and transformation, I move to the present with a case study of a teacher who transforms the structure of science education in her classroom and school as a result of her identity transformation and association with a museum-based professional education program.

身份认同:青少年文化母题及其当代表征

身份认同作为青少年文化母题的基本内容,导源于青少年时期内在的特殊矛盾。与80前青少年相比,当代青少年在认同话语、认同方式、认同策略以及认同的基本价值内核等方面都呈现出明显的符号消费的特征。这与社会财富的空前增多,公民个人生活自主权的扩大、大众文化与传媒在当代青少年生活中的全面渗透,以及独生子女政策的实施等都有很大的关系。     

文化反思与打造传统

对传统民族民间文化遗产的保护、搜集和整理是建构民族和地区认同感的重要文化手段.但是,在搜集整理的操作技术后面是怎样的逻辑和动力?文章介绍和分析了Michael Herzfeld的"文化性的私密"的分析框架,以及Nathan Light关于新疆"十二木卡姆"搜集整理的个案研究,指出在所谓的对有代表性的文化传统展示,其实是多方磋商的结果,其过程、动机和逻辑都有值得进行人类学反思的地方."文化传统保护"这一领域正是可以贯通民间文学、民俗学与人类学的中间地带.
