“对战”形式完成教学评测。学生按时完成任务可 以获得奖励,并用来升级角色的经验值(Experience Points,XP)——这将使其角色提高战斗水平并学 习新的技能。如果一个学生违反了课堂纪律,就会 失去生命值,甚至最终导致角色在“对战”中失败。 如果学生获得经验值点数,对相应角色及其团队都 有益处;相反,如果一个学生失去了生命值点数, 其团队的其他成员角色也会受到伤害,并且大家必 须完成各种额外任务。无论如何,学生们需要共同 努力才能使团队获得成功。一般而言,没有学生愿 意自己的不当行为损害团队利益,导致他人失败。 游戏团队中,学生还可以帮助彼此成长。例如,如 果学生的虚拟角色是一名战士,而队友因为上课迟 到面临生命值点数降低,则该学生可以通过完成额 外的学习任务来挽救队友。学生知道他们在课堂上 的行为会影响整个团队的进度、这会激励他们强化 课堂上的积极行为和团队合作,提升课堂学习效率。 Classcraft 每个月都会发布新的故事情节和场景供教 育工作者选择,帮助提升学生的课堂参与感 [19]。除 了在预制故事中添加课程任务外,Classcraft 还允许 教师自己编写课程,通过上传不同的学习任务来教 授不同的科目。根据在课堂活动中收集的数据,教 师还可以查看学生的行为并进行分析。
是以游戏软件为基础的学习,教育游戏(Educational Games)的设
计与开发是当前研究的主流方向。教育游戏模糊了学习与游戏、正式 学习与非正式学习的边界 [13];但是有别于教育游戏的软件性质(见表
1),教育游戏化是一套解决方案,服务于教育情境中的各类问题,
如激发学习者动机和兴趣、引导学习者面对学业失败、激发其学校生
研究表明,随着游戏在当代文化中的地位日益 提高,其在教育中能够扮演的角色也越来越多样化。 Classcraft 作为受到游戏启发开发的教育解决方案, 它对于学习的积极作用和游戏非常相似。

bialystok二语学习模型和外语教学四项原则

bialystok二语学习模型和外语教学四项原则贝里斯托克二语学习模型是一个四步模型,由英文学习领域的知名学
者朱莉·贝里斯托克(JuliaBialystok)所提出的。

它的四个步骤是:
1、认知活动:通过使用自己的母语与目标语言之间的关联来建立连接,以便学习者能够理解新概念。

2、语用活动:通过实践练习,熟悉使用新学习的语言,从而学习语言。

3、运用活动:学习者将已学习的新语言用于实际语言活动中。

4、独立活动:学习者作为一个独立的学习者,理解新学习的语言,
并能够在不断发展的新环境中独立使用新学习的语言。

外语教学四项原则是指:
1、经典原则:把语言学习作为跨文化沟通的一种经典语言学习技术,通过理解语言的文本和上下文,来理解其含义。

2、参与原则:学习外语时要充分利用合作学习的方式,让学生参与
社会语境中的活动,这样才能够更好地体验和学习外语。

3、可操作原则:学习外语时要开拓学习者的认知技能,让学生能够
掌握外语的听、说、读、写能力。

4、实践原则:学习者要理解外语的重要性,不断练习,参与真实的
语言场景,逐步融入新学的文化背景,一步一步逐渐增加学习的自信心。

六、课程实施与评价
课程的实施是由“计划-做(工作)-回忆” 三个环节以及其他一些活动组成。 实例展现(“种植生命树学校”典型的一日生活)
课程组织形式: 1.兴趣区(自选)活动 2.小组活动 3.集体活动
1.活动区活动是幼儿自主活动的过程。由幼儿 自己来进行计划、工作、回顾。
常设的活动区有:积木区、角色扮演区、美工区、 读写区、音乐与运动区、木工区、沙水区、玩具区、 户外活动区等。
十、启示
1.课程理念:
以皮亚杰的认知发展理论为基础的 High/Scope课程为我们提供了一种以建构主 义为基础的课程模式。它将课程建立在幼儿 兴趣的基础之上,真正从幼儿的角度出发去 进行课程开发,值得我们学习。
2.课程设计:
(1)为每一天的经验制定工作计划,努力 在成人发起的活动和幼儿发起的活动之间创造 出一种平衡。 (2)High/Scope课程提出的关键经验在进 行课程设计时避免了课程的重复或遗漏,同时 在实践层面上也具有很强的可操作性。
作出并表达自己的选择、计划和决定; 解决游戏中出现的问题; 考虑自己的需要; 用语词表达感受; 参与小组活动; 对他人的感受、兴趣和需要敏感; 与同伴、成人建立联系、进行和体验合作游 戏; 解决社会性冲突。
4.运动
原地的运动:弯腰、扭动、摆动、晃动; 发生位移的运动:跑、跳、滑、走、爬; 带器械运动;在运动中表现出创造性; 描述运动;按运动指令做动作; 感受和表达出稳定的节拍; 按节拍运动。
经过数十年的实践,HIGH/SCOPE除了帮助家长 了解自己的孩子,支持学校的工作,鼓励家长的参 与以外,他们在家长工作的观念上有了一个大的变 化。他们认识到家长是幼儿最重要的教育者,而家 庭环境、家庭的生活习惯对孩子有直接的影响。 因此HIGH/SCOPE要求老师对每个家庭的文化、习 俗、习惯、兴趣、信仰要有所了解,并根据每个家 庭文化背景的不同,在HIGH/SCOPE学校里向孩子提 供他们家庭文化的环境。

“4E+S”:认知科学的一场新革命?

“4E+S”:认知科学的一场新革命?

“4E+S”:认知科学的一场新革命?【英文标题】"4E+S"A New Revolution in the Cognitive Science?【作者简介】李建会,于小晶,北京师范大学价值与文化研究中心、哲学与社会学学院。

一、引言近年来,许多科学家和哲学家都认为,在认知科学领域发生了一场新的认知革命。

这一革命就是“4E+S”理论模型的兴起。

其中,“4E”指的是体化(embodied)认知、嵌入(embedded)认知、生成(enacted)认知和延展(extended)认知理论;“S”指的是情境(situated)认知理论。

与认知科学传统的计算表征理论不同,一批新的认知科学家和哲学家开始主张认知是体化的、嵌入的、生成的、延展的和情境的。

“4E+S”认知起初是由不同的认知科学家和哲学家独立倡导的,但随着这些模型讨论的增多,2007年在美国佛罗里达大学召开的一次认知科学会议上,“4E”第一次作为统一的主题被展开讨论。

也正是在这次会议上,美国蒂芬大学的美籍华人卢找律教授提出,应当在“4E”纲领的基础上再加上一个“S”,他认为近年来正在形成的认知革命综合起来就是“4E+S”。

①“4E+S”认知在认知科学的当代讨论中具有非常大的影响。

如20世纪末21世纪初,国外学界出版和发表了许多关于“4E”和“S”的著作和文章,其中,有影响力的著作有:瓦雷拉(F.Varela))、汤普森(E.Thompson)和罗施(E.Rosch)的《体化认知》(1991年),克拉克(A.Clark)和查尔莫斯(D.Chalmers)的《延展心灵》(1998年),拉考夫(koff)和约翰逊(M.Johnson)的《肉身中的哲学》(1999年),诺伊(A.Noe)的《知觉中的行动》(2004年),亚当斯(F.Adams)和艾泽瓦(K.Aizawa)的《认知的界限》(2008年),罗兰兹(M.Rowlands)的《心灵的新科学》(2010年),夏皮罗(L.Shapiro)的《体化认知》(2011年)等。

甲骨文总裁埃里森在耶鲁大学给毕业生所作的演讲全文甲骨文公司总裁LarryEllison(OracleCEO)在耶鲁大学YaleUniversity给毕业生所作的演讲全文,由于他句句惊人,很冷,最后被耶鲁大学保安请下讲台。

该演讲号称历史最牛之演讲,但是否classic则不得而知,美国出版的一本大学经典演讲集未将其收入其中。

2016年美国500强企业CEO薪酬排行榜第一:拉里·埃里森(LawrenceJEllison)甲骨文1.93亿耶鲁的毕业生们,我很抱歉--如果你们不喜欢这样的开场。

我想请你们为我做一件事。

请你---好好看一看周围,看一看站在你左边的同学,看一看站在你右边的同学。

请你设想这样的情况:从现在起5年之后,16年之后,或30年之后,今天站在你左边的这个人会是一个失败者;右边的这个人,同样,也是个失败者。

而你,站在中间的家伙,你以为会怎样?一样是失败者。

失败的经历。

失败的优等生。

说实话,今天我站在这里,并没有看到一千个毕业生的灿烂未来。

我没有看到一千个行业的一千名卓越领导者,我只看到了一千个失败者。

你们感到沮丧,这是可以理解的。

为什么,我,埃里森,一个退学生,竟然在美国最具声望的学府里这样厚颜地散布异端?我来告诉你原因。

因为,我,埃里森,这个行星上第二富有的人,是个退学生,而你不是。

因为比尔盖茨,这个行星上最富有的人---就目前而言---是个退学生,而你不是。

因为艾伦,这个行星上第三富有的人,也退了学,而你没有。

再来一点证据吧,因为戴尔,这个行星上第九富有的人---他的排位还在不断上升,也是个退学生。

而你,不是。

合作读报-提高英语学习水平

合作读报-提高英语学习水平

合作读报,提高英语学习水平作者:张雪琴摘要:本文基于建构主义理论、认知发展理论和会互赖理论,以及新课标的要求,简要分析了让学生阅读《二十一世纪学生英文报》(The 21st Teens)的必要性和可行性。

主要介绍了把合作学习方式运用于报刊阅读中以提高学生英语学习水平的一些方法,如,合作读报、合作讲报、课堂限时拼读活动、合作制报、合作复述、续编故事、角色表演等探究性活动、合作进行美文诵读或背诵活动、小组话题讨论或全班辩论,以及一些相应的注意事项和建议。

关键词:合作读报活动建议对于大多数国内学习者而言,外语作为一种工具,主要体现在读、写水平和能力上,特别是阅读,它既是人们获取信息的一种重要途径,也是社会文化交流的一种重重要形式。

因此,提高学生的阅读理解能力是高中英语教学的一个重要目标,阅读理解也成为了各种考试考查的重点。

新的课程标准对高中毕业生不管是英语阅读技能还是阅读量都提出了更高目标。

但仅靠教材的阅读训练显然很难达到课标要求,因此开发一种合适的阅读课程资源很有必要。

鉴于《二十一世纪学生英文报》(The 21st Teens,以下简称Teens)信息量大,多学科知识综合;报纸内容新颖,语言材料丰富鲜活;语言材料难、中、易合理分布、设置,适合不同水平层次的学生选择使用;按周使用学生可以灵活安排阅读时间,便于自主学习等优势,笔者选用它最为阅读的材料。

每周开一节报刊阅读课,旨在通过报刊阅读,在提高学生阅读兴趣的基础上,帮助学生掌握有效的阅读方法,提高学生的阅读能力。

一、学生合作读报的必要性和理论基础。

英语新课程改革的重点就是要改变英语课程过分重视语法和词汇知识的讲解与传授的倾向,强调课程从学生的学习兴趣、生活经验和认知水平出发,倡导体验、实践、参与、合作与交流的学习方式,发展学生的综合语言运用能力。

而合作学习作为当代比较流行的一种教学模式,它在激发学生的学习兴趣、提高学生的学业成绩、发展学生的良好的协作能力、促进学生的人际交往能力等方面有着不可替代的优势。

Learning Communities in Classrooms:A Reconceptualization of Educational PracticeKaterine BielaczycBoston CollegeOISE, University of TorontoAllan CollinsNorthwestern UniversityBoston CollegeFrom C. M. Reigeluth (Ed.): Instructional de sign the orie s and mode ls, Vol. II. Mahwah NJ: Lawrence Erlbaum Associates.IntroductionIn recent years in America there has developed a “learning-communities” approach to education. In a learning community the goal is to advance the collective knowledge and in that way to support the growth of individual knowledge (S cardamalia & Bereiter, 1994). The defining quality of a learning community is that there is a culture of learning, in which everyone is involved in a collective effort of understanding.There are four characteristics that such a culture must have: (1) diversity of expertise among its members, who are valued for their contributions and given support to develop, (2) a shared objective of continually advancing the collective knowledge and skills, (3) an emphasis on learning how to learn, and (4) mechanisms for sharing what is learned. If a learning community is presented with a problem, then the learning community can bring its collective knowledge to bear on the problem. It is not necessary that each member assimilate everything that the community knows, but each should know who within the community has relevant expertise to address any problem. This is a radical departure from the traditional view of schooling, with its emphasis on individual knowledge and performance, and the expectation that students will acquire the same body of knowledge at the same time.Why Learning Communities?As the world becomes more complex, students find themselves unprepared for the challenges, both personal and social. The new demands that society is placing on young people are reflected in a wide variety of reports on education, such as the U. S. Department of Labor’s S CANS report (1991) and a recent book by Murnane and Levy (1996), which address the question of what skills and knowledge will be needed for work in the twenty-first century. To summarize their findings, students need to be able to direct their own learning, work with and listen to others, and develop ways of dealing with complex issues and problems that require different kinds of expertise. These, for the most part. are not skills that are currently taught in schools.S o why should we redesign education around learning communities? There are at least three arguments as to why it would be good to do so:Social-constructivist argume nt. The "social-constructivist" view of education, characteristic of Dewey and Vygotsky, holds that the theory of individual learning, which pervades schools, is flawed. The constructivist view is that people learn best, not by assimilating what they are told, but rather by a knowledge-construction process. In order for individuals to learn how to construct knowledge, it is necessary that the process be modeled and supported in the surrounding community. This is what occurs in a learning community.Le arning-to-le arn argume nt. Frank S mith (1988) argues that children will learn to read and write if the people they admire read and write. That is, they will want to join the "literacy club" and will work hard to become members. Brown, Ellery, and Campione (1998) argue that there has been a change in the demand on schools, toward a goal of producing expert learners or "intelligent novices." This change has been brought on by (1) increasing knowledge, such that no one can absorb in school everything they will need to know in life, and by (2) the changing demands of work, where technology can carry out low-level tasks, requiring workers who can think abstractly and learn new skills. S o given that we want people who know how to learn, it follows from S mith's argument that children will learn to be learners by joining a "learning club."Multi-cultural argume nt. The world is becoming more closely integrated through the advent of new communication technologies, and societies are becoming increasingly diverse through mixing of people from different cultures. This requires people to interact and work with people from different backgrounds. To prepare people to live and work amid such cultural diversity, schooling needs to construct a learning environment that fosters students’ abilities to work and learn with other people. Each person’s contributions must be respected, and the community must synthesize diverse views. This is the type of learning environment that a learning-communities approach promotes.In summary, the learning-communities approach addresses the needs for students to deal with complex issues, figure things out for themselves, communicate and work with people from diverse backgrounds and views, and share what they learn with others. Therefore educational researchers in America have begun to experiment with different models of learning communities to determine which ways of organizing learning communities are most effective (Brown & Campione, 1994; Collins & Bielaczyc, 1997; Lampert, Rittenhouse, & Crumbaugh, 1996; Rogoff, 1994; S cardamalia & Bereiter, 1994; Wineburg & Grossman, in press).A Framework for Viewing Learning CommunitiesThe learning-communities approach raises a number of issues about the design of learning environments. We treat each issue as a dimension, along which we will contrast a learning-communities approach with the approach of teachers who emphasize the individual mind and how it develops. Classrooms have changed over the years to involve more social interaction, but classrooms organize d as learning communities still differ from most classrooms along these dimensions. These eight dimensions provide a framework we will use to examine three examples of classroom-based learning communities described in the next section.Goals of the community: In a learning-communities approach the goal is to foster a culture of learning, where both individuals and the community as a whole are learning how to learn. Further, members of the community share their individual effortstowards a deeper understanding of the subject matter under study. S tudents learn to synthesize multiple perspectives, to solve problems in a variety of ways, and to use each other's diverse knowledge and skills as resources to collaboratively solve problems and advance their understanding. The intent is for members to come to respect and value differences within the community. In contrast, most classrooms tend to foster a culture in which students are expected to acquire the same body of knowledge at the same time. Rather than an emphasis on diverse expertise and problem solving, there tends to be an emphasis on conformity and on learning particular subjects.Le arning activitie s Because the goals focus on fostering a culture of learning, the activities of learning communities must provide a means for (1) both individual development and collaborative construction of knowledge, (2) sharing knowledge and skills among members of the community, and (3) making learning processes visible and articulated. A learning-communities approach tends to use a variety of learning activities, including individual and group research; class discussions; cross-age tutoring; working together to create artifacts or presentations that make public both what is learned and ways of learning; and collaborative problem solving where students take on particular roles toward a common end.It should be noted that the learning activities described in a learning-communities approach and those found in most classrooms may share some similarities. However, because the learning activities are used toward different ends, differences arise. For instance, social learning techniques such as cooperative learning and collaborative learning (Cohen, 1985; Damon & Phelps, 1989; S lavin, 1986) can be used to support a learning community’s goals, but they can equally well support more traditional learning aimed at inculcating particular knowledge among students. Brown and Campione (1996) contrast the learning activities in most classrooms with those of learning communities in terms of two other factors: that the activities in a learning community operate as a system and their underlying objectives are articulated: There are by now many procedures available that were designed to foster thinking.These procedures are part of the teacher's tool box. But the procedures areunderstood as unrelated tools, not as systems of interdependent activities....Teachers may, for example, decide to include forms of cooperative learning, the useof long-term projects, a writer's workbench approach, etc. The problem we see isthat such an approach ignores the potential power of creating a classroom systemof activities that mutually influence and reinforce each other.... There is a purposefor every activity, and nothing exists without a purpose. All members of thecommunity -- students, teachers, parents, and researchers alike -- should be awareof this (Brown & Campione, 1996, pp. 292, 314).Te ache r role s and powe r re lationships: In a learning-communities approach, the teacher takes on roles of organizing and facilitating student-directed activities, whereas in most classrooms the teacher tends to direct the activities. The power relationships shift as students become responsible for their own learning and the learning of others. S tudents also develop ways to assess their own progress and work with others to assess thecommunity's progress. In contrast, in most classrooms the teacher is the authority, determining what is studied and assessing the quality of students' work.Ce ntrality/pe riphe rality and ide ntity: The degree to which people play a central role and are respected by other members of a community determines their sense of identity (Lave & Wenger, 1991). In a learning-communities approach the central roles are those that most directly contribute to the collective activities and knowledge of the community. However, opportunities exist for all community members to participate to whatever extent is possible and students working in peripheral roles are also valued for their contributions. Centrality and peripherality are context-dependent. Certain students may have more to contribute at a given time, so a student’s centrality can change over time. As members of a learning community take on different roles and pursue individual interests toward common goals, students develop individual expertise and identities. Because diversity is important, an atmosphere in which students respect each other’s differences needs to develop.In contrast, in most classrooms students work on the same things and are all expected to reach a base level of understanding. S tudents tend to form their identity through being measured or by measuring themselves against this base level. Centrality tends to mean those who meet and exceed this base level -- those who "get it." S chofield (1995) notes the benefits of such centrality in that teachers typically spend most of their time interacting with the better students. S tudents on the periphery are then those students needing remediation and extra help -- those that "aren't quite there yet," which diminishes their value to others in the classroom.In a learning-communities approach there is also the notion of a community ide ntity. By working toward common goals and developing a collective awareness of the expertise available among the members of the community, a sense of "who we are" develops. In the absence of a learning culture that builds a collective understanding and views its members as learning resources, most classrooms fail to develop a strong sense of community identity.Re source s:Both a learning-communities approach and many classrooms use resources outside of the classroom, including disciplinary experts, telementors, the Web, etc. However, in learning communities both the content learned and the processes of learning from the outside resources are shared more among members of the community and become part of the collective understanding. A further distinction between learning communities and most classrooms is that in learning communities, both the members themselves and the collective knowledge and skills of the community are viewed as important resources.Discourse: In the learning-communities approach the language for describing ideas and practices in the community emerges through interaction with different knowledge sources and through co-construction and negotiation among the members of thecommunity. Also, learning communities develop a common language for more than just content knowledge and skills. The community develops ways to articulate learning processes, plans, goals, assumptions, etc. In contrast, in most classrooms the teacher and texts tend to promulgate the formal language to be learned.Discourse functions in a learning community as a medium for formulating and exchanging ideas. It serves to motivate the research and reflection in the community by raising new questions and hypotheses, which give rise to further research and understanding (Bereiter & S cardamalia, 1993). S tudents are expected to provide feedback to each other, and are supported in doing so. In contrast, in most classrooms communication occurs principally between the teacher and students. The discourse functions as a medium for conveying knowledge to students and asking students questions to test their knowledge (S chofield, 1995).Knowle dge: In learning communities the development of both diverse individual expertise and collective knowledge is emphasized. In order for students to develop expertise, they must develop an in-depth understanding about the topics that they investigate. Rich subject matter is important. The topics are not randomly chosen, but rather the depth centers on key principles or ideas in a domain that are generative for understanding a broad array of topics. There is also a circular growth of knowledge, wherein discussion within the community about what individuals have learned leads individuals to seek out further knowledge that they then share with the community. Thus, there is an interplay between the growth of collective knowledge and of individual knowledge, with each supporting the other. In most classrooms the goals tend towards covering all the topics in the curriculum (breadth over depth) and for everyone to learn the same thing.Products: Dweck (1986) has shown how students who adopt performance goals put their energy into looking good and tend to give up when they fail. But those students who adopt learning goals learn more from their mistakes and pursue learning in the face of failure. One concern is that an emphasis on products may lead students to adopt performance goals, and focus on production values rather than meaningful learning. But, as Bruner (1996) points out, a culminating event or product can act to focus the energy of the entire class on a joint effort, which helps to build community.In a learning-communities approach, members work together to produce artifacts or performances that can be used by the community to further their understanding. There is sustained inquiry and development of products over months. In contrast, most classrooms tend toward individual or small group assignments with little sharing or collective products. Usually work is produced in short periods of time.Analysis of Learning-Community ClassroomsTo give a picture of what a learning-communities approach implies for schooling, we describe three exemplary cases of learning communities that have been set up in American classrooms. After briefly describing each of the three cases, we will compare them with respect to the eight issues raised in the Introduction. Then we will attempt to extract general principles for the design of learning communities.Scardamalia and Bereiter’s Knowledge-Building ClassroomsS cardamalia and Bereiter (1991, 1994) have developed a model they call Knowledge-Building Communities. CS ILE (Computer S upported Intentional Learning Environments) is the name commonly applied to this model, although strictly speaking it is the name of the computer software they developed, which is used in classrooms that may or may not have adopted the pedagogical model. The essential idea is that students work together to make sense of the world around them and work towards advancing their own state of knowledge and that of the class.The model involves students investigating problems in different subject areas over a period of weeks or months. As students work, they enter their ideas and research findings as notes in an on-line knowledge base. The software (originally called CS ILE, now in a new version called Knowledge Forum) supports students in constructing their notes through features such as theory-building scaffolds (e.g. "My Theory," "I Need to Understand”) or debate scaffolds (e.g. “Evidence For”). S tudents can read through the knowledge base adding text, graphics, questions, links to other notes, and comments on each other’s work. When someone has commented on another student’s work, the system automatically notifies them about it.The central activity of the community is contributing to the communal knowledge base. Contributions to CS ILE can take the form of (a) individual note s, in which students state problems, advance initial theories, summarize what needs to be understood in order to progress on a problem or to improve their theories, provide a drawing or diagram, etc.,(b) vie ws, in which students or teachers create graphical organizations of related notes,(c) build-ons, which allow students to connect new notes to existing notes, and (d) “Rise Above It “note s, which synthesize notes in the knowledge base. Any of these kinds of contributions can be jointly authored.When students feel a note makes an important contribution to the collective knowledge base, they can propose the note for publication. An editorial group and the teacher then decide whether to publish the note. At the end of the school year the class may decide on a selection of notes to remain in the knowledge base for classes that come after them. The goal is to engage students in progressive knowledge building, where they continually develop their understanding through problem identification, research, and community discourse. The emphasis is on progress toward collective goals of understanding, rather than individual learning and performance.Brown and Campione’s FCL ClassroomsBrown and Campione (1994, 1996; Brown, 1992) have developed a model they call Fostering a Community of Learners (FCL) for grades 1-8. The model provides what is termed a "developmental corridor," where the learning community extends not only horizontally across a classroom, but vertically across grades. This makes it possible for learning topics to be revisited at increasing levels of disciplinary sophistication. We will focus here on communities in classrooms, rather than across grades.The FCL approach promotes a diversity of interests and talents, in order to enrich the knowledge base of the classroom community as a whole. The current focus of FCL classrooms is on the subject areas of biology and ecology, with central topics such as endangered species and food chains and webs. There is an overall structure of students (1) carrying out research on the central topics in small groups where each student specializes in a particular subtopic area, (2) sharing what they learn with other students in their research group and in other groups, and (3) preparing for and participating in some “consequential task” (S cardamalia, Bereiter & Fillion, 1981) that requires students to combine their individual learning, so that all members in the group come to a deeper understanding of the main topic and subtopics. Teachers orchestrate students’ work, and support students when they need help.There are roughly three research cycles per year. A cycle begins with a set of shared materials meant to build a common knowledge base. S tudents then break into research groups that focus on a specific research topic related to the central topic. For example, if the class is studying food chains, then the class may break into five or six research groups that each focus on a specific aspect of food chains, such as photosynthesis, consumers, energy exchange, etc. S tudents research their subtopic as a group and individually, with individuals "majoring" by following their own research agendas within the limits of the subtopic. S tudents also engage in "crosstalk," talking across subtopic groups to explain, ask questions, and refine their understanding. The research activities include reciprocal teaching (Palincsar & Brown, 1984), guided writing and composing, consultation with subject matter experts outside the classroom, and cross-age tutoring. In the final part of the cycle, a member from each of the subtopic groups come together to form a “jigsaw” group (Aronson, 1978) in order to share learning on the various subtopics and to work together on some consequential task. Thus, in the jigsaw, all pieces of the puzzl e come together to form a complete understanding.The consequential task requires the different subtopics to be used together to form a common product or common understanding. The choice of consequential tasks is ideally made by the teacher and students together. In some cases the consequential task might be a bulletin board display, the design of a bio-park to protect an endangered species, a presentation to the community at large, or in some cases a test of students’ knowledge. These tasks “bring the research cycle to an end, force students to shareknowledge across groups, and act as occasions for exhibition and reflection” (Brown & Campione, 1996, p. 303).Lampert’s M athematics ClassroomLampert (1986, 1990; Lampert, Rittenhouse & Crumbaugh, 1996) taught mathematics to fifth grade students for a number of years, where she developed an approach to teaching that reflected her view of an idealize d mathematics community. The class usually starts with a problem posed to the students, which they work on alone or in groups, developing their solutions in notebooks that retain all their work during the year. After 15-20 minutes of work the class as a whole discusses the problem and various possible solutions. Lampert encourages students to discuss different ideas and solutions, so that they develop a deep understanding of the mathematical principles underlying their work.Lampert chooses problems that foster deep inquiry and mathematical argumentation by students. S tudents are encouraged to present different ideas and methods, and to discuss which are correct and why. There is an emphasis on how to resolve mathematical arguments by appeal to logic and evidence. Participating in the mathematical discussions, learning how to make mathematical arguments, and learning the language of mathematics (terms such as “conjectures” and “commutativity”) are the central activities in the classroom.Lampert orchestrates the discussion and picks up on certain ideas, revoicing them so that everybody can understand. S he is very much in control and uses various techniques to make sure students participate in the discussion. S he opportunistically follows the ideas the students suggest in order to relate them to important mathematical ideas. The students are on an equal footing in the discussions, offering their ideas and discussing other students’ ideas and arguments. S he carefully orchestrates the discussion to maximize the participation among the students. Her technique of asking students to explain other student’s ideas is particularly effective in making them listen to and respect other students. The discussion involves students in a way that fosters understanding of the ideas and principles that the class is developing.Comparison of the Three CasesWe will compare the three cases in terms of the eight issues outlined in the Introduction. By looking at the similarities and differences between these exemplary cases of classroom learning communities, we can more clearly see the essential characteristics of learning communities.Goals: All three cases foster a culture of learning, where students come to see themselves as contributors to their own learning and that of the community. The goals in all three cases are consonant with the learning-community goals described in the Introduction. This includes the goals of students learning how to (1) learn and reflect on their learning, (2) become critical thinkers who know how to frame questions anddevelop a deep understanding of the issues they investigate, and (3) share their learning and work with others in the community as resources.Le arning activitie s: While the three cases share the same goals, they involve different learning activities and types of support. In CS ILE, students investigate problems and develop theories, contribute written and graphic descriptions about what they are learning to the collective knowledge base, and comment on and respond to other students’ contributions. This tends to be accompanied by oral discussion.These learning activities are guided by the software through the different scaffolds (e.g., “My Theory,” “What I Learned”) and by interactions with other students around their ideas. In FCL, the learning activities center on research, sharing knowledge, and producing joint products.The different activities (e.g., reciprocal teaching, guided writing, cross-age tutoring) each have a structure, which serves to guide the students. Lampert’s classroom focuses on problem solving and mathematical argumentation as learning activities. Lampert provides guidance throughout the process, by posing provocative problems and directing discussion toward important mathematical issues.Te ache r role s and powe r re lationships: In all three classrooms, the teacher takes the role of a facilitator. The learning activities and lines of inquiry tend to be driven by student questions and interests. In Lampert’s classroom, by comparison with CS ILE and FCL, the teacher is much more in control of what students are doing. By leading students in whole class discussion, Lampert supports students in coming to reason and argue mathematically in the ways that she has mastered. The teacher’s role in CS ILE is not prescribed and can vary widely, depending on the teacher’s knowledge and orientation toward a particular unit. As S cardamalia, Bereiter, and Lamon (1994, p. 209) point out "CS ILE opens up a significant channel for communication in the classroom that is not mediated through the teacher." FCL falls somewhere in between. Certain activities, such as the benchmark lessons, are closely guided by the teacher or by guest experts. However, students also direct the community's learning, as in one case where students became interested in the question of whether mosquitoes could transmit AIDS (Brown & Campione, 1994).In both CS ILE and FCL classrooms a student may have more expertise in a particular area than the teacher, changing the typical student-teacher power relationship that exists in most classrooms. Ideally, students benefit from the knowledge of their teachers and available experts, but at the same time go beyond such knowledge whenever feasible (S cardamalia & Bereiter, 1991).Ce ntrality/pe riphe rality and ide ntity: As stated earlier, the central roles are those that directly contribute to the collective activities and knowledge of the community. All three cases also provide a means for all community members to participate in peripheral roles to whatever extent is possible. In CS ILE, students can still participate in the community while engaging in peripheral activities, such as reading notes in the knowledge base and making comments on other students' notes. S tudents' roles begin。
