8B Unit 4 A charity showPeriod 7 Main TaskTitle(课题)A charity show Main taskType(课型)New新授课Period(课时)7Supporting theories(理论支撑)A. 皮亚杰、维果斯基的建构主义学习理论以瑞士儿童心理学家皮亚杰为代表的建构主义学习理论认为，学习者的知识是在一定情境下，借助于他人的帮助，如人与人之间的协作、交流、利用必要的信息等等，通过意义的建构而获得的。因此，学习是一个积极主动的建构过程；知识是个人经验的合理化，而不是说明世界的真理；知识是商谈出来的；学习者的建构是多元化的。因此，建构主义学习理论强调教学必须以学生为中心，强调学生对知识的主动探索、主动发现和对所学知识在原有经验基础上的意义生成，要求教师由知识的传授者、灌输者转变成为学生主动建构知识的帮助者、促进者，学生学习的合作者。B. 情境教学法(Situational Teaching Method)是指在教学过程中，教师有目的地引入或创设具有一定情绪色彩的、以形象为主体的生动具体的场景，以引起学生一定的态度体验，从而帮助学生理解教材，并使学生的心理机能能得到发展的教学方法。情境教学法的核心在于激发学生的情感。情境教学中的特定情境，提供了调动人的原有认知结构的某些线索，经过思维的内部整合作用，人就会顿悟或产生新的认知结构。情境所提供的线索起到一种唤醒或启迪智慧的作用。比如正处于某种问题情境中的人，会因为某句提醒或碰到某些事物而受到启发，从而顺利地解决问题。Aims & demands(教学目标)B: Language skill (语言技能) 1.
