模块三知识能力试题答案一、名词解释1、饭店人员培训一个有用的饭店培训可以理解为一个系统过程。在这个过程中企业的人力资源通过指导和实践活动获得知识、培养技能、改变态度、增进能力，从而提高企业整体的绩效。2、培训需求分析需求分析就是通过对酒店及其成员的现有状况与理想工作状况的差距进行分析，来确定是否需要培训以及培训的内容的系统方法。需求分析具有很强的指导性，它既是确定培训目标、设计培训计划的前提，也是进行培训评估的基础。3、交叉培训又称工作轮换，指让受训人有计划地从一个岗位换到另一个岗位，以使员工熟悉不同部门或岗位的业务，具备多项专业技能。4、TSFC四步培训法具有科学性的“TSFC四步培训法”，即准备（Tellyou）课前准备并告知学员培训的相关知识和技能示范（Showyou）示范和重复培训步骤练习（Followme）学员在培训师指导下对所学知识和技能进行练习。检查与跟踪（Checkyou）对学员完成的任务进行检查并给予积极支持和及时反馈。二、填空题1、培训评估主要从（反应）（学习）（行为）（结果）四方面进行。2、培训目标主要分为：技能培训、知识传授和（增强能力）。3、培训的特点是（针对性）（多样性）（速成性）（持续性）（强化外语培训）。4、培训应遵循（成人学习）原则。三、单项选择题师傅带徒弟这种培训方式的开发主体是(

D

)。

A.师傅

B.徒弟

C.学校

D.企业或单位在欧美、日本等国家盛行的，不经培训或培训不合格不得进入岗位的培训形式是(C

)。

A.在职培训

B.非在职培训

C.岗前培训

D.脱产培训下列哪项不是在培训过程中教室布置的决定因素（D）。A.参训人员人数B.培训活动形式C.课堂控制程度D.学员参与程度4.下列哪项不是培训的“Learn”教育方法的内容：（E）A.多讨论B.重视经历C.积极参与D.相关内容E.游戏5.培训目标是学员接受培训后所表现出来的工作能力水平的描述。培训目标的要求不包括：(B)A.清楚B.简单C.具体D.可衡量6.培训过程中最复杂最费时的阶段是：(D)A.培训评估B.培训需求分析C.培训设计D.制作培训资料7.“你喜欢这样的培训吗？”“你对培训师的表现是否满意？”这属于培训评估方面的（A）层面。A.反应B.学习C.行为D.结果8.OJT指的是（B）A.职前培训B.在职培训C.脱岗培训D.交叉培训9.提出一些工作中有代表性的问题，并假设几种解决问题的方法，让员工讨论和选择正确答案，并申明理由，并由指导教师做出综合分析的一种方法是：（D）A.角色扮演B.案例分析C.操作示范D.情景模拟四、简答题1、描述角色扮演法的实施过程和优缺点。是让员工模拟实际情景，扮演各种角色进行训练的趣味性很强的一种方法，从而改进和提高自己在职位上表现出的态度与行为。这种培训方法多用于改善人际关系的训练。主管与属员之间，销售人员、服务人员与客人之间，领班与服务员之间，由于所在职位不同，感受与态度也常不同。因此，角色扮演法的做法是：让员工扮演与自己工作相关的另一职位上的角色，并进行模拟，亲自体验对方的感受，消除员工之间、员工与管理者之间、管理者之间的隔阂、以达到相互沟通与理解的培训目的。其缺点在于其情景的人为性，降低了情景的现实性；角色扮演更强调个人，不重视集体，不利于培养受训者的团队精神。2、简述培训的意义。1.培训对饭店的意义（1）适应环境的变化，满足市场竞争的需要（2）增强企业稳定性和凝聚力。（3）有效减低损耗和劳动成本（4）全面提高劳动效率，提升服务质量（5）改善饭店“非专业化”的现状，提升饭店形象。2.培训对员工的意义（1）培训可以提高员工素质（2）增强员工的自信心和安全感。（3）为员工晋升创造条件，促进职业发展。3、说明培训需求分析的层次和内容。（1）组织分析(OrganizationAnalysis)确定培训需求的第一步是把饭店作为一个整体进行检查，分析饭店的组织目标和经营目的，来确定完整的、有针对性的培训需求。要通盘考虑哪些技能和体系能最有
