电子类专业的毕业生主要面向中小型电子产品生产企业，在广泛的企业调研基础上，通过对电子产品的生产过程作基本序列分析、职业岗位分析、职业能力分析，可建立基于“电子产品生产过程”的应用电子技术专业职业课程体系。 基于电子产品生产过程、职业岗位、职业能力、职业课程分析的职业导航如下图所示。
由职业导航可知，“电子产品维修技术”课程在基于“电子产品生产过程”的专业课程体系中占据十分重要的地位，它不但是电子产品维修职业岗位课程，而且可以培养学生的电路检测与调试能力、仪器仪表使用能力、电子元器件识别与检测能力、电子产品整机电路的阅读能力。 本课程的前期课程是：电路与电工技能、电子电路分析与实践（模电、数电）、基础英语、计算机基础等。
自我国实行对内搞活、对外开放的经济政策以来，各行各业都获得了前所未有的发展。随着我国工业生产规模的扩大和经济发展水平的提高，教育行业受到了各方面的重视。尤其对高等职业教育来说，近几年在教育部和财政部实施的国家示范性院校建设政策鼓舞下，高职院校以服务为宗旨、以就业为导向，开展工学结合与校企合作，进行了较大范围的专业建设和课程改革，涌现出一批示范专业和精品课程。高职教育在为区域经济建设服务的前提下，逐步加大校内生产性实训比例，引入企业参与教学过程和质量评价。在这种开放式人才培养模式下，教学以育人为目标，以掌握知识和技能为根本，克服了以学科体系进行教学的缺点和不足，为学生的顶岗实习和顺利就业创造了条件。 在高职教育新的教学模式下，各院校不断对专业建设和课程设置进行改革，教学改革的成果最终要反映在教学过程中，其中主要的体现形式为教材创新。电子工业出版社作为职业教育教材出版大社，具有优秀的编辑人才队伍和丰富的职业教育教材出版经验，有义务、有能力与广大的高职院校密切合作，参与创新职业教育的新方法，共同出版反映最新教学改革成果的新教材，为培养符合当今社会需要的、合格的职业技能人才而努力。 近期由我们组织策划和编辑出版的“全国高职高专院校规划教材·精品与示范系列”，主要具有以下几个特点。 （1）本系列教材的课程研究专家和作者主要来自于教育部和各省市评审通过的多所示范院校。他们对教育部倡导的职业教育教学改革精神理解得透彻准确，并且具有多年的职业教育教学经验以及工学结合、校企合作经验，能够准确地对职业教育相关专业的知识点和技能点进行横向与纵向设计，能够把握创新型教材的出版方向。 （2）本系列教材的编写以多所示范院校的课程改革成果为基础，体现重点突出、实用为主、够用为度的原则，采用项目驱动的教学方式。学习任务主要以本行业工作岗位群中的典型实例经提炼后进行设置，项目实例较多雷竞技RAYBET，应用范围较广，图片数量较大，还引入了一些经验性的公式、表格等，文字叙述浅显易懂。增强了教学过程的互动性与趣味性，对全国许多职业教育院校具有较大的适用性，同时对企业技术人员具有可参考性。 （3）根据职业教育的特点，本系列教材在全国独创性地提出“职业导航、教学导航、知识分布网络、知识梳理与总结”及“封面重点知识”等内容，有利于老师选择合适的教材并有重点地开展教学过程，也有利于学生了解该教材相关的职业特点和对教材内容进行高效率的学习与总结。 （4）根据每门课程的内容特点，为方便教学过程我们为教材配备相应的电子教学课件、习题答案与指导、教学素材资源、程序源代码、教学网站支持等立体化教学资源，各位老师在华信教育资源网（或）注册后可直接下载。 这套新型教材得到了许多高职院校老师的支持和欢迎，为了使职业教育能够更好地为区域经济和企业服务，我们热忱欢迎各位职教专家和老师提出意见或建议，如果有新教材的编写思路请与我们联系（邮箱：.cm，电话），共同为我国的职业教育发展尽自己的责任与义务！
