【摘要】：随着以计算机技术和多媒体技术为核心的信息技术在教育领域的广泛应用,PPT课件辅助教学的运用已在广大教师当中呈现常态化趋势。生物学是研究生命活动规律及其与环境关系的科学,包含宏观和微观两个知识层面。相对其它学科而言,许多高中生物学知识既抽象又难理解,运用PPT可帮助教师将抽象的知识更形象、更具体、更客观地展示出来,亦可将微观的生物规律以生动的图片或视频等形式呈现给学生,有利于学生更容易理解和掌握生物学知识。新入职教育阶段是教师职业生涯中的关键时期。高中生物新教师刚入职时,由于教学时间短、教学经验不足等原因,在PPT使用上遇到诸多问题,影响了PPT辅助教学效果的发挥,阻碍了信息技术与生物课程深层次整合,影响课堂教学效果。因此,如何帮助刚入职的高中生物教师解决PPT使用中存在的问题,使他们能快速、科学、高效和合理地使用PPT技术,使它成为服务学生的有力的教学工具,便将成为新教师所面临的重要课题。本研究的主要目的是通过个案研究找出高中生物新教师在使用PPT课件进行辅助教学时存在的主要问题,并针对这些问题提出合理的优化策略,帮助高中生物新教师能够尽快适应“PPT教学”并掌握PPT使用技术,提高PPT课件辅助生物教学的效果,充分发挥PPT教学优势,更快更好地提高生物教学效果。本研究随机选取了具有代表性的江苏省四名高中生物新教师为个案研究对象,采用文献阅读分析、观察、个案研究等方法,通过调查基本信息、听课观摩、课后访谈等方式,结合个性与共性分析,找出了高中生物新教师在使用PPT过程中普遍存在的主要问题：缺少对新教师使用PPT的岗前培训；对PPT使用存在依赖性；PPT设计与制作存在不规范；照搬照读PPT课件,与学生和教材实际脱节,导致学生产生厌倦排斥心理；幻灯片数量太多,切换速度太快,学生跟不上课件放映的速度；PPT使用过程中与学生互动少：计算机、投影仪等设备出现故障,导致PPT无法正常使用。针对上述存在的问题,本文从教师自身与学校两个方面提出了解决相应问题的优化策略。新教师自身方面：提升新教师使用PPT的理论素养；规范新教师PPT设计与制作：将PPT课件使用和传统教学手段相结合；使用PPT课件要注意掌握切换的节奏；适时适机使用PPT,加强和学生交流。学校方面：适时对计算机、投影仪等设备进行检测维修；定期组织新教师使用PPT的培训；设立专门的PPT技术指导岗位；组织适当的公开课活动,全面提升新教师的教学水平。
[Abstract]:With the extensive application of information technology with computer technology and multimedia technology as the core in the field of education, the application of PPT courseware assistant teaching has shown a trend of normality among teachers. Biology is the study of the law of life activity. And its relationship with the environment, Compared with other subjects, many senior high school biology knowledge is abstract and difficult to understand. Using PPT can help teachers to display abstract knowledge more vividly, concretely and objectively. The microscopic biological laws can also be presented to students in the form of vivid pictures or videos, It is helpful for students to understand and master biology knowledge more easily. The stage of new entry education is the key period in the teacher's career. When the new high school biology teacher enters the post, the short teaching time, the insufficient teaching experience, and so on, There are many problems in the use of PPT, which affect the effect of PPT assisted teaching, hinder the deep integration of information technology and biology course, and affect the classroom teaching effect. How to help the new high school biology teachers to solve the problems in the use of PPT, so that they can use PPT technology quickly, scientifically, efficiently and reasonably, and make it a powerful teaching tool for students. The main purpose of this study is to find out the main problems of the new biology teachers in senior high school when they use PPT courseware to assist in teaching. Aiming at these problems, this paper puts forward reasonable optimization strategies to help the new high school biology teachers adapt to "PPT teaching" as soon as possible, master the use technology of PPT, improve the effect of PPT courseware assisted biology teaching, and give full play to the advantages of PPT teaching. This study randomly selected four new senior high school biology teachers in Jiangsu Province as the case study object, and used the methods of literature reading analysis, observation, case study and so on, through the investigation of basic information. According to the analysis of personality and commonness, this paper finds out the main problems in the process of using PPT in the new teachers of biology in senior high school: the lack of pre-job training for the new teachers using PPT; There is a dependence on the use of PPT PPT design and production is not standard; copy read PPT courseware, and the actual students and textbooks out of touch, resulting in students tired of rejection, too many slides, too fast switching speed, Students can not keep up with the speed of courseware projection and PPT interaction with students in the process of use: computers, projectors and other equipment failure, resulting in the normal use of PPT. This paper puts forward the optimization strategies to solve the corresponding problems from two aspects of teachers themselves and schools: the new teachers themselves: to improve the theoretical literacy of new teachers using PPT; Standardize the design and manufacture of new teacher PPT: combine the use of PPT courseware with traditional teaching methods; pay attention to the rhythm of switching when using PPT courseware; use PPTs in time, strengthen communication with students. The projector and other equipments are tested and maintained; the training of new teachers using PPT is organized regularly; special PPT technical guidance posts are set up; appropriate open class activities are organized to improve the teaching level of new teachers in an all-round way.
