课程设计:从全生命周期角度看塑料包装材料的环境危害

Course Design:Environmental Hazards of Plastic Packaging Materials from the Perspective of the Whole Life Cycle

将“环境伦理学”中的人与自然相结合的思政观展开,从塑料包装材料中复合软包装全生命周期与环境的层层对接角度出发,贯彻包装人以环境保护为己任的价值维度思政观。通过对复合软包装全部材料要素的全生命周期进行全面探讨,探查其环境危害性,展开环境伦理学解析,开展“知识、能力、价值”三维度教学,在提高学生课程兴趣和专业价值度的基础上,更加指向具有“工程—环境意识的卓越包装人”培养,并提升学生科研兴趣和素养。七步法教学可以体现该模式的教学成效,通过课堂参与度调查,该教学模式对学生吸引力大,大大增强了学生的专业自信,专业兴趣,在知识教学的过程中,提升了学生的能力,树立了环保理念,增强了专业环保能力。

This article explores the ideological and political concept of combining human and nature in"environmental ethics",starting from the perspective of the full life cycle of composite flexible packaging in plastic packaging materials and the hiera rchical connection with the environment,and implementing the value dimension ideological and political concept of packaging people taking environmental protection as their own responsibility.By comprehensively exploring the entire life cycle of all mater ial elements of composite flexible packaging,exploring its environmental hazards,conducting environmental ethics analysis,and carrying out three-dimensional teaching of"knowledge,ability,and value",we aim to enhance students'interest in courses and professional value,as well as cultivate outstanding packaging professionals with"engineering environmental awareness",and improve students'research interests and literacy.The seven st ep teaching method can reflect the teaching effectiveness of this model.Through classroom participation surveys,this teaching model is highly attractive to students,greatly enhancing their professional confidence and interest.In the process of knowledge teaching,it improves students'abilities,establishes environmental protection concepts,and enhances their professional environmental protection capabilities.
