摘要

在新工科建设与一流本科课程建设的背景下，专业课程的教学改革至关重要。针对高分子材料与工程专业塑料工程类课程教学中存在的机械结构抽象、原理理解困难、学生参与度较低等问题，探讨了自制教具应用于课程教学的方法与实践。教学团队基于三维软件和3D打印技术设计和制作了螺杆、挤出机、注射模具等一系列关键结构模型，将平面图片转化为可观察、可操作的实物，应用于塑料成型机械、塑料成型工艺和塑料模具设计课程的课堂教学。同时，为“物流运输塑料包装”课程设计并搭建了多功能产品模拟器及配套数据采集系统，实现了包装保护效果的直观验证。教学实践表明，自制教具的应用将抽象理论具象化，有效激发了学生的学习兴趣，加深了其对专业知识的理解，显著提升了课堂教学效果，为工科专业课程的课堂及实践教学改革提供了有益参考。

Abstract

In the context of emerging engineering education and the development of first-class undergraduate courses

reforming practical teaching in specialized courses is of paramount importance. To address challenges in plastics engineering courses within the polymer materials and engineering program

such as difficulty in understanding abstract mechanical structures and principles and low student engagement

this paper explores the methods and practices of applying self-made teaching aids in course teaching. The teaching team designed and fabricated a series of key structural models

including screws

extruders

and injection molds

using 3D software and 3D printing technology

transforming two-dimensional images into observable and operable objects for application in classroom teaching of Plastics Processing Machinery

Plastics Processing Technology

and Plastic Mold Design courses. Additionally

a multifunctional product simulator and a supporting data acquisition system were designed and constructed for the Logistics Transport Plastic Packaging course

enabling intuitive verification of packaging protection effectiveness. Teaching practice demonstrates that the application of these self-made aids concretizes abstract theories

effectively stimulates students’ interest in learning

deepens their understanding of professional knowledge

and significantly enhances classroom teaching effectiveness. This provides a valuable reference for the reform of classroom and practical teaching in engineering programs.
