基于虚拟仿真实验的《植物组织培养技术》教学改革实践研究

Plant Tissue Culture Technology Based on Virtual Simulation Experiment Practical Research on Teaching Reform

《植物组织培养技术》是一门理论与实践技术紧密结合的课程,也是生物专业的核心基础课程。然而,在过去的教学实践中,存在学生对植物组织培养理论知识的理解和掌握不够、实践训练受到教学资源、平台和时空限制、实验成功率较低、成果转化率低等问题。本文在分析《植物组织培养技术》教学情况的基础上,围绕“立德树人”总目标,遵循“以学生为中心”基本原则,以虚拟仿真实验平台及智慧教学为重要载体,探索“线上”与“线下”有机结合、“教”与“学”深度融合、“理论”与“实践”高度契合、“课前 + 课中 + 课后”协同推进的教学模式。通过对有效教学模式改革的全面探索,有效提高了学生对于课程的学习兴趣与学习积极性,弥补了该课程实验环节存在的耗材损耗量大、植物培养条件高、实验设备昂贵等一系列问题,为实验教学提供了有效补充,也为后续《植物组织培养技术》课程教学改革提供了理论依据。

Plant Tissue Culture Technology is a course that combines theory with practice, and it is also the core basic course of biology. However, in the past teaching practice, there were problems such as students’ insufficient understanding and mastery of theoretical knowledge of plant tissue culture, practical training restricted by teaching resources, platforms and time and space, low success rate of experiments and low transformation rate of results. Based on the analysis of the teaching and learning of Plant Tissue Culture Technology, this paper focuses on the general goal of “building moral and educating people”, follows the basic principle of “student-centered”, takes the virtual simulation experiment platform and intelligent teaching as the important carrier, and explores the teaching mode of organic combination of “online” and “offline”, deep integration of “teaching” and “learning”, high integration of “theory” and “practice”, and collaborative promotion of “before + during + after class”. The comprehensive exploration of effective teaching mode reform has effectively increased students’ interest and enthusiasm in the course, compensated for a series of problems in the experimental aspects of the course, such as high loss of consumables, high plant culture conditions and expensive experimental equipment, and provided an effective supplement to experimental teaching, as well as a theoretical basis for the subsequent teaching reform of the course Plant Tissue Culture Technology.
