基于PBL教学法与开放式实验相结合的高中生物实验教学模式应用与实践
Application and Practice of High School Biology Experiment Teaching Mode Based on PBL Teaching Method Combined with Open Experiment

针对传统高中生物实验教学中实验操作机械重复、课时有限、教学缺乏深度、设备匮乏、学生参与受限、评价体系亟待完善等问题，建立以问题为基础(PBL)教学法与开放式实验相结合的高中生物学实验教学模式，旨在激发学生探究欲望、培养学生的动手能力及科学素养。通过教学实践证明，该教学模式能够显著提高学生学业成绩，从而提高高中生物实验教学质量。因此，PBL教学法与开放式实验相结合的实验教学模式值得在高中生物学实验教学中广泛推广与应用。
In response to the issues prevalent in traditional high school biology experiment teaching—such as mechanical repetition of experimental procedures, limited class hours, superficial teaching content, scarcity of equipment, restricted student participation, and an evaluation system in need of improvement—a novel teaching model integrating Problem-Based Learning (PBL) with open experiments has been established. This model aims to stimulate students’ curiosity, enhance their hands-on skills, and cultivate their scientific literacy. Empirical evidence from teaching practices demonstrates that this approach significantly boosts students’ academic performance, thereby elevating the quality of high school biology experiment instruction. Consequently, the experimental teaching model that combines PBL with open experiments is highly recommended for widespread adoption and application in high school biology experiment education.
