论证教学可以促进学生对科学概念的学习，论证教学的充分开展有待于优化教学设计和实施。研究者已指出，适宜的教学策略和互动技术能进一步提升学生的学习效果。研究将VR整合于科学论证教学，并应用于七年级“科学”课中“地球与宇宙”单元，开展准实验研究以探究该方法对初中生科学学习的影响。两个班80名七年级学生参与本次实验，其中，一个班级的40名学生为实验组，使用基于VR的方式展开学习；另一个班的40名学生为控制组，在一般教室环境下开展论证式学习。实验结果表明，整合VR的科学论证教学更能促进学生对科学概念的理解，有助于学生在论证过程中提供证据和反证，提升学生在论证学习过程中的集体效能、批判性思维倾向，而论证教学过程中使用VR并未显著影响学生的认知负荷。研究将为VR应用于科学教学提供参考和更多实践证据。
【英文摘要】：
Argumentative teaching can promote students' learning of scientific concepts, and the full implementation of argumentative teaching awaits optimal instructional design and implementation. Researchers have shown that proper teaching strategies and interactive technologies can further promote students' learning outcomes. A quasi-experimental study is conducted to investigate the impact of VR on middle school students' science learning by integrating it into science argumentative teaching and applying it to the unit "Earth and the Universe". A total of 80 students in Grade 7 from two classes participate in this experiment, with 40 students in one class as the experimental group learning using the VR-based approach and 40 students in the other class as the control group using the argumentative approach in a general classroom setting. The experimental results show that the VR-based argumentative teaching can better facilitate students' understanding of scientific concepts, help students to provide evidence and counter-evidence in the process of argumentation, and enhance students' collective efficacy, critical thinking disposition in the process of argumentative learning. And the use of VR during argumentative teaching does not significantly affect students' cognitive load. This study will provide reference and more practical evidence for the application of VR in science teaching.
