With the reform of the Beijing college entrance examination in 2018, the changes in the education system and the state's strong support for education informatization have improved the educational industry policy environment. The country's policy easing on the education industry is the future trend, and using cutting-edge technology to change the teaching method is the most important. Under such a background, we apply VR/AR 3D and other technologies to middle school biology teaching, highlight key points, break through the difficulties, make students' learning more efficient, teachers' teaching easier, and parents more satisfied.
The VR/AR biology teaching system can reconstruct the text description of the book and the three-dimensional reconstruction of the knowledge points contained in the planar image. The four-dimensional presentation can more easily reproduce the teaching content, which is more conducive to students grasping the life science knowledge and understanding the life phenomenon.
Project Description:
Traditional experiment virtualization: traditional experiments need to consider many issues such as site, equipment and danger, while virtual experiments are vivid, safe and convenient, fully utilize the advantages of new technology to serve teaching, and virtualize traditional experiments, which can effectively reduce costs and reduce experimental risks. Enhance promotion and reusability. In our products, the image shows the operation process and microscopic changes of the phage-infected bacteria experiment, and replaces the complicated operation with the visible image, which helps the students to quickly understand the relevant knowledge, to some extent, to make up for the lack of students' experience and Insufficient means of observation.
Visualization of microscopic composition: In the current routine teaching, molecular-level biological knowledge is usually presented mainly in the form of words and pictures, and we can use VR technology to better reflect the content of the subject through models and animation. For example, using dynamic visualization to present the main links in the process of meiosis is beneficial to students' understanding of procedural knowledge, thus stimulating interest and expanding imagination.
Dynamics of metabolic phenomena: Life is in motion, and change is the norm. Static courseware is difficult to express dynamic processes, and the span of time increases the difficulty for students to acquire knowledge. Based on the knowledge point of double fertilization of angiosperms, from pollination to results, from macroscopic and microscopic, continuous and systematic display of the key process of plant early embryo development, it is conducive to students to form a complete concept and dynamic thinking.
Comprehensive review:
The VR/AR Biology Teaching System is based on the B/S platform and is suitable for educational software on the mobile and PC side. The teaching system uses cloud platform and VR/AR+ naked-eye 3D technology to visualize the biological micro-world and abstract the world. Develop corresponding teaching content for different grades, and join some pre-university courses to expand the knowledge level of students and cultivate students' ability to find problems and solve problems. The currently developed middle school biological module is based on the PEP textbook, covering 15 core concepts of middle school biology teaching. At the same time, it has deeply analyzed and explained the key and difficult content of more than 80 specific teachings, satisfying teachers and students. Demand.
