Interactive Display Design And Research Of Junior Middle School Chemistry Knowledge Tree To Cognitive Effciency

As an enlightenment course for chemistry learning,junior high school chemistry is with complicated knowledge,scattered,conceptual abstraction,and experiment-oriented features.Therefore,students are under greater cognitive pressure.Knowledge tree,as an important tool for knowledge construction,can both sort out the complicated knowledge points and establish knowledge network.It is often used in chemistry learning.However,traditional knowledge tree expression is lacking in interactivity.Knowledge points still need mechanized memory.Digital media technology is used to interactively innovate the chemical knowledge tree.This will help students improve their cognitive efficiency in chemical learning,stimulate their interest in chemistry learning.At the same time,it can provide students with a new way of learning.The interactive display design of the junior school chemistry knowledge tree is based on the requirement analysis.It is designed on the principle of interaction design.Through the analysis of the characteristics of junior middle school chemistry subject knowledge system,students' cognitive efficiency,the advantages and limitations of traditional knowledge tree expression,and the analysis of learning needs based on students' cognitive efficiency,the analysis is conducted from the object to the subject.In order to improve cognitive efficiency,we propose design concepts that meet the cognitive efficiency,user experience theory,knowledge structure,content visualization,interactive naturalization,and interesting design principles,and user mental models.Interactive display of junior high school chemistry knowledge trees for cognitive efficiency,including frame design,simple and friendly interface,interesting visual elements,interactive operation interfaces,and clear knowledge structure through the construction of interactive and editable knowledge trees.The interactive display and interactive display of the periodic table of the elements show the knowledge content.By the construction of virtual labs and visual tags,the roaming scene is realized.In the principle of naturalized interaction,the first-person roaming interactive function is designed.With the lightweight experimental scene and friendly experimental process design,naturalized and friendly interaction of experimental operations is realized.Finally,the Unity platform is used for system design integration and interaction.By means of a comparative experiment,the authors consider whether the design can improve the cognitive efficiency of students by the time which the test is completed and the correct answer rate.The heuristic evaluation method was used to analyze whether the visual performance and interaction mechanism is well or not.The above can identify problems,and propose directions for improvement.In summary,interactive display of the junior high school chemistry knowledge tree which designed for cognitive efficiency combines digital media interaction technology with the expression of traditional knowledge trees.Meanwhile,it tries a new type of knowledge expression and learning methods to stimulate students' interest in learning.It improves students' cognitive efficiency of chemistry learning in junior middle schools.Finally,it explores a new way of interactive learning for cognitive efficiency in the digital age.
