The essential purpose of this research study is to determine the public perceptions of nanotechnology research, describe the risks and benefits also trust between them. This research study was also conducted in Chine to determine the perception of nanotechnology. This research study depends upon primary data analysis to describe theoretical concepts related to the risk, benefits, and trust of nanotechnology. This research study also depends upon the observation of research participants about nanotechnology. For this purpose, develop different research questions and fulfill these questions from local participants who know about nanotechnology. Smart PLS software was utilized to measure the research study's findings. It produced informative results that included the R square, Total effects, significant analysis, and descriptions of the path coefficient analysis and the combined effects of graphical analysis between them. The result found that some public perception is positive thinking about nanotechnology and some negative also that nanotechnology plays a vital role in every field of industries.
The teaching of solid geometry plays an essential role in cultivating students' spatial imagination ability. In the traditional teaching method, teachers often operate by themselves to avoid the damage of teaching tools. Students can only observe passively, which is easy to produce a sense of boredom to study. Moreover, abstract geometric features and phenomena are not intuitive enough for students to form a correct cognition of solid geometry. In this paper, we designed an inquiry geometry learning environment by using virtual reality technology. Students can interact with the virtual geometry model to promote immersive, interactive, and inquiry learning to improve students' understanding of geometric structures and features. To study the influence and application effects of virtual geometry learning environment on students ' learning knowledge level, we recruited 60 seventh grade students (aged 13-14 years) and randomly divided them into VR teaching group (N=30) and control group (N=30). Students in the VR teaching group conducted gesture-based inquiry learning in the virtual geometry learning environment, while students in the control group used traditional methods to learn. The test of geometry knowledge before and after the experiment indicates that the virtual geometry learning environment positively impacts students' acquisition of geometry knowledge. The questionnaire survey results show that the students' subjective perception of usability and willingness to use score high. Virtual reality and gesture interaction techniques can help students visualize geometric abstractions and facilitate their understanding, and students have shown a strong desire to continue learning using related technologies.
The continuous expansion of technological innovation and big data technology to various fields has brought great challenges to the reform of high school education. This work intends to improve the teaching effect of classical poetry in high school Chinese teaching, change the traditional teaching method, improve students' subjective initiative and practical ability, and improve the teaching effect of classical poetry under the traditional philosophy. The Outcome-based Education (OBE) teaching philosophy and the personalized recommendation algorithm of teaching resources based on Convolutional Neural Network (CNN) are applied to the teaching of classical poetry in high school. The teaching objectives, teaching process and teaching activity evaluation are designed. The model design is applied to the teaching of the experimental class, and the results of the application of the design model are comprehensively evaluated through comparison. The result shows: (1) Through the evaluation and analysis of teaching strategies, the satisfaction of pre-class preparation strategy, classroom teaching implementation strategy and after-class teaching evaluation strategy design mode is higher than that of traditional teaching mode. In particular, the satisfaction of teaching results in class 1 and class 2 are 95.1 % and 93.3 %, respectively, while that in the control class is only 62.6 %. (2) The teaching implementation process is evaluated. Comparisons are made from the exploration of teaching activities, the interaction between teachers and students in the classroom, and the recommendation of teaching resources. (3) The application effect of the design model is evaluated. The satisfaction degree of the experimental class is higher than that of the control class in terms of learning attitude, learning ability and academic performance. (4) The satisfaction of the design model is higher than other teaching models in terms of student recognition, goal achievement and teaching effect. It aims to innovate the teaching methods of high school poetry appreciation, provide some reference for teaching reform, and provide some ideas for the subsequent application curriculum.
In order to solve the teaching problems such as the single form of traditional teaching mode and the unsatisfactory effect of classroom teaching, this paper proposes a new teaching mode based on the fusion of multimodal multimedia information. The main research contents are: Firstly, the concept of modal and multi-modality is expounded in detail, and the representation form of modal carrier multimedia is described in detail. Secondly, the problems existing in traditional teaching are analyzed. Finally, in Solutions Statistical Package for the Social Sciences (SPSS), the normal equation is solved by using the least square method, and the statistical data is saved in the data file to realize the nonlinear analysis of the data to realize the change of multimodal information technology in preschool education by using nonlinear analysis technology. The results show that in the traditional preschool education mode, the number of students with good learning status in the class is always kept at 20%, and the number of students with poor learning and ordinary learning is almost the same. In the multi-modal teaching mode, the number of outstanding students is increasing by 12% every week, accounting for 60% in the last week, which is more than half of the number of normal classes. It clearly shows that students feel the innovation and interest of multi-modal technology integration teaching, and have a high interest in learning. After the integration of multimodal information technology, the teaching classroom of preschool education has become rich and the students' practical ability has been improved. The research in this paper provides a theoretical basis for the integration of multimodal information technology in college teaching, which is helpful for more research on improving the quality and effect of classroom teaching in colleges and universities in the future.
In recent years, frequent occurrence of major emergencies in our country not only endangers social stability, causes loss of life and property, but also has a huge impact on psychology of audience. crisis. In order to minimize psychological impact of sudden public crises on audience, it is necessary to conduct in-depth research on group psychological service process under sudden public crises. According to characteristics of sudden public crisis events and psychological services, this paper analyzes reasons for psychological service reactions of individuals, mainly from external and internal aspects, and proposes that psychological service process mainly includes three stages: psychological service The formation, development and termination of psychological service in three stages are described in detail, and feasibility of Agent modeling of group psychological service is analyzed. And put forward intervention measures of psychological service, mainly starting from social support and crowd environment, respectively changing intensity of social support and size of crowd environment to intervene in psychological service process of group, which is beneficial to emergency management of sudden public crisis events in our country. policy recommendations.
