Geometrical Tools to Teaching Azeotropy Using Simplified Thermodynamic Models
by Gustavo Platt, F.S. Lobato, F. D. Moura Neto, G.B. Libotte, D.A. Goulart
Abstract: In this work we propose a geometric view of the azeotropy problem, using some simplified models. We demonstrate that the occurrence of azeotropes in binary mixtures can be viewed - geometrically - as the intersection of curves in the plane (for some models, these curves are parabolas). Furthermore, the idea of functions from the plane to the plane is used to understand the azeotropic phenomenon. These ideas are illustrated with two simple cases, with one and two azeotropes, allowing the analysis of a nonusual thermodynamic behavior -- such as double azeotropy -- with simple mathematical tools, by undergraduate students in Chemical Engineering courses.

Adaptive Optimisation Algorithm for Online Teaching Behaviour
by Jin-hua Zhu
Abstract: In order to optimise the weakness of Teaching Learning based Optimisation Algorithm (TLBO), which are characterized by slower convergence in convergence, lower accuracy, and easy to fall into local optimum. To improve the efficiency and shortcomings of the algorithm, it is believed that there are two mechanisms to optimise. The first is based on the mechanism of mutual learning among multiple teachers. The second is based on the mechanism of adaptive step size improvement. First of all, by setting up multiple teachers to teach in the TLBO algorithm, the diverse nature of the population can be preserved. Teachers can also explore and learn from each other and students can improve their learning efficiency. The algorithm is improved in the precision of optimisation, and the algorithm is improved on the weakness of local optimisation.

Student-Parent Teams: A 10-Year Retrospective Study of an Undergraduate Research Experience
by James Giancaspro, Nam Ju Kim
Abstract: The objective of this study was to investigate the long-term (10-year) impact of a small, yet unique, outreach effort where three teams of undergraduate students were paired with their parental counterparts to conduct civil engineering research supported by the United States' National Science Foundation. Those students are compared to a control group of undergraduates who participated in a traditional research experience and were exposed to the same conditions and research project. A survey instrument was used to collect data related to the participants' actual career path trajectory, self-efficacy, scholarly productivity, and parental influence in their decisions for postgraduate education and career planning. Parental support for students' postgraduate plans either remained unchanged or increased following the research experience. While the participants in the student-parent teams produced more scholarly products than the control group in the decade following the experience, the sample size is too small to draw causal inferences.

Design of step-by-step teaching system for English writing based on cloud network technology
by Mian Wang
Abstract: Aiming at the problems of low user satisfaction, low user interaction accuracy and high user help-seeking rate in the step-by-step teaching system of English writing designed by the present method, a step-by-step teaching system of English writing based on cloud network technology is proposed. In the functional module design part of the system, the foreground and background display modules of the system are designed. The front-end display module includes online question answering, video learning, data learning, etc. The back-end display module includes learning and data management, the design of step-by-step teaching website for English writing, online learning system and teaching mode. Through the design of functional modules and step-by-step teaching website of English writing, the design of step-by-step teaching system of English writing is finally completed. The experimental results show that the system designed by this method has higher user satisfaction, higher user interaction accuracy and lower user help-seeking rate.

The evaluation method of English teaching efficiency based on language recognition technology
by Bing Hu
Abstract: At present, there are some problems in the evaluation methods of English teaching efficiency, such as poor significance of indicators, low evaluation efficiency and low evaluation accuracy. This paper proposes an evaluation method of English teaching efficiency based on language recognition technology. Language recognition technology is used to identify English sentences through error detection, eigenvalue extraction, pronunciation evaluation, phoneme association and phoneme recognition. The overall structure of English teaching efficiency evaluation is constructed by B/S structure, and the weight of evaluation indicator is calculated by AHP combined with hierarchical relevance theory. The degree of relevance is obtained, and the evaluation of English teaching efficiency is completed by ranking the degree of relevance. The experimental results show that the proposed method has high significance, high evaluation efficiency and high evaluation accuracy.

Design of interactive English reading teaching system based on hybrid communication network
by Yang Le
Abstract: In order to overcome the problem of long response time and poor interaction in traditional English reading teaching system, an interactive English reading teaching system based on hybrid communication network is proposed. The hardware part of the system is composed of seven modules, among which the course management module mainly adopts the combination of file system and multimedia attribute database to manage the uploaded data of teachers. Students use the hyperlink location field to mark the connection location of the media, can see more colourful learning pages, to achieve the interactive design of the teaching system. In the software part, the learning evaluation model is constructed by covering method or error method to realise the comprehensive evaluation of students' learning state. Simulation results show that this method can comprehensively understand and evaluate students' learning status and knowledge points, shorten the response time of the system, and has great advantages.

Research on evaluation method of students' classroom performance based on artificial intelligence
by Yang Liu, Huaxi Chen, Anjahol Thoff
Abstract: In order to solve the problem of time-consuming and low reliability of the traditional evaluation method for students' classroom performance, an artificial intelligence-based evaluation method for students' classroom performance is proposed. This paper establishes the evaluation standard of students' classroom performance and quantifies the evaluation of students' classroom performance. Classroom monitoring device is driven by program code. The initial acquired image is processed by image enhancement and recognition, and the result is transmitted to the upper computer. This paper analyses the evaluation indexes of students' classroom performance, such as attendance, participation, attention and abnormal behaviour, and finally outputs the results of teachers' classroom performance. The experimental results show that compared with the traditional evaluation method, the artificial intelligence-based evaluation method saves 69 seconds on average and improves its reliability by 6.25%.

Research on integration method of AI teaching resources based on learning behaviour data analysis
by Xiaohua Yang
Abstract: Aiming at the problem of long running time and low precision of traditional artificial intelligence resource integration method, a new artificial intelligence teaching resource integration method based on learning behaviour data analysis is proposed. Analyse online learning behaviour data, extract relevant data of artificial intelligence teaching resources, and realise sample collection of artificial intelligence teaching resources. Random forest algorithm was used to classify them, reward and punishment factors were added, and mountain-climbing method was used to search the solution space, so as to realise the integration of artificial intelligence teaching resources. The experimental results show that this method can improve the efficiency and precision of the whole method, and obtain better integral results.
