Researchers explored the cognitive process of students by analyzing their eye-tracking data in some specified computer programming tasks. Although there are some quantified analysis and data visualization methods proposed in this area, none of them is designed to visualize the attention migration in debugging task. In this paper, we designed a novel kind of chart, i.e. Attention Cloud Map (ACM), for this purpose. We model the semantic code space into a polar coordinate system, and map the code lines and functions of the test program are mapped into points and sectors. We put the bug line in the center point, and mark the relevant code areas in the code space. By plotting the heat map of the amount of eye fixation attention in given time slices, we can obtain a serial of attention distributions in the code space. Experiment results show that, such attention cloud map can enable us to observe the debugging strategy of individual student, and abstract the average progress of one student group, which can be provide some references for the evaluation of students’ debugging performances.
Based on the index of faculty teaching development from 2000 to 2020, this paper analyzes the current situation of faculty teaching development in newly-established undergraduate universities from the aspects of region, province, school level and the composition of index. The research findings are as follows: the overall development of newly-established undergraduate universities is low, but there are many colleges with better development; Universities in east and northeast regions are better than those in middle and west regions, the development of each province is not sufficient and unbalanced; Universities with specialties in normal education, science, engineering and comprehensives perform better than others; there is a big gap between private and public universities; the teaching competition and teaching reform project are better than others among the dimensions of the index.
With the rapid development of Internet plus and big data, college students are facing many threats and risks of network security. Strengthening the education of network security for college students has become an important problem that needs to be solved urgently in higher education. By analyzing the causes of the problems existing in the current network security education, this paper puts forward some measures, such as building a solid network security barrier, building a perfect network security knowledge system and diversified forms of education, to strengthen the network security awareness and prevention skills of college students.
2020 is destined to be a difficult year. The rapid spread of COVID-19 has brought great impact on public life, public health and even the whole industry. But at the same time, online has been rising. As the most active marketing method in the Internet era, Brand Co branding still plays a role during the epidemic. At present, China has achieved phased victory in the epidemic prevention campaign, and we have also ushered in the post epidemic era of small-scale outbreak of the epidemic. As a major victim city of the epidemic, many brands in the post epidemic era are also continuing to explore new methods of Brand Co branding. In this case, in order to find a new method of liangpin Store Brand Co branding suitable for Wuhan in the new era, the author will use the form of big data and questionnaire to analyze the factors affecting the development of liangpin store Regional Brand Co branding in the post epidemic era through data: first, analyze the factors affecting regional brands from three aspects of packaging, category and policy and put forward suggestions; Second, analyze the factors affecting regional brands from three aspects: purchase convenience, word-of-mouth and selectivity, and put forward suggestions; Third, analyze the factors affecting regional brands from three aspects: purchase price, brand and publicity methods, and put forward suggestions to find the form of Brand Co branding suitable for the post epidemic era.
Walking is an aerobic exercise that can help prevent lifestyle-related diseases. Indoor training using a treadmill or ergometer can be used as a substitute for outdoor walking. However, during such indoor training, sensory conflicts between the vestibular and visual systems may occur, potentially inducing motion sickness. Notably, virtual reality (VR) can be used to create a realistic sensation of outdoor walking. Therefore, the purpose of this study was to develop a VR system for reducing sensory conflicts and evaluating patients' biological conditions. As a result, we gained a deeper understanding of the types of VR images able to reduce sensory conflicts.
