摘要： BackgroundEarly exposure to Computer Science (CS) and Computational Thinking (CT) for all is critical to broaden participation and promote equity in the field. But how does the introduction of CS and CT into primary school curricula impact learning, perception, and gaps between groups of students?MethodologyWe investigate a CS-curricular reform and teacher Professional Development (PD) programme from an equity standpoint by applying hierarchical regression and structural equation modelling on student learning and perception data from three studies with, respectively, 1384, 2433 and 1644 grade 3-6 students (ages 7-11) and their 83, 142 and 95 *** learning, exposure to CS instruction appears to contribute to closing the performance gap between low-achieving and high-achieving students, as well as pre-existing gender gaps. Despite a lack of direct influence of what was taught on student learning, there is no impact of teachers' demographics or motivation on student learning, with teachers' perception of the CS-PD positively influencing learning. Regarding perception, students perceive CS and its teaching tools (robotics, tablets) positively, and even more so when they perceive a role model close to them as doing CS. Nonetheless, gender differences exist all around with boys perceiving CS more positively than girls despite access to CS education. However, access to CS-education affects boys and girls differently: larger gender gaps are closing (namely those related to robotics), while smaller gaps are increasing (namely those related to CS and tablets).ConclusionThis article highlights how a CS curricular reform impacts learning, perception, and equity and supports the importance of (i) early introductions to CS for all;(ii) preparing teachers to teach CS all the while removing the influence of teacher demographics and motivation on student outcomes;and (iii) having developmentally appropriate activities that signal to all groups of students.

关键词： Graduate admission   Statistical analysis   Partiality patterns   Gender equality   Nationality diversity  

摘要： Although different organizations have defined policies towards diversity in academia, many argue that minorities are still disadvantaged in university admissions due to biases. Extensive research has been conducted on detecting partiality patterns in the academic community. However, in the last few decades, limited research has focused on assessing gender and nationality biases in graduate admission results of universities. In this study, we collected a novel and comprehensive dataset containing information on approximately 14,000 graduate students majoring in computer science (CS) at the top 25 North American universities. We used statistical hypothesis tests to determine whether there is a preference for students' gender and nationality in the admission processes. In addition to partiality patterns, we discuss the relationship between gender/nationality diversity and the scientific achievements of research teams. Consistent with previous studies, our findings show that there is no gender bias in the admission of graduate students to research groups, but we observed bias based on students' nationality.

摘要： The safety monitoring system has been used to monitor and manage engineering safety operation. The application scope of the safety monitoring system is very wide. It has a wide range of applications in the fields of pipeline safety monitoring, electrical safety monitoring and household safety monitoring. This article studied the application process of the household safety monitoring system. Many home safety accidents are caused by inadequate monitoring of safety problems. Therefore, it is very important to establish a household safety monitoring system. Traditional home safety monitoring systems only rely on cameras for safety monitoring, and the traditional home safety monitoring system uses too few sensors. With the continuous development of wireless sensor network (WSN) technology, it is possible to build a sensor node network, but provides real-time information for home security monitoring to the greatest extent. This article compared the home safety monitoring system based on the WSN technology of artificial intelligence (AI) with the traditional home safety monitoring system. The experimental results showed that in the large-scale home environment, the average monitoring accuracy of the traditional home security monitoring system and the home security monitoring system based on the WSN technology of AI was 77.76 and 89.36%, respectively. In the small-scale home environment, the average monitoring accuracy of the traditional home safety monitoring system and the home safety monitoring system based on the WSN technology of AI were 87.63 and 94.43%, respectively. Monitoring accuracy refers to the accuracy of the household safety monitoring system in detecting safety issues. Therefore, the application of the WSN technology based on artificial intelligence to the home safety monitoring system can effectively improve the accuracy of home safety monitoring.

摘要： The "Dear Neighbor" is a crucial value and part of the mission for Chestnut Hill College. Starting in Spring 2021, the Computer Science Department developed an On-Site Internship Program that blends mission, experiential learning requirements, and community outreach to offer real-world experience in website and mobile application development. The program focuses on serving the "Dear Neighbor," working with neighborhood organizations, often nonprofits, in Philadelphia. Many organizations (or clients) are committed to social change, peace, environmental impact, and service.

摘要： Retention of female students in advanced computer science is a well recognized weakness in both K-12 and higher education. The absence of "a feeling of belonging" is often indicated as an important obstacle for students in underrepresented groups. To promote a sense of belonging, we created a "buddy system" to help encourage female students to continue on to the most advanced computer science courses in a high school curriculum. Female students that participated were able to select which students would be in their class. This initiative doubled the enrollment of female students.
