To guarantee the system's scalability and versatility, the system framework is designed to be modular. In the networking function section, we establish a network architecture and apply state synchronization mechanisms to ensure consistent scenarios across multiusers. Additionally, we propose an interaction management model and an evaluation model for collaborative training and evaluation. Two collaborative training modes are designed to enhance the flexibility of the system. To evaluate the effectiveness of our system, we select 72 trainees to participate in a training and evaluation experiment. The evaluation model is validated by comparing it with expert evaluations. The results show that trainees can gain a better understanding of their roles and responsibilities and accurately remember the collaborative operation sequence.

The study presents a concept for constructing a research framework in the realm of computer ethics impact. This involves the introduction of an information fusion model and the utilization of a Dempster–Shafer (D–S) evidence theory algorithm. The information fusion model aims to integrate multiple sources of evidence related to computer ethics, including expert opinions, public attitudes, and legal regulations. Furthermore, the experimental results show that the platform's impact perception was effective in reducing the number of individuals who consider computer ethics unnecessary from 40% to 3%. This finding highlights the potential of this platform for enhancing public awareness and understanding of computer ethics. In conclusion, the proposed information fusion model and D–S evidence theory algorithm offer a valuable tool for conducting early research on the construction of computer ethics. It is of utmost importance to delve into the uncontrollable facets of building computer ethics and to navigate the subject–object dilemma from the standpoint of computer users. This approach is essential in addressing the ethical dilemmas that have arisen due to the rapid advancement of computer technology in today's world.

Thus, there is a need to improve female participation in these fields at all levels. Therefore, this systematic review examined the empirical evidence on the factors affecting girls' participation in STEM subjects. We conducted a comprehensive literature search using electronic databases such as Web of Science, Scopus, EBSCO-host, and Google Scholar. An analysis of 165 scholarly publications was done using a systematic methodology. The study found that only 10% of the studies indicated that girls' poor participation in STEM could be attributed to personal factors and 61% to environmental factors. Additionally, behavioral factors accounted for 29% of the sampled studies, which found that negative attitudes, lack of career plans, lack of collaboration, interest, poor self-concept, self-efficacy, and low motivation were identified as factors that affect girls' participation in STEM subjects. The findings highlight a comprehensive overview of the current knowledge of girls in STEM, providing policymakers, educators, and practitioners with valuable insights into creating an enabling environment that supports more girls in STEM subjects.

Misconceptions related to distributed forces that are typically acquired in introductory Physics courses should be corrected to increase student success in subsequent mechanics coursework. The goal of this study was to develop and assess a guided instructional activity using augmented reality (AR) technology to improve undergraduate engineering students' understanding of distributed forces. The AR app was accompanied by a complementary activity to guide and challenge students to model objects as beams with progressively increasing difficulty. The AR tool allowed students to (a) model a tabletop as a beam with multiple distributed forces, (b) visualize the free body diagram, and (c) compute the external support reactions. To assess the effectiveness of the activity, 43 students were allocated to control and treatment groups using an experimental nonequivalent groups preactivity/postactivity test design. Of the 43 students, 35 participated in their respective activity. Students in the control group collaborated on traditional problem-solving, while those in the treatment group engaged in a guided activity using AR. Students' knowledge of distributed forces was measured using their scores on a 10-item test instrument. Analysis of covariance was utilized to analyze postactivity test scores by controlling for the preactivity test scores. The treatment group demonstrated a significantly greater improvement in postactivity test scores than that of the control group. The measured effect size was 0.13, indicating that 13% of the total variance in the postactivity test scores can be attributed to the activity. Though the effect size was small, the results suggest that a guided AR activity can be more effective in improving student learning outcomes than traditional problem-solving.</p>","PeriodicalId":50643,"journal":{"name":"Computer Applications in Engineering Education","volume":"32 2","pages":""},"PeriodicalIF":2.9,"publicationDate":"2023-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138629863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When operating in an electrical training room, learners often configure complex equipment with a set of multiple wires, components, and tools, and then debug them to ensure normal operation. It requires a large amount of practice to acquire the skills to configure the devices, and it is hard for learners to configure the device without any experience. Furthermore, it is also difficult to have hands-on practice when there is not enough physical equipment on site or learners cannot be there in person. By applying virtual reality technology, it is possible to offer a greater learning experience for the learners. A VR-based wiring learning platform (VWLP), in this study, is proposed, which targets at offering a resource of assisted learning regarding the electrical equipment. The result of the study reveals that the VWLP constructed in this research can promote learning effectiveness in electrical engineering, especially in the area of wiring skills, and the blended learning mode (a mix of both conventional instructor-led practice activities and VR-based learning platform) enhances the learning effect. Besides this, the result shows that VWLP has a significantly positive effect regarding participants' learning cognition and motivation. By communicating with the virtual objects in the VR environment, the participants can demonstrate a promoted comprehension of the training equipment.

In this paper, a collaborative strategy based on the CDIO and CT is proposed for solving complex STEM problems in system modeling and simulation with a general framework, in which the CDIO is about “how to do,” CT is about “how to think,” and the project means “what to do.” As an illustration, the problem of solving the period of mathematical pendulum is discussed in detail. The most challenging task involved in the problem is to compute the complete elliptic integral of the first kind (CEI-1). In the philosophy of STEM education, all problems have more than one solution. For computing the CEI-1, four methods are discussed with a top-down strategy, which includes the infinite series method, arithmetic-geometric mean method, Gauss–Chebyshev method, and Gauss-Legendre method. The algorithms involved can be utilized for R & D projects of interest and be reused according to the requirements encountered.
