A project funded by the National Science Foundation, Computer Science Integrated with Mathematics in Middle Schools (CSIMMS) (DRL-1640039), brought middle-school mathematics teachers together with university computer science (CS) faculty and STEM education faculty to design, develop, and test curriculum modules in which CS is integrated into instruction for middle-school general-mathematics courses. The project developed integrated math/CS curriculum modules (for grades 6, 7, and 8), complete with student tasks and teacher materials to guide classroom implementation. Across the project, sixteen teachers from four middle schools representing different school contexts (both urban and suburban, serving students from a range of demographic and socioeconomic backgrounds) participated as members of the design team and trial testers of the math/CS modules. All modules underwent multiple years of testing and refinement, with extensive input from the teachers who co-designed and implemented them. Approximately 50-100 middle-school students participated in the classes of those who taught each year. The modules in this volume feature a range of models for integrating mathematics and computer science at the 6th and 7th grade levels. All modules foreground the teaching of grade-level mathematics content, with computer science functioning to motivate and/or reinforce these ideas.

In this mixed-method study, we investigated the impact and design of a multiuser, virtual reality (VR) supported teaching simulation, in comparison with live classroom teaching simulation, on the participatory training of teaching and the teaching knowledge development of student instructors. A total of 40 university teaching assistants participated in a 4-h training session in which they were randomly assigned to a VR simulation or a live classroom simulation condition. The study indicated that the VR simulation better promoted the lab-teaching knowledge development than the live simulation, whereas the latter better fostered class-teaching knowledge development. All participants reported higher teaching self-efficacy after the training. The qualitative data indicated that domain-specific challenges and authentic environmental prompting in the VR simulation fostered both experiential and vicarious learning of teaching. However, VR participants lacked mutual engagement in collaborative role-playing. The study findings suggest that VR-based simulation can supplement and work as an alternative to the live classroom simulation to host participatory teaching development.

... T-UGAL [24] employs a subset of all possible VLB paths in UGAL that has a smaller average path length. Various machine learning-based routing schemes for Dragonfly were also proposed [5,19]. Q-adaptive [19] routing leverages multi-agent reinforcement learning (MARL) to train routers. ...

... Integration also offers opportunities to develop both CT and disciplinary knowledge and skills as well as critical thinking [26], [13], [8], [34]. The integration approach also provides an opportunity to reach students that would not be likely to enroll in a computer science course due to preference [7], [36], [37] and/or access or availability to such courses at their school (e.g., in ability to add more classes [14]). Issues of access and availability have been well documented at the high school level [4] and decrease as we move into the elementary and middle grades [10], [35], [36]. ...

... VR simulations can effectively immerse preservice teachers in a contextualized learning environment, enabling them to apply their teaching knowledge to solve authentic problems (Ke et al., 2021). However, some researchers have identified limitations in VR simulations, such as low realism and limited interaction with non-player characters (Correia et al., 2016;Lovreglio et al., 2022) as well as difficulties in accurately reflecting the complexity and unpredictability inherent in real-world problems (Schwarze et al., 2019;Wang, 2012), which could potentially undermine the learning outcomes of VR simulations. ...

... VR simulation has been used for teacher learning with affordances such as virtual role-play [26], practice-based learning [21], and broader opportunity for simulated teaching practicum [13]. VR simulation has been found to be valuable in improving student teachers' noticing of students' in-class behaviors as well as student teachers' exercise of domain specific knowledge and pedagogical knowledge in teaching activities [21]. ...

... This makes the current online courses have a single way of presenting teaching information and no basis for the design of the virtual teacher's visual appearance, which brings about problems such as uneven quality of the courses and unsatisfactory learning effect of the learners [13][14][15][16]. Constructing and optimising the virtual teacher system, embedding it organically into the English intelligent teaching platform, and combining English education in colleges and universities with new media intelligent education, make English education intelligent and effectively supported [17][18]. ...

... This approach allows one to encrypt MPI communication without modifying the MPI library. The second option is to naively incorporate encryption to the MPI library by encrypting the whole message at the sender side, transmitting the entire ciphertext, and decrypting the ciphertext at the receiving side [1]. Fig. 1 illustrates the performance of the unencrypted baseline, IPSec, and our library CryptMPI on a 10 Gbps Ethernet network. ...
