摘要： Given the importance of broadening participation in computer science classes, this paper investigates the use of participatory design as a means to develop a culturally relevant computer science curriculum. The Scratch Encore curriculum is designed for 5th–8th grade (10–14 years old) learners and seeks to present computer science concepts in a relevant way that allows for both teacher and student flexibility in the lesson themes and student created project content. To create the curriculum, we ran a series of participatory design sessions with various educational stakeholders including students, teachers, administrators, and parents. In this article, we explore the ways that ideas from the participatory design sessions shaped the final curriculum. Specifically, we focus on the use of participatory design as a context for culturally relevant idea generation and the various ways these ideas can be incorporated into instructional materials. We present these methods of integration as potential means through which others seeking to create culturally relevant materials can utilize participatory design and stakeholder voices within their design process. © 2021 Elsevier B.V.

摘要： Speech emotion recognition (SER) is becoming the main human-computer interaction logic for autonomous vehicles in the next generation of intelligent transportation systems (ITSs). It can improve not only the safety of autonomous vehicles but also the personalized in-vehicle experience. However, current vehicle-mounted SER systems still suffer from two major shortcomings. One is the insufficient service capacity of the vehicle communication network, which is unable to meet the SER needs of autonomous vehicles in next-generation ITSs in terms of the data transmission rate, power consumption, and latency. Second, the accuracy of SER is poor, and it cannot provide sufficient interactivity and personalization between users and vehicles. To address these issues, we propose an SER-enhanced traffic efficiency solution for autonomous vehicles in a 5G-enabled space-air-ground integrated network (SAGIN)-based ITS. First, we convert the vehicle speech information data into spectrograms and input them into an AlexNet network model to obtain the high-level features of the vehicle speech acoustic model. At the same time, we convert the vehicle speech information data into text information and input it into the Bidirectional Encoder Representations from Transformers (BERT) model to obtain the high-level features of the corresponding text model. Finally, these two sets of high-level features are cascaded together to obtain fused features, which are sent to a softmax classifier for emotion matching and classification. Experiments show that the proposed solution can improve not only the SAGIN's service capabilities, resulting in a large capacity, high bandwidth, ultralow latency, and high reliability, but also the accuracy of vehicle SER as well as the performance, practicality, and user experience of the ITS.

摘要： States increasingly are adopting computer science standards to help students develop coding and computational thinking skills. In an effort to support teachers in introducing computer science content to their students with high-incidence disabilities, a new model, computer science integration planning plus universal design for learning (CSIP+) offers ways to integrate computational thinking and coding into content area instruction. This column presents an example of how a teacher might implement the CSIP+ model when designing instruction accessible to all learners. Guiding questions to support teachers at each phase of the planning cycle are provided.

关键词： Distributed computer systems  

摘要： With the advent of distributed computing, the need for frameworks that facilitate its programming and management has also appeared. These tools have typically been used to support the research on application areas that require them. This poses good initial conditions for translational computer science (TCS), although this does not always occur. This article describes our experience with the PyCOMPSs project, a programming model for distributed computing. While it is a research instrument for our team, it has also been applied in multiple real use cases under the umbrella of European Funded projects, or as part of internal projects between various departments at the Barcelona Supercomputing Center. This article illustrates how the authors have engaged in TCS as an underlying research methodology, collecting experiences from three European projects.

摘要： The adoption of computational thinking in the classroom has been growing in the last years. Its use needs to be supported by the correct digital technologies and teaching methods, and for this, is required, capable teachers. This work aims to understand how computational thinking is addressed by Computer Science Teacher Education courses in Brazil, and which digital technologies and teaching methods are used to foster it. A survey was conducted, and a roadmap was built. Main obtained results are: Common and accessible technologies, used in everyday life, can help promote computational thinking;Researchers and teachers can explore the list of technologies surveyed and categorized to promote computational thinking;Teachers can analyze the teaching methods used and understand how these methods are applied in the teaching process;The teachers and researchers can use and explore the best technologies identified in the paper, to foster each computational thinking characteristic. Moreover, it is essential to enhance the knowledge about computational thinking, to apply the correct digital technologies and teaching methods in its promotion.
