摘要： As computer science grows in popularity, more faculty are needed to staff computer science courses. Approval for full-time tenure-track faculty and permanent instructor positions can lag student enrollment demands. One common strategy to meet student enrollment needs is to expand sections sizes. Another strategy is to staff courses with adjunct faculty. This paper describes the experiences of alumni serving as adjunct faculty members to teach introductory computer science labs. These alumni learned introductory programming by completing these labs as students, and then served as role models for computer science majors by providing professional and career advice. The paper provides an overview of the introductory computing labs, "professions" talks the alumni gave each week, and perspectives from the alumni after teaching the labs.

摘要： Quantization has been proven to be a vital method for improving the inference efficiency of deep neural networks (DNNs). However, it is still challenging to strike a good balance between accuracy and efficiency while quantizing DNN weights or activation values from high-precision formats to their quantized counterparts. We propose a new method called elastic significant bit quantization (ESB) that controls the number of significant bits of quantized values to obtain better inference accuracy with fewer resources. We design a unified mathematical formula to constrain the quantized values of the ESB with a flexible number of significant bits. We also introduce a distribution difference aligner (DDA) to quantitatively align the distributions between the full-precision weight or activation values and quantized values. Consequently, ESB is suitable for various bell-shaped distributions of weights and activation of DNNs, thus maintaining a high inference accuracy. Benefitting from fewer significant bits of quantized values, ESB can reduce the multiplication complexity. We implement ESB as an accelerator and quantitatively evaluate its efficiency on FPGAs. Extensive experimental results illustrate that ESB quantization consistently outperforms state-of-the-art methods and achieves average accuracy improvements of 4.78%, 1.92%, and 3.56% over AlexNet, ResNet18, and MobileNetV2, respectively. Furthermore, ESB as an accelerator can achieve 10.95 GOPS peak performance of 1k LUTs without DSPs on the Xilinx ZCU102 FPGA platform. Compared with CPU, GPU, and state-of-the-art accelerators on FPGAs, the ESB accelerator can improve the energy efficiency by up to 65x, 11x, and 26x, respectively.

摘要： In this paper we describe techniques intentionally designed to promote inclusivity and equity in an introduction to computer science course. We describe approaches for using randomly-drawn name cards as an alternative to cold-calling students for participation in class. We also discuss using an online polling technique that utilizes components of the Peer Instruction pedagogy to solicit low-stakes individual contributions. In each case, we motivate the "best practices" we have experienced and propose methods for making computer science classrooms more inclusive and equitable.

摘要： The COVID-19 pandemic provided motivation to shift course modalities and assignments to online experiences as many universities suddenly required all course instruction to move online. In response to the continuing global health crisis, many universities offered the majority of their courses with online modality for over twelve months following the beginning of the pandemic. In addition to classroom changes, students and faculty faced health, economic, and social stresses not previously experienced. We compare survey data of student perceptions of course experiences during their online experiences and after returning to a traditional in-person course environment. We identify student perceptions of tools that contributed to their success during online courses as well as challenges faced. Our survey data provides a window into how students felt during the online course experience and after returning to in-person classes during this unique period.

摘要： This paper presents a course model for changing the mindset of students as future leaders in technology-based fields. Research shows that entrepreneurial education within engineering is an important facet of degree programs; however there are not as many models incorporating this mindset focus into computer science education. The authors describe a "Business and Technology Ventures" course that is required for computer science majors. The topics, outline, and projects are described with potential adaptions so that others can adopt or adapt components of this course model. One of the specific benefits of this approach is that it increases job readiness by enhancing non-technical skills. This course has been offered three times, and the instructors are satisfied with students' achievement of the learning objectives and students' achievements.

摘要： This paper describes a collaborative project that was conducted to promote the Computer Science (CS) and Computation Thinking (CT) Education among Education Faculties. 9 Education Faculties from three local and regional schools participated in a learning experience designed to address the K-12 Computer Science Framework[1] and Maryland's K-12 Computer Science Standards. The collaboration was designed to develop CS/CT knowledge, understanding, skills and application among Education Faculties who work to prepare teachers. The plan is to build the capacity of faculty to integrate CS and CT into several preservice courses as well as build into the coursework sequence meaningful experiences that expose future teachers to CS and CT knowledge and skills so that they can in turn incorporate these into their own lesson plans. Project evaluation included formative and summative assessments to examine changes in content and pedagogical knowledge. Phase one feedback from the participants shows positive result.

摘要： Some specific services for Internet of Things, such as real-time map and providing local weather information, depend strongly on geographical time and location. We refer to the data for such service as spatio-temporal data (STD). When STD is used in a query response system similar to conventional Internet services, users not only need to acquire data actively as required, they must also have functions for retrieving data available STD. Therefore, we propose an STD retention system that uses vehicles as information hubs (InfoHubs) for disseminating and retaining the data in a specific area. In our system, InfoHubs diffuse, maintain, and advertise STD over places and times where the STD are strongly dependent, thereby allowing users to receive such data passively within the specific area. Additionally, because STD are associated with a particular space, the system can reduce search costs. We also propose an adaptive transmission control method that each vehicle effectively operates its wireless resources autonomously and STD are retained and distributed efficiently. Finally, we evaluated our proposed method using simulations and clarified that our proposed system is capable of achieving a coverage rate of nearly 100 percent for STD while reducing the number of data transmissions compared to existing systems.

摘要： The article deals with the problem of creating conditions for the formation of metasubject educational results of primary schoolchildren, including communicative and regulatory universal educational actions, in the context of the digitalization of education. The analysis of scientific literature has shown that after the transition of the initial stage of education to the second generation standard in 2010, this problem still occurs. The article describes the possibilities of implementing joint network activities of elementary school students within the framework of the academic subject “informatics” in a specially organized digital educational environment that promotes the formation of universal educational actions by gradually increasing the complexity of network communication through the joint performance of network tasks based on a four-level model of network interaction. Positive influence of the inclusion of network interaction in lesson activities in elementary school on students’ readiness to carry out training in a remote mode has been substantiated.
