BE学习需求实证研究

ESP是一种教学方式,把ESP需求分析理论应用到商务英语教学上,能更系统地发现商务英语学习者对教学的需求。调查结果显示,教学者需进一步加强商务专业知识,教材设计应更贴近实际商务环境。同时,学习者需要符合商务英语教学规律的教学方法。     

The function and integration of components of pedagogical content knowledge (PCK) in classroom teaching: a case study of business English teachers

While pedagogical content knowledge (PCK) has been studied across a wide range of research areas, including science, language teaching and mathematics, there is limited research on the role of PCK in business English (BE) teaching, an important teaching area of English for Specific Purposes. Informed by the conceptual framework of the PCK model for BE teaching, this study examined how four BE teachers integrated the PCK components in their actual classroom teaching in the English as a Foreign Language (EFL) context in China. The analysis of multiple sources of data including classroom observation, semi-structured interviews and teaching materials, identified the different patterns and ways in which the four PCK components (i.e. knowledge of the purposes of BE teaching, knowledge of instructional strategies for BE teaching, knowledge of students’ understanding of BE, and knowledge of the BE curriculum) functioned and were integrated in BE teaching. Implications for BE teaching practice and suggestions for future research on PCK in BE teaching are presented in the paper.     

Cell BE高性能计算实验平台设计与实现

Cell BE为一个异构多核并行处理架构,具有超高速通信能力,能够有效地提供超级计算机的性能。在分析与研究Cell BE的硬件架构、并行编程环境与模型的基础上,选取PS3为主机,构建一个CellBE高性能计算实验平台。通过选取相关的硬件设备,在构建好硬件平台的基础上,构建系统与软件平台。通过在实验平台上运行高性能计算应用程序,来对平台进行实验测试。以求解多体问题的计算为平台实验应用程序,将四叉树计算初始化过程算法在Cell BE实验平台上实现,并进行运行测试。在不同的粒子数实验规模下的计算时间结果表明,在Cell BE平台上获得了较高的对CPU的加速效果。
