适应行为研究的新理论——社会性能力理论

随着智力落后儿童教育研究的发展,适应行为的研究已经成为研究 者们关注的一个重要问题。但是,长期以来有关适应行为的研究一直存在争 论。本文将介绍美国心理学家格林斯潘的一个适应行为研究的新理论—— 社会性能力理论的内容、发展以及其的意义。以期对我国智力落后儿童的适 应行为研究有所借鉴。     

Bases of competence: an instrument for self and institutional assessment

The Bases of Competence model provides a general framework for learner‐centred skill development and programme‐focused outcomes assessment. Based on previous research, the Bases of Competence model describes 17 skills and four base competencies important to graduates to achieve high performance in the workplace. Taking this work from research to relevant educational application as a tool for student self‐assessment and institutional outcomes assessment is the focus of this paper. Results from a multi‐year, multi‐course assessment initiative indicate that students rate themselves stronger in the foundation base competencies of Communicating and Managing Self, and weaker in more complex competencies of Managing People and Tasks and Mobilising Innovation and Change. Comparisons of skill confidence within each base competence as well as between year, student level, gender and beginning versus end of semester are presented as well. These results are discussed and suggestions made for programme design.

移动机器人CartographerSLAM建图改进研究

移动机器人即时定位与建图（SLAM）技术研究越来越多,但移动机器人SLAM技术存在一些问题,如在构建地图中进行回环匹配时,由于数据信息相似或者数据采集模糊易造成回环出错,从而降低地图精度。对CartographerSLAM在回环检测时使用ScantoMap匹配出现特征点缺失问题进行改进,提出Map to Map策略。该方法利用子图间的匹配闭环检测,去掉连续帧之间的冗余数据,减少运算时间,提高精度。对改进算法结果进行实验对比,选取相关点计算误差作出折线图,可直观看出改进后的算法建图误差比改进前的误差小。

Willingness to Communicate in Intercultural Interactions between Chinese and Americans

This study investigated the differences in willingness to communicate (WTC) between Americans and Chinese living in China and the United States, and the factors affecting WTC between these two nationalities. A battery of questionnaires was administered to 47 American and 54 Chinese college students in China, and 51 American and 42 Chinese college students in the US. Overall Americans were found to be more willing to communicate with Chinese than were Chinese with Americans. Participants living abroad reported higher levels of WTC than those living in their home country. Among Chinese, WTC was positively related to self-perceived communication competence, language competence, immersion time and motivation being positively correlated and negatively associated with CA. Similar results were obtained from Americans, except that immersion time and language competence were not related to WTC.     

Can EFL Speakers Communicate in English-mediated Classes?: A Case of a Liberal Arts Class for Engineering Students in Korea

The purpose of this paper is twofold: (1) to explore what factors prevent English as a foreign language (EFL) students from participating in English-medium instruction classes; and (2) to examine how dialogic teaching techniques enhance students’ participation in classroom interaction. Utilizing the notions of “communicative competence” and “truncated repertoire,” we first investigated the barriers to communication in classrooms. We next examined how EFL speakers are able to communicate in English-medium instruction (EMI) classes. The findings suggest that when the instruction was designed to reduce cultural barriers and to facilitate authentic discussion, EFL students were able to participate in classroom interaction, and they perceived discussion as a way to learn an unfamiliar subject taught in English.     

基于GPS数据的立交桥识别及层次判断算法

卫星遥感图与城市路网配准后,可用于交通仿真和车辆态势显示。现代城市路网不包含立交桥层次信息,为真实模拟车辆在立交桥的行驶效果,提出了一种基于GPS数据识别立交桥并判断其上下关系的算法。该算法首先计算线段交点来识别立交桥,其次判断上下层是否连通来区分其类型,再将GPS轨迹数据与路网匹配,通过分析GPS高度数据的变化趋势来判断立交桥层次。最后在成都市路网上对算法的有效性进行了验证,实验结果表明,路网立交桥判定快捷,上下层关系区分正确。     

基于核心素养的高中地理教学策略

在高中新课改的背景下,地理核心素养已经成为地理学科教学的重要目标,对学生形成地理思维、具备地理观念、提升地理探究能力具有重要的意义。高中地理教师应当明确培养学生地理核心素养的基本教学目标,探索和应用高效的教学策略,以充分提升教学效率。
