二语词汇习得的心理表征对英语学习词典编纂的启示

词汇习得是二语习得的重要环节,是二语习得研究的中心。二语词汇的心理表征和发展具有阶段性特点,针对各个阶段的形成机制与特点,充分发掘学习词典的教学功能,使英语学习词典在宏观与微观结构的设置上更符合二语学习者的习得规律,丰富其二语词汇知识,提高词汇运用能力,促进词汇能力的全面发展。     

透视学习词典中观结构的语义认知观

构建学习词典的中观结构可以借鉴认知语言学中对语义认知的一些观点,以学习者词汇认知的心理表征为依据,建立合理的词典结构体系,再现自然词汇语义网络,帮助学习者形成有效的词汇推理和生成能力。     

Science teachers' pedagogical content knowledge development during enactment of socioscientific curriculum materials

The purpose of this study is to provide insight into short-term professionalization of teachers regarding teaching socioscientific issues (SSI). The study aimed to capture the development of science teachers' pedagogical content knowledge (PCK) for SSI teaching by enacting specially designed SSI curriculum materials. The study also explores indicators of stronger and weaker development of PCK for SSI teaching. Thirty teachers from four countries (Cyprus, Israel, Norway, and Spain) used one module (30–60 min lesson) of SSI materials. The data were collected through: (a) lesson preparation form (PCK-before), (b) lesson reflection form (PCK-after), (c) lesson observation table (PCK-in-action). The data analysis was based on the PCK model of Magnusson, Krajcik, and Borko (1999). Strong development of PCK for SSI teaching includes “Strong interconnections between the PCK components,” “Understanding of students' difficulties in SSI learning,” “Suggesting appropriate instructional strategies,” and “Focusing equally on science content and SSI skills.” Our findings point to the importance of these aspects of PCK development for SSI teaching. We argue that when professional development programs and curriculum materials focus on developing these aspects, they will contribute to strong PCK development for SSI teaching. The findings regarding the development in the components of PCK for SSI provide compelling evidence that science teachers can develop aspects of their PCK for SSI with the use of a single module. Most of the teachers developed their knowledge about students' understanding of science and instructional strategies. The recognition of student difficulties made the teacher consider specific teaching strategies which are in line with the learning objectives. There is an evident link between the development of PCK in instructional strategies and students' understanding of science for SSI teaching.     

Developing a Training Course for Undergraduate Teaching Assistants

An undergraduate teaching assistant (UTA) training course was developed using existing best practices and Bloom’s taxonomy of educational objectives as a framework. Course goals included developing assistants’ content knowledge, procedural knowledge, and metacognition regarding teaching. Across three semesters, UTAs’ (N?=?68) pre- and post-test responses showed significant increases in their teaching-related knowledge, confidence in their skills, consideration of a teaching-related career, and perceived benefits of being a UTA. The course provides an efficient method by which assistants learn to support students and faculty in a range of undergraduate courses, serving as a potential model for other teaching assistantship programs.     

英语词汇的文化内涵意义

英语表达不能只做到准确,得体、贴切更重要,掌握词汇的文化内涵对语言表达得体有重要作用。通过思维模式、价值观念和生活习俗三个层面与汉语词汇的对比,展示了英语词汇蕴含的丰富文化内涵。     

教师关心、自我调节学习与学业成就的关系

以227名初中生为被试，考察了他们心目中“关心型”教师的主要特征，以及知觉到的教师关心、自我调节学习与学业成就的关系。结果发现：初中生认为一个关心学生的教师应该在有效教学、民主管理、学习指导和生活关心几个方面有所表现；初中生知觉到的教师关心、学习策略、效能感与学业成就的相关显，其中自我效能感是影响学业成就的重要因素。     

教育学立场：教育学走出困境的路径

教育学面临系列危机:教育学学科独立性危机、教育学理论功能危机、教育学话语危机以及教育学研究中人的缺场导致的“无人”危机;研究和明确教育学的立场是教育学走出困境的根本路径。     

Collaborative learning practices: teacher and student perceived obstacles to effective student collaboration

While the educational literature mentions several obstacles affecting the effectiveness of collaborative learning (CL), they have often been investigated through the perceptions of only one actor, either teachers or students. Therefore, some sources of obstacles that teachers and students encounter may not have been revealed. In this study, 19 teachers and 23 students in different disciplines at a pre-service teacher education faculty at a university in Vietnam were interviewed. In total, 47% of the teachers taught science subjects and 53% taught social subjects; 35% of the students majored in science subjects, 57% in social subjects, and 8% in primary education. With regard to study cohorts, 22% of the students were in the first and second year while 78% were in the third and fourth year of their four-year bachelor’s programme. These programmes produce qualified teachers for primary and secondary schools nationwide. Based on grounded theory analysis, four common obstacles to collaboration were identified: students’ lack of collaborative skills, free-riding, competence status, and friendship. Furthermore, the results showed three interrelated antecedents that contribute to these obstacles. Central to the antecedents is the strong focus of the teachers on the cognitive aspects of CL, which led the participating teachers to neglect the collaborative aspects of CL. These antecedents were demonstrated in the ways teachers set CL goals, provided instruction, and assessed student collaboration. This study may be useful for educators, designers, and researchers to foster the quality of student collaboration.     

基于TPACK理论的学科教育技术课程研究及启示——以英属哥伦比亚大学“运用技术教数学与科学”课程为例

学科教育技术课程是培养教师实施信息技术与学科教学深度融合能力的重要载体.为了探讨如何建设深入学科的教育技术课程,采用内容分析和深度访谈等方法研究了英属哥伦比亚大学的一门在线教育硕士项目课程--"运用技术教数学与科学".研究发现:该课程以TPACK理论和有意使用技术的教学思维框架为指导,其课程特色是以融合为导向,以问题为纽带,以探究为核心,以作品为中心,以协作为形式.这充分体现了整合性STEM教育的5个关键特征:STEM多学科融合,基于问题的学习,基于探究的学习,基于设计的学习,基于协作的学习.研究启示:(1)以学科教育技术为依托培养教师的信息化教学能力;(2)以学科交叉融合为导向培养教师的跨学科教学能力;(3)以信息技术支持的跨学科教育为切入点培养社会需要的创新型人才.     

Mathematics Teaching as a Deliberate Practice: An Investigation of Elementary Pre-service Teachers' Reflective Thinking During Student Teaching

In this case study I examine the reflectivepractices of two elementary pre-serviceteachers during their student teachinginternship. I extend current views ofreflective practice to create a framework for a`deliberate practitioner'. With this framework,I investigate the pre-service teachers'thinking with regard to reflective processesand how they use their pedagogical contentknowledge in their practices. My findingsindicate that the pre-service teachers usetheir pedagogical content knowledge inanticipating problematic events, and inreflecting on problematic events ininstruction. However, limits in pedagogicalcontent knowledge and lack of confidence impedethe pre-service teachers' reflection while inthe act of teaching. They were more likely toreflect on their practices outside of the actof teaching. Implications for teacher educatorsand pre-service teachers are discussed.
