西部新建院校非英语专业学生口语交际能力培养初探

我国西部地区新建高等院校中非英语专业学生大多缺乏英语交流环境,口语交际能力普遍偏弱,可通过在课堂教学和课外活动中创设良好的语言环境来提高学生的口语交际能力。     

新课程理念下物理学史再认识

在新课程理念下物理学史与以往相比具有更多的教育功能，因此有必要对物理学史进行再认识，从克服传统物理课程弊端的角度来讲，需要将物理学史运用到物理教学中，而教育重演论为物理学史的应用提供了直接的理论依据。在新课程理念下将物理学史融入物理教学中，可以激发学生的兴趣，有利于学生的“终身学习”；帮助学生理解物理规律，提高问题解决的能力；提高学生的整体科学素养；发挥物理课的德育功能并促进学生的社会性发展等。可以说，物理学史在教学中是对知识与技能，过程与方法，情感、态度与价值观三维目标的有效整合。教师应更新观念；克服三个不利倾向：重视近、现代物理的发展；在教学上灵活处理。     

Conceptual change through vicarious learning in an authentic physics setting

Recent research on principles of best practice for designing effective multimedia instruction has rarely taken into account students’ alternative conceptions, which are known to strongly influence learning. The goal of this study was to determine how well students of quantum mechanics could learn ‘vicariously’ by watching a student-tutor dialogue based on alternative conceptions. Two video treatments were created to summarize key aspects of quantum tunneling, a fundamental quantum mechanical phenomenon. One video depicted a student-tutor dialogue, incorporating many of the common alternative conceptions on the topic, and resolving inconsistencies in reasoning through discussion. The other presented the same correct physics material in an expository style without alternative conceptions. Second year physics students were randomly assigned to one of the two treatments and were tested before and after watching the video during a lecture. Results show a statistically significant (p < .01) advantage for the learners in the dialogue treatment (d = 0.71). Follow-up interviews of students yielded insight into the affective and cognitive benefits of the dialogue video.

Metacognitive activity in the physics student laboratory: is increased metacognition necessarily better?

In this study natural-in-action metacognitive activity during the student laboratory in university physics is explored, with an aim towards quantifying the amount of metacognition used by the students. The study investigates whether quantifying natural-in-action metacognition is possible and valuable for examining teaching and learning in these contexts. Video recordings of student groups working during three types of introductory physics laboratories were transcribed and then coded using a coding scheme developed from related research on mathematical problem solving. This scheme identifies a group’s general behaviour and metacognitive activity. The study recognizes that reliably identifying metacognition is challenging, and steps are taken to improve reliability. Results suggest that a greater amount of metacognition does not appear to improve students’ success in the laboratory—what appears to matter is whether the metacognition causes students to change behaviour. This study indicates that it is important to consider the outcome of metacognition, not just the amount.

探析英语专业视听说教学中文化导入的重要性

语言从深层次反映一个民族的文化特点,要学好一个民族的语言,必须学习该民族的文化。因此,在英语视听说教学中,教师既要重视语言知识的传授,又要注重文化知识的传授。从语言与文化的关系、英语视听说教学导入文化的重要性等方面作一探析,同时给出了一些提高学生跨文化意识的对策。
