对现代化教学技术在音乐教学中唯上的批判——兼论教师在音乐教学中的核心作用

在目前的音乐教育课程改革过程中,存在着对现代化教学技术手段的运用“唯上”的误区,如何走出这一误区?广大音乐教师应该有如下的意识:现代化教育技术的运用并不是一节有效音乐课实施的关键所在,音乐教育也不是只有运用了现代化教育技术才能有所作为,而新课程改革的重点更不是落在对现代化教育技术手段的运用上,音乐教师的教学艺术才是成就一堂高质量音乐课的关键因素。

Analysis on Subtitle Translation in Forrest Gump

Subtitle translation industry requires the translator to understand that culture and master the translation skills. This subtitle translator can better and more easier to understand. Of course the subtitle translation must have profound understanding about culture. However, in the process of translating, sometimes even a word, also can’t just straightforward translated, so the translation skills is especially important in words mainly through the processing of the use of the techniques, including the add or remove meaning, double negative, digital processing, literal translation, the understanding of the culture in the subtitle translation, and subtitle translation reflect some of the features, and restrictions, including time space restrictions. Through the literature retrieval, analysis and understanding of the principles of subtitle translator and characteristics of the system, it comes the conclusion, that the language is affected by cultural influence and restriction, and colleagues culture industry affects the development of language.

植物叶片中叶绿素提取方法的比较研究

利用12种植物材料,应用分光光度法对分别以丙酮和乙醇作为提取剂,并同时各采用研磨与浸泡两种方法的叶绿素含量测定值进行比较研究.结果显示,4种方法测定的植物叶片叶绿素含量均具有一定的相关性,其中,乙醇浸泡法与乙醇研磨法的相关程度最高.且用乙醇作为提取剂测定植物叶片叶绿素含量比较稳定,尤其用乙醇浸泡法测定的人为误差相对较小.     

建立医学领域研究型博士学位评价标准的探讨——应用德尔菲法的尝试

医学领域研究型博士学位评价是对博士生经过3～5年学习之后形成的最终学习成果进行价值判断。为了探究医学领域研究型博士学位评价标准,我们采用德尔菲（Delphi）法,对22名专家进行两轮咨询。研究结果初步确立了医学领域研究型博士学位评价体系,包含4大要素、25项评价指标。本研究不仅为社会评价医学领域研究型博士学位提供统一的参考标准和导向,还为高校授予医学领域研究型博士学位提供一套实用的工具。     

论新形势下地方师范院校实验技术队伍建设——以喀什师范学院为例

基于语言符号象似性特征的科技新词翻译

通过对语言符号的任意性和象似性的特征进行分析，指出在创造科技新词时，语言符号的象似性使新词更有理据。因此，在翻译时以语言符号的任意性和象似性的辨证观为基础，从象似性的角度考虑英汉语的符号对等是切实可行的。     

Evaluating a technology supported interactive response system during the laboratory section of a histology course

Monitoring of student learning through systematic formative assessment is important for adjusting pedagogical strategies. However, traditional formative assessments, such as quizzes and written assignments, may not be sufficiently timely for making adjustments to a learning process. Technology supported formative assessment tools assess student knowledge, allow for immediate feedback, facilitate classroom dialogues, and have the potential to modify student learning strategies. As an attempt to integrate technology supported formative assessment in the laboratory section of an upper‐level histology course, the interactive application Learning Catalytics^TM, a cloud‐based assessment system, was used. This study conducted during the 2015 Histology courses at Cornell University concluded that this application is helpful for identifying student misconceptions “on‐the‐go,” engaging otherwise marginalized students, and forming a new communication venue between students and instructors. There was no overall difference between grades from topics that used the application and grades from those that did not, and students reported that it only slightly helped improve their understanding of the topic (3.8 ± 0.99 on a five‐point Likert scale). However, they highly recommended using it (4.2 ± 0.71). The major limitation was regarding the image display and graphical resolution of this application. Even though students embrace the use of technology, 39% reported benefits of having the traditional light microscope available. This cohort of students led instructors to conclude that the newest tools are not always better, but rather can complement traditional instruction methods.
