从中西文化差异看狄金森与李清照的爱情诗

爱情是狄金森和李清照创作的共同主题。但在这一共同主题下,她们的爱情诗在内容和表述方法上又有所不同。狄金森的爱情诗,常写到在死后与爱人作永久的结合。而李清照的作品表现的多是深闺少妇思念远方丈夫的离情别绪。再者,由于她们生活在完全不同的文化背景之下,所以表达爱情的方式也不同。狄金森大胆直率,而李清照委婉含蓄。     

艺术设计专业聋哑学生的素描教学探究

在以往的教学模式中,造型的训练只是将素描纯粹化,通过学生对造型的自主把控,理解其中与相关设计专业的共性点,加以培养。笔者认为普通造型基础课的素描培训与高职教育中艺术设计的素描培训还是存在一定的差异性,特别是在特教教学中,对于有听觉障碍的聋哑学生这一特殊群体,基于有效教学这一出发点,更是要将素描教学与相关实用艺术设计专业的共性把握准确,在学习的阶段性和实践性中加以分析,切实切入相关艺术设计专业的造型训练方向,才能掌握学情,完成特殊艺术教学的培养目标。     

Learning from Chemical Visualizations: Comparing generation and selection

Dynamic visualizations can make unseen phenomena such as chemical reactions visible but students need guidance to benefit from them. This study explores the value of generating drawings versus selecting among alternatives to guide students to learn chemical reactions from a dynamic visualization of hydrogen combustion as part of an online inquiry unit. In prior research, generation has been more successful than selection in helping students distinguish among ideas to learn complex topics. However, selecting among perplexing alternatives may motivate learners to distinguish among ideas they might otherwise neglect. To test the value of selection for helping students distinguish ideas, this study contrasted complex selection (involving normative as well as non-normative ideas identified in prior research) from typical selection (involving images from the visualization). Results showed that all conditions improved student understanding and that typical selection was less effective than generation while complex selection was as successful as generation. In both generation and complex selection students revisited the visualization while learning, whereas revisiting was rare in typical selection. These results support the idea that distinguishing among common non-normative ideas is more valuable than distinguishing among images from the visualization. In addition, for students with low prior knowledge, both generation and complex selection had some advantages. Overall, the results suggest that students learning from complex visualizations could benefit from a combination of complex selection and generation.

利用古地磁数据对印度板块运动规律的研究

利用古地磁数据,结合极射赤平投影方法,开展确定板块运动方法的研究。将其应用到印度板块137Ma至今运动规律的研究中,确定印度板块的运动轨迹为:印度板块于137Ma~65Ma向北微偏西向运动;65Ma~35Ma向北偏西30°方向运动;35Ma至今向北偏东60°方向运动。可将该方法进一步应用到研究其他板块的运动规律中。     

基于STM32的手写绘图板的设计与实现

本文提出了由微控制器STM32为主控制核心,利用普通的PCB覆铜板设计和制作低功耗手写绘图输入设备,通过表笔与覆铜板接触进行电压信号采集,然后将采集到的信号经高精度仪表放大器AD620放大调理后再通过24位高精度AD转换器ADS1256转换为单片机能够处理的数字信号,最后在LCD屏上显示对应接触点的坐标位置。
