面向学习者的数学问题解决教学设计——信息技术与数学课程整合的视角

问题解决能力是数学教学的核心目标。数学教学是基于“问题解决学习”的教学,数学教学设计应当是问题式教学与问题式学习的对立统一关系的设计。“问题解决教学”重视从宏观上、整体上让学生把握数学学科的基本结构,倡导“整合认知,框架推进”,围绕“主题”进行教学设计,各个教学环节构成了一个完整的知识建构过程,在每一环节,各种教学模式可灵活选用。     

纹理谱直方图与潜在语义标引在图像检索中的应用

提出一种新的描述局域像素灰度变化的纹理谱方法,并将该方法抽取出的纹理谱直方图特征用于图像检索。实验表明该特征计算简单,检索结果较好,是一种适于图像检索的底层特征。同时将应用于文本检索领域的潜在语义标引方法用于图像检索,并提出了一种计算近似矩阵秩的方法。实验结果显示使用该方法可以分析图像中存在的隐含语义结构,并提高检索效率。

Using inquiry-based instruction to encourage teachers' historical thinking at historic sites

This study explores the use of inquiry-based instruction for constructing historical understanding in historic site-based teacher professional development programs. In an historic site-based professional development workshop, fifteen teachers of grades 5 through 12 engaged in guided inquiry with documents drawn from said historic site. Participants showed significantly increased curiosity about the site and use of problem-solving strategies in interactions with the site and staff, but no improvement in other elements related to historical thinking at historic sites. Improvements correlated to neither length of teaching experience nor testing group characteristics, indicating broad applicability for improving historic site-based professional development programs.     

Open plan

This study reports on an investigation into the impact of strategy-based English language instruction (SBELI) on the language proficiency of gifted learners. The participants were students who were identified as gifted and thus received additional out-of-school training for a few days a week in Adana Science and Arts Centre. Their ages ranged from 10 to 13. One experimental group (n = 17) and one control group (n = 17) were designed to explore the possible English performance differences between the learners who were exposed to SBELI, which included 11 language-learning strategies for eight weeks, and those who were not. Data were collected through proficiency exams, written accounts of participants in the experimental group, think-aloud protocols and an open-ended questionnaire. The findings obtained revealed that SBELI produced a positive impact on the language proficiency of the gifted students and enabled them to enhance their already established attitude to make their language learning quick, easy, effective and enjoyable.     

The Sources of Science Teaching Self-efficacy among Elementary School Teachers: A mediational model approach

This study aimed to investigate the factors accounting for science teaching self-efficacy and to examine the relationships among Taiwanese teachers’ science teaching self-efficacy, teaching and learning conceptions, technological–pedagogical content knowledge for the Internet (TPACK-I), and attitudes toward Internet-based instruction (Attitudes) using a mediational model approach. A total of 233 science teachers from 41 elementary schools in Taiwan were invited to take part in the study. After ensuring the validity and reliability of each questionnaire, the results indicated that each measure had satisfactory validity and reliability. Furthermore, through mediational models, the results revealed that TPACK-I and Attitudes mediated the relationship between teaching and learning conceptions and science teaching self-efficacy, suggesting that (1) knowledge of and attitudes toward Internet-based instruction (KATII) mediated the positive relationship between constructivist conceptions of teaching and learning and outcome expectancy, and that (2) KATII mediated the negative correlations between traditional conceptions of teaching and learning and teaching efficacy.     

高校图书馆新生培训效果调查及培训模式创新——以中山大学东校区图书馆为例

采用问卷调查法对中山大学东校区图书馆新生培训效果进行调查,发现其中存在有限的培训时间与不断增长的培训内容之间的矛盾、不断增长的新生人数与有限的培训资源之间的矛盾、培训针对性不强等问题亟待解决。在图书馆现有培训资源的基础上,提出新生培训前开展自学自测、采用体验式学习模式和针对性电子资源现场操作演示相结合的新型培训模式,将传统新生培训与网络技术紧密结合在一起,适应新形势下新生培训工作的需求。
