The impact of learner characteristics on information utilization strategies, cognitive load experienced, and performance in hypermedia learning

Against the background of an adaptation of Cognitive Load Theory to learner-controlled settings we investigated the impact of learner characteristics on information utilization strategies, cognitive load, and learning outcomes in a hypermedia environment. Based on the data of 79 students, five clusters of students were identified according to their learner characteristics by means of a cluster analysis. Further analyses showed that learners with more favorable characteristics (i.e., higher prior knowledge, more complex epistemological beliefs, more positive attitudes towards mathematics, better cognitive and metacognitive strategy use) tended to show a more adaptive example utilization behavior, reported less cognitive load, and solved more problems correctly than learners with less favorable characteristics.

试析我国学校德育实效低下的内在原因

由于受到现代社会市场经济的冲击和新科技、"教育全球化"的影响,我国德育面临着严峻的挑战,学校德育更是步履维艰.本文认为,除了上述大环境的影响外,导致我国学校德育实效低下有五大基本原因,即教育理念的偏差,致使学校德育丧失地位;理论研究的误区,致使学校德育无所适从;教育教学的分离,致使学校德育残缺不全;方法途径的单调,致使学校德育功效甚微;管理体制的分治,致使学校德育步履维艰.     

Factorial Validity and Reliability of the Curricular Goals in Physical Education Questionnaire

This study aimed to examine the validity and reliability of an instrument designed to measure student perceptions of curricular goals in physical education, the Curricular Goals in Physical Education Questionnaire. Participants were 879 Finnish students from grades 7 to 9 (412 girls, 467 boys; mean age 13.81). An exploratory factor analysis was performed on Sample 1 (n = 287), revealing a four-factor solution and suggesting that factor structure be cross-validated with confirmatory factor analysis in Sample 2 (n = 592). Confirmatory factor analysis demonstrated an acceptable fit and supported the four-factor model. Tests for gender invariance supported configural, metric, and scalar invariance. Analyses of factor mean differences indicated that girls attributed more importance than boys to physical education’s health-related goals, social and emotional learning, and motor skill development. This study confirmed the validity of the Curricular Goals in Physical Education Questionnaire to assess student perspectives on curricular goals across gender. In order to improve factor structure the authors suggest the addition of an item measuring skill acquisition to future versions of the instrument.     

柔性制造与职业技术教育的对比分析

文章在分析柔性制造基本特征的基础之上,归纳提出了柔性制造的柔性特征.通过对柔性制造与职业技术教育的本质比较,论述了二者的可比性并概括了二者的类比要素.最后,文章对二者的各种柔性特征进行了比较分析,得出了柔性制造与现代职业技术教育的相似性结论,为进一步引入柔性制造系统理论来构建基于柔性制造的职业技术教育模式奠定了理论基础.     

"翻转课堂"在《仪器分析》教学中的应用

"翻转课堂",是指课上的教学活动和课下的学习活动相交换,将学习的决定权从教师转移给学生,可以很好的克服传统教育的不足之处。文章结合"测量富硒康中硒的含量-原子荧光光谱法"具体实例讨论如何将这种教学模式运用于《仪器分析》课程教学中,用来改善学生学习的主动性,提高教学效果。

汉英颜色词的文化意义对比分析

颜色词除指称物质颜色外,在更多的场合被赋予不同的文化引申义、联想义和象征义。红、黄、蓝、绿、青、黑、白七种基本颜色词在汉英语中的文化意义虽然在某些方面有相同之处。但由于历史、文化、地域的不同,在更多方面呈现出差异,甚至出现语义相悖的情况。为了准确表达和翻译颜色词,必须重视其在汉英语中文化意义的异同。
