中学数学学困生题后反思的元认知技能培训

在教学环境下,如何提高个体的元认知水平,一直是元认知研究领域的焦点课题.通过控制课堂教学,对“题后反思”法的训练效果进行研究是很有必要的,由此得出:(1)数学学优生与学困生在元认知技能方面存在显著性的差异;(2)经题后反思的短期培训后,数学学困生在元认知技能方面有显著性的提高,但是与学优生的差异仍然显著.     

组合积分与若干递推公式

积分问题在传统数学中已臻完美，但在有理函数的积分中如果结合具体问题适时采用组合方法来解决，将会收到事半功倍之效．作者在文[1]中曾经探讨了四类有理函数的组合积分法，在此基础上，本文给出常见分母二次型、常见分母三次型有理函数的组合积分方法，以及若干递推公式。     

An ecological approach to the on-line assessment of problem-solving paths: Principles and applications

In this paper, we propose a theoretical framework for designing on-line situated assessment tools for multimedia instructional systems. Based on an ecological psychology approach to situated learning, a graph theoretic methodology is applied to monitor students' performance (solution paths) throughout the learning activity. Deviation of the student's path from the target (expert) path generates indicators which can function as alerts to the student and to the instructor. The information collected in the dribble files and presented visually enables the instructor to identify problems quickly and intervene appropriately. The feasibility of the methodology is explored in case studies describing three instructional systems that teach (1) critical thinking and problem-solving skills, (2) principles of hemodynamic monitoring and treatment, and (3) orthodontic treatment, respectively.

The Value of Fiction as Management Training

ABSTRACT

Reading fiction can teach sophisticated management skills. The difference between paraliterary fiction that focuses on escaping reality and literary fiction that analyzes reality is important. All reading can help improve basic literacy including increased comprehension and reading speed. Intermediate skills provide the manager with specific lessons on how to manage. Advanced skills, obtained from reading literary fiction, include empathy, the ability to interpret and create sophisticated texts, and an increased possibility of recognizing the “truth” in any environment. Traditional business publications offer more direct training but often overlook the complexities that the experienced manager will encounter and overemphasize the possibilities for success.

Column Editor’s Note This JLA column will consider issues of education and training for management positions in libraries and other information organizations from the perspectives of both the provider and the recipient. The column will appear in odd-numbered issues of the journal and focus on management education/training at various stages of the individual's career including the effectiveness of these efforts, their content, and the specific challenges of teaching and learning within the field of librarianship. The column will address both theoretical and practical concerns. Prospective authors are invited to submit articles for this column to the editor at aa3805@wayne.edu.

求解法在数字电路课程教学中的应用

触发器是时序逻辑电路的基本单元,在数字电路系统中具有十分重要的地位。文章提出一种“问题求解教学法”———即先引出问题,寻求问题的解决方法,最终圆满解决问题。教学实践表明,该教学法对激发学生的学习兴趣,引导学生独立思考,提高其创新思维能力,加深对触发器理解和记忆,均有很好的积极意义。     

Development of learning to learn skills in primary school

In Finland, schools’ effectiveness in fostering the development of transversal skills is evaluated through large-scale learning to learn (LTL) assessments. This article presents how LTL skills—general cognitive competences and learning-related motivational beliefs—develop during primary school and how they predict pupils’ CPS skills at the end of sixth grade. The six-year follow-up of 608 pupils shows that cognitive competences demonstrated in the beginning of the first grade in a learning preparedness test predict both later cognitive LTL competences and CPS, but their development is not fully determined by earlier individual differences in learning preparedness in the first grade. Motivational beliefs begin to be related to cognitive LTL performance gradually from age 10 on, and they may have a slightly stronger effect on CPS than on cognitive LTL performance. It is concluded that the development of CPS is partly depending on pupils’ initial learning preparedness and the development of their LTL skills.
