案例教学法的本质特征及其适用性分析

本文认为案例教学法是一种由培训者控制、受训者作为主体参与、围绕真实案情展开的特殊教学方法,有别于以教师为中心的传统教学方法;具有过程的开放性、信息的对称性、思维的多元性与创新性等特征,其过程的意义往往大于结果。案例教学法在培养学习者分析和处理实际问题的能力、处理复杂事件的应变能力以及团队精神等方面表现出良好的适用性。

Improved fast intra prediction algorithm of H.264/AVC

With advanced prediction modes of intra prediction, intra coding of H.264/AVC offers significant coding gains compared with previous video coding standards. It uses an important tool called Lagrangian rate-distortion optimization (RDO) technique to decide the best coding mode for a block, but the computational burden is extremely high. In this paper, we proposed an improved fast intra prediction algorithm including block type selection and mode decision algorithm based on analysis of edge feature of a block. Our algorithm filters out unlikely block type and candidate modes to reduce the RDO calculations. Experimental results showed that the proposed algorithm can reduce the computation complexity of intra prediction from 52.90% to 56.31%, with 0.04 dB PSNR degradation and 2% increase of bit rate.

我国民办幼儿园发展的现状、困境及突破——以四川省广元市为例

随着国家对民办教育的高度关切,民办学前教育已经成为我国教育事业发展中的重要一环。广元市民办幼儿园教育蓬勃发展,但同时又面临重重困境。政府扶持力度羸弱,监管不足;区域发展不平衡,资源分配不均;收费高,乱收费现象严重;急功近利,小学化问题突出;教师层次差异大,流动性强。建议:深化教育供给侧改革,实现民办园健康发展;建立结对帮扶模式,优化民办园资源配置;树立科学教育观念,提高民办园教学质量;完善教育监管体系,规范民办园收费制度;关注园长领导素养,稳定民办园教师队伍。     

Triadic interaction in clinical task-based interviews with mathematics teachers

A clinical task-based interview can be seen as a situation where the interviewer–interviewee interaction on a task is regulated by a system of explicit and implicit norms, values, and rules. This paper describes how documenting and mapping triadic interaction among the interviewer, the interviewee, and the knowledge negotiated can be used to increase procedural replicability of the interview and accuracy of drawn conclusions about the interviewee’s thinking process. Excerpts from interviews with 25 inservice mathematics teachers working on a task to make up a problem whose solution requires division of two fractions are discussed. The excerpts illustrate the relationship between methodological decisions taken by the interviewer during the interview and the applicability of the interview output to the research questions. A divergent analysis of the interviews with these teachers, which spanned over two years and were conducted by four interviewers, is used to offer a framework for analyzing data collected in clinical task-based interviews.     

Giving Education a Bad Name: Bookish Boys in Contemporary American School Stories

This article discusses contemporary American school stories that appear to advocate learning and literacy as a democratic good, but actually undermine democratic possibilities by teaching young readers to think of academic inquiry as a means to selfish, petty ends. Since “learning” and “literacy” are catchwords for educators dedicated to remedying neoliberal inequities, it is understandable why authors of school fiction such as Andrew Clements and Tommy Greenwald are celebrated by educators for foregrounding the exploits of bookish characters. Yet, as is shown, the narrative arcs in works such as Frindle by Clements and Charlie Joe Jackson’s Guide to Not Reading by Greenwald ultimately endorse the market consciousness, deregulation, and excessive individualism for which neoliberalism is known. Examining the ways in which these two novels intersect with ongoing debates over literacy standards, learning outcomes, and academic honesty, it is argued that the didactic-pedagogical imagination in contemporary American fiction for young people has a biased conception of student development and life preparedness, ideologically at odds with democratic curriculum provision.
