"反思型"培训模式:综合课程教师继续教育的理智选择

深入分析新一轮基础教育综合课程改革和实施的状况,倍感师资问题是制约综合课程改革主要的、“瓶颈性”的因素。要想真正消解综合课程实施中来自教师的制约作用,当务之急就是迅速而有效地对在职教师进行培训。本文通过理论与实践层面的分析,阐述了选择反思型的教师培训模式的必然性,提出了实施这一培训模式的策略和思路。     

中国西部旅游资源弱势区发展旅游的研究——以四川绵阳为例

西部大开发战略,给西部旅游业的发展带来了千载难逢的好机会。但西部有很多县市属旅游资源弱势区,这些地区大多比较贫穷落后,除旅游资源外其他资源也相对匮乏,它们如何谋求发展?文章以四川绵阳为例,在用耗散结构理论深入系统研究绵阳旅游业的基础上,按照国际惯例采取与世界旅游组织接轨的理念和方法,研究并讨论了绵阳大一统旅游这一案例及其与绵阳区域旅游发展的关系。实证研究表明,绵阳大一统旅游对提升绵阳形象,促进绵阳旅游业形成龙头产品,增强绵阳旅游业的竞争力等具有积极作用。这为西部资源弱势区旅游发展提供了一种新的模式和启示。     

关于儿童欺负行为研究的思考

儿童欺负行为主要发生在校园或者以校园为媒介的社交群体内,是一种常见的校园不良行为,并有可能发展为校园暴力。对欺负行为及其动机进行分析,培养儿童健康人格,采取科学教养方式,加强正面教育是对欺负行为进行有效干预的重要途径。     

从战时共产主义向新经济政策的转变看列宁的与时俱进

列宁亲自制订的战时共产主义政策与新经济政策内容截然不同，却均抓住了各自面临的主要矛盾，拯救了新生的苏维埃政权。剖析其问之实事求是态度及与时俱进精神，了解其中对经典社会主义理论之突破与发展，对把握列宁主义精髓大有裨益。     

Mathematical Modeling in the Primary School: Children's Construction of a Consumer Guide

This paper examines 6th grade children's local conceptual development and mathematization processes as they worked a comprehensive mathematical modeling problem (creating a consumer guide for deciding the best snack chip) over several class periods. The children and their teachers were participating in a 3-year longitudinal teaching experiment in which sequences of mathematical modeling problems were implemented from the 5th grade (10 years of age) though to the 7th grade. In contrast to traditional problem solving, mathematical modeling requires children to generate and develop their own mathematical ideas and processes, and to form systems of relationships that are generalizable and reusable. Reported here is a detailed analysis of the iterative cycles of development of one group of children as they worked the problem, followed by a summary of the mathematization processes displayed by all groups. Children's critical reflections on their models are also reported. The results show how children can independently develop constructs and processes through meaningful problem solving. Children's development included creating systems for operationally defining constructs; selecting, categorizing, and ranking factors; quantifying quantitative and qualitative data; and transforming quantities.

对邓小平教育思想的几点思考

邓小平教育思想是邓小平理论的重要组成部分,其内容主要包括:关于教育的战略地位,邓小平认为在我国社会主义建设过程中应始终把教育摆在优先发展的战略地位,教育是一个民族最根本的事业,全党和全社会都要尊重知识,尊重人才;关于教育平等问题,“文化大革命”结束后,邓小平恢复了中断十年之久的高考制度,使广大学子在接受高等教育机会上平等竞争,此外他还特别注重教育的普及和提高;关于要加强对学生的思想政治教育问题,邓小平十分关注教育发展的方向和人才培养的标准,注重对学生的理想信念教育,为新时期加强对学生的思想政治教育指明了方向;关于教师的地位和待遇,邓小平提出要提高教师的政治地位和社会地位,特别强调要提高教师待遇,充分调动广大教师的积极性和创造性。     

Comparing Models of Change to Estimate the Mediated Effect in the Pretest–Posttest Control Group Design

Models to assess mediation in the pretest–posttest control group design are understudied in the behavioral sciences even though it is the design of choice for evaluating experimental manipulations. The article provides analytical comparisons of the four most commonly used models to estimate the mediated effect in this design: analysis of covariance (ANCOVA), difference score, residualized change score, and cross-sectional model. Each of these models is fitted using a latent change score specification and a simulation study assessed bias, Type I error, power, and confidence interval coverage of the four models. All but the ANCOVA model make stringent assumptions about the stability and cross-lagged relations of the mediator and outcome that might not be plausible in real-world applications. When these assumptions do not hold, Type I error and statistical power results suggest that only the ANCOVA model has good performance. The four models are applied to an empirical example.
