CILT2000: Visualization and Modeling

CILT2000 helped VisMod evolve from a collection of local and distinct research and development efforts into a solid field of education. Previous intellectual efforts focused around a) modeling and simulation tools, b) visual explanation tools, c) visual data analysis tools, d) exploring student needs in the context of VisMod, and e) exploring instructional frameworks for VisMod. These focus areas have evolved in two main trajectories, representing the evolution of the field, the generalization trend, which seeks to identify general principles and guidelines for designing learning environments, and the equitable application trend, seeking to use knowledge gained in the field to leverage education in general.     

辛亥革命时期资产阶级革命派的政体设计反思

辛亥革命结束了在中国持续长达两千余年的封建帝制，在形式上确立了资产阶级民主共和制度。这一时期，为了维护这种民主共和制度，资产阶级革命派对当时中国政体的设计可谓煞费苦心。但不管是总统制，还是责任内阁制，都因设计上的不足，不能引导中国走向富强。     

初教专业历史课程设置及教学浅议

随教育事业的发展，素质教育的深入，三级师范已不能满足小学教育的需要，在一些教育发达地区已实现师范教育本科化。由于我省基础薄弱，最近几年才进行初教专业的探索，笔在承担初教专业历史教学任务，经过几年的探索性教学实践后，对我省五年制师范课程中关于历史课程的设置及教学方面应合理安排课程设计，采用较为合理的教学方法与手段，使学生知识理论与教学技能获得全面发展作一些探索。     

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.

Students with special educational needs within PISA

Abstract

Since 2003, the Programme for International Student Assessment (PISA) has included students with special educational needs (SEN), identified as those with functional disabilities, those with cognitive/behavioural/emotional disabilities and those with limited test language proficiency. While the number of countries and included students has increased with each test administration, the percentage of students with SEN remains extremely low. The inclusion of these students is not an intentional PISA design parameter but rather a response to the interaction between the need to maintain strict sampling criteria and country-level educational mandates to include SEN students in standardised testing. Based on the analysis of student participation and performance across four cycles of PISA (2003–2012), this paper examines the challenges that exist in current PISA procedures related to: student sampling, eligibility and identification; assessment methodology; and reporting results. PISA practices, their limitations for scientific inferences and recommendations for design improvements are given.

多因素问题的科学探究

尽管控制变量法对某些多因素问题失效,但当前探究教学中几乎压倒性地用控制变量法来研究多因素问题,此项研究调查了这种做法对中学生探究方案设计所造成的影响,结果表明:在具有简单多因素实验设计的意识和能力的学生中,初一学生的比例大于初二、初三和高一学生的比例,这说明过度的控制变量法训练,削弱了多因素实验设计的意识和能力,窄化了学生探究方案的设计思路.
