Fostering the Suspension of Disbelief: The Role of Authenticity in Goal-Based Scenarios

Goal-based scenarios (GBSs) have become a mainstay of Andersen Consulting’s 900 million dollar efforts to train its employees. Utilizing a theoretical framework based upon social constructivist theory, we create classroom learning environments that use theatrical elements to simulate real-world client engagements. The suspension of disbelief, however, is one factor that can be detrimental to human learning in immersive simulations. This paper describes one of our school designs, constructs a theoretical framework to support our approach, examines some of the factors associated with the suspension of disbelief, and makes recommendations for enhancing the authenticity of goal-based scenarios.     

最大吸氧量对青少年100m和800m训练项目的影响

采用文献资料法、实验法、数理统计法对某重点中学体育训练队的16名男女学生进行Pwc170台阶实验测试分别推算出各受试学生的Vo2m ax,然后对男女各组100m和800m进行相关性分析,根据测试结果及分析显示,Vo2m ax对男生100m与800m成绩的线性关系达到了显著水平,男女生存在差异。对青少年的最大吸氧量的预测有非常重要的意义。     

中外优秀男子百米分段速度的研究

为了缩小中外男子百米速度的差距,本文通过文献资料法、影片拍摄法和数理统计法,对男子百米国际优秀水平组、国际水平组、中国组三组每10米段的平均速度进行了分析,通过研究结果对百米加速跑、途中跑和终点跑段落进行了重新划分;认为造成中国男子百米成绩差距的主要原因是:起跑至10 m的平均速度较慢,维持最大速度的能力差.

The use of portfolios to foster professionalism: attributes,outcomes, and recommendations

The main objective of this research was to review the characteristics of portfolios and their outcomes for teaching professionalism to undergraduate medical students. A systematic review on the use of portfolios in teaching professionalism to medical students identified 1257 papers. Of these, 11 articles met all inclusion criteria. According to the papers, the use of portfolios for teaching professionalism shows versatility, supports learning strategies and has the potential to be used in different contexts, including for formative and summative purposes. The weaknesses were based on the artificiality of the reflections, deficient instructions, time-consuming processes and preference among students for other teaching methods. Students complained about feeling that the reflection was ‘forced’, and they tended to write based on social conventions rather than reveal their true thoughts. Reflection is a powerful component of the portfolio, but the method by which it is taught could easily ruin its potential to boost professionalism. Requiring reflection did not ensure its achievement; increased understanding by students regarding how and why they were doing it, the clarity of assessment methods and constructive feedback might strengthen the potential for success. A framework was designed to support faculty members in developing and applying portfolios with a clear and broad view of this teaching strategy.     

资源型城市绿色增长能力评价研究

资源型城市是我国重要的战略保障基地,其绿色增长能力成为彰显国家绿色增长水平的重要途径。本文构建了以社会经济、资源环境、生活质量为基础系统,以政策支持为交互系统的资源型城市绿色增长评价模型,以2000-2013年17个典型资源型城市为研究对象,运用三角模糊熵组合赋权的灰色关联投影方法测算绿色增长指数,进行绿色增长能力评价。研究结果表明:三角模糊熵组合赋权的灰色关联投影法是评价资源型城市绿色增长能力的有效方法。国家相关政策的颁布实施是促进资源型城市实现绿色增长的主要动力。中国资源型城市绿色增长能力不断提高,依据绿色增长能力的大小,可将中国资源型城市划分为创新升级型、发展成熟型、稳步提升型和意识崛起型四个发展类型。

Dress rehearsal: a Bourdieusian analysis of body work in career portfolio programs

This article examines how career portfolio programs at two secondary schools establish corporeal regimes. Both programs require students to compose portfolios that plot their trajectories through school and into paid work. Prior to graduation, students defend their portfolios before panels of educators and businesspeople. Employing the Bourdieusian concepts of capital and habitus, this article investigates how these programs set up systems that value certain kinds of bodies. Further, it examines how students negotiate these systems and display different kinds of bodies in different kinds of ways. Ultimately, it is argued these disparate bodily performances are read by authorities as indicators of the types of paths students are travelling or should travel into the future.
