新世纪拒斥这样的教学论——主流教学论困境的根源及其走出

主流教学论已陷于困境，因为这是游移于教学根基、缺乏批判思想、没有自己独特话语系统的理论。新世纪需要我们重视教学论新范式的研究，追求科学的教学论，开放教学论的研究边界，将其发展源泉置于教学实践之中。     

新中国政治教科书60年之演进

新中国政治教科书60年的发展跌宕起伏,在建国初期17年中"峰回路转"后,又深陷文革10年的"政治膨胀",幸得在改革开放中"柳暗花明",终在21世纪走上"康庄大道"。政治教科书编写从学科逻辑转向生活逻辑,从呆板木讷转向活泼明艳,从政治附庸向政治教育的本体性回归。     

试论我国先占制度的建立

先占,即先于他人占有而取得该物的所有权.作为取得物权的一种基本形式,先占制度在物权理论中的地位不言而喻.让人遗憾的是,我国现行<物权法>竟对其只字未提,不仅造成了理论上的矛盾与缺失,使得我国的民事法律自相矛盾,与外国法律也无法对接,更是在实务中形成了一些影响较大的盲区.诚然,现阶段建立先占制度可能会面对一些问题,但是因噎废食必然得不偿失.     

Investigating the impact of automated feedback on students’ scientific argumentation

ABSTRACT

This study investigates the role of automated scoring and feedback in supporting students’ construction of written scientific arguments while learning about factors that affect climate change in the classroom. The automated scoring and feedback technology was integrated into an online module. Students’ written scientific argumentation occurred when they responded to structured argumentation prompts. After submitting the open-ended responses, students received scores generated by a scoring engine and written feedback associated with the scores in real-time. Using the log data that recorded argumentation scores as well as argument submission and revisions activities, we answer three research questions. First, how students behaved after receiving the feedback; second, whether and how students’ revisions improved their argumentation scores; and third, did item difficulties shift with the availability of the automated feedback. Results showed that the majority of students (77%) made revisions after receiving the feedback, and students with higher initial scores were more likely to revise their responses. Students who revised had significantly higher final scores than those who did not, and each revision was associated with an average increase of 0.55 on the final scores. Analysis on item difficulty shifts showed that written scientific argumentation became easier after students used the automated feedback.     

Measuring Knowledge Integration Learning of Energy Topics: A two-year longitudinal study

Although researchers call for inquiry learning in science, science assessments rarely capture the impact of inquiry instruction. This paper reports on the development and validation of assessments designed to measure middle-school students’ progress in gaining integrated understanding of energy while studying an inquiry-oriented curriculum. The assessment development was guided by the knowledge integration framework. Over 2 years of implementation, more than 4,000 students from 4 schools participated in the study, including a cross-sectional and a longitudinal cohort. Results from item response modeling analyses revealed that: (a) the assessments demonstrated satisfactory psychometric properties in terms of reliability and validity; (b) both the cross-sectional and longitudinal cohorts made progress on integrating their understanding energy concepts; and (c) among many factors (e.g. gender, grade, school, and home language) associated with students’ science performance, unit implementation was the strongest predictor.

新媒体约稿方式的价值探讨

随着新媒体时代的到来,传统约稿方式的功能渐渐弱化。从新媒体定义出发,阐述采用电子函件约稿、网站约稿、微博约稿、短信约稿和虚拟社区约稿这5种新媒体形式的约稿方式的特点,分析它们在新传媒环境中对约稿方式的革新作用,并提出以新媒体为媒介的新型约稿行为的注意事项,为期刊约稿的"新媒体化"提供新的思路。     

面向关联数据的语义数字图书馆资源描述与组织框架设计与实现

本文提出了一个面向关联数据的语义数字图书馆资源描述与组织框架,该框架具有四个层次:元数据层、本体层、关联数据层和应用层,其核心是RDF语义元数据的构建与关联。以"图书、情报与档案学"领域的数据为例对该框架进行了实现,实现的重点是在本体层和关联数据层,包括相关本体的设计、普通元数据到语义元数据的自动转换、不同数据集间RDF语义链接的建立、关联数据的发布等。     

房地产业发展影响因子分析

浅议中职德育课实践活动教学教师的导学作用

活动课程中的教师应更充分地实现他对学生的导学性,这种导学性不仅仅表现在学生活动过程之中,而且要表现在学生活动之前所进行的活动设计、研究学生的直接经验、了解学生的活动兴趣、制定活动方式和活动计划,在活动结束后教师还应起到引导学生总结升华,由直接体验上升为知识、能力、技巧和良好行为习惯乃至科学的思维品质,这是现代活动课程的客观要求。
