Examining the effect of multiple writing tasks on Year 10 biology students’ understandings of cell and molecular biology concepts

This paper reports on a study that examined the cumulative effects on students’ learning of science, and perceptions of the role of writing in learning, when the students engaged in multiple writing tasks with planning strategy support. The study was conducted with Year 10 biology students who completed two consecutive units on Cells and Molecular Biology. A mixed method study was implemented using a pre-/post-test design with a focus on student performance on higher order conceptual questions, and semi-structured interviews with treatment students after the completion of each unit of study. Results from the quantitative component indicated that multiple, non-conventional writing had a significant benefit in helping students learn Molecular Biology. The results for the Cell unit were not so conclusive suggesting the strategies are most useful for novel content. The interviews with students demonstrated that they understood and engaged successfully with both the conceptual and linguistic demands of the tasks. These findings, taken as a whole, confirm that multiple writing tasks can support effective student learning, provided various pedagogical conditions are met.     

综合英语中的学习趣味性与学习动机的提高

动机是指学习某种语言的愿望及为此付出的努力和对学习某种语言所持的综合态度。当前,综合英语授课仍以教师讲授为主,教师花大量时间通过例句来讲解语言点、句法和课文内容,所以课堂气氛沉闷,往往是老师在唱"独角戏"。教师若能在教学过程中穿插一些趣味教学法,将能起到调动学生学习动机的作用,帮助老师提高课堂学习效率。     

法学教学中实践技能训练之我见

实践是法律的生命。传统的法学教育缺乏师生互动，不能体现法学专业大学生学习中的主体性。加强法学实践技能训练，是现代高校法学教育的大趋势，具体地说就是对实践技能训练方式的开发、适用和检讨。

社区远程教育为空巢家庭服务的模式

社区远程教育是建设和谐文化的重要途径。空巢家庭目前在中国一直呈上升趋势,由于空巢家庭成员本身所具有的特点,使他们成为社区远程教育的重要对象。本文针对空巢家庭特点,从教学资源、教学内容、教学方式和考核方式等几个角度,提出社区远程教育对这一群体的教学服务模式。     

在核心课程理念下建构成人科学教育课程

我国公众科学素养与发达国家相比还有较大的差距,而且年龄越大,素养还越低。在成人高等教育的通识教育课程中．设置科学教育课程非常必要。核心课程是成人科学教育的一种最好的课程模式,它具有学际性、开放性、生成性等特点,更适合成年人进行专题学习。     

论大学知识现代性的四个面向

国家主义、民族主义、自由主义与科学主义是大学知识现代性的四个重要面向。高深学问由原来的整体性、非世俗化与自由的知识转化为分科、世俗性、功利性知识,是国家民族之间生存竞争所导致的结果,民族国家的构建是大学知识现代化的内在驱动力。学问体制与国家在宏观与微观层面的互动对大学的现代化转型产生了影响。     

影响英语自主学习能力的因素探析

在中国,学生在英语学习过程中表现出来的被动性、依赖性问题仍旧存在。文章通过对影响学习者自主学习因素的分析,提出了以元认知策略培训为主,以优化学习者自我效能感、归因、动机等因素的组合,培养学习者积极、乐观的情感为辅的教学模式,以提高学生的自主学习能力。     

The persistence of preschool effects: Do subsequent classroom experiences matter?

Using rich longitudinal data from the Early Childhood Longitudinal Study-Kindergarten cohort (ECLS-K), we find that children who attended preschool enter public schools with higher levels of academic skills than their peers who experienced other types of child care (effect size of .14). This study considers the circumstances under which the preschool advantage persists, that is, the types of classrooms in which students who did not attend preschool “catch up” to their counterparts who did. Specifically, we focus on two dimensions of the early school environment—class size and the level of academic instruction provided. The findings suggest that most of the preschool-related gap in academic skills at school entry is quickly eliminated for children placed in small classrooms and classrooms providing high levels of reading instruction. Conversely, the initial disparities persist for children experiencing large classes and lower levels of reading instruction. These results point out that the longer-term effects of early childhood experience partly depend on classroom experiences during at least the first years of school.     

科学技术哲学的科学教育解读

科学技术从根本上改变了人类的生存方式和发展模式,它是人类能够更好地生活的基本保证,但并不等于生活的全部智慧。科学技术虽然给人类带来了高度发达的物质文明,却不能为人类提供生活何以值得过下去的理由。该问题的解决必须依靠在正确的科学技术哲学思想指引下的科学教育,并从系统哲学、生态哲学和技术哲学三个维度,对如何提高和发展科学教育提出了初步设想。只有在正确的科技哲学观的指导下,科学教育的质量才会得以提高,全民科学素质的提升才可能得以实现,人们才会获得更好的生活。
