Classroom action research on formative assessment in a context-based chemistry course

Context-based science courses stimulate students to reconstruct the information presented by connecting to their prior knowledge and experiences. However, students need support. Formative assessments inform both teacher and students about students’ knowledge deficiencies and misconceptions and how students can be supported. Research on formative assessments suggests a positive impact on students’ science achievement, although its success depends on how the formative assessment is implemented in class. The aim of this study was to provide insights into the effects of formative assessments on achievement during a context-based chemistry course on lactic acid. In a classroom action research setting, a pre-test/post-test control group design with switching replications was applied. Student achievement was measured in two pre-tests, two post-tests and a retention test. Participants were Grade 9 students from one secondary school in the Netherlands. Repeated-measures analysis showed a significant effect of formative assessments on students’ achievement. During the implementation of the formative assessments, intriguing discussions emerged between students, between students and teacher, and between teachers. Adding formative assessments to context-based approaches reinforces their strength to meet with the current challenges of chemistry education. Formative assessments affect students’ achievement positively and stimulate feedback between students and teacher(s).     

美国传教士伯驾在华医疗事业影响述论

伯驾（Peter Parker，1804—1888）是美部会派往中国的第一位医药传教士。他在华期间的医疗活动不仅对基督教在华传教事业产生了一定影响，尤其在中美医学交流史上写下了浓重的一笔，对中国医学由传统向现代的嬗变起了重要的推逐作用。     

系统功能语言学对外语教学的启示

系统功能语法包括“系统语法”和“功能语法”两个部分，但这不是两种语法的简单总和，而是一种完整的语言理论框架的两个不可分割的部分．从韩礼德时语言学和语言的一些基本观点，本文进一步探索贯穿于他的系统功能语法的理论核心。本文主要讨论了系统功能语言学的六个主要思想：纯理功能的思想，系统的思想，层次的思想，功能的思想，近似的或盖然的思想，语境的思想。韩礼德的系统功能语法思想时外语教学具有深刻地的启示意义。本文主要从四个方面来论述这个问题：把外语作为系统来教，语言形式与语言功能在外语教学中并重，在语境教学中进行词汇的文化和语用知识导入。     

批判格莱斯合作原则,探索理解会话含义的新途径

:由于会话含义是隐含于字面意义中的说话者的真实意义 ,缺乏直观性 ,这就为语言的理解 ,特别是跨文化交际中会话含义的理解带来了困难。而格莱斯合作原则只是在微观方面分析了会话含义的产生 ,具有自身的局限性 ,只有结合宏观方面 ,把二者统一起来 ,才能全面地理解会话含义     

语法里的歧义现象

歧义是比较常见的语法现象.最普通的歧义由多义词引起.另外,句子构造层次、语法关系、成分的类型不同,也会造成句法歧义.词汇以外的原因引起的歧义是语境歧义.这三种歧义现象使语言的运用更加丰富多彩.     

Teacher Judgments of Student Reading and Math Skills: Associations With Child- and Classroom-Related Factors

The purpose of the study was to examine whether students’ linguistic skills and task-avoidant behavior (i.e., the child-related factors) and the mean level of academic skills (reading comprehension and math) of classmates (i.e., the class-related factor) are associated with teacher judgments of children’s reading comprehension and math skills. The participants were third-grade Estonian-speaking students (n?=?656; age 9?11 years) and their classroom teachers (n?=?51). The results of the structural equation modeling path analyses indicated that teachers tend to judge students showing higher academic and linguistic skills and lower avoidance behavior as higher on the reading comprehension and math skills. In contrast, the classmates’ higher academic skill level was related to lower judgments of individual children’s reading comprehension and math skills by teachers.
