从易中天品三国到《高分子物理》教学

《高分子物理》是高分子材料科学与工程专业的一门专业必修基础理论课程,教授和学习都有非常大的难度。受易中天教授品三国节目的启发,结合作者多年教授这门课程的教学研究心得,从贴近生产生活的实例、讲授语言、类比等几个方面详细探讨了提高学生《高分子物理》学习兴趣的方法。     

Authority and whole-class proving in high school geometry: The case of Ms. Finley

Students’ experiences with proving in schools often lead them to see proof as a static product rather than a negotiated process that can help students justify and make sense of mathematical ideas. We investigated how authority manifested in whole-class proving episodes within Ms. Finley’s high school geometry classroom. We designed a coding scheme that helped us identify the proving actions and interactions that occurred during whole-class proving and how Ms. Finley and her students contributed to those processes. By considering the authority over proof initiation, proof construction, and proof validation, the episodes illustrate how whole-class proving interactions might relate to students’ potential development (or maintenance) of authoritative proof schemes. In particular, the authority of the teacher and textbook limited students’ opportunities to engage collectively in proving and sometimes allowed invalid arguments to be accepted in the public discourse. We offer suggestions for research and practice with respect to authority and proof instruction.

Knowing students as mathematics learners and teaching numbers 10–100: A case study of four 1st grade teachers from Romania

Researchers have increasingly linked teacher effectiveness with teacher knowledge of subject matter, curriculum, and teaching. Moreover, teacher knowledge of students has been regarded as another very significant component of teacher knowledge, influencing the classroom practice and student performance. Knowing students as mathematics learners means being aware of the ways students learn certain topics. This study examined the knowledge of students as mathematics learners displayed by four 1st grade teachers from Romania when designing and implementing a lesson on numbers 10–100. Findings show that knowledge of students as mathematics learners influenced the ways teachers planned and implemented their lesson. Teachers learned about students as mathematics learners from one series to another, and they tailored their use of manipulatives and classroom activities to meet the needs of their current students.     

以美术教育为载体 培养幼儿良好的品德行为

1.问题的提出不管是发生在北京地区,某大学生用硫酸烧灼伤害熊的事件,还是发生在宜春市区的中学生砸路灯行为,或者是发生在大学校园里的大学生杀人的案件,都使人感到触目惊心。目前青少年犯罪趋上升趋势。这是当今社会的一个严峻的问题。如何培养下一代良好的品德行为,这是每个教育者肩负的责任。     

Classroom Management in Young Learners English Teaching——Typical Problems and Effective Solutions

Classroom management is the orchestration of classroom life： planning curriculum, organizing procedures and resources, arranging the environment to maximize efficiency, monitoring progress, dealing with existent problems. Successful classroom management looked like magic shows because students in these classrooms seem to glide from one activity to the next. Successful classroom management contributes to students＇ good achievement. Effective classroom management is one of the key elements of importance for efficient school education. However, almost all English teachers face a same problem classroom management. In this paper, some typical problems and effective solutions in classroom management will be described, defined, or characterized.     

信息化环境中的互动物理教学探讨

关于物理探究式教学的调查

探究式课堂教学是以探究为基本特征的一种教学活动形式,符合教学改革的精神和实际,能使班级教学焕发出生机勃勃的活力。然而,探究式课堂教学在我国尚处于探索阶段,为了使探究式课堂教学有效的实施．还有很多工作要做,在理论研究、教学实践的同时,了解教师和学生对探究式课堂教学认识与认同情况也是很必要的,为此本文对部分教师和学生进行了物理探究式课堂教学的调查和分析。

Classroom mathematical practices in differential equations

This article describes the results of a design experiment conducted in one differential equations classroom. The purpose of the article is to present an analysis of the classroom mathematical practices that were established over the first half of the semester including instruction on first order differential equations. We discuss and illustrate our use of Toulmin’s model of argumentation to develop an analytical technique for documenting the emergence and stability of classroom mathematical practices. This analysis is significant in that it contributes to an emerging body of research on students’ learning in social context, in particular at the undergraduate level where such analyses are lacking. Our analysis also serves as a case to examine the construct of classroom mathematical practices in new light and to extend prior research by documenting two theoretical ideas; that practices can emerge in a non-sequential fashion with regard to both time and structure.
