Teachers’ perceptions of assessments of their mathematical knowledge in a professional development course

The purpose of the project reported in this article was to evaluate how assessing teachers’ mathematical knowledge within a professional development course impacted from the teachers’ perspective their learning and their experience with the course. The professional development course consisted of a 2-week summer institute and the content focus was geometry. We had decided to assess the mathematical learning of the teachers during this professional development course for various accountability reasons, but were concerned about possible negative by-products of this decision on the teachers and their participation. Thus, we worked to design assessment in ways that we hoped would minimize negative impacts and maintain a supportive learning environment. In addition, we undertook this evaluation to examine the impacts of the assessment, which included homework, quizzes, various projects, and an examination for program evaluation. Seventeen grade 5–9 teachers enrolled in the course participated in the study by completing written reflections and by describing their experiences in interviews. We learned that while our original intent was “to do no harm,” the teachers reported that their learning was enhanced by the assessment. The article concludes by describing the various properties of the assessments that the teachers identified as contributing to their learning of the geometry content, many of which align with current recommendations for assessing and evaluating grade K-16 mathematics students.

宋代的"结买"与"结籴"

结买、结籴是市易务官吏或由市易务招募商人,承办政府上供采买和购置沿边军粮的制度.其原则是政府预支本钱给承办人,预支数额要比原来政府采购的成本低.承办人以房、田契书和金银作抵押,并向主管部门立下保证文状,不能按时完成承办额要受处罚,赢亏自负.结买、结籴本钱的性质是预支款而非贷款,不必按市易赊贷法支付利息.由于结买上供预支本钱少,未能推广,结籴军粮虽可赢利,但多被市易务官吏及其关系户承办,存在经营不善、挪用结籴款等弊端,半途而废.     

Teachers’ Discussions Of Students’ Thinking: Meeting The Challenge Of Attending To Students’ Thinking

The purpose of this article is to describe findings from a study of teachers’ social interaction during discussions about students’ thinking. The goal of the discussions was for the teachers to interpret their students’ thinking as revealed from work on non-routine, thought-revealing mathematical tasks, known as model-eliciting activities. The research reported in this article focuses on instances during the discussions when the teachers engaged in what the researcher termed ‘mini-inquiries’, occasions during which the teachers inquired into why their students thought about the associated model-eliciting activities as they did or when the teachers inquired into the underlying mathematical complexities associated with the model-eliciting activities. During these mini-inquiries, the teachers typically engaged in one of four types of interaction patterns that enabled them to meet some of the challenges of attending to students’ thinking that are described in United States reform documents.

论高校德育在专业教学中的育人功能

本文认为充分发挥专业教学的育人功能是德育在高校的首要地位和教学活动的特点决定的；从教育规律看，德育离不开专业教学；各门课程也都蕴含着丰富的德育资源；而要充分发挥专业教学的育人功能，就必须强化全体教师的教书育人意识。     

在顺应幼儿兴趣中激扬幼儿潜能

在幼儿园师幼活动过程中,教师应顺应幼儿感知兴味开展教学活动,使其判断更加客观,理解更加透彻,接受更加自然,抒发更加强烈,运用更加自如,从而激扬其生命潜能。在教学中,倾听,融入幼儿的感知兴味,是对幼儿生命潜能的无声激励;随顺,能激扬幼儿的感知兴味,帮助幼儿达成生命主权的释放;跟进,能延伸幼儿的感知兴味。教师顺应了幼儿的兴味需要,当听即听,当随即随,当进即进,那么,幼儿的生命潜能将实现无限激扬。

中学年段教学管理综合评价研究

中学年段教学管理主要包括管理组织建设、教学运行管理、教学质量管理、教学辅助管理以及管理制度建设5个方面,通过建立综合评价指标体系,采用改进的层次分析法计算一、二级指标的相对权重。对某中学高中部3个年段进行综合评价的结果表明,该评价指标体系能够对中学年段教学管理水平做出客观、全面的评价,且简单易行。     

合作教育模式下学生顶岗实习考核及激励研究

合作教育模式下,顶岗实习的工作过程要以企业为主导,学生在企业技术人员的指导下,在固定的工作岗位上完成相应的工作任务。顶岗实习中,将实习成绩考核划分为企业考核和学校考核,并分配考核成绩比例;结合工程测量技术专业实习特点,建立了考核激励机制,并在合作教育基地进行了实施。这对于提高学生的实践动手能力具有重要激励作用。
