Science learning and a Sense of Place in a Urban Middle School

This paper offers an analysis into low-income, urban middle school children's sense of place and what and how their sense of place matters in science learning by focusing on the following questions: In what ways is students' sense of place leveraged in a science classroom? How does the content and context of science class shape how students leverage their sense of place? What learning opportunities emerge when sense of place is leveraged in class? Drawing from an ethnographic investigation into an environmental statistics class in a mid-sized public middle school, we examined sense of place events from their source, process, and outcome perspectives. Our findings are presented from two aspects of sense of place events, (1) characterizing students' sense of place by exploring sources of the sense of place events, and (2) examining processes of how students' sense of place is being leveraged in the episodes. We also examine two kinds of tensions that emerge in the class when sense of place is leveraged by students and acknowledged by the teacher: epistemological tensions (related to what the students are learning) and procedural tensions (related to how they are learning).     

Making Sense of the Role of Culture in School Improvement

Addressing the need to find new ways for examining workplace cultures quickly and effectively in order to facilitate school improvement efforts, this article proposes a technique for carrying out such enquiries. By exploring the nature of school cultures and how they impact upon day-to-day encounters in classrooms, it illustrates how critical incidents can be analysed so as to help those in schools to understand themselves better in terms of those factors that shape their practice. It is argued that the proposed method has the potential to go beyond systems of external monitoring in such a way as to enable schools to develop procedures for self-review.     

Student Perceptions of a Summer Robotics Camp Experience

Research on the effectiveness of STEM-focused (science, technology, engineering, and mathematics-focused) schools and other learning experiences (e.g., short-term camps) on student outcomes is sparse. This study documented perceptions of STEM content and careers for elementary, middle, and secondary school students participating in university-based summer camps focused on robotics. Attitudes before and after the camp experiences were compared across gender groups and grade levels. Middle school students showed greater growth on the surveys compared to their elementary and secondary school peers. Implications for the design and evaluation of STEM experiences include looking at longer, more intensive experiences.     

初中生数感的培养策略

数感在义务教育数学课程中是一个全新的重要内容.目前初中生的数感培养存在的主要问题有:对数概念的理解脱离现实的生活,而且缺少个性化和多样化的理解方式;学生的估算意识薄弱,缺少估算的方法;学生之间缺乏有效的交流,抑制思维的发散;解决问题的能力有待提高.培养学生数感的策略有:在数概念的教学中,重视对数概念的切实体验与理解;注重对运算意义的理解,加强估算能力并鼓励算法多样化;在数学交流中领悟数感;在问题解决中培养和发展数感.     

Modelling in Primary School: Constructing Conceptual Models and Making Sense of Fractions

This article describes sixth-grade students’ engagement in two model-eliciting activities offering students the opportunity to construct mathematical models. The findings show that students utilized their knowledge of fractions including conceptual and procedural knowledge in constructing mathematical models for the given situations. Some students were also able to generalize the fraction model and transfer it to a new situation. Analysis of the students’ work demonstrates that they made use of four fraction constructs—part-whole, operator, quotients, and ratio. The activities also revealed difficulties in the students’ knowledge of fractions, some of which were overcome in the process of organizing and mathematizing the problem.

谈物理教学中学生问题意识的培养

学生问题意识的淡薄是制约其创新思维发展的重要因素。因此,教师在教学过程中要想方设法增强学生的问题意识,充分调动学生提出问题的积极性,让学生变被动掌握"静态"的物理知识为主动探索、研究"动态"的物理知识,从而真正成为学习的主人。

Cognition Research in Practice: Engineering and Evaluating a Middle School Math Curriculum

Abstract

How can research findings from cognitive and learning sciences be meaningfully applied in authentic settings to improve student learning outcomes in mathematics? Decades of basic research on how people learn has implications for the design of curriculum, instruction, and assessment. However, bringing research to practice involves simultaneously applying multiple design principles and raises pragmatic challenges of classroom contexts. Our project used research-based recommendations to systematically revise a widely used middle school mathematics curriculum and investigated whether the revised curriculum improved student learning in mathematics. In this article, we detail a replicable process for operationalizing and implementing multiple research-based principles and report findings from a large-scale experimental evaluation of this approach to estimate the potential impact on student learning.     

浅谈中学历史教学中的忧患意识教育

忧患意识是中华民族的优良传统。江泽民同志在党的十六大上更明确提出“一定要增强忧患意识,居安思危”。然而,由于舆论宣传、教育理念等的偏差,导致当前国人尤其是青年学生忧患意识淡薄。中学历史学科中,对学生进行忧患意识教育的内容既十分丰富又具体生动,具有其他学科无法取代的优势。在历史教学中,应结合学科特点,采取多种途径开展忧患意识教育,以增强青年学生的忧患意识。     

Citing Discourses: Making Sense of Homophobia and Heteronormativity at Dynamic High School

In this article, I draw on poststructuralist work on "citationality" to elucidate an urban high school's student culture and intervention efforts with regard to LGBQ issues. I contend that the language, ideas and practices of LGBQ issues and awareness among students and staff "cite" or draw on broader (and often competing) discourses of normalcy, sexuality, and/or "good teaching." I discuss how the citational process makes it difficult to bring about change, as well as the possibilities for bringing about change. The significance of this article is the way it explicates the discourses used to articulate and describe LGBQ people, issues, and intervention efforts; and how these discourses may hinder efforts to create LGBQ support and awareness in schools.     

甘肃省农村中学生音乐素养调查

调查发现,甘肃省农村中学生跟全国各地中学生一样,学生中喜欢音乐的人占到了全体人群的绝大多数,这种情况其实是与音乐在人性中的重要性原则相符合的。针对甘肃省农村中学生音乐素养存在的问题,提出几点建议:(一)采取先进的教学方法,提高学生音乐学习兴趣;(二)倡导音乐课程内容多元化;(三)为学生创设交流展示的平台;(四)转变家长对学习音乐的陈旧观念。
