"胚胎分割及胚胎干细胞"教学设计

1教材分析 “胚胎分割及胚胎干细胞”是普通高中课程标准实验教科书人教版生物选修三“现代生物科技专题”中的内容。该内容属于专题三胚胎工程中第三节“胚胎工程的应用及前景”的第二课时。选修模块是为了满足学生多样化的需要而设计的,它有助于拓展学生的生物科技视野,增进学生对生物科技与社会关系的理解,提高学生的实践和探究能力。但鉴于教学内容的现代性与我校实验设备条件之间的矛盾,因此发展探究能力将比较多地集中在学习资料的收集分析、撰写专题综述、口头交流、讨论或辩论等方面,并辅以适量可行的调查或实验活动。

Reproducing peace? A CRT analysis of Whiteness in the curriculum and teaching at a University of The UN

Peace and conflict studies (PACS) higher education is a blossoming field. Literature (both conceptual and conjectural) and research (theoretical and empirical) has proliferated in recent decades. This paper details case findings from an ethnographic study with university-based PACS educators completed at one University of The United Nations in 2015. The six-month ethnography involved document analysis, participant observation, and semi-structured interviews with 25 peace scholars and 108 postgraduate students. Data was thematically coded and analyzed using concepts from critical race/critical Whiteness studies. This paper outlines the study and explores the theme of Whiteness that emerged from data. Findings point toward the cultural reproduction of Whiteness in the faculty, pedagogy, and institution. The paper concludes with a discussion of implications concerning global equity and ‘post-structural violence’ in PACS education, as well as a call for further research into the role of peacebuilding education in broader social change.     

Peace education and peace education research: Toward a concept of poststructural violence and second-order reflexivity

Peace and conflict studies (PACS) education has grown significantly in the last 30 years, mainly in Higher Education. This article critically analyzes the ways in which this field might be subject to poststructural critique, and posits Bourdieusian second-order reflexivity as a means of responding to these critiques. We propose here that theory-building within PACS education is often limited by the dominance of Galtung and Freire, and that, while the foundational ideas of positive and negative peace, structural and cultural violence, conscientization, reflexivity and critical pedagogy are still relevant today, they nevertheless need to be combined in new ways with each other, and with Bourdieu’s notions of habitus and field, to adequately respond to poststructural critique. Thus, we call here for greater field-based reflexivity in twenty-first century PACS.     

PACS系统应用及其遵从性设计

PACS系统是实现医学影像信息管理的重要条件，它对影像的采集、显示、储存、交换 和输 出进行数字化处理，最终实现影像的数字化储存和传送，使影像诊断技术走向更深层次。顺 利实现PACS系统设计方案和系统构建任务具有非常重要的意义。系统总的设计原则是根据医 院自身情况进行，要遵从DICOM标准化设计，达到标准化，模块化，可扩展性，灵活性，实 时性的目标。     

现代信息化教学在医学影像教学中的价值

Children's Reactions to the Receipt of Direct and Indirect Help

First, third, and fifth graders' ( N = 201) reactions to 2 types of and (direct help [answers] and indirect help [hints]) commonly used by helpers to assist children were examined. The children were randomly assigned to receive either direct or indirect help on a task, and then were asked to try a similar task immediately and again a few days later. Direct help was expected to elicit dependency, whereas indirect help was expected to elicit independent reactions. Age and/or sociocognitive level were predicted to moderate the effects of help. Direct help resulted in feelings of threat, low perceived control, and high dependency help-seeking for girls, but not for boys. Boys who received indirect help and understood the notion of consistency of personality requested less dependent help than did boys with less of this sociocognitive skill. Moreover, children high in the understanding of consistency of personality were more autonomous (i.e., helped themselves more) in the indirect than in the direct help condition.     

Influences on Computer‐based Problem Solving: help facilities,intrinsic orientation,gender and home computing

Abstract Microcomputer aided instruction often provides pupils with a means of obtaining assistance. The findings of an initial study suggested that experience on a microcomputer task with a help facility does not necessarily lead to improved performance. The frequent use of a help facility was associated with poorer concurrent performance and was associated with poorer performance when the help facility was no longer available. The possibility that the effects of the help facility were confounded by other variables led to a second controlled investigation of this issue. This experiment confirmed that a help facility was of no significant benefit and appeared to interfere with some aspects of the pupils’ performance. The initial investigation also examined other sources of influence on computer‐based problem solving. It was found that, as predicted, pupils with an intrinsic orientation tended to use a help facility less and to choose more difficult problems. However, pupils who were intrinsically orientated were not found to be any better at computer‐based problem solving than pupils who were less intrinsically orientated. Finally, no differences were found in computer‐based problem solving according to gender or the pupils’ access to home computers.
