一年级学生理解应用题的思维过程及其特点

問題 在小学数学教学中,应用題教学是具有重要意义的。学习应用題既能帮助儿童更好地掌握基本数学概念,培养儿童运用計算技巧解决实际問題的能力,同时也是发展儿童邏輯思維的手段。所以培养儿童解答应用題的能力是小学数学教学中重要的一环。 解答应用題是一种复杂的智力活动。儿童的語文水平、运算技巧虽然对解答应用題有一定的影响,但是解答应用題的先决条件是儿童了解組成題目的数量間的联系及相依关系。在教学中常常发現有些儿童虽然能机械地指出題目中的条件与問題,但不知道問     

AN EMPIRICAL STUDY OF OVERSEAS CHINESE MANAGERIAL IDEOLOGY*

This study of managerial ideology focuses on the question of legitimacy and attempts to reconstruct the way in which the role of the chief executive is perceived in the context of Overseas Chinese economic cultures. The location of the study is Hong Kong, Taiwan and Singapore and those studied were 72 chief executives in Chinese business organizations. Three determinants of present-day beliefs are traced to the socio-historical legacy of China, and these are identified as paternalism, personalism and a defensiveness derived from insecurity. The workings of their influence are traced via perceptions of the self, of relationships, of organization, and of society at large, to explain how executives rationalize their behaviour and their roles.     

The Effects of Self‐Diagnostic Information on Risk Perception of Internet Addiction Disorder: Self‐Positivity Bias and Online Social Support1

This article demonstrates how self‐diagnostic information (presence of symptoms on an inventory) influences the risk perception of Internet addiction disorder (IAD). The authors also highlight 2 tendencies—self‐positivity bias and online social support—that are characteristics of risk perception of IAD. In 3 studies, it was found that if no contextual information was provided, respondents estimated their risk of IAD as higher than when contextual information (symptoms) was provided. They were also less prone to self‐positivity (i.e., the disposition for people to estimate their risk as lower than others). Finally, our research provides evidence that online social support moderates these effects.     

The Effects of Electronic Word of Mouth on Product Judgment and Choice: The Moderating Role of the Sense of Virtual Community1

Electronic word‐of‐mouth (WOM) communication influences potential consumer attitudes and behavioral intentions toward a product. Since consumers frequently assess online information based on their relationships with communities, rather than with individuals, online communities themselves function as referents for assessing information quality. This study examines whether consumer perceptions toward virtual communities (i.e., sense of virtual community or SOVC) moderate the perceived influence of product comments on attitude and purchase intention. This study manipulated 2 scenarios involving positive comments and negative comments regarding a newly issued game product. Analytical results indicated that SOVC reinforced the influences of online comments on attitude and purchase intention. Thus, marketers should consider the role of virtual communities when implementing WOM strategy online.
