数学分析教学中的若干意见

时高师数学分析的教学进行了探讨和研究，有针对性的提出了数学分析教学中应贯彻的六个“注重”：即注重引导学生主动建构数学分析知识结构；注重“良好的开始等于成功的一半”，讲好ε-语言；注重数学活动过程的教学；注重教学思想方法的教学，贯彻理论性与应用性相结合的原则；注重体系的内在统一，打破理论本身的封闭性和知识结构的单一性；注重发挥习题课的作用，上好习题课。     

Home learning environment and development of child competencies from kindergarten until the end of elementary school

Literacy and mathematical competencies are essential for a successful school career and precursors of these abilities develop in kindergarten. In addition to children’s early cognitive abilities, family characteristics such as the socioeconomic status and the home learning environment (HLE) are predictors of early child competencies. However, few studies outside the US and the UK have analyzed long-term effects of the early HLE on child development, simultaneously considering various explanatory factors. In this longitudinal study, data of 920 German children were obtained in kindergarten some 18 months before school entry (child mean age: 4;10). At this point, precursors of reading, spelling and mathematics were assessed. In addition, parents were asked to complete surveys on family characteristics. Child assessments were repeated with standardized measures of mathematical and literacy abilities at the end of Grade 1 and in the middle of Grade 4 (child mean age: 9;9), the final grade in German elementary schools. In Grade 4, teachers were also asked to provide their recommendation for children’s secondary school track (“Hauptschule” for lowest secondary school track, “Realschule”, or “Gymnasium” as highest secondary school track). HLE was not only a good predictor of early abilities, but also directly predicted competencies at the end of elementary school when precursors, former academic achievement and child and family characteristics were controlled for. In addition, children living in more favorable HLEs were more likely to be recommended for higher secondary school tracks by their teachers.     

Leveraging Sunken Investments in Communications Infrastructure: A Policy Perspective From the United States

Bridging the digital divide between information and technology haves and have-nots has waned from the top of the national policy agenda in the United States during a time in which the sunken investments of the 1990s need to be leveraged. A national information network now exists yet this infrastructure--largely hardware--needs to be continually modernized and parlayed with commitments to building human capacity, developing relevant content, and scaling socially beneficial technology applications, such as telemedicine, in order to optimize these initial multi-billion-dollar outlays. This article makes the case that sidestepping public-private initiatives aimed at accelerating digital opportunity is imprudent, given the mounting empirical evidence highlighting the payoffs of information and communications technologies, when properly integrated and applied, especially in enhancing the life chances of underserved Americans. Policy next steps should advance the goals of expanding universal service initiatives, including hastening broadband deployment to homes and learning institutions, and deepening programs which leverage the utility of the existing infrastructure, such as expanding human-capital development, producing relevant content, and innovating socially beneficial technology applications.

‘Do you want me to translate this in English or in a better Mandinka language?’: Unequal literacy regimes and grassroots spelling practices in peri-urban Gambia

This paper presents a comparative ethnographic analysis of two versions of a grassroots text in Mandinka language, one written by a non-formally educated man, the other a respelling by a formally educated urbanite. The analysis points at a crucial difference in spelling practices and inequality in literacy regimes, i.e., between established orthographic English literacy and the more creative, heterographic and emergent local language literacy. It is shown how English orthography affects local ideologies of literacy as well as Mandinka spelling practices itself, in greater or lesser extent, depending on the educational history of the speller.     

Socially shared metacognition of dyads of pupils in collaborative mathematical problem-solving processes

This study investigated how metacognition appears as a socially shared phenomenon within collaborative mathematical word-problem solving processes of dyads of high-achieving pupils. Four dyads solved problems of different difficulty levels. The pupils were 10 years old. The problem-solving activities were videotaped and transcribed in terms of verbal and nonverbal behaviours as well as of turns taken in communication (N = 14 675). Episodes of socially shared metacognition were identified and their function and focus analysed. There were significantly more and longer episodes of socially shared metacognition in difficult as compared to moderately difficult and easy problems. Their function was to facilitate or inhibit activities and their focus was on the situation model of the problem or on mathematical operations. Metacognitive experiences were found to trigger socially shared metacognition.
