关于加强电大实践性教学的思考

实践教学是电大培养应用型人才的关键环节,也是电大教育中的一个难点。针对目前实践教学体系不够完善、实践教学师资相对匮乏、实践教学基地不够稳定、实践教学管理不够严密等状况,电大要制定明确的实践教学目标、完善实践教学体系、构建“双师型”教师队伍、加强实践基地建设、改革实践教学的评价方法,以培养社会欢迎的应用型人才。     

The effect of language specific factors on early written composition: the role of spelling,oral language and text generation skills in a shallow orthography

Spelling skills have been identified as one of the major barriers to written text production in young English writers. By contrast oral language skills and text generation have been found to be less influential in the texts produced by beginning writers. To date, our understanding of the role of spelling skills in transparent orthographies is limited. The current study addressed this gap by examining the contribution of spelling, oral language and text generation skills in written text production in Italian beginner writers. Eighty-three children aged 7–8 years participated in the study. Spelling, lexical retrieval, receptive grammar, and written sentence generation and reformulation skills were assessed and children were asked to write a text on a set topic. A factor analysis revealed that the children’s written text production was captured by three factors: productivity, complexity and accuracy. In contrast to results from children learning to write in opaque orthographies, such as English, this study showed that receptive grammar and written sentence generation skills accounted for significant variance in measures of productivity, complexity and accuracy in Italian children’s written text production. Spelling skills contributed to text accuracy and quality and explained more variance than receptive grammar in microstructural accuracy. By contrast, oral grammatical skills explained more variance in text quality than spelling. The current study shows the differential impact of language systems, such as Italian, on written text production. Implications for assessment and instruction are outlined.     

Towards powerful learning environments for the acquisition of problem-solving skills

It is generally agreed that acquiring thinking and problem-solving skills is nowadays a primary objective of general education. Responding appropriately to this challenge requires an answer to the following questions: 1. what does the acquisition of problem-solving skills involve, and 2. how can those abilities be fostered through systematic instruction? This contribution describes a four-step model of skilled problem-solving processes, and gives an overview of three major categories of cognitive skills involved in competent problem solving, namely, the flexible and integrated application of domain-specific knowledge, of heuristic methods, and of metacognitive skills. Furthermore, a framework is presented for the design and elaboration of powerful teaching-learning environments in which such problem-solving skills can be acquired efficiently. Two basic ideas underlying this model are: the view of learning as a constructive process, and the idea of cognitive apprenticeship as an effective and appropriate method for learning and teaching. Finally, some recent research findings supporting the educational significance of the framework are briefly reviewed.     

铁基PbO2电极的电沉积制备和表征

采用电沉积方法制备PbO2/Fe电极,研究了电镀液配方、电沉积温度、电流密度、添加剂以及底层(SnO2 Sb2O3)的制备对电极外观、电极的导电性能和使用寿命的影响.采用正交实验法得出了制备铁基PbO2电极的最佳工艺条件:先在低温40℃、大电流密度55mA/cm2条件下电沉积2h制备α-PbO2底层,而后在高温70℃、小电流密度35mA/cm2条件下沉积4h制备β-PbO2.
