Spoken Language and Mathematics     

Andrea Raiker 《Cambridge Journal of Education》2002,32(1):45-60

Teachers and learners use spoken language in the three part mathematics lesson advocated by the National Numeracy Strategy (NNS). This document recognises the importance of language by emphasising 'the correct use of mathematical vocabulary' in the raising of standards. Research into the use of vocabulary in science suggests that the use of scientific words does not necessarily demonstrate conceptual understanding. Pupils and teachers appear to ascribe different meanings to scientific words because of their relative positions on the novice/expert continuum. To explore whether mathematical words could cause similar problems, data collected from six groups of teachers and learners was subjected to discourse analysis to provide evidence of how spoken language was used and how meaning and understanding were achieved. The implications of the findings on the use of language by both teachers and learners in the NNS mathematics lesson, including vital areas for reflection by teachers, are fully considered.  相似文献   

Professional development design considerations in climate change education: teacher enactment and student learning     

Andrea Drewes  Joseph Henderson  Chrystalla Mouza 《International Journal of Science Education》2018,40(1):67-89

Climate change is one of the most pressing challenges facing society, and climate change educational models are emerging in response. This study investigates the implementation and enactment of a climate change professional development (PD) model for science educators and its impact on student learning. Using an intrinsic case study methodology, we focused analytic attention on how one teacher made particular pedagogical and content decisions, and the implications for student’s conceptual learning. Using anthropological theories of conceptual travel, we traced salient ideas through instructional delivery and into student reasoning. Analysis showed that students gained an increased understanding of the enhanced greenhouse effect and the implications of human activity on this enhanced effect at statistically significant levels and with moderate effect sizes. However, students demonstrated a limited, though non-significant gain on the likely effects of climate change. Student reasoning on the tangible actions to deal with these problems also remained underdeveloped, reflecting omissions in both PD and teacher enactment. We discuss implications for the emerging field of climate change education.  相似文献   

Developing a measure to understand young children’s Internet cognition and cyber-safety awareness: a pilot test

Abstract

Advancements in technology have increased preschool children’s access to the Internet. Very little research has been conducted to identify pre-school-aged children’s understandings of the Internet and ramifications of being ‘online’. Without an understanding of children’s thinking about the Internet, it is difficult to provide age- and pedagogically appropriate cyber-safety education. This study developed and pilot-tested an interview schedule that focuses on the Internet thinking and cyber-safety awareness of Australian children aged 4–5 years. The schedule is informed by sociocultural theory, cyber-safety education research and approaches for researching with young children. The schedule shows potential to elicit children’s understandings of the Internet and cyber-safety awareness. Adjustments are required to allow more contextualised responses from children.  相似文献   

Noddings’ “Critical Lessons” May be Particularly Critical at the Elementary Level     

Andrea S. Libresco 《理论付诸实践》2018,57(4):281-288

This article explores Nel Noddings’ conception of pedagogical neutrality and its meanings and implications for classroom conversations, particularly at the elementary grade levels. It examines the selection of issues for classroom discourse and the importance of teachers purposefully exposing students to arguments and data with which they may be less familiar, especially in more polarized settings. The piece also discusses the extent to which younger students can grapple with controversial issues, and the arguments for and against elementary teachers sharing their views with their students. The piece concludes with examples of, and guidelines for, facilitating effective discussions of controversial issues at the primary and intermediate elementary levels.  相似文献   

The same in German as in English? Investigating the subject-specificity of teaching quality

Teaching quality often is assumed to be a personal and stable characteristic of teachers. Whether this is true has scarcely been investigated empirically. In this study the extent to which value-added scores of teachers teaching German and English as a foreign language (EFL) to the same class remain consistent across subjects was investigated. Then, the consistency of two teaching quality dimensions—classroom management and motivational support—across subjects was explored. A sample consisting of 25 classes with 548 students to whom German and EFL were taught by the same teacher was analyzed using multivariate multilevel models and generalizability theory. The results showed that the value-added scores were highly correlated across subjects. While there was hardly any subject-dependent variance in classroom management, there was substantial subject-dependent variance in motivational support. The results indicate that it is important to conduct further studies on the situational and contextual factors that might influence teaching quality to gain a more comprehensive picture regarding the consistency of teaching quality across various conditions.  相似文献

Embracing the complexity of inclusive science classrooms: Professional development through collaboration     

Lori Lyman DiGisi  Andrea Nix  Karen Daniels  Leslie Kramer  Susan Cyr 《Research in Science Education》1999,29(2):247-268

There are no panaceas and no shortcuts. Man is an amphibious being who lives simultaneously or successively in several universes: in the world of matter, the world of mind, the world of spirit; in the individual world and in the social world; in the homemade universe of his own artifacts, institutions, and imaginings, and in the given, the God-made universe of nature and grace. In the very nature of things none of the major problems confronting such a being can possibly be a simple problem. Those who seek simple solutions for complex problems may have the best of intentions; but unfortunately there is an original sin of the intellect in our habit of arbitrary oversimplification. Those who act without taking precautions against this vice of their intellectual nature doom themselves and their fellows to perpetual disappointment. (Aldous Huxley, 1953, p. 1.)  相似文献

Reduction of water evaporation in polymerase chain reaction microfluidic devices based on oscillating-flow   总被引：1，自引：0，他引：1

Producing polymeric or hybrid microfluidic devices operating at high temperatures with reduced or no water evaporation is a challenge for many on-chip applications including polymerase chain reaction (PCR). We study sample evaporation in polymeric and hybrid devices, realized by glass microchannels for avoiding water diffusion toward the elastomer used for chip fabrication. The method dramatically reduces water evaporation in PCR devices that are found to exhibit optimal stability and effective operation under oscillating-flow. This approach maintains the flexibility, ease of fabrication, and low cost of disposable chips, and can be extended to other high-temperature microfluidic biochemical reactors.  相似文献
