Socioscientific issues via controversy mapping: bringing actor-network theory into the science classroom with digital technology     

Mark Elam  Anne Solli  Åsa Mäkitalo 《Discourse: Studies in the Cultural Politics of Education》2019,40(1):61-77

ABSTRACT

What are the current challenges and opportunities for bringing actor-network theory (ANT) into issues-based science education? This article discusses experiences gained from introducing an educational version of ANT deploying digital technology into an upper secondary school science class. This teaching innovation, called controversy mapping, has been pioneered in different contexts of higher education before being adapted to school education. Experimenting with controversy mapping in a Swedish science class raised both conceptual and practical issues. These centre on: (1) how ANT-inspired controversy mapping redesigns the citizenship training enacted by institutionalized approaches to issues-based education as socioscientific issues (SSI); (2) how controversy mapping reconfigures the interdisciplinarity of issues-based science education; and (3) how controversy mapping displaces scientific literacy and knowledge of the nature of science as guiding concerns for teaching in favour of new preoccupations with digital literacy and digital tools and methods as contemporary infrastructures of free and open inquiry.  相似文献   

Financing constraints and corporate investment： an empirical analysis of china＇s manufacturing firms     

KONG Yu WEI Feng 《重庆大学学报(英文版)》2005,4(3):170-174

With the measurement of dividend payout ratio, logistic regression index value and the firm size financing constraints, this paper investigated the investment behavior of China＇s manufacturing firms over the period from 1998 to 2003, and the relationship between financing constraints and corporate investment using the OLS regression method. The empirical evidence shows that there are certain extent financing constraints in China＇s manufacturing firms, but the results are different with different variables to measure the financing constraints.  相似文献

合并大学校区分馆建设与发展面临的问题和对策     

张明霞 《昆明师范高等专科学校学报》2004,26(2):85-88

合并大学校区面临的主要问题是合并大学校园分散所带来的交通不便，以及资源较少、服务手段落后和管理不畅通。校区分馆首先应明确其功能定位，制定发展规划，在此基础上开展诸如文献资源配置等各项建设。在建设和发展中需要特别处理好总馆与分馆在不同时期的管理关系，注重建立数字化信息服务平台，拓宽服务手段，实行校区专业分馆的“学科馆员制”，据此构建合并大学较完善的全校性的文献服务保障体系。  相似文献

Learning and engagement through natural history museums*     

Tamjid Mujtaba  Martin Lawrence  Mary Oliver  Michael J. Reiss 《Studies in Science Education》2018,54(1):41-67

This review examines how natural history museums (NHMs) can enhance learning and engagement in science, particularly for school-age students. First, we describe the learning potential of informal science learning institutions in general, then we focus on NHMs. We review the possible benefits of interactions between schools and NHMs, and the potential for NHMs to teach about challenging issues such as evolution and climate change and to use digital technologies to augment more traditional artefacts. We conclude that NHMs can provide students with new knowledge and perspectives, with impacts that can last for years. Through visits and their on-line presence, NHMs can help students see science in ways that the school classroom rarely can, with opportunities to meet scientists, explore whole topic exhibitions, engage with interactive displays and employ digital technologies both in situ and to support learning in the school science classroom. Although these interactions have the potential to foster positive cognitive, affective and social outcomes for students, there is a lack of reliable measures of the impact of NHM experiences for students. Opportunities to foster relationships between NHM staff and teachers through professional development can help articulate shared goals to support students’ learning and engagement.  相似文献
