Developing a Graduate Level Science Education Course on the Nature of Science

The purpose of this report is to outline our experiences designing and teaching a course on the nature of science to science education graduate students. By addressing questions related to the creation of a new university course, the design of the course syllabus, and the transformation of the syllabus into instruction, we hope to make our craft knowledge more accessible to others who create such courses.     

Reconceptualizing the Nature of Science for Science Education

Two fundamental questions about science are relevant for science educators: (a) What is the nature of science? and (b) what aspects of nature of science should be taught and learned? They are fundamental because they pertain to how science gets to be framed as a school subject and determines what aspects of it are worthy of inclusion in school science. This conceptual article re-examines extant notions of nature of science and proposes an expanded version of the Family Resemblance Approach (FRA), originally developed by Irzik and Nola (International handbook of research in history, philosophy and science teaching. Springer, Dordrecht, pp 999–1021, 2014) in which they view science as a cognitive-epistemic and as an institutional-social system. The conceptual basis of the expanded FRA is described and justified in this article based on a detailed account published elsewhere (Erduran and Dagher in Reconceptualizing the nature of science for science education: scientific knowledge, practices and other family categories. Springer, Dordrecht, 2014a). The expanded FRA provides a useful framework for organizing science curriculum and instruction and gives rise to generative visual tools that support the implementation of a richer understanding of and about science. The practical implications for this approach have been incorporated into analysis of curriculum policy documents, curriculum implementation resources, textbook analysis and teacher education settings.     

Defining mission statements in higher education: Towards a genre perspective

Mission statements provide educational institutions with the legitimacy to market and promote services through positive statements. This study applied genre analysis to examine the function of promotional rhetoric in top 100 international universities' mission statements. Bhatia's rhetorical moves of promotional genre was triangulated with Pearce and David's components for mission-writing. It was seen that international universities rely on promotional rhetorical moves to articulate their self-concept and services. Moreover, universities actively compete against each other to secure a high position in the international ranking lists. This ensures that they obtain additional incentives that help them gain economic stability and build a reputation. Promotional genre has become a practiced culture in the professional discourse community of higher education. Hence, there is a need to allow mission statements genre membership. We suggested a genre model that can be taught and used for writing mission statements. The most recurrent moves employed suggest that the communicative purpose for mission-writing used by international universities is to target the international market and build a public image to reel in more students, thereby improving their financial status while ensuring a good reputation. Based on this study, institutions can get guidance on designing and drafting effective mission statements.     

The interfaculty graduate environmental sciences program of the American University of Beirut: an ESD initiative in the Arab World

The American University of Beirut’s Interfaculty Graduate Environmental Sciences Program was launched in 1997 as a means of addressing salient issues on the environment and development in Lebanon and the Arab World using an interdisciplinary approach. The programme adopts a student-centred learning approach and aims to develop critical and systems thinking skills to produce socially and environmentally conscious leaders and agents of change in the Arab World. In this paper, we provide an evaluation of the programme’s ESD dimensions using the criteria of interdisciplinarity, local relevance and competence-based learning. This is followed by a critical analysis of the programme’s potential for use as a model in the Arab World. We find that, while the model may be useful in providing inspiration and a good practice case, its transfer “as is” to institutions of higher education in the Arab World or even in Lebanon is unlikely, and perhaps undesirable, in view of the inherently diverse nature of Arab universities.     

An Ethnographic Study of the Computational Strategies of a Group of Young Street Vendors in Beirut

This study examines the computational strategies of ten young street vendors in Beirut by describing, comparing, and analyzing the computational strategies used in solving three types of problems in two settings: transactions in the workplace, word problems, and computation exercises in a school-like setting. The results indicate that vendors' use of semantically-based mental computational strategies was more predominant in transactions and word problems than in computation exercises whereas written school-like computational strategies were used more frequently in computation exercises than in word problems and transactions. There was clear evidence of more effective use of logico-mathematical properties in transactions and word problems than in computation exercises. Moreover, the success rate associated with each of transactions and word problems was much higher than that associated with computation exercises.This revised version was published online in September 2005 with corrections to the Cover Date.     

非政府组织在天文学科普方面的作用

古代伊朗科学家曾对科学,特别是天文学做出过重大贡献。当代的伊朗科学家继承了这一传统,并致力于向公众传播科学。21世纪初,由一批科学家、热心科学传播的社会人士和私营企业组成的非政府组织积极筹建马什哈德天文馆、科学中心等科普场馆。本文通过这一案例,讨论了非政府组织在科普场馆建设和科学传播中的作用、问题和可行性,并介绍了马什哈德天文学会为此采取的相应对策。
