Early Childhood Education in Societal Context: Teachers in Three Countries Speak About Early Childhood Education

Building on the cross-cultural patterns and systems research as well as social constructivism, in-depth interviews were conducted with key informant early childhood teachers in three regions with similar characteristics in Sweden, Russia, and in the United States. Inductive analyses revealed differences in responses among Swedish, Russian and American informants related to the macro-, meso-, and micro-levels of societal system. United States teacher informants had a great number of separate topic comments and distributed them more evenly across all levels than did Russian and Swedish teacher informants who had more emphasis at the meso level. United States and Russian teacher informants discussed the lack of societal support for young children and their families, while Swedish teacher informants seemed to almost take this support for ranted. United States teacher informants suggested that early childhood programs were important in developing support networks among parents, while Russian teacher informants often gave information to parents and Swedish teachers spoke about mutually sharing information. United States teacher informants desired both strict rules with strong academic content and extension of the child's initiations through play; they emphasized activities and materials. Swedish teachers discussed a child- centered approach to social learning and creativity and desired to be with children rather than do activities with them. Russian teacher informants emphasized the importance of obedience, aesthetic education, and preparation for school and the labor of the larger society. These study outcomes deepen understanding about the multidemensional relationships between early childhood programs and societal contexts in which they are embedded, and they suggest alternative approaches to working with young children and their families.     

From Students to Teachers: Investigating the Science Teaching Efficacy Beliefs and Experiences of Graduate Primary Teachers

Research in Science Education - The science achievement of primary students, both in Australia and abroad, has been the subject of intensive research in recent decades. Consequently, much research...     

Evaluating a digital library self-archiving service: The BDBComp user case study

In this article, we present an overview of a self-archiving service for the Brazilian Digital Library of Computing (BDBComp) and describe a user experiment conducted to evaluate it. This experiment involved several potential real users, including computer science graduate students and professors, and archivists/librarians. The results of this study and their implications for similar services are described and analyzed, following sound statistical principles, which can serve as a basis for other similar studies. These results and their analysis indicate that we have successed in building a usable, efficient and learnable self-archiving service, properties which are essential to bring users to the system.     

Waste in education: the potential of materiality and practice

This article explores how waste materials and waste practices figure in education, pointing to educational potentials of waste which have hitherto received little consideration in environmental and sustainability education practice and research. Building on empirical research on waste education in Danish schools and preschools, we discuss how an empirical and theoretical focus on waste as material and on waste practices moves beyond conventional approaches to waste in education. Seeking to overcome the shortcomings of habitual-behavioural and rational action approaches, we argue for an approach to waste education which encourages pupils to explore the socio-material aspects and trajectories of waste practices and waste materials.     

Attitudes towards Science Learning among 10th‐Grade Students: A qualitative look

The twenty‐first century is characterized by multiple, frequent and remarkable scientific advancements, which have a major effect on the decisions that govern everyday life. It is therefore vital to give proper comprehensive scientific education to the population and provide it with the right tools for decision‐making. This in turn requires that we foster a positive attitude among students towards science studies and encourage them to choose sciences as their major subjects. The following study examines 10th‐grade high school students in an attempt to understand and document the influential factors underlying their attitudes towards science studies. The study is conducted through a qualitative research methodology, gathering data based on interviews. This methodology exposes the students’ feelings, views and beliefs, and explores the characteristics of the factors influencing students’ attitudes. Of these factors, we found the most significant for high school students to be interpersonal interaction between teacher and student, the relevance and authenticity of the topics being studied, and the diversity of the teaching methods. We therefore suggest that these three elements should be given particular emphasis by teachers and teacher educators.     

中国煤炭需求弹性估算:时间波动与区际差异

需求弹性是经济学中的基础概念,也是我国煤炭市场化进程中的重要研究对象.不同于以往的宽泛研究,本文分别从国家维度、时间维度和区域维度对1995-2010年间的我国煤炭需求弹性展开系统化研究.基于面板数据模型的研究发现全国煤炭需求的价格弹性为0.59,煤炭在所考察期间总体呈现出刚性需求现象,但基于截面数据的回归结果显示各考察年份的煤炭需求弹性为负值且存在着较大的时间波动,而各区域时间序列的回归结果表明煤炭需求弹性的区际差异: 煤炭主产地其值为负,消费地其值为正.分析发现以国家维度和时间维度的研究结论相互矛盾,而以区域维度的研究结果更加科学合理,具有更为可靠的理论和现实指导意义.     

Project ASTER III: A Model for Teacher Professional Development Integrating Science Museum Exhibits with State and National Science Education Content Standards

Abstract This article describes Project ASTER III (Active Science Teaching Encourages Reform), a science professional development program for early elementary teachers, which is based on the premise that people learn best by doing. Very few professional development programs focus on early childhood teacher development and how best to integrate informal science centers into teaching. In ASTER III, development teams—consisting of university scientists, science educators, K‐3 teachers, and educators from a hands‐on science museum—developed 5E lesson plans aligned with the Ohio Academic Content Standards and the National Science Education Standards in conjunction with the museum’s exhibits. This study explores the impact of the ASTER III model on teacher perceptions about the role and effect informal science museum visits have on subsequent teaching and student learning.     

A Conceptual Characterization of Online Videos Explaining Natural Selection

Educational videos on the Internet comprise a vast and highly diverse source of information. Online search engines facilitate access to numerous videos claiming to explain natural selection, but little is known about the degree to which the video content match key evolutionary content identified as important in evolution education research. In this study, we therefore analyzed the content of 60 videos accessed through the Internet, using a criteria catalog with 38 operationalized variables derived from research literature. The variables were sorted into four categories: (a) key concepts (e.g. limited resources and inherited variation), (b) threshold concepts (abstract concepts with a transforming and integrative function), (c) misconceptions (e.g. that evolution is driven by need), and (d) organismal context (e.g. animal or plant). The results indicate that some concepts are frequently communicated, and certain taxa are commonly used to illustrate concepts, while others are seldom included. In addition, evolutionary phenomena at small temporal and spatial scales, such as subcellular processes, are rarely covered. Rather, the focus is on population-level events over time scales spanning years or longer. This is consistent with an observed lack of explanations regarding how randomly occurring mutations provide the basis for variation (and thus natural selection). The findings imply, among other things, that some components of natural selection warrant far more attention in biology teaching and science education research.
