Employing metasynthesis as a method, this study examined 52 empirical articles on culturally relevant and responsive science education in K‐12 settings to determine the nature and scope of complementarity between culturally responsive and inquiry‐based science practices (i.e., science and engineering practices identified in the National Research Council's Framework for K‐12 Science Education). The findings from this study indicate several areas of complementarity. Most often, the inquiry‐based practices Obtaining, Evaluating, and Communicating Information, Constructing Explanations and Designing Solutions, and Developing and Using Models were used to advance culturally responsive instruction and assessment. The use and development of models, in particular, allowed students to explore scientific concepts through families’ funds of knowledge and explain content from Western science and Indigenous Knowledge perspectives. Moreover, students frequently Analyzed and Interpreted Data when interrogating science content in sociopolitical consciousness‐raising experiences, such as identifying pollution and asthma incidences in an urban area according to neighborhood location. Specific inquiry‐based practices were underutilized when advancing culturally responsive science instruction, though. For example, Using Mathematics and Computational Thinking and Engaging in Argument from Evidence were infrequently encountered. However, culturally responsive engineering‐related practices were most often connected with these, and thus, represent potential areas for future complementarity, particularly as the United States embraces the Next Generation Science Standards. In considering innovative directions for advancing equitable science education, several possibilities are discussed in light of the findings of this study.© 2017 Wiley Periodicals, Inc.

Reflection in action research is a complex matter, as is action research itself. In recent years, complexity science has regularly been called upon in order to more thoroughly understand the complexity of action research. The present article investigates the benefits that complexity science may yield for reflection in action research. This article begins by explicating the sense in which the complexity of reflection in action research involves the role of values and existential knowledge in education. The gap between theory and practice is also explored. On the basis of a number of common features of complex systems (heterogeneous, open, dynamic, non-linear, adaptive, and co-adaptive), the sense in which reflection can be regarded as a complex system is discussed. To this end, the features of complex systems are translated into features of reflection in action research, which, in turn, are illustrated with examples from recent publications on reflection in action research. The aim of this analysis is to make reflection in action research more understandable and manageable. In line with this, it is argued that room for insecurity and unpredictability, combined with an explicit consideration of reflection as a complex system, contributes to the use of complexity as a stimulus for new learning.  相似文献

Curiosity is fundamental to scientific inquiry and pursuance. Parents are important in encouraging children’s involvement in science. This longitudinal study examined pathways from parental stimulation of children’s curiosity per se to their science acquisition (SA). A latent variable of SA was indicated by the inter-related variables of high school science course accomplishments, career interest, and skill. A conceptual model investigated parental stimulation of children’s curiosity as related to SA via science intrinsic motivation and science achievement. The Fullerton Longitudinal Study provided data spanning school entry through high school (N?=?118). Parental stimulation of curiosity at age 8 years comprised exposing children to new experiences, promoting curiosity, encouraging asking questions, and taking children to a museum. Intrinsic motivation was measured at ages 9, 10, and 13 years, and achievement at ages 9, 10, and 11 years. Structural equation modelling was used for analyses. Controlling for socio-economic status, parental stimulation of curiosity bore positive and significant relations to science intrinsic motivation and achievement, which in turn related to SA. Gender neither related to stimulation of curiosity nor contributed to the model. Findings highlight the importance of parental stimulation of children’s curiosity in facilitating trajectories into science, and relevance to science education is discussed.  相似文献
