This article stems from a professional inquiry carried out by two secondary science curriculum and learning facilitators, as part of a continual strengthening of their facilitating practice. The article describes the reflections of several secondary science teachers as they progress their understanding of the science capabilities, and make changes…

Precipitation of barium phosphate from aqueous solutions of a barium salt and a phosphate salt forms the basis for a number of conclusions drawn in general chemistry. For example, the formation of a solid white precipitate is offered as evidence that barium phosphate is insoluble. Furthermore, analysis of the supernatant is used to illustrate the…

A theoretical framework is an important component of a research study. It grounds the study and guides the methodological design. It also forms a reference point for the interpretation of the research findings. This paper conceptually examines the process of constructing a multi-focal theoretical lens for guiding studies that aim to accommodate…

The 2008 science curriculum for Wales marked a landmark change in the way teachers planned and delivered science in primary schools. It was at the vanguard of the more pupil-centred style of curriculum planning and pedagogy that supported the dual initiatives of improving the quality of assessment for learning and thinking skills in all schools.…

In 1997, developmental biologist Michael Richardson compared his research team's embryo photographs to Ernst Haeckel's 1874 embryo drawings and called Haeckel's work "noncredible". "Science" soon published "Haeckel's Embryos: Fraud Rediscovered," and Richardson's comments further reinvigorated criticism of Haeckel by…

The curriculum module described in this article addresses the global issue of ocean acidification (OA) (Feely 2009; Figure 1). OA is a harmful consequence of excess carbon dioxide (CO[subscript 2]) in the atmosphere and poses a threat to marine life, both algae and animal. This module seeks to teach and help students master the cross-disciplinary…

The integration of science and agriculture has been discussed since the inception of agricultural education. However, the standards-based focus in public secondary education and changing climate of agriculture has brought science integration back to the forefront. Though research has indicated that the integration of science into agricultural…

Science education involves students learning explanations of natural phenomena which are neither obvious nor intuitive. Generally, they have been arrived at and refined by years of dedicated inquiry on the part of large scientific communities. At the same time, these phenomena often concern the objects of everyday experience regarding which…

In this paper, we analyze the science activities offered at 7th grade in the Turkish science and technology curriculum along with addressing the curriculum's original intent. We refer to several science education researchers' ideas, including Chinn & Malhotra's (Science Education, 86:175--218, 2002) theoretical framework and Edelson's (1998)…

Recent research on teacher professional development (PD) underscores the importance of the coherence of PD with standards, curriculum, and assessment. Teachers' judgments of the coherence of PD with larger system goals influence their decisions about what ideas and resources they appropriate from PD. Little research, however, has examined how…

There is considerable evidence suggesting that students in rural schools lag behind their city counterparts in measures of science literacy and attitude to science learning. If we are to address this situation we need to build as full a picture as we can of the key features of what is a complex and varied rural schooling context. In this article…

Prior research has mainly focused on what makes professional development effective from the program design perspective. However, there is a lack of understanding about what teachers need for improvement in the context of educational reforms and curricular changes. This study used the pedagogical content knowledge framework to examine teachers'…

The purpose of this study was to identify evidence in student work of teachers' uptake of educative features in educative curriculum materials. These are features in curriculum materials designed with the specific intent of supporting teacher learning and enactment. This study was prompted by previous work on educative curriculum materials and the…

Over the past several decades, numerous reports have been published advocating for changes to undergraduate science education. These national calls inspired the formation of the National Academies Summer Institutes on Undergraduate Education in Biology (SI), a group of regional workshops to help faculty members learn and implement interactive…

Twenty-first-century biology rejects genetic determinism, yet an exaggerated view of the power of genes in the making of bodies and minds remains a problem. What accounts for such tenacity? This article reports an exploratory study suggesting that the common reliance on Mendelian examples and concepts at the start of teaching in basic genetics is…
