This article describes the substance, structure, and rationale of a learning progression in genetics spanning kindergarten through twelfth grade (K-12). The learning progression is designed to build a foundation towards understanding protein structure and activity and should be viewed as one possible pathway to understanding concepts of genetics…

This study explores five minority preservice teachers' conceptions of teaching science and identifies the sources of their strategies for helping students learn science. Perspectives from the literature on conceptions of teaching science and on the role constructs used to describe and distinguish minority preservice teachers from their mainstream…

This study based on a theoretical framework of three main environmental perspectives in the human-nature relationship (anthropocentrism, biocentrism and ecocentrism), aimed to identify their incidence in teachers involved with environmental projects when confronted with diverse environmental issues. 60 teachers drawn from four school cycles in…

Science education research has examined the benefits of coteaching for learning to teach in elementary and secondary school contexts where coteachers bring variable levels of experience to the work of coteaching. Coteaching as a pedagogical strategy is being implemented at the university level but with limited research. Drawing from the field of…

A collaborative curriculum development project was set up to address the lack of good examples of teaching about ideas and evidence and the nature of science encountered by student teachers training to teach in the age range 11-16 in schools in England. Student and teacher-mentor pairs devised, taught and evaluated novel lessons and approaches.…

This paper reports research from a three-year Australian science teacher professional learning project, the Science Teaching and Learning (STaL) Project, in which groups of science teacher participants (across years K-12) worked with academics over a one-year period as teacher researchers. Through reflecting on their experiences within the STaL…

Most studies indicate primary students' attitudes towards and interest in science decline as they progress into the secondary years. Longitudinal qualitative research exploring this phenomenon is rare as is research which focuses on the students' voice as they cross the interface. In this study multiple qualitative data sources, supported by a…

Background: In this era of rapid technical advancement, there are growing debates around the idea of nanotechnology, which are both timely and controversial. Nanotechnology materials are being utilized in our daily lives in many ways, often without consumer knowledge. Due to the explosion of nanotechnology applications, there is a necessity to…

Working memory capacity has been shown to be an important factor in controlling understanding in the sciences. Attitudes related to studies in the sciences are also known to be important in relation to success in learning. It might be argued that if working memory capacity is a rate controlling feature of learning and success in understanding…

Many of the explanations for girls' disinterest in physics focus on the role of the educational system in creating this situation. Here, we use evidence from free-choice science learning settings to study if this lack of interest is also expressed in non-school settings. Three sets of self-generated questions raised by children, adolescents and…

Analyzes the pedagogic functions of visual images included in school science textbooks and daily press articles about science and technology. Indicates that the science textbooks (a) use 10 times more images, (b) use more images so as to familiarize their readers with the specialized techno-scientific content and codes, and (c) tend to create a…

Studies students aged 12 to 14 years (n=217) representing a wide ability range. Analyzes the responses of participants to the dissolution of a solid in both cold and warm water. Findings have implications for the teaching of all science theory but especially for conveying the purpose of models and the process of modeling. (Contains 29 references.)…

Outlines four ways in which the relationship between the learner and everyday technology might be analyzed using early childhood studies as examples. The four individual-technology relationships are described as affording, anchoring, distributing, and appropriating. (Contains 58 references.) (DDR)

Reports on the evaluation of a three-year curriculum initiative introducing technology education through a learner-centered, problem solving and collaborative approach. Draws attention to the critical impact the project had on the pedagogy of teachers. (DDR)

Points out that technology education in New Zealand provides an opportunity for societal issues to have equal space with technological capability and knowledge. There is a need for a teaching approach to engage in liberating technological literacy. (Contains 19 references.) (DDR)
