An examination of artifacts provides insights into the goals, practices, and orientations of the persons and cultures who created them. Here, we analyze storybook texts, artifacts that are a part of many children's lives. We examine the stories in books targeted for 4–8-year-old children, contrasting the texts generated by Native American authors versus popular non-Native authors. We focus specifically on the implicit and explicit ‘epistemological orientations’ associated with relations between human beings and the rest of nature. Native authors were significantly more likely than non-Native authors to describe humans and the rest of nature as psychologically close and embedded in relationships. This pattern converges well with evidence from a behavioral task in which we probed Native (from urban inter-tribal and rural communities) and non-Native children's and adults' attention to ecological relations. We discuss the implications of these differences for environmental cognition and science learning.

This quasi-experimental study explores how student cumulative situational interest, short-term preference generated by particular conditions such as novel experiences can be developed into better individual interest, an enduring predisposition to engage in certain activity such as chemistry lessons. A continuous intervention of integrating novelty and aesthetic experience into teaching was used for the experimental group (n = 64) while another class of 105 students studying another course of physical science without the intervention of novelty and aesthetics served as a comparison group. The analysis of covariance comparing the two group students' pre- and post-test perceptions of learning science revealed that the experimental group outperformed the comparison group in their perceptions of interest, enjoyment, and aesthetics. The weekly assessment of student situational interest indicated that the experimental group students' situational interests were well maintained by two leading learning activities: demonstrations and hands-on experiments with novelty and aesthetic experience. The above results provide empirical evidence to support the theory of interest development, which proposes that the development goes through a cumulative and progressive procedure.

Dynamic visualizations can make unseen phenomena such as chemical reactions visible but students need guidance to benefit from them. This study explores the value of generating drawings versus selecting among alternatives to guide students to learn chemical reactions from a dynamic visualization of hydrogen combustion as part of an online inquiry unit. In prior research, generation has been more successful than selection in helping students distinguish among ideas to learn complex topics. However, selecting among perplexing alternatives may motivate learners to distinguish among ideas they might otherwise neglect. To test the value of selection for helping students distinguish ideas, this study contrasted complex selection (involving normative as well as non-normative ideas identified in prior research) from typical selection (involving images from the visualization). Results showed that all conditions improved student understanding and that typical selection was less effective than generation while complex selection was as successful as generation. In both generation and complex selection students revisited the visualization while learning, whereas revisiting was rare in typical selection. These results support the idea that distinguishing among common non-normative ideas is more valuable than distinguishing among images from the visualization. In addition, for students with low prior knowledge, both generation and complex selection had some advantages. Overall, the results suggest that students learning from complex visualizations could benefit from a combination of complex selection and generation.

The 39 preservice teachers (PSTs) who participated in this study were enrolled in a masters program for secondary science teacher certification. Initially they held broad ideas about teaching and learning gleaned from their own experiences. Guided by the program course work, some PSTs embraced the pedagogical approaches introduced in the program, applied them in their teaching, and reflected on the outcomes. Their reflections showed that they were focused on keeping all of their students interested in science and on student participation in the process of meaning-making. Some PSTs embraced the program goals but struggled to achieve them in teaching. Others focused on transmission of content and did not attempt to develop an environment of student agency. There were nine career-changer PSTs and most of them remained teacher-centered throughout the program. The implications of student- and teacher-centered approaches adopted by the PSTs and the rationales provided by them are discussed in the paper.

Nowadays, early science education is well-accepted by researchers, education professionals and policy makers. Overall, teachers’ attitudes and conceptions toward the science subject domain and science education influence their ways of teaching and engagement. However, there is a lack of research regarding factors that affect this engagement in pre-school years. The main assumption of this study is that teachers’ attitudes regarding science in pre-school can shape children's engagement in science and develop their scientific curiosity. Therefore, the main objectives of this study are to investigate the attitudes of pre-school teachers toward engaging in science and to explore their views about the nature of curiosity: who is a curious child and how can a child's natural curiosity be fostered? An extensive survey was conducted among 146 pre-school teachers by employing both qualitative and quantitative approaches. Results indicate that most of the participants believe that scientific education should begin in early childhood; very young children can investigate and take part in a process of inquiry; and scientific activities in pre-school can influence children's long-term attitudes toward science. Despite these views, most participants felt they did not possess sufficient scientific knowledge. Furthermore, participants expressed diverse opinions when asked to identify what constitutes curiosity, how the curious child can be identified and how a child's curiosity can be fostered. The research findings carry significant implications regarding how to implement scientific activities in pre-school, and how to encourage pre-school teachers to engage children in scientific activities in a way that will nurture their natural curiosity.

The purpose of this study is to use a comparative approach to scrutinize the common assumption that certain school science activities are theoretical and therefore particularly suited for engaging students with scientific ideas, whereas others are practical and, thus, not equally conducive to engagement with scientific ideas. We compared two school science activities, one (laboratory work) that is commonly regarded as focusing attention on artefacts that may distract students from central science concepts and the other (concept mapping) that is thought to make students focus directly on these concepts. We observed students in either a laboratory activity about real galvanic cells or a concept-mapping activity about idealized galvanic cells. We used a practical epistemology analysis to compare the two activities regarding students' actions towards scientific ideas and artefacts. The comparison revealed that the two activities, despite their alleged differences along the theory–practice scale, primarily resulted in similar student actions. For instance, in both activities, students interacted extensively with artefacts and, to a lesser extent, with scientific ideas. However, only occasionally did students establish any explicit continuity between artefacts and scientific ideas. The findings indicate that some of the problems commonly considered to be unique for school science practical work may indeed be a feature of school science activities more generally.

The Measure of Acceptance of the Theory of Evolution (MATE) was constructed to be a single-factor instrument that assesses an individual's overall acceptance of evolutionary theory. The MATE was validated and the scores resulting from the MATE were found to be reliable for the population of inservice high school biology teachers. However, many studies have utilized the MATE for different populations, such as university students enrolled in a biology or genetics course, high school students, and preservice teachers. This is problematic because the dimensionality and reliability of the MATE may not be consistent across populations. It is not uncommon in science education research to find examples where scales are applied to novel populations without proper assessment of the validity and reliability. In order to illustrate this issue, a case study is presented where the dimensionality of the MATE is evaluated for a population of non-science major preservice elementary teachers. With this objective in mind, factor analytic and item response models are fit to the observed data to provide evidence for or against a one-dimensional latent structure and to detect which items do not conform to the theoretical construct for this population. The results of this study call into question any findings and conclusions made using the MATE for a Hispanic population of preservice teachers and point out the error of assuming invariance across substantively different populations.
