Student understanding of biological representations has not been well studied. Yet, we know that to be efficient problem solvers in evolutionary biology and systematics, college students must develop expertise in thinking with a particular type of representation, phylogenetic trees. The purpose of this study was to understand how undergraduates…

We focused on young, low-income, African American children in first- to third-grade classrooms where they experienced varied forms of interactive, participatory, and dialogic pedagogy in the context of yearlong, integrated science-literacy instruction. Using conversations that started around children's own science journals, which were an important…

This study attends to the possibilities of analyzing students' writings at a lexicogrammatical level in terms of their use of linguistic resources, and the insights afforded by this approach into the challenges students faced when they employed the language of school science related to the phenomenon of expansion. For the purpose of this study,…

As the global economic crisis continues, sustaining the United States' position as a leader in research and development is a top concern of policy makers. Looking to increase the number of students pursuing degrees in STEM (science, technology, engineering, and mathematics), calls for improved mathematics and science education abound. We completed…

This article examines the use and role of the term "experiment" in science teacher education as described by teacher students. Data were collected through focus group interviews conducted at seven occasions with 32 students from six well-known Swedish universities. The theoretical framework is a sociocultural and pragmatist perspective on language…

Curriculum materials are important resources with which teachers make pedagogical decisions about the design of science learning environments. To become well-started beginning elementary teachers capable of engaging their students in inquiry-based science, preservice elementary teachers need to learn to use science curriculum materials…

This review examines 105 empirical studies that investigate students' views of the nature of science (VNOS), effects of curricular interventions on changing students' VNOS, and relations between VNOS and demographics, majors, and learning of science. The reviewed studies can be categorized into three theoretical frameworks: the unidimension, the…

It has been argued that learning science may be complicated, and even compromised, when students hold worldviews that may seem at odds with what is presented in science lessons. In particular, in some parts of the world, there has been considerable concern that students from particular religious backgrounds may reject some science teaching if…

As part of becoming scientifically literate, students should come to appreciate epistemic aspects of science. Little research has been conducted on elementary students' epistemological beliefs specific to science education. This study offers insights into third-grade students' epistemological beliefs while paying attention to the intersection of…

Within the framework of social cognitive theory, we examined the motivation of students (14-16 years old) to learn science in their introductory science courses. The students responded to a questionnaire about their intrinsic motivation, self-efficacy, and self-determination. The students also wrote essays about their motivation, and individual…

Earth Systems Science (ESS) is emerging rapidly as a discipline and is being used to replace the older earth science education that has been taught as unrelated disciplines--geology, meteorology, astronomy, and oceanography. ESS is complex and is based on the idea that the earth can be understood as a set of interacting natural and social systems.…

In both formal and informal settings, not only science but also views on the nature of science are communicated. Although there probably is no singular nature shared by all fields of science, in the field of science education it is commonly assumed that on a certain level of generality there is a consensus on many features of science. In this…

Teaching nature of science (NOS) is beginning to take root in science education in China. This exploratory study interviewed 24 science teacher educators from economically developed parts of China about their conceptions of teaching NOS to prospective science teachers. Five key dimensions emerged from the data. This paper focuses on the dimension…

This 3-year longitudinal study explores the evolving beliefs of five prospective secondary science teachers in a university preparation program from recruitment through their first year in the classroom. As an interpretive qualitative study, data were collected through semistructured interviews and an array of artifacts. The data sources were used…

Low teacher self-efficacy is an important factor constraining the teaching of science at the elementary level. This study was designed to investigate the effectiveness of particular sources of efficacy information for enhancing the science teaching self-efficacy of practicing elementary teachers. Twelve teachers participated in an intervention…
