This study used the construct of "lyricism" as an instructional practice to explore the identity connections and cognitive learning potential embedded in instruction in a culturally relevant context. Through a 5-week mixed methods study of students using the principles of lyricism (e.g., metaphor, double entendre, personification,…

The study explores how a complexity approach empowers science learning. A complexity approach represents systems as many interacting entities. The construct of micro-macro compatibility is introduced, the degree of similarity between behaviors at the micro- and macro-levels of the system. Seventh-grade students' learning about gases was studied…

The national efforts underway to include engineering in K-12 science education present a variety of new challenges, including how to prepare teachers to teach a new discipline. In this paper, we focus on elementary teachers and how they enter into "responsive teaching," in which they closely attend and meaningfully respond to students'…

Scholars argue that bridging students' backgrounds with canonical science is necessary for students of color by reducing incongruences between home and school and increasing the authenticity of science learning. However, science teachers often struggle with enacting culturally responsive pedagogies (CRP). This paper utilizes data from classroom…

Darwinian evolution is difficult to understand because of conceptual barriers stemming from intuitive ideas. This study examined understanding of evolution in 52 students (M = 14.48 years, SD = 0.89) before and after a guided field trip to a natural history museum and in a comparison group of 18 students (M = 14.17 years, SD = 0.79) who did not…

Situational interest is short-term interest that is linked to environmental factors in a particular situation. Previous studies have found that some science teaching techniques can be very effective in generating situational interest among students, but the reasons why these are effective remain unclear: Hands-on activities, for example, are known…

We report on research that explores students' literacy practices in six Norwegian primary school science classrooms during integrated science-literacy instruction. The study combines observational video data and interview data to examine students' encounters with and use of text, along with their views and experiences related to science and…

We investigated a 2.5-year professional development effort designed to support practicing science and mathematics teachers in understanding equity and enacting equitable practices. Our purpose was to inform the research base on effective equity professional development, toward the goal of better supporting science and mathematics teachers in…

Although teacher educators have achieved some success in improving teachers' understanding of the nature of science (NOS), helping teachers teach NOS has proved a much greater challenge. Currently, there are few examples in the literature of teachers who effectively teach NOS, and fewer still that rely on student outcomes as a measure of teachers'…

The characterization of students' cognitive biases is of central importance in the development of curriculum and teaching strategies that better support student learning in science. In particular, the identification of shortcut reasoning procedures (heuristics) used by students to reduce cognitive load can help us devise strategies to foster the…

The purpose of this project was to investigate the effects of virtual versus physical manipulation using a simulation-based laboratory activity (SBL) and a microcomputer-based laboratory activity (MBL). Both the SBL and the MBL used computers to collect, graph, and analyze data. A major difference was that the MBL allowed the students to…

Framed in theories of social semiotics, this multiple case study describes and categorizes the actional-operational modes used by three middle school earth science teachers throughout the course of one school year. Data included fieldnotes, photographs, and video recordings of classroom instructions as well as periodic interviews with the…

Whole-class discussion is a common instructional approach used by secondary science teachers. When orchestrated well, such an approach can provide students with opportunities to engage in extensive science talk with the benefit of teacher guidance and feedback. Our study investigated teachers' approaches to discussion during the piloting of an…

Although studies have documented teachers' growth in assessing science resulting from professional development or science methods courses, little attention has been given to growth while being prepared to assess a linguistically diverse student population. In this study, the growth of 11 secondary science preservice teachers is documented by…

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…
