Recently, the relationship between identity and learning has come front and center in discussions about how to design successful learning environments for youth who struggle in mainstream institutions. In this essay, I explore the role identity development plays in constructing learning environments for traditionally marginalized youth. While I agree with DeGennaro and Brown on the importance of identity development for learning, I stretch the relationship between these two constructs in several ways: First, I will argue that how we define “technology” and what that means for marginalized
Argumentation has become an increasingly recognized focus for science instruction---as a learning process, as an outcome associated with the appropriation of scientific discourse, and as a window onto the epistemic work of science. Only a small set of theoretical conceptualizations of argumentation have been deployed and investigated in science education, however, while a plethora of conceptualizations have been developed in the interdisciplinary fields associated with science studies and the learning sciences. This paper attempts to review a range of such theoretical conceptualizations of
Conceptual change views of teaching and learning processes in science, and also in various other content domains, have played a significant role in research on teaching and learning as well as in instructional design since the late 1970s. An important issue is whether conceptual change can provide a powerful framework for improving instructional practice in such a way that students’ levels of scientific literacy are significantly increased. In this article, the first section provides an overview on the development of conceptual change perspectives. In sections two to six, we examine the
This paper begins with a consideration of some important themes dealt with in the paper by Treagust and Duit. These include the relationship between research on conceptual change and educational practice, the significance of emotion and identity in the process of conceptual change, and role of cognitive conflict in motivating change. I then argue that the authors implicitly assert the importance of spoken dialogue as a motor for conceptual change, but do not give it the proper, explicit recognition that it deserves. I first use their own data of transcribed talk to make this point, and then go

In evaluating the success of teacher development programs, valid and scalable measures of teaching practice are needed. We have developed and validated the Science Lesson Plan Analysis Instrument (SLPAI) for quantitative evaluation of teacher-generated multiday lesson plans. This paper presents the SLPAI as a complement to surveys and classroom observation, and demonstrates its use in 2 pilot studies. The SLPAI was used formatively to measure the teaching practices of incoming program cohorts and tailor program instruction. It was also used to track changes in teaching practice and pedagogical

In the science education research literature, it often appears to be assumed that students "possess" more or less stable "images of science" that directly correspond to their experiences with scientific practice in science curricula. From cultural-historical and sociocultural perspectives, this assumption is problematic because scientific practices are collective human activities and are therefore neither identical with students' experiences nor with the accounts of these experiences that students make available to researchers. "Students' images of science" are therefore translated from

What effects do different setups of museum exhibits have on visitors' conversations and interactions? The study reported here is an investigation of the role that labels and associated materials play in visitors' conversations and interactions at a heat camera exhibit. After we introduced a label to help visitors explore the insulating properties of clothing, we found a dramatic shift in the kinds of activities and participation structures of visitors. Not only were visitors, as expected, discussing why clothing was warm, but they were doing so in a fashion more consistent with formal

This study examined whether parental involvement in children's science schoolwork (i.e., discussions about science, homework helping and encouragement of science interest) varies for boys and girls, and how these behaviors relate to children's science achievement beliefs (i.e., ability perceptions and task-value) at the end of a school year. We analyzed these links both for fathers and mothers and examined whether child gender moderates how parental behaviors relate to children's beliefs over time. Data were gathered over a span of a school year from 114 middle-school students (50% girls, 81%
Making assumptions is an important step in solving many real-world problems. This study investigated whether participants who could solve well-defined physics problems could also solve a real-world physics problem that involved the need to make assumptions. The participants, who all had at least a BA in physics, were videotaped “thinking aloud” while solving three well-defined and one real-world problem and then interviewed about the problem-solving process. All the problems dealt with the same scientific content. The recordings were analyzed to identify similarities and differences in the
At the 1939–1940 New York World's Fair, several thousand boys and girls, all members of a growing national network of high school science and engineering clubs, displayed their science fair projects and conducted live experiments to more than 10 million visitors. Housed in the building sponsored by the Westinghouse Electric and Manufacturing Company, their exhibits depicted a wide range of scientific phenomena. They also represented the conflicting values of science educators and industrialists about the societal worth of science education. In some instances, students' projects and laboratory
This paper reports on a study that employed metacognition and social cognition theoretical frameworks to explore and interpret students' views of their cognitive roles and the nature of the mechanisms that they considered influenced and mediated their learning within small group contexts. An instrumental interpretive case study methodology was used to capture students' descriptive accounts of their Year 11 Biology learning experiences, as conveyed through their recollections and reflections concerning their interactions and roles, perceptions of the learning task, and their learning strategies

The author discusses practices in running a university natural history museum. He notes that standards and customs in exhibits have changed, but suggests that there is value in keeping older exhibits as they are and highlighting the principles by which they were made. He notes that natural history museums have been focused on attracting children since the 1960s. He gives recommendations for keeping them child-centered but attracting adults as well. These include emphasizing the aesthetic side of the exhibits and being respectful of the work of prior generations, not attempting to compete with
