In the present study, I analyze ethnographic data from a year-long study of two Advanced Placement (AP) Biology classes that enrolled students with diverse racial, ethnic, and linguistic backgrounds. Specifically, I consider participation, positioning, and learning of newcomer Korean students in the focal classes. Building on the notion of figured…

Though addressing sources of uncertainty is an important part of doing science, it has largely been neglected in assessing students' scientific argumentation. In this study, we initially defined a scientific argumentation construct in four structural elements consisting of claim, justification, uncertainty qualifier, and uncertainty…

Students' declining science interest in middle school is often attributed to psychological factors like shifts of motivational values, decrease in self-efficacy, or doubts about the utility of schooling in general. This paper adds to accounts of the middle school science problem through an ethnographic, longitudinal case study of three…

We present the development of a construct map addressing the reason for the seasons, as a subset of a larger learning progression on celestial motion. Five classes of 8th grade students (N?=?38) participated in a 10-day curriculum on the seasons. We revised a hypothetical seasons construct map using a Rasch model analysis of students'…

This paper deals with the joint construction of knowledge by the teacher and the students in a physics classroom. It is focused on the status of epistemic certainty/uncertainty of knowledge. The same element of knowledge can be introduced as possible and thus uncertain and then evolve towards a status of epistemic certainty; the status of other…

There is widespread international concern about post-16 participation rates in science, with women's under-representation constituting a particular issue. This paper contributes to these debates through a novel, critical examination of the role of masculinity within boys' negotiations of science aspirations. Drawing on a UK longitudinal…

Engaging K-12 students in science-based inquiry is at the center of current science education reform efforts. Inquiry can best be taught through experiential, authentic science experiences, such as those provided by Student-Teacher-Scientist Partnerships (STSPs). However, very little is known about the impact of STSPs on teachers' and…

Helping students develop informed views about scientific inquiry (SI) has been and continues to be a goal of K-12 science education, as evidenced in various reform documents. Nevertheless, research focusing on understandings of SI has taken a perceptible backseat to that which focuses on the "doing" of inquiry. We contend that this is…

This study documents how an urban high school science teacher engaged her English Language Learners (ELLs) in the discourse-intensive science and engineering practices of (1) arguing from evidence and (2) obtaining, evaluating, and communicating information. The teacher taught an introductory integrated science course to classes with a large…

We compared designs of guidance to support students while interacting with dynamic visualizations of complex scientific phenomena in inquiry instruction. Three hundred thirty-two 7th-grade students were randomly assigned to either a reading or a generating condition and completed a web-based inquiry unit focusing on energy concepts in…

This paper explores how participating in a program spanning an informal science institution and multiple school sites engaged youth with science in a different way. In particular, teens in the program selected and researched science topics of personal interest, and then authored, revised, and published science news stories about those topics in an…

Learning progressions, or sequences of how ideas and practices develop within domains, are increasingly a focus of science education research. Recently, researchers have called for these progressions to be used as interpretive frameworks for teachers' instructional planning and assessment practices. In this study, we explore data from two…

Over the past two decades, science educators increasingly have become interested in the role of language in the learning of science and have drawn on the work of Bakhtin, among others, for understanding the dialogical nature of knowledge in a sociocultural framework. However, the nature of language and its relation to thinking have not…

In this study, we conducted in-depth interviews with 52 college graduates as they entered a Postbaccalaureate Research Education Program (PREP). Our goal was to investigate what it means for these aspiring scientists, most of whom are from groups underrepresented in the sciences, to feel ready to apply to a doctoral program in the biomedical…

This study explores the experiences of six urban middle school students in an authentic science inquiry program. Drawing on data including teaching journal entries, student work folders, and semi-structured focus group interviews of six participants, the findings explore six dimensions of authentic science inquiry, an approach to science inquiry…
