Celebrating Jhumki Basu’s contributions to science education as a scholar and an activist: voices from the field

This metalogue addresses the ways Sreyashi Jhumki Basu mediated our practices in science education and life. We focus on Basu’s uses of critical science agency, democratic science classrooms, and critical feminist ethnography to transform the possibilities for all participants in her research and educational practices. We also examine her use of cases and pedagogical strategies to support youth set practice goals based on conceptions of self and preferred learning trajectories. These strategies allow youth to develop power through the use of disciplinary knowledge and modes of inquiry to support their understanding of themselves as powerful, able to change their position in the world, and make the world more socially just. This (Key Contributors) article acknowledges a life cut short through disease, reflects our personal loss of a friend and colleague, and expresses determination to ensure that her contributions to science education are sustained and continued.

Does the Cognitive Interview Promote the Coherence of Narrative Accounts in Children With and Without an Intellectual Disability?

We examined whether the cognitive interview (CI) procedure enhanced the coherence of narrative accounts provided by children with and without intellectual disabilities (ID), matched on chronological age. Children watched a videotaped magic show; one day later, they were interviewed using the CI or a structured interview (SI). Children interviewed using the CI reported more correct details than those interviewed using the SI. Additionally, children interviewed using the CI reported more contextual background details, more logically ordered sequences, more temporal markers, and fewer inconsistencies in their stories than those interviewed using the SI. However, the CI did not increase the number of story grammar elements compared with the SI. Overall children interviewed with the CI told better stories than those interviewed with the SI. This finding provided further support for the effectiveness of the CI with vulnerable witnesses, particularly children with ID.     

Eye‐rollers,risk‐takers,and turn sharks: Target students in a professional science education program

In classrooms from kindergarten to graduate school, researchers have identified target students as students who monopolize material and human resources. Classroom structures that privilege the voice and actions of target students can cause divisive social dynamics that may generate cliques. This study focuses on the emergence of target students, the formation of cliques, and professors' efforts to mediate teacher learning in a Master of Science in Chemistry Education (MSCE) program by structuring the classroom environment to enhance nontarget students' agency. Specifically, we sought to answer the following question: What strategies could help college science professors enact more equitable teaching structures in their classrooms so that target students and cliques become less of an issue in classroom interactions? The implications for professional education programs in science and mathematics include the need for professors to consider the role and contribution of target students to the learning environment, the need to structure an equitable learning environment, and the need to foster critical reflection upon classroom interactions between students and instructors. © 2006 Wiley Periodicals, Inc.

Understanding conceptual change: connecting and questioning

We engage in a metalogue based on eight papers in this issue of Cultural Studies of Science Education that review the state of conceptual change research and its possible affect on the teaching and learning of science. Our discussion addresses three aspects of conceptual change research: theoretical, methodological, and practical, as we discuss conceptual change research in light of our experiences as science educators. Finally, we examine the implications of conceptual change research for the teachers and students with whom we work.

Adapting to Learner Attributes: experiments using an adaptive tutoring system

A composite learner model for adaptive tutoring systems has been developed, which combines a model of learner attributes with a simple overlay model of the learner's domain knowledge state. The model of learner characteristics enables several different forms of psychological and background data about the student to be taken into account, and provides a profile of the learner in terms of pedagogically useful attributes. An Adaptive Tutor Using Learner Attributes (ATULA) has been constructed, which uses the composite learner model. The system is able to select for the learner the optimal form of the learning material for the group of topics about to be presented. Experiments carried out with the adaptive tutoring system over 3 successive academic years with two disparate groups of students are described. User records collected during the experiments provide insight into the operation of the model, both at initialisation and during the student's interaction with the system. Previous users’ records also enable comparisons to be made with the result of previous experiments using a non‐adaptive system.     

SMEC (her/his)tories

This collection of historical accounts provides diverse perspectives on the structure and culture of the community of researchers who completed their studies under the mentorship of researchers at SMEC. These her/histories provide multiple perspectives on the goals and values that motivated educators to become SMEC scholars.     

Social norms and self-presentation: children's implicit and explicit intergroup attitudes

Two studies examined whether social norms and children's concern for self-presentation affect their intergroup attitudes. Study 1 examined racial intergroup attitudes and normative beliefs among children aged 6 to 16 years (n=155). Accountability (i.e., public self-focus) was experimentally manipulated, and intergroup attitudes were assessed using explicit and implicit measures. Study 2 (n = 134) replicated Study 1, focusing on national intergroup attitudes. Both studies showed that children below 10 years old were externally motivated to inhibit their in-group bias under high public self-focus. Older children were internally motivated to suppress their bias as they showed implicit but not explicit bias. Study 1, in contrast to Study 2, showed that children with low norm internalization suppressed their out-group prejudice under high public self-focus.     

OGRE: Three-Dimensional Program Visualization for Novice Programmers

As demonstrated in our earlier paper (Milne and Rowe, 2002), students learning object-oriented programming find topics related to the computer's handling of memory the most difficult to understand. Our results indicated that a visualization of a running object-oriented program, with particular emphasis on the display of how objects are related to each other in memory, would help students to learn these topics.Here we describe OGRE (Object-oriented GRaphical Environment) – a program visualization tool that has been developed to specifically address these memory related issues by providing three-dimensional, interactive visualizations that aid higher-level understanding of a program's execution in memory. OGRE has been evaluated with positive results that show significant improvements in students' understanding of C++'s memory-related topics.     

Coteaching and Disturbances: Building a Better System for Learning to Teach Science

Science education research has examined the benefits of coteaching for learning to teach in elementary and secondary school contexts where coteachers bring variable levels of experience to the work of coteaching. Coteaching as a pedagogical strategy is being implemented at the university level but with limited research. Drawing from the field of activity theory and our emic experience as coteachers, we examine the enactment of coteaching in university science education courses. One of the tools central to our examination of coteaching included the analysis of disturbances in the work and object of preparing science teachers. This analysis highlighted the role, during discursive interactions, of problem posing and problem solving for addressing observed disturbances. The presence of an extra instructor provided increased opportunities in the system for recognizing and valuing disturbances as indicators of underlying contradictions or tensions in elements of the activity system of the learning and teaching of science teachers. Our analysis suggests that coteaching offers expanded opportunities for the evolution of the activity system of preparing science teachers.
