Abstract In this study, we examined students’ epistemological and positional framing during small group scientific modeling to explore their context‐dependent perceptions about knowledge, themselves, and others. We focused on two small groups of Korean eighth‐grade students who participated in six modeling activities about excretion. The two groups were purposefully selected because the students showed contrasting patterns of collaboration in modeling activities and sometimes showed significant

One of the major challenges in educational reform is supporting teachers and the profession in the continual improvement of instruction. Research-practice partnerships and particularly networked improvement communities are well-suited for such knowledge-building work. This article examines how a networked improvement community with eight school-based professional learning communities—comprised of secondary science teachers, science and emergent bilingual coaches, and researchers—launched into im

Calls to immerse students in the sensemaking practices of science recommend that students propose ideas and work together to construct explanations as well as drive the evaluation and decision-making around classroom knowledge-building. In other words, they should be participating with epistemic agency. Part of the teaching work of supporting student sensemaking, therefore, is to intentionally open up space for student contributions and negotiations during sensemaking. The type of space that is

Abstract Teaching to support students' sense‐making is challenging. It requires continuous, context‐dependent decision‐making about which student ideas to pursue, when, how, and why. This paper presents a single case study of an experienced teacher, Nadine, as an illustrative case in order to provide a rich description of this teacher's decisional episodes. Specifically, we characterize Nadine's pedagogical reasoning for decisions to make space for or close down student sense‐making while facili

Abstract Agency has been used as a lens to focus on how educators learn through pedagogical risk‐taking, advocacy for curricular reform, and resisting policies that are not focused on the needs of students. We explored the role of agency as 65 preservice science teachers created learning opportunities for themselves during their clinical placements. Specifically, we investigated whether the types of agentive episodes varied by the level of congruence novices perceived between the vision of scien

Abstract Few studies have examined how professional learning communities (PLCs) engage in collaborative inquiry over multiple years. This longitudinal study explored how a team of high school science teachers collaborated with researchers and district‐based coaches in a PLC over 4 years. We examined (1) how the PLC, which was situated in a culturally and linguistically diverse school that experienced high teacher and administrator turnover, shifted their collective inquiry and instruction from f

이 연구는 과학 정체성 개념을 사용하여 초등학교 4학년 학생들의 과학 관련 진로에 대한 포부를 탐색하는 것을 목적으로 한다. 연구를 위해 2013년 서울에 소재한 3개 초등학교의 4학년 학생들을 대상으로 한 과학 활동 경험에 대한 설문조사에서 과학에 대한 흥미는 높으나 관련 진로 포부가 낮다고 보고한 학생들(N=45)을 선별하였다. 이 가운데 연구 참여에 동의한 19명 학생들을 대상으로 과학 정체성(흥미, 능력, 타인에 의한 인정) 및 과학 관련 활동의 경험과 인식에 대해 심층 면담을 진행하였다. 면담에서 대부분의 학생들은 제한적이거나 상황적으로 유발되는 과학에 대한 흥미를 보였으며, 자신의 과학 능력과 과학 진로를 위해 필요한 능력의 차이, 또는 긍정적이지 않은 타인의 평가에 대한 인식을 가지고 있었다. 또한, 참여자들의 과학 정체성과 과학 관련 진로에 대한 낮은 포부는 과학 관련 활동에 대한 그들의 관심과 참여를 제한하였다. 참여자들은 대부분 상황적인 흥미를 유발시키는 일회적인

Abstract We explored how various contextual resources accumulated over multiple years operated together to facilitate a team of high school teachers' sustained and agentive learning after a 4‐year research–practice partnership (RPP) grant concluded. Specifically, we examined constellations of resources that promoted the co‐evolution of the teachers' collective inquiry in the professional learning community (PLC) and classroom instruction, focused on supporting students' scientific explanations.

Preservice teacher performance assessments, such as the edTPA, are one of the accountability policies from states and local authorities designed to ensure the quality of beginning teachers and standardize teacher education. We studied experiences of 65 preservice teachers regarding the effect of the edTPA on their learning in field-placement classrooms. These cases revealed that the edTPA created “protected teaching spaces” for participants to experiment with student-centered instructional pract

Phosphoinositide 3-kinases (PI3Ks) play key roles in synaptic plasticity and cognitive functions in the brain. We recently found that genetic deletion of PI3Kγ, the only known member of class IB PI3Ks, results in impaired N-methyl-D-aspartate receptor-dependent long-term depression (NMDAR-LTD) in the hippocampus. The activity of RalA, a small GTP-binding protein, increases following NMDAR-LTD inducing stimuli,and this increase in RalA activity is essential for inducing NMDAR-LTD. We found that R

The purpose of this study was to understand pre-service biology teachers’ scaffolding of students’ explanations in their inquiry teaching practices through their learning approach styles and orientations to teaching science. Four pre-service biology teachers were selected based on their science learning approach styles according to their answers on the R-SPQ-2F questionnaire developed by Biggs, Kember and Leung (2001). Two had deep approaches to learning and the other two had surface approaches

The clinical experience of preservice teachers can provide rich opportunities for them to learn about the work of teaching, but for many novices the opportunities are more limited because their host classroom does not reflect the type of instruction that they learn in their university coursework. Without these opportunities, preservice teachers (PSTs) may not get to apply, experiment with, and internalize the research-based teaching practices they are trained with. To address this challenge, thi
