Practical, or laboratory, work is a common pedagogical strategy used in school science classrooms, yet its effectiveness for enhancing student learning is contested. Developing teachers' pedagogical knowledge about planning for practical work can improve its effectiveness by ensuring that tasks are well-conceived and effective for linking what…

Reform efforts in science and mathematics education highlight students' experiences and sensemaking repertoires as valuable resources for instruction. Yet, there is much to learn about how to cultivate teachers' capacity for eliciting, understanding, and responding to students' contributions. We argue that the first step of this cultivation is…

Teachers continuously engage in the relational work of sensemaking with students, but they generally do so isolated from colleagues, making individual decisions about their classrooms. Professional learning communities (PLCs), provide opportunities for collaborative professional reflection and development among peers centered on the analysis of…

Although microteaching is a common approach to engaging preservice teachers in reflection on teaching in on-campus courses, this reflection is usually carried out as a separate part. We examined how preservice middle school science teachers reflected amid planning a 20-min microteaching unit on sustainable development. Six groups of preservice…

This study examined teachers' expressions of the dynamic characteristics of open inquiry, which emphasize the scientific, continuous, and flexible thinking and affective aspects associated with the inquiry process. Metacognitive prompts supported teachers' reflections as they engaged in an open inquiry process. Using both qualitative and…

Although much research has examined the professional development (PD) of science teachers, questions remain about what aspects of PD contribute to teacher change. It is important to continue to examine the nuanced ways in which PD can support in-service science teachers as they seek to hone their craft. This study used silhouettes constructed from…

The use of video for in-service and pre-service teacher development has been gaining acceptance, and yet video remains a challenging and understudied tool. Many projects have used video to help pre-service and in-service teachers reflect on their own teaching processes, examine teacher-student interactions, and develop their professional vision.…

The current study, a uniquely challenging failed partnership, describes via an exploratory case study design the endeavors of a single middle school science teacher as he translated the reform messages of the Next Generation Science Standards into actual classroom practice. Data collected from both within and outside of the classroom revealed the…

Science, technology, engineering, and math (STEM) education has become an international focus of science education curricular reforms. However, few K-12 teachers have the background to authentically teach STEM in an integrated way. This is especially true of elementary teachers, who are often less confident or prepared to teach STEM disciplines…

This article is a qualitative study that explored bilingual/ESL science teachers' reflections about subject matter knowledge (SMK) and instructional practice in the elementary grades. Thirty-three teachers were part of a 5-year professional development program designed to enhance instructional quality and effectiveness to teach English learners.…

To increase the teacher efficacy of student teachers, they need positive classroom experiences: mastery experiences. These mastery experiences have to be created by the student teachers themselves. Therefore, student teachers need a tool to better understand problematic teaching experiences and help them create positive classroom experiences. Nine…

We investigated secondary science and mathematics teachers engaged in a two-and-a-half-year professional development effort focused on equity. We examined how teachers conducting research on their own instructional practices--a central learning strategy of the professional development project--informed and/or constrained their views related to…

In this nested mixed methods study I investigate factors influencing preservice elementary teachers' adaptation of science curriculum materials to better support students' engagement in science as inquiry. Analyses focus on two "reflective teaching assignments" completed by 46 preservice elementary teachers in an undergraduate elementary science…

In this study, pre-service teachers facilitated stations at a family science night as a context to learn to identify, assess, and use children's science ideas. Assessment is already difficult in K-12 classrooms. Assessing learning in informal learning environments adds the complication that participation is largely voluntary. As such, controlling…

This study used identity as a framework to understand how preservice science teachers develop the reform-minded ideas inherent in science-specific reforms. Six participants systematically reflected about their reform-based and field lessons taught during a methods course and field lessons taught during student teaching. Patterns in their…
