Equity-focused calls for elementary education reform recognize the importance of student and teacher translanguaging, yet nuances of how this process unfolds in early childhood science is an underexplored area. This study examines young plurilingual children's participation in science investigations, with a view toward understanding how open-ended…

This study was conducted in a large-scale environmental literacy project. In the project, we developed a Learning Progression Framework (LPF) for matter and energy in social-ecological systems; the LPF contains four achievement levels. Based on the LPF, we designed a Plant Unit to help Levels 2 and 3 students advance to Level 4 of the LPF. In the…

Teacher-led whole class discussions are essential when it comes to guiding students' construction of knowledge, and recent studies on teaching and learning emphasize the need for more student-centered teaching methods. In previous studies, the extent to which different types of communication take place in the classroom have been extensively…

Orchestrating inquiry-based science learning in the classroom is a complex undertaking. It requires fitting the culture of the classroom with the teacher's teaching and inquiry practices. To understand the interactions between these variables in relation to student learning, we conducted an investigation in two different classroom settings to…

Laughter is a fundamental human phenomenon. Yet there is little educational research on the potential functions of laughter on the enacted (lived) curriculum. In this study, we identify the functions of laughter in a beginning science teacher's classroom throughout her first year of teaching. Our study shows that laughter is more than a gratuitous…

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…

The findings reported on in this manuscript emerged from a design experiment conducted at a low-income urban middle school intended to support the teacher in incorporating pedagogical practices supportive of students' everyday knowledge and practices during a 6th grade unit on food and nutrition from the LiFE curriculum. In studying the impact of…

Modeling is a core practice in science and a central part of scientific literacy. We present theoretical and empirical motivation for a learning progression for scientific modeling that aims to make the practice accessible and meaningful for learners. We define scientific modeling as including the elements of the practice (constructing, using,…

Reports a study to analyze relationships between noverbal skills acquired by preservice science teachers in a methods course and their application during student teaching. Microteaching format was used in the experimental group to develop nonverbal cues and silence. Analysis indicated experimental preservice science teachers differed significantly…

The two-phase study was designed to (1) create a means whereby preservice teachers could lengthen the time they allow for a student to respond after posing a question; and (2) to study the relationship of want-time as an independent variable and dialogue measure, as a dependent variable. (RE)

Studies the effects of student-structured (SSLS) and teacher-structured (TSLS) teaching strategies. SSLS students consistently exhibited lower frequencies of teacher dependency behaviors than TSLS students. Need affiliation results varied with the grade level of students. (MA)

Explores how children's ideas in science affect elementary science instruction by investigating whether and how three primary teachers recognize and react to student ideas. Finds that the experienced teacher with the highest level of content knowledge had the largest repertoire for eliciting and addressing student ideas, and the intern teacher's…

In this study, we seek a better understanding of how individuals and their daily interactions shape and reshape social structures that constitute a classroom community. Moreover, we provide insight into how discourse and classroom interactions shape the nature of a learning community, as well as which aspects of the classroom culture may be…
