Science teachers usually view students' uncertainty as a barrier to overcome, a negative experience to be avoided, a deficiency in need of remedy. Building on the theory of deep learning in science as a generative and sensemaking process, the purpose of this design-based study is to identify tactics for teachers to manage their students' epistemic…

Research on learning progressions has led to advances in understanding student learning about big ideas in science, but teachers struggle to leverage the full potential of learning progressions for classroom instruction. Because learning progressions lay out how students' ideas change over a long period of time, learning progressions could help…

This article examines kindergarten children's (5-6 years old) engagement in scientific practices, with a focus on generating and using evidence to support claims, during a 5-month project about snails. The research questions are as follows: (1) what meanings do kindergarteners construct for what constitutes evidence? How are those meanings…

The shift in science education toward deeper, more integrated learning of domain content and scientific practices requires that teachers steer clear of strategies that promote the steady accumulation of more superficial knowledge and capabilities. Instead, teachers must invest in a continuous and gradual process of long-term growth in students'…

This article presents a study that examined an innovative short-term program (two sessions of 3 hr each) for the professional development of teachers. The program design is based on the technique of probing acceptance, which is aimed at investigating student learning processes. It relies on students' evaluation, paraphrasing, and adaptation of…

This study developed learning progression-based measures of science teachers' content knowledge (CK) and pedagogical content knowledge (PCK). The measures focus on an important topic in secondary science curriculum using scientific reasoning (i.e., tracing matter, tracing energy, and connecting scales) to explain plants gaining weight and…

Current research indicates that student engagement in scientific argumentation can foster a better understanding of the concepts and the processes of science. Yet opportunities for students to participate in authentic argumentation inside the science classroom are rare. There also is little known about science teachers' understandings of…

This study examined an interdisciplinary scientific research project to understand how graduate and undergraduate honors students learn to do science. It was found that the education of the students occurs as part of an apprenticeship. The apprenticeship takes place in research groups. In general, research groups are structured in two ways:…

In this study, we analyzed the quality of students' written scientific explanations found in notebooks and explored the link between the quality of the explanations and students' learning. We propose an approach to systematically analyzing and scoring the quality of students' explanations based on three components: claim, evidence to support it,…

Prior research in both education and cognitive science has identified analogy making as a powerful tool for explanation as well as a fundamental mechanism for facilitating an individual's construction of knowledge. While a considerable body of research exists focusing on the role analogy plays in learning science concepts, relatively little is…

Reports a study that investigated the relationship among (1) teacher's attitudes and implementation of inservice workshop developed learning cycle science materials, and (2) elementary school student's conservation reasoning and language used to describe properties of objects. Data were gathered from 100 students from grades K-5 and 16 teachers…

This study investigated whether Science Curriculum Improvement Study or more recent interpretations of the learning cycle could be used by teachers to engage students in social constructivist learning. Two researchers and six science teachers implemented instruction based on the reciprocal use of language and action. Changing beliefs and practices…

This study, conducted from a constructivist perspective, examined the belief system of a prospective elementary teacher (Barbara) about science teaching and learning as she developed professional knowledge within the context of reflective science teacher education. From an analysis of interviews, observation, and written documents, I constructed a…

This study examined the relationship that exists between high school teachers' (n=25) understanding of the Piagetian developmental model of intelligence; its inherent teaching procedure, the learning cycle, and classroom teaching practices. The teachers who exhibited a sound understanding of the model were more likely to effectively implement the…
