The "Framework for K-12 Science Education" (National Research Council, 2012) outlines eight practices to represent the diverse ways scientists construct and evaluate knowledge. Engaging students in these practices is a key instructional target in the science classroom. This target, however, creates particular challenges for online…

The national efforts underway to include engineering in K-12 science education present a variety of new challenges, including how to prepare teachers to teach a new discipline. In this paper, we focus on elementary teachers and how they enter into "responsive teaching," in which they closely attend and meaningfully respond to students'…

Through analysis of a classroom lesson led by a decorated teacher, we illustrate how instructional practices favor students seeking empirical patterns at the expense of using mechanistic reasoning. In the lesson, when students spontaneously come up with hypothetical mechanisms to explain why a light bulb in an electric circuit does or does not…

Studies of learning in school settings indicate that many students frame activities in science classes as the production of answers for the teacher or test, rather than as making new sense of the natural world. A case study of an episode from a class taught by the first author demonstrates what productive and unproductive student framing can look…

Despite myriad attempts over the years to design curricula with logical ordering and connections, concerns persist that students view science as a body of prescribed information to memorize. In this essay, we argue that attempts to build coherence into the curriculum reflect fundamental and enduring misconceptions about the nature of coherence…

When teachers or students assess the quality of ideas in science classes, they do so mostly based on "textbook correctness"; ideas are good to the extent they align with or lead to the content as presented in the textbook or curriculum. Such appeals to authority are at odds with the values and practices within the disciplines of science. There has…

This case study documents an example of inquiry learning and teaching during a summer institute for elementary and middle school teachers. A small group constructed an explanatory model for an intriguing optical phenomenon that they were observing. Research questions included: What physics thinking did the learners express? What aspects of…
