Resource | Appraising lexical bundles in mathematics classroom discourse: Obligation and choice
Working from a large corpus of transcripts from secondary mathematics classrooms, we identify patterns of speech that encode interpersonal positioning. We extend our analysis from a previous article (Herbel-Eisenmann, Wagner & Cortes, Educ Stud Math, 2010, in press), in which we introduced a concept from corpus linguistics—a “lexical bundle,” which has been defined as a group of three or more…

Resource | Analyzing Educational Policies as Designs for Supporting Learning
Submitted to The Journal of the Learning Sciences In this article, we describe and illustrate an analytical perspective in which educational policies are viewed as designs for supporting learning. This learning design perspective is useful when designing policies, when adapting policies to particular school and district settings during implementation, and when revising policies after…

Resource | A Symmetry POGIL Activity for Inorganic Chemistry
The goal of this project was to create an inquiry activity to teach symmetry elements and symmetry operations in an inorganic chemistry course. Many students experience difficulty when building and mentally manipulating three-dimensional mental models from two-dimensional images, causing difficulty when learning symmetry. Process-oriented, guided-inquiry learning (POGIL) was used to structure the…

Resource | A Design Pattern for Observational Investigation Assessment Tasks (Large Scale Assessment Technical Report 2)
The significance of inquiry skills is widely acknowledged in science practice across many areas.  Unlike experimentation, another form of inquiry skill, observational investigation has been much ignored in science education and thus science assessment.  Drawing on reserach development in assessment design, this report provides a design pattern to help assessment designers create tasks…

Resource | A Design Pattern for Experimental Investigation (Large-Scale Assessment Technical Report 8)
The significance of inquiry skills is widely acknowledged in science practice across many areas.  Carrying out experimental investigations is an indispensable element of scientific inquiry and, therefore, an important capability to assess. Drawing on research development in assessment design, this report provides a design pattern to help assessment designers create tasks assessing students'…

Resource | A cognitive apprenticeship for science literacy based on journalism
Abstract: The Science Literacy through Science Journalism (SciJourn) project aims to reframe the discussion of science literacy for citizenship, and explore how science journalism practices can be used to inform a cognitive apprenticeship that increases the science literacy of participants. This symposium features four paper presentations that report on the progress of the SciJourn project. We…

Resource | "Muddying the clear waters": Teacher's take-up of the linguistic idea of revoicing
This article examines a collaborative study group's discussions about “revoicing,” an idea from linguistics that has been identified as an important discourse strategy in the teaching of mathematics as well as other content areas. This group, made up of eight middle grades (grades 6–10) mathematics teacher-researchers (TRs), one university professor, and two graduate students in the United States…
