Resource | Unpacking Core Teaching Practices in Elementary Mathematics to Support Teacher Learning and Assessment (Boerst, Moss, Blunk)
In this session, participants explore analytical language developed to “unpack” core practices in mathematics teaching (e.g., leading discussion) when guiding teacher learning and supporting assessment across contexts.

Resource | Tying Words to Images of Science Teaching (TWIST) (Roth)
Project Goals -Develop and field test a words-to-video images tool for analyzing selected features of science teaching. -Produce a Guide to Video Analysis of Science Teaching that includes a coding manual for the selected lesson features, a training guide for achieving inter-rater agreement, and a CD/DVD containing video segments for use as examples and for practice.

Resource | Towards an Empirically Grounded Theory of Action for Improving the Quality of Mathematics Teaching at Scale
Our purpose in this article is to propose a comprehensive, empirically grounded theory of action for improving the quality of mathematics teaching at scale. In doing so, we summarize current research findings that can inform efforts to improve the quality of mathematics instruction on a large scale, and identify questions that are yet to be addressed. We draw on an ongoing collaboration with…

Resource | The Use of Pictorial Supports as an Accommodation for Increasing Access to Test Items for Students with Limited Proficiency in the Language of Testing
This paper reports on an NSF-funded project that examines vignette illustrations (VIs) as a form of testing accommodation for English language learners (ELLs)—students who are developing English as a second language yet they are tested in English, in major assessment programs in the U.S. VIs are pictorial supports intended to make the contentof test items more accessible to ELLs without altering…

Resource | The Use of Illustrations in Large-Scale Science Assessment: A Comparative Study
In this paper, we report on a study that compares state, national, and international assessment programs as to the characteristics and functions of the illustrations used in their science test items. We used our conceptual framework for examining the characteristics of illustrations in science items (Solano-Flores & Wang, 2009, 2011) to code the illustrations of samples of items. We examined…

Resource | The Inquiry Project: Seeing Weight, Grasping Density (Doubler, Carraher, Asbell-Clarke)
⁃What does it look like to begin reasoning early about density before definitions and formulas? ⁃What sorts of classroom activities and teaching approaches might support this? Although it may be too early to formally introduce density in grade 4, it is not too early to begin reasoning about the concept. In the present examples, density is broached indirectly in activities of: (1) ordering…

Resource | The Evidence Games - Poster Session 2010
Since an August 2010 start date, the Evidence Game team has been engaged in an iterative design and development process for a game to provide middle school students and their teachers with practice in Toulmin’s (1984) model of argumentation as applied to science.  The poster session will present the overall conceptual model for a targeted game to provide practice in argumentation and efforts to…

Project Spotlight | New Measurement Paradigms
In June 2010, the New Measurement Paradigms (NMP) work group emerged as an active subset of a larger DR K-12 assessment community. In this spotlight, CADRE invites you to take a closer look at the report that came out of their work together and the people and projects involved. This is one of a series of spotlights that feature projects working in a particular area of STEM education research. If…

Resource | Synthesis and Characterization of Self-Assembled Liquid Crystals: p-Alokxybenzoic Acids
Thermotropic liquid crystal phases are ordered fluids found, for some molecules, at intermediate temperatures between the crystal and liquid states. Although technologically important, these materials typically receive little attention in the undergraduate curriculum. Here, we describe a laboratory activity for introductory organic chemistry students on the synthesis and characterization of the p…
