Developing and Using a Scalable Assessment to Measure Preservice Elementary Teachers' Content Knowledge for Teaching About Matter
Resource
There is strong agreement in science teacher education of the importance of teachers' content knowledge for teaching (CKT), which includes their subject matter knowledge and their pedagogical content knowledge. However,…
Resource
Several recent studies have focused on helping students understand the limitations of empirical arguments (e.g., Stylianides, G. J. & Stylianides, A. J., 2009, Brown, 2014). One view is that students use empirical…
Validating the Use of Student-Level Instruments to Examine Preservice Teachers' Mathematical Problem Solving
Resource
Problem solving is a central focus of mathematics teaching and learning. If teachers are expected to support students' problem-solving development, then it reasons that teachers should also be able to solve problems…
Designing Educative Curriculum Materials for Teacher Educators: Supporting Preservice Elementary Teachers’ Content Knowledge for Teaching About Matter and Its Interactions
Resource
Research on teacher educators’ professional learning has gained increasing interest within science education. Curriculum materials have been suggested as a means of supporting teacher learning for several decades but have…
Eliminating counterexamples: A case study intervention for improving adolescents’ ability to critique direct arguments
Resource
Students’ difficulties with argumentation, proving, and the role of counterexamples in proving are well documented. Students in this study experienced an intervention for improving their argumentation and proving…
Examining Preservice Elementary Teachers’ Answer Changing Behavior on a Content Knowledge for Teaching Science Assessment
Resource
We use an online Content Knowledge for Teaching (CKT) assessment that measures PSTs’ CKT in one science area: matter and its interactions. In this study, we analyzed process data from administering the online CKT matter…
Elementary Science Teacher Educators Learning Together: Catalyzing Change With Educative Curriculum Materials and Vignette Writing
Resource
In this article, we describe a professional learning community (PLC) for science teacher educators that supported changes in pedagogy through educative curriculum materials and vignette writing.
In this…

The authors are developing a model for rural science teacher professional development, building teacher expertise and collaboration and creating high-quality science lessons: technology-mediated lesson study (TMLS…
In the Classrooms of Newly Hired Secondary Science Teachers: The Consequences of Teaching In-field or Out-of-field
Resource
Science teachers must sometimes teach outside of their expertise, and this type of teaching assignment is referred to as being out-of-field. Among newly hired teachers, this type of assignment may have a detrimental impact…
Compendium of Research Instruments for STEM Education, PART I: Teacher Practices, PCK, and Content Knowledge
Resource
The purpose of this compendium is to provide an overview on the current status of STEM instrumentation commonly used in the U.S and to provide resources for research and evaluation professionals. Part 1 of a two-part…
Pedagogical Chemistry Sensemaking: A Novel Conceptual Framework to Facilitate Pedagogical Sensemaking in Model-based Lesson Planning
Resource
Researchers have typically identified and characterized teachers’ knowledge bases (e.g., pedagogical content knowledge and subject matter knowledge) in an effort to improve enacted instructional strategies. As shown by the…
Examining Elementary Science Teachers' Responses to Assessments Tasks Designed to Measure Their Content Knowledge for Teaching About Matter and its Interactions
Resource
Despite the importance of developing elementary science teachers' content knowledge for teaching (CKT), there are limited assessments that have been designed to measure the full breadth of their CKT at scale. Our overall…
