This study examined a cohort of middle school pre-service mathematics teachers' understanding of the rate of change as they engaged in a model development sequence. By adopting a design-based research perspective, a model development sequence on the concept of rate of change has been designed and implemented as part of a mathematical modeling…

Education for young adolescents must be challenging, relevant, integrative, and exploratory. Integrative teaching (e.g., interdisciplinary, multidisciplinary, cross-disciplinary, etc.) benefits middle-level learners as it potentially increases student engagement, motivation, and achievement. It provides learners with the opportunity to synthesize…

This report provides a description of a cognitive interview study investigating validity of assessments designed to measure "content knowledge for teaching" (CKT). The report is intended both to provide information on the validity of the CKT measures and to provide guidance to researchers interested in replicating the design. The study…

Within the educational research community, there have been a growing number of published research studies in teacher education that adopt a self-study approach. Researchers suggests that self-study in teacher education has the potential to animate the idea of teaching as reflection, model an inquiry-based approach to pedagogy, and generate rich…

Over 2 years a small group of middle school mathematics teachers' beliefs, attitudes, and practices were investigated in order to transform their practice to an inquiry-based, technology-rich model. Research has suggested that technology and pedagogical innovations should be introduced together, so that teachers learn mathematics in the way their…

This article reports findings from a 3-year study on preservice middle and secondary social studies teachers' common content knowledge of politics and current events. Surveys showed that both groups were generally uninformed about these issues, and on almost all measures, the middle-grades preservice teachers performed worse than those in the…

This study examined the extent to which seventh- and eighth-grade mathematics teachers are aware of National Council of Teachers of Mathematics (NCTM) standards documents, Curriculum and Evaluation Standards for School Mathematics and Principles and Standards for School Mathematics and agree with NCTM's vision of school mathematics as expressed in…

To add to the evidence base on effective strategies for teaching English language learner students, the 2006-2011 REL West at WestEd conducted a rigorous study, using an intent-to-treat model, of the impact on middle grades student achievement of offering teachers the opportunity to participate in a teacher professional development program. The…

The POWERSOURCE[c] intervention is a generalizable and powerful formative assessment-based strategy that can be integrated with any ongoing mathematics curriculum to improve teachers' knowledge and practice and, in turn, student learning. Our primary research objectives are based on our hypotheses that as a result of POWERSOURCE[c], teachers will…

Today's classrooms are more diverse than ever. In fact, research shows that there will be a steady increase in Hispanic, Asian Americans, and African American students in the coming years. Therefore, differentiated instruction may be the panacea that educators are searching for. This paper commences with an introduction and then segways into a…
