Logarithms are notorious for being a difficult concept to understand and teach. Research suggests that learners can be supported in understanding logarithms by making connections between mathematics and science concepts such as pH. This study investigated how an integrated chemistry and mathematics lesson impacted 29 teachers' understanding of the…

This study investigates whether elementary science teachers participating in a four-week professional development workshop develop new understandings about classroom discourse and whether they are able to implement strategies toward teaching science as student-to-student discourse. Perspectives and the extent of teacher use of discourse strategies…

Effective professional development that influences teachers' classroom practices starts with what teachers know, understand, and do in their classroom. The Next Generation Science Standards (NGSS) challenge teachers to make changes to their classroom; to help teachers make these changes, it is necessary to know what they are doing in their…

This paper examines professional development workshops focused on Connected Math, a particular curriculum utilized or being considered by the middle-school mathematics teachers involved in the study. The hope was that as teachers better understood the curriculum used in their classrooms, i.e., Connected Math, they would simultaneously deepen their…

Two related case studies of secondary mathematics teachers examine the roles and conditions helpful in initiating, directing, and/or supporting teachers' own professional development. Using multiple data sources from school-based and professional settings, we applied analytic induction to identify patterns of similarities and differences in…

The aim of this research is to describe the development of the Science Teachers' Pedagogical Discontentment Scale, an instrument that measures the discontentment that arises in teachers as they recognize a mismatch between their own pedagogical beliefs and goals and their actual classroom practices. From a conceptual change perspective, we explore…

This paper is a report of the impact of an externally funded, multiyear systemic reform project on students' science achievement on a modified version of the Third International Mathematics and Science Study (TIMSS) test in 33 small, rural school districts in two Midwest states. The systemic reform effort utilized a cascading leadership strategy…

The study examined relationships among key domains of science instruction with English language learning (ELL) students based on teachers' perceptions of their classroom practices (i.e., what they think they do) and actual classroom practices (i.e., what they are observed doing). The four domains under investigation included: (1) teachers'…

Science is a dynamic discipline, representative of the nature of science. Yet, young science students continue to think everything is already discovered. In this study, we examine why students are not actively doing science. From professional development to student engagement, how are classrooms and students changing as we increase teachers'…

The Information Technology in Science (ITS) Center for Teaching and Learning was a National Science Foundation funded program to provide high-quality professional development for 7-12th grade science teachers. The subgroup on which this paper focuses was immersed in an innovative approach to understanding chemistry of the environment. The group…

Due to the recent advances in video technology, an increased incorporation of videos and multimedia materials is used in teacher education, commonly for demonstration of good practices or as a reflection tool for teacher professional development. However, video cases can never fully replicate the complexity of working in a real classroom. Watching…

The squeeze on instructional time and other factors increasingly leads educators to consider mathematics and science integration in an effort to be more efficient and effective. Unfortunately, the need for common understandings for what it means to integrate these disciplines, as well as the need for improving disciplinary knowledge, appears to…

This article focuses on the impact a collaborative project between university graduate fellows and K-12 classroom teachers had on improved pedagogy in the classroom and in the future at the university. Nine teams participated in a yearlong professional development project to improve pedagogy and communication skills of the participants. This study…

Describes the domains of knowledge needed by teachers to build and deliver excellent mathematics programs and the interaction of those knowledge domains. Discusses the impact of curriculum change, the nature of teacher education programs, problem-centered/inquiry-based teaching, demands on teachers, and the role of professional development.…

Focuses on the instructional development of a professor of environmental engineering in collaboration with science education and higher education faculty members. Discusses the results of professional development in the areas of questioning strategies, thinking time for students, facilitating students' participation, and implementing…
