This design-based research project reports on three multilevel networks that were focused on implementing the Next Generation Science Standards (NGSS). Given the recent attention to understanding infrastructure to craft coherence in NGSS implementation, this research investigated how these networks iteratively re-designed infrastructure as they…

Inquiry-Based Teaching Practice (IBTP) is an essential component of science education, and promoting its implementation is at the heart of various reform efforts. Even though science teachers regard IBTP as an essential pedagogical method, they rarely use it for various reasons. This study utilizes Bronfenbrenner's ecological framework to examine…

Around the world, there have been curricula reforms involving the incorporation of the inquiry-based teaching and learning strategy in secondary school science education in general and in practical work in particular. Research in inquiry-based practical work (IBPW) has focused, for example, on aspects of the strategy itself, on teacher…

This study examines the impact of a new master's degree program on the instructional practices of K-8 in-service teachers. This 2.5-year master's program was designed to deepen in-service teachers' knowledge in science and mathematics and promote greater use of reform-oriented instruction. Teachers' instructional practices were…

This article develops an argument that the type of intervention research most useful for improving science teaching and learning and leading to scalable interventions includes both research to develop and gather evidence of the efficacy of innovations and a different kind of research, "design-based implementation research" (DBIR). DBIR…

This article examines variations in patterns in the enactment of a large-scale kindergarten through Grade 12 science inquiry program. Student data reports in the GLOBE program provide a useful measure of implementation because key design elements in the program are student collection and reporting of local environmental data. We examined…

In this investigation we employed a case study approach with qualitative and quantitative data sources to examine and discover the characteristics of the processes used by a midwestern U.S. school system to adopt and implement a new K-6 science curriculum. Analysis of data yielded several results. Elementary teachers received what they requested,…

This article is about one school district's effort to reform its elementary science curriculum through a program of professional development called Science, Parents, Activities and Literature (Science PALs). The differential exposure of the district's K-6 teachers to Science PALs and differences in how well teachers implemented Science PALs-type…

Planned educational change occurs regularly throughout the world. With the enormous political change the 1994 elections brought to South Africa, a complete change in education policies was called for. The new Curriculum 2005 (C2005; Department of Education, RSA, [1997]) embraced new teaching and learning approaches such as outcomes-based education…
