The aim of this research was to identify and analyse the concepts and ideas related to the nature of science, scientific concepts, and teaching and learn about science developed by a group of teachers during a training course for the teaching of sciences skills. The educational strategy was developed from a critical position on the expository…

In this mixed methods study, the researchers developed a video-based measure called a "Prediction Assessment" to determine preservice elementary teachers' abilities to predict students' scientific reasoning. The instrument is based on teachers' need to develop pedagogical content knowledge for teaching science. Developing a knowledge…

In this article, the authors argue for a design process in the development of educative curriculum materials that is theoretically and empirically driven. Using a design-based research approach, they describe their design process for incorporating educative features intended to promote teacher learning into existing, high-quality curriculum…

This study reports the secondary analysis of evaluation data from an innovative high school biology curriculum focused on infectious disease (ID) to examine the health literacy implications of teaching claims evaluation, data interpretation, and risk assessment skills in the context of 21st-Century health science. The curriculum was implemented…

This research focuses on inservice science teachers' conceptions of nature of science (NOS) before and after a two-week intensive summer professional development (PD). The PD combined traditional explicit NOS instruction, numerous interactive interventions that highlighted NOS aspects, along with documentary films that portrayed NOS in context of…

Understanding the nature of science (NOS)--what science is and how it works, the assumptions that underlie scientific knowledge, how scientists function as a social group, and how society impacts and reacts to science--is prominent in science education reform documents (Rutherford and Ahlgren 1990; AAAS 1993; McComas and Olson 1998; NRC 1996; AAAS…

In their research, scientists generate, test, and modify scientific models. These models can be shared with others and demonstrate a scientist's understanding of how the natural world works. Similarly, students can generate and modify models to gain a better understanding of the content, process, and nature of science (Kenyon, Schwarz, and Hug…

For science to be taught properly and effectively, labs must be an integral part of the science curriculum. The National Science Teachers Association (NSTA) recommends that all preK-16 teachers of science provide instruction with a priority on making observations and gathering evidence, much of which students experience in the lab or the field, to…

Making connections is an emerging education theme of the 21st century. Science teachers are encouraged to connect new learning with prior knowledge, learning with student interests and experience, and classroom activities with the history and nature of science. Strategies that facilitate these connections enrich and enhance instruction. In this…
