This article describes beginner habits and misconceptions related to design practices. Once teachers are aware of these habits and misconceptions, they can more easily recognize them and work to remedy them through instruction. Presented herein are eight practice habits. Each item begins with the practice, describes a related design habit or…

This article describes ways to adapt U.S. science curriculum to the U.S. National Research Council (NRC) "Framework for K-12 Science Education" and "Next Generation of Science Standards" (NGSS), noting their focus on teaching the physical sciences. The overall goal of the Framework and NGSS is to help all learners develop the…

Stromatolites are the rocklike structures produced by "microbial mats"--communities of microorganisms only a few millimeters thick--as they trap, bind, or precipitate minerals. This article provides activities and assessment ideas to help teachers incorporate stromatolites in their classrooms. It relates the study of stromatolites to the…

Using the life sciences, this article first reviews essential features of the "NRC Framework for K-12 Science Education" that provided a foundation for the new standards. Second, the article describes the important features of life science standards for elementary, middle, and high school levels. Special attention is paid to the teaching…

The "Next Generation Science Standards" ("NGSS"), due to be released this spring, represents a revolutionary step toward establishing modern, national K-12 science education standards. Based on the recommendations of the National Research Council's "A Framework for K-12 Science Education: Practices, Crosscutting…

Using scientific debate focuses students on the real-life applications and implications of science and increases their reasoning skills, presentation skills, and science content knowledge. In this article, the author defines an "argument" as a position based on evidence and a "debate" as a formal setting in which two teams…

"A Framework for K-12 Science Education" identifies eight science and engineering practices for K-12 classrooms. These practices, along with core ideas and crosscutting concepts, define the nation's learning goals for science. An important advance from earlier standards (AAAS 1993, NRC 1996), these practices are clearly identified "not" as…

Science teachers can find lesson ideas almost anywhere. For example, during a recent visit to a local dollar store, the author stumbled upon a flower vase filled with water pearls, also known as water beads and jelly beans. She bought several of the bags (search the web to find numerous online sources), and soon began experimenting. Water pearls…

Creating inquiry activities is inherently difficult. Asking meaningful questions requires both background knowledge on the part of the students and complexity on the part of the phenomena. Yet numerous strategies can help teachers conduct inquiry activities. In this article, the authors share a taxonomy of teaching strategies used to create…

Despite significant pressure to reform science teaching and learning in K12 schools, and a concurrent call to reform undergraduate courses, higher education science content courses have remained relatively static. Higher education science faculty have few opportunities to explore research on how people learn, examine state or national science…

This paper reports on a study of teachers' actions when reading informational and narrative texts in the context of elementary science learning experiences. Focusing on the development of fundamental and derived senses of science literacy through the integrated science lessons, the research further explores the affordances of different genres…

The purpose of this study was to investigate elementary school pre-service teachers' understanding of photosynthesis and to examine if a refutational text can support understanding of photosynthesis better than a non-refutational text. A total of 91 elementary school pre-service teachers read either a refutational or a non-refutational text…

This longitudinal study examined the extent to which teachers' participation in a 3-year professional development program enhanced their self-efficacy and prompted changes in science instruction in the early elementary grades. The study used a mixed-methods design, and included 39 teachers who taught in kindergarten, first grade, or second…

This paper reports the findings of a study of the impact of the transformative professional development (TPD) model on student achievement on state-mandated assessments of science in elementary school. Two schools (one intervention and one control) participated in the case study where teachers from one school received the TPD intervention across a…

In 1609, Galileo Galilei turned his telescope to the night sky and began a series of observations of the cosmos. These observations, together with the work of Johannes Kepler and other scientists of the time, revolutionized our understanding of the universe and the process by which we do science. The United Nations General Assembly has proclaimed…
