Across the United States, political leaders, educators, and business persons are issuing an urgent call for reform in STEM education (NGSS Lead States 2013). One important response to this call is Integrated STEM, which the National Governor's Association (2007, p. 7) says involves, "... an emphasis on design and problem solving in…

For some elementary science teachers, a unit on land and water brings nightmares of dirt and water all over the room. Several Earth science "kits" contain hands-on exercises that allow the students to "get messy" as they manipulate materials; however, these lessons may lack the necessary opportunities for students to ask unique…

Severe flooding was prevalent within the authors' region at the beginning of the school year. Many homes and fields were affected by the amount of rain that fell within a short period of time over multiple days. Their students were concerned about the impact this natural phenomena was having on their local community. Natural phenomena can provide…

The aim of the research was to identify how Slovenian primary and secondary school students of various age groups explain the particulate nature of the states of matter of water and air. The qualitative research included five 12, 14, and 16 year old students. A semi-structured interview including four computer-displayed tasks was used for the data…

This article describes an interdisciplinary project that created awareness of female scientists in a public Montessori classroom. Every spring, the author's sixth-grade students write an educational play in which the entire class participates. Following an underwhelming response to asking students who are their favorite female scientists, the…

The increase in ocean acidity since preindustrial times may have deleterious consequences for marine organisms, particularly those with calcareous structures. We present a laboratory experiment to investigate this impact with general, introductory, environmental, and nonmajors chemistry students. For simplicity and homogeneity, calcite was…

This study investigate the effectiveness of adding an "explicit general problem solving teaching strategy" (EGPS) to guided inquiry (GI) on pre-service elementary school teachers' ability to solve heat transfer problems. The pre-service elementary teachers in this study were enrolled in two sections of a chemistry course for pre-service…

During the century from the publication of the work by Einstein (1905 "Ann. Phys." 17 549) Brownian motion has become an important paradigm in many fields of modern science. An essential impulse for the development of Brownian motion theory was given by the work of Langevin (1908 "C. R. Acad. Sci.", Paris 146 530), in which he proposed an…

A number of well-known hydrostatics problems dealing with Archimedes' principle concern a loaded boat floating in a pool. Examples of this sort of problem include: 1. (a) If a stone is thrown overboard from a boat floating in a pool, does the water level in the pool rise, fall, or remain unchanged? (b) If a hole is made in the bottom of the boat…

This water conservation education program for high schools consists of both stand-alone activities and teacher support materials. Lessons are divided into six broad categories: (1) The Water Cycle; (2) Water and Society; (3) Keeping Water Pure; (4) Visualizing Volumes; (5) The Economics of Water Use; and (6) Domestic Water Conservation. The…

This study examined the impact of two epistemic commitments on the quality of college students' scientific reasoning in the domain of hydrostatics. These were the commitment to the consistency of theory with prior knowledge and commitment to the consistency of theory with evidence. Participants were 12 sophomore science majors enrolled in a large…

The aim of this study was to investigate effectiveness of PDEODE (Predict-Discuss-Explain-Observe-Discuss-Explain) teaching strategy in helping students make sense of everyday situations. For this, condensation concept was chosen among many science concepts since it is related to many everyday-life events. Forty-eight eleventh graders students…

Describes a teaching activity consisting of a problem-solving story about a company in a small town that is burying hazardous material which may create future problems for the community. The activity challenges students to address ethical issues relative to responsibility and accountability for protection of the water supply. (PR)

Presents an exciting way to acquaint students with current methods to clean up oil spills. Students also have the freedom to create new clean-up methods as they think through the problem and experiment to find effective solutions. (PR)
