Bernoulli's principle is being misunderstood and consequently misused. This paper clarifies the issues involved, hypothesises as to how this unfortunate situation has arisen, provides sound explanations for many everyday phenomena involving moving air, and makes associated recommendations for teaching the effects of moving fluids.

Many of the basic concepts involved in the process of scientific inquiry can be represented by analogy to a simple game called Battleships. The same processes used in this child's game demonstrate what role hypothesis generation and testing play in the search for truth in nature. The analogy can also be extended to demonstrate how scientists…

Although members of the general public have often heard of the terms "genetic engineering" and, more recently, genomics, they typically have little to no knowledge about these topics, and in some cases are confused about basic concepts in these areas. There is currently a need for teaching models to explain concepts behind genomics.…

Hands-on science typically uses physical materials to give students first-hand experience in scientific methodologies, but the recent availability of virtual laboratories raises an important question about whether what students' hands are on matters to their learning. The overall findings of two articles that employed simple comparisons of…

This paper reports a study on elementary students' ideas regarding changes in mass associated with melting. An open-ended probe was designed and distributed to fifth-grade students (n = 230). In addition, 50 students were asked their reasons behind predictions on mass change. The written responses indicate that, despite conventional teaching,…

Throughout the world, and for many decades, science-rich cultural institutions, such as zoos, aquaria, museums, and others, have collaborated with schools to provide students, teachers and families with opportunities to expand their experiences and understanding of science. However, these collaborations have generally failed to institutionalize:…

The goal of the CAISE "Policy Study Inquiry Group" (PSIG) was to inventory and comment on policies (current or potential, organizational or governmental, explicit or implicit) which affect the capacity of informal science education to have an impact. This group represented a cross-section of organizations and entities that touch upon or play a…

Informal science education (ISE) experiences can provide powerful opportunities for people with disabilities to experience and learn about science. When designed to be inclusive, such experiences can lead people with disabilities to feel competent and empowered as science learners, generate excitement and enthusiasm for science, and be equitable…

This paper is an invited adaptation of the IEEE Education Society Distinguished Lecture Approaches to Interactive Video Anchors in Problem-Based Science Learning. Interactive video anchors have a cognitive theory base, and they help to enlarge the context of learning with information-rich real-world situations. Carefully selected movie clips and…

This study describes the characteristics of pre-service teachers' discourse on a WebCT Bulletin Board in their investigations of local streams in an integrated mathematics and science course. A qualitative analysis of data revealed that the pre-service teachers conducted collaborative discourse in framing their research questions, conducting…

This paper outlines the connection between qualitative research methods in education and teacher reflective practices as they relate to Valli's ("Reflective teacher education: cases and critiques." State University of New York Press, Albany, 1992; "Peabody J Educ" 72(1): 67-88, 1997) model of reflection. Using the authors' own experiences in…

This paper reports on an investigation of the effectiveness an intervention using several different methods for teaching solution chemistry. The teaching strategy comprised a four-step approach derived from a constructivist view of learning. A sample consisting of 44 students (18 boys and 26 girls) was selected purposively from two different Grade…

Critique is central to the development of scientific knowledge. From a cognitive perspective, critique can be used to enhance understanding. From a social perspective, critique serves to maintain the standards of a professional field. In science education, it is of tremendous value to diagnose and nurture students' critical knowledge. How students…

The purpose of this study was to assess differences between Nigerian junior and senior preservice teachers' science teaching efficacy beliefs. Data in this study were collected from a total number of 221 preservice teachers enrolled in junior and senior secondary science teacher education programs in Nigeria using Science Teaching Efficacy Belief…
