Students must understand the fundamental process of convection before they can grasp a wide variety of Earth processes, many of which may seem abstract because of the scales on which they operate. Presentation of a very visual, concrete model prior to instruction on these topics may facilitate students' understanding of processes that are largely…

Changes are occurring within Brazilian institutes of higher education; currently several universities are reviewing their course offerings and teaching approaches to determine if they meet the needs of today's undergraduate students. When changes are made to the curriculum of experimental courses, there should be an understood guarantee that all…

There is a childhood saying about a confused dog who thinks he sees a possum in a tree. The problem is that the possum is actually in a different tree so the dog barks up the wrong tree. American education is constantly playing both dog and possum. Sometimes they are the prey, and sometimes they are just confused about what and where the prey is.…

The National Inquiry Standard for Science Education Preparation requires science teachers to introduce students to scientific inquiry to solve problems by various methods, including active learning in a collaborative environment. In order for science teachers to comply with this inquiry standard, activities must be designed for students to…

This investigation explores how underrepresented urban students made sense of their first experience with high school science. The study sought to identify how students' assimilation into the science classroom reflected their interpretation of science itself in relation to their academic identities. The primary objectives were to examine students'…

For three biology professors, visualizing molecular processes is central to thinking in their discipline. This chapter reports their attempts at getting students to make this same cognitive move and the results of their assessments. (Contains 2 figures.)

The STArt! teaching Science Through Art program was developed to help both students and teachers address the new California Science Content standards. An initial presentation of program introduces molecular visualization using narrative discussions, handheld models, visualization software and art workshops and it also emphasize low-cost materials,…

Today's high school students and biology teachers alike face challenges arising from constantly-changing environments. From global warming to species reduction to energy policy, the issues the students will face will have immediate and long-lasting implications. At the same time, biology teachers are charged with achieving legislated standards,…

Incorporating inquiry-based learning in the college-level introductory biology laboratory is challenging because the labs serve the dual purpose of providing a hands-on opportunity to explore content while also emphasizing the development of scientific process skills. Time limitations and variations in student preparedness for college further…

To date, little of the ecological research on biological diversity and ecosystem functioning has been carried out in agricultural systems, despite the fact that agriculture is a major contributor to loss of native habitats and species. However, agricultural research has demonstrated that polycultures of multiple crop species can have higher total…

In these days of increasing concern for the state of the environment and declining biodiversity, it is important that students and teachers come to appreciate the value of life in all its forms. Natural history provides students with an opportunity to understand better how life on the planet interacts, as well as the place and responsibility of…

This paper develops a conceptual basis for a model on the teaching of socio-scientific controversial issues for secondary or high school students. I argue that the teaching of controversial issues needs a stronger theoretical base. Drawing on a liberal democratic conception of possible sources of conflict, three strands are developed that provide…

The problems many Indian children experience in schools-- low academic achievement, absenteeism, high drop-out rates-- cannot be solved by any one individual. Instead, it requires action by the entire school system and, especially, greater leadership by Indians themselves. Tribes must become partners in the process of school reform and become…

The aim of this study is to assess prospective teachers' views of some aspects of the nature of science (NOS) and the effects of a "Science, Technology and Society" (STS) course embedded with scientific investigation (SI) on these views. A questionnaire consisting of 13 items was given to 212 prospective teachers enrolled in a STS course…

The gradual, ongoing transformation of a large general education astronomy class is presented. Emphasis is on student reaction to and academic impact of changes in the teaching/learning environment introduced over a five-year period. In-class, cooperative, and small group exercises are discussed, along with web-based materials and Just-in-Time…
