In this study, we explored some of the factors related to the acceptance of evolution theory among Greek university students training to be teachers in early childhood education, using conceptual ecology for biological evolution as a theoretical framework. We examined the acceptance of evolution theory and we also looked into the relationship…

Our inquiry uses accounts from the history of science to develop teacher-candidate (student teacher) understanding of the nature of science (NOS) in a science teacher education methods course. This understanding of the NOS is then used as a foundation for developing teacher candidate appreciation of the attributes of authentic science lessons.…

As the breadth and depth of economic reforms increase in China, growing attention is being paid to equalities in opportunities to learn science by students of various backgrounds. In early 2009, the Chinese Ministry of Education and Ministry of Science and Technology jointly sponsored a national survey of urban eighth-grade students' science…

While Shulman argues that an important component of pedagogical content knowledge (PCK) is teachers' understanding of the alternative conceptions commonly held by students, relatively little is known about what students believe about many topics in the school curriculum. This paper focuses on a content area typically featured in Geography…

Providing model-based accounts (explanations and predictions) of water and substances in water moving through environmental systems is an important practice for environmental science literacy and necessary for citizens confronting global and local water quantity and quality issues. In this article we present a learning progression for water in…

Using a case study method, the experiences of a group of high school science teachers participating in a unique professional development method involving an argue-to-learn intervention were examined. The participants (N = 42) represented 25 different high schools from a large urban school district in the southwestern United States. Data sources…

Students are making choices in middle school that will impact their desire and ability to pursue STEM careers. Providing middle school students with accurate information about STEM (Science, Technology, Engineering, Mathematics) careers enables them to make more knowledgeable choices about courses of study and career paths. Practical ways of…

Interactive lecture demonstrations (ILDs) are a powerful tool designed to help instructors bring state-of-the-art teaching pedagogies into the college-level introductory physics classroom. ILDs have been shown to improve students' conceptual understanding, and many examples have been created and published by Sokoloff and Thornton. We have used the…

This laboratory experiment was developed to provide a safe, economical, and effective way to instruct undergraduate organic chemistry students about the unimolecular nucleophilic substitution (S[subscript N]1) reaction. Students treat 2,5-dimethyl-2,5-hexanediol with excess concentrated hydrochloric acid to synthesize…

At the heart of the vision for the Diploma in Science is a multidisciplinary approach to learning by tackling scientific challenges and questions in applied work-related contexts. This, together with the innovative delivery model offered by a consortia approach, will bridge a significant gap in the provision of science and mathematics education.…

Although there has been considerable focus on the underrepresentation of minorities in science, technology, engineering, and mathematics (STEM) disciplines and the need for science instruction that fosters diversity, much of the associated effort has focused on the goal of diversity and tended to assume that science and science learning are…

This study investigates defining characteristics among the process standards of the Principles and Standards for School Mathematics and the 5 "Es" from the National Science Education Standards and the Inquiry and the National Science Education Standards. These characteristics are used to demonstrate similarities and differences between the…

An interdisciplinary and context-driven course focused on global water issues was developed and taught at the college level. Students designed a semester-long research project, collected and analyzed data, and ultimately presented their results and conclusions to the larger community. As a result of the course, students' science literacy improved…

The dissociation constant, K[subscript d], of the binding of riboflavin-binding protein (RP) with neutral red (NR) can be determined by titrating RP to a fixed concentration of NR. Upon adding RP to the NR solution, the maximum absorption peak of NR shifts to 545 nm from 450 nm for the free NR. The change of the absorption can be used to determine…

The speed of light is an essential topic in the teaching of physics at school and at university, either with respect to the type of experiment or of course with respect to its genuine inherent importance. In reality, the various available experiments are hardly ever performed in class for many reasons. Therefore, we offer this experiment as a…
