Health-related career goals are popular among high school science students, yet few understand the application of chemistry and biology research to the field of medicine and its impact on society. In this five-day multidisciplinary summer camp, high school students learn about the real-world relevance of medicinal chemistry research and its…

Physical and life science disciplines emphasize how basic structural units influence function, yet it is challenging for students to understand structure-function relationships, particularly at molecular scales. Undergraduates in our biology capstone course struggled to connect mutations in a gene encoding a key protein in a cell development…

Advances in nanotechnology have drawn attention to nanotechnology education. The aim of this study is to determine awareness, exposure, and knowledge levels of science (physics, chemistry and biology) teachers about nanoscience and nanotechnology. Teachers (N=624) from secondary schools in Turkey comprised the working group. Descriptive methods…

The Innovative Technology in Science Inquiry (ITSI) project is a learning portal with hundreds of free, customizable science, math, and engineering activities funded by the National Science Foundation at the Concord Consortium, a nonprofit research and development organization dedicated to transforming education through technology. The project…

The aspiration of biology education is to give students tools to apply knowledge learned in the classroom to everyday life. Genetic modification is a real-world biological concept that relies on an in-depth understanding of the molecular behavior of DNA and proteins. This study investigated undergraduate biology students' conceptions of…

A well-ordered biological complex can be formed by the random motion of its components, i.e. self-assemble. This is a concept that incorporates issues that may contradict students' everyday experiences and intuitions. In previous studies, we have shown that a tangible model of virus self-assembly, used in a group exercise, helps students to grasp…

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…

A number of current reports are challenging educators of undergraduate biology students to increase the role, interactions and approaches of other disciplines. The goal stated in these reports is to produce a college graduate with the skills and competencies to solve pressing global problems such as producing ample food, fuels, and making health…

The large number of experimentally determined molecular structures has led to the development of a new semiotic system in the life sciences, with increasing use of accurate molecular representations. To determine how this change impacts students' learning, we incorporated image tests into our introductory cell biology course. Groups of students…

Presents various ideas on the origin of life including very early ideas, Oparin's view, and an alternative view related to carbonaceous chondrites. Outlines one currently tenable hypothesis in the formation of the solar system and explains the method involved in detecting polyatomic molecules in dark nebulae. (GS)

Describes a study involving 86 fifth-grade science students to enhance their understandings of basic biological chemistry. Contains a lesson that allows students to build models of atoms and molecules. (ZWH)

The quantity of information available on Co(III)-pentaammine complexes to the undergraduate students is based on their dissociatively activated substitution processes. The advanced undergraduate set of experiments is presented that fill an important gap in the understanding of the differences taking place in the substitution mechanisms operating…

Provides a theoretical model of the deoxyribonucleic acid (DNA) helix-to-coil transition in order to obtain magnitude information about the strength of the molecular bonds involved. (Author/CP)

Describes how to use the distinctive properties of osazone formation in conjunction with molecular model construction to demonstrate the relationship between the three-dimensional structures of simple sugars and the shapes of crystals they form. (BR)
