We present an inquiry-based, hands-on laboratory exercise on enzyme activity for an introductory college biology course for science majors. We measure student performance on a series of objective and subjective questions before and after completion of this exercise; we also measure performance of a similar cohort of students before and after…

Contemporary science standards stress the importance of highlighting inquiry in the science classroom as one way of learning key concepts. One critical question that needs to be addressed for a range of instructional practices is how opportunities to learn are conceptualized so that students can engage and learn the critical ideas and practices…

An environment appropriate for activity-oriented science is one that contains sufficient work space, equipment, and materials for students to practice and master the essential elements. This publication was developed to aid Texas school administrators, teachers, and architects to upgrade existing science facilities or plan new ones for…

Indicates that the most dangerous laboratory hazards are the least dramatic ones and that hazardous chemicals are often used in laboratories without proper precautions. Selected sources of information essential for secondary schools and recommendations for safe practices and chemical use statistics from a study of Ohio high schools are given. (DH)

A 1.5-MeV High Voltage Electron Microscope has been installed at the Lawrence Berkeley Laboratory which will help materials scientists and biologists study samples in more true-to-life situations. A 1-MeV Atomic Resolution Microscope will be installed at the same location in two years which will allow scientists to distinguish atoms. (DS)

Presents a series of behavioral objectives for a 60 hour science unit designed to train laboratory technicians in safety, basic laboratory skills, laboratory service and fittings, and first aid. (SL)

An important part of the science classroom involves teaching students how to safely use tools, techniques, and procedures. As emphasized in the National Science Education Standards, "safety is a fundamental concern in all experiential science" and teachers must "teach students how to engage safely in investigations inside and outside the…

This paper reports on an investigation of student engagement with e-learning, using practitioner reflection as a lens. Five e-learning practitioners each provided a case study from their teaching, which was the focus of practitioners' reflective accounts. Each of the practitioners had used e-learning as a way of promoting both learning and…

As a foundational course in medical education, gross anatomy serves to orient medical and veterinary students to the complex three-dimensional nature of the structures within the body. Understanding such spatial relationships is both fundamental and crucial for achievement in gross anatomy courses, and is essential for success as a practicing…

Students of exercise science are well positioned to facilitate a shift of the nation's attitude on health care from disease treatment to disease prevention. This report chronicles our efforts toward transforming the exercise physiology core course from a lecture-based, instructor-centered class to a student-centered environment in which…

Playing entertainment computer, video, and portable games, namely, digital games, is receiving more and more attention in academic research. Games are studied in different situations with numerous methods, but little is known about if and how the playing situation affects the user experience (UX) in games. In addition, it is hard to understand and…

A new, integrated laboratory curriculum was recently developed at the U.S. Naval Academy in response to the 1999 ACS Committee on Professional Training guidelines that required inclusion of biochemistry and a stronger emphasis on student research. To meet these ACS requirements and to introduce more student choice in the major, we embarked on a…

A National Research Council report has recommended practices for safe handling and disposal of hazardous chemicals in laboratories. They are a practical alternative to detailed regulations on individual chemicals. Topics discussed include physical hazards, chemical hazards, chronic hazards, laboratory ventalation, protective equipment,…

Summarizes a theoretical approach using nonbonding MO's and perturbation theory to correlate properties of saturated hydrocarbons. Discussion is limited to correctly predicted using this method. Suggests calculations can be carried out quickly in organic chemistry. (Author/SA)

Described is a demonstration science laboratory at the University of Florida. Discussed is laboratory design, including instructional space, lab stations, sink areas, safety areas, and a storage and distribution area. The impact of this type of design is cited. Diagrams and photographs are included. (CW)
