Describes the Alabama Science in Motion Program (ASIM) which provides hands-on science laboratories to high school students. Discusses the benefits of the program for host teachers and its impact on students and preservice teachers. (YDS)

This article discusses the rules science teachers need and how to implement these rules in the class. What should my science classroom rules be? Ideally, this question is asked prior to the teacher's entry to the classroom during their teacher training and revisited throughout their coursework preparation and student teaching. A science teacher…

The purpose of this study was to investigate the beliefs of six experienced high school science teachers about (1) what is successful science learning; (2) what are the purposes of laboratory in science teaching; and (3) how inquiry is implemented in the classroom. An interpretive multiple case study with an ethnographic orientation was used. The…

In an attempt to generate student enthusiasm on the subject of genetics, the author developed a Punnett square activity centered on the genetics of corn snakes to teach students about Mendelism and genetic diversity. As they began the activity, however, some unexpected twists occurred that allowed for investigation into corn snake anatomy and…

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…

The goals of this study were to increase communication between student and teachers in the Biotechnology 385 course, especially between the different modules of the course by designing a WebCT site for all four professors in the course, and to determine if the use of Flash animations integrated into the WebCT environment would increase student…

With each passing year, the public expects more of schools and teachers. Curricula become more complex, student populations become more diverse, responsibilities are added, and, except for resources, very little is taken away. Fundamentally, teachers are held responsible for everyone and everything that goes on in their classrooms, an awesome…

A hands-on approach to science is highly desirable because an inquiry approach to science greatly promotes learning. However when students and teachers manipulate glassware, chemical, and other materials, accidents will happen. Because of this, risk management and safety procedures become an important, integral part of the science curriculum. This…

This volume outlines the requirements and content of a second-year course in allied health occupations education that is intended to provide students with a practical understanding of the work done by medical laboratory technicians and technologists. Addressed in the individual units of the course are the following topics: the value of…

As networking systems have become more complex and expensive, hands-on experiments based on networking simulation have become essential for teaching the key computer networking topics to students. The simulation approach is the most cost effective and highly useful because it provides a virtual environment for an assortment of desirable features…

A simple experiment to study thermionic emission, the Richardson-Dushman equation and the energy distribution function of thermionic electrons emitted from a hot cathode using a triode vacuum tube is described. It is pointed out that such a distribution function is directly proportional to the first derivative of the Edison anode current with…

Solid-liquid and liquid-liquid mixing experiments have been developed to provide students with a practical experience on suspension and emulsification processes. The laboratory focuses on the characterization of the process efficiency, specifically the influence of the main operating parameters and the effect of the impeller type. (Contains 2…

An undergraduate laboratory was designed for undergraduate students to make long persistent light emitting diode (LED) indicators using phosphors. Blue LEDs, which emit at 465 nm, were characterized and used as an excitation source. Long persistent phosphors, SrAl[subscript 2]O[subscript 4]:Eu[superscript 2+],Dy[superscript 3+] (green) and…

This paper proposes a different experimental setup compared with the traditional ones, in order to determine the acceleration of gravity, which is carried out by using a fluid at a constant rotation. A computerized rotational system--by using a data acquisition system with specific software, a power amplifier and a rotary motion sensor--is…

A course linking chemistry and archaeology was designed to introduce scientific principles and applications to students with little or no science background. The course could provide students an opportunity to explore the role of the sciences in archaeology and to discover the relationship between materials and the culture that produce them.
