Changes in college biology instruction in recent years reflect the changes in college instruction in general: information-dense textbooks, high-technology laboratory experiments, complex computer simulations, and easy exchange of data and ideas. Educators can now ask questions unthinkable by their classical forebears, and students can participate…

Presented are 27 science activities for secondary school science instruction. Topic areas include microbiology, botany, biochemistry, genetics, safety, earthquakes, problem solving, electricity, heat, solutions, mechanics, quantum mechanics, flame tests, and molecular structure. (CW)

Presented is a teaching progression that enhances learning through low-cost, manipulative transparencies. Discussed is instruction about restriction enzymes, plasmids, cutting plasmids, plasmid maps, recording data, and mapping restriction sites. Mapping wheels for student use is included. (CW)

Described are four musical instruments constructed from polyvinyl chloride (PVC) pipe. The use of computerized synthesizers to play scales and chords is discussed. Suggestions for other illustrations of acoustics are included. (CW)

Describes using the common house plant, "Coleus blumei," to illustrate gravitropic effects, phototrophic effects, and hormonal effects in plants. (PR)

Argues that a skills-based approach for the assessment of laboratory work is philosophically unsound, educationally worthless, and pedagogically dangerous. Proposes an alternative, holistic approach to assessment, based on a more valid model of scientific practice. (Contains 38 references.) (MDH)

The life history of the Chironomus tentans can be observed in easily established and maintained laboratory cultures. Projects for the classroom include observing hydration of an egg mass; embryonic development, hatching and larval feeding; larval activity; and mating activity. (MDH)

Argues that the transfer of plasmid from a bacterium to a plant cell has received little attention. Presents an experiment for studying this type of genetic transformation using the causative agent of crown gall, a malignant plant tumor. (DDR)

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…

Newborn screening has existed as a state-based public health service since the early 1960s. Every state and most territorial jurisdictions have comprehensive newborn screening programs in place, but in the United States a national newborn screening policy does not exist. This results in different administrative infrastructures, screening…

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…

This manual is intended as a resource for teachers who have special education students in their mainstream science classes, for curriculum adoption committees, and for publishers and consumers of science curriculum materials. Part 1 describes general characteristics of students with disabilities and provides general mainstreaming strategies and…

These supplemental units contain four laboratory exercises that can be used to enhance the labs in "Physics for the Technologies." The four units (one mechanical, two thermal, and one electrical) are designed to enhance labs in presenting specific concepts. Each unit can be used as an example of how the concepts behind the theory apply…

The study reported in the paper attempted to compare the science laboratory teaching practices and the learning environments of secondary schools in some developing and developed South Pacific countries. This study combined qualitative (observation, interview, and case study techniques) with quantitative methods. Analysis of data found similar…

Twenty-three self-contained single concept physics demonstration packages were designed and constructed at Lamar University (Texas). Each package was available for loan to pre-college science instructors in southeastern Texas in the spring and summer of 1987. During the spring, three high school physics teachers used the demonstrations and…
