This paper introduces the biology laboratory as a learning project. Biology laboratories provide unique learning opportunities to students as traditional achievement outcome measures, and play an important role in the development of process skills, manual skills, and attitudes. However, there is insufficient data on undergraduate students majoring…

In the field of science, the meaning of insight can be understood by looking at theories which deal with universal laws that have fundamental significance for the totality of matter, independently of conditions of time and space. (JN)

Briefly describes functions of the Clearinghouse on Science and Human Rights, a project of the AAAS Committee on Scientific Freedom and Responsibility. (CS)

Reported is a study designed to determine conceptualizations of scientific concepts, laws and theories (linguistic structure of science) held by 80 Kwara State, Nigeria, secondary school science teachers relative to conceptualizations identified with seven philosophers of science. (Author/DS)

Describes how teachers can use wheels of tricycles, bicycles, and trains to stimulate children with mathematics, relative position, and engineering concepts. Techniques are offered for measuring circumference of a bicycle wheel, gear ratios, and pedal wheel circumferences. Comparative data are given for various sized wheels. (Author/SA)

Describes a method for students to evaluate and experience a repetition of important physics concepts during regular lecture sessions. The major goal was to train students to focus attention on course materials. (SK)

This column for high school teachers, written by high school teachers, discusses several interesting anecdotes related to the formulation of laws and the determination of constants. Science history is presented in a manner that can enliven classroom presentations and aid in understanding the principle itself. (Authur/SA)

Presents a classroom activity that tests students' parapsychological powers and can demonstrate a number of methods of science, including the processes of formulating a hypothesis and rigorously subjecting the hypothesis to testing. (DDR)

Describes a study providing evidence of how students' talk and writing about the nature of science differs depending on the particular scientific topic under discussion. Describes the relationship between theory and evidence, warrants for belief, and nature of observation. (Contains 25 references.) (Author/YDS)

Describes the development and use of a web site designed to engage middle school students in problem-based learning while addressing science education standards related to cell biology, technology, social aspects of science, and the nature and history of science. Students learn about naturally occurring opiates as they solve a mystery and conduct…

Introduces a computer solution of the oscillation of a mass suspended by a spring in a viscous liquid. Describes the equations of motion, spreadsheet solution, copying the formulas, plotting the results, and extending the applications. Presents spreadsheet and physics formulas for the step-by-step solution and spreadsheet solution. (YP)

Explains the use of a cropping systems project to teach agronomic principles and crop management techniques, and to enhance communication skills. Provides a sample progress report instructions sheet which was used for the project. (Author/RT)

Notes that energy is a difficult concept to learn and provides problems for many students. Stresses that if the science education community were to develop a standard nomenclature of energy-related terms, it would be possible to eliminate some of the difficulties without reducing depth of treatment. (Author/MVL)

Discusses the orbit, motion, and phases of the moon. Describes three activities on the moon: "How Soon Can You See a Crescent Moon?"; "When is the Moon Visible?"; and "Lunar Eclipses." (YP)

Investigates the remediation of misconceptions through application of Gagne's hierarchical learning theory. Uses stoichiometry, food levels, and conservation of mechanical energy as the target concepts. Reports that there was no treatment effect in analysis of covariance using pretest scores as a covariant. (YP)
