A theory of comprehension in verification tasks is developed from a general conception of language comprehension. Models are developed for a task involving transfer verbs "borrow" and "loan" and the possession verb "have." Models and theoretical framework are superior in some respects to constituent comparison and conversion models. (CHK)

Describes a set of biochemistry laboratory experiments in which tetrameric hemoglobin is separated into its subunits then formed again by recombination of the subunits. (MLH)

This article attempted to discover whether it would be both feasible and educationally desirable to extend the teaching of a foreign language to pupils who represented a wider range of age and ability than those to whom foreign languages had traditionally been taught. (Author/RK)

Explains the techniques of experimenting with the protozoan Colpoda cucullus to learn about its habitats, dispersal and adaptations. (LS)

Describes an experiment that gives useful insight into ideas of solvation and polarity of solvents. (GS)

Describes how to collect micrometeorites and suggests a number of related activities such as determining the number of meteors entering the atmosphere and determining the composition of the micrometeorites. (BR)

Using science experiments to motivate reluctant readers can be very successful with junior high school students. (JH)

Everyone who teaches physics knows very well that sometimes a simple device or experiment can help to make a concept clear. In this paper, inspired by "The Jumping Pencil" by Martin Gardner, I will discuss a simple demonstration device that can be used to start the study of air pressure.
