Explains some of the ways in which dried yeast has been used in sixth-form work to illustrate some points and principles relevant to a high school biology course. (Author/GA)

Provides a reading list of articles and journals for high school biology on a wide range of topics. A few short articles and experiments on biology related topics are also given. (GA)

Describes the use of atomic spectra that are excited in inductively coupled plasmas for the simultaneous or sequential determination of the elements at all concentration levels. (HM)

This study was undertaken to develop an affective, small-group experience for helping children cope with death and to investigate the effectiveness of the experience in reducing children's anxieties about death. The generally positive results suggest that affective death education experiences such as this one should be made available to children.…

Three experiments assessed the effect of visual familiarity of words on "same-different" reaction times (RTs) in a simultaneous-matching task. All three studies showed visual familiarity to be responsible for differences in slope over sequence length between words and nonwords. (Editor/RK)

The relationship between the depth to which a word is initially processed and its eventual probability of being recognized was investigated with amnesiac (alcoholic Korsakoff) patients. (Editor)

After discussing the economic and social pressures which may impinge upon parental judgment in the experimental setting, the article reviews several divergent opinions on the ethics of child research. (Author)

A computer program which simulates an interstellar gas and dust cloud has been used to study Kirchhoff's laws of spectral analysis in introductory astronomy courses. The model parameters can be varied to stimulate various effects observed in actual clouds. Students are given exercises to use the program in a manner similar to a lab experiment.…

Describes the construction of a direct-reading inertial balance that works on the same principle as that used by astronauts in space when weightless. It is used to help demonstrate and measure inertial mass. (GA)

Describes the construction and use of a simple apparatus to measure the magnetization density and magnetic susceptibility of ferromagnetic, paramagnetic, and the diamagnetic solids and liquids. (Author/GA)

Principles, experimental procedures, results, and discussion of this method are included here. The method was used in undergraduate laboratory courses in Toulouse, France. (BB)

Two experiments investigated word-frequency effects with modified recall and recognition testing conditions. The procedural modifications included introducing partial copy cues and including irrelevant partial copy cues (distractor cues) in recall, and eliminating distractors from recognition tests. Words with high background frequency (HF) were…

This research tested Paivio's (1971) proposal that pictorial and verbal memory codes interact with space and time. This "interaction hypothesis" states that pictorial memory codes are specialized for spatial structures and verbal memory codes are specialized for temporal structures. Tests this hypothesis by exploring several variations…

Describes an experiment in which a presumptively behavioral anxiety-management technique known as "cue-controlled relaxation" (Russell, Miller & June, 1975) was compared with a "deactivated" version of Borkovec's (1972) Avoidance Response Placebo treatment and with no intervention as means of reducing self-reported test…

Describes three experiments which investigated the mechanism underlying memory for movement-extent cues in preselection. Experiment 1 showed that memory for movement extent was better for subjects who were allowed to preselect their own standard. Experiments 2 and 3 examined the role of active movement in preselected and nonpreselected movements.…
