Described a program of bilingual learning that included different races of students and a goal directed toward hurdling built-in cultural advantages or handicaps. (Author/RK)

The probability of experiment-wise error is explored. Overall, the experiment-wise error rate is directly related to the test-wise error rate--the alpha level set by researchers to curtail the existence of a Type I error. A Type I error occurs when a true null hypothesis is rejected in a given study or experiment. The experiment-wise error rate is…

The background ideas and practical implementation that led to the use of a computer terminal in a physical chemistry laboratory are described. Outlines of two of the lab experiments being used in the program are included. (DT)

The role of spectral color slides in laboratory situations is discussed, then experiments for secondary school students concerning color and wave length, evidence of quantization, and the ionization energy of the hydrogen atom are outlined. Teaching guidelines for creating a set of spectrograms and photographic specifications are provided. (DT)

Describes a science activity, using a bacterium and a fungus, to illustrate the effects of competition and barriers on geographical distribution. (Author/PEB)

Describes an experimental "accident" that resulted in much student learning, seeks help in the identification of nematodes, and suggests biology teachers introduce similar accidents into their teaching to stimulate student interest. (PEB)

Described are projects and observations that can be conducted with the laboratory mouse to study mammalian growth and development. (RH)

We compared the performance of three heuristics with that of subjects on variants of a well-known combinatorial optimization task, the Traveling Salesperson Problem (TSP). The present task consisted of finding the shortest path through an array of points from one side of the array to the other. Like the standard TSP, the task is computationally…

A method of instruction is presented in which learners construct their own understanding by engaging in experiments directed to solving specified problems. The method is based on how successful inventors learn and create new inventions.

Here is a pen-portrait of a new-style tertiary college, North Devon College, Barnstaple. (Editor/RK)

Contains a list of articles on the author's varied experiences in the south seas, among primitive peoples and with the cultural factors that have given her new insights with which to solve educational problems. (RK)
