Three experiments investigated the learning of simple associations in a color-word contingency task. Participants responded manually to the print colors of 3 words, with each word associated strongly to 1 of the 3 colors and weakly to the other 2 colors. Despite the words being irrelevant, response times to high-contingency stimuli and to…

A pencil lead successfully served as an electrode for the determination of ascorbic acid in commercial orange juice. Cyclic voltammetry was used as an electrochemical probe to measure the current produced from the oxidation of ascorbic acid with a variety of electrodes. The data demonstrate that the less expensive pencil lead electrode gives…

In delivering chemistry courses by distance, a key challenge is to offer the learner an authentic and meaningful laboratory experience that still provides the rigour required to continue on in science. To satisfy this need, two distance general chemistry laboratory courses appropriate for Bachelor of Science (B.Sc.) students, including chemistry…

Volume 1 of this study describes and costs two possible satellite networks which could be used in education in Canada. In order to determine whether these networks were plausible or useful, a letter and a description of the two hypothetical networks were sent, before the cost study was completed, to all Canadian Universities and provincial…

A series of educational experiments are being conducted in Canada on the Communications Technology Satellite. The description of these experiments reveals a diversity not previously encountered in educational applications of satellite systems. In evaluating these experiments, the authors adopted Stufflebeam's Context-Input-Process-Product model in…

Data are presented from a Canadian study to show that the cost of laboratory testing is escalating and represents a sizable proportion of hospital costs. Policy interventions will require thorough analysis and will require sophisticated control programs at various levels in the laboratory inquiry system. (Author/MLW)

The Junior High School Mathematics Consortium was a project in cooperative curriculum development involving 20 Alberta, Canada school systems. The project materials were developed and revised according to performance objectives developed by the Edmonton Public School Board, and the program unit booklets were developed cooperatively by ten school…
