A study is reported in which 7 children (2 girls and 5 boys, 11 to 12 years of age) with a year of LOGO Programming experience were asked to think aloud about how a LOGO procedure would work, and then to predict by hand-simulation of the programs, what the graphics turtle "pen" would draw when the program was executed. While all children…

Considers possibility of developing a computer tutor around an explicit concept-learning theory derived from machine learning techniques. Some problems with using the focusing (and similar) algorithms in this role are discussed and possible solutions are developed. Design for a guided discovery learning system for tutoring concepts is proposed.…

A conceptual model was developed and assessed to examine the relationship between critical thinking and political participation. Although the empirical and theoretical bases for the model are not fully discussed, findings based on path analysis are presented. Based on data from 118 graduate and undergraduate students, the model affirms the…

Previous research has shown a relationship between formal reasoning ability and science process skill attainment. It has been hypothesized that an increased emphasis on teaching process skills might enhance the formal thinking abilities of students. A variety of strategies have been proposed to better accomplish this task, most notable, the…

Educational research has thus far failed to greatly improve education because it is based on a model of reality that emphasizes unilateral control in both research and practice. Efforts to gain unilateral control presume that researchers or practitioners know what is significant from the outset, that they are essentially outside the situation they…
