Hypothesis behavior on three dimensional concept attainment problems was measured for 48 children (12 each at grades K, 2, 4, and 6). Every feedback trial was followed by a blank trial, a procedure that provided separate measures of Ss' ability to use hypotheses and test hypotheses. A S was considered to be "using" when his hypothesis inferred…

A study of elementary school students investigated the effects of immediate feedback during a spelling pretest compared to the usual delayed feedback after dictation of an entire word list. Results indicated a small degree of difference between methods. (Author/DF)

THIS RESEARCH EFFORT WAS DESIGNED TO INVESTIGATE THE EFFECTS OF (1) TWO DEGREES OF IMMEDIACY OF KNOWLEDGE OF RESULTS AND (2) THREE METHODS OF PRESENTATION ON THE RETENTION OF KNOWLEDGE TRANSMITTED BY A FILMSTRIP. A FILMSTRIP WAS PRESENTED FRAME-BY-FRAME, IN SEQUENCE, AND IN TOTAL WITH TEST ITEMS ON THE FILMSTRIP ADMINISTERED ACCORDINGLY. PUBLIC…

Four to five-year-old children were asked questions on length involving single or double comparatives in a transitive inference task. The number of comparatives varied within or across pairs. The pairs of sticks were color-coded. Initial pair-wise discrimination training on four adjacent pairs from a five stick array with only verbal feedback was…

Focusing on the application of new technologies to the creation of rich environments for writing, this project entailed the assembling of a low-cost microcomputer system that included a microcomputer, speech synthesis, voice recognition, and videodisk player. A variety of alternative input devices were explored, and software that permitted the…

In recent research, sequences of hypotheses observed during problem-solving have been categorized according to six hypothesis sampling systems that vary in efficiency. Three systems were characterized as strategies (focus, dimension check, hypothesis check) because they always lead eventually to solution. The remainder were called stereotypes…

The role of reinforcement has long been an issue in learning theory. The effects of reinforcement in learning were investigated under circumstances which made the information necessary for correct performance equally available to reinforced and nonreinforced subjects. Fourth graders (N=36) were given a pre-test of 20 items from the Peabody Picture…

Reports results of a study investigating effects of social interaction on utilization of categorical concepts by upper and lower class children. Describes an experimental guessing game with individual subjects and pairs of subjects. Concludes that the experimental setup was beneficial for all subjects regardless of social background or kind of…
