TWO HYPOTHESES RELATED TO HYPOTHESIS INTERFERENCE IN CONCEPT PERFORMANCE OF YOUNG CHILDREN WERE TESTED/ (1) STUDENTS MAKE MORE CLASSIFICATIONS WHEN STIMULUS OBJECTS ARE PRESENTED SEQUENTIALLY THAN WHEN STIMULUS OBJECTS ARE PRESENTED SIMULTANEOUSLY, AND (2) REDUCING THE NUMBER OF STIMULUS OBJECTS INCREASES CLASSIFICATION SPEED. MATCHED ON THE BASIS…

AN INVESTIGATION WAS CONDUCTED (1) TO DEVISE A NUMBER OF LABORATORY MEASURES OF INDIVIDUAL DIFFERENCES IN SUSCEPTIBILITY TO INTERFERENCE EFFECTS IN LEARNING AND (2) TO DETERMINE THEIR DIMENSIONALITY IN A VARIETY OF INTERFERENCE EFFECTS. SUBJECTS WERE 530 STUDENTS IN INTRODUCTORY COURSES IN EDUCATIONAL PSYCHOLOGY AT THE UNIVERSITY OF CALIFORNIA,…

A SERIES OF EXPERIMENTS WAS CONDUCTED TO TEST THE EFFECTIVENESS OF TELEVISED INSTRUCTION. THIS STUDY, THE THIRD IN A SERIES, EXPLORED THE ROLE IN FIXED-PACE TELEVISION INSTRUCTION OF SOME OF THE TECHNIQUES AND PRACTICES EMPLOYED IN TEACHING-MACHINE INSTRUCTION. THREE SEPARATE EXPERIMENTS WERE CONDUCTED--(1) A JUNIOR HIGH SCHOOL LESSON ON NEWTON'S…

The influence of situational expectations, conditioned by previous experience, on the interpretation of entire prose passages was investigated with 22 hearing and 18 hearing impaired adolescents. The ambiguous paragraph model was borrowed from D. Schallert and two separate paragraphs were constructed. Ten multiple choice questions were generated…

Reported are the results and conclusions of an arithmetic investigation made in the schools of Scotland in the spring and fall of 1966. The first problem in this investigation was to ascertain which, if either, of two unlike programs of instruction was more effective in developing skill in computation. The second was to determine the value of an…

This study deals with the following topics: (1) the extent to which three different learning environment instruments and their underlying conceptual framework are empirically related, and (2) the extent to which intensive observation of classrooms aids in the interpretation of instruments' characterizations of a class. In the first part of the…

A structured observation-interview procedure to gather data on programs of individualization was developed. The procedure assessed the degree to which a particular program is individualized. Individualized instruction was defined as a method in which instructional practices are adapted to the requirements of each learner. The report describes the…

The problem investigated was the relationship between cognitive category width and certain other cognitive and perceptual variables, with the intent of gaining additional insight into the effect which individual differences in cognitive conceptualization exert on certain other behaviors. Cognitive category width, defined as the score obtained on…

A classification of factors that go into the complex process of reading or learning to read is presented. These factors are listed in outline format under the following sections: (1) sensory input, (2) mediating activity, (3) response, (4) reward and/or motivation, (5) knowledge of results, (6) reward variations, (7) rate of reading, (8) practice…

Efforts to apply knowledge gained from the study of the psychology of learning to actual teaching have been largely marked by frustration--until recently--when programed learning and its special derivative, computer assisted instruction, made their appearance. In programed learning you know where the student is and what he is doing, and what he…

The subjects used in this study were 202 second grade pupils, representing the entire population from nine classrooms in four school buildings all located in a middle-class town. Treatment conditions were used which modeled reward conditions: (1) a neutral, no-overt-reward condition in which the tester quietly observed the subject working at the…

Experiments focused on (a) how a subject directs his attention and explores the problem environment created by the task to be learned, and (b) how the subject's learning process can be facilitated by CAI systems. In all experiments, the subject interacted with an automaton responsible for controlling the experimental environment. The automaton was…

The problem of designing computer programs that will approach human capabilities in pattern recognition is discussed. Human beings are much better at recognizing patterns that are highly structured than at recognizing patterns that are not. In contrast, a computer system's performance in pattern recognition is almost independent of the amount of…

This study was designed to investigate the effect of allowing students to generate their own problems and make their own decisions concerning their rate of progress through the instructional materials. An IBM 1500-1130 instructional system was used for the study. A program was developed to provide 72 different prototype arithmetic practice…

This investigation was made in a secondary school where the learning of algebra was studied during three years (Grades 7-9). There were 119 pupils divided into two experimental groups each of which had a different course in algebra. The content of these courses was measured by the number of written exercises. Many ability tests and attitude…
