Conveying an adequate conception of the nature of science to students is considered by many to be implicit in the broader context of what has come to be known as scientific literacy. It has also been demonstrated that possession of valid concepts of the nature of science do not necessarily result in better science teaching. This study examines the…

One aim of this study was to identify, in a group of unsuccessful college level problem solvers, the status and use of their declarative knowledge as revealed by students' attempts to solve novel problems in a pencil-and-paper setting. It was hypothesized that for some unsuccessful problem solvers, their problem representation could be improved by…

IN A STUDY OF THE EFFECTS ON LEARNING OF A FILM ON OCEANOGRAPHY, 477 GRADE 6 STUDENTS WERE RANDOMLY ASSIGNED TO A CONTROL GROUP NOT VIEWING THE FILM AND TO 12 TREATMENT GROUPS. INDEPENDENT VARIABLES WERE RESPONSE MODE, FEEDBACK (IN FORMS THAT PRESENTED AUDIOVISUAL OR AUDIO-ONLY FEEDBACK, PRESENCE OR ABSENCE OF CORRECT ANSWERS, AND SPACED OR…

A total of 102 children (17 from each of the kindergarten, first, and second grades and of two disparate socioeconomic backgrounds) were administered a series of tasks involving verbal recall. The purpose of this testing was to compare the verbal recall ability of children of different ages and socioeconomic status. The verbal material was read to…

The purpose of this study was to obtain quantitative nonevaluative data about verbal behavior used by instructor and students in the foreign language classroom. Two beginner and two intermediate German classes were tape-recorded for two weeks, then coded according to patterns. Frequencies of various verbal behavior patterns were analyzed. A…

This final report gives the findings of a government research project, the broad objective of which was to determine the existence of heightened covert oral behavior in the performance of tasks in which the response class had not yet been empirically studied and to ascertain the function of the covert oral response. Areas covered by this report…

To explore the efficacy of improving the dysarthria of cerebral palsy under conditions of aural stimulation, visual stimulation, and combined aural-visual stimulation, 22 subjects (aged 7.6 to 19.0 years) received intensive stimulation for word limitation for 22 consecutive school days. The 87 words of the Irwin Integrated Articulation Test were…

This paper discusses the findings from a study that investigated the information processing characteristics of 93 children (ages 8-16) who have been diagnosed as having either attention deficit hyperactivity disorder (ADHD) only, ADHD-Predominately Inattentive Type, and combined ADHD and learning disabilities (LD). Thirty-nine average students,…

This study investigated whether the visual forms of buttons influenced learning and satisfaction when early adolescent students were asked to perform tasks using computer-assisted instruction (CAI). Ninety subjects participated. Three visual forms were designed for buttons located in a CAI application. One contained pictures for commands, the…

Three experiments examined referential and associative linkages in memory as a function of stimulus and response material formats. Second grade, sixth grade, and university students were the subjects. In Experiment 1, subjects pointed to either the picture or printed name of a stimulus corresponding to the name or picture, respectively, pointed to…

A portable minicomputer collected data about elementary and secondary social studies teachers' oral questions and the subsequent verbal behaviors of the teachers and the students. Data indicated that literal types of questions were posed most often by teachers at the rate of l.5 per minute, and the duration of the students' answers was associated…

The purpose of this study was to examine the effects of verbal experience on children's creative expression and to develop more precise means for interpreting and evaluating children's art. Two questions were of interest: (1) Does the experimental approach described here enable children to resist forces tending to cause stereotyped artistic…

Evaluation problems evolving from certain objectives of intervention programs and from the characteristics of the target population are investigated. The intellectual process approach of experimental education with its emphasis on conative and motive objectives requires an evaluation technique capable of reflecting the desired behaviors more…

This report contrasts the results of a rigidly specified, pattern-oriented approach to learning Spanish with an approach that emphasizes the origination of sentences by the learner in direct response to stimuli. Pretesting and posttesting statistics are presented and conclusions are discussed. The experimental method, which required the student to…

Assesses children's ability to indicate verbally and nonverbally their awareness of two-octave pitch shifts in a familiar song. Compares abilities of English- and Spanish-speaking children by age and by native language. Discovers older children indicate changes more proficiently whereas Spanish-speaking children respond less often. Finds many…
