The objectives of this study were (1) to observe and describe the social quality and the cognitive type of spontaneous play exhibited in a group of 20 children in a child care setting during two age periods, toddler (14-30 months) and preschool (30-48 months), and (2) to chart the developmental trends using a model of play complexity derived from…

The purpose of this pilot project was to determine whether involvement, as described by verbal and nonverbal indicators, increased as children worked at language arts learning centers characterized by increasing possibilities for involvement. Twelve first graders, randomly selected from an open space school, were each observed at three learning…

One aim of criterion-referenced testing is to classify an examinee without reference to a norm group; therefore, any statements about the dependability of such classification ought to be group-independent also. A population-independent index is proposed in terms of the probability of incorrect classification near the cutoff true score. The…

The utility and precision of scaling 200 relatively short reading passages were analyzed using a Rasch-based measurement technique as compared to readability estimates using the Spache or Dale-Chall formulas. In addition, a regression model was specified for predicting the grade level of a text a student could literally comprehend based on…

Three questions are addressed in this study: (1) what is the effect of additional, unexplained content on achievement and perception? (2) is the effect altered by time? and, (3) what is the relation between student achievement and student perception? It was determined that the effect on achievement was not significant but the effect on perception…

In simultaneous learning two verbal lists are interlaced for study, with each tested separately. In the present experiments simultaneous learning was used as a means of determining the conditions under which study time or learning resources might be reallocated between lists. One of the lists was called the standard list and remained constant…

It was hypothesized that using asterisks as attention focusing devices would cause students to read all asteriked test items more carefully and would improve test scores of undergraduate education students. Sixty-three undergraduates majoring in elementary or special education were administered a 36-item objective test. Asterisks were used to…

The accuracy with which testees perceived the difficulty of ability-test items was investigated by administering two 41-item conventional tests on verbal ability. High- and low-ability groups responded to test items by choosing the correct alternative and then rating each item's difficulty relative to their levels of ability. Least-squares…

Two experiments were conducted using nine- through twelve-year-old readers to determine how they differed from adults in their ability to identify meaningful units in a written passage, how they were affected by sentences of increasing difficulty, and whether they would be aided by either shorter sentences or meaningful segmentation of sentences.…

The relationship between television program variables and children's attention was examined using sample shows from two nationally distributed educational programs. Shows were coded at 30-second intervals on four measures of program complexity and two measures of the relationship between verbal and visual content. Children's visual-attention…

Performance is affected by cognitive learning skills, but also by the reasons people perceive as causes of their successes and failures. People with high achievement needs perceive their successes as caused by their own ability and effort, and their failures as caused by lack of effort. People with low achievement needs blame their failures on…

The purpose of the study was to apply various quantitative and qualitative indices of grammatical complexity proposed by Hunt (1965) to written language samples of hearing impaired students. Hunt studied grammatical structures of normal students at three grade levels, and found that the minimal terminal syntactic unit, or T-Unit, more reliably…

This study is the fourth in a series of studies that have attempted to examine the relationship between two separate aptitude factors--associative memory and reasoning--to various performance criteria in a hierarchical learning task utilizing computer-assisted instruction. Two clear effects seem to emerge from the data. During learning, the…

This study was concerned with children's ability to conserve spatial relationships among objects in different arrangements, in the presence of projected changes in the observer's visual field. The objectives were: (1) to determine the effects of varying types of arrangement and number of objects in the arrangement on perspective ability…

This study was designed to investigate the effects of increasing levels of task complexity on the conditioned emotional response (CER) with human subjects (Ss). Three hypotheses were proposed: (1) the CER would increase as task complexity increased, (2) there would be sex differences between Ss with respect to the interaction between the CER and…
