The nature of the message used by children, 4 1/2 and 6 1/2 year-old, was studied in a spatial description task. Speaker and listener were separated from one another by an opaque screen, and had to exchange information. Speaker were asked to describe a board showing eight objects placed in a room, and listeners were instructed to draw a similar…

The purpose of this study was to explore the use of a cognitive computer tool by undergraduate calculus students as they worked cooperatively on mathematical tasks. Specific attention was given to levels of cognitive demand in which the students were engaged as they completed in-class labs with the assistance of MathCAD. Participants were assigned…

The construct validity of algebra word problems for measuring quantitative reasoning was examined, focusing on an analysis of problem attributes and on the analysis of constructed-response solutions. Constructed-response solutions to 20 problems from the Graduate Record Examinations (GRE) General Test were collected from 51 undergraduates.…

This study examined planning processes and the acquisition of expert problem solving skills among individuals of different expertise on tasks of increasing complexity. Twelve French-speaking adult students of machining (novices) and 12 French-speaking teachers of machining (experts) in Quebec (Canada) were randomly assigned to a simple or complex…

Focusing on what authors can do to facilitate learning from content area textbooks, this report labels authors as "considerate," providing text that readers can understand with a minimum of cognitive effort, or as "inconsiderate," creating text that requires a conscientious, highly skilled effort if readers are to comprehend…

A sample of 48 second grade and fifth grade children, containing equal numbers of high and low ability readers, participated in a study that explored the degree to which oral and silent reading represented the same cognitive process for different age and ability level children. Their reading rates and comprehension scores for both oral and silent…

On the basis of the grammatical theory developed by Noam Chomsky, it is reasonable to presume that the different parts of a sentence may not all be understood with equal facility and speed. One purpose of this study was to determine whether some of the grammatical relations within a sentence were understood more readily than others. Sentences of…

The effectiveness of the Delphi Technique is evaluated in terms of immediate and delayed controlled information feedback (feedback within 5 seconds as compared with a 24-hour delay); and the relationships that exist among measures of integrative complexity, estimations about the time of occurrence of future events, and time delay between task…

This review examined the sequencing and grading of tasks in English-as-a-Second-Language (ESL) task-based learning pedagogy. Recent research on task-based learning has focused on cognition and the role that cognitive processes play in determining the ease or difficulty of any particular task. It is argued that an understanding of the effects on…

Presents the results of a study of the recall performances of developing young readers compared across the three language reception modes of listening, oral reading, and silent reading. The effects of the difficulty of the reading material and of sex differences are discussed. The texts used are appended. (Author/JL)

Results of four experiments show that developmental differences in elaborative conceptual processing at acquisition and retrieval contribute independently to developmental increases in recall. Item identification processes for both words and pictures constrain children's elaborative processing. The constraints are time limited. (RH)

Context effects in test taking were explored, paying attention to the psychological processes that occur during test taking, and modeling context effects for each individual at the item block level. A sample of 279 high school students (140 females and 139 males) was chosen to yield adequate power for detecting interactions. Reading test forms…

A study compared the effects of cognitive complexity on the speech production of 14 advanced non-native speakers of English and 14 native English-speakers. Cognitively simple and complex tasks were distinguished based on text type (narrative versus expository). Subjects read one narrative and one expository text in separate sessions, then wrote…

A multiple choice achievement test was constructed in which both cognitive level and degree of abstractness were controlled. Subjects were 75 students from a major university in the Southwest. A group of 13 judges, also university students, classified the concepts for degree of abstractness. Results indicated that both cognitive level and degree…

The question of developmental synchrony within the concrete operations period described in Piagetian literature was investigated. The idea of synchrony has been challenged by Brainerd's initial groupement research, which indicated a two-dimensional structure, corresponding to class operations and relational operations. A review of the literature…
