Presented is the task analysis for "Developing Mathematical Processes, Arithmetic, Book 1: Comparing and Equalizing Objects and Sets." This task analysis consists of identifying the behavioral objectives necessary for comparing and equalizing objects and sets and arranging them in a logical sequence for instruction. The 52 items in this task…

The effects and interactions of 3 variables on concept learning and retention were investigated: (1) method of stimulus presentation; (2) learning process; and (3) intellectual ability. One hundred and forty-four (144) 4th graders were divided into 4 groups, each of which was further subdivided into high, middle, and low intellectual ability…

A survey of the evidence shows that some degrees of malnutrition is relatively widespread among poor children. However, the effects of inadequate nutrition on growth and mental development depend to a large extent on the severity, the timing (pre and postnatal), and the duration of the nutritional deprivation. The data are inadequate on the true…

Certain transitivity relationships formulated from reversible operations were examined. Thirty randomly selected fifth grade students received instructional episodes, developed for each identified behavioral objective and its inverse (on unspecified content), presented via the IBM 1500 Instructional Computer System. It was found that students who…

The 30 sixth and 30 ninth grade students, all of whom attended one rural school district in central Illinois, not only displayed a wider variety of behaviors than reported in the Inhelder and Piaget study (1958) investigating the development of logical thinking in children, but the behavioral components served to fill significant gaps in the…

The ability of 23 educable mentally retarded children (mean chronological age, 9 years) to transfer verbal elaboration techniques to a labeling task was tested following one, two, or no elaboration experiences. An additional 18 retardates were tested in two outside control conditions to identify the effects of reversal experience on acquisition…

The objective of this study was an attempt to clarify the nature of number conservation with number conservation tasks using variations in length, area, and volume. According to Piagetian theory, conservation is attained successively for number, length, area, and, finally, volume. It was hypothesized that success on the number conservation tasks…

The general purposes of a model are discussed, then seven papers are presented which demonstrate several different facets of the problems associated with constructing and using models of mathematics learning. In the first paper, the task addressed concerns how to incorporate developmental psychology into perceptions of what is happening in the…

This study showed that course-acquired knowledge can apparently be kept fresh over long periods by small amounts of properly spaced review activities. (PCB)

The fraction concept was analyzed to yield 16 subconcepts which are hypothesized to be hierarchically ordered. This ordering was tested using subjects in grades 4 through 6, and 18 of 23 dependencies hypothesized were confirmed. (SD)

Examines the individual and cumulative effects on achievement of providing students with objectives, sample test items, and a mastery strategy that included diagnostic testing and remedial instruction. Also investigates the effects of mastery learning on achievement of students with different aptitudes for learning. (Author/GA)

Investigates the ability of secondary school students to discriminate causal explanations from teleological and anthropomorphic explanations (TAE), and explains that a significant improvement in this ability can be achieved by appropriate teaching procedures in a relatively short time. (Author/GA)

The role of affective and associative meaningfulness in the learning styles of Chicanos and Anglos was examined. Chicano and Anglo undergraduates (N=64) were compared on learning of affectively and associatively assessed consonant-vowel-consonant trigrams. Chicanos differed significantly from Anglos in affective learning scale. (Author)

Students were measured on eleven aptitudes from Guilford's structure-of-intellect cube, and randomly assigned to symbolic or figural instructional modes for a unit on functions. Achievement was measured and compared for students with different aptitudes. (SD)

Reviews laws, conditions, and categories of learning and educational theory-building. (SL)
