Children's learning from television was studied in 343 fourth, sixth, seventh, and eighth grade students who viewed an edited version of a television program and took a posttest. It was hypothesized that children would learn more plot-relevant information (central learning material) as they moved from concrete operational to formal operational…

This paper gives a broad descriptive account of some activities that the author has designed using Sketchpad to develop teachers' understanding of other functions of proof than just the traditional function of 'verification'. These other functions of proof illustrated here are those of explanation, discovery and systematization (in the context of…

This report, the forth in a series from the spring 1998 national survey, "Teaching, Learning, and Computing," examines teachers' survey responses that describe the frequency with which their teaching practice involves those five types of activities and the frequency with which their practice involves more traditional transmission and…

A study of the relationship between the quantity of writing assignments and writing apprehension involved 352 college students enrolled in 20 classes in eight discipline areas. Writing apprehension was measured by using the Daly-Miller writing apprehension inventory as a pretest and posttest. Tasks involving learning-centered writing (writing…

A 16-week study to investigate the effects that two methods of teaching writing had on writing apprehension and on overall quality and length of student writing involved over 100 college freshmen enrolled in English Composition classes. Except for the methods of writing instruction, both control and experimental group conditions were held…

This final study in a series reports the investigation in detail of the sex-related differences in the mathematics achievement of sixth grade students. Students were stratified in four intelligence levels with 91.5, 101.5, and 111.5 IQ as cutpoints. Twenty computation scores and eight contemporary mathematics scores were derived from the…

This publication discusses the use of intensive teaching methods for language instruction, also known as suggestopedia ("suggestopaedy"). The theory of suggestopedia, various methods developed from the theory, and their applications are described. A description of Lozanov's suggestopedic method precedes a discussion about the various…

This study examined the development of the rational number concept as a ratio. Preliminary to the description of the study is an introduction discussing constructivism and equilibration. The study itself tests whether equilibration theory holds, and if so, what is the nature of its "phases" and whether these are found at each of the "periods" of…

ANOVA and Profile analysis were employed to compare the computational skills of high and low ability sixth graders during a decade of efforts to individualize instruction. Comparison of lowest ability subgroups demonstrated no differences with statistical significance in their computational skills. There were statistically significant differences…

Fifty-eight studies relating to the "knowledge gap" hypothesis (a theory that correlates public knowledge to educational level and mass media exposure) are examined in this report. In the opening sections, the theory is defined, and the early information diffusion studies and public opinion polls that led to its formulation in 1970 are…
