Discussion is one form of active learning, which has been linked to better learner outcomes. Little is known about the relationship between active learning through discussion and learner outcome in the online environment. Here, we construct an index of active learning online that includes the number of postings a student has read, the number of…

The authors investigated the performance of 172 Grade 4 students (9 to 10 years) over 12 months on a 36-item test that comprised items from 6 distinct graphical languages (e.g., maps) commonly used to convey mathematical information. Results revealed (a) difficulties in Grade 4 students' capacity to decode a variety of graphics, (b) significant…

Exposure to print is a significant predictor of vocabulary growth and declarative knowledge in normally achieving readers (Stanovich, West, & Harrison, 1995). Research has also shown that initial differences in print exposure can be used to predict differences in reading comprehension in children studied ten years after initial assessment…

Purpose: This study investigated the relationship between hearing loss and memory and attention when nonverbal, visually presented cognitive tests are used. Method: Hearing loss (pure-tone audiometry) and IQ were measured in 30 participants with mild to severe hearing loss. Participants performed cognitive tests of pattern recognition memory,…

Context: Few studies have examined the prevalence of overweight status and physical inactivity among children and adolescents living in rural America. Purpose: We examined urban and rural differences in the prevalence of overweight status and physical inactivity among US children. Methods: Data were drawn from the 2003 National Survey of…

The study in this article employed a multidimensional (behavioral, emotional, and cognitive) construct of school engagement to examine its relationship to school achievement in mathematics across the five major racial groups. The sample included 115 American Indians, 486 Asians, 1,551 Blacks, 1,682 Latinos, and 7,554 Whites who participated in the…

An investigation of the effects of randomly missing data in two-predictor regression analyses is described. The differences in the effectiveness of five common treatments of missing data on estimates of R-squared values and each of the two standardized regression weights is also investigated. Bootstrap sample sizes of 50, 100, and 200 were drawn…

Analyzes data from lengthy profile questionnaires completed by 78 managers and 407 of their subordinates and examines how five different management styles are related to various aspects of the contingent situation. (Available from Subscription Section, American Psychological Association, 1200 Seventeenth Street, N.W., Washington, D.C.; $30.00…

Many data analysis problems in psychology may be posed conveniently in terms which place the parameters to be estimated on one side of an equation and an expression in these parameters on the other side. A rule for improving the rate of convergence of the iterative solution of such equations is developed and applied to four problems. (Author/RC)

A study was conducted which partially tested the validity of assumptions of the Coordinated Management of Meaning (CMM) based model of communication competence. Two research questions were explored: (1) how well can a CMM-based model predict an individual's perceived communication competence in a given context? and (2) how is an individual…

The behavior of two real-time computer simulation models of melody recognition was compared with the performance of human subjects in this study. One of the models, INT1, recognized melodies by comparing specific intervals with stored intervals. The other model, CONT1, performed by comparing the contour of the stimulus melody with an array of…

In almost all applications of measurement there is some sort of response by a human subject. Almost always, the response scale is ordinal, but almost always it is treated as if it were an interval measure. Methods for treating data ordinally are currently being developed in three areas: ordinal analysis for questionnaire responses, ordinal…

In this article the results from six states in Australia involved in a cross-national analyses of an IEA Science Project are regarded as replications, on the basis of which general statements are made about learning conditions associated with the performance in science of Australian students.

Experimental studies indicate that the primary determinant of changes in sexual and aggressive behavior following alcohol consumption is expectancy. Multiple regression analyses were performed on the responses of 100 college students to an alcohol-expectancy questionnaire to determine how expectations for sexual and aggressive behavior following…
