A specialized vector used to interpret rejected multivariate single sample hypotheses, introduced in an earlier article by the writer (EJ 097 103), is shown here to be equivalent to the vector that would be obtained if discriminant analysis techniques were to be applied to a single sample problem.

Kendall's S is often used for measuring magnitude of bivariate association in social and behavioral research. This nomogram permits a research analyst to make rapid and accurate evaluation of the statistical significance of S without recourse to formulae or computations in all except borderline cases.

When analyzing a squared multiple correlation coefficient, an investigator may be interested in determining whether it is above or below a known constant, rather than testing the null hypothesis. This paper gives the sample sizes required for answering this question when indifference zone formulation of the problem is used. (Author/BW)

A walk through Milne's Enchanted Forest leads to an unexpected encounter with hypothesis testing.

Many attempts are currently being made to develop Aural-Oral Communicative skills in English at school level, but it remains a difficult task for the teachers of English. There are a lot of readymade cassettes available in the market but they have hardly served the purpose. Admittedly, cassettes help and yield better results for learners, subject…

This study describes assessment results from the Distance Education Mentoring Program (DEMP) at Purdue University Calumet, Indiana, USA. The program, sponsored by the university's Vice Chancellor for Academic Affairs, was made available to all teaching faculty who wished to become proteges and develop their skills at teaching online courses. The…

There is a growing awareness that science education should center not just on knowledge acquisition but developing the foundation for lifelong learning. However, for intentional learning of science to occur in school, out of school, and after school, there needs to be a motivation to learn science. Prior research had shown that students'…

Students from six countries--Australia, Japan, Mexico, Sweden, Taiwan, and the United States--recalled the extent to which their best or worst professors used various forms of communication that have been associated with effective teaching. Across cultures, best professors were perceived to employ more nonverbal expressiveness, relaxed movement,…

Educators are concerned about the loss of instructional time resulting from student suspension. The right to obtain a free appropriate public education must be balanced with the myriad of discipline and school safety issues. The loss of instructional time due to disciplinary sanctions negatively impacts student achievement, possibly resulting in…

We examined the possibility that teams composed primarily of individuals with personality characteristics conducive to team creativity (e.g., high extraversion, high openness to experience, low conscientiousness, high neuroticism, low agreeableness) would show synergistic increases in creativity when they experienced high levels of "team creative…

The striatum is considered to mediate some forms of procedural learning. Complex dynamic control (CDC) tasks involve an individual having to make a series of sequential decisions to achieve a specific outcome (e.g. learning to operate and control a car), and they involve procedural learning. The aim of this study was to test the hypothesis that…

As the transition to adulthood becomes more protracted and less orderly, fewer young people occupy adult roles and experience the social control associated with these roles. One might therefore expect behaviors associated with the teenage years to spill over into older age groups, reflecting postponed entrance into full social adulthood. We test…

The present study investigated whether facial expressions modulate visual attention in 7-month-old infants. First, infants' looking duration to individually presented fearful, happy, and novel facial expressions was compared to looking duration to a control stimulus (scrambled face). The face with a novel expression was included to examine the…

Children personally construct explanations of natural phenomena, some of which differ from currently accepted scientific explanations. The replacement of personal explanations with scientific explanations, as well as the development of concrete, formal, and post-formal reasoning patterns, requires self-regulation in which alternative explanations…
