This study examined the extent of inferencing in adolescents' and young adults' interpretations of three-minute video segments taken from prime-time drama series and from rock music videos. Results confirmed that the less structured music video segments resulted in higher level inferencing than prime-time dramas. (Author/LMO)

The use of the arc-sine transformation in analysis of variance can lead to difficult inference situations and pose problems in interpretation. It can also produce tests of noticeably lower power when the null hypothesis is false, and is not recommended as a standard tool. Simulated illustrations are provided. (Author/GDC)

In educational research, rigid distinctions between the relative merits of quantitative research often rest on positivistic dogma. In contrast, post-positivistic thought eliminates the intractable problem engendered by positivistic epistemology of a forced choice between value-laden and value-free research methods. (KH)

Explains five strategies for teaching reading comprehension: (1) imaging or visualizing; (2) paraphrasing; (3) questioning and inference; (4) prereading; and (5) metacognitive strategies. (SRT)

Investigates effects of illustrations on 11-year-olds' comprehension of abstract and concrete passages. Reveals no significant effects due to the illustrations, although ability effects were found for literal, inferential, and total comprehension. (DF)

Annually since 1995, the National Youth Gang Center (NYGC) has conducted the National Youth Gang Survey (NYGS) of law enforcement agencies across the United States regarding the presences and characteristics of local gang problems. This Fact Sheet summarizes NYGS findings from the 2004 survey. The nationally representative sample included the…

A student's understanding of a problem before he or she solves it is a critical component of successful problem solving. This understanding is based on how a problem is represented; that is, whether a problem is understood in terms of principles or solution methods or whether the focus is on features that are irrelevant to its solution. In this…

Bootstrap analysis, both for nonparametric statistical inference and for describing sample results stability and replicability, has been gaining prominence among quantitative researchers in educational and psychological research. Procedurally, however, it is often quite a challenge for quantitative researchers to implement bootstrap analysis in…

Used latent class analysis to test statistically Siegler's rule assessment methodology, the number of rules needed to fit a set of data. Found that rules can be identified, that some are different from those proposed by Siegler, the correct rule is not acquired by subjects, and that the rules in the transitional period are difficult to identify.…

Examines potential problems in the use of inferential statistics for single population proportions, differences between two population proportions, and quotients of two population proportions. Discusses hypothesis testing versus interval estimation. Emphasizes the importance of selecting the appropriate formula for the standard error and…

Discusses creativity, play, and nonconformity in children, including the illusion of thought disorder or abnormality, and aspects of everyday creativity, health, and survival. Describes creative divergence, chaotic amplification, the evolution of information, and primitive cognitive processes. Concludes with a discussion of cognitive styles,…

Research has shown that attributional styles are affected by the attributor's culture, inferential goals, and level of cognitive processing. This study compares the attributions made in sports articles and editorials of newspapers published in Hong Kong and the United States. Implications for the mixed model of social inference are discussed. (LSR)

Investigates relations among students' interest in texts, self assessments, and comprehension performance. States that 31 college students read expository texts and--after providing an interest rating and a confidence rating in answering inferences generated from passages on domains--rated texts and completed true/false comprehension questions.…

Distinguishes two conceptions of sample and sampling that emerged in the context of a teaching experiment conducted in a high school statistics class. Suggests that the conception of a sample as a quasi- proportional, small-scale version of the population is a powerful one to target for instruction. (Author/KHR)

Presents and discusses examples that illustrate the nature and scope of elementary and middle school students' reasoning when they are faced with tasks that involve making inferences and predictions from data. Shows that the range in thinking is not so much dependent on age as on the experiences students have in data exploration. (KHR)
