In decoding a text, one chooses the interpretation involving maximal redundancy, selecting meanings that are most likely and least surprising in the relevant context. Clues for this selection of meanings are gathered from phonetic, phonemic, morphological, syntactic, lexical, and stylistic levels. In disambiguating third-person-pronoun references…

A discussion of pragmatic choice in the use of the possessive pronoun or indefinite article (e.g., "I broke my finger" versus "I broke a finger," and "My leg hurts" versus "A leg hurts") looks at the constructions in the light of a theory of division of pragmatic labor that suggests a binary system of…

The concept of a qualitative model provides a unifying perspective for understanding how expert systems differ from conventional programs. Knowledge bases contain qualitative models of systems in the world, that is, primarily non-numeric descriptions that provide a basis for explaining and predicting behavior and formulating action plans. The…

Pictures abound in history classrooms and teachers use them in many different ways. They add--often literally--some colour to the past, helping us to imagine what different worlds were like. Pictures can be used quite legitimately in this way to fire imagination and stimulate interest. But we can also use them to develop important skills of visual…

Today's technology has reached new heights that have not been fully implemented. One of the areas where technology has not yet reached its full potential is in education. This study examined the effects of concreteness of location names and contiguity of location names with textual information on learning from computer-based reference maps. The…

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…
