A nationally representative sample of eighth-graders were first surveyed in the spring of 1988. A sample of these respondents were then resurveyed through four follow-ups in 1990, 1992, 1994, and 2000. On the questionnaire, students reported on a range of topics including: school, work, and home experiences; educational resources and support; the…

In 2 experiments, 280 college students studied animations depicting a mechanical operation with concurrent oral narration of the process, successive animation and narration, animation alone, narration alone, or no instruction (the control group). Results are consistent with a dual coding model of retention and problem solving. (SLD)

The observational study of effective instructional processes in kindergarten by DeVries and others is critiqued. It is maintained that (1) the study takes a narrow approach to constructivism that does not reflect current thinking; (2) there are flaws in the coding system used; and (3) the understanding of instructional issues involving minority…

Cryptography is the science that renders data unintelligible to prevent its unauthorized disclosure or modification. Presents an application of matrices used in linear transformations to illustrate a cryptographic system. An example is provided. (17 references) (MDH)

Presents media literacy research of eighth-grade students to determine the level of recognizing and understanding visual and nonvisual codes that make up motion-picture stories. Study focused on rhetoric of the film medium: trust, confidence and belief in films among children is very high; if this trust coincides with ignorance of media codes,…

Encoded Archival Description (EAD) can be seen to have reached maturity as the global data structure standard for the electronic representation of archival finding aids. One factor responsible for this success, flexibility, is now being questioned as it has led to a great deal of divergent practice. This article discusses the attempt to tighten…

This study investigates how different encoding strategies affect retention of Chinese characters (words) as measured by recall of the sound and meaning of the characters. Three types of encoding strategies were investigated during character learning: rote memorisation (shallow processing), student self-generated elaboration, and instructor-guided…
