Achievement effects of embedded multimedia in a success for all reading program.

Embedded multimedia refers to teaching methods that embed video content within teachers' lessons. The research of Mayer and others has suggested that multimedia instruction can enhance learning by using the capacity of both visual and verbal memory systems. The present study is an evaluation of embedded multimedia in a year-long randomized clinical trial comparing 1st graders who learned beginning reading through the Success for All program either with or without embedded, brief video components. A study involving 394 first graders in 10 high-poverty schools found significant positive effects on the Word Attack scale, controlling for pretests, in hierarchical linear modeling analyses, with school as the unit of analysis. The results provide partial support for the utility of embedded multimedia as a component of beginning reading instruction. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The promise of multimedia stories for kindergarten children at risk.

This research focuses on the ability of book-based animated stories, when well designed and produced, to have positive effects on young viewers' narrative comprehension and language skills. Sixty 5-year-olds, learning Dutch as a 2nd language, were randomly assigned to 4 experimental and 2 control conditions. The children profited to some extent from repeated encounters with a storybook with static pictures but more from repeated encounters with the animated form of the story. Both story formats were presented on a computer screen; both included the same oral text spoken in the same voice but the animated story was supplemented with multimedia features (video, sounds, and music) dramatizing the events. Multimedia additions were especially effective for gaining knowledge of implied elements of stories that refer to goals or motives of main characters, and in expanding vocabulary and syntax. The added value of multimedia books was strengthened over sessions. In a group from families with low educational levels who were lagging in language and literacy skills, multimedia storybooks seem to provide a framework for understanding stories and remembering linguistic information.

Using hypertext to facilitate nurse education

The increased use of both multimedia and the World Wide Web for nurse education necessitates critical examination of the use of hypertext in nursing education. The use of hypertext and multimedia have the potential to revolutionize teaching and learning generally, and have a significant impact on nursing specifically. This article discusses hypertext use in nurse education and incorporates an examination of cognitive theories to identify specific hypertext design strategies customized for nursing user groups. Particular attention is directed to the application of cognitive flexibility theory to hypertext design for nurse education, highlighting the representation of both complex clinical situations and human physiology. The article concludes with a discussion of the potential uses of hypertext as a means of accessing information by nurses in clinical practice.     

Constraints on the selection of auditory information.

Four experiments were conducted to determine whether or not (a) selection of auditory information may be guided separately by location and frequency channels and (b) auditory attention is allocated to spatial locations and frequency regions or to auditory objects (i.e., streams). In Experiment 1, listeners were to categorize tones by location or frequency. In Experiments 2A and 2B, target identification was examined as a function of its similarity to a precue. In Experiment 3, the time required to detect a target embedded within a sequence of distractor tones was examined. In all experiments, performance depended on both location and frequency information even if 1 of these features was completely irrelevant with respect to the task. Results indicate that selection of auditory information is accomplished by an attentional template normally defined by both location and frequency parameters.

Does language matter in multimedia learning? Personalization principle revisited.

This study examines one of the design principles of multimedia learning in a context dissimilar to the one in which it was originally tested. Personalization principle states that the amount of learning increases when the style of language is informal and conversational. In an attempt to uncover the relationship between learning and language styles with varying degrees of personalization and formality, 89 college students were tested with computerized instructional content composed in 1 of the 3 styles: personalized informal, personalized formal, and neutral–formal. The materials consisted of a short text on stellar death with illustrative pictures and animation. The visuals and text were identical for all groups except for additional expressions for personalization and minimal structural changes to evoke a conversational style in 2 of the testing conditions. After reading in 1 of the 3 conditions, the participants were asked retention and transfer questions. The participants also rated the computer program for interest, difficulty of the material, and their motivation for its style. The findings were generally consistent with the predictions of the cognitive theory of multimedia learning except for the effect size for retention. Implications for multimedia design guidelines in varied educational and linguistic contexts are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Use of Multimedia and the World Wide Web in Civil Engineering Learning

The case study method, which has been proven to be a very useful learning tool, can be further enhanced with the use of multimedia and the World Wide Web. This paper demonstrates multimedia and Web-based enhancement with the design and construction of a port, a large-scale civil engineering project. The main purpose was to create an educational tool that brings into the classroom a “real-life” design and construction problem, including the construction field, operation of equipment, and details of construction methods. This enables civil engineering students to better understand the details of the planning, design, and construction of a complicated project. Furthermore, through the use of evaluation tests, feedback on the students’ understanding of the case study can be provided to both the students and the educator. This application can be expanded beyond an academic environment for use as a learning tool in a business environment, which may be especially beneficial for new engineers.     

Evaluation of auramine genotoxicity in primary rat and human hepatocytes and in the intact rat

Auramine, a dye previously found to be a liver carcinogen in both mice and rats, was evaluated for its DNA-damaging and clastogenic activities in primary cultures of rats and human hepatocytes and for the induction of DNA single-strand breaks in the liver and urinary bladder mucosa of intact rats. A similar dose-dependent frequency of DNA fragmentation was revealed by the alkaline elution technique in metabolically competent primary cultures of both rat and human hepatocytes exposed for 20 h to subtoxic concentrations ranging from 10 to 32 microM. In contrast, neither rat nor human hepatocytes displayed an increased frequency of micronuclei after a 48-h exposure to the same auramine concentrations. In rats given a single oral dose of 125, 250 or 500 mg kg-1 auramine, the Comet assay revealed a significant increase in the frequency of DNA lesions in the liver and in the urinary bladder mucosa, the effect being slightly more marked in the liver. Taken as a whole and compared with previous findings, these results suggest that auramine is biotransformed into reactive species in target organs of both rats and humans, and that this dye might play by itself the main role in the increased incidence of bladder cancer which has been judged as causally related to its manufacture.
