This article reports on a naturalistic study of online and CD-ROM databases to identify design characteristics that are important to high school students' use of these information resources for higher-level learning as well as for information access and retrieval. Primary data collection techniques were interactive observations of 92 students and informal interviews with 54 students, 4 teachers, and the school library media specialist. The article presents an inventory of specific problems students experienced while using 7 CD-ROM and 18 online databases and discusses implications for database design based on the study results. By showing how the lens of instructional systems design can be applied to the study of a specific information technology, this article provides a new perspective on database design and suggests how electronic information resources can be designed to promote higher-level learning through enhancing students' opportunities to process, evaluate, and apply the information they retrieve from these resources.The paper on which this article was based received the 1993 AECT Special Research Award for qualitative research. 相似文献

Homeschooling Is Not Just About Education: Focuses of Meaning 总被引:1,自引:0,他引:1
This article explores the meanings parents attribute to homeschooling. The literature reveals two main approaches to this subject: a view of homeschooling as a pedagogical practice and a holistic perspective. Employing qualitative methodologies, we administered in-depth interviews to 30 mothers who engaged in homeschooling in Israel, in order to gain a better understanding of what homeschooling meant to them. Analysis of the interviews indicated that the participants attributed diverse meanings to homeschooling. These represented many themes, which were gathered into four super-themes: control, lifestyle, family, and child. The first two themes were emphasized more often than the latter two. 相似文献

Two instructional experiments used randomized, controlled designs to evaluate the effectiveness of writing instruction for
students with carefully diagnosed dyslexia, which is both an oral reading and writing disorder, characterized by impaired
word decoding, reading, and spelling. In Study 1 (4th to 6th grade sample and 7th to 9th grade sample), students were randomly
assigned to orthographic or morphological spelling treatment but all students were taught strategies for planning, writing,
and reviewing/revising narrative and expository texts. Both treatments resulted in improvement on three measures of spelling
and one measure of composition. Morphological treatment resulted in better improvement in spelling pseudowords, whereas orthographic
treatment resulted in better improvement in rate of reading pseudowords. In Study 2 (4th to 6th grade sample), students were
randomly assigned to explicit language treatment (phonological working memory + phonological-orthographic spelling + science
report writing training) or nonverbal problem solving treatment (virtual reality-based computer simulation, drawing maps,
and building clay models). Both treatments used science content material and resulted in significant improvement in spelling
and reading pseudowords (accuracy and rate). The surprising finding was that hands-on, engaging science problem solving led
to more improvement in phonological working memory than did specialized phonological instruction. Only when spelling instruction
emphasized orthography or morphology (Study 1) did real word spelling improve.

After explicit spelling instruction, low achieving second grade spellers increased the number of correctly spelled words during composing but differed in response trajectories. Class 1 (low initial and slow growth) had the lowest initial performance and improved at a relatively slow rate. Class 2 (high initial and fast growth) started higher than Class 1 but below Class 3 and improved at the fastest rate. Class 3 (highest initial but slow growth) had the highest initial performance but improved at a rate similar to Class 1. Class 3 differed from Classes 1 and 2 on orthographic coding. Classes 1, 2, and 3 differed on rapid automatic naming (RAN letters). Spelling instruction plus supplementary activities to improve orthographic coding in working memory and rapid, automatic coordination of phonological and orthographic codes may facilitate transfer of spelling learned during instruction to applying that spelling knowledge during independent composing. 相似文献

This essay stems from the 35th annual C. H. McCloy Research Lecture at the 2015 SHAPE America National Convention &; Expo in Seattle, WA. The lecture series has 2 main aims. First, it provides an annual forum for a contemporary scholar to delve deeply into her/his work and to share that work with her/his peers. Second, it is an enduring tribute to the pioneering work and influential career of Charles Henry McCloy (March 30, 1886–September 18, 1959), research professor emeritus at the University of Iowa. This essay is composed of 6 sections: a prologue, a biography of McCloy, my autobiography, the fundamental premises and overarching aims of my work, a summary of my research contributions aimed at promoting inclusive physical activity, and an epilogue. The entire article is built around the construct of maps, mechanics, detours, and traveling companions. Paradigm shifts and insights are unraveled as the work unfolds and becomes increasingly integrated. Rarely does a scholar have the chance to provide a narrative of this nature, and it is hoped that this essay will inspire others to discover their own scholarly pathways and to contextualize and reflect on their contributions for the greater good of the field of kinesiology and society. 相似文献

Research on citizens’ inattentiveness to political news has built a theoretical base for understanding political judgment in the American electorate. The research, however, has a strong cognitive orientation with surprisingly little attention to the dynamic interaction between emotional and attentional factors. To broaden our understanding of these potential emotional influences, we assessed levels of enthusiasm, anger/aversion, and anxiety in response to brief summaries of 50 news stories of diverse character and provenance selected to be representative of quotidian news. The analysis reveals dramatic variation across news stories and across subjects responding to the same story on all 3 emotional dimensions. We also examine an unexpected inverse correlation between education and level of emotional response to news. 相似文献

The purpose of the study was to explore how features of parent–child extra-textual talk during information book-sharing might vary across different socioeconomic backgrounds, and to determine if certain interactional patterns might mediate their effects on children's receptive and expressive vocabulary development. Sixty parents and their 5-year-old children were audio-recorded reading an unfamiliar information book in their home. Holistic coding on six parent and two child engagement scales, examining low to high cognitive demanding talk was conducted. Results indicated that lexical richness and contingent responsiveness positively predicted receptive and expressive vocabulary. Further, contingent responsiveness appeared to mediate the influence of socioeconomic status on children's receptive and expressive vocabulary, suggesting that positive environmental contexts and supportive parent–child interactions can have a powerful influence on children's development. 相似文献
