The present research consisted of a comprehensive evaluation of a hypertext model for teaching process writing at the junior high and high school level. Interests were to determine how two teachers and three different age groups of students used and reacted to the model, specifically, its embedded design features of model stories, note cards, idea buttons, mini-lessons, branching buttons, and cut-and-paste-tools. Results showed applications of the embedded features to vary based on teacher attitudes, feature attributes (e.g., ease of use and appeal), and student characteristics. Older students made more usage of many of the features, but were less positive about the hypertext model given their greater involvement with completing writing assignments rather than with exploring new forms of writing. The implications of the results are discussed regarding the instructional design and classroom implementation of new technologies for teaching process writing strategies.This study was conducted as a doctoral dissertation completed by the first author at the University of Memphis under the supervision of the second and third authors. 相似文献

This paper presents results from an experimental study that examined embedded strategy prompts in digital text and their effects on calibration and metacomprehension accuracies. A sample population of 80 college undergraduates read a digital expository text on the basics of photography. The most robust treatment (mixed) read the text, generated a summary for each page of text, and then was prompted with a metacognitive strategy. The metacognitive treatment received metacognitive strategy prompts only, and the cognitive group implemented the cognitive strategy (summarization) only. A control group read the text with no embedded support. Groups were compared on measures of achievement, attitudes, cognitive load, and metacomprehension and calibration accuracy. Results indicated that a combination of embedded cognitive and metacognitive strategies in digital text improved learner achievement on application-level questions, yielded more accurate predictive calibration, and strengthened the relationship between metacomprehension and performance, all of which are common attributes of an academically successful learner. 相似文献

Responses to questions on demography, knowledge about student fees, attitudes toward collection and distribution of fees, and utilization and satisfaction with 8 specific fee-funded programs were collected by mail survey from a sample of 1,002 University of Colorado (Boulder campus) students stratified by class year, ethnic group, and school. Only one-third paid their own fees, and less than 30% knew the amount of their fees within $5. Only graduate students advocated a cutback in services to obtain a reduction in fees; most students would accept higher fees to fund three new programs. Differences among students in attitudes toward and use of fee-funded services were definite among year subgroups and minimal among ethnic and school subgroups. 相似文献

This project directly involved students in two different models of instructional development. The first model was a Student Consultant program in which faculty selected from a menu of instructional services carried out by students. Typical services included attending class as impartial observers, soliciting feedback from other students on their learning experiences, videotaping class sessions, and evaluating course Web sites. The second model of instructional development was a program of student‐assisted teaching seminars for college faculty. Student Associates helped serve as panelists and facilitators. Assessments of attitudes toward teaching indicated that faculty members viewed both professors and students as collaborators in the classroom as a result of the seminar series. 相似文献

Online lectures have been used in lieu of live lectures in our gross anatomy and embryology course for the past eight years. We examined patterns of online lecture use by our students and related that use to academic entry measures, gender and examination performance. Detailed access records identified by student were available from server logs. Total views per page of lecture material increased over the first six years, then decreased markedly between years seven and eight, possibly due to the recent availability of alternate forms of lecture audio. Lecture use peaked in midafternoon and again in the evening, although some use was seen at all hours. Usage was highest at midweek and lowest on Fridays as might be expected. Individual student's use varied widely from rates equivalent to less than one viewing/page to more than three viewings per page. Overall use by male students was greater than that of females and gender‐specific differences in the daily pattern were seen. Lecture use was correlated to the Medical College Admission Test® (MCAT®) Verbal Reasoning and Physical Sciences scores but not to composite MCAT scores or undergraduate grade point average. Overall use appeared to be driven by scheduled team‐based learning (TBL) sessions and major examinations. Specific subsets of lecture material were most often viewed before related TBL sessions and again during review for examinations. A small but significant correlation between lecture use and examination and course performance was seen, specifically in the male student population. These findings, along with earlier observations, suggest that varied use of online lectures is attributable to multiple factors. Anat Sci Educ © 2012 American Association of Anatomists. 相似文献

This research examined the relationships among students?? academic majors, levels of engagement, and learning outcomes within the context of Holland??s person?Cenvironment theory of vocational and educational behavior. The study focused on the role of student engagement as a mediating agent in the relationships between academic majors and student learning. Drawing on data from a stratified random sample of 20,000 seniors who participated in the 2008 National Survey of Student Engagement, results revealed that students?? academic majors were significantly related to levels of engagement and learning outcomes. Student engagement was also significantly related to learning outcomes. Students?? academic majors generally were not indirectly related to learning outcomes through levels of engagement. An important exception to this result was found for students in Enterprising environments where indirect relationships among Enterprising disciplines and Enterprising learning outcomes were positive, statistically significant, and substantially larger than the direct relationship. 相似文献

Population structure and linkage disequilibrium in elite barley breeding germplasm from the United States 总被引:2,自引:0,他引:2

Cultivated barley is known to have a complex population structure and extensive linkage disequilibrium (LD). To conduct robust association mapping (AM) studies of economically important traits in US barley breeding germplasm, population structure and LD decay were examined in a complete panel of US barley breeding germplasm (3 840 lines) genotyped with 3 072 single nucleotide polymorphisms (SNPs). Nine subpopulations (sp1‒sp9) were identified by the program STRUCTURE and subsequently confirmed by principle component analysis (PCA). Out of the nine subpopulations, seven were very similar to the respective subpopulations identified by Hamblin et al. (2010) which were based on half of the germplasm and half of the SNP markers, but two subpopulations were found to be new. One subpopulation was dominated by six-rowed spring lines from Utah State University (UT) and the other was composed of six-rowed spring lines from multiple breeding programs (USDA-ARS Aberdeen (AB), Busch Agricultural Resources Inc. (BA), UT, and Washington State University (WA)). LD was found to decay across a range from 4.0 to 19.8 cM. This result indicates that the germplasm genotyped with 3 072 SNPs would be robust for mapping and possibly identifying the causal polymorphisms contributing to disease resistance and perhaps other traits. 相似文献
