The impact of instructional practices in Grades 1 and 2 on reading and spelling achievement in high poverty schools 总被引:1,自引:0,他引:1

The objective of this investigation was to examine how instructional practices in 107 first- and second-grade classrooms in 17 high poverty schools moderate the impact on literacy outcomes of literacy-related skills students bring to the classroom. Ratings of teaching effectiveness and time allocation to literacy activities were obtained. Twenty time allocation variables were reduced into seven patterns of literacy activities that were examined as predictors of reading and spelling outcomes. Students’ initial reading ability and interactions of teaching effectiveness ratings by time allocation components predicted reading and spelling outcomes. Discussion centers on immutable versus flexible views of reading development and analytic approaches to examining instructional practices. 相似文献

Face‐to‐face education and distance education, viewed as differing sets of organisational provisions for the fostering of learning, emphasize different kinds of learning processes, and depend upon somewhat different psychological properties in learners. Nonetheless, all practical learning settings, whether they are labelled ‘school’, ‘adult education’, ‘distance education’, or something else, involve a mixture of face‐to‐face learning and distance learning. The psychological difference between the two kinds of setting is thus note purely qualitative in nature, but is also quantitative: for instance, certain learner characteristics which are useful in face‐to‐face learning (discussed in detail in the body of the present paper) are indispensible for distance learning, while certain processes which are at the heart of distance learning (also dis‐cusssed in detail later) are often given little emphasis in face‐to‐face settings, although they are in principle possible and even desirable there. The question thus arises of whether it would not be desirable to give more emphasis in face‐to‐face settings to psychologically desirable aspects of distance learning. 相似文献

This paper is concerned with those who display positive indicators on tests for dyslexia but seemingly do not have any severe
literacy problems. A case study is presented by way of illustration. On the basis of data from the British Births Cohort Study
(12,905 10-year-old children), it was found that some seemingly normal achievers who showed signs of dyslexia (N=422) obtained
different results on five measures associated with dyslexia than did other normal achievers without such signs (N=4,998).
The measures used were: underachievement at word recognition; and underachievement at spelling, reading comprehension, pseudoword
reading, and mathematics. The proportion of boys to girls in the groups was also noted. It is suggested that these were cases
of mild dyslexia, who, on the basis simply of reading and spelling tests, might escape detection. The consequences for the
concept of dyslexia are discussed, and it is suggested that the needs of dyslexics with only mild literacy problems should
not be overlooked. 相似文献

The positive impact of undergraduate research experiences on students’ post-secondary success is well-documented. However, these conclusions are drawn from undergraduate students who already participate; very little research has explored the pathways by which students enter these experiences. Using data from a multi-institutional survey, we examined students’ reasons for participating and differences across institutions and demographic groups. Overall, students cited social and experiential reasons as key motivators for participation and a perceived lack of research readiness as a key barrier. Differences were also found across academic year. Implications from this study address issues of access, preparation, and institutional policies around undergraduate research. 相似文献

Anatomy education in most African countries is limited by an insufficient number of cadavers for students to undertake dissection. This already significant shortage is exacerbated by an increasing number of medical schools and students. Virtual dissections are impractical in alleviating such a shortfall in African anatomy education, and further cadaver supply is challenged by unethical and dubious sources. This study was designed to assess the knowledge, attitudes, and practice of whole body and organ donation by Nigerian anatomists with the aim of finding solutions to the problems associated with the availability of cadavers in Nigerian medical schools. Out of 46 anatomists that participated in the survey, only 23.9% would consider donating their whole bodies and 60.9% their organs. More than 95% of respondents did not believe that body bequests could become the sole source of cadavers for anatomic dissection in Nigeria. Age and gender were not statistically significant in the choice of being a body or organ donor. The unacceptability to one's family members regarding body donation was the major reason for respondents' unwillingness to make a whole body donation. None of the 14 medical schools sampled in this study have yet instituted a body registration and donation program. The anatomists showed a high level of knowledge and awareness of body bequest programs, which were not reflected by their attitudes and practice. The authors recommend proactive measures aimed at improving the perception and attitudes of Nigerian anatomists. Anat Sci Educ. © 2012 American Association of Anatomists. 相似文献

In this section of Resonance, we invite readers to pose questions likely to be raised in a classroom situation. We may suggest strategies for dealing
with them, or invite responses, or both. “Classroom” is equally a forum for raising broader issues and sharing personal experiences
and viewpoints on matters related to teaching and learning science. 相似文献

Measuring overall service quality (OSQ) is gaining prominence in higher education due to the increased competition among engineering education institutions (EEIs) and growing awareness about value for money among the public. Determination of OSQ on certain institutional aspects is done by various agencies throughout the world. Each system uses a different set of weighted indicators to measure the overall service quality of institutions. Five service quality factors, namely professionalism, integrated education, facilities, responsiveness and empathy are considered in the study. Trapezoidal fuzzy numbers are used to determine the aggregate weights of the factors to handle the vagueness present in the linguistic values of the stakeholders’ subjective opinions. Final weights of the factors are assessed by taking the distances of each factor between Fuzzy Positive Ideal Rating and Fuzzy Negative Ideal Rating. An illustrative study is presented to determine the OSQ of EEIs. The results help to focus on the factors which need immediate attention to enhance the quality of EEIs. 相似文献
