In this study, the relationship between differentiated instruction, as an element of data-based decision making, and student achievement was examined. Classroom observations (n = 144) were used to measure teachers’ differentiated instruction practices and to predict the mathematical achievement of 2nd- and 5th-grade students (n = 953). The analysis of classroom observation data was based on a combination of generalizability theory and item response theory, and student achievement effects were determined by means of multilevel analysis. No significant positive effects were found for differentiated instruction practices. Furthermore, findings showed that students in low-ability groups profited less from differentiated instruction than students in average or high-ability groups. Nevertheless, the findings, data collection, and data-analysis procedures of this study contribute to the study of classroom observation and the measurement of differentiated instruction. 相似文献

ABSTRACT This article discusses the transition that publishers have had to make in the process of converting print journals and reference books to an online format. It was originally thought that making content available online would save publishing costs, but the changes made to production cycles and the needs of making content widely available, updated, and housed on online platforms are sometimes more expensive than the print process alone. Publishers have responded with new pricing models, and they are working more closely with libraries to deliver content to a wider audience while competing with search engines and other online content providers. Additionally, publishers have a new responsibility to manage the quality and accuracy of content given that so much information is now available to readers. 相似文献

In this article, an alternative for Tinto’s integration theory of student persistence is proposed and tested. In the proposed
theory, time available for individual study is considered a major determinant of both study duration and graduation rate of
students in a particular curriculum. In this view, other activities in the curriculum, in particular lectures, constrain self-study
time and therefore must have a negative impact on persistence. To test this theory, we collected study duration and graduation
rate information of all—almost 14,000 students—enrolling in eight Dutch medical schools between 1989 and 1998. In addition,
information was gathered regarding the timetables of each of these curricula in the particular period: lectures hours, hours
spent in small-group tutorials, practicals, and time available for self-study. Structural equation modeling was used to study
relations among these variables. In line with our predictions, time available for self-study was the only determinant of graduation
rate and study duration. Lectures were negatively related to self-study time, negatively related to graduation rate, and positively
related to study duration. The results suggest that extensive lecturing may be detrimental in higher education. However, in
the curricula employing limited lecturing considerable energy was spent in supporting self-study activities of students and
preventing postponement of learning. Given our findings, both activities will likely have large pay offs, in particular in
curricula with low graduation rates. 相似文献

The motivations and benefits of educational travel among individuals aged 55 years old and over were examined in this study. A total of 136 older adults enrolled in Elderhostel programs participated in this study and reported their perceived benefits and motivations for engaging in educational travel experiences. Correlation analyses were used to explore relationships between the adults' perceived benefits and motivations. Analyses of variance were conducted and significant differences in adults' motivations for educational travel were found by gender, education level, health, and activity level of the program. The findings from this study are discussed in terms of successful aging, and implications for organizations offering educational travel programs are provided. 相似文献

The problem for this study was the identification of earth science concepts recommended by scholars in earth science for inclusion in the R-12 science curriculum. Three panels of earth science scholars assisted in the study. The third panel was selected in such a manner as to insure that the judgement of the entire memberships of five major professional organizations within the earth sciences would be represented within specified limits. The final concept list contained fifty-two earth science concepts. The claim is not made that the concept list which was developed is a complete list of earth science concepts which earth science scholars believe to be important for inclusion in the K-12 science program; the list is to be regarded as a sample of those concepts which would form a complete list. However, it would seem that due to the method of compiling the list that a majority of the earth science concepts which earth science scholars rate as most important for inclusion in the K-I2 science program would be present. 相似文献

This study examined the computational errors made by 370 educable mentally retarded students on the arithmetic subtest of the Wide Range Achievement Test. There were 233 males and 137 females in the sample, and the ages ranged from 8 to 18. Engelhardt's (1977) error classification was used to identify error types. Retarded students had a lower percent of grouping and inappropriate inversion errors and a higher percent of incorrect operation errors than regular students had in Engelhardt's study. 相似文献
