This study examined whether iron deficiency (ID) in infancy contributes to problem behaviors in adolescence through its influence on poor regulatory abilities in childhood. Chilean infants (N = 1,116) were studied when there was no national program for iron fortification (1991–1996), resulting in high rates of ID (28%) and iron‐deficiency anemia (IDA, 17%). Infants (54% male) were studied at childhood (Mage = 10 years) and adolescence (Mage = 14 years). IDA in infancy was related to excessive alcohol use and risky sexual behavior in adolescence through its effect on poor emotion regulation in childhood. Attentional control deficits at age 10 were also related to both infant IDA and heightened risk taking in adolescence. Findings elucidate how poor childhood regulatory abilities associated with infant IDA compromise adjustment in adolescence. 相似文献

The expression “big data” is ubiquitous in the business world today, but few undergraduate business students have the opportunity to gain practical experience with how new business analytics tools can be used in decision making. This article describes a set of hands‐on labs that prepare students to incorporate streaming data analysis into group research projects. Splunk is used to help students analyze and visualize streaming social media data. An evaluation of student projects and student survey results show that this practical approach of training students to manipulate and visualize big data was largely successful in achieving instructional goals. 相似文献

Recent federal investments in early childhood assessment systems are the result of a national need for developmentally appropriate, psychometrically sound instruments to monitor young children and evaluate the effectiveness of their learning programs. In this paper, we examined the association between teachers’ perceptions of their students at the start of kindergarten and academic achievement in Grade 3 with hierarchical linear modeling using state-level data from nearly 30,000 students. The analyses showed that such an association exists even after accounting for student-level and school-level demographic variables and is moderated by the percentage of free-lunch-eligible students in a given school. Implications of these findings related screening and assessment at kindergarten entry are discussed. 相似文献

A sample of 267 American School Counseling Association members were surveyed regarding their current supervision, desire for clinical supervision, and rating of supervision goals. Although a small minority of respondents indicated that they were currently receiving supervision, a majority of respondents indicated a desire to receive supervision. Factor analysis of ratings of supervision goals resulted in 3 factors related to the foci or learning dimensions described in J. M. Bernard's (1997) Discrimination Model. Recommendations for counselor educators and school counselor supervisors are discussed. 相似文献

This action research demonstrates the answer to this question: How can literacy professors provide effective training in evaluating writing to preservice graduate education students? The study examines writing assessment instruction in the context of a literacy course required of preservice teachers seeking secondary (7–12) certification in content area instruction. Approximately half of the course is devoted to instruction in 3 areas of writing assessment: (1) theory and practice in aspects of holistic writing assessment analysis, (2) methods for designing teachable rubrics, and (3) approaches to creating and sharing written feedback. Student-participants’ written responses to protocols demonstrate learning outcomes in these 3 areas along with their attitudes and the effects of their practice with an authentic set of high school students’ essays. The study demonstrates the effectiveness of this assessment instruction as a part of overall effectiveness in teacher preparation programs at the graduate level. 相似文献

Using structural equation modeling techniques, this exploratory study investigated the differences in the factor structure of academic self‐perceptions in a sample of gifted students and within a general population of students. The factor structure exhibited partial measurement invariance, suggesting that two of the items on the factor work differently in the gifted sample than in the sample from the general population. The gifted sample demonstrated higher academic self‐perceptions than the general school sample and higher self‐reported GPAs than the general school sample. However, the relationship between academic self‐perceptions and self‐reported GPA was invariant across groups. For both gifted students and the general population of high school students, GPA and academic self‐perceptions were moderately and positively related. Therefore, although there are large mean differences between gifted students and the general population of students on the academic self‐perceptions scale, the structure of the relationship between academic self‐perceptions and GPA was similar. 相似文献

The rapid and wide spread of English has given rise to its lingua franca status, which in turn, changes the nature of English and English teaching at the tertiary level. This paper, based on a survey, discusses some of the problems with the current English curriculum used in Chinese universities and proceeds to offer some suggestions for a more appropriate university English curriculum in China in the context of English as an international language. 相似文献

This note discusses, with examples, correct ways of determining the average growth rates of phenomena that grow exponentially, such as typical library collections. Library expenditures also tend to grow exponentially; and because analysis of their growth rates is complicated by the effects of currency inflation, methods of compensating for inflation in the analysis are presented. 相似文献
