The rate at which 266 boys and girls ages 5 to 7 years old were victimized by peers was observed on multiple occasions in kindergarten and first grade. Individual differences in victimization were observed at kindergarten entry and in growth over the subsequent 2 years. Victimization increased for some children but decreased for others. Growth in victimization was reciprocally related to growth in teacher-reported antisocial and depressive behavior for boys. For girls, kindergarten victimization was related to growth in parent-reported antisocial behavior, teacher-reported depressive behavior to growth in victimization, and growth in victimization to parent-reported depression. At a short-term group level, antisocial behavior had a lagged suppressive effect on victimization for boys but a facilitating effect for girls. 相似文献
On 23 June 2003, the Supreme Court of the United States issued two rulings on the constitutionality of race preferences in university admissions. The cases in question both involved the University of Michigan and were designated Gratz v. Bollinger and Grutter v. Bollinger. Academic Questions' editors subsequently invited five scholars to address the meaning and significance of those decisions. 相似文献
Teachers are central to providing high-quality science learning experiences called for in recent reform efforts, as their understanding of science impacts both what they teach and how they teach it. Yet, most elementary teachers do not enter the profession with a particular interest in science or expertise in science teaching. Research also indicates elementary schools present unique barriers that may inhibit science teaching. This case study utilizes the framework of identity to explore how one elementary classroom teacher’s understandings of herself as a science specialist were shaped by the bilingual elementary school context as she planned for and provided reform-based science instruction. Utilizing Gee’s (2000) sociocultural framework, identity was defined as consisting of four interrelated dimensions that served as analytic frames for examining how this teacher understood her new role through social positioning within her school. Findings describe the ways in which this teacher’s identity as a science teacher was influenced by the school context. The case study reveals two important implications for teacher identity. First, collaboration for science teaching is essential for elementary teachers to change their practice. It can be challenging for teachers to form an identity as a science teacher in isolation. In addition, elementary teachers new to science teaching negotiate their emerging science practice with their prior experiences and the school context. For example, in the context of a bilingual school, this teacher adapted the reform-based science curriculum to better meet the unique linguistic needs of her students.
Proportional reasoning is the basis for most medication calculation processes and is fundamental for high-quality care and patient safety. We designed a simulated Medication Mathematics (siMMath) environment to support proportional reasoning in transitioning via concreteness fading between two mediators. The first mediator is simulated nursing tools of medication preparation. The second is a ratio-table setup which is used as a goal representation, which enables one to spatially hold in place different quantities in their relative proportion. We conducted a two-part study with nursing students. Part 1 was a quasi-experimental pretest–intervention–posttest design assessing the effectiveness of learning, by evaluating four categories of medical calculation questionnaire items (solid medications, unit conversion, concentrations, infusion rates). We used the Noelting proportional reasoning test to evaluate the generalizability and abstraction of proportional reasoning. Part 1 included an experimental group (n = 96) learning with siMMath, and a comparison group (n = 73) learning with an equation-based lecture approach. Part 2 employed a case study design to characterize the learning process. The experimental group’s learning gains were significantly higher than the comparison group’s for the two most challenging categories of the medication calculation problems questionnaire, namely concentrations and infusion rates. Furthermore, the experimental group’s learning gains were significantly higher than the comparison group’s for formal operational reasoning on the Noelting test. Students who used a ratio-table setup scored significantly higher on the Noelting posttest questionnaire. Nursing students who learned with the siMMath environment overcame difficulties in proportional reasoning to the highest levels and extended this understanding to other contexts. 相似文献
In recent years, the application of Information Technologies (IT) has fostered a tremendous growth in e-learning courses at colleges and universities in the United States. Subsequently, some colleges and universities have reported dropout rates of over 60% in e-learning courses. This research investigated persistence in e-learning courses of 187 college student-athletes. To predict the persistence of college student-athletes enrolled in e-learning courses, a conceptual model was proposed and assessed based on students' factors. The factors investigated included students' attitude toward computers, students' intrinsic and extrinsic motivation, students' perceived satisfaction, and students' previous academic performance measures (high school grade point average (GPA) and Scholastic Aptitude Test (SAT) score). These factors have previously shown tendencies toward persistence in e-learning courses. Results of this study indicate that students' high school GPA was a significant predictor of e-learning course persistence for college student-athletes. 相似文献
ABSTRACT— This article describes the efforts of a small group of educators and researchers to build a model for making connections across mind, brain, and education. With a common goal of sharing, strengthening, and building useable knowledge about child and adolescent learning and development, we focused on questions of mutual interest to educators and researchers. We describe our efforts to develop a common vocabulary and language and to create opportunities for dialogue and discussion, including classes and talks for in-service and preservice teachers, research laboratories open to in-service and preservice teachers, local conferences that provided a context for educator and researcher interactions, and researcher outreach in the local education community at the administrative, classroom, and student levels. These activities represent concrete mechanisms by which links might be forged between educators and researchers within the context of Mind, Brain, and Education. 相似文献
The experiment reported here explored the importance of engaging 4-year-old children’s interest in the print itself during
storybook reading. We explored the effect of computer animation of the print in order to draw the child’s attention to each
word as it was read. We also investigated the influence of illustrating that not all visual displays are readable print on
the child’s print knowledge. The measures of interest were print concept knowledge and early reading skill. Results indicated
that simply drawing children’s attention to the print during shared reading was insufficient to facilitate children’s learning
of print conventions, but this attention to print while hearing stories read did improve children’s letter reading. The child’s
active engagement with the print during shared story reading led to further improvements in written language skills, as illustrated
by gains in knowledge about print concepts. 相似文献
Past studies have examined the contents of journal articles in school psychology, and more recently there has been increased interest in examining the frequency and characteristics of experimental studies appearing in school psychology journals. However, no prior studies have examined the international representation of experimental and intervention studies. This study evaluated every article published from 2002 to 2016 across eight school psychology journals that publish international scholarship. Several research questions were addressed (e.g., what is the frequency of experimental research internationally, what are the characteristics of those studies, and is the scholarship consistent with the global geography of school psychology?). Overall, findings revealed that although the field of school psychology is arguably international, the experimental research reflected in the eight journals selected for review does not adequately represent the global geography of the field, thereby also suggesting that the degree of internationalization in school psychology is relatively poor. The importance of these and related findings is discussed, and recommendations are provided that may help to improve the geographical representation of experimental research in school psychology as well as its overall internationalization. 相似文献
