The purpose of this study was to determine parents’ and teachers’ perceptions of standards-based and traditional report cards. Participants included 115 parents/guardians of students from a single, midsize school district that had implemented a standards-based report card. During the first two marking periods, all parents/guardians received both a traditional report card in which teachers assigned a single overall grade for each subject and a standards-based report card that included marks for individual standards within subjects. After midyear, parents were asked to complete a survey that asked which form they preferred and the reasons for their preference. Three hundred and eighty three teachers from two nearby midsize school districts considering the adoption of the same standards-based report card completed a similar survey. Parents overwhelmingly preferred the standards-based form. The teachers considering the adoption of a standards based report card were positive overall, but significantly less than the parents who had received them.  相似文献

This response to Leah A. Bricker and Phillip Bell??s paper, GodMode is his video game name, examines their assertion that the social nexus of gaming practices is an important factor to consider for those looking to design STEM video games. I propose that we need to go beyond the investigation into which aspects of games play a role in learning, and move on to thinking about how these insights can actually inform game design practice.  相似文献

As part of educational reform, many institutions of higher education are undergoing accreditation processes. Based on interviews, observations, and the author's experiences in accreditation reviews, this discussion delineates three stages of planning for an accreditation process. Recommendations are organized by each stage of preparation into long- and short-term action plans with specific tasks. Analyzing the process of accreditation across institutions and programs led to the identification of common elements that can make planning an accreditation effective and efficient. This article maps the roles and responsibilities of accreditation stakeholders and the need for communication and collaboration throughout the process.Ann L. Wood earned a Ph.D. in educational psychology from The University of Michigan and a M.A. in special education and a B.A. in sociology, psychology, and education from Michigan State University. She is currently the Co-Principal Investigator for the Comprehensive Teacher Education Institute and an Assistant Professor in the Charter College of Education at California State University, Los Angeles. Her special interests are educational reform, urban education, lives of faculty and teachers, higher education, teacher development, and teacher induction  相似文献

In 1976, Head Start introduced a “Strategy for Spanish-Speaking Children.” The strategy provided support in four areas of activity, which included: (1) Basic and applied research on the developmental progress of Spanish-speaking children; (2) Regional Resource Centers intended to provide access to bilingual/bicultural materials and assistance in their implementation; (3) Head Start staff training; and (4) Curriculum model development in two languages, permitting individualized instruction in either language, and incorporating multicultural resources that facilitate cognitive and social growth.The most significant outcome of the strategy for the Spanish-speaking has been the curriculum development effort and its accompanying evaluation. The remainder of this paper will describe the curriculum development effort, th evaluation results, and some policy implications for national efforts in bilingual education.  相似文献

Constructing and experiencing boyhoods in research in London   总被引:1,自引:1,他引:1  
When Rob was about 14‐years‐old, at an all male boarding school, he was so glad that he did not have a tiny penis like another boy who was called girl. He was popular because he was good at sport, missed his mum and dog terribly but never showed it (except a little to his mum and dog) and talked a lot about girls he fancied. These memories were triggered by an interview based study on the identities of 11‐ to 14‐year‐old boys in London which we conducted from 1997–2000. Rob was the interviewer, and he interviewed boys in groups (45: 36 single sex and nine mixed) and individually (79) in 12 London schools.  相似文献

This research examined the hypothesis that a tendency to base one's self-worth on peer approval is associated with positive and negative aspects of children's well-being. A sample of 153 fourth through eighth graders (9.0 to 14.8 years) reported on need for approval, global self-worth, social-evaluative concerns, anxiety and depression, and exposure to victimization. Teachers reported on social behavior. Results confirmed that need for approval is a two-dimensional construct composed of positive (enhanced self-worth in the face of social approval) and negative (diminished self-worth in the face of social disapproval) approval-based self-appraisals. Need for approval had trade-offs for well-being that depended on the dimension (positive vs. negative), the psychological domain (emotional vs. social adjustment), children's sex and age, and children's social context (high vs. low peer victimization).  相似文献

This study investigated student perceptions of control, trust, and intimacy as dimensions of teacher‐student relationships, and. the correlation between these relational variables and reports of learning. Control, trust, and intimacy are viewed as core dimensions of interpersonal relationships, and it is hypothesized that students who engage in out of class communication have relationships that are more interpersonal in nature than students who do not engage in out of class communication with teachers. This hypothesis was supported. Additionally, students who perceived their teachers as exhibiting higher levels of shared control, trust, and intimacy reported greater learning.  相似文献

Extending previous investigations by Loeb of mobilities in gaseous mixtures using his procedure except that the auxiliary field in these measurements was made equal to the advancing field thus giving absolute values of the mobilities, measurements of mobilities were made in mixtures of CH3NO2H2 and CH3CNH2. The mobilities in H2 were 7.12 for the positive ions and 10.46 for the negative ions in cm./sec. per volt/cm. Those in CH3NO2 were 0.221 cm./sec. per volt/cm. for both ions and in CH3CN they were 0.234 cm./sec. per volt/cm. for both ions. Both ion mobilities deviated from Blanc's law in CH3NO2 indicating the formation of complexes with the CH3NO2 ions somewhat greater in size than the normal ions in H2. The molecules attached to negative ions somewhat less readily than to the positive ions but both final ions were of the same size. In CH3CN mixtures both positive and negative ions deviated from Blanc's law, the positive ion showing more ready attachment of CH3CN. The negative ion had consistently a higher mobility than the positive ion, a circumstance indicating a smaller ion and suggesting that the attaching molecule might not be CH3CN but some impurity. Both ion addition products in CH3CN are larger than the normal ion in H2 but smaller than those in CH3NO2 as was to be expected.  相似文献

Concept of word—the awareness of how words differ from nonwords or other linguistic properties—is important to learning to read Chinese because words in Chinese texts are not separated by space, and most characters can be productively compounded with other characters to form new words. The current study examined the effects of reader, word, and character attributes on Chinese children’s concept of word in text. A total of 164 fifth-grade Chinese children participated in this study. Concept of word was measured by children’s lexical decisions about words and nonwords embedded in strings of characters. Cross-classified multilevel logistic models showed that reader attributes, including reading comprehension, vocabulary knowledge, and morphological awareness, interacted with certain word or character attributes in predicting children’s lexical decisions about words or nonwords. This study sheds light on the complex relationships between reader, word, and character attributes in the formation of concept of word in Chinese.  相似文献
