This paper examines the polarization model from qualitative research in both Great Britain and the US, which claims that educational stratification practices polarize students into pro- and anti-school orientations. Because few researchers have adequately conceptualized school attitudes and behavior, social bonding theory (Hirschi, 1969) is used to provide a framework for examining the polarization hypothesis. Relying on High School and Beyond data from the US, an attempt is made to develop measures of respondents’ social bonding to school, including college expectations, absenteeism, disciplinary problems, and engagement. The polarization hypothesis is supported by these US data when examining educational stratification effects on the school bonding measures. Compared to academic-track students, general- and vocational-track students have Iowa college expectations, more disciplinary problems, and are less academically engaged, controlling for prior school orientations and for selection bias due to dropping out of school. For absenteeism, the general track has a significant positive effect, while vocational-track students do not differ from those in the academic track. In addition, students in the nonacademic tracks are more likely to drop out of school between the 10th and 12th grades compared to academic-track students. 相似文献

Despite the ubiquity of the term “inquiry” in science education literature, little is known about how teachers conceptualize inquiry, how these conceptions are formed and reinforced, how they relate to work done by scientists, and if these ideas about inquiry are translated into classroom practice. This is a multicase study in which 14 preservice secondary science teachers developed their own empirical investigations—from formulating questions to defending results in front of peers. Findings indicate that participants shared a tacit framework of what it means to “do science” which shaped their investigations and influenced reflections on their inquiries. Some facets of the participants' shared model were congruent with authentic inquiry; however, the most consistent assumptions were misrepresentations of fundamental aspects of science: for example, that a hypothesis functions as a guess about an outcome, but is not necessarily part of a larger explanatory system; that background knowledge may be used to provide ideas about what to study, but this knowledge is not in the form of a theory or other model; and that theory is an optional tool one might use at the end of a study to help explain results. These ideas appear consistent with a “folk theory” of doing science that is promoted subtly, but pervasively, in textbooks, through the media, and by members of the science education community themselves. Finally, although all participants held degrees in science, the participants who eventually used inquiry in their own classrooms were those who had significant research experiences in careers or postsecondary study and greater science‐content background. © 2004 Wiley Periodicals, Inc.

To provide timely and effective supports for students reading below grade level, schools require methods for quickly and accurately identifying those students in need. One method for identifying those students is through universal screening. Assessments such as oral reading fluency (ORF) and Maze reading comprehension are commonly used as screening assessments in middle grades. The current study examined ORF and Maze for evidence of bias across two subgroups known to be at increased risk for failure in reading: (a) students with learning disabilities and (b) students from low‐income households. Data from 4,215 students in the sixth (n = 1,126), seventh (n = 1,361), and eighth grades (n = 1,728) were analyzed. Results indicate no significant differences in predictive validity for students from low‐income households compared to students from middle and upper income households. For students with learning disabilities only 8th grade scores showed any evidence of bias compared to students without diagnosed disabilities. Implications and recommendations for future research are discussed. 相似文献

Basic science courses are extremely important as a foundation for scaffolding knowledge and then applying it in future courses, clinical situations as well as in a professional career. Anatomical sciences, which include tooth morphology, oral histology, oral embryology, and head and neck anatomy form a core part of the preclinical courses in dental technology programs. In this article, the importance and relevance of anatomical sciences to dental personnel with no direct contact with patients (dental technicians) and limited discipline related contact with patients (dental prosthetists) is highlighted. Some light is shed on the role of anatomical sciences in the pedagogical framework and its significance in the educational process and interprofessional learning of dental technicians and prosthetists using oral biology as an example in the dental curriculum. To conclude, anatomical sciences allow dental technicians and prosthetists to a gain a better insight of how tissues function, leading to a better understanding of diagnosis, comprehensive treatment planning and referrals if needed. Patient communication and satisfaction also increases as a result of this deep understanding of oral tissues. Anatomical sciences bridge the gap between basic science, preclinical, and clinical courses, which leads to a holistic approach in patient management. Finally, treatment outcomes are positively affected due to the appreciation of the macro and micro structure of oral tissues.

Time Use and Mathematics Achievement among American, Chinese, and Japanese High School Students 总被引:3,自引:1,他引:3
Cultural differences in the structure of adolescents' daily lives were examined by interviewing representative samples of 578 grade 11 students, aged 16–17 years, in Minneapolis, Taipei (Taiwan), and Sendai (Japan) about the amounts of time they spent in a wide variety of activities. Studying, interacting with peers, and watching television were the most frequent activities in all 3 locations, but the relative importance of each activity differed among the locations. Chinese students spent significantly more time than American students engaged in academic endeavors, such as attending school and after-school classes and studying. Japanese students did not spend significantly more time studying or attending after-school classes than American students, but they did spend more time attending school. American students, in turn, spent more time working and socializing with friends. Differences in adolescents' use of time were related to both cross-cultural and individual differences in mathematics achievement. 相似文献

Assessment plays an important role in first-year students’ transition to university, influencing how they learn. Poorly designed assessment can be demotivating and may even cause students to withdraw from university. An early low-stakes assessment task is recommended in first year, to provide information to students and staff on student progress, provide students with a positive experience and help them prepare for future assessments. This paper reports on first-year students’ experiences of two different early assessment tasks for two disciplines, one using an online quiz and the other a ‘research challenge’ that served as a precursor to writing an essay. The paper also presents lecturers’ reflections on what they learned, what they would change and the implications for others planning early assessment tasks for first years. Finally, ideas for future research are provided. 相似文献

Four experiments examined whether or not spontaneous recovery could occur after extinction in the conditioned taste-aversion paradigm. After three extinction trials, spontaneous recovery was obtained over an 18-day retention interval (Experiments 1, 2, and 3). The effect was not due to changes in the unconditioned preference for saccharin over the retention interval (Experiment 2) or to an increase in a nonextinguished aversion over time, as indicated by tests with both the original, nonextinguished aversion (Experiment 1) and with a weaker one (Experiment 3). Spontaneous recovery was not obtained when extinction was overtrained (eight trials) and a 49-day retention interval was used (Experiment 4). However, saccharin intake at asymptote reached the level of baseline water intake, and not the highly preferred level shown by never-conditioned controls. Results of all four experiments suggest that extinction does not return an averted taste to the status of an unconditioned one. 相似文献

The purpose of the study was to determine whether the field experience component of an undergraduate science methods course influenced teachers' concerns and attitudes toward science and science teaching. Age, grade-point average, openmindedness, and school assignment were examined as factors which might explain some of the variance in the dependent measures. A one-group pretest-posttest design was used. Students were administered the Teacher Concerns Questionnaire, the Science Teaching Attitude Scales, and the Rokeach Dogmatism Scale approximately eight weeks after the pretest. Results indicated that field experiences did not significantly change student concerns about teaching science but significantly improved student attitudes toward science and science teaching. Students differing in age, grade-point average, and openmindedness did not difer significantly in changes in concerns and changes in attitude toward science and science teaching. Students assigned to different schools differed significantly in changes in attitude toward science. 相似文献

First and fifth graders in Beijing and Chicago were given a battery of mathematics test. Whether tested with problems requiring solely computation or with ones requiring application of knowledge about mathematics, American children's performance was consistently inferior to that of Chinese children. Interviews with American children suggested that they like mathematics, believe they are doing well in mathematics, and do not perceive mathematics as a difficult subject. American children's poor performance appears to be attributable, in part, to low motivation for devoting more attention to mathematics. Low standards held by American parents for academic achievement and lower interest in teaching mathematics by American teachers appear to contribute to American children's poor performance. 相似文献

Private supplementary tutoring has long existed in Bangladesh, as elsewhere in the world, but in recent decades has become much more visible. Much tutoring “shadows” or reproduces formal schooling as fee-based academic teaching outside school hours. This paper focuses on school factors that shape demand for private supplementary tutoring in English at the secondary level, drawing on data gained from both quantitative and qualitative methods. The paper is especially concerned with urban and rural variations, noting that rates of tutoring are greater in urban areas but that many factors converge to create similarities. Private tutoring in English is highly demanded because English is a compulsory course; and in addition to being a subject in its own right, it assists in the learning of other subjects. While private tutoring may support the academic learning of some pupils, it also has problematic dimensions. As such, the spread of tutoring across urban and rural areas is not necessarily to be welcomed. 相似文献
