At a time when the public sector and state education (in the United Kingdom) is under threat from the encroaching marketisation policy and private finance initiatives, our research reveals white middle‐class parents who in spite of having the financial opportunity to turn their backs on the state system are choosing to assert their commitment to the urban state‐run comprehensive school. Our analysis examines the processes of ‘thinking and acting otherwise’, and demonstrates the nature of the commitment the parents make to the local comprehensive school. However, it also shows the parents’ perceptions of the risk involved and their anxieties that these give rise to. The middle‐class parents are thus caught in a web of moral ambiguity, dilemmas and ambivalence, trying to perform ‘the good/ethical self’ while ensuring the ‘best’ for their children.  相似文献

Case histories were compiled of 100 instances of technological change in 102 manufacturing companies in eight industries in Ireland, Spain and Mexico. The cases are analyzed for the source of initial ideas and for sources of technology employed in resolving major problems.Technology is found to flow principally through informal channels within industries. Very little information was obtained from the formal mechanisms or institutions normally considered central to the technology transfer process.Foreign subsidiaries obtain the greatest proportion of their technology from their parent firms. Surprisingly, they are found to have several channels of technology blocked to them, which are more readily available to domestic firms. Domestic firms, in many ways have easier access to foreign technology than do the subsidiaries of multinational firms.Product and process innovations originate in somewhat different quarters. Process innovations are slightly more likely to be based on foreign technology; product innovations are more likely to be based on domestic technology.The results reported in the present paper are very similar in many ways to results reported previously in Brazil and Australia.  相似文献

Five experiments are reported in which rats were given CS-shock pairings and then permitted, in the absence of shock, to perform a hurdle-jump response that led to CS offset. In Experiment 1–4, the animals failed to learn the required response. Although several procedural variations were employed, the experimental groups continued to perform no better than backward-conditioned controls. In Experiment 5, some animals were punished for remaining immobile during a single trial at the start of hurdle-jump training. These animals performed significantly better than nonpunished controls and better than any group in Experiments 1–4. The results support the idea that the major role of the CS in escape-from-fear situations is to activate an innate motivational system which chooses between the species-specific defense reactions of freezing and fleeing.  相似文献

Academic socialization by low‐income immigrant mothers from Mainland China was investigated in two studies. Immigrant Chinese mothers of first graders (= 52; Mage = 38.69) in the United States (Study 1) and kindergartners (= 86; Mage = 36.81) in Hong Kong (Study 2) tell stories that emphasized achieving the best grade through effort more than did African American (= 39; Mage = 31.44) and native Hong Kong (= 76; Mage = 36.64) mothers, respectively. The emphasis on achievement was associated with mothers' heightened discussion on discrimination (Study 1) and beliefs that education promotes upward mobility (Study 2), as well as children's expectations that a story protagonist would receive maternal criticism for being nonpersistent in learning (Study 2).  相似文献

In the spring of 1990, theTeenage Mutant Ninja Turtles (TMNT) movie was released to the biggest grossing box office sales of a spring release movie in history. The movie followed on the heels of more than a year of the TMNT television cartoon and its accompanying line of toys. After the movie's release, interest in the Turtles was kept high by the daily dose of the TV cartoon, TMNT home videos, video games, and the presence of more than 1,000 toys and other products marketed with the TMNT logo. And then, a year after the first movie, on March 22, 1991, the sequel,TMNT II: The Secret of the Ooze, opened at cinemas around the country.Nancy Carlsson-Paige is Associate Professor of Education, Lesley College Graduate School, Cambridge, MA.

It is possible to distinguish between structural and integral forms of curriculum provision for highly able students. Both these forms offer advantages and disadvantages, while there are also particular problems associated with enrichment. Three common forms of differentiation under the integral umbrella are by inputs, by outputs, or by developmental differentiation. Of these, developmental differentiation is the most appropriate. Its theoretical context can be matched to the needs which able students are reported to have. Translated into a practical methodology for use in schools and colleges, six types of cognitive process pedagogies which provide the appropriate curriculum enrichment can be identified: Games and simulation, cognitive study skills, real problem solving and investigative learning, collaborative learning, experiential learning and language experience methods. These facilitate the development of higher order cognitive and metacognitive skills and offer challenge in all content areas.  相似文献

This study used a within-subjects design to explore two instructional conditions for developing vocabulary in second-grade Spanish-speaking English learners (ELs)—extended instruction and embedded instruction implemented during shared interactive reading. Words assigned to the extended condition were directly taught using a multifaceted approach that included visuals, bilingual definitions, examples, spelling, and partner-talk about the words’ meaning. Words assigned to the embedded condition were taught solely through brief definitions to embedded text, writing activities, and songs. In the control condition students heard the target words read aloud during shared interactive reading but without definitions or direct instruction. The study also explored the interaction between instructional condition and word type. Four types of words—abstract cognates, abstract noncognates, concrete cognates, and concrete noncognates—were randomly assigned to each condition. Nine teachers in four schools and 187 second-grade ELs participated in this within-subjects intervention, which took place in transitional bilingual classrooms. Findings indicated that across all word types, both extended and embedded instruction were more effective than the control condition in helping ELs acquire vocabulary. Findings also indicated that extended instruction was more effective then embedded instruction for all word types except concrete cognates suggesting that these young Spanish-speaking ELs were advantaged by word knowledge in their home language. Finally, while embedded instruction was less effective than extended instruction, it was much more effective than a control condition. Embedded instruction takes significantly less preparation and instructional time than extended instruction, offering teachers a practical way to teach more vocabulary to ELs.  相似文献

Many studies have reported an increase in mental health problems during post-secondary transition, often originating from high school years. The present study examined how depressive symptoms during the 2 years following the post-secondary transition could be predicted by, on the one hand, school performance, externalized and learning difficulties, and depressive symptoms before the post-secondary transition, and on the other hand, personal factors, family functioning, and adjustment to college after the transition. From a sample of 438 participants (M = 16.20, SD = 0.87) at time point 1, an integrated model was elaborated using structural equation modeling. The statistical analyses showed that the five constructs fit the data well. The path coefficients showed a negative relationship between externalized and learning problems as perceived by the teacher (ELPT) before the transition and academic performance (AP). Personal characteristics (PC) negatively predicted academic adjustment (AC) over time, whereas the path coefficients between the family factor (FF) and AC were not significant over time. ELPT and AP negatively predicted depression at time point 1. At time points 2 and 3, PC positively predicted depression, and depressive symptoms were positively related over time. The percentage of variance accounted for by the depressive symptoms increased over time.  相似文献
