A professional development program for 18 teachers was conducted over a two-year period. The participating teachers taught
in intermediate schools (students aged 11–13) and secondary schools. The teachers worked collaboratively to improve their
mathematics teaching, with encouragement to reflect on their practice but with minimal instruction from the researchers. Results,
as defined by change in teaching practices, beliefs, and reflections, and student achievement, indicated that the collaborative
program was particularly useful for experienced secondary school teachers but less useful for intermediate school teachers.
We concluded that this type of professional development was most useful for teachers who had sufficient knowledge of mathematics;
these teachers were able to focus on pedagogy and to draw connections between aspects of the mathematics they taught, without
recourse to a specialist's advice.

In this article we report a longitudinal extension of previous findings about the critical role of temperamental inhibitory or effortful control as the contributor to developing conscience in young children. A comprehensive observational battery, highly internally consistent, was developed to measure inhibitory control in 83 children at early school age who had been followed since toddlerhood and had been assessed using similar batteries at toddler and preschool age. We again confirmed the findings of robust longitudinal stability of inhibitory or effortful control, now from toddler to early school age, the increase with age, and gender differences, with girls outperforming boys. We also reaffirmed strong links, both contemporaneous and in the longitudinal sense, between in hibitory control and multiple, diverse measures of children's conscience at early school age, including observations of moral conduct, moral cognition, and moral self. The findings are discussed in view of the increasingly appreciated importance of temperament for critical aspects of socialization. 相似文献
The first part of the article provides a historical account of the broad phases of development that educational television has passed through as a result of social and technological influences:
its beginnings in broadcasting in the fifties and sixties;
its development through the video age in the seventies and eighties, with widening scope and opportunity as a result of developments in production and reception/recording equipment and an expansion of communication channels;
its present potential, at the dawn of the interactive age, as a result of the influences of new technology.
The article then examines the problems of integrating new television‐related technologies into the educational system and draws attention to:
the frequent past failures of the educational system to fully exploit new technologies, resulting in superficial integration and ineffectual use;
the current tensions between the traditional educational technology approach and the drives behind much new technology;
the need for appropriate systems and structures to ensure that the evaluation of such new technologies is properly resourced and effectively carried out.
Multiple shifts in reward amount were given to rats in a straight runway. Both positive and negative contrast effects were observed. A positive contrast effect was observed, however, only if the shift from small to large reward occurred while the subject was evidencing a negative contrast effect. Implications for current conceptions of reinforcement contrast are discussed. 相似文献

This article analyses data from over 1000 student questionnaires dealing with how students currently use the web to support their learning. It discusses student understanding, needs, and expectations of the web and the overwhelming perception that the web now forms an integral part of their study and research practices. However, these practices require greater definition and refinement for and by the student. Evidence from some teaching staff is compared with that from students for validation purposes and has also revealed striking differences in perception and attitudes between the two groups. We identify specific needs on the part of most students in our survey who require greater guidance and study skills when using the web. These “Netskills” are described and recommendations are made concerning their acquisition and future development by students who are demanding that such skills become part of their own learning strategies. 相似文献
OBJECTIVE: This study examines the unique contribution of five types of maltreatment (sexual abuse, physical abuse, emotional abuse, physical neglect, emotional neglect) to adult health behaviors as well as the additive impact of exposure to different types of childhood maltreatment. METHOD: Two hundred and twenty-one women recruited from a VA primary care clinic completed questionnaires assessing exposure to childhood trauma and adult health behaviors. Regression models were used to test the relationship between childhood maltreatment and adult health behaviors. RESULTS: Sexual and physical abuse appear to predict a number of adverse outcomes; when other types of maltreatment are controlled, however, sexual abuse and physical abuse do not predict as many poor outcomes. In addition, sexual, physical, and emotional abuse and emotional neglect in childhood were all related to different adult health behaviors. The more types of childhood maltreatment participants were exposed to the more likely they were to have problems with substance use and risky sexual behaviors in adulthood. IMPLICATIONS: The results indicate that it is important to assess a broad maltreatment history rather than trying to relate specific types of abuse to particular adverse health behaviors or health outcomes. 相似文献
The aim of the study is to demonstrate, via the use of the discipline of Education, a procedure to identify and weight the importance of various indicators of research productivity which in turn have become significant components in determining quality within and between universities. The methodology allows for the identification of indicators that are most important, and ascertains if there are differences among academics as to the relative weighting of the various research indicators.Highly valued indicators of research productivity amongst the Education academics were refereed journal articles, peer reviewed books, and major competitive research grants. Refereeing was critical in the determination of quality in research productivity, and the findings generalized across many academics regardless of their own personal productivity. It is recommended that the methodology can serve to determine the tacit weights that academics within and across disciplines attach to various research products. At least, this method makes academics and administrators aware of the weightings they are actually using when making decisions about the quality of academic departments. 相似文献
Conclusion Identify standards, align curricula, support technology—these are the three strategies that bring clarity to the process.
As technology changes, the standards, curricula and support must change. ACTIVStudio, interactive whiteboards and cyber diaries
are not just buzzwords — they are the new language of technology. The Citadel School of Education is paying attention — making
sense of the challenge of keeping current technology in educational leadership programs.
