Connectedness among taiwanese middle school students: a validation study of the hemingway measure of adolescent connectedness     

Michael?J.?KarcherEmail author  Yun?Lee 《Asia Pacific Education Review》2002,3(1):92-114

Theories of adolescent connectedness suggest that adolescents strive to become connected by engaging with and valuing the people, activities, and worlds in their social ecology. The purpose of this study was to examine the psychometric properties of a measure designed to assess these worlds of connectedness among 320 junior high school students in Taiwan. The subscales and composite scales evidenced satisfactory reliability and concurrent validity. A hypothesized three-factor, higher order structural model of connectedness was cross-validated. Girls were generally more connected than boys. Both connectedness to school and to friends explained more variance in connectedness to self than did family connectedness. There was mixed support for separation-individuation processes. The measure appears promising in terms of future research on adolescent social development in the Asia Pacific.  相似文献   

The Effect Teaching Experience Has on Perceived Effectiveness of Interactive Television as a Distance Education Model for Elementary School Science Teacher’s Professional Development: Another Digital Divide?     

Leonard?A.?AnnettaEmail author  James?Minogue 《Journal of Science Education and Technology》2004,13(4):485-494

The first year of a 5 year professional development project for elementary teachers in two mid-western states integrated a bridge of two distinctly different distance education networks (T-1 and fiber optics) to provide science professional development for elementary school teachers in rural communities. Interactive television (ITV), the title given to the distance component, consisted of a series of twenty-four, 2 h presentations by scientists and content specialists. It provided expansion to the science pedagogical content knowledge of the elementary teachers involved. Eighty-five teachers in 38 school districts from the two states completed individual surveys following the final ITV session. Analysis of variance of participants post-session survey scores yielded differences (p < 0.05) on the subscales measuring perceived effectiveness of using distance education for professional development purposes and years of teaching experience. Teachers with over 20 years of classroom experience perceived the use of distance education technologies for science professional development to be more effective than teachers with 16–20 years of classroom experience. These results might suggest another digital divide.  相似文献

Fiber optic biosensor of immobilized firefly luciferase     

蔡谨  孟文芳  吉鑫松 《浙江大学学报(A卷英文版)》2002,3(5):563-566

Luciferase from firefly lantern extract was immobilized on CNBr-activated Sepharose 4B. The kinetic properties of immobilized luciferase were extensively studied. TheK _m′ for D-luciferin is 11.9 μmol/L, the optimum pH and temperature for Sepharose-bound enzyme were 7.8 and 25°C respectively. A luminescence fiber optic biosensor, making use of immobilized crude luciferase, was developed for assay of ATP. The peak light intensity was linear with respect to ATP concentration in range of 10⁻⁹–10⁻⁵ mol/L. A biological application was also demonstrated with the determination of serum ATP from rats bred in low versus normal oxygen environments.  相似文献   

Improving the compositions of students with learning disabilities using a strategy involving product and process goal setting.     

S Graham  C MacArthur  S Schwartz  V Page-Voth 《Exceptional children》1992,58(4):322-334

This study was conducted to determine if a planning and writing strategy would improve the essay writing of students with learning disabilities. Four participants were taught a strategy designed to facilitate the setting of product and process goals, generation and organization of notes, continued planning during writing, and evaluation of goal attainment. Training effects were investigated using a multiple probe design across subjects. Strategy instruction had a positive effect on students' essay writing performance and knowledge of the writing process, and effects were maintained over time.  相似文献

A Comparative Sociology of School Knowledge     

John Shepherd  Graham Vulliamy 《British Journal of Sociology of Education》1983,4(1):3-18

Despite a recently renewed theoretical interest in both North America and in Britain in the sociology of school knowledge, we still have little, if any, comparative empirical material from these two continents. This paper reports the findings of a sociological study, designed to replicate the previous English empirical work by Vulliamy, into music teaching in Ontario high schools. Unlike in England, no overt culture clash was found in Ontario schools between ‘school’ music and ‘students’ ‘ music, both because of the wider scope of ‘what counts as school music’ in Canada and because music is not a compulsory school subject there. However, by focusing upon the deep structure of the pedagogical process, as opposed to surface features of classroom interaction, it is argued that particular ideologies of the dominant musical culture are transmitted in very similar ways in both contexts. What is shared is a conception of music as equatable with musical notation. The ideological significance of this is pinpointed in an analysis of the structurally homological relationship between different musical languages and the social/‐cultural contexts of their creation. The processes of school music teaching not only contribute to the legitimation of a dominant musical ideology, but also to much more pervasive ideological assumptions underpinning capitalist societies.  相似文献

Introduction to this Special Issue     

Lina?KashyapEmail author 《International journal for the advancement of counseling》2004,26(4):337-339

In 2001, for the first time in the history of the International Association for Counselling, International Conference was held in a developing Asian country–India, with the theme Families in Transition–Counselling in Transition–Meeting the Challenges Ahead. This special issue contains some of the presentations made by Indian participants during this conference which best reflect the challenges and diversities of counseling efforts with families in India. The first article was specially written for this issue in order to give an international relationship of this journal an in depth contextual understanding of Indian families in transition and the challenges they pose to the contemporary Indian counselor. Two articles are reflected to counseling families affected by socio-politial and economic changes. Five authors have written on counseling related to physical and mental disability/addiction and last two articles are reflected to authors experiences as family counselors.  相似文献
