Facilitating small-group learning: A comparison of student and staff tutors' behavior     

Jos H. C. Moust  Henk G. Schmidt 《Instructional Science》1994,22(4):287-301

This study focused on students' observations of student and staff tutors' behavior during two academic courses, using a thirtynine-item rating scale. The study took place within an integrated problem-based law curriculum. Six major factors in tutors' behavior were identified. Differences between student and staff tutors' performance were investigated. The results showed that student tutors were better at understanding the nature of the problems students face in attempting to master the subject-matter. Student tutors were also more interested in students' daily lives, study experiences and personalities. In addition, student tutors referred to end-of-course examinations more frequently than staff tutors to direct student learning. Alternatively, staff tutors used their subject-matter expertise more often and displayed more authoritarian behavior than student tutors. No differences were found with respect to tutors' focus on cooperation among group members. The results are interpreted in terms of the nature of the knowledge and experiences of students and staff with regard to problem-based learning and its requirements.  相似文献

Developmental arrest at the logographic stage: impaired literacy functions in Klinefelter's XXXY syndrome     

Philip H.K. Seymour  Henryka M. Evans 《Journal of Research in Reading》1988,11(2):133-151

We report an analysis of reading and spelling processes in a case of developmental disability associated with a genetic anomaly (Klinefelter XXXY syndrome). The results are interpreted within the framework of a model of reading and spelling development (Frith, 1985). An almost complete absence of alphabetic functions was noted. Reading appeared to be based on a ‘logographic lexicon’ (Seymour & Elder, 1986), and spelling on a letter sequence generator which was modifiable by access to a limited store of word images.  相似文献   

One-to-One Computing and Student Achievement in Ohio High Schools     

Nancy L. Williams  Karen H. Larwin 《Journal of Research on Technology in Education》2016,48(3):143-158

This study explores the impact of one-to-one computing on student achievement in Ohio high schools as measured by performance on the Ohio Graduation Test (OGT). The sample included 24 treatment schools that were individually paired with a similar control school. An interrupted time series methodology was deployed to examine OGT data over a period of 5 to 8 years. Overall student performance and content-specific achievement in math, reading, science, social studies, and writing were not significantly affected by the introduction of 1:1 computing. Treatment schools using a netbook device produced the greatest overall change in scores.  相似文献   

Acculturation, substance use, and deviant behavior: examining separation and family conflict as mediators     

McQueen A  Getz JG  Bray JH 《Child development》2003,74(6):1737-1750

This longitudinal study examined how separation and family conflict mediated the effects of two acculturation variables (English language use and generational status) on substance use (alcohol, tobacco, and marijuana use) and deviant behavior outcomes in a Mexican American high school age sample. Structural equation modeling indicated that separation was a significant mediator of the relationship between acculturation and alcohol use, tobacco use, and deviant behavior. Family conflict mediated the effects of acculturation on marijuana use and deviant behavior. Model comparisons across gender groups suggested that generational status was an influential acculturation measure for females but not males. Additionally, English language use maintained a direct effect on marijuana use among females, whereas this relationship was mediated by separation for males.  相似文献   

Conflict, Social Competence, and Gender: Maternal and Peer Contexts     

Martha Putallaz  Laura Hellstern  Blair H. Sheppard  Christina L. Grimes  Kimberly A. Glodis 《Early education and development》1995,6(4):433-447

The current study was designed to address two major purposes. The first goal was to investigate the joint influence of children's sociometric status and sex on their conflict behavior, and the second goal was to explore the similarities and differences in children's conflict behavior across two contexts, specifically conflicts arising during interactions with mothers and with peers. Forty-two first-graders were videotaped playing with their mothers and then with an unfamiliar peer partner. Conflict behavior occurring in the mother-child context was quite different from that occurring between children, reflecting the contrast between the vertical and horizontal nature of these relationships. Most striking were the large number of sociometric status and sex differences in conflict behavior found across both contexts. Further, it appears that effective conflict behavior may differ for boys and girls. Implications for future research are discussed.  相似文献

Synthesis of RC transfer immittance functions with a minimum number of capacitors     

H.C. Reddy  C.P. Reddy  M.N.S. Swamy  V. Ramachandran 《Journal of The Franklin Institute》1982,313(4):197-206

In this paper a method for the realization of RC transfer immittance functions with an unsymmetrical lattice is presented. The method yields minimal capacitor realizations for Z₁₂(s) with no pole at s = 0 and ?y₁₂(s) having no pole at s = ∞. The number of resistors needed are only two more than the minimum needed.  相似文献
