Students' preferences for service delivery: pull-out, in-class, or integrated models     

J R Jenkins  A Heinen 《Exceptional children》1989,55(6):516-523

This study assessed students' preferences about where and by whom they receive instruction for learning difficulties. Subjects were 686 special, remedial, and regular education students in grades 2, 4, and 5, from classrooms that used a pull-out, in-class, or integrated model for specialized instruction. Results of student interviews indicated that children's preferences for in-class and pull-out services were affected by the service delivery model used in their classroom and their grade level. The majority of children preferred to receive additional help from their classroom teacher rather than from a specialist.  相似文献   

Some trends in distance education in Africa: An examination of the past and future role of distance education as a tool for national development     

Janet Jenkins 《Distance Education》1989,10(1):41-63

Distance education figures prominently among strategies recently proposed to assist African countries escape from educational crisis. Africa has already made considerable use of distance education to extend access to formal education, although most public institutions have often been severely constrained by lack of finance and manpower. Case studies of Zambia, Kenya and Zimbabwe suggest that critical factors for the effectiveness of distance education are the provision of adequate resources and firm political backing. It is probable that distance education will continue to be used to strengthen formal education by training primary teachers, extending access to secondary education and by providing tertiary education although, so far, few African countries have attempted degree level studies at a distance. In order for all these programmes to be effective, more resources must be forthcoming and integration of distance education with the formal system is desirable. Otherwise distance education may remain at the periphery, its potential under‐used.  相似文献   

Effects of tutoring in phonological and early reading skills on students at risk for reading disabilities     

Vadasy PF  Jenkins JR  Pool K 《Journal of learning disabilities》2000,33(6):579-590

This study examined the effectiveness of nonprofessional tutors in a phonologically based reading treatment similar to those in which successful reading outcomes have been demonstrated. Participants were 23 first graders at risk for learning disability who received intensive one-to-one tutoring from noncertified tutors for 30 minutes, 4 days a week, for one school year. Tutoring included instruction in phonological skills, letter-sound correspondence, explicit decoding, rime analysis, writing, spelling, and reading phonetically controlled text. At year end, tutored students significantly outperformed untutored control students on measures of reading, spelling, and decoding. Effect sizes ranged from .42 to 1.24. Treatment effects diminished at follow-up at the end of second grade, although tutored students continued to significantly outperform untutored students in decoding and spelling. Findings suggest that phonologically based reading instruction for first graders at risk for learning disability can be delivered by nonteacher tutors. Our discussion addresses the character of reading outcomes associated with tutoring, individual differences in response to treatment, and the infrastructure required for nonprofessional tutoring programs.  相似文献

String vibration dampers do not reduce racket frame vibration transfer to the forearm     

F-X Li  D Fewtrell  M Jenkins 《Journal of sports sciences》2013,31(11-12):1041-1052

In this study, we examined the effect of string vibration damping devices on reducing racket frame vibration transfer to the forearm. Twenty participants volunteered to hold a tennis racket stationary in a forehand and backhand stroking position while tennis balls were fired at 20 m?·?s^?1 towards two impact locations, the node of vibration and the dead spot. A three-way analysis of variance with repeated measures on damping condition, impact location and stroke condition was performed on the data. The resonant frequency of the hand-held racket was found to be ～120 Hz. No significant differences in amplitude of vibration at the resonant frequency were found for the wrist or the elbow when damped and non-damped impacts were compared. Impacts at the dead spot produced greater amplitudes of vibration (P <?0.01) but no interaction between impact location and string dampers was evident. The string dampers had no effect on the grip force used or the muscle electrical activity in the forearm after impact. In conclusion, we found that string dampers do not reduce the amount of racket frame vibration received at the forearm. We suggest that string dampers remain a popular accessory among tennis players because of their acoustic effects and psychological support rather than any mechanical advantage.  相似文献   

Identifying Science Understanding for Functional Scientific Literacy     

Edgar W. Jenkins 《Studies in Science Education》2013,49(1):1-25

Students' questions play an important role in meaningful learning and scientific inquiry. They are a potential resource for both teaching and learning science. Despite the capacity of students' questions for enhancing learning, much of this potential still remains untapped. The purpose of this paper, therefore, is to examine and review the existing research on students' questions and to explore ways of advancing future work into this area. The paper begins by highlighting the importance and role of students' questions from the perspectives of both the learner and the teacher. It then reviews the empirical research on students' questions, with a focus on four areas: (1) the nature and types of these questions; (2) the effects of teaching students questioning skills; (3) the relationship between students' questions and selected variables; and (4) teachers' responses to, and students' perceptions of, students' questions. Following this, some issues and implications of students' questions for classroom instruction are discussed. The paper concludes by suggesting several areas for future research that have significant value for student learning.  相似文献
