In this study an abusive parent was instructed in techniques of behavior modification. It was hypothesized that the parent-child interactions would improve as the mother, Mrs. X, began modifying her daughter Jan's behavior.An A-B - A-B reversal design was implemented. Baseline data was collected to determine the frequency with which Jan interrupted Mrs. X. During the treatment phase, Mrs. X was to ignore Jan's interruptions and positively reinforce Jan when she spoke to Mrs. X without interrupting. However, Mrs. X did not apply the treatment consistently and the frequency of Jan's interruptions did not change significantly. Thus a return to baseline and reimplementation of the treatment was not necessary.In order to ascertain whether the parent-child interactions chanqed, two thirty-minute tapes of the baseline sessions were made and two thirty-minute tapes of the treatment sessions were made. The tapes were transcribed and assessed according to the Kasprin-Burrelli, Egolf, and Shames Parent-Child Interaction Scale (Kasprin-Burrelli, et al., 1972).The quality of the parent-child interactions, as measured by the Kasprin-Burrelli, et al., Parent-Child Interaction Scale, improved throughout the study. Thus, it is impossible to state that the treatment was responsible for the improvement. It is hypothesized that the presence of the examiner resulted in the improvement. Mrs. X is a college-educated woman and appears to need adult stimulation. When Mrs. X's need for adult stimulation was met, then her interactions with Jan improved. Thus, although Mrs. X did not modify Jan's interruption behavior, her interactions with Jan did improve throughout the experiment. 相似文献

This paper reports on a study involving the identification and measurement of collaboration in an online asynchronous discussion (OAD). A conceptual framework served for the development of a model which conceptualises collaboration on a continuum of processes that move from social presence to production of an artefact. From this model, a preliminary instrument with six processes was developed. Through application of the instrument to an OAD, the instrument was further developed with indicators added for each process. Use of the instrument to analyse an OAD showed that it is effective for gaining insight into collaborative processes in which discussants in an OAD do or do not engage. Use of the instrument in other contexts would test and potentially strengthen its reliability and provide further insight into the collaborative processes in which individuals engage in OADs. Analysis of an OAD using the instrument revealed that participants engaged primarily in processes related to social presence and articulating individual perspectives, and did not reach a stage of sharing goals and producing shared artefacts. The results suggest that the higher‐level processes related to collaboration in an OAD may need to be more explicitly and effectively promoted in order to counteract a tendency on the part of participants to remain at the level of individual rather than group or collaborative effort. 相似文献

The role of play in young children's learning has always been considered to be of primary importance. Thus, early childhood programs have been characterized by curricula that provide plenty of opportunity for young children to play and interact with materials, ideas, and people. As we approach the new millennium, the impact of the new information technologies on play and as play, for young children need to be conceptualized and discussed. This article begins that discussion. The view that there are opportunities for young children to play in technological environments as well as with traditional materials and contexts is presented. 相似文献

Numerous studies suggest an association between language and executive function (EF), but evidence of a developmental relationship remains inconclusive. Data were collected from 75 deaf/hard-of-hearing (DHH) children and 82 hearing age-matched controls. Children were 6–11 years old at first time of testing and completed a battery of nonverbal EF tasks and a test of expressive vocabulary. These tasks were completed again 2 years later. Both groups improved their scores on all tasks over this period. DHH children performed significantly less well than hearing peers on some EF tasks and the vocabulary test at both time points. Cross-lagged panel models showed that vocabulary at Time 1 predicted change in EF scores for both DHH and hearing children but not the reverse. 相似文献

Research and public policy on academic entrepreneurship are largely based on the assumption that faculty members start businesses to commercialize inventions that have been disclosed to university administrators and have been patented. In this paper, we analyze a sample of 11,572 professors and find that much academic entrepreneurship occurs outside the university intellectual property system. Specifically, about 2/3 of businesses started by academics are not based on disclosed and patented inventions. Moreover, we show that individual characteristics, departmental and organizational affiliations, and time allocation of academics that have started business outside the IP system are different from those of academics that have started businesses to exploit disclosed and patented inventions. We discuss the implications for research on and the practice of academic entrepreneurship. 相似文献

The purpose of this study was to explore the influence of the four traditionally hypothesized sources of self-efficacy on learners' self-efficacy beliefs regarding learning mathematics in an asynchronous environment. The context of the study was a college algebra and trigonometry course offered in an asynchronous, technology-intensive emporium model at a large, public university in the southeastern United States. Participants (N = 99) completed surveys assessing their self-efficacy to learn mathematics in this environment as well as to assess their mastery experiences, vicarious experiences, social persuasion, and physiological state. Regression analysis indicated that in this environment, the most important factors are vicarious experiences, followed by affective/physiological influences. 相似文献

The influence of parenting skills on adolescent outcomes among children affected by maternal HIV/AIDS (N = 118, M age = 13) was investigated. Among families with more frequent family routines, over time adolescents showed lower rates of aggression, anxiety, worry, depression, conduct disorder, binge drinking, and increased self‐concept. Among families with higher levels of parental monitoring, adolescents showed significant declines in anxiety and depression, conduct disorder, and binge drinking, along with increased self‐concept. Mothers’ level of illness was associated with parenting. Greater variability in parental monitoring resulted in higher levels of problem behaviors. 相似文献

This paper introduces a set of services for the creation of on-line surveys, questionnaires, exams and self-assessment tests within a virtual community system used in e-learning settings. The system, called "Online Communities", is a dynamic web application used as platform for blended learning activities by the Faculty of Economics of the University of Trento. The functionalities added to the platform are contextualized into virtual communities, where activities take place. This allows us to create, submit and analyze questionnaires within and/or outside the boundaries of a community. Furthermore, the system allows to manage libraries of queries organized by the teacher/administrator of the community according to topics and levels of difficulty, in order to produce tests and generate self-assessment sessions on behalf of students. The addition of a questionnaire/ poll/self-assessment tool to a virtual community system can add a lot of interesting features, mainly using the inheritance mechanism implemented among different hierarchically-connected communities. This paper will present these functionalities and highlight one of these services, precisely the one dedicated to self-assessment. In the system, self-assessment tests have indeed a double nature: (1) They are useful to students for checking their own level of preparation; and (2) They are useful to lecturers as an indicator of the level of preparation reached by the students. In order to encourage the use of the system within the whole educational process, and not to limit the real use of the service to the period of the final exams only, the possibility has been foreseen for each participant to share his/her own test results, comparing them with the other members of the community, and even offering real "challenges", thus transforming passive and "solitary" learning into something much more stimulating and "social". 相似文献
