The concepts of randomness and variation are pervasive in science. The purpose of this study was to document how post-secondary life science students explain randomness and variation, infer relationships between their explanations, and ability to describe and identify appropriate and inappropriate variation, and determine if students can identify sources of variation. An instrument designed to test statistical concepts was administered to 282 college students from three universities, ranging from introductory non-science majors to science graduate students. Students readily distinguished between causes of variation. A naïve no-pattern concept of randomness persisted from first-year non-science majors to senior-level science majors, contributing to incorrect responses on the variation instrument. Students’ expressions of randomness were better predictors of performance on the variation instrument than their expressions of variation. It is argued that inclusion of everyday language uses of randomness in instruction can bridge the gap between vernacular and scientific uses of this term.  相似文献   

Towards another kind of borderlessness: online students with disabilities     

Yasuhiro Kotera  Vicky Cockerill  Pauline Green  Lucy Hutchinson  Paula Shaw  Nicholas Bowskill 《Distance Education》2019,40(2):170-186

Online learning is crucial to success for higher education institutions. Whilst the existing literature predominantly focused on its economic advantages, we focused on its inclusivity. At an online learning unit of a UK university, the number of students with disabilities (SWD) is three times higher than the national average. Having a degree makes significant financial and psychological differences in the lives of SWD. Though recent literature focused on inclusivity of online learning, an appraisal of first-hand experience of SWD studying online is a missing perspective. Accordingly, we aimed to explore their experience, using thematic analysis of semi-structured interviews involving ten SWD. Three themes emerged: (1) having control over studies as an advantage of online learning, (2) personal touch helps SWD’s online learning, and (3) challenges SWD experience with the social element of online learning. Our findings will help to develop the inclusivity of online learning to a new level.  相似文献

Identity Politics and the Queering of Art Education: Inclusion and the Confessional Route to Salvation     

Nicholas Addison 《The International Journal of Art & Design Education》2007,26(1):10-20

In this article I discuss the relationship between theories of identity and making practices in secondary art and design. Of particular interest is the way students are invited to explore identities in relation to a sense of self and the extent to which this is informed by schools' concern to make diversity visible through multicultural celebration, thus framing and possibly limiting exploration. It is notable that non‐heternormative sexual identities remain largely invisible in the official curriculum and I examine the disjunction between this absence and their hypervisibilty in the mass media and its culture of confession/exposure. I revisit Michel Foucault's discussion of the history of sexuality as a way to understand the development of confessional discourses in modern culture and to provide an alternative and ambivalent reading of the power relations implicit in work exploring identities by art and design students. Specifically, I look at the position of gay and lesbian students and teachers, and ask whether their sexuality can figure within the injunction ‘explore your identity’. Given the heteronormative culture of schooling, I end by recommending that individuals should be wary of outing themselves in the name of self‐expression but that art teachers could use strategies of distancing to engage students with issues of sexuality and join with others to counter homophobia by queering the curriculum.  相似文献   

Parental abusive versus supportive behaviors and their relation to hostility and aggression in young adults     

Karen B. Nicholas  Stephen L. Bieber 《Child abuse & neglect》1996,20(12):1195-1211

The relation of parental support to abuse has rarely been considered in research on the sequelae of childhood abuse in adulthood. In this study, using the Exposure to Abusive and Supportive Environments Parenting Inventory (EASE-PI), young adults who reported higher emotionally abusive parenting (EA) consistently reported significantly lower love and support from both parents. The relation between physically abusive parenting (PA) and love/support depended upon gender of parent and child. EA was significantly related to higher hostility and higher aggression, as measured by the Buss-Durkee Hostility Inventory, for both men and women, and to reports of physical fights within the family, for women only. PA was significantly related to higher aggression but not higher hostility. Lower support by fathers, but not by mothers, was significantly related to higher hostility. However, lower support of daughters by mothers was significantly related to increased physical fights in the family. Results indicate that less severe abusive behaviors, especially EA, may have detrimental outcomes of hostility and aggression and that supportive behaviors by both mothers and fathers may be important factors in the outcome.  相似文献   

The Determinants of Students' Perceived Learning Outcomes and Satisfaction in University Online Education: An Empirical Investigation*   总被引：1，自引：0，他引：1  

Sean B. Eom  H. Joseph Wen  Nicholas Ashill 《Decision Sciences Journal of Innovative Education》2006,4(2):215-235

In this study, structural equation modeling is applied to examine the determinants of students' satisfaction and their perceived learning outcomes in the context of university online courses. Independent variables included in the study are course structure, instructor feedback, self‐motivation, learning style, interaction, and instructor facilitation as potential determinants of online learning. A total of 397 valid unduplicated responses from students who have completed at least one online course at a university in the Midwest were used to examine the structural model. The results indicated that all of the antecedent variables significantly affect students' satisfaction. Of the six antecedent variables hypothesized to affect the perceived learning outcomes, only instructor feedback and learning style are significant. The structural model results also reveal that user satisfaction is a significant predictor of learning outcomes. The findings suggest online education can be a superior mode of instruction if it is targeted to learners with specific learning styles (visual and read/write learning styles) and with timely, meaningful instructor feedback of various types.  相似文献   

Progress report on the development of child abuse prevention, identification, and treatment systems in Eastern Europe

PROBLEM: After the Soviet Union dissolved in 1989, it became apparent that there was little recognition of the problems of child abuse and neglect, professionally, legally, or societally. There were no effective systems or laws in place to deal with these problems. METHOD: Beginning in 1995 the Children's Mental Health Alliance, in conjunction with the Open Society Institute began conducting trainings in Eastern Europe [Journal of the American Academy of Child Adolescent Psychiatry 39 (2000) 660]. Originally 18 countries from the Baltics to the Balkans participated. A program was elaborated which would proceed in several stages: (1) training mental health professionals to deal with child abuse and neglect (CAN); (2) teaching multidisciplinary team work and fostering the development of multidisciplinary NGOs focused on CAN; (3) promoting the self-sufficiency of these NGO's which would then facilitate social and legal reform and increase public awareness of the problem. Specific methods included multi-national trainings, assignment of mentors to the developing teams who maintained weekly contact with the teams and made yearly site visits to their countries, and overseeing project grants from OSI. RESULTS: NGO's had been established and registered in 11 countries, many establishing a network of programs within their countries. By 2000, over 3800 mental health professional had been trained, either directly by the program or by the trainees of the program. By the end of 2000, over 17,000 other professionals (lawyers, police, judges, educators, other physicians, etc.) had been trained by the network. CONCLUSION: While more work needs to be in this region, the teams in 11 countries have made solid starts.  相似文献

Poverty Experiences of Young Children and the Quality of Their Home Environments   总被引：3，自引：0，他引：3  

Patricia Garrett  Nicholas Ng'andu  John Ferron 《Child development》1994,65(2):331-345

This paper assesses the relative contribution of maternal, household, child, and poverty characteristics to the quality of the home environment. The sample consists of 1,887 children birth to 4 years old from the National Longitudinal Survey of Youth (NLSY). Ordinary least-squares regression is used to explore conceptually distinct aspects of children's poverty experiences. Poverty variables are found to have a statistically significant effect on the quality of the home environment, after controlling for the effects of other variables in the models. Statistically significant interactions among poverty variables are identified. A major finding is that improvements in family income have the strongest effects on the quality of the home environment for children who were born poor or lived much of their lives in poverty. The conclusion emphasizes implications for future research.  相似文献
