Comparisons of adopted and nonadopted adolescents in a large, nationally representative sample

There are conflicting findings about whether adopted children have more psychological and behavioral problems than nonadoptees. Research results are discrepant partly because many previous studies were based on small clinical samples or on samples biased by self-selection. A nationally representative school survey (Add Health) was used to compare adopted (n = 1,587) and nonadopted adolescents (total N = 87,165) across a wide variety of measures. Standardized mean differences show that adopted adolescents are at higher risk in all of the domains examined, including school achievement and problems, substance use, psychological well-being, physical health, fighting, and lying to parents. Demographic and background variable breakdowns show that the effect sizes for differences between adopted and nonadopted adolescents were larger for males, younger or older adolescents, Hispanics or Asians, and adolescents living in group homes or with parents of low education. Distributional analyses revealed approximately a 1:1 ratio of adopted to nonadopted adolescents in the middle ranges of the outcome variables but a ratio of 3:1 or greater near the tails of the distributions. These data clearly show that more adopted adolescents have problems of various kinds than their nonadopted peers; effect sizes were small to moderate based on mean differences, but comparisons of distributions suggest much larger proportions of adopted than nonadopted adolescents at the extremes of salient outcome variables.  相似文献

The Relationship between Behavioral Inattention,Meta‐Attention,and Graduate Students' Online Information Seeking     

Brittany Burek  Rhonda Martinussen 《Mind, Brain, and Education》2021,15(1):111-121

Success in postsecondary education requires proficiency with academic online information seeking. Navigating the internet to find information is a complicated task that is vulnerable to lapses in attention. This study examined the relationships among Canadian graduate students' self‐reported behavioral inattention symptoms, awareness and regulation of attentional focus (meta‐attention), and online academic information seeking abilities. One‐hundred and thirteen (99 female) graduate students (83 master's level, 27 doctoral level) completed an online self‐report questionnaire examining domain‐ and strategic‐experience, behavioral inattention symptoms, meta‐attention, and online information seeking ability. Results indicated that self‐reported inattention symptoms, both components of meta‐attention and domain experience each significantly predicted unique variance in online information seeking ability. Implications for research and intervention are discussed.  相似文献   

Incongruities as a source of organizational renewal in corporate management of R&D     

Jens Frslev Christensen 《Research Policy》2002,31(8-9)

The heydays of the central R&D laboratory as the ‘dominant design’ of corporate R&D in large technology-intensive companies is over. The last decades have witnessed not only downsizing of central R&D, but also ongoing experimentation and restructuring of the modes of managing corporate R&D. What is the logic behind these ongoing restructurings? The paper argues that different kinds of organizational incongruities constitute critical sources of change in the organization of R&D. The paper seeks to align a contingency and an evolutionary perspective in analyzing two Danish technology-intensive companies characterized by highly different organizational trajectories.  相似文献

Casual Games and Casual Learning About Human Biological Systems     

C. Aaron Price  Katherine Gean  Claire G. Christensen  Elham Beheshti  Bryn Pernot  Gloria Segovia  Halcyon Person  Steven Beasley  Patricia Ward 《Journal of Science Education and Technology》2016,25(1):111-126

Casual games are everywhere. People play them throughout life to pass the time, to engage in social interactions, and to learn. However, their simplicity and use in distraction-heavy environments can attenuate their potential for learning. This experimental study explored the effects playing an online, casual game has on awareness of human biological systems. Two hundred and forty-two children were given pretests at a Museum and posttests at home after playing either a treatment or control game. Also, 41 children were interviewed to explore deeper meanings behind the test results. Results show modest improvement in scientific attitudes, ability to identify human biological systems and in the children’s ability to describe how those systems work together in real-world scenarios. Interviews reveal that children drew upon their prior school learning as they played the game. Also, on the surface they perceived the game as mainly entertainment but were easily able to discern learning outcomes when prompted. Implications for the design of casual games and how they can be used to enhance transfer of knowledge from the classroom to everyday life are discussed.  相似文献   

I still wanna be an engineer! Women,education and the engineering profession   总被引：1，自引：1，他引：0  

Judith Gill  Rhonda Sharp  Julie Mills  Suzanne Franzway 《European Journal of Engineering Education》2008,33(4):391-402

Women's low enrolment in post-school engineering degrees continues to be a problem for engineering faculties and the profession generally. A qualitative interview-based study of Australian women engineers across the range of engineering disciplines showed the relevance of success in math and science at school to their enrolling in engineering at university. However, for a significant number of the women the positive self-image connected with school success was not maintained by their workplace experience. Using a mixed methods approach, further investigations of the attitudes and experiences of working engineers at three large firms suggest that engineering workplaces continue to be uneasy environments for professional women. Particular issues for women working as professional engineers are identified in this paper and some educational strategies are suggested in order to better prepare engineers for an inclusive and participatory professional life.  相似文献   

Factors That Influence Self‐Efficacy of Counseling Students: An Exploratory Study     

Mei Tang  Kathleen D. Addison  Danielle LaSure‐Bryant  Rhonda Norman  William O'Connell  Joseph A. Stewart‐Sicking 《Counselor Education & Supervision》2004,44(1):70-80

The study examined whether age, prior work experience, number of courses taken, and number of internship hours have a positive relationship with counseling self‐efficacy. Participants were 116 counselor education students. The results from correlation and multivariate analyses of covariance revealed that the length of internship hours and prior related work experience were positively correlated with counseling self‐efficacy. The differences in counseling anxiety, affection adjustment, and assessment found between the students in programs accredited by the Council for Accreditation of Counseling and Related Educational Programs (CACREP) and those in non‐CACREP‐accredited programs disappeared when the background variables were controlled as covariates.  相似文献   

Emerging Trends in Mathematics Education for People with Down Syndrome: Current Research and Future Directions     

Rhonda Faragher  Elena Gil Clemente 《International Journal of Disability, Development & Education》2019,66(2):111-118

ABSTRACT

In September 2017, a group of researchers met for the first conference devoted to the singular purpose of exploring a neglected field – the learning of mathematics by individuals with Down syndrome. This special issue is a result of that first meeting and identifies three emerging trends in the mathematics education of learners with Down syndrome: the goals, content, and pedagogy. Education is central to the goal of improving an individual’s quality of life and only recently has the impact of mathematics been fully comprehended. Many researchers continue to explore the development of the concept of number and there is still much to learn. As a new development, we see that interest is now expanding to explore other areas of mathematics. We still have a long way to go to understand how best to open the doors of mathematics to all learners with Down syndrome. We conclude by offering six areas requiring immediate future research in the field of mathematics and Down syndrome.  相似文献
