Validation of a learning hierarchy for the mole concept     

Alan K. Griffiths  Heidi Kass  Alan G. Cornish 《科学教学研究杂志》1983,20(7):639-654

Three psychometric methods for validating learning hierarchies are applied to one data set derived from responses of grade 10 chemistry students to items representing the skills in a hypothesized hierarchy for the mole concept. Two methods which considered skills in pairs, namely the “test of inclusion” by White and Clark and the “ordering-theoretic method” by Airaisian and Bart produced generally similar results. The third method, by Dayton and Mac-ready, considered the hierarchy as a whole and produced clearer distinctions between alternative hierarchies than the first two methods. The hierarchy derived from this analysis was supported by a test for transfer of learning from subordinate to superordinate skills.  相似文献

Introduction to the special issue ‘How adolescents read and learn on the Web: internal and external factors (Introducción al número especial ‘Cómo leen y aprenden los adolescentes en la red: factores internos y externos’)

ABSTRACT

The World Wide Web has become a major information resource for adolescents (i.e., 10–19 years of age), offering an unprecedented amount of information on virtually any topic. While the Web can potentially offer new learning opportunities, it also presents several challenges. Reading and learning on the Web requires a set of advanced literacy skills that adolescents do not necessarily possess and need to develop in order to effectively deal with the complexity of information encountered online. This special issue brings together five empirical articles and a discussion paper that examine internal and external factors that are beneficial (or detrimental) to adolescents’ reading and learning on the Web, and contribute to explaining how young learners develop complex literacy skills. Theoretically, the special issue contributes to the conceptualization of what researchers refer to as ‘multiple documents literacy’. In practice, it informs researchers and educators of emerging empirical results regarding adolescents’ information behaviour, as well as on instructional strategies that can be effective for developing adolescents’ literacy skills.  相似文献   

A two‐component growth mindset intervention for young people with SEND     

Eloise de Carvalho  Yvonne Skipper 《Journal of Research in Special Educational Needs》2020,20(3):195-205

Interventions to increase the endorsement of the growth mindset (the belief that intelligence can be improved with effort) have been successfully implemented in schools. However, they rarely target children and young people with special educational needs and/or disabilities (SEND), a group who are more likely to endorse a fixed mindset, experience lower academic self‐concept and academic resilience, and be at risk of negative stereotyped attitudes. This quasi‐experimental study implemented a 10‐week PSHE programme as well as dedicated lessons with adapted classroom practices, for example, task framing and feedback, to promote the growth mindset message to young people with SEND (N = 18). Analyses of pre‐ to post‐intervention measures demonstrated moderate evidence for the intervention having increased students’ endorsement of the growth mindset, as well as anecdotal evidence for increased academic self‐concept, academic resilience and positive attitudes to disability. However, these effects were not sustained in follow‐up measures conducted 7 weeks post‐intervention. The intervention did not improve students’ academic performance. Although preliminary, findings demonstrate the viability of growth mindset interventions for children and young people with SEND, but suggest that interventions should be maintained for longer‐lasting effects.  相似文献   

Does More Intensive Neonatal Intensive Care Unit Follow-Up Service Result in Better Outcomes? A Cost-Effective Analysis     

Linda D. Goetze  Nancy Immel  Colette M. Escobar  Yvonne Gillette  Daniel Coury  Nancy Hansen 《Early education and development》1993,4(4):275-289

Little is known about the relative cost-effectiveness of the many different types of early intervention services provided to medically fragile infants and their families. This study compared two intensities of services for such infants and their families: (a) a coordinated and comprehensive system of early intervention services initiated prior to discharge from the NICU and designed to transition infants to community-based services were compared with the effects of services (high intensity); and (b) a more traditional hospital follow-up consisting of medical checkups and referrals following discharge (low intensity). High-intensity services resulted in five times more community-based early intervention hours for families and infants when compared with low-intensity services. Annual costs of the high-intensity group were approximately triple the costs of the low-intensity group ($10,814 versus $3,032 per child per year), but there were only a few statistically significant differences on measures of child and family functioning between the groups at 6-, 12-, 18-, and 24months' corrected age. Implications of these findings for research and practice are given.  相似文献   

Interagency collaboration between child protection and mental health services: practices, attitudes and barriers     

Darlington Y  Feeney JA  Rixon K 《Child abuse & neglect》2005,29(10):1085-1098

OBJECTIVE: The aim of this paper is to examine some of the factors that facilitate and hinder interagency collaboration between child protection services and mental health services in cases where there is a parent with a mental illness and there are protection concerns for the child(ren). The paper reports on agency practices, worker attitudes and experiences, and barriers to effective collaboration. METHOD: A self-administered, cross-sectional survey was developed and distributed via direct mail or via line supervisors to workers in statutory child protection services, adult mental health services, child and youth mental health services, and Suspected Child Abuse and Neglect (SCAN) Teams. There were 232 completed questionnaires returned, with an overall response rate of 21%. Thirty-eight percent of respondents were statutory child protection workers, 39% were adult mental health workers, 16% were child and youth mental health workers, and 4% were SCAN Team medical officers (with 3% missing data). RESULTS: Analysis revealed that workers were engaging in a moderate amount of interagency contact, but that they were unhappy with the support provided by their agency. Principle components analysis and multivariate analysis of variance (MANOVA) on items assessing attitudes toward other workers identified four factors, which differed in rates of endorsement: inadequate training, positive regard for child protection workers, positive regard for mental health workers, and mutual mistrust (from highest to lowest level of endorsement). The same procedure identified the relative endorsement of five factors extracted from items about potential barriers: inadequate resources, confidentiality, gaps in interagency processes, unrealistic expectations, and professional knowledge domains and boundaries. CONCLUSIONS: Mental health and child protection professionals believe that collaborative practice is necessary; however, their efforts are hindered by a lack of supportive structures and practices at the organizational level.  相似文献   

Can Low-Cost Online Summer Math Programs Improve Student Preparation for College-Level Math? Evidence From Randomized Experiments at Three Universities     

Matthew M. Chingos  Rebecca J. Griffiths 《Journal of research on educational effectiveness》2017,10(4):794-816

Every year many students enter college without the math preparation needed to succeed in their desired programs of study. Many of these students struggle to catch up, especially those who are required to take remedial math courses before entering college-level math. Increasing the number of students who begin at the appropriate level of math has become an important focus for educators and policymakers. We conducted randomized experiments of low-cost online summer math programs at three universities to test whether this type of intervention can increase access to math preparation, improve placement and enrollment in fall math classes, and improve performance in first-year math courses. Students who received the intervention engaged with the platform, though at relatively low rates, and were more likely to retake the placement test and improve their scores than students in the control group. However, these improved scores did not translate into enrolling in higher level math courses, obtaining more math credits, or improving grades in math-related courses during the first year of college. Thus, providing students access to this online tool did not improve their math skills.  相似文献   

Socioeconomic status and health in adolescents: the role of stress interpretations   总被引：6，自引：0，他引：6  

Chen E  Langer DA  Raphaelson YE  Matthews KA 《Child development》2004,75(4):1039-1052

The role of psychological interpretations in the relationship between low socioeconomic status (SES) and physiological responses was tested. One hundred high school students (ages 15–19) watched videos of ambiguous and negative life situations, and were interviewed about their interpretations. Lower SES was associated with greater threat interpretations during ambiguous (but not negative) situations and with greater diastolic blood pressure and heart rate reactivity. Threat interpretations partially mediated relationships between SES and reactivity. General life events (e.g., lack of positive life events), rather than specific life events (e.g., exposure to violence), partially explained the relationship between low SES and threat interpretations. Results suggest that the larger social environment helps explain how adolescents approach new social situations, which in turn has implications for adolescent physical health.  相似文献
