The role of parents and peers in understanding female adolescent sexuality – testing perceived peer norms as mediators between some parental variables and sexuality     

Linda Rajhvajn Bulat  Marina Ajduković  Dea Ajduković 《Sex education》2016,16(5):455-470

Previous research has confirmed peers and parents as significant agents of socialisation with respect to young people’s sexuality. The aim of this cross-sectional cohort study was to examine how parental and peer variables predict young women’s sexual behaviour and sexuality-related thoughts and emotions, and whether perceived peer influences mediate the relationship between parental variables and young person sexuality. A total of 560 female high school students of 1st (mean age 15.56 years) and 3rd grade (mean age 17.55 years), selected by means of two-stage stratified probability sampling participated in the research. Results confirmed that peer variables explained considerably more variance in participant sexuality than parental variables. Indirect parental communication about sexuality was a significant positive predictor of sexual behaviour and sexuality-related thoughts and emotions in both subsamples. The strength of direct and indirect influences of parents and peers on young people’s sexuality is determined by the age of the young person and specific aspects of adolescent sexuality. Perceived percentage of sexually active peers was the only mediator in older participants, while in the younger subsample, additional peer variables mediated the association between some parental and sexuality variables. In the discussion, special attention is given to implications of these results for planning future forms of comprehensive sexual education.  相似文献   

Ultrasound and cadaveric prosections as methods for teaching cardiac anatomy: a comparative study     

Griksaitis MJ  Sawdon MA  Finn GM 《Anatomical sciences education》2012,5(1):20-26

This study compared the efficacy of two cardiac anatomy teaching modalities, ultrasound imaging and cadaveric prosections, for learning cardiac gross anatomy. One hundred and eight first-year medical students participated. Two weeks prior to the teaching intervention, students completed a pretest to assess their prior knowledge and to ensure that groups were equally randomized. Students, divided into pre-existing teaching groups, were assigned to one of two conditions; "cadaver" or "ultrasound." Those in the cadaver group received teaching on the heart using prosections, whereas the ultrasound group received teaching using live ultrasound images of the heart. Immediately after teaching, students sat a post-test. Both teaching modalities increased students' test scores by similar amounts but no significant difference was found between the two conditions, suggesting that both prosections and ultrasound are equally effective methods for teaching gross anatomy of the heart. Our data support the inclusion of either cadaveric teaching or living anatomy using ultrasound within the undergraduate anatomy curriculum, and further work is needed to compare the additive effect of the two modalities.  相似文献

University access and after: explaining the social composition of degree programmes and the contrasting expectations of students     

Helena Troiano  Marina Elias 《Higher Education》2014,67(5):637-654

University expansion in higher education has been hierarchically differentiated. There is some concentration of certain social profiles in some degrees of study, so social composition between degrees can vary considerably. This article describes in terms of social composition 10 degrees of four public universities in the metropolitan area of Barcelona. We analyse 857 questionnaires filled in by mid-career students. From the perspective of agent’s decision on the choice of studies, we explore what were the factors that made them choose a concrete degree. We examine several variables that can indicate whether their expectations have been met or not. The results show that the factors predicted by the theory by which working-class (WC) students choose degrees—instrumental motivations and conditions that minimize the risk—are often met. In this regard, the recent structural reform related with the implementation of the European Higher Education Area that removes short-cycles degrees (3 years) could lead to a problem of access for WC students.  相似文献   

Participant characteristics and process variables predict attrition from a home-based early intervention program     

Tilman Brand  Tanja Jungmann 《Early childhood research quarterly》2014

Although advocates of home visits claim that they improve access to preventive interventions for socially disadvantaged families, home visiting programs often report high dropout rates. This study investigated factors predicting attrition in a sample of 434 low-income, first-time mothers in a German program modeled on the Nurse–Family Partnership program. Both participant characteristics and process variables associated with attrition were examined. The results indicated that 38.5% of the mothers left the program before completing 75% of the enrollment time; 62% of those left for addressable reasons (e.g., losing interest in program participation). Arguably, these participants might be retained through program modifications. Almost half of the dropouts left the program before completing 25% of the enrollment time. Program dropouts were younger and did not experience pregnancy-related risks. With regard to process variables, a high frequency of unsuccessful visit attempts and low maternal engagement during the home visits increased the risk for attrition. Self-referral, a high percentage of time spent on parenting issues as well as a high percentage of grandmother participation during visits contributed to participant retention. Among mothers with a high number of risk factors for child abuse and neglect, partner (husband or boyfriend) participation during visits positively influenced the retention rate. Since process variables explained a larger amount of variance in attrition compared to participant characteristics, it is reasonable to focus on the intervention processes when trying to reduce attrition.  相似文献   

Cognitive preconditions of early reading and spelling: a latent-variable approach with longitudinal data     

Anna-Lena Preßler  Tanja Könen  Marcus Hasselhorn  Kristin Krajewski 《Reading and writing》2014,27(2):383-406

The aim of the present study was to empirically disentangle the interdependencies of the impact of nonverbal intelligence, working memory capacities, and phonological processing skills on early reading decoding and spelling within a latent variable approach. In a sample of 127 children, these cognitive preconditions were assessed before the onset of formal education, whereas reading as well as spelling achievement was measured at the end of grade 1. The findings indicate that working memory does contribute to the prediction of early reading and spelling, and that this contribution outperforms that of general intelligence and phonological recoding from long-term memory during the early steps of reading and spelling acquisition. Moreover, the results show that phonological awareness mediates the effects of working memory capacities on early literacy outcomes. The role of working memory and phonological awareness as key cognitive preconditions of early reading and spelling are discussed.  相似文献   

Assessing Long-Term Effects of Inquiry-Based Learning: A Case Study from College Mathematics     

Marina Kogan  Sandra L. Laursen 《Innovative Higher Education》2014,39(3):183-199

As student-centered approaches to teaching and learning are more widely applied, researchers must assess the outcomes of these interventions across a range of courses and institutions. As an example of such assessment, this study examined the impact of inquiry-based learning (IBL) in college mathematics on undergraduates’ subsequent grades and course selection at two institutions. Insight is gained upon disaggregating results by course type (IBL vs. non-IBL), by gender, and by prior mathematics achievement level. In particular, the impact of IBL on previously low-achieving students’ grades is sizable and persistent. The authors offer some methodological advice to guide future such studies.  相似文献

The current experiment employed a mixed design to assess word learning in 70 infants under the age of 2. Infants (4–24 months) were randomly assigned to watch 1 of 2 educational DVDs in their homes, 6 times over a 2-week period. The 2 DVDs were identical except that each contained 3 different low frequency words (e.g., lens). In addition, participants were randomly assigned to a mediation condition, where parents were told to watch with their child and call attention to the DVD and the words being taught; controls were instructed to allow their child to watch alone. The stimulus DVDs were designed to mimic a commercially available DVD such as Baby Einstein. Following the 2-week exposure period, participants were brought to the testing location and tested on all 6 words, both those that were included in the DVD they were exposed to and those that appeared in the other DVD. Results suggested that infants 17 months and older benefitted from repeat exposure to the DVD; whereas younger infants did not. In addition, mediation did not seem to aid in children's learning from the DVD; although not all parents in the mediation condition complied.  相似文献   

Teaching Information Literacy Courses in The Context of Library and Information Science Education in Bulgaria: Challenges and Innovative Approaches     

Marina Encheva 《图书馆管理杂志》2013,53(5):595-602

ABSTRACT

The article examines the application of innovative approaches in the information literacy training of library and information science students in Bulgaria. The change of the educational paradigm in the field is presented based on recent developments in one of the oldest Bulgarian institutions that prepares librarians and information specialists—the State University of Library Studies and Information Technologies. The active learning strategies suitable for information literacy skills development courses are studied by the use of three methods: “learning by doing,” “interaction in the learning group,” “learning by trial and error” within the practical training of students. The prospects for transforming information literacy instruction through the elaboration of digital educational games and a game-based learning model in the frame of the international project tiLIT are also outlined.  相似文献
