Representation of situations involving changes sequence: A didactic interdisciplinary intervention     

Nadine Bednarz  Catherine Garnier 《European Journal of Psychology of Education - EJPE》1993,8(2):135-149

Our previous research, conducted in various fields, demonstrates the obvious difficulties children encounter when they must achieve, in a collective game situation, coordinated motor actions (Garnier, 1989) or solve additive problems in mathematics involving changes sequence (Bednarz Schmidt, & Dufour-Janvier, 1989b; Poirier & Bednarz. 1991a, b). These investigations show the children’s extreme centration on the states, and a global non anticipation of the situations that lead them to act punctually and sequentially. The didactic intervention that was developed in view of these difficulties, integrating sociomotor and mathematics activity, aims to develop the cognitive processes of decentration and anticipation on the basis of the resolution of these situations. In the pedagogical approach undertaken on 30 grade three children (8–9 years old), the social actions and interactions played a major part in the development of the aimed processes and in the elaboration of the representation of underlying relations to the situations involved (games and problems). A sociomotor examination (collective game) and a written examination in mathematics, carried out before and after the experiment, show, along with the qualitative analysis achieved during the intervention, the evolution of the child jaced with the aimed processes.  相似文献   

Foster Youth Need Sex Ed,Too!: Addressing the Sexual Risk Behaviors of System-Involved Youth     

Nadine Finigan-Carr  Rochon Steward  Cathy Watson 《American journal of sexuality education》2018,13(3):310-323

ABSTRACT

The social, economic, and environmental determinants of health include employment, housing, and education; exposure to environmental factors like lead or access to healthy food; and poverty, racism and oppression. Many of these conditions can lead to Adverse Childhood Experiences that may put children and youth at risk for abuse or maltreatment leading to involvement in the child welfare or juvenile justice systems. All young people experience important developmental milestones on their path to becoming healthy adults, and while this time of change is full of promise, it can be a time of increased vulnerability or risk. For system-involved youth, navigating this time of change can be fraught with even more challenges or barriers. Without strong family and social networks, they may face increased risk of engaging in high-risk behaviors—such as unprotected sex and sex with multiple partners—as well as unintended pregnancy, HIV, and other sexually transmitted infections. Our study examined survey data to assess the overall sexual reproductive health behaviors for youth aged 14–21 in out-of-home care in an urban environment (n = 270; 60.7% male; 82% African American; 7.9% Latinx). Youth were recruited between 2012 and 2016; 76.4% of these teens had had sexual intercourse at some point in their lifetime. Of these, 86.0% were sexually active before the age of 16. Although there were numerous risk factors related to contraception and condom use as well as partner demographics, there were assets or strengths identified. A discussion of how these findings can be utilized to develop effective prevention intervention strategies is provided.  相似文献   

The effects of autonomy-supportive and controlling teaching behaviour in biology lessons with primary and secondary experiences on students’ intrinsic motivation and flow-experience     

Natalia Hofferber  Melanie Basten  Nadine Großmann 《International Journal of Science Education》2016,38(13):2114-2132

Self-Determination Theory and Flow Theory propose that perceived autonomy fosters the positive qualities of motivation and flow-experience. Autonomy-support can help to maintain students’ motivation in very interesting learning activities and may lead to an increase in the positive qualities of motivation in less interesting learning activities. This paper investigates whether autonomy-supportive or controlling teaching behaviour influence students’ motivation and flow-experience in biology class. In study 1, 158 students of grade six worked on the adaptations of Harvest Mice (Micromys minutus) with living animals. The 153 sixth graders of study 2 dealt with the same content but instead worked with short films on laptops. Previous studies have shown that students perceive film sequences as less interesting than working with living animals. Students’ intrinsic motivation and flow-experience were measured at the end of the first and the third lesson. In study 1, autonomy-supportive teaching behaviour led to significant differences in students’ intrinsic motivation and flow-experience when compared to controlling teaching behaviour. In study 2, motivation and flow-experience were not always in line with theory. The positive effects of autonomy-supportive and the non-beneficial effects of the controlling teaching behaviour seem to be dependent on the interestingness of the teaching material.  相似文献

The impact of adverse childhood experiences on an urban pediatric population     

Burke NJ  Hellman JL  Scott BG  Weems CF  Carrion VG 《Child abuse & neglect》2011,35(6):408-413

Objective

The goal of this study was to investigate the adverse childhood experiences (ACEs) in youth in a low-income, urban community.

Study design

Data from a retrospective chart review of 701 subjects from the Bayview Child Health Center in San Francisco are presented. Medical chart documentation of ACEs as defined in previous studies were coded and each ACE criterion endorsed by a traumatic event received a score of 1 (range = 0-9). This study reports on the prevalence of various ACE categories in this population, as well as the association between ACE score and two pediatric problems: learning/behavior problems and body mass index (BMI) ≥ 85% (i.e., overweight or obese).

Results

The majority of subjects (67.2%, N = 471) had experienced 1 or more categories of adverse childhood experiences (ACE ≥ 1) and 12.0% (N = 84) had experienced 4 or more ACEs (ACE ≥ 4). Increased ACE scores correlated with increased risk of learning/behavior problems and obesity.

Conclusions

There was a significant prevalence of endorsed ACE categories in this urban population. Exposure to 4 or greater ACE categories was associated with increased risk for learning/behavior problems, as well as obesity.

Practice implications

Results from this study demonstrate the need both for screening of ACEs among youth in urban areas and for developing effective primary prevention and intervention models.  相似文献   

Improving students' reading comprehension skills: Effects of strategy instruction and reciprocal teaching     

Nadine Spörer  Joachim C. Brunstein  Ulf Kieschke 《Learning and Instruction》2009,19(3):272-286

The aim of this study was to investigate the effects of three different forms of strategy instruction on 210 elementary-school students' reading comprehension. Students were assigned to any one of three intervention conditions or to a traditional instruction condition (control condition). Training students were taught four reading strategies (summarizing, questioning, clarifying, predicting) and practiced these strategies in small groups (reciprocal teaching), pairs, or instructor-guided small groups. At both the post- and follow-up test the intervention students attained higher scores on an experimenter-developed task of reading comprehension and strategy use than the control students who received traditional instruction. Furthermore, students who practiced reciprocal teaching in small groups outperformed students in instructor-guided and traditional instruction groups on a standardized reading comprehension test.  相似文献

Borrowing From e-commerce; Are Recommender Systems Good for Libraries? For past 10 years recommender systems have attempted to match customers to materials in the e-commerce world. Utilizing specifically designed recommender systems to meet the needs of patrons, collaborative filtering, and content-based recommender systems are the two basic types with several hybrids created from these two have been significantly enhancing digital library services. Security issues come into play in a special way with libraries, and plagiarism can also affect recommender quality. Open Source tools may be the answer for libraries and their customers, enabling a better utilization of all that a library has to offer.  相似文献   

Dual market structures and the likelihood of repeated ties - evidence from pharmaceutical biotechnology     

Nadine Roijakkers  John Hagedoorn  Hans van Kranenburg 《Research Policy》2005,34(2):235-245

This paper analyses the role of repeated ties in the high-tech pharmaceutical biotechnology industry, a sector that is characterized by a strong dual market structure. Our most important finding is that previous ties in pairs of large pharmaceutical companies and small biotechnology firms have a negative effect on their subsequent partnering. An explanation for this result is found in the context of understanding the specifics of large-small coalitions in a high-tech dual market structure. Unlike what is known about repeated ties in many other industries, this high-tech dual market structure indicates that R&D partnerships between a small number of very large companies and a large group of dependent, small firms are not characterized by mutual dependence, similarity, or equality.  相似文献   

Making a good career choice: A decision-analytical intervention to enhance proactive decision-making and career choice self-efficacy in high school students     

Johannes Ulrich Siebert  Maxi Becker  Nadine Oeser 《Decision Sciences Journal of Innovative Education》2023,21(1):10-25

At the end of high school, teenagers must deal with the first life-changing decision of determining what to do after graduation. For these decisions, adolescents need to be able to make good choices. However, most schools have not yet implemented decision trainings into their curricula. A new intervention called “KLUGentscheiden!” was developed to train complex decision-making in high school students to close this gap. The intervention targets three key components of good decision-making: envisioning one's objectives, identifying relevant alternatives, and comparing the identified alternatives by a weighted evaluation. We assumed that successfully training those decision-analytical steps should enhance self-perceived proactive decision-making skills. In addition, the training should also enhance self-assessed career choice self-efficacy. The intervention was evaluated in a pseudorandomized control study including 193 high school students. Compared to a control group, the intervention group significantly increased proactive decision-making skills and career choice self-efficacy. Although different long-term evaluations are still pending, the KLUGentscheiden! intervention provides an important tool to train complex decision-making in high-school students. It also has the potential to apply to other career choices of young individuals, such as choosing majors, a final thesis, a job, or a field of work.  相似文献   

Understanding effects of COVID-19 on undergraduate academic stress,motivation and coping over time     

Lisa Fridkin  Neus Bover Fonts  Katie Quy  Nadine Zwiener-Collins 《Higher Education Quarterly》2023,77(4):623-637

The rapid and unprecedented shift from face-to-face instruction to remote online learning as a consequence of the COVID-19 pandemic had a substantial impact on teaching and learning in Higher Education: students had to adapt to a new way of learning, away from typical campus settings and their peers, and to new forms of assessments. This study examined academic stress, learning strategies, motivation and ways of coping from a sample of 177 unique students from a large London university, collecting primary data via survey at three time points during the academic year 2020/21 when teaching was remote and online only. Our findings show how patterns in academic stress, learning strategies, motivation and coping vary over the course of the academic year giving novel insight into how student learning and adaptation to the situation changed over time. We also report on differences in these patterns according to year group and for those students who are the first-in-family to attend university and those who are not. Based on these findings we identify priority areas where higher education institutions should support undergraduate students and provide evidence that some groups of students may need more and targeted support to secure their ongoing learning and well-being.  相似文献
