Teaching databases in compliance with the European dimension of higher education: Best practices for better competences     

M. Mercedes Martínez-González  Gérald Duffing 《Education and Information Technologies》2007,12(4):211-228

The Convergence process in which European Union (EU) universities are at present involved supposes that these institutions not only have to re-structure their degree programmes, but also their teaching and learning methodologies. We study the impact of this EU process on Database teaching, comparing the practices of three different European universities and using the Convergence goals as criteria. In our discussion, we identify which aspects in each university are closer to the Convergence goals, and which are likely to help in achieving these goals.  相似文献   

Reaction to videocolposcopy in the assessment of child sexual abuse.     

V J Palusci  T A Cyrus 《Child abuse & neglect》2001,25(11):1535-1546

OBJECTIVE: The purpose of this study was to clinically assess children's reactions to videocolposcopy with real-time observation of magnified anogenital images (VCO), and to evaluate whether these reactions are affected by patient or other characteristics such as response to preparation, disclosure of child sexual abuse (CSA), or examination findings. METHOD: Consecutive cases of children ages less than 18 years referred to a children's hospital clinic for nonemergent evaluation of suspected CSA during 1997 through 1999 were studied. We noted the child's response with clinical observation before and after videocolposcopy, and used the Genital Examination Distress Scale (GEDS) after evaluation. We compared these responses to patient gender, age, ethnicity, pubertal status, disclosure of child sexual abuse (CSA), and physical examination findings using univariate and regression analyses. RESULTS: Two hundred twenty-seven children (mean age 7.2 years, range 0-17) underwent videocolposcopy, of whom 55.1% disclosed sexual abuse and 17.2% had a positive examination. More than 80% were female, prepubertal, and non-Hispanic White. Most (85%) watched their examination on the monitor and were either cooperative or enthusiastic before and after videocolposcopy. Fewer very young children (ages 0-3 years) or female adolescents (13-17 years) watched the monitor. Summed GEDS scores were strongly correlated with observed responses after the procedure (p = .01), and children with CSA disclosure were three times more likely to watch the monitor and five times more likely than those without disclosure to have improved comfort. Other patient characteristics were not significantly associated with patient reaction to VCO. CONCLUSIONS: Most children are interested in watching their anogenital examination using magnified real-time images obtained during videocolposcopy and tolerate the procedure well. The GEDS is highly correlated with subjective clinical observation. While some children may particularly benefit from participating in their examination by using VCO, long-term effects of the evaluation and any relationship of a child's reaction to videocolposcopy with their history of sexual victimization remain to be established.  相似文献   

What catches the eye in class observation? Observers’ perspectives in a multidisciplinary peer observation of teaching program     

Ana Cristina Torres  Amélia Lopes  Jorge M. S. Valente  Ana Mouraz 《Teaching in Higher Education》2017,22(7):822-838

Peer Observation of Teaching has raised a lot of interest as a device for quality enhancement of teaching. While much research has focused on its models, implementation schemes and feedback to the observed, little attention has been paid to what the observer actually sees and can learn from the observation. A multidisciplinary peer observation of teaching program is described, and its data is used to identify the pedagogical aspects to which lecturers pay more attention to when observing classes. The discussion addresses the valuable learning opportunities for observers provided by this program, as well as its usefulness in disseminating, sharing and clarifying quality teaching practices. The need for further research concerning teacher-student relationships and students’ engagement is also suggested.  相似文献   

Individual performance across motoric self-regulation tasks are not correlated for pet dogs     

Alizée A. A. Vernouillet  Laura R. Stiles  J. Andrew McCausland  Debbie M. Kelly 《Learning & behavior》2018,46(4):522-536

Inhibitory control, the ability to restrain a prepotent but ineffective response in a given context, is thought to be indicative of a species’ cognitive abilities. This ability ranges from “basic” motoric self-regulation to more complex abilities such as self-control. During the current study, we investigated the motoric self-regulatory abilities of 30 pet dogs using four well-established cognitive tasks – the A-not-B Bucket task, the Cylinder task, the Detour task, and the A-not-B Barrier task – administered in a consistent context. One main goal of the study was to determine whether the individual-level performance would correlate across tasks, supporting that these tasks measure similar components of motoric self-regulation. Dogs in our study were quite successful during tasks requiring them to detour around transparent barriers (i.e., the Cylinder and Detour tasks), but were less successful with tasks requiring the production of a new response (i.e., A-not-B Bucket and A-not-B Barrier tasks). However, individual dog performance did not correlate across tasks, suggesting these well-established tasks likely measure different inhibitory control abilities, or are strongly influenced by differential task demands. Our results also suggest other aspects such as perseveration or properties of the apparatus may need to be carefully examined in order to better understand canine motoric self-regulation or inhibitory control more generally.  相似文献   

Stitching Codeable Circuits: High School Students’ Learning About Circuitry and Coding with Electronic Textiles     

Breanne K. Litts  Yasmin B. Kafai  Debora A. Lui  Justice T. Walker  Sari A. Widman 《Journal of Science Education and Technology》2017,26(5):494-507

Learning about circuitry by connecting a battery, light bulb, and wires is a common activity in many science classrooms. In this paper, we expand students’ learning about circuitry with electronic textiles, which use conductive thread instead of wires and sewable LEDs instead of lightbulbs, by integrating programming sensor inputs and light outputs and examining how the two domains interact. We implemented an electronic textiles unit with 23 high school students ages 16–17 years who learned how to craft and code circuits with the LilyPad Arduino, an electronic textile construction kit. Our analyses not only confirm significant increases in students’ understanding of functional circuits but also showcase students’ ability in designing and remixing program code for controlling circuits. In our discussion, we address opportunities and challenges of introducing codeable circuit design for integrating maker activities that include engineering and computing into classrooms.  相似文献   

A Quasi-Experiment Examining Expressive and Receptive Vocabulary Knowledge of Preschool Head Start Children Using Mobile Media Apps     

Angela Vatalaro  Anne McDonald Culp  Debbie L. Hahs-Vaughn  Amanda C. Barnes 《Early Childhood Education Journal》2018,46(4):451-466

This study examined the efficacy of using different types of mobile media apps to increase the receptive and expressive vocabulary development of 3-, 4-, and 5-year-old preschool children living in economically disadvantaged communities. Children and teachers in four Head Start classrooms participated in the quasi-experimental study, which included an 8-week intervention in which the children interacted with one of two types of apps: one classroom used four scaffolding-like vocabulary apps for an average of 1.8 h per day (n?=?16) and one classroom used four open-ended vocabulary apps for an average of 1.3 h per day (n?=?15). Two classrooms served as comparison groups (n?=?18; n?=?14) which used apps that were chosen by the Head Start program with no specific instructional method for approximately 1 h per day. Children’s vocabulary was assessed pre- and post-intervention using the PPVT-4, the EVT-2, and iPad Receptive and Expressive Vocabulary Assessments. Using a repeated measures analysis of variance with split plot analysis, children who used scaffolding-like vocabulary apps performed statistically significantly higher on the PPVT-4 than children who used open-ended vocabulary apps. There were no significant differences between groups on the EVT-2. The study contributed to the literature on teacher instruction of utilizing scaffolding-like apps to increase preschool vocabulary knowledge.  相似文献

Experiential learning and values education at a school youth camp: Maintaining Jewish culture and heritage     

Zehavit Gross  Suzanne D. Rutland 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2017,63(1):29-49

In our post-modern, globalised world, there is a risk of unique cultural heritages being lost. This loss contributes to the detriment of civilization, because individuals need to be rooted in their own specific identity in order to actively participate in community life. This article discusses a longitudinal case study of the efforts being made by Australian Jewish schools to maintain Jewish heritage through annual experiential religious education camps, coordinated in a programme called Counterpoint. The researchers’ aim was to analyse how a school youth camp can serve as a site for socialisation and education into a cultural and religious heritage through experiential learning and informal education. During research trips which took place over several years, interviews enabling insights into the process of experiential education were conducted with a total of three different Directors of Informal Jewish Education, two Jewish Studies heads, five participating teachers, seven youth leaders, as well as seven student focus groups. In their analysis of the semi-structured interviews, the authors of this article employed a grounded theory approach using a constant comparative method, which enabled a more nuanced understanding of the main phenomenon investigated. Over the years, they were able to observe two philosophical approaches, one of which focused more on socialisation, with immersion into experience, while the other focused on education, with immersion into Jewish knowledge. Their findings reveal that some educators aim to “transmit” knowledge through “evocation”, with the students involved in active learning; while others focus more on students’ “acquisition” of knowledge through transmission. Experiential learning activities were found to be more meaningful and powerful if they combined both approaches, leading to growth.  相似文献   

Stress analysis of anisotropic thick laminates in cylindrical bending using a semi-analytical approach   总被引：1，自引：0，他引：1  

LU Chao-feng LIM C.W. XU Feng 《浙江大学学报(A卷英文版)》2007,8(11):1740-1745

Semi-analytical elasticity solutions for bending of angle-ply laminates in cylindrical bending are presented using the state-space-based differential quadrature method (SSDQM). Partial differential state equation is derived from the basic equations of elasticity based on the state space concept. Then, the differential quadrature (DQ) technique is introduced to discretize the longitu- dinal domain of the plate so that a series of ordinary differential state equations are obtained at the discrete points. Meanwhile, the edge constrained conditions are handled directly using the stress and displacement components without the Saint-Venant principle. The thickness domain is solved analytically based on the state space formalism along with the continuity conditions at interfaces. The present method is validated by comparing the results to the exact solutions of Pagano’s problem. Numerical results for fully clamped thick laminates are presented, and the influences of ply angle on stress distributions are discussed.  相似文献   

It’s About Making Surfaces Invisible     

Geethamma V. G.  Kazuki Shigeta  John A. Rogers 《Resonance》2018,23(4):423-438

Antireflection is an essential requirement for certain optoelectronic devices. Antireflective surfaces can be generated by different methods. One method mimics the nanofeatures on the moth eye surface. This can be done by ‘soft lithography’ (SL), where nanofeatures are created on an elastomeric stamp. This stamp is then used for imprinting the pattern on other surfaces.  相似文献
