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   

Development of argumentative discourse based on learning demand / Evolución del discurso argumentativo en función de la demanda de aprendizaje     

Maribel Cano  Montserrat Castelló 《Infancia y Aprendizaje》2016,39(1):84-118

Abstract

This study is part of a larger project focused on the development of argumentative competence and its effect on knowledge construction. It aims to analyse and compare the changes in the evolution of the claims and the quality of the written arguments used by university students in two learning scenarios: a first scenario where students participated in a debate with the aim of convincing; and a second scenario where the debate was aimed at achieving an agreement by consensus. The participants were 77 first-year university students in Education and Speech Therapy. A quasi-experimental design was adopted with repeated measures, in which students from the two groups wrote two argumentative texts (initial and final) for each type of debate. The results indicate that the initial claims evolved towards more moderate positions at the end of the process; and the quality of the arguments that students wrote in their texts varied significantly depending on the type of demand and the time of writing (initial or final).  相似文献   

The efficiency of information transmission of sign and spoken language     

Ortiz IR  Roche JM 《American annals of the deaf》2008,152(5):480-494

Rhe study compares sign and oral language in terms of information transmission efficiency. The sample consisted of 36 hearing people with no knowledge of sign language and 36 deaf people reasonably fluent in sign language. (The deaf participants' level of hearing loss ranged from severe to profound.) Oral and sign language comprehension was assessed by means of texts at three different difficulty levels. After being exposed to the texts, the study participants had to tell what they had understood about them, answer a set of related questions, and offer a title for each text. When the hearing group's comprehension of oral versions of the texts was compared to the deaf group's comprehension of signed versions, the deaf group showed better comprehension of the explicit content of the texts but added more invented content and made more errors.  相似文献

Comparison between conceptions and assessment practices among secondary education teachers: more differences than similarities (Comparación entre concepciones y prácticas de evaluación en profesores de Educación Secundaria: más diferencias que semejanzas)     

Javier Fernández-Ruiz  Ernesto Panadero 《Infancia y Aprendizaje》2020,43(2):309-346

ABSTRACT

Teachers’ conceptions can affect any teaching practice, including assessment. Compared with the previous learning stages in Spain, the accreditation-based focus increases in secondary education. Therefore, it is necessary to study the conceptions teachers have of assessment during this stage and the role these play in their teaching practices. The study participants comprised 219 secondary education teachers. A mixed methodology including a questionnaire, dilemmas and the analysis of test contents was used. An analysis was implemented of the relationship between the conceptions of assessment and the type of tests used, self-assessment and peer assessment, and characteristics of feedback. The teachers reported having a formative conception, but this was incoherent with their assessment methods characterized by a scarce use of self-assessment and peer assessment and a hardly formative feedback. In conclusion, we highlight the relevance of the teaching-related conceptions in the education system and the need for working jointly with teachers to implement an authentically formative assessment in the classroom, with an emphasis on consistency between conceptions and practices.  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   

A Conceptual Change Teaching Strategy to Facilitate High School Students' Understanding of Electrochemistry   总被引：1，自引：0，他引：1  

Niaz  Mansoor  Chacón  Eleazar 《Journal of Science Education and Technology》2003,12(2):129-134

Recent research in chemistry education has shown an increasing interest in the facilitation of conceptual change in student understanding of chemical concepts. Most of the studies have tried to show the difference in student performance on algorithmic and conceptual problems. The objective of this study is to go beyond and design a teaching strategy based on two teaching experiments that could facilitate students' conceptual understanding of electrochemistry. The study is based on two sections (control, n = 29; experimental, n = 28) of 10th grade high school students at a public school in Venezuela. Experimental group participated in two teaching experiments designed to generate situations/experiences in which students are forced to grapple with alternative responses leading to cognitive conflicts/contradictions. Results obtained show that learning electrochemistry involves both algorithmic and conceptual problems. On Posttest 1, 93% of the experimental group students responded correctly, in contrast to 39% of the control group. On Posttest 2, 39% of the experimental group responded correctly, in contrast to 0% of the Control group. The difference in performance on both posttests is statistically significant (p < 0.001). It is concluded that the teaching experiments facilitated students' understanding (progressive transitions) of electrochemistry.  相似文献

Two decades of educational research in Sweden     

Torsten Husén 《Interchange》1970,1(1):86-98

The article is an attempt to set forth the institutional setting for educational research in Sweden after 1945 and to describe the major directions of research. Governmental school committees began in the 1940's to commission research pertaining to the structure of the compulsory school system and to the objectives and content of the curriculum. As part of the school reform and the attempts to facilitate innovations, the first research institute linked with teacher-training was established in the 1950's. Since the beginning of the 1960's, the National Board of Education has maintained a Bureau of Research and Development. Finally, the proper role of the researcher in his relationship to the policy-makers is discussed on the basis of Swedish experiences.

Résumé L'article tente de décrire le cadre institutionnel pour les recherches dans le domaine d'éducation en Suède après 1945 et de montrer les tendances principales de ces recherches. Ce fut dans les années quarante que des comités gouvernementaux scolaires commencèrent à commander des recherches ayant rapport au système scolaire obligatoire, aux objectifs et au contenu du programme d'études. Le premier institut de recherches lié à l'instruction des enseignants fut établi dans les années cinquante comme une partie de la réforme scolaire et des tentatives de faciliter l'innovation. Le Ministère d'Education National entretient, depuis le commencement des années soixante, le Service de Recherche et de Développement. Enfin, on traite, en prenant les expériences suédoises comme base, le meilleur rôle du chercheur à l'égard de son rapport avec les architectes de la politique.
