A Cross-Age Study of the Understanding of Three Genetic Concepts: How Do They Image the Gene, DNA and Chromosome?     

Arzu Saka  Lale Cerrah  Ali Rıza Akdeniz  Alipaşa Ayas 《Journal of Science Education and Technology》2006,15(2):192-202

The study was carried out with 175 Turkish students by using drawings at different ages understanding of gene, DNA and chromosome concepts. Students from 8th, 9th, 11th grades and, science and biology student teachers were simply asked to draw the structure of gene, DNA and chromosome in a cell and also to give explanations about these three concepts. Differences in understanding between the age groups were found to be significant for the concepts of gene and DNA. None of the groups exhibit sound understanding and regardless of the age levels, students in all groups had alternative ideas about the three concepts investigated.  相似文献   

Pedro Gutiérrez Bueno’s Textbooks: Audiences, Teaching Practices and Chemical Revolution     

José Ramón Bertomeu Sánchez  Antonio García Belmar 《Science & Education》2006,15(7-8):693-712

Pedro Gutiérrez Bueno wrote two editions of a chemistry textbook between 1788 and 1802. The paper offers a comparative view of both editions taking into account Gutiérrez Bueno’s biography, his intended audience and the changes related to the so-called chemical revolution. Some conclusions are at odds with common images about scientific revolutions and the role of textbooks in science. The analysis aims to shed some light on the multiple historical forces shaping textbooks and the way in which scientific change is assimilated by their writers.

‘Approaches to the Teaching of Special Relativity Theory in High School and University Textbooks of Argentina’     

Irene Arriassecq  Ileana María Greca 《Science & Education》2007,16(1):65-86

In this work, we presented an analysis of the representation of the special relativity theory (SRT) in the most used texts in high school, Polimodal level and university level in the teaching in the Argentine Republic, from a historic, epistemological and didactic perspective. The results show that none of the analyzed texts would allow a contextualized approach on such theory.  相似文献   

Exploration De La Résilience éducationnelle Chez Des Enseignants

AN EXPLORATION OF THE EDUCATIONAL RESILIENCE OF TEACHING STAFF – This study focuses on the degree of resilience displayed by teaching staff with the aim of promoting their professional development and preventing job-related exhaustion. Seven underprivileged schools in Montreal were selected, and 24 teaching staff with contrasting personal profiles were interviewed on the subject of their work. The Alceste software was used to analyse the conversations, which revolved around techniques applied when dealing with critical incidents. The main analysis identified five different discourses among the respondents. Three of these were associated with the more resilient of the teachers and two were associated with the more vulnerable ones. Resilient teaching staff characteristically discussed dealing with aggressive behaviour, the teaching-learning relationship and the subject of social relationships, whereas vulnerable teaching staff focused on work beyond the classroom, people in positions of higher authority and the community. The authors note that teachers who are just embarking on their careers appear more vulnerable than more experienced teaching staff, which suggests that more resources should be provided to support teachers in their profession.  相似文献   

Locus and nature of perceptual phonological deficit in Spanish children with reading disabilities     

Ortiz R  Jiménez JE  García Miranda E  Guzmán Rosquete R  Hernández-Valle I  Rodrigo M  Estévez A  Díaz A  Hernández Expósito S 《Journal of learning disabilities》2007,40(1):80-92

The aims of this study were (a) to determine whether Spanish children with reading disabilities (RD) show a speech perception deficit and (b) to explore the locus and nature of this perceptive deficit. A group of 29 children with RD, 41 chronological age-matched controls, and 27 reading ability-matched younger controls were tested on tasks of speech perception. The effect of linguistic unit (word vs. syllable) and type of phonetic contrast (voicing, place and manner of articulation) were analyzed in terms of the number of errors and the response time. The results revealed a speech perception deficit in Spanish children with RD that was independent of the type of phonetic contrast and of linguistic unit.  相似文献   

Evaluation and publication delay in Ibero-American scientific journals     

Jon Zabala  Borja González-Albo  Ana García-García  Aurora Garrido-Domínguez  José Ignacio Vidal-Liy  Luis R. Álvarez-Díez  Soledad Hernando-Tundidor  Yara Mostazo-Fernández  Teresa Abejón 《Learned Publishing》2023,36(2):205-216

This article analyses the review, acceptance and publication dates of a sample of 21,890 articles from 326 Ibero-American scientific journals from all subject areas and countries included in the Latindex Catalogue 2.0 and published between 2018 and 2020 (freely available as an open access dataset). The aim is to discover evaluation and publication times. The evaluation process takes a median of 110 days, the publication process, a median of 82 days, and the whole process, a median of 224 days. Statistical differences are found according to periodicity, subject areas, countries, existence of a printed version and article type (Call for Papers or General articles). From the data we find that the delay in publication is longer than publishers themselves report to the DOAJ. STEM areas present the most similarity in publication patterns, having a higher number of evaluation days (Ed) than publication days (Pd); Arts and Humanities present the opposite pattern, with a higher Pd than Ed. In the case of Social Sciences, the times are similar. General articles and Call for Papers articles differ in terms of Ed, but not Pd, indicating that Call for Papers revisions are faster.  相似文献

Determinants of public engagement on municipal Facebook pages     

Concetta Metallo  Benedetta Gesuele  Ana-María Ríos 《The Information Society》2020,36(3):147-159

Abstract

This article analyzes the determinants of public engagement on the Facebook pages of municipalities. The sample consists of 170 Italian and Spanish municipalities that used Facebook in 2014. The findings show that posting a lot of information on municipal Facebook pages does not increase the engagement of citizens. Also, frequent posting of information per se does not engage public engagement. However, if the posts are published when public can pay attention to them (e.g., off days), the likelihood of public engagement increases. Furthermore, the citizens’ engagement on municipal Facebook page depends on the level of citizens’ income – there is a negative relationship between citizens’ income and the level of participation.  相似文献
