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.

The second year of life as a developmental turning point: Implications for «sensitive» caretaking     

André Vyt 《European Journal of Psychology of Education - EJPE》1989,4(2):145-158

In the context of the transactional view on development, important changes in the second year of life are highlighted which demand parental adaptations in caregiving practice. The discontinuous growth of enriched cognitive functions in the toddler, as exemplified by Piagetian theory on development of intentionality and symbolic thinking and by recent findings about the emergence of self-awareness and mastery-motivation, meshes with changes in caregiving dimensions. The caregiver, seen as a catalyst for the development of cognitive and social competence must adjust himself to the developmental tasks the infant is coping with. The concept of sensitivity is examined in terms of two important aspects: the social and the didactic. From a Vygotskian standpoint, didactic strategies are very important for cognitive competence. Parents have to facilitate self-initiated learning and to adjust to the infant’s increasing cognitive functions. The influence of a didactic «matching» on overall parent-infant interaction quality, and especially on the quality of attachment, is stressed.  相似文献   

The role of student-generated externalizations in strategic multimedia learning and how current (web-)technology fails to support learner engagement     

Rolf Ploetzner  Benjamin Fillisch  Patrick-André Gewald  Tatjana Ruf 《Interactive Learning Environments》2016,24(7):1610-1628

In two studies, we investigated how learning strategies can support learning from multimedia. In the first study, 112 students learned from a web-based learning environment. On the basis of a strategy, one group of students took typewritten notes. The second group of students wrote a summary. Producing typewritten notes did not benefit learning any more than writing a summary. In the second study, 100 students learned the same subject matter from print. On the basis of a strategy, the first group produced written notes, the second group highlighted, wrote notes, and produced sketches. The third group wrote a summary. The students who highlighted, wrote notes, and produced sketches outperformed the other students. The students who produced written notes only did not learn more successfully than those who wrote a summary. The results suggest that externalizations in general and sketches in particular may play an important role in multimedia learning.  相似文献   

Facilitating small-group learning: A comparison of student and staff tutors' behavior     

Jos H. C. Moust  Henk G. Schmidt 《Instructional Science》1994,22(4):287-301

This study focused on students' observations of student and staff tutors' behavior during two academic courses, using a thirtynine-item rating scale. The study took place within an integrated problem-based law curriculum. Six major factors in tutors' behavior were identified. Differences between student and staff tutors' performance were investigated. The results showed that student tutors were better at understanding the nature of the problems students face in attempting to master the subject-matter. Student tutors were also more interested in students' daily lives, study experiences and personalities. In addition, student tutors referred to end-of-course examinations more frequently than staff tutors to direct student learning. Alternatively, staff tutors used their subject-matter expertise more often and displayed more authoritarian behavior than student tutors. No differences were found with respect to tutors' focus on cooperation among group members. The results are interpreted in terms of the nature of the knowledge and experiences of students and staff with regard to problem-based learning and its requirements.  相似文献   

Cumulative stress and substantiated maltreatment: the importance of caregiver vulnerability and adult partner violence   总被引：1，自引：0，他引：1  

Wekerle C  Wall AM  Leung E  Trocmé N 《Child abuse & neglect》2007,31(4):427-443

OBJECTIVE: Our goal is to assess the effect of caregiver vulnerabilities, singly and in combination, on the substantiation of child abuse (physical, sexual) and neglect, while controlling for relevant background variables. We test the moderator role of adult partner violence in qualifying the relationship between caregiver vulnerabilities and maltreatment substantiation. METHOD: Secondary analyses of the 1998 Canadian Incidence Study of Reported Child Maltreatment (CIS) are used to predict child protective service investigation substantiation versus non-substantiation from a range of caregiver vulnerability factors. Involvement in partner violence was examined as a moderator in the relation between caregiver vulnerabilities and maltreatment substantiation. The CIS is an epidemiological survey of first-reported cases to child protective services, using a random sample of child welfare agencies across Canada. Child welfare workers completed a research form on the child, primary caregiver, family, perpetrator, severity and type of maltreatment, as well as services and court outcomes. All maltreatment classifications were assigned according to the Canadian legal definition of child abuse and neglect. Hierarchical logistic regression analyses were used, with stepped entry of: (1) demographic factors, socioeconomic disadvantage, and caregiver's own history of maltreatment; (2) caregiver vulnerability factors; (3) involvement in partner violence; (4) the interaction between caregiver vulnerability and partner violence. RESULTS: Caregiver substance abuse was found to be the single most potent kind of caregiver vulnerability in predicting maltreatment substantiation. When the total number of vulnerabilities was used as the predictor, prediction across all types of maltreatment increased, especially for substantiated neglect. Analyses also showed that the presence of partner violence in the home exacerbated the effect of caregiver vulnerability on substantiation. CONCLUSIONS: The total number of caregiver vulnerabilities was the best predictor of the substantiation of child abuse and neglect. This relationship was moderated by the existence of partner violence: high caregiver vulnerability and high partner violence increased the likelihood of substantiation versus non-substantiation. These results suggest that caregiver issues should be considered in tandem with partner relationships. Among child welfare cases, caregiver vulnerability and partner violence are critical targets for child maltreatment prevention and early child protective services intervention.  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   

Adolescents’ Friendships,Academic Achievement,and Risk Behaviors: Same-Behavior and Cross-Behavior Selection and Influence Processes     

Mariola C. Gremmen  Christian Berger  Allison M. Ryan  Christian E.G. Steglich  René Veenstra  Jan K. Dijkstra 《Child development》2019,90(2):e192-e211

This study examined to what extent adolescents’ and their friends’ risk behaviors (i.e., delinquency and alcohol use) hinder or promote their academic achievement (grade point average [GPA]), and vice versa. Longitudinal data were used (N = 1,219 seventh- to ninth-grade adolescents; M_age = 13.69). Results showed that risk behaviors negatively affected adolescents’ GPA, whereas GPA protected against engaging in risk behaviors. Moreover, adolescents tended to select friends who have similar behaviors and friends’ behaviors became more similar over time (same-behavior selection and influence). Furthermore, although same-behavior effects seemed to dominate, evidence was found for some cross-behavior selection effects and a tendency in seventh grade for cross-behavior influence effects. Concluding, it is important to investigate the interplay between different behaviors with longitudinal social network analysis.  相似文献   

The Development of Empathic Concern in Siblings: A Reciprocal Influence Model     

Marc Jambon  Sheri Madigan  André Plamondon  Ella Daniel  Jennifer M. Jenkins 《Child development》2019,90(5):1598-1613

This study utilized actor–partner interdependence modeling to examine the bidirectional effects of younger (M_age = 18 months) and older siblings (M_age = 48 months) on later empathy development in a large (n = 452 families), diverse (42% immigrant) Canadian sample. Controlling for parenting, demographic characteristics, sibling relationship quality, and within-child stability in empathic concern, both younger and older siblings’ observed empathic concern uniquely predicted relative increases in the other's empathy over a period of 18 months. The strength of the partner effects did not differ by birth order. Sex composition moderated the younger sibling partner effect, whereas age gap moderated the older sibling partner effect. This study highlights the important role that siblings play in enhancing the development of care and concern for others.  相似文献
